[0007] Preferably, the mounting portion is a mounting frame, which is formed into a horizontal portion and a vertical portion by bending; the end face of the horizontal portion of the mounting frame is welded and fixed to the cleaning frame, and a strip groove is opened on the vertical portion of the mounting frame, and a connecting bolt is screwed into the strip groove, and the connecting bolt is threadedly connected to the support frame, thereby realizing the installation of the mounting frame, thereby completing the installation and fixation of the cleaning frame.

[0008] Preferably, the width of the cleaning frame is equal to the width of the guide wheel, and the front and rear surfaces of the cleaning frame and the front and rear surfaces of the guide wheel are on the same plane, thereby ensuring that the cleaning frame does not occupy the space in the slide rail due to protrusion.

[0009] Preferably, an oil filling hole is also opened on the surface of the mounting frame, and a guide arc plate is also installed at the bottom end of the mounting frame. The guide arc plate and the center of the oil filling hole are on the same vertical line. When the guide wheel needs to be lubricated, the lubricating oil can be poured into the oil filling hole and then guided by the guide arc plate to achieve the purpose of lubrication.
