[0028] A spring is installed inside the positioning block 35, so that the positioning block 35 shrinks when under pressure and rebounds when not under pressure. The scraping plate 37 fits against the inclined surfaces on both sides of the moving guide rail 2, and can remove the sundries on the side of the moving guide rail 2, thereby improving the cleanliness of the surface of the moving guide rail 2.

[0029] Specifically, as Figure 4 shown, triangular blocks 4 are symmetrically and fixedly connected to the bottom of the support platform 3 on the left and right.
