The braking pin has one step, and the lower part of the step is an inclined surface. The handle has an inner inclined surface. The nail tube is fixedly connected to the firing pin tube and is located on one side of the firing pin tube. The main sleeve is installed outside the firing pin tube. The firing pin assembly is installed in the firing pin tube. The braking pin is installed on the firing pin assembly. The braking spring is installed between the braking pin and the firing pin assembly. The handle is installed on one side of the main sleeve. The firing spring is installed between the handle and the firing pin assembly.

[0029] Figure 4 Conventional steps in the prior art.

[0030] Beneficial effects:

[0031] 1. Double-step design: The main body part of the brake pin is still a columnar structure, but two steps with different diameters are provided in its length direction. The first step is located at the head of the brake pin and cooperates with the handle inside the fastener to control the firing of the fastener. The second step is located at the tail of the brake pin, is installed in the firing pin rod hole, and is positioned in the firing pin tube chute.

[0032] 2. Structure simplification: Compared with the traditional three-step structure, the double-step design reduces one step, thus simplifying the structure and reducing the manufacturing cost. At the same time, by optimizing the size and position of the steps, the matching accuracy between the firing brake pin and other components inside the fastener is ensured, ensuring the normal operation of the integrated nail fastener; the brake pin is compressed at the inclined surface of the tail handle to complete the firing of the fastener, with a more compact structure, which can significantly shorten the length of the fastener, reduce the processing difficulty, and reduce the cost.

Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
