Patent Application
20230083035
This application is based on and claims priority under 35 USC119 from Japanese Patent Application No. 2021-148964 filed on Sep. 13, 2021, the contents of which are incorporated herein by reference.
The disclosure relates to a tool and a binding machine.
Some tools such as a reinforcing bar binding machine, a nailing machine and a screw fastener may have a hook attached to a tool body or a grip. This hook can be used to hook the tool on a belt mounted on worker's trousers when the tool is not used or when the tool is carried, or can be used to hook the tool on a scaffold or a stepladder placed on the site or the like when the tool is not used.
For example, PTL 1 describes a screw fastener in which a pair of upper and lower insertion holes are formed on a side surface of a head portion and a hook device is attached to the insertion holes. Further, PTL 2 describes a driving tool in which a hook support member is fixed to a rear portion of a grip formed at one end of a body and a hook formed by connecting a hook portion and a slide shaft portion in a bent shape is attached to this hook support member.
By the way, for example, at a work site where a bar arrangement work for arranging reinforcing bars on a wall or a pillar or the like, and a binding work for binding the arranged reinforcing bars with a wire are performed, when the bar arrangement work and the binding work are alternately performed, a tool (reinforcing bar binding machine) is often hung on a worker's belt or is placed on a scaffold during the bar arrangement work. However, rather than hanging the tool on the belt or placing the tool on the scaffold, it is advantageous in terms of work efficiency to hook the tool on the arranged reinforcing bars because the next work (binding work) can be smoothly performed.
[PTL 1] JP2006-150503A
[PTL 2] JP4,877,488B
However, when the hook is attached to the side surface of the main body so that the opening of the hook faces the front (of the main body) as in the tool disclosed in PTL 1, there is a problem that when the worker hooks the tool on the reinforcing bar or the like according to the orientation of the opening of the hook and releases his hand, the tool is significantly titled and becomes unstable, and the tool easily falls from the reinforcing bar. Further, since the tool is significantly tilted (moved) when the worker releases his hand from the tool, there is a problem that the tool easily comes into contact with the surrounding reinforcing bar or the like, and the surrounding reinforcing bar and the tool itself are damaged.
Further, in the tool disclosed in PTL 2, the hook is provided on the lower side of the gripping unit. Therefore, when hooking the hook on the reinforcing bar or the stepladder or the like, there is a problem that the worker needs to hook the hook while turning over his wrist, which was difficult to execute, and the worker cannot proceed the next work quickly.
The disclosure has been made to solve the above problems, and an object thereof is to provide a tool and a binding machine that are easily hooked on a hooked member such as a reinforcing bar at a work site and are not significantly tilted when hooked.

Meanwhile, since the first hook attachment units 210b, 210c, 210e have the same configurations as the above-mentioned first hook attachment unit 210a and the like, detailed description thereof will be omitted.
As shown in
As shown in
In the present embodiment, the engaging piece 202 of the first hook 200A is fitted into the engaging hole 212d of the first hook attachment unit 210d, and the screws 206, 206 are screwed into the screw holes 214d, 214d of the first hook attachment unit 210d through the insertion holes 204, 204, so that the first hook 200A is fixed to the main body 10 (the cover unit 250). At this time, as shown in
As shown in
Meanwhile, in the present embodiment, the second hook attachment unit 310 is provided on the left surface 10b side of the main body 10. However, the second hook attachment unit 310 may be provided on the right surface 10c side of the main body 10 or may be provided on both the left surface 10b and the right surface 10c of the main body 10. Further, the second hook attachment unit 310 may be provided directly on the main body 10 instead of the cover unit 250.
The second hook 300 is a part for hooking the reinforcing bar binding machine 1A on the reinforcing bar S from the left surface 10b side. Similar to the first hook 200A, the second hook 300 is formed of a flat plate member bent into a U-shape on the side surface. In the present embodiment, the second hook 300 has a bifurcated shape in which a slit is formed along the longitudinal direction thereof, but the second hook 300 is not limited to this shape. Meanwhile, similar to the first hook 200A, the second hook 300 does not necessarily have to be U-shaped, and may be, for example, J-shaped, L-shaped, inverted C-shaped, or crank-shaped.
