Preferably, the load-bearing bearing is a tapered roller bearing, and the centralizing bearing is a cylindrical bearing. Bearings or deep groove ball bearings; a plurality of external gears meshing with the central gear are arranged in the housing, and each external gear is evenly distributed around the circumference with the gear shaft of the central gear as the center. A motor; the motor (3) is preferably a stepping motor. An upper pull rod coaxially arranged with the central gear shaft is fixedly connected to the central position of the casing.

Further, the upper end of the upper pull rod is provided with radial holes or connecting flanges.

Further, the number of the external gears is two, and the two external gears are evenly distributed around the circumference with the axis where the gear shaft of the central gear is located as the center of the circle.

Further, the number of the external gears is three, and the three external gears are evenly distributed around the circumference with the axis where the gear shaft of the central gear is located as the center of the circle.

Beneficial effect: The utility model is provided with a steering member between the middle position of the large object hanging tool and the upper pull rod to carry out the beam, and the steering member includes a central gear and a plurality of external gears meshing with the central gear. It is driven by the electric motor, which provides enough power for the angle adjustment of the beam; at the same time, the center gear of the steering component is arranged coaxially with the center of the beam, and the center of gravity of the entire steering component is set at the center of the beam, which ensures that the steering component drives the beam to adjust. The stability of the angle in the process; at the same time, the motor adopts a stepper motor, which can ensure the accuracy of the adjustment process angle.
