When the nail bin is installed, the rear end of the nail pushing sliding block is meshed with the lower part of the front end of the blade, so that one-time firing safety is triggered, the rear end of the nail bin is clamped into the nail bin seat in the installation process, then the nail bin is slid backwards until the rear end of the nail bin is clamped with the rear end of the nail bin seat, finally the front end of the nail bin is pressed down into the nail bin seat, the risk that the nail pushing sliding block is displaced after being touched by the cutting knife exists in the process of sliding the nail bin backwards, at the moment, the nail pushing sliding block cannot be matched with the blade normally, one-time firing safety fails, the anastomat cannot be fired normally, and risks exist in the use process.
Based on the above, the utility model designs the nail bin upper cover buckle for preventing the nail pushing block from moving so as to solve the problems.
Disclosure of Invention
The utility model aims to provide a nail bin upper cover buckle for preventing a nail pushing block from being displaced, so as to solve the problem that the prior art has disadvantages in the prior art.
In order to achieve the above purpose, the present utility model provides the following technical solutions: nail bin upper cover buckle of preventing pushing away nail piece displacement, including buckle body, nail bin and nail bin seat, its characterized in that: the nail bin is arranged in the nail bin seat in a clamping manner, the clamping buckle body is arranged on the upper surface of the nail bin in a clamping manner and used for protecting the nail bin, a blade groove is formed in the middle of the upper surface of the nail bin, a nail pushing sliding block is transversely and slidably arranged in the blade groove, a raised strip is fixedly arranged on the lower surface of the clamping buckle body and positioned in the blade groove, a protruding block for limiting the nail pushing sliding block is fixedly arranged at the right end of the raised strip, and a blade is arranged at the right end of the nail bin seat;
as a further scheme of the utility model, the distance from the right end of the lug to the blade is just equal to the left and right length of the nail pushing block;
as a further scheme of the utility model, the upper side and the lower side of the right end of the lug are subjected to rounding treatment;
as a further scheme of the utility model, a plurality of hollow grooves are formed on the surface of the convex strip;
as a further scheme of the utility model, the left end of the buckle body is fixedly provided with an operation strip.
Compared with the prior art, the utility model has the beneficial effects that:
this device is through fixed the setting lug in the sand grip right side of buckle body below, when buckle body detained in the nail storehouse top, the lug right-hand member can just with push away the left end contact of nail slider, the lug can push away the left end of nail slider all the time, push away the nail slider just can not take place the displacement because of contacting with the blade like this, ensure to push away the nail slider can be smooth with the blade cooperation, prevent to push away the nail slider and appear the displacement when cooperating with the blade, ensure that the blade can fire smoothly, eliminate the risk that the blade can't fire at the operation in-process.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-4, the present utility model provides a technical solution: nail bin upper cover buckle of preventing pushing away nail piece displacement, including buckle body 1, nail bin 2 and nail bin seat 3, its characterized in that: the nail bin 2 is arranged in the nail bin seat 3 in a clamping way, the clamping buckle body 1 is arranged on the upper surface of the nail bin 2 in a clamping way and used for protecting the nail bin 2, the middle of the upper surface of the nail bin 2 is provided with the blade groove 4, the nail pushing sliding block 5 is transversely and slidably arranged in the blade groove 4, the lower surface of the clamping buckle body 1 is fixedly provided with the convex strip 6, the convex strip 6 is positioned in the blade groove 4, the right end of the convex strip 6 is fixedly provided with the convex block 7 used for limiting the nail pushing sliding block 5, and the right end of the nail bin seat is provided with the blade;
when the nail box is used, after the nail box 2 is required to be installed on the nail box seat 3, the clamping buckle body 1 clamped on the upper surface of the nail box 2 is separated from the nail box 2, when the nail box 2 is installed on the nail box seat 3, when the nail box 2 is installed in the nail box seat 3 from the left end of the nail box seat 3 to the right, the protruding block 7 on the right side of the protruding strip 6 below the clamping buckle body 1 can always support the left end of the nail pushing sliding block 5, so that the nail pushing sliding block 5 cannot displace due to contact with a blade, smooth cooperation with the blade is ensured, smooth firing of the blade is ensured, and the risk that the blade cannot fire in the operation process is eliminated.
