[0017] The utility model is further explained below in conjunction with the drawings and specific embodiments of the specification.

[0018] As Figure 1 And 2 The utility model discloses a positioning ring, limiting ring and positioning pin shaft.

[0019] The positioning ring 1 is equipped with annular cavity, and is equipped with multiple circumferential type uniform distribution's guide through hole, and the guide through hole penetrates the annular cavity of the positioning ring 1, and the inner end of the axis of the guide through hole points to the center of the positioning ring 1.

[0020] In the optimization scheme, the guide through hole is two times the number of the arc convex block of the hub, and half of the guide through hole corresponds to the arc convex block.

[0021] The upper end of the positioning ring 1 is fixedly connected with the threaded sleeve 6, the positioning ring 1 is coaxially arranged with the threaded sleeve 6, the threaded sleeve 6 is provided with external thread, the inner ring wall of the limiting ring 2 is provided with internal thread, and the threaded sleeve 6 is screwed with the internal thread of the limiting ring 2.

[0022] The positioning pin shaft 4 is arranged in the guide through hole of the positioning ring 1, and the upper end wall of the positioning ring 1 is provided with multiple long strip-shaped through holes corresponding to the guide through hole and penetrating the guide through hole.

[0023] In the optimization scheme, the two ends of the positioning pin shaft 4 are hemispherical.

[0024] As shown in Figure 3 and 4 , the positioning pin shaft 4 is vertically fixedly connected with the guide pin shaft 5, the guide pin shaft 5 passes through the long strip-shaped through hole and is exposed outside the positioning ring 1, the lower end of the limiting ring 2 is provided with a plurality of arc-shaped guide grooves 21 corresponding to the guide pin shaft 5, the guide pin shaft 5 is inserted in the corresponding arc-shaped guide groove 21, the outer end of the arc-shaped guide groove 21 faces the outer end of the limiting ring 2, and the inner end of the arc-shaped guide groove 21 faces the inner end of the limiting ring 2; when the limiting ring 2 is rotated, the positioning pin shaft 4 can be driven to move along the guide through hole through the arc-shaped guide groove 21 and the guide pin shaft 5.
