Because the movable screw 22 is located in the recess of the fixed frame 6, the clamping plate 23 is also located in the recess of the fixed frame 6. Therefore, when the movable screw 22 is rotated, the clamping plate 23 will not rotate. Then, the two groups of clamping plates 23 can be used to position the cargo to improve the stability during hoisting. In order to facilitate hoisting, the auxiliary plate 26 can be rotated so that the auxiliary plate 26 is parallel to the surface of the fixed frame 6, and then the fixing bolt 28 is screwed into the thread groove 27 for fixing, so that the auxiliary plate 26 can be used to support larger cargo to improve safety.

[0036] Working principle: In actual use, the drive motor 3 can be used to drive the take-up roller 2 to rotate and reel in the sling 4. When the fixed frame 6 is lifted, the guide pulley 10 can be used to limit the rise in the lifting hole 16 to prevent the fixed frame 6 from shaking, which has a stabilizing effect on the fixed frame 6 and makes the fixed frame 6 rise stably.
