the retaining lug 25 is positioned right in front of the retaining inclined plane 43, so that when the retaining inclined plane 43 moves forwards, the retaining lug 25 can be accurately abutted and pressed to move rightwards by the unlocking cross bar 23.
As a further embodiment, the longitudinal thickness of the retaining projection 25 is greater than the longitudinal thickness of the slider insertion hole 51a, so that after the slider body 51c and the retaining lock 44 are moved leftward and unlocked, the retaining projection 25 is not moved leftward and inserted into the slider insertion hole 51a, but is always kept abutting against the right front end of the retaining slide 41.
As a further embodiment, the right side of the lock cylinder body 31 is provided with a front-rear chute 31a along the front-rear direction on the upper and lower sides of the right side opening 32, and the left side of the retaining slide 41 is provided with a front-rear insert 41a in plug-in fit with the front-rear chute 31 a.
Thanks to the improved technical scheme, the sliding insertion of the retaining slide plate 41 relative to the lock cylinder main body 31 is more stable, and the retaining lock catch 44 and the retaining slide plate 41 are prevented from being pushed to turn left by the torsion moment given by the retaining protruding block 25.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
