[0036] When the splint 410 is under pressure, it drives the screw 420 to slide in the sliding hole 340, and the spring 430 is deformed under pressure to elastically support the splint 410 to avoid damage to the items due to rigid contact.

[0037] In order to improve the clamping stability, anti-skid pads are provided on both sides of the clamping plate 410, and anti-skid ridges are provided on the anti-skid pads to improve the anti-skid effect and avoid slipping during clamping.

[0038] Since there are potential safety hazards on the edges, the clamping jaw 320 adopts an L-shaped block, and protective rubber sleeves are provided on the external corners of the clamping jaw 320 to provide safety protection and avoid injuries to goods and personnel.

[0039] During specific use, the driving component 140 drives the driving gear 130 to rotate, the driving gear 130 drives the transmission gear 120 to rotate, the transmission gear 120 drives the driving rocker arm 150 to swing, the driving rocker arm 150 drives the clamping rocker arm 160 to move, and when the clamping rocker arm 160 moves, the rack 200 drives the jaw component 300 to open and close the clamp, and when the splint 410 is pressurized, it drives the screw 420 to slide in the sliding hole 340, and the spring 430 is deformed under pressure to elastically support the splint 410 to avoid damage to the items caused by rigid contact. When the jaw component 300 is worn, the tightening bolt 330 can be loosened and the jaw component 300 can be slid off the rack 200 for disassembly, which is convenient for quick disassembly and replacement of the jaw component 300.