As shown in
In the present embodiment, the engaging piece 302 of the second hook 300 is fitted into the engaging hole 312 of the second hook attachment unit 310, and the screws 306, 306 are screwed into the screw holes 314, 314 of the second hook attachment unit 310 through the insertion hole 304, 304, so that the second hook 300 is fixed to the left surface 10b of the main body 10 (the cover unit 250).
In this case, when the main body 10 is viewed from the front (front view), as shown in
Here, the center of gravity C of the reinforcing bar binding machine 1A is determined by the weights of the main body 10, the curl forming unit 5, the magazine 2, the gripping unit 11, and the battery 15 and the arrangement thereof. The magazine 2 which is heavier than other configurations (the curl forming unit 5, the gripping unit 11, and the like) by accommodating the wire W is provided in front of the lower surface 10e of the main body 10. Therefore, as shown in
As shown in
The curl forming unit 5 includes a curl guide 50 for giving a curl to the wire W fed by the wire feeding unit 3, and a guiding guide 51 for guiding the wire W having the curl made by the curl guide 50 to the twisting unit 7. The curl guide 50 and the guiding guide 51 of the curl forming unit 5 are provided at an end portion on the front side of the main body 10. In the reinforcing bar binding machine 1A, the path of the wire W fed by the wire feeding unit 3 is regulated by the curl forming unit 5, so that the wire W is wound around the reinforcing bar S.
As shown in
The twisting unit 7 includes a wire locking body 70 to which the wire W is locked, and a rotating shaft 72 for operating the wire locking body 70. The driving unit 8 includes a motor 80 and a reducer 81 that decelerates and amplifies a torque. In the twisting unit 7 and the driving unit 8, the rotating shaft 72 and the motor 80 are connected via the reducer 81, and the rotating shaft 72 is driven by the motor 80 via the reducer 81. The wire locking body 70 includes a sleeve 71 that operates a first side hook and a second side hook (which are not shown) in conjunction with the rotational operation of the rotating shaft 72.
The wire W fed by the wire feeding unit 3 is guided to the curl forming unit 5 through the wire locking body 70. Then, the wire W is curled by the curl forming unit 5, and a leading end side of the wire W guided to the twisting unit 7 is locked so as not to come off from the wire locking body 70. Subsequently, when the wire W is cut by the cutting unit 6, the sleeve 71 moves in the forward direction to bend the tip side of the wire W locked by the wire locking body 70 and the terminal side of the wire W cut by the cutting unit 6 toward the reinforcing bar S.
When the sleeve 71 further moves in the forward direction after the tip side and the terminal side of the wire W are bent toward the reinforcing bar S, the sleeve 71 rotates in conjunction with the rotating shaft 72, and the wire W locked by the wire locking body 70 is twisted.
Usage Example of First Hook 200A
Usage Example of Second Hook 300
Modified Example of Second Hook Attachment Unit 310
Meanwhile, the second hook attachment unit 310 can be attached on the left surface 10b side and the right surface 10c side of the main body 10 and is not limited to the attachment position shown in
As shown in
According to the first embodiment, the first hook 200A is attached to the first hook attachment unit 210a and the like so that the first hook 200A is located on the upper surface 10a side of the main body 10, and the opening 201 of the first hook 200A faces the front side. Therefore, when the first hook 200A is attached to the first hook attachment unit 210a and the like, after the binding work to the reinforcing bar S or the like located in front of the worker, the worker can hook the reinforcing bar binding machine 1A on the reinforcing bar S or the like with a small number of movements while tilting the front end side of the main body 10 having the curl forming unit 5 and the twisting unit 7 downward and without turning over his wrist. Therefore, when the reinforcing bar binding machine 1A is repeatedly used and hooked when not in use, the work efficiency can be improved and the work load on the worker can be reduced.
