The drive mechanism is connected to the punching mechanism through a linkage mechanism. It also includes a horizontal limiting mechanism for horizontal sliding to position the eyelet, and a height limiting mechanism for vertical sliding to adjust the height between the horizontal limiting mechanism and the punching plate 3.

[0019] The stamping mechanism includes a stamping rod 4 and a punch pin 5. A drive mechanism is connected to the stamping rod 4 via a linkage mechanism. The punch pin 5 is detachably mounted on the bottom of the stamping rod 4. The end of the stamping rod 4 connected to the punch pin 5 has a threaded groove, and the end of the punch pin 5 connected to the stamping rod 4 has a connecting end with external threads. The stamping rod 4 is threadedly connected to the connecting end of the punch pin 5 through the threaded groove, and the inner diameter of the threaded groove matches the outer diameter of the connecting end. The connecting end is a cylindrical connecting rod.

[0020] like Figure 2 As shown, the height limiting mechanism includes a sliding plate 6, a fixing block 7, a sliding rod 8, and a first locking bolt 9. The sliding plate 6 is vertically arranged, and both ends of the sliding plate 6 are fixed to the side of the end of the frame 2 connected to the base 1 by the fixing block 7. The sliding rod 8 is horizontally arranged, and one end of the sliding rod 8 is slidably sleeved on the sliding plate 6. A threaded hole is opened on the end of the sliding rod 8 that is slidably connected to the sliding plate 6. The first locking bolt 9 fixes the sliding rod 8 to the sliding plate 6 by threading it into the threaded hole. The end of the sliding rod 8 away from the sliding plate 6 is connected to the horizontal limiting mechanism.

[0021] The horizontal limiting mechanism includes a first limiting piece 10, a first positioning piece 11, and a second locking bolt 12. Both the first limiting piece 10 and the first positioning piece 11 are arranged laterally.

[0022] The base 1 has a cavity inside, and an opening communicating with the cavity is opened on one side of the base 1. A drawer 13 is slidably installed inside the cavity through the opening. The drawer 13 is divided into several compartments by partitions.

[0023] The usage process in this embodiment is as follows: During operation, slide the slide rod 8 up and down to adjust the relative position of the slide rod 8 and the slide plate 6, thereby adjusting the height of the first limiting plate 10 and the first positioning plate 11 so that the distance between the first positioning plate 11 and the stamping plate 3 is suitable for the thickness of the shoe upper.

The third locking bolt 16 passes through the second limiting groove and the through hole and is threadedly connected to the nut 17. The other end of the second positioning plate 15 extends above the stamping plate 3 and has an arc-shaped surface adapted to the punch assembly. The inner arc surface of the arc-shaped surface faces the stamping plate 3.

[0026] In this embodiment, the slide bar 8 is fixed to the corresponding position of the slide plate 6, and the distance between the second positioning plate 15 and the stamping plate 3 is suitable for the thickness of the shoe upper. When the second positioning plate 15 is moved horizontally, the arc surface on the second positioning plate 15 is moved to a suitable position. Then, the third locking bolt 16 passes through the second limiting slide groove and through the through hole and is threadedly connected to the nut 17 to fix the second positioning plate 15 on the second limiting plate 14.
