Problems solved by technology
[0002] At present, wear-resistant materials such as alloys or ceramics are widely used in dentures. During the machining process, the friction between the tool and the workpiece generates a lot of heat. A cooling system needs to be installed to cool the tool and workpiece processing parts to prevent the heat from being transferred to the bed and affect the matching accuracy of the various parts. And structure, usually a water-cooling system with low cost and good cooling effect. The main shaft of the small dental grinder protrudes from the housing to the top of the workbench, and the housing is provided with a relief port for the main shaft to protrude and move in the space , in the prior art, the pleated shield is installed on the side of the main shaft and the relief port, which can avoid the contamination and corrosion of the main shaft drive parts by splashing droplets generated by the water cooling system, but the deformation of the pleated shield is mainly due to the movement of the main shaft. Concentrated at its creases, it is prone to cracks and damage after long-term use, and it is not easy to be found, which is extremely harmful to the equipment and is not conducive to the daily maintenance of the equipment. higher cost

The invention discloses a flexible moving protection cover for a small dental grinding instrument. The protection cover comprises a central sleeve arranged at the center, a circular connection edge surrounding the outside of the central sleeve and a flexible cover. The flexible cover is connected between the central sleeve and the circular connection edge, and a cover structure is formed in a circular region between the central sleeve and the circular connection edge. The flexible moving protection cover for the small dental grinding instrument is free of folds and creases in the natural state, easy to manufacture and maintain and clean daily, free of deformation concentration points during use, not prone to damage and long in service life.
