Preferably, the limiting frame 1 is a U-shaped frame, and is simple in structure and convenient to manufacture.

The tipping tongue mechanism comprises a tipping tongue 21, a fixing piece and a return spring 23. Wherein, the right side face of the tipping tongue 21 facing the right side plate 12 of the limiting frame 1 is provided with a limiting sliding groove 211, and the limiting sliding groove 211 is opposite to the tipping clamping groove 121 on the limiting frame 1. The fixing piece comprises a fixed seat 221 and a sliding rod 222, a contact end of the fixed seat 221 is rotatably contacted with a turning end of the tipping tongue 21, and a free end of the sliding rod 222 deviates from the contact end of the fixed seat 221 and is inserted into the sliding through hole 131 on the limiting frame 1. The return spring 23 is sleeved on the sliding rod 222 and clamped between the fixed seat 221 and the limit plate 13 on the limit frame 1. Thus, when the tipping tongue 21 is forced in the direction towards the top panel (not shown) or the bottom panel 8 of the lock body, the tipping tongue 21 turns over and pushes the fixing piece to compress the return spring 23 and move towards the limiting plate 13 in the limiting frame 1, so as to drive the tipping tongue 21 to retract into the limiting frame 1 in the lock body; when the force applied to the tipping tongue 21 in the direction towards the top panel or the bottom panel 8 of the lock body disappears, the tension of the return spring 23 pushes the fixing piece to be away from the limiting plate 13 in the limiting frame 1, so that the tipping tongue 21 is pushed to move in the direction away from the limiting plate 13, and then the tipping tongue 21 extends out of the tipping tongue notch 61. Preferably, the two sides of the tipping tongue 21 are symmetrically provided with limiting sliding grooves 211.
