Detailed Description

(example 1)

Referring to fig. 1 and 2, the anti-misoperation stapler excitation assembly of the embodiment includes a lower holder 1, a locking block 2, a slide block 3, a push block 4 and a staple pushing frame.

The lower clamping seat 1 is provided with a through groove 1-1 penetrating through two ends of the lower clamping seat. The locking block 2 is fixed in the tail end of the through groove 1-1. The sliding block 3 is in sliding fit in the through groove 1-1. The push block 4 is movably arranged on the lower clamping seat 1 and is fixedly connected with the sliding block 3. The push pin is erected in the through groove 1-1 and is detachably connected with the sliding block 3. When the sliding block 3 is contacted with the locking block 2, the locking block 2 positions the sliding block 3 in the through groove 1-1.

The lower clamping seat 1 is an integrally formed U-shaped frame, and is easy to form and process. The through groove 1-1 is formed by two side walls of the U-shaped frame. Mounting through holes 1-2 are correspondingly arranged on the two side walls of the tail end of the U-shaped frame. The locking block 2 is matched and fixed at the tail end of the through groove 1-1 through the pin shaft 6 and the two mounting through holes 1-2, and the fixing is more convenient.
