In the second embodiment, the positioning structure 4a includes an elastic positioning arm 41a and a positioning groove 42a, a fixed end 412a of the elastic positioning groove 42a is fixedly connected to the inner side of the rotating ring 2a, the positioning groove 42a is disposed outside the fixing member 3a, and the abutting end 411a of the elastic positioning groove 42a is engaged with the positioning groove 42a to realize the positioning after the fixing member 3a and the rotating ring 2a rotate relatively.
Further, the fixed end 412a is fixed to the inner surface of the rotating ring 2a by a connecting portion 43a, and accordingly, the elastic positioning arm 41a is disposed in parallel to and spaced apart from the inner surface of the rotating ring 2 a. The connecting portion 43a can keep a certain gap between the elastic positioning arm 41a and the inner side surface of the rotating ring 2a, which can facilitate the elastic deformation of the elastic positioning arm 41a and the radial movement of the abutting end 411 a. The elastic positioning arm 41a, the connecting portion 43a and the rotating ring 2a are integrally formed as a plate material to improve the structural strength. Here, in other embodiments, the fixed end 412a may also be directly and fixedly connected to the rotating ring 2a, and an included angle may be formed between the elastic positioning arm 41a and the inner side surface of the rotating ring 2a, so that a certain gap exists between the abutting end 411a and the inner side surface of the rotating ring 2a, and the abutting end 411a can move in the radial direction.
Two adjacent positioning grooves 42a are connected, so that the outer side surface of the fixing member 3a is in a zigzag shape, and the positioning protrusion 4111a can enter another adjacent positioning groove 42a after moving out of one positioning groove 42a, thereby facilitating the real-time positioning of the rotating ring 2. Here, in other embodiments, two adjacent positioning grooves 42a may also be arranged at intervals.
In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, so that the scope of the present invention shall be determined by the scope of the appended claims.
