One end of the angular positioning rotating base 3 is connected with an output shaft of the servo motor 6, and is driven by the servo motor 6 to rotate forwards and backwards. The angle of rotation of the angular positioning rotating base 3 is 0 ° to 120 °. The angular positioning confirmation base 8 is arranged on the side face of the angular positioning rotating base 3, and the angular positioning confirmation base 8 and the angular positioning rotating base 3 are connected through a transmission belt 7.
