[0055] In this embodiment, when the hoisting angle of the hoisting device needs to be changed, the limit driving member 18 drives the limit connecting screw 17 to move away from the gear 15, and the movement of the limit connecting screw 17 drives the limit member 16 connected thereto to move away from the gear 15. At this time, the connecting column 5 fixedly connected to the gear 15 can be rotated according to actual construction requirements, and the rotating plate 30 rotates on the annular groove 29 on the upper surface of the fixed seat 14 through the auxiliary wheel 28 provided as the connecting column 5 rotates. After the rotation is completed, the limit driving member 18 drives the limit connecting screw 17 to move close to the gear 15, and the movement of the limit connecting screw 17 drives the limit member 16 connected thereto to move close to the gear 15. When the limit member 16 contacts the gear 15, the gear 15 is limited and fixed, and the connecting column 5 connected to the gear 15 is also fixed.
