when the safe lock catch structure with bidirectional unlocking is in a locking state: referring to fig. 5-7, the first elastic member 2 in the latch body 3 is limited by the second limiting rib 12 and the third limiting rib 13, so that the latch body 3 is at the middle position (i.e. the second position) of the casing structure 1, and the first limiting rib 34 on the latch body 3 abuts against the fourth limiting rib 41 on the trigger 4, so that the trigger cannot move.

When in a left unlocking state: referring to fig. 8 to 10, the latch body 3 is pressed from left to right, specifically, an operator presses the first key portion 31 to move the latch body 3 to the right, and moves from the second position, that is, the middle position of the housing structure 1, to the first position, one end of the accommodating cavity 33 abuts against one end of the first elastic member 2, the third limiting rib 13 abuts against the other end of the first elastic member 2 to compress the first elastic member, and the first limiting rib 34 of the latch body 3 is staggered with the fourth limiting rib 41 on the trigger 4, at this time, the trigger 4 is pressed by force, the trigger 4 can be pressed, after the trigger 4 is pressed, the second accommodating groove 43 moves towards the first limiting rib 34, and the first limiting rib 34 falls into the second accommodating groove 43, so that the first limiting rib 34 is limited in the second accommodating groove 43, and the latch body 3 cannot rebound. Meanwhile, the first elastic part 2 and the second elastic part 5 are both in a compressed state, and elastic potential energy is stored in the compressed state. When the trigger 4 is released, the second elastic member 5 rebounds to return the trigger 4 to the original position (i.e., the position of the trigger 4 in the locking state), and at the same time, the first elastic member 2 rebounds to return the latch body 3 to the original position (i.e., the second position), thereby achieving the self-locking of the trigger 4.

In a right unlocking state: referring to fig. 11-13, the latch body 3 is pressed from right to left, specifically, the operator presses the second key portion 32 to move the latch body 3 to the left, and moves from the second position, i.e. the middle position of the housing structure 1, to the third position, the second limiting rib 12 abuts against one end of the first elastic member 2, the other end of the accommodating cavity 33 abuts against the other end of the first elastic member 2, the first limiting rib 34 of the latch body 3 is staggered from the fourth limiting rib 41 on the trigger 4, and at this time, the trigger 4 can be pulled by pulling the trigger 4. After the trigger 4 is pulled, the first receiving groove 42 moves towards the first limiting rib 34, and the first limiting rib 34 falls into the first receiving groove 42, so that the first limiting rib 34 is limited in the first receiving groove 42, and the lock catch body 3 cannot rebound. Meanwhile, the first elastic part 2 and the second elastic part 5 are both in a compressed state, and elastic potential energy is stored in the compressed state. When the trigger 4 is released, the second elastic member 5 rebounds to return the trigger 4 to the original position (i.e., the position of the trigger 4 in the locked state), and at the same time, the first elastic member 2 rebounds to return the latch body 3 to the original position (i.e., the second position), so that the trigger 4 is self-locked.