Further, since the reinforcing bar binding machine 1A is configured so that the magazine 2 for accommodating the wire W and the gripping unit 11 are provided on the lower surface 10e side of the main body 10, the center of gravity C of the reinforcing bar binding machine 1A is located below the main body 10, more specifically, near the magazine 2. Therefore, when such a reinforcing bar binding machine 1A is hooked on the reinforcing bar S or the like via the first hook 200A attached to the first hook attachment unit 210a and the like, due to the relationship with the position of the center of gravity, the reinforcing bar binding machine 1A does not become significantly tilted (moved) and unstable, and can be stably held. That is, since the reinforcing bar binding machine 1A is stably hooked on the reinforcing bar S or the like, problems such as the reinforcing bar binding machine 1A falling from the reinforcing bar are less likely to occur.
Further, the second hook 300 is attached to the second hook attachment unit 310 so that the second hook 300 is provided on the left surface 10b side of the main body 10, and the opening 301 of the second hook 300 faces downward. Therefore, when the reinforcing bar binding machine 1A is hooked on the reinforcing bar S or the like, the reinforcing bar binding machine 1A is held so that the left surface 10b in the front and rear direction of the main body 10 is substantially parallel to the reinforcing bar S or the like. Therefore, the amount of protrusion of the main body 10 with respect to the reinforcing bar S or the like can be reduced, and even when the reinforcing bar binding machine 1A is hooked on the reinforcing bar S, the reinforcing bar binding machine 1A does not interfere with the work, and smooth movement and work can be performed at the work site.
And, according to the first embodiment, the first hook attachment unit 210a and the like and the second hook attachment unit 310 having the above-mentioned effects are provided in one reinforcing bar binding machine 1A. Therefore, the work efficiency can be improved and the work load on the worker can be reduced in various situations at various work sites.
Further, according to the first embodiment, the second hook 300 is attached to the second hook attachment unit 310 so that the second hook 300 does not block the opening 201 of the first hook 200A, and the second hook 300 is attached to the second hook attachment unit 310 so that the second hook 300 does not protrude from the upper surface 10a of the main body 10 or the guide surface 250a of the cover unit 250. Therefore, it is possible to prevent the second hook 300 from becoming an obstacle when the first hook 200A is hooked on the reinforcing bar S.
Further, according to the first embodiment, since the cover unit 250 and the guide surface 250a are provided, the reinforcing bar S can be guided while sliding in the opening 201 of the first hook 200A, and therefore, the first hook 200A can be easily hooked on the reinforcing bar S. Further, since the cover unit 250 is provided, it is possible to prevent the reinforcing bar S from coming into direct contact with the main body 10, thereby preventing the damage of the main body 10.
A reinforcing bar binding machine 1B according to a second embodiment is different from the reinforcing bar binding machine 1A of the first embodiment in that a hook 200B can be moved and retracted to the rear side of the main body 10. Meanwhile, the components having substantially the same function as the reinforcing bar binding machine 1A according to the above-mentioned embodiment are designated by the same reference numerals, and duplicate description will be omitted.
Configuration Example of Reinforcing Bar Binding Machine 1B
As shown in
As shown in
The lock plate 700 has a left portion 700a and a right portion 700b erected downward from both end portions in the left and right direction. As shown in
As shown in
A folded-back portion 208 of the hook 200B is attached to a central portion of an upper surface of the flat plate member 412 by a stopper 420. The folded-back portion 208 is a portion that folds back and extends from a base end portion of the hook 200B toward a curved portion on the opposite side. The hook 200B is configured to be pivotable around the axis of the stopper 420, so that the orientation of the hook 200B can be changed.

As shown in
As shown in
Operation Example of Reinforcing Bar Binding Machine 1B
Next, an operation at the time of moving the hook 200B from the usage position P1 on the upper surface 10a side of the main body 10 to the retreat position P2 on the rear surface 10d side of the main body 10 will be described.
As shown in
Subsequently, the worker grips the hook 200B with the other hand and rotates the hook 200B backward, as shown in
Subsequently, when the hook 200B pivots from the usage position P1 to the retreat position P2 with the third shaft 724 as a fulcrum, since the lock portion 414 is urged forward by the tension spring 726, the second recessed portion 414b of the lock portion 414 engages with the dowel 730. In this way, the hook 200B is held at the retreat position P2.
