When the push-pull handle 320 is rotated in the reverse direction, the movable lever 230 slides relative to the inner wall of the accommodating cavity 4121 until the second card 239 abuts against the outer wall of the first housing 412.

The push-pull lock 10 can fix the first housing 412 to the lock body 100, the push-pull mechanism 200 can be slidably disposed on the first housing 412, and the push-pull mechanism 200 drives the first gear 430 to rotate. When the door is closed and the door is closed, the user can slide the sliding assembly 420 on the lock body 100, and the sliding assembly 420 drives the snap block 440 to slide. When the latching block 440 slides into the slot 432, the first gear 430 stops rotating. At this time, the push-pull mechanism 200 is in a locked state and cannot slide on the first housing 412, so that the push-pull lock 10 is in a locked state, which can be avoided. The push-pull lock 10 is manually opened from the outside of the door. Further, the above-described anti-lock mechanism 400 has a simple structure and a low manufacturing cost.

The technical features of the above-described embodiments may be arbitrarily combined. For the sake of brevity of description, all possible combinations of the technical features in the above embodiments are not described. However, as long as there is no contradiction between the combinations of these technical features, All should be considered as the scope of this manual.

The above-described embodiments are merely illustrative of several embodiments of the present invention, and the description thereof is more specific and detailed, but is not to be construed as limiting the scope of the invention. It should be noted that a number of variations and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. Therefore, the scope of the invention should be determined by the appended claims.
