[0035] Example:

[0036] like Figures 2 to 7 As shown, this embodiment discloses a hook-punch wedge. The hook-punch wedge includes a base assembly 100, a slider assembly 200 and a drive assembly 300.

[0037] The base assembly 100 includes a base 110, a spring top block 120, a base guide plate 130, a pressure plate 140, a stop block 150, and a buffer 160; the spring top block 120 is installed at the front end of the base 110, the base guide plate 130 is installed on the top surface of the base 110, the pressure plate 140 is installed on the side of the base 110, the stop block 150 is installed at the rear end of the base 110, and the buffer 160 is installed in the stop block 150 to cushion the slider 210 when it retracts. The base guide plate 130 is fixed to the base 110 by screws, and the pressure plate 140 is fixed to the end surfaces of both sides of the base 110 by screws. The base guide plate 130, the two inner side surfaces of the base 110 and the pressure plate 140 form a slide groove, and the open end of the slide groove is detachably provided with a stop block 150, and the closed end of the slide groove is detachably provided with a spring top block 120; the top surface of the slider assembly 200 is in sliding contact with the base guide plate 130, and the side surface of the slider assembly 200 is in sliding contact with the two inner side surfaces of the base 110 and the pressure plate 140. The buffer 160 is installed on the stop block 150 to buffer the retracting slider 210.

[0038] The slider assembly 200 includes a slider 210, a spring 220, a forced returner 230, a slider guide 240, a mounting surface 250, and a slider side guide 260; the spring 220 provides a retraction force for the slider 210; the forced returner 230 is mounted on both sides of the slider 210; the slider guide 240 and the driving block 310 are guided by the convex V-shaped guide 320 and the slider guide 240, the mounting surface 250 is fixed to the slider by screws and positioning pins, and the slider side guide 260 is mounted on both sides of the slider 210 ; The spring 220 is installed on the slider 210, and the slider guide 240 is fixed to the slider 210 by screws; the slider side guide 260 is fixed to the two side surfaces of the slider 210 by screws, and the mounting surface 250 is fixed to the slider 210 by screws and positioning pins, and can be disassembled and replaced independently; the forced returner 230 is fixed to the two side surfaces of the slider 210 by screws.
