Abstract
A self-locking device of an endoscope includes a connecting assembly and a fitting assembly. The connecting assembly includes a driven gear and a toggle lever, and the driven gear and the toggle lever are fitted with each other through pins. The fitting assembly includes a driving gear, and the driving gear is engaged with the driven gear through the toggle lever. The self-locking device realizes self-locking with a desired effect through the engagement of the driven gear and the driving gear. Through the design of a lever structure, the self-locking device switches the driven gear and the driving gear between engaged and disengaged states without resorting to an external force of a part, which avoids the use of the part and extends the service life of the device.
