The invention relates to a nail gun nail-box unit, more particularly to a nail gun nail-box unit which can be used for multi-specification nails simultaneously.
Although the nail-box unit for the alternative use of F-shaped nails and U-shaped nails has been developed quite maturely in current nail gun nail-box structures, higher requirements for the universality of nail-box unit in terms of the shape of nails have been come up with during practices as the application field of the nail gun is ceaselessly widened and the number of the shapes of the used nails is increased. Furthermore, it is required in nailing operation that the nail-box unit can not only adapt to F-shaped nails and U-shaped nails, but also can adapt to T-shaped nails simultaneously.
As another example, a nail-box unit of dual-purpose nail guns for T-shaped and U-shaped nails is disclosed in China Publication Patent Number CN2340569Y, the device comprises a groove and a slide box which is positioned on the periphery thereof in slide matching therewith, —the slide box is axially provided with a sleeved space, the wall face of which is apart from the groove so that a U-shaped nail can be arranged, and the surface of one side of the groove and the wall face of the sleeved space of the slide box are provided with a plurality of opposite groove channels which are used for the arrangement of T-shaped nails with different lengths. The technology has the advantage that : the nail-box unit can adapt to T-shaped and U-shaped nails and includes consistent arrangement manner of the nails and simple, convenient arrangement operation of the nails.
However, the prior art described above has the deficiency that: the nail passing groove for T-shaped nails is only arranged at one side of the groove on which a U-shaped nail can straddle and slide; and owing to the unchanged spacing between the nail clip and the groove, the nail-box unit can only adapt to T-shaped nails or F-shaped nails both having one wire diameter, which means narrow application range thereof.
In order to solve the technical problems, the present invention provides a nail gun nail-box unit which can adapt to F-shaped nails, U-shaped nails and T-shaped nails simultaneously. The technical proposal as follow is adopted to solve the above technical problems : a three-in-one nail gun nail-box unit, comprising:
Further, the sidewalls of the accommodation grooves are provided with a plurality of protrusions in order to adapt to T-shaped nails and F-shaped nails with different heights. Further, the bottoms of the first accommodation groove and the second accommodation groove are provided with abrasion-resistant inserts.
Further, one end of the groove and the nail clip is connected with the gun head, while the other end is provided with a support. Further, the U-shaped nail-pushing end of the nail-pushing block is tooth-shaped.
Further, the elastomer is hooked at the end of the nail clip of the nail gun via a hook.
Further, the gun head comprises a gun nozzle, a cover plate and a gun needle, wherein the gun nozzle is formed with a first nail passing groove and a second nail passing groove respectively corresponding to the first accommodation groove and the second accommodation groove, as well as a U-shaped nail passing channel; the gun needle comprises a first branch matched with the first nail passing groove and a second branch matched with the second nail passing groove.
According to the invention, since two sides of the groove are provided with nail passing accommodation grooves, the nail-box unit can adapt to F-shaped and T-shaped nails respectively, and can also adapt to T-shaped nails having two different wire diameters or F-shaped nails having two different wire diameters, therefore, the range of application is widened. And meanwhile, the inner sidewalls of the accommodation grooves are provided with a plurality of protrusions which can adapt to F-shaped and T-shaped nails with different heights.
The nail gun nail-box unit has the advantage of: being capable of adapting to three types of nails, and wide range of use.
Further description is made to the present invention in reference to drawings:
The bottoms of the first accommodation groove 31 and the second accommodation groove 32 are provided with abrasion-resistant inserts 5.
One end of the groove 1 and the nail clip 2 is connected with the gun head, while the other end is provided with a support. The U-shaped nail-pushing end of the nail-pushing block 8 is tooth-shaped.
The elastomer 81 is hooked at the end of the nail clip 2 of the nail gun via a hook. The elastomer 81 is respectively arranged inside two square grooves of the nail clip 2 and is limited by the cover plate at the bottom and screws at the top.
The gun head comprises a gun nozzle 6, a cover plate 9 and a gun needle 7, wherein the gun nozzle is formed with a first nail passing groove 61 and a second nail passing groove 62 respectively corresponding to the first accommodation groove 31 and the second accommodation groove 32, as well as with a U-shaped nail passing channel; the gun needle 7 comprises a first branch 71 matched with the first nail passing groove 61 and a second branch 72 matched with the second nail passing groove 62.
According to the invention, since two sides of the groove 1 are provided with nail passing accommodation grooves 31, 32, the nail-box unit can adapt to F-shaped and T-shaped nails respectively, and can also adapt to T-shaped nails or F-shaped nails both having two different wire diameters, therefore, the range of application is widened. And meanwhile, the inner sidewalls of the accommodation grooves 31, 32 are provided with a plurality of protrusions 33 which can adapt to F-shaped and T-shaped nails with different heights.
The description above for the embodiments of the invention, aiming at giving a better understanding of the invention only, should not be considered to be limitation to the invention. Various changes and equivalents thereof without departing from the spirit and the scope of the invention, made by the skilled in the related arts, fall into the protection scope of the invention.
