The two ends of the V-shaped pressure rods 3 are slidably connected with the through grooves 5 inside the bottom of the V-shaped bearing plate 2. As the V-shaped pressure rods 3 gradually descend, they come into contact with the outer wall of the pin shaft and gradually exert pressure on the pin shaft until the pin shaft is stably clamped and positioned on the top of the V-shaped bearing plate 2. During this process, the V-shaped opening design of the V-shaped bearing plate 2 and the V-shaped pressure rods 3 can well adapt to the shape of the pin shaft, ensuring the stability and accuracy of clamping.