Subsequently, as shown in
As described above, according to the second embodiment, for example, in a case where the hook 200B on the upper surface 10a of the main body 10 becomes an obstacle during the binding work, the hook 200B can be retracted from the upper surface 10a of the main body 10 to the rear surface 10d side and the like. In this way, the work efficiency can be improved. Meanwhile, although, in the second embodiment, the first hook attachment unit 210 has been moved to the rear surface 10d side, the first hook attachment unit 210 may be configured to be movable to the left surface 10b side or the right surface 10c side. When the hook 200B is moved from the upper surface 10a side of the main body 10 to the left surface 10b side, the hook 200B can be used as a hook to be hooked on the reinforcing bar S or the like. Naturally, the hook attachment unit provided on the left surface 10b side or the right surface 10c side of the main body 10 may be configured to be movable to the upper surface 10a side of the main body 10. In this way, since one hook 200B can be used properly according to the situations of various work sites, the cost reduction can be achieved compared with the case of using two hooks.
A reinforcing bar binding machine 1C of a third embodiment is different from the reinforcing bar binding machine 1A of the first embodiment in that a hook 200C can be retracted to a side surface side of the main body 10 when the hook 200C is not used. Meanwhile, the components having substantially the same function as the reinforcing bar binding machine 1A according to the above-mentioned embodiment are designated by the same reference numerals, and duplicate description will be omitted.
Configuration Example of Reinforcing Bar Binding Machine 1C
The reinforcing bar binding machine 1C includes hook attachment units 510a, 510b for supporting the hook 200C to be movable from the usage position P1 (see
The hook member 202a is attached to the hook attachment unit 510a so that the hook member 202a can be pivoted from the upper surface 10a side of the main body 10 to the left surface 10b side. The hook attachment unit 510a is configured by, for example, a flat hinge, and is fastened to the guide surface 250a and the left portion 250c of the cover unit 250 by screws 512 with a base end side of the hook member 202a inserted in its pipe.
The hook member 202b is attached to the hook attachment unit 510b so that the hook member 202b can be pivoted from the upper surface 10a side of the main body 10 to the right surface 10c side. The hook attachment unit 510b is configured by, for example, a flat hinge, and is fastened to the guide surface 250a and the right portion 250d of the cover unit 250 by screws 514 with a base end side of the hook member 202b inserted in its pipe.
The hook 200C is attached to the hook attachment units 510a, 510b so that an opening 201c of the hook 200C including the hook members 202a, 202b, into which the reinforcing bar S is inserted, faces the front side in the front and rear direction of the main body 10.
As shown in
The hook 200C is urged to the rear of the main body 10 by springs 516, 518. As shown in
Operation Example of Reinforcing Bar Binding Machine 1C
As shown in
Subsequently, as shown in
As described above, according to the third embodiment, for example, when the hook 200C on the upper surface 10a of the main body 10 becomes an obstacle during the binding work, the hook 200C can be retracted from the upper surface 10a of the main body 10 to the left surface 10b and the like. In this way, the work efficiency can be improved.
In a reinforcing bar binding machine 1D according to a fourth embodiment, the hook attachment unit 210a and the like are provided only on the upper surface 10a side of the main body 10. Meanwhile, the components having substantially the same function as the reinforcing bar binding machine 1A according to the above-mentioned embodiment are designated by the same reference numerals, and duplicate description will be omitted.
As shown in
The hook attachment unit 210d and the like are provided along the front and rear direction (longitudinal direction) of the guide surface 250a of the cover unit 250. The hook 200A is attached to the hook attachment unit 210d and the like so that the opening 201 of the hook 200A faces the front side in the front and rear direction of the main body 10. Meanwhile, as described in the first embodiment, the number of the hook attachment unit 210d and the like is not limited to five, and any number can be provided. Further, the hook attachment unit 210d and the like may be provided directly on the upper surface 10a of the main body 10.
