[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model releases the limit of the positioning block by pulling out the positioning of the inner cavity of the positioning block, and then releases the limit of the second slider. After the limit is released, the positioning block is rotated to a fixed position according to the initial position of the positioning block and the matching setting of the indication mark.

[0038] A circular groove 51 is provided on the top surface of the pan / tilt lifting rod 2 and located on the outer circumference of the rotating groove 3. A circular sleeve 5 is fixedly installed on the outer wall of the rotating rod 4. A first slider 52 and a second slider 53 are fixedly connected to the outer wall of the circular sleeve 5. The first slider 52 and the second slider 53 are symmetrically arranged. The first slider 52 and the second slider 53 are both slidably connected to the inner wall of the circular groove 51. A positioning block 55 is slidably connected to the inner wall of the circular groove 51. The positioning block 55 is fixed to the pan / tilt lifting rod 2 by a positioning pin 512.
