The downward pressure applied to the zero-point support plate 62 is transmitted to the rotating sleeve 641 through the second sweeping assembly 644 and the mounting stand 642. Under the action of the downward pressure, the rotating sleeve 641 rotates and slides downward along the axis of the positioning seat 6321.

[0059] Preferably, a first sliding groove is further provided on the outer circumference of the positioning seat 6321, and the first sliding groove is spirally arranged.

[0060] Preferably, the rotating sleeve 641 is also provided with a first protruding block 6412, which is arranged on the inner wall of the rotating sleeve 641 and can be inserted into the first sliding groove and slide along the first sliding groove, so that the rotating sleeve 641 can rotate along the axis of the positioning seat 6321 and slide up and down when the rotating sleeve 641 is acted upon by external force.

[0061] Preferably, if Figure 6 As shown, the mounting bracket 642 includes a support plate 6421, and the support plate 6421 is installed in the limiting groove 6411 to limit the relative rotation of the mounting bracket 642 and the rotating sleeve 641, so that the mounting bracket 642 can rotate synchronously with the rotating sleeve 641; at the same time, the support plate 6421 can slide up and down in the limiting groove 6411, so that when the first sweeping component 643 and the second sweeping component 644 are in contact, the support plate 6421 slides into the limiting groove 6411 to achieve a retreat action, thereby ensuring that the second zero point end face can contact the first zero point end face to achieve precise positioning.

[0062] Preferably, the mounting bracket 642 also includes a second spring 6422, one end of the second spring 6422 is fixedly connected to the support plate 6421, and the other end is fixedly installed in the limiting groove 6411.
