The drill rod and the cylinder are mainly fixed and limited by the cooperation of the drill rod pin. During the processing of the existing drill rod pin, it is necessary to use a punching device to punch the drill rod pin, and during the punching process, a clamp is needed to fix and limit the drill rod pin to facilitate punching of the drill rod pin surface.

During the clamping process, the contact surface between the clamping block and the drill rod pin is small, and the drill rod pin needs to withstand a strong impact force during the punching process, which will make the drill rod pin easy to slide and dislocate during the punching process, thereby reducing the stability of the punching equipment.

[0079] In the present scheme, multiple groups of positioning arc blocks 19 with different inner wall diameters are provided, and sliding blocks 20 of the same size are welded on the positioning arc blocks 19. When it is necessary to fix threaded drill rods of different sizes, the support block 16 is first pulled out so that the support block 16 drives the positioning rod 15 to move out of the sliding groove 18. At this time, the support block 16 stretches the support spring 17 so that the support spring 17 is stretched and deformed, and then the sliding block 20 of the positioning arc block 19 with a suitable inner wall diameter is slid into the sliding groove 18.

When threaded drill rods of different sizes need to be fixed, the support block 16 is first pulled out so that the support block 16 drives the positioning rod 15 to move out of the sliding groove 18. At this time, the support block 16 stretches the support spring 17 so that the support spring 17 is stretched and deformed, and then the sliding block 20 of the positioning arc block 19 with a suitable inner wall diameter is slid into the sliding groove 18.
