[0025] During the specific assembly, the entire linear motion mechanism is then installed on the push plate 101 through the first connection part 2, and then the linear motion mechanism is connected to the frame 201 through the second connection part 2, and finally the threaded segment 11 is threadedly connected to the moving module 301 (brush mechanism) to complete the assembly. When in use, the push plate 101 can be pushed by the cylinder to make the screw 1 drive the moving module 301 to move up and down, thereby realizing the first section of the rising stroke; then the rotating part 4 is rotated, and the rotating part 4 rotates to transmit torque, so that the screw 1 rotates, and then the moving module 301 is driven up and down by the rotation of the thread to complete the second section of the lifting stroke. Through the mutual cooperation between the first connection part 2, the second connection part 3, the rotating part 4 and the linear motion part 5, the rotational movement and the linear movement of the screw 1 do not interfere with each other, and the brush cleaning mechanism is driven by the screw 1 to perform linear movement. Compared with the traditional ball spline, the cost and precision requirements are lower, and screws 1 of different standards can be replaced to adapt to different scenes, which is more practical and more convenient to install.

[0026] Preferably, the first connecting portion 2 includes a first bearing seat 21 and a first bearing 22 disposed on the first bearing seat 21, and one end of the connecting section 12 away from the threaded section 11 is disposed in the first bearing 22.

Specifically, when performing the movement, the guide bar 51 is fixed differently, and the screw rod 1 performs linear movement up and down under the action of the first guide groove 121, and due to the existence of the guide bar 51, the linear and rotary movements do not interfere with each other.