As shown in
As described above, since the reinforcing bar binding machine 1D of the fourth embodiment is configured so that the magazine 2 for accommodating the wire W and the gripping unit 11 are provided on the lower surface 10e side of the main body 10, the center of gravity C of the reinforcing bar binding machine 1D is located below the main body 10, more specifically, near the magazine 2. Therefore, when such a reinforcing bar binding machine 1D is hooked on the reinforcing bar S or the like via the first hook 200A attached to the hook attachment unit 210a to 210e, due to the relationship with the position of the center of gravity, the reinforcing bar binding machine 1D does not become significantly tilted (moved) and unstable, and can be stably held. That is, since the reinforcing bar binding machine 1D is stably hooked on the reinforcing bar S or the like, problems such as the reinforcing bar binding machine 1D falling from the reinforcing bar are less likely to occur. Further, the hook 200A is attached to the hook attachment unit 210a to 210e so that the hook 200A is located on the upper surface 10a side of the main body 10, and the opening 201 of the hook 200A faces the front side. Therefore, when the hook 200A is attached to the hook attachment unit 210a to 210e, after the binding work to the reinforcing bar S located in front of the worker, the worker can hook the reinforcing bar binding machine 1D on the reinforcing bar S with a small number of movements while tilting the front end side of the main body 10 having the curl forming unit 5 downward and without turning over his wrist. In this way, when the reinforcing bar binding machine 1D is repeatedly used and hooked when not in use, the work efficiency can be improved and the work load on the worker can be reduced.
In a reinforcing bar binding machine 1E according to a fifth embodiment, a hook attachment unit 310 is provided only on the left surface 10b side of the main body 10. Meanwhile, the components having substantially the same function as the reinforcing bar binding machine 1A according to the above-mentioned embodiment are designated by the same reference numerals, and duplicate description will be omitted.
As shown in
The hook attachment unit 310 is provided on the overhang portion 250e of the cover unit 250. The hook 300 is attached to the hook attachment unit 310 so that the opening 301 of the hook 300 faces the center of gravity C of the reinforcing bar binding machine 1E (see
As described above, since the reinforcing bar binding machine 1E of the fifth embodiment is configured so that the magazine 2 for accommodating the wire W and the gripping unit 11 are provided on the lower surface 10e side of the main body 10, the center of gravity C of the reinforcing bar binding machine 1E is located below the main body 10, more specifically, near the magazine 2. Therefore, when such a reinforcing bar binding machine 1E is hooked on the reinforcing bar S or the like via the second hook 300 attached to the hook attachment unit 310, due to the relationship with the position of the center of gravity, the reinforcing bar binding machine 1E does not become significantly tilted (moved) and unstable, and can be stably held. That is, since the reinforcing bar binding machine 1E is stably hooked on the reinforcing bar S or the like, problems such as the reinforcing bar binding machine 1E falling from the reinforcing bar S or the like are less likely to occur. Further, the hook 300 is attached to the hook attachment unit 310 so that the hook 300 is located on the left surface 10b side of the main body 10, and the opening 301 of the hook 300 faces the lower side. Therefore, when the reinforcing bar binding machine 1E is hooked on the reinforcing bar S or the like, the reinforcing bar binding machine 1E is held so that the left surface 10b in the front and rear direction of the main body 10 is substantially parallel to the reinforcing bar S or the like. Therefore, the amount of protrusion of the main body 10 with respect to the reinforcing bar S or the like can be reduced, and even when the reinforcing bar binding machine 1E is hooked on the reinforcing bar S, the reinforcing bar binding machine 1E does not interfere with the work, and smooth movement and work can be performed at the work site.
A reinforcing bar binding machine 1F according to a sixth embodiment is different from the reinforcing bar binding machine 1A of the first embodiment in that the magazine 2 is provided on the side surface side of the main body 10. Meanwhile, the components having substantially the same function as the reinforcing bar binding machine 1A according to the above-mentioned embodiment are designated by the same reference numerals, and duplicate description will be omitted.
As shown in
Further, the reinforcing bar binding machine 1F includes the hook attachment unit 210 located on the upper surface 10a side of the main body 10 and to which the U-shaped first hook 200A opened at one side can be attached. Although, in the present embodiment, the first hook 200A is configured to have a U-shape on the side surface, the first hook 200A does not necessarily have to be U-shaped, and may be, for example, J-shaped, L-shaped, inverted C-shaped, or crank-shaped.
