DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] like Figure 1 The zipper translation push mechanism for zipper detection shown in the figure comprises a fixed seat 1, a pulling device 2 and a pushing device 3; the fixed seat 1 has a zipper slide 11; the pulling device 2 comprises a pulling claw 21 and a translation module 22; Figure 2-4 As shown, the pushing device 3 includes a sliding seat 31 and a telescopic execution unit 33; a claw 34 is rotatably mounted on the sliding seat 31, and the claw 34 switches between an active state and an idle state. In the active state, the claw 34 acts on the square piece of the zipper. In this embodiment, the claw 34 includes an arc portion 34a and a sending portion 34b; in the idle state, the arc portion 34a faces the zipper slide 11; in the active state, the sending portion 34b faces the zipper slide 11.

[0025] The telescopic execution unit 33 can make the sliding seat 31 translate relative to the fixed seat 1. The fixed block 32 has a notch 32a, and the sliding seat 31 has an insertion portion 31b that can move in the notch 32a. In this way, the sliding seat 31 can slide stably relative to the fixed seat 1. In this embodiment, the telescopic execution unit 33 is a cylinder, and its cylinder seat is fixed on the fixed seat 1.

[0026] like Figure 5 As shown, the telescopic execution unit 33 is connected to the rack 35, and the claw 34 is connected to the gear 36 meshing with the rack 35; a sliding cavity 31a is formed in the sliding seat 31; the rack 35 is slidably installed in the sliding cavity 31a; the pushing device 3 also includes a fixed block 32, and a spring 37 is arranged between the sliding seat 31 and the fixed block 32.
