The limiting component includes a round rod 63, and a handwheel 64 is fixedly connected to the front surface of the round rod 63. The handwheel 64 is easy to grip. The inner wall of the moving block 53 is elastically connected to the limiting block 62 through the connecting spring 61. The front surface of the nail plate 4 is provided with a limiting groove 601. The limiting block 62 and the limiting groove 601 fit together. There are two sets of positioning components and limiting components, which are symmetrically distributed front and back with respect to the center line of the nail magazine 1.

[0034] Reference Figure 1 - Figure 3 The protective assembly includes a cover plate 31, the lower surface of which is attached to the upper surface of the nail plate 4. A plug 32 is fixedly connected to the lower surface of the cover plate 31, and a rubber ring 33 is fixedly connected to the bottom end of the outer wall of the plug 32. The rubber ring 33 will deform when squeezed. A buckle groove 303 is provided on the right surface of the cover plate 31, into which a finger can be inserted to facilitate pulling the cover plate 31 upward. A slot 301 is provided on the upper surface of the nail plate 4, which is slightly larger than the plug 32. An annular groove 302 is provided on the inner wall of the nail plate 4, and the rubber ring 33 fits into the annular groove 302.

[0035] Reference Figure 2 , Figure 4 , Figure 5 The positioning block 51 is slidably connected to the upper surface of the staple cartridge 1 and slides longitudinally.

One end of the connecting spring 61 is fixedly connected to the front surface of the limiting block 62, and the other end of the connecting spring 61 is fixedly connected to the inner wall of the front side of the moving block 53. When the limiting block 62 moves forward, it will squeeze the connecting spring 61 to generate a reaction force. The limiting block 62 is slidably connected to the rear surface of the moving block 53 and the rear surface of the staple cartridge 1. The limiting block 62 is inserted into the inner wall of the limiting groove 601 and can limit the staple plate 4.

[0036] Reference Figure 1 - Figure 3The slot 301 and the annular groove 302 are communicated, the plug 32 is inserted into the inner wall of the slot 301, and the rubber ring 33 is inserted into the inner wall of the annular groove 302, so that the cover plate 31 can be preliminarily fixed.

[0037] Working principle: when the device is used, the cover plate 31 is removed first, so that the nail plate 4 can be normally used; when the cover plate 31 is removed, the buckle slot 303 is buckled by one hand, the other hand is pressed against the nail plate 4, and the other end of the cover plate 31 is moved upward, then the hand buckling the buckle slot 303 is moved upward, at this time, external force is applied to the rubber ring 33, the rubber ring 33 is extruded and deformed, and the annular groove 302 is separated from the annular groove 302 and enters the slot 301, then the cover plate 31 is moved upward until the plug 32 and the slot 301 are separated, and the cover plate 31 is removed.

[0038] Then, the nail plate 4 is aligned with the nail magazine 1 and is inserted, the positioning block 51 is extruded when the nail plate 4 moves downward, so that the positioning block 51 moves downward, the positioning block 51 moves downward and extrudes the compression spring 52 to generate a reaction force and drives the inclined groove 501 to move downward, the inclined groove 501 moves downward and extrudes the sliding block 54, and then drives the moving block 53, the connecting spring 61, the limiting block 62, the round rod 63 and the hand wheel 64 to move forward, the limiting block 62 moves forward and is pressed against the nail plate 4 due to the action force of the connecting spring 61, when the lower surface of the nail plate 4 contacts the nail magazine 1, the limiting block 62 is aligned with the limiting groove 601 and is inserted into the limiting groove 601 to limit the nail plate 4, and the installation of the nail plate 4 is completed.

[0039] After the nail plate 4 is used, the hand wheel 64 is pulled to drive the round rod 63 away from the nail plate 4, the round rod 63 moves and drives the limiting block 62 to move synchronously, the limiting block 62 moves and extrudes the connecting spring 61 to generate a reaction force and is separated from the limiting groove 601 to release the limitation of the nail plate 4, then the nail plate 4 is moved upward and taken out from the nail magazine 1.

[0040] Finally, it should be pointed out that: the above-mentioned only for preferred embodiments of the present application, and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
