Two limiting plates 12 are symmetrically fixedly connected to the handle 5, and two limiting slots 13 are symmetrically opened on the mounting bracket 2, with the two limiting plates 12 respectively engaging into the two limiting slots 13.

[0026] In the above embodiment, during assembly, the two limiting plates 12 on the handle 5 are inserted into the two limiting slots 13 on the mounting bracket 2. The handle 5 is pushed so that the insert 9 on the mounting bracket 2 is inserted into the mounting groove 8, aligning the two screw holes 10. The locking wing bolt 11 is screwed into the screw hole 10 on the mounting block 7. The sealing connection nut 4 is turned to connect the air inlet pipe 6 and the air guide pipe 3, completing the rapid assembly of the riveting device. The handle 5 can be connected to the air supply equipment for skin repair riveting work. After use, the locking wing bolt 11 is turned to disengage from the mounting block 7. The sealing connection nut 4 is turned to separate the air guide pipe 3 from the air inlet pipe 6. The handle 5 can be pulled to separate the handle 5 from the riveting machine body 1, thus enabling the riveting device to be quickly disassembled into two independent parts. Its L-shaped structure can be changed, thereby reducing the space occupied by the riveting device when carrying it. It can also be carried separately, effectively improving the portability of the riveting device.

[0027] A U-shaped plate 14 is fixedly connected to the lower side of the riveting machine body 1. A rotating plate 15 is rotatably connected inside the U-shaped plate 14. A locking bolt 16 is threadedly connected between the U-shaped plate 14 and the rotating plate 15. An auxiliary handle 17 is fixedly connected to the rotating plate 15.

[0028] In this embodiment, during use, loosen the locking bolt 16 to release the fixing of the locking bolt 16 to the rotating plate 15, move the auxiliary handle 17 so that the auxiliary handle 17 is perpendicular to the riveting machine body 1, and then tighten the locking bolt 16. When riveting, hold the handle 5 with one hand and the auxiliary handle 17 with the other hand, which can more stably control the riveting device to perform skin repair riveting work, effectively improving the stability and comfort of using the riveting device. After use, the auxiliary handle 17 can be folded under the riveting machine body 1 to reduce the space occupied.

[0029] A first L-shaped buckle plate 18 is fixedly connected to the riveting machine body 1, and a second L-shaped buckle plate 19 is fixedly connected to the handle 5.

[0034] The outer wall of the anti-slip sleeve 22 is evenly provided with multiple anti-slip grooves 25. The anti-slip sleeve 22 is made of rubber, which can improve the anti-slip effect when gripping the anti-slip sleeve 22.

[0035] Working principle: During assembly, insert the two limiting plates 12 on the handle 5 into the two limiting slots 13 on the mounting bracket 2, push the handle 5 to make the insert block 9 on the mounting bracket 2 snap into the mounting groove 8, align the two screw holes 10, screw the locking wing bolt 11 into the screw hole 10 on the mounting block 7, and tighten the sealing connection nut 4 to connect the air inlet pipe 6 and the air guide pipe 3, completing the quick assembly of the riveting device. Connect the handle 5 to the air supply equipment. During riveting, loosen the locking bolt 16 to release the locking bolt 16 from fixing the rotating plate 15, and move the auxiliary handle 17 so that the auxiliary handle 17 is perpendicular to the riveting machine body 1. After tightening the locking bolt 16, hold the handle 5 with one hand and the auxiliary handle 17 with the other hand during riveting. Rivet by pressing the switch on the handle 5. After use, tighten the locking butterfly bolt 11 to disengage it from the mounting block 7. Tighten the sealing connection nut 4 to separate the air guide pipe 3 from the air inlet pipe 6.
