The cantilever 22 can be rotated about the top end of the support column 21. One end of the cantilever 22 is in contact with the force application structure 12, and the other end is provided with a lock pin 23; a latch shoe 3 is provided above the latching hook 2, the latch shoe 3 being used for insertion of the latch pin 23.

The application comprises a first state and a second state, when in the first state, the force application structure 12 applies acting force to the cantilever 22, and the contact end of the cantilever 22 and the force application mechanism moves downwards, so that the end of the cantilever 22 with the lock pin 23 rotates upwards, and the lock pin 23 is inserted into the lock pin seat 3 and is in a closed state. When in the second state, the force application structure 12 does not apply an acting force to the cantilever 22, and the end of the cantilever 22 in contact with the force application mechanism moves upward, so that the end of the cantilever 22 with the lock pin 23 moves downward, and at this time, the lock pin 23 is disengaged from the lock pin seat 3 and is in an open state.

Further, the body 11 can move horizontally, and the force application structure 12 can also move horizontally under the driving of the body 11. Force application structure 12 includes the locking piece, and the locking piece setting is provided with the notch in the one end of body 11 on the locking piece, and this notch includes first oblique section, circular arc section and the oblique section of second, and first oblique section and the oblique section of second are connected through the circular arc section, and first oblique section is parallel with the oblique section of second, and first oblique section is the acute angle with horizontal direction's anticlockwise contained angle.

Preferably, the end of the arm 22 remote from the detent 23 is arcuate, the arcuate shape being the same as the arcuate segment.

In this application, application of force structure 12 can remove about under the drive of body 11, and when application of force structure 12 move in opposite directions, the notch applys decurrent effort F to cantilever 22 curved one end, and effort F can decompose into decurrent effort F1 and horizontally effort F2, and wherein effort F2 offsets with the reaction of support column 21, and effort F1 drives cantilever 22 curved one end downstream, and then makes cantilever 22's the other end upwards perk.

Preferably, an insertion hole for inserting the lock pin 23 is formed in the lock pin seat 3, a spring is arranged on the lock pin 23, and the spring is used for generating an acting force for separating the lock pin 23 from the lock pin seat 3 when being inserted into the insertion hole, so that the lock pin 23 can be conveniently separated from the lock pin seat 3.
