The working mechanism is located above the base, and the chassis on the working mechanism is rotatably connected to the base. An angle marker is fixed on the circumferential side wall of the base. The angle detection device is located below the chassis and is fixedly connected to the chassis. The angle detection device is connected to the angle marker. When the working mechanism rotates left and right around the base, it drives the angle detection device to move along the arc trajectory of the angle marker. By observing the movement of the angle marker along the arc trajectory, the rotation angle of the angle detection device can be detected, thus determining the rotation angle of the working mechanism.

The processor is communicatively connected to the encoder 2, and the encoder 2 can transmit the detected number of rotations to the processor. The processor can calculate the rotation angle of the working mechanism based on the number of rotations.

The wall is fixedly connected to the first through hole. The bearing seat 44 is sleeved on the stepped shaft 42 and a bearing 43 is provided between the bearing seat 44 and the stepped shaft 42. There are at least two bearings 43, which are distributed at both ends of the bearing seat 44, so that the stepped shaft 42 and the bearing seat 44 can rotate relative to each other. The lower end of the stepped shaft 42 is connected to the gear 3 by a pin, so that the gear 3 can rotate relative to the bearing seat 44, which also makes the gear 3 rotate relative to the frame 1.
