A limiting groove 11 is provided on the surface of the slider 10, and the limiting groove 11 is a square groove.

[0027] The reason why the limiting groove 11 is formed on the surface of the slider 10 is that after the fixed shaft 12 rotates clockwise, the limiting block 15 on the surface of the fixed shaft 12 is engaged in the limiting groove 13 to brake the fixed shaft.

[0028] Embodiment 3

[0029] See also Figure 6-Figure 7On the basis of the second embodiment, the fixed shaft 12 is a cylindrical structure, and slider grooves 13 are opened on both sides of the surface of the fixed shaft 12.
