[0015] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0016] like Figure 1 and Figure 2 As shown, this embodiment provides a tightening switching mechanism, including a substrate 1, a switch 9 and two sleeves 10, the switch 9 is mounted on the substrate 1, and the two sleeves 10 are mounted on the driving end of the switch 9;

[0017] The switch 9 includes a switching cylinder 11, a connecting rod 13 and a mounting seat 16. The switching cylinder 11 is mounted on the base plate 1, and the output end of the switching cylinder 11 extends and is placed below the base plate 1. The mounting seat 16 is fixedly mounted below the base plate 1. One end of the connecting rod 13 is rotatably mounted on the output end of the switching cylinder 11, and the other end of the connecting rod 13 is rotatably connected to the mounting seat 16. Both sleeves 10 are rotatably mounted on the mounting seat 16 and are both transmission-connected to the connecting rod 13. The central axes of the two sleeves 10 are vertically arranged. Specifically, the driving end of the switching cylinder 11 is provided with a Y-shaped cylinder joint 12 rotatably connected to the connecting rod 13.