The magazine 2 is provided at a position closer to the right surface 10c side of the main body 10 in order to avoid the twisting unit 7 and the driving unit 8 and the like arranged on the left side inside the main body 10. The magazine 2 is configured by a space portion that can accommodate the reel 20 around which the wire W is wound.
Further, as shown in
The first hook attachment unit 210 is provided on the upper surface of the magazine cover unit 22. The first hook 200A is attached to the first hook attachment unit 210 so that the opening 201 of the first hook 200A faces the front side in the front and rear direction of the main body 10. The first hook 200A is attached to the magazine cover unit 22 by fitting the engaging piece 202 (see
Meanwhile, as described in the first embodiment, a plurality of first hook attachment units 210 may be provided, or the first hook attachment unit 210 may be provided directly on the upper surface 10a of the main body 10. Further, as shown in
Further, as described in the first embodiment and the like, the second hook attachment unit 310 may be provided on at least one surface side of the left surface 10b and the right surface 10c of the main body 10. In this case, when the main body 10 is viewed from the front (front view), the second hook 300 is attached to the second hook attachment unit 310 so that the second hook 300 does not block the opening 201 of the first hook 200A attached to the first hook attachment unit 210. Further, the second hook 300 is attached to the second hook attachment unit 310 so that the second hook 300 does not protrude from the upper surface 10a of the main body 10 or the magazine cover unit 22.
Further, the second hook 300 is attached to the second hook attachment unit 310 so that the opening 301 of the second hook 300 is located on the lower side in the front and rear direction of the reinforcing bar binding machine 1F and faces a center of gravity D of the reinforcing bar binding machine 1F. Here, the center of gravity D of the reinforcing bar binding machine 1F is determined by the weights of the main body 10, the curl forming unit 5, the magazine 2, the gripping unit 11, the battery 15 and the like, and the arrangement thereof. In the present embodiment, since the magazine 2 which is one of heavy objects is provided on the rear end portion in the front and rear direction of the main body 10, the magazine 2 is located slightly behind the trigger 12 and is located at a connecting portion between the lower surface 10e of the main body 10 and the upper end portion of the gripping unit 11.
As described above, since the reinforcing bar binding machine 1F of the sixth embodiment is configured so that the magazine 2 is located at the rear end portion in the front and rear direction of the main body 10, the center of gravity D of the reinforcing bar binding machine 1F is located near the magazine 2. Therefore, when such a reinforcing bar binding machine 1F is hooked on the reinforcing bar S or the like via the hook 200A attached to the hook attachment unit 210, due to the relationship with the position of the center of gravity, the reinforcing bar binding machine 1F does not become significantly tilted (moved) and unstable, and can be stably held. That is, since the reinforcing bar binding machine 1F is stably hooked on the reinforcing bar S or the like, problems such as the reinforcing bar binding machine 1F falling from the reinforcing bar S or the like are less likely to occur.
Further, according to the reinforcing bar binding machine 1F, the hook 200A is attached to the hook attachment unit 210 so that the hook 200A is located on the upper surface 10a side of the main body 10, and the opening 201 of the hook 200A faces the front side. Therefore, when the hook 200A is attached to the hook attachment unit 210, after the binding work to the reinforcing bar S or the like located in front of the worker, the worker can hook the reinforcing bar binding machine 1F on the reinforcing bar S or the like with a small number of movements while tilting the front end side of the main body 10 having the curl forming unit 5 and the like downward and without turning over his wrist. Therefore, when the reinforcing bar binding machine 1F is repeatedly used and hooked when not in use, the work efficiency can be improved and the work load on the worker can be reduced.
Although the preferred embodiments of the disclosure have been described in detail with reference to the accompanying drawings, the technical scope of the disclosure is not limited to such examples. For example, although the above-mentioned embodiments have described the case where the tool is the reinforcing bar binding machine 1A or the like, the example of the tool includes a nailing machine and a screw fastener and the like, in addition to the reinforcing bar binding machine 1A or the like. The hook attachment unit described above can also be applied to a nailing machine and a screw fastener and the like.
