Embodiment Construction
[0022] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings, so that those skilled in the art can better understand the present invention. It should be noted that in the following description, when detailed descriptions of known functions and designs may dilute the main content of the present invention, these descriptions will be omitted here.
[0023] Working process of the present invention is as follows:
[0024] When the hinge gear (12) in the static friction self-locking gear does not rotate, the friction disc (14) is pressed by the thrust spring 2 (13), and the friction disc (14) and the hinge gear (12) squeeze each other. The greater the positive pressure, the greater the maximum static friction. When the torque loaded on the hinge gear is not large enough, the hinge is in a self-locking state. Due to the manual application of force, a large torque is loaded on the hinge gear (12), and the gear overcomes t...
