[0050] The square shaft portion 400 is connected between the lock core portion 200 and the handle 310. The rotation of the handle 310 is transmitted to the lock core portion 200 through the square shaft portion 400. The rotation of the square shaft portion 400 can operate the lock core portion 200 to be released or locked.

[0051] The coil spring 500 is sleeved on the spring installation cylinder 321 and matches with the handle 310. The coil spring 500 provides elastic force for the handle 310 to return to its original position.

[0052] The anti-locking part 600 includes a fixing pin 610 and a switch paddle 620 which is buckled in the buckle part 314 and at least partially exposed from the handle 310. The switch paddle 620 is matched with the square shaft part 400. The buckle part 314 is provided with two longitudinal fixing positions 317 corresponding to the switch paddle 620 in the length direction of the handle 310 and the position is adjustable. The fixing pin 610 is elastically supported in the thickness direction of the handle body end 311. A locking position is provided on the sliding seat 320 corresponding to the fixing pin 610. The sliding release of the switch paddle 620 and the combination of the fixing pin 610. The fixing pin 610 can be sleeved on a coil spring so as to be elastically supported. The downward pressure and release of the fixing pin 610 are achieved by sliding the switch paddle 620. When the switch paddle 620 is combined with the fixing pin 610, the fixing pin 610 limits the rotation of the square shaft portion 400 (that is, limits the rotation of the handle 310) through the switch paddle 620; when the switch paddle 620 and the fixing pin 610 are released, the combination between the fixing pin 610 and the switch paddle 620 is released, so as not to hinder the rotation of the square shaft portion 400. The anti-locking portion 600 is fixed by the buckle portion 314 on the handle 310, achieving a simple, convenient and stable effect.

[0053] In summary, the sliding seat 320 is fixedly adjustable in the width direction of the outer surface of the lock housing 100, so as to adapt to single-pane and double-pane door leaves of various sizes; the handle 310 is provided with a buckle portion 314, and two longitudinal fixing positions 317 are correspondingly arranged on the buckle portion 314 in the length direction of the handle 310 for position adjustment, and the sliding release of the switch paddle 620 and the combination with the fixing pin 610 simplify the fixing and maintenance of the switch paddle 620.
