The function of the side surface of the cleaning cotton 410 being located to the left of the brush 48 is to clean again after the brush 48 has cleaned.

[0036] A specific application of this embodiment is as follows: First, when the pipetting mechanism 3 needs to be used, the medical staff first place the item to be pipetted inside the fixed groove 312 to prevent the pipetting mechanism 3 from moving during operation. Then, the motor 31 is started, and the output shaft of the motor 31 rotates counterclockwise. The counterclockwise rotation of the output shaft of the motor 31 drives the bidirectional threaded rod 32 to rotate counterclockwise. The threaded sleeve 33 threadedly connected to the bidirectional threaded rod 32 moves from right to left. The movement of the threaded sleeve 33 from right to left drives the sliding plate 35 to move from right to left through the support rod 34. During the movement of the sliding plate 35, the pipetting chamber 38 will move along the movement track inside the displacement frame 310. When the pipetting chamber 38 moves to the leftmost end of the displacement frame 310, the pipetting chamber 38 moves downward through the sliding column 37 inside the sliding groove 36. When the suction head 39 at the bottom of the pipetting chamber 38 moves inside the item in the fixed groove 312, the liquid is sucked into the pipetting chamber 38 through the extrusion rod 311. Then, due to the characteristics of the bidirectional threaded rod 32, when the pipetting chamber 38 moves to the rightmost end of the displacement frame 310, the suction head 39 of the pipetting chamber 38 moves downward to the top of the liquid storage tube 314, and then the liquid inside the pipetting chamber 38 is squeezed into the liquid storage tube 314 on the placement rack 313 through the extrusion rod 311, thereby realizing reciprocating linear pipetting.

[0037] When the workbench 1 is exposed for a long time and the pipetting mechanism 3 is used for a long time, dust and liquid will appear on the top of the workbench 1. At this time, the medical staff start the motor 31, and the output shaft of the motor 31 rotates counterclockwise. The counterclockwise rotation of the output shaft of the motor 31 drives the bidirectional threaded rod 32 to rotate counterclockwise. The gear 41 fixed to the circumferential surface of the bidirectional threaded rod 32 rotates counterclockwise. Because the gear 41 meshes with the rack 44, the counterclockwise rotation of the gear 41 drives the rack 44 to move from left to right inside the moving groove 42 through the moving column 43. The movement of the rack 44 from left to right drives the connecting rod 45 to move from left to right inside the sliding groove 46. The movement of the connecting rod 45 from left to right drives the mounting plate 47 to move from left to right. During the movement of the mounting plate 47 from left to right, the brush 48 first cleans the dust or debris on the surface of the workbench 1, and then the cleaning cotton 410 cleans the liquid on the top of the workbench 1. The debris or liquid is cleaned into the cleaning groove 49 and then slides down to the inside of the collection box 411 through the inclined surface inside the cleaning groove 49.
