Abstract
A self-locking device of an endoscope is provided. The endoscope includes a housing and a toggle assembly. The toggle assembly includes a toggle support, an elastic support and a toggle handle. The toggle handle is sleeved on the toggle support. An inner side of the toggle support is provided with a toggle lever and a friction piece. One end of the toggle lever is hinged to the toggle handle, and the other end of the toggle lever is not connected to the friction piece. The toggle lever has an L-shaped cross section, with a middle bend fixed to the toggle support. The toggle lever is hinged to the toggle support through a first pin. When being stressed, the toggle lever is rotatable around the first pin, so as to push the friction piece to move.
