[0036] Embodiment 2

[0037] See also Figures 1 to 4 On the basis of the first embodiment, the limiting mechanism 6 further comprises a fixed box 61, the fixed box 61 is fixedly connected to the inside of the support platform 1, the inner wall of the fixed box 61 is rotatably connected to the second screw 62, the outer wall of the second screw 62 is threadedly connected to the second moving block 63, the top of the second moving block 63 is fixedly connected to a fixed frame 64, the inner circle of the fixed frame 64 is rotatably connected to the first limiting sleeve 65, the top of the support platform 1 is fixedly connected to a support seat 69, the inner side of the support seat 69 is fixedly connected to a motor 66, a second limiting sleeve 67 is arranged on one side of the motor 66, the outer wall of the second limiting sleeve 67 is rotatably connected to a support sleeve 68, and the support sleeve 68 is fixedly connected to the top of the support platform 1, so as to facilitate clamping and limiting the pulley.

Since the second moving block 63 and the second screw 62 are threadedly connected, and the outer shape of the second moving block 63 matches the shape of the inner wall of the fixed box 61, the second moving block 63 will slide and limit on the inner wall of the fixed box 61, so that the rotational movement of the second screw 62 can be converted into a linear movement of the second moving block 63, and then the second moving block 63 can drive the first limiting sleeve 65 to move in the direction close to the second limiting sleeve 67 through the fixing frame 64.
