[0067] In use, the bearing plate 62 is buckled on the wiping and cleaning device, the second standard positioning end face is in contact with the second cleaning block 6441, the first standard positioning end face is in contact with the first cleaning block 6431, and a downward pressure is applied to the bearing plate 62, the downward pressure applied to the bearing plate 62 is transmitted to the driving sleeve 641 through the second wiping and cleaning assembly 644 and the mounting base 642, the driving sleeve 641 rotates and slides downward along the axis of the base 6321 under the action of the downward pressure, the driving sleeve 641 rotates and drives the mounting base 642 to rotate, so as to drive the first wiping and cleaning assembly 643 and the second wiping and cleaning assembly 644 to rotate, thereby realizing the control of the first cleaning block 6431 wiping the first standard positioning end face and the second cleaning block 6441 wiping the second standard positioning end face.

[0068] Meanwhile, since the first standard positioning end face is in contact with the first cleaning block 6431, the downward sliding of the first wiping and cleaning component 643 is restricted, thereby allowing the first wiping and cleaning component 643 and the second wiping and cleaning component 644 to move relative to each other in the vertical direction. This, in turn, drives the cooperating link 645 to rotate. The rotation of the cooperating link 645 controls the first cleaning block 6431 and the second cleaning block 6441 to move synchronously along the radial direction of the drive sleeve 641. That is, before the first wiping and cleaning component 643 and the second wiping and cleaning component 644 contact, the first cleaning block 6431 is controlled to exit the first standard positioning end face, and the second cleaning block 6441 is controlled to exit the second standard positioning end face, so as to avoid interference between the second standard positioning end face and the first standard positioning end face.

[0069] When the first wiping and cleaning component 643 and the second wiping and cleaning component 644 come into contact, the base 6321, drive sleeve 641, mounting base 642, first wiping and cleaning component 643, second wiping and cleaning component 644 and cooperating link 645 will be locked, forming a rigid connection. To prevent this rigid connection from obstructing the contact between the second standard positioning end face and the first standard positioning end face, under the continuous action of downward pressure, the mounting base 642 slides into the limiting groove 6411 to achieve a retraction action, thereby enabling the second standard positioning end face to contact the first standard positioning end face and achieve precise positioning.

At the same time, the mounting plate 6421 can slide up and down in the limiting groove 6411, so that when the first wiping and cleaning component 643 and the second wiping and cleaning component 644 come into contact, the mounting plate 6421 slides into the limiting groove 6411 to achieve a retraction action, ensuring that the second standard positioning end face can contact the first standard positioning end face to achieve precise positioning.
