A reciprocating screw 52 is rotatably connected between the inner bottom end of the other side of the bracket 5 and the rotating plate 3, and the reciprocating screw 52 extends through the lower end of the bracket 5. The wall of the reciprocating screw 52 is threadedly connected to a lifting block 53. A limiting groove 501 is provided in the middle part of the top end of the lifting block 53, and the limiting block 36 is stuck in the limiting groove 501.

[0028] Specifically, a ladder 11 is fixedly installed at the top edge of the lifting mechanism 1 , and the staff will enter the support platform 2 through the ladder 11 .

[0029] Specifically, a plurality of scale bars 26 are provided at the bottom end of the support platform 2 near the circular groove 201, and the pointers 32 correspond to the scale bars 26 up and down.