In the above-mentioned embodiments, the first hook attachment unit 210a and the like are configured by the engaging hole 212a into which the engaging piece 202 of the first hook 200A is fitted, and the screw hole 214a into which the screw 206 is screwed. However, the disclosure is not limited to such configurations. For example, a known fastening means such as a fitting type may be applied instead of the screw fastening. Further, the same applies to the other second hook attachment unit 310 and the like described in the above-mentioned embodiments.

According to the tool of the disclosure, the hook is attached to the first hook attachment unit so that the hook is located on the upper surface side of the main body, and the opening of the hook faces the front side. Therefore, when the hook attached to the first hook attachment unit is hooked on a hooked member such as a reinforcing bar, a wall or a pillar located in front of a worker, a worker can hook the hook on the hooked member with a small number of movements while tilting the front end side of the main body having the output section downward and without turning over his wrist. Therefore, when the tool is repeatedly used and hooked when not in use, the work efficiency can be improved and the work load on the worker can be reduced.
Further, the hook is attached to the second hook attachment unit so that the hook is located on the side surface side of the main body, and the opening of the hook faces the lower side. Therefore, when the tool is hooked on a hooked member such as a reinforcing bar or a wall, the tool is held so that the side surface in the longitudinal direction of the main body is substantially parallel to the reinforcing bar or the wall or the like. In this way, the amount of protrusion of the main body with respect to the hooked member can be reduced, and even when the tool is hooked on the hooked member, the tool does not interfere with the work, and smooth movement and work can be performed at the work site.
Further, since the first hook attachment unit and the second hook attachment unit having the above-mentioned effects are provided in one tool, the work efficiency can be improved and the work load on the worker can be reduced in various situations at various work sites.

The hook is attached to the hook attachment unit so that an opening of the hook faces the front side in the longitudinal direction of the main body.
Since the first binding machine of the disclosure is configured so that the accommodation unit for accommodating the wire and the gripping unit are provided on the lower surface side of the main body, the center of gravity of the binding machine is located below the main body, more specifically, near the accommodation unit. Therefore, when such a binding machine is hooked on a hooked member such as a reinforcing bar via the hook attached to the hook attachment unit, due to the relationship with the position of the center of gravity, the binding machine does not become significantly tilted (moved) and unstable, and can be stably held. That is, since the binding machine is stably hooked on the hooked member, problems such as the binding machine falling from the reinforcing bar are less likely to occur. Further, the hook is attached to the hook attachment unit so that the hook is located on the upper surface side of the main body, and the opening of the hook faces the front side. Therefore, when the hook is attached to the hook attachment unit, after the binding work to the reinforcing bar located in front of the worker, the worker can hook the binding machine on the reinforcing bar (hooked member) with a small number of movements while tilting the front end side of the main body having the binding unit downward and without turning over his wrist. In this way, when the binding machine is repeatedly used and hooked when not in use, the work efficiency can be improved and the work load on the worker can be reduced.

The binding machine includes a hook attachment unit located on a side surface side of the main body and configured to allow a hook opened at one side attached. The hook is attached to the hook attachment unit so that an opening of the hook faces a center of gravity of the binding machine.
Since the second binding machine of the disclosure is configured so that the accommodation unit for accommodating the wire and the gripping unit are provided on the lower surface side of the main body, the center of gravity of the binding machine is located below the main body, more specifically, near the accommodation unit. Therefore, when such a binding machine is hooked on a hooked member such as a reinforcing bar via the hook attached to the hook attachment unit, due to the relationship with the position of the center of gravity, the binding machine does not become significantly tilted (moved) and unstable, and can be stably held. That is, since the binding machine is stably hooked on the hooked member, problems such as the binding machine falling from the reinforcing bar are less likely to occur. Further, the hook is attached to the hook attachment unit so that the hook is located on the side surface side of the main body, and the opening of the hook faces the lower side. Therefore, when the binding machine is hooked on a hooked member such as a reinforcing bar or a wall, the binding machine is held so that the side surface in the longitudinal direction of the main body is substantially parallel to the reinforcing bar or the wall or the like. In this way, the amount of protrusion of the main body with respect to the hooked member can be reduced, and even when the binding machine is hooked on the hooked member, the binding machine does not interfere with the work, and smooth movement and work can be performed at the work site.
