The disclosure relates to a hand tool, particularly to a synchronously linkable hand tool.
The way to combine two different objects is mostly realized by the cooperation of screws and hand tools. Therefore, hand tools are closely related to us in life and work. Based on this, the inventor has improved related-art hand tools.
Most of the related-art hand tools for locking or unlocking are operated in a single-point-to-single-point manner. For the applications where many places need to be locked or unlocked at the same time, the force cannot be evenly applied, which may cause damage to the workpiece.
In view of this, the inventors have devoted themselves to the above-mentioned related art, researched intensively and cooperated with the application of science to try to solve the above-mentioned problems. Finally, the invention which is reasonable and effective to overcome the above drawbacks is provided.
An object of the disclosure is to provide a synchronously linkable hand tool, which utilizes the first and second driven mechanisms to make the force uniform during locking or unlocking to avoid damage to the workpiece.
To accomplish the above object, the disclosure provides a synchronously linkable hand tool, which includes a base, a rotation mechanism, a first driven mechanism and a second driven mechanism. The rotation mechanism is rotatably connected to the base and includes a driving gear. The first driven mechanism is disposed on the base and includes a first driven gear and a first locking/unlocking member connected to and rotated by the first driven gear. The second driven mechanism is disposed on the base and includes a second driven gear and a second locking/unlocking member connected to and rotated by the second driven gear. The first driven gear and the second driven gear are rotated by the driving gear to synchronously rotate the first locking/unlocking member and the second locking/unlocking member.
The disclosure further has the following functions. The operating time may be shortened and the labor costs may be effectively saved.
The technical contents of this disclosure will become apparent with the detailed description of embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and drawings disclosed herein are to be considered illustrative rather than restrictive.

The base 10 includes a lower casing 11 and an upper casing 12. The middle of the lower casing 11 is formed with a pivot hole 111. Each of two sides of the lower casing 11 is connected with a hollow guide rod 112. An end of each hollow guide rod 112 is fixed onto the lower casing 11. Also, a lower rod connecting hole 113 is separately formed between the pivot hole 111 of the lower casing 11 and each hollow guide rod 112. Further, the sidewall of the lower casing 11 is disposed with multiple threaded rods 114.
The upper casing 12 correspondingly covers the lower casing 11. The middle of the upper casing 11 is formed with a through hole 121 corresponding to the pivot hole 111 in position. Each of two sides of the upper casing 12 is formed with an upper shaft connecting hole 122. Each upper shaft connecting hole 122 is arranged corresponding to each hollow guide rod 112. Also, an upper rod connecting hole 123 is separately formed between the through hole 121 and each upper shaft connecting hole 122 of the upper casing 12. Each upper rod connecting hole 123 is arranged corresponding to each lower rod connecting hole 113. Further, the sidewall of the upper casing 12 is formed with multiple via holes 124. Each via hole 124 is arranged corresponding to each threaded rod 114 to allow a fastener 13 to pass the via hole 124 to lock to the threaded rod 114.
The rotation mechanism 20 is rotatably connected to the middle of the base 10 and includes a driving gear 21, a shaft 22 and a knob 23. The shaft 22 passes through and is fixedly connected with the driving gear 21. An end of the shaft 22 is pivotally connected to the pivot hole 111, and the other end of the shaft 22 passes through and projects from the upper casing 12 to be fixed to the knob 23. In the embodiment, the driving gear 21 is a spur gear.
The first driven mechanism 30 is disposed on the base 10 and located on a side of the rotation mechanism 20 and includes a first driven gear 31 and a first locking/unlocking member 32. In the embodiment, the first driven gear 31 is a spur gear which may be engaged with the driving gear 21. The first locking/unlocking member 32 may be a flathead screwdriver, a Phillips screwdriver, or a polygonal screwdriver. The first locking/unlocking member 32 passes and is fixed to the first driven gear 31 to make the first locking/unlocking member 32 rotate with the first driven gear 31. An end of the first locking/unlocking member 32 is pivotally connected to the upper shaft connecting hole 122, and the other end of the first locking/unlocking member 32 passes through and projects from the hollow guide rod 112.
The second driven mechanism 40 is disposed on the base 10 and located on another side of the rotation mechanism 20, and includes a second driven gear 41 and a second locking/unlocking member 42. In the embodiment, the second driven gear 41 is a spur gear which may be engaged with the driving gear 21. The second locking/unlocking member 42 may also be a flathead screwdriver, a Phillips screwdriver, or a polygonal screwdriver. The second locking/unlocking member 42 passes and is fixed to the second driven gear 41 to make the second locking/unlocking member 42 rotate with the second driven gear 41. An end of the second locking/unlocking member 42 is pivotally connected to another upper shaft connecting hole 122, and the other end of the second locking/unlocking member 42 passes through and projects from another hollow guide rod 112.
In an embodiment, the synchronously linkable hand tool of the disclosure further includes an idle gear set 50 which includes a first idle gear 51 and a second idle gear 52. The first idle gear 51 is arranged between the driving gear 21 and the first driven gear 31, and is pivotally connected between the lower casing 11 and the upper casing 12 of the base 10 through the lower rod connecting hole 113 and the upper rod connecting hole 123. The first idle gear 51 is a spur gear which is engaged with the driving gear 21 and the first driven gear 31. The second idle gear 52 is arranged between the driving gear 21 and the second driven gear 41, and is pivotally connected between the lower casing 11 and the upper casing 12 of the base 10 through the lower rod connecting hole 113 and the upper rod connecting hole 123. The second idle gear 52 is a spur gear which is engaged with the driving gear 21 and the second driven gear 41. As a result, the rotational directions of the first locking/unlocking member 32 and the second locking/unlocking member 42 are the same as that of the knob 23.
