Two clamping hydraulic cylinders 4-2 arranged at intervals on the left and right are respectively fixedly connected to the bottom wall of the clamping base plate, and the telescopic rods of each clamping hydraulic cylinder 4-2 arranged in the vertical direction pass through the through holes on the clamping base plate and are respectively fixedly connected to a lower clamping V-shaped block 4-3 by bolts. A clamping plate is fixed to the clamping base plates on the front and rear sides of each lower clamping V-shaped block, and a strip groove is opened on the clamping plate. A pin shaft 4-4 is fixed in the horizontal direction at the front and rear ends of the lower clamping V-shaped block 4-3, and the pin shaft 4-4 is respectively passed through the strip grooves on the clamping plates on the adjacent sides, and the pin shaft can move up and down in the strip groove.
