[0040] By adopting the cooperation of the movable block 141 and the movable groove 13, and the T-shaped movable groove 13 prevents the movable block 141 from being separated from the movable groove 13, the movable groove 13 limits and guides the movable block 141 and the wiping plate 145, the rotating seat 12 can control the movable block 141 and the wiping plate 145 to rotate through the movable groove 13, and the wiping plate 145 can move away from or close to the movable rod 4 along the movable groove 13, the elastic force of the first elastic component 142 acts on the movable block 141 to prevent the movable block 141 from moving randomly, and after the extension rod 144 loses external extrusion, the wiping plate 145 is controlled to reset to ensure that the wiping plate 145 is in stable contact with the movable rod 4.

The position of the push seat 159 corresponds to the position of the extension rod 144, and the rotation trajectory of the tip of the push seat 159 is greater than the rotation trajectory of the extension rod 144 closest to the movable rod 4.

[0053] The inner gear ring 152 is limitedly supported by the second bearing 154, so that the inner gear ring 152 can stably rotate and stably contact with the rotating transmission assembly 155, and the inclined portion of the push seat 159 can squeeze and support the extension rod 144, so that the extension rod 144 and the wiping plate 145 move away from the movable rod 4;

[0055] The third bearing 1552 is used to limit the gear 1551, so as to ensure that the gear 1551 rotates smoothly between the inner gear ring 152 and the outer gear ring 151, and does not revolve around the inner gear ring 152, so as to smoothly realize the transmission of the rotation between the inner gear ring 152 and the outer gear ring 151;

[0056] Preferably, the movable rotating device 16 includes a connecting seat 161 rotatably arranged outside the cylinder body 1, and a guide bead 163 is fixedly connected to the inner arc surface of the connecting seat 161. The guide bead 163 is slidably connected in the guide groove 10. The guide bead 163 is set to be hemispherical, and three guide sleeves 162 are connected through the side of the connecting seat 161, and a guide rod 164 is slidably connected in the guide sleeve 162.

[0057] Preferably, the left end of the guide rod 164 is fixedly connected to the rotating seat 12, the right end of the guide rod 164 is fixedly connected to the limiting ring 165, a fourth bearing 166 is provided in the limiting ring 165, the fourth bearing 166 is sleeved on the outside of the cylinder body 1, and a second elastic component 167 is provided on the outer sleeve of the guide rod 164, the left end of the second elastic component 167 is fixedly connected to the rotating seat 12, and the other end of the second elastic component 167 is fixedly connected to the connecting seat 161, the left limit position of the movement of the piston 2 is located on the right side of the left end of the guide groove 10, and the left side of the piston 2 and the right side of the connecting seat 161 have the same magnetism.

[0058] Working principle: when the liquid on the right side of the cylinder body 1 is sucked out through the injection pipe 8, the movable rod 4 contracts and enters the cylinder body 1. When the piston 2 moves to the right, the magnetic force between the piston 2 and the connecting seat 161 decreases. At this time, the elastic force of the second elastic component 167 on the connecting seat 161 controls the connecting seat 161 to move to the right. The guide bead 163 is restricted and guided by the guide groove 10 to control the connecting seat 161 and the limit ring 165 to rotate. During the rotation of the connecting seat 161, the guide rod 164 controls the rotation of the rotating seat 12. During the rotation of the rotating seat 12, the movable block 141, the extension rod 144 and the wiping plate 145 are driven to rotate through the movable groove 13.

[0059] During the rotation of the wiping plate 145, the surface of the movable rod 4 moving into the cylinder body 1 is wiped and cleaned, so that the particles adhering to the surface of the movable rod 4 are cleaned. During the rotation of the rotating seat 12, the outer gear ring 151 is controlled to rotate by the first cross bar 153. During the rotation of the outer gear ring 151, the gear 1551 is controlled to rotate. During the rotation of the gear 1551, the inner gear ring 152, the second cross bar 156 and the rotating ring 157 are controlled to rotate by meshing. When the rotating ring 157 rotates, the push seat 159 is controlled to rotate. The gear 1551 is used for transmission, so that the push seat 159 and the rotating seat 12 are controlled to rotate in different directions and speeds. During the rotation of the extension rod 144, the inclined part of the push seat 159 is contacted.

[0060] Since the extension rod 144 is fixed to the rotating seat 12, when the extension rod 144 rotates relative to the pushing seat 159, the inclined part of the pushing seat 159 squeezes the extension rod 144 and the movable block 141 to move away from the movable rod 4, so that the wiping plate 145 is separated from the movable rod 4. After the extension rod 144 passes over the pushing seat 159, the movable block 141 is quickly reset by the elastic force of the first elastic component 142, and the wiping plate 145 quickly contacts with the movable rod 4, so that the wiping plate 145 is separated from the movable rod 4 and contacts again. The particles adhered to the surface of the wiping plate 145 can be cleaned and dropped, and the pushing seat 159 can lift the wiping plate 145 at different positions on the side of the movable rod 4.
