Simultaneously, the first positioning pin 9 on the first fixing frame 7 engages with the workpiece hole to achieve vertical positioning. The second fixing frame 11 of the second positioning assembly further reinforces the positioning through the second positioning pin 12. The other end of the workpiece is positioned from the inside by the limiting pin 17 and its first positioning head 1701 on the top of the third mounting frame 16. At the same time, the second positioning head 22 is clamped from the outside by rotating the third threaded rod 21.
