The first connecting bolt 23 passes through the first connecting hole 221 and is threadedly connected to the first mounting hole 2121, thereby achieving a fixed connection between the mounting plate 22 and the fixing part 211. The hemming device body 32 is attached to the adjusting plate 31, so that the second connecting hole 321 is aligned with the second mounting hole 312. The second connecting bolt 33 passes through the second connecting hole 321 and is threadedly connected to the second mounting hole 312, thereby achieving a fixed connection between the hemming device body 32 and the adjusting plate 31. The second mounting groove 311 is aligned with the second fixing hole 222. Two second fixing bolts 5 pass through the second mounting groove 311 and are threadedly connected to the corresponding second fixing hole 222, thereby achieving a fixed connection between the hemming device assembly 3 and the mounting base 2.

[0034] Two first fixing bolts 4 pass through corresponding first mounting slots 2111 and are threaded into first fixing holes 11. The mounting base 2 can be slid vertically as needed to adjust the relative vertical position of the hemming machine body 32. Tightening the first fixing bolts 4 secures the mounting base 2 and the hemming machine assembly 3 to the machine body 1. The second connecting bolt 33 and the second fixing bolt 5 can be loosened as needed to adjust the relative horizontal position of the hemming machine body 32.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
