[0023] As a technical optimization scheme of the utility model, the movable plate 301 is an "L"-shaped structure as a whole, and the movable plate 301 is made of elastic material. The width of the opening groove 303 is three quarters of the diameter of the fixed column 302. The positioning groove 304 is a circular structure, and the diameter of the positioning groove 304 is equal to the diameter of the fixed column 302. The characteristic of plastic deformation under stress can make the opening groove 303 open when the movable plate 301 is moving, so that the fixed column 302 can be just opened and engaged in the inside of the positioning groove 304, thereby realizing the positioning function of the movable plate 301, that is, realizing the anti-locking function.
[0024] As a technical optimization solution of the present invention, a mounting structure 4 is further installed inside the lock body 1 , and the mounting structure 4 includes positioning blocks 401 . The mounting plate 2 is mounted on the back of the lock body 1 through four positioning blocks 401 .
