[0056] In use, the zero point supporting plate 62 is buckled on the wiping cleaning device, the second zero point end face is in contact with the second wiping block 6441, the first zero point end face is in contact with the first wiping block 6431, and a downward pressure is applied to the zero point supporting plate 62, the downward pressure applied to the zero point supporting plate 62 is transmitted to the rotating sleeve 641 through the second wiping assembly 644 and the mounting rack 642, the rotating sleeve 641 rotates and slides downward along the axis of the positioning seat 6321 under the action of the downward pressure, the rotating sleeve 641 rotates and drives the mounting rack 642 to rotate, so as to drive the first wiping assembly 643 and the second wiping assembly 644 to rotate, and then the first wiping block 6431 is controlled to wipe the first zero point end face and the second wiping block 6441 is controlled to wipe the second zero point end face.

[0057] Meanwhile, since the first zero-point end face is in contact with the first sweeping block 6431, the downward sliding of the first sweeping assembly 643 is restricted, thereby allowing the first sweeping assembly 643 and the second sweeping assembly 644 to move relative to each other in the vertical direction, which in turn drives the coordinating rod 645 to rotate. The rotation of the coordinating rod 645 controls the first sweeping block 6431 and the second sweeping block 6441 to move synchronously along the radial direction of the rotating sleeve 641. That is, before the first sweeping assembly 643 and the second sweeping assembly 644 contact, the first sweeping block 6431 is controlled to exit the first zero-point end face, and the second sweeping block 6441 is controlled to exit the second zero-point end face, so as to avoid interference between the second zero-point end face and the first zero-point end face.

In order to prevent this rigidly connected whole from obstructing the contact between the second zero-point end face and the first zero-point end face, at this time, under the continuous action of the downward pressure, the mounting frame 642 slides into the limiting groove 6411 to realize the retraction action, so that the second zero-point end face can contact the first zero-point end face and achieve precise positioning.

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

[0061] Preferably, such as Figure 6 As shown, the mounting frame 642 includes a support plate 6421, which is installed in a limiting groove 6411 to restrict the relative rotation of the mounting frame 642 and the rotating sleeve 641, so that the mounting frame 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 come into contact, the support plate 6421 slides into the limiting groove 6411 to achieve a retraction action, ensuring that the second zero-point end face can contact the first zero-point end face and achieve precise positioning.

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

When the downward pressure applied to the mounting frame 642 is removed, the support plate 6421 can be controlled to automatically return to the initial position, so that the first sweeping block 6431 can contact the first zero-point end face.

[0063] Preferably, the support plate 6421 is provided with a limiting groove 6423, which extends in the vertical direction.

[0064] Preferably, such as Figure 7 As shown, the first sweeping assembly 643 further includes a first ring support 6432 and a first cooperating ring 6433. Both the first sweeping block 6431 and the first cooperating ring 6433 are mounted on the first ring support 6432. The first sweeping block 6431 can slide radially along the first ring support 6432, and the first cooperating ring 6433 can rotate circumferentially on the first ring support 6432. The first cooperating ring 6433 is also connected to the first sweeping block 6431. Rotating the first cooperating ring 6433 controls the first sweeping block 6431 to slide radially along the first ring support 6432. The first ring support 6432 is sleeved on the support plate 6421, and is supported by... The support plate 6421 can restrict the rotation of the first ring support 6432 relative to the mounting frame 642, so that the first ring support 6432 can rotate synchronously with the mounting frame 642. The first ring support 6432 can also slide up and down on the support plate 6421, so that the first sweeping block 6431 keeps in contact with the first zero-point end face, thereby realizing the rotation of the first sweeping block 6431 to wipe the first zero-point end face.
