As a preferable technical scheme of the invention, a magnetic attraction belt 29 is fixedly connected in the positioning belt 13, and the sliding rail 11 is made of iron material.

Specifically, the adsorption force between the magnetic attraction belt 29 and the sliding rail 11 can ensure that no gap exists between the positioning belt 13 and the sliding rail 11, so that a better coating effect is realized, and the positioning belt 13 can be ensured to be more stable and smooth in the sliding process.

As a preferable technical scheme of the invention, the sliding rail 11 is arc-shaped, and one side of the positioning block 14, which is attached to the sliding groove 12, is arc-shaped.

Specifically, the sliding rail 11 is designed to be arc-shaped, so that the positioning belt 13 can be effectively guided to move along a preset arc-shaped track, thereby ensuring that the shielding belt 7 can move more smoothly and smoothly in the unfolding and retracting processes, and avoiding distortion, folding or jamming possibly caused by linear movement. The arc-shaped design not only reduces the friction force between the positioning belt 13 and the sliding rail 11, but also enables the movement of the shielding belt 7 to be more natural and smooth, improves the operation efficiency and the service life of the shielding belt 7, and the positioning block 14 arranged on the arc surface can reduce the friction force between the positioning block 14 and the arc-shaped inner wall of the sliding groove 12, reduce the abrasion of the positioning block 14 and the sliding rail 11 and improve the service life of the positioning block 14 and the sliding rail 11.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
