[0003] The patent with announcement number CN217701218U discloses "a mold for assembling a pin shaft and a chain plate, including a bearing seat, with vertical plates fixed at both ends of the top of the bearing seat, and a top plate installed between the two groups of vertical plates. The present application arranges the fixing plate, the screw rod, the turntable and the clamping plate in coordination, so that the screw rod can be driven to rotate by rotating the turntable, thereby driving the clamping plate to move, and facilitating the adjustment of the spacing between the two groups of clamping plates, so that the two groups of clamping plates can fix and clamp the chain plate body, and try to avoid the chain plate body from being offset during assembly, thereby improving the accuracy of the assembly of the chain plate body and the pin shaft body, and improving the quality of assembly".

[0004] With regard to the above-mentioned related technologies, the inventor believes that when replacing the pressure plate, it is necessary to first use a wrench or other tool to rotate the locking bolt and screw the locking bolt out of the screw hole, and then remove the damaged pressure plate that has been detached from the fixation from the bottom of the mounting plate. Then, it is necessary to insert another intact pressure plate into the bottom of the mounting plate and rotate the locking bolt in the opposite direction so that one end of the locking bolt can be inserted into the connecting block. Therefore, when replacing the pressure plate, it is necessary to use a wrench or other tool to rotate the bolt back and forth, and it is also necessary to temporarily store the bolt screwed out of the screw hole, otherwise the bolt may be lost, which is time-consuming and inconvenient, and therefore needs to be improved.
