Through the arrangement, the contact area between the linkage part and the clamping jaw part extension section is increased, the relative rotation of the linkage part and the clamping jaw part is avoided, and the stability is ensured.
Preferably, at least the first mating hole is an internal threaded hole, among the first mating hole and the second mating hole. The contact area between the bolt and the clamping claw part is increased through the upper arrangement, so that the fixing effect between the clamping claw part and the linkage part can be improved.
Preferably, the width of the clamping jaw part is larger than that of the extension section, and when the extension section is fixed with the front section of the linkage part, the front end surface of the linkage part is contacted with the rear end surface of the clamping jaw part. When the clamping jaw part is stressed and has a trend force moving relative to the linkage part, the front end surface of the linkage part and the rear end surface of the clamping jaw part can also prop against each other to disperse the stress so as to further reduce the stress at the bolt.
The utility model is characterized in that the main stress part is a limit bulge part rather than a bolt connection part when in work, thereby having the advantages of solving the defect of frequent fracture of bolts, avoiding fracture between the clamping claw part and the linkage part, preventing the workpiece from being separated, enabling the roll forging machine to be used in a normal reciprocating way and improving the automatic operation efficiency of the equipment.
