[0058] When it is needed to fix pot bodies of different sizes, different sizes of center positioning blocks 21 are replaced on the mounting plate 10, so that the plurality of inner riveting pieces 22 form limiting positions of different diameters, the ends of the plurality of inner riveting pieces 22 away from the center positioning block 21 can abut against the inner walls of pot bodies of different sizes, and thus the use range of the riveting clamp 1 is increased; and the ends of the inner riveting pieces 22 away from the center positioning block 21 can be installed at different positions of the oblong avoiding grooves 10a, so as to ensure the normal use of the riveting clamp 1.

[0059] The riveting clamp 1 further includes a mounting block detachably connected at the center position of the mounting plate 10, the mounting block is provided with a plurality of first screw holes, the center positioning block 21 is provided with a plurality of second screw holes, and screws are sequentially arranged in the second screw holes and the first screw holes, so that the center positioning block 21 is detachably connected with the mounting block, and the center positioning block 21 is convenient to replace.

[0060] With reference to Figures 1 to 5The mounting plate 10 is further provided with at least one mounting groove 10b, each of which is located between two adjacent avoiding grooves 10a; the mounting groove 10b has a long strip shape in the transverse section; the inner riveting mechanism 20 further comprises at least one limiting plate 23, one end of which is provided with a mounting block 23a which is detachably connected to the mounting groove 10b, and the limiting plate 23 is used for clamping in the handle of the pot.

[0065] Specifically, the inner riveting shell 221 of the inner riveting piece 22 abuts against the inner wall of the pot body to fix the position of the pot body, so that the outer riveting mechanism 3 of the riveting device can rivet and press at the riveting hole of the pot body. The first driving piece 223 drives the first transmission piece 222 to approach the transfer hole 221a, and then the first transmission piece 222 pushes the rivet located in the transfer hole 221a out, so as to push the rivet into the riveting hole of the pot body, thereby realizing automatic transfer of the rivet and lifting the riveting clamp 1. The specific structure of the first driving piece 223 and the first transmission piece 222 is not limited here, as long as the rivet can be pushed out.
