The positioning pin 12 can limit the movement of the shaft end part 6 along the first direction A. The first pressing block assembly 3 can further fix the position of the shaft end part 6 to prevent the shaft end part 6 from shifting during the processing. The structure is simple and easy to install, which is conducive to fixing the position of the shaft end part 6 and facilitating the subsequent processing of the shaft end part 6.

[0036] During installation, the shaft end part 6 is placed on the base 1, and the positioning bar 2 is inserted into the through groove 61 of the shaft end part 6, the lower end of the first screw rod 33 is fixedly connected to the base 1, the first support block 31 is placed on the base 1, the first pressure block 32 is sleeved on the upper end of the first screw rod 33, and the first pressure block 32 is rotated so that one end of the first pressure block 32 presses the first support block 31 and the other end presses the upper end surface of the shaft end part 6, and the first nut 34 is sleeved and rotated, and the first pressure block 32 is pressed, and the installation is completed. The first screw rod 33 and the first nut 34 are conducive to adjusting the height of the first pressure block 32, so that the first pressure block 32 can press the upper end surface of the shaft end part 6. The positioning bar 2, the positioning pin 12 and the first pressure block assembly 3 together keep the position of the shaft end part 6 fixed.

[0037] Furthermore, the positioning groove 11 is provided with an assembly hole, and the positioning strip 2 is provided with a mounting through hole.
