[0023] In the embodiment, the upper end of the cylinder 1 is sleeved with a movable ring 7 for driving a limiting ring 8 to rise and fall. The movable ring 7 is in threaded connection with the cylinder 1. The lower end of the movable ring 7 is fixedly connected with a first rubber pad 10 for preventing wear between the movable ring 7 and the heat dissipation fin 2. The lower end of the movable ring 7 is fixedly connected with the limiting ring 8 for locking the position of the heat dissipation fin 2 in cooperation with a groove 9. The upper end of the heat dissipation fin 2 is provided with the arc-shaped groove 9 for accommodating the limiting ring 8. The lower end of the limiting ring 8 slides and extends into the groove 9.

[0024] In the embodiment, the outer side wall of the cylinder 1 is fixedly connected with a connecting block 12 for supporting a spring 14. The lower end of the connecting block 12 is slidingly inserted with a vertical clamping rod 11 for locking the rotating ability of the movable ring 7 in cooperation with a clamping groove. The upper end of the movable ring 7 is annularly distributed with a plurality of clamping grooves corresponding to the clamping rod 11.
