Preferably, the right end of the clamping groove of the upper section of the clamping piece and the right end of the clamping groove of the lower section of the clamping piece are respectively recessed towards the inner side of the opening of the clamping piece to form a bayonet for preventing the retaining ring from slipping off.
Preferably, the left end edge of the upper section and the left end edge of the lower section of the grip piece are folded by 90 ° toward the inside of the opening of the grip piece to form folded edges.
Preferably, the left end of the clamping groove of the upper section of the clamping piece and the left end of the clamping groove of the lower section of the clamping piece are provided with splayed flaring holes for guiding the clamping pin to slide in.
The utility model has the beneficial effects that:
(1) the opening pliers can be directly used for installation and disassembly, the installation is very convenient, and the disassembly is in place in one step;
(2) the clamping sheet is used for replacing a pressure spring and a pressure spring cap, so that the number of parts is reduced, the cost is reduced, and the control is convenient;
(3) the spring force value of the existing pressure spring is 50-120N, the clamping force can reach 130N after the clamping piece is used, and the clamping force of the clamping assembly is increased.
