The positioning plate 3 can be a circular plate body or a plate body of other shapes. The points of the edge of the positioning plate 3 can further form different radius changes, so that the positioning plate 3 is formed in a cam shape, and when the positioning body 5 is matched, different tightness can be provided. The center of the positioning plate 3 has a fixing hole 31. The rotating shaft 2 is embedded in the fixing hole 31 so that the positioning plate 3 can be fixed to the rotating shaft 2. The positioning plate 3 can be disposed in the receiving space 13 of the fixing base 1 .

The positioning plate 3 is provided with a plurality of positioning grooves 32. The positioning grooves 32 are spaced apart from the edge of the positioning plate 3. The number of the positioning grooves 32 is not limited, for example, two, three, and four. Or five. The positioning groove 32 may have a depression such as a V shape or a U shape. The points of the edge of the positioning plate 3 can be formed with different radii, that is, the positioning grooves 32 can be unequally spaced from the axis 21 of the rotating shaft 2, so that the positioning grooves 32 are matched with the positioning body 5. , can provide different tightness.
