The existing elbow clamp 158 includes an output elbow and a handle, and the handle is rotated to drive the output shaft to move up and down; initially, the output shaft of the elbow clamp 158 presses the first friction disc 153 against the second friction disc 157 downward through the pressure plate 154, the thrust bearing 155, and the driving plate 152. The reduction motor 14 drives the driving plate 152 and the first friction disc 153 to rotate synchronously through the flat key. Under the action of friction, the first friction disc 153 drives the rotating rod 7 to rotate through the second friction disc 157 and the rotating shaft 156 to control the opening and closing of the door leaf 4; during the process, the driving plate 152 rotates around the axis of the output shaft of the reduction motor 14, and the thrust bearing 155 is coaxially arranged with the output shaft of the reduction motor 14 to reduce the friction between the driving plate 152 and the pressure plate 154, and the pressure plate 154 and the elbow clamp 158 do not rotate; by rotating the handle of the elbow clamp 158, the output shaft of the elbow clamp 158 loosens the pressure plate 154 upward, and the first friction disc 153 and the second friction disc 157 are loosened. The power transmission between the reduction motor 14 and the rotating rod 7 is basically disconnected. At this time, when the door leaf 4 is manually rotated, the reduction motor 14 does not interfere with the rotation of the rotating rod 7.
