Specifically, the limiting rod 33 plays a role in positioning the limiting spring 31, so as to prevent the limiting spring 31 from being disengaged from the limiting member 3, and the limiting spring 31 will stably push the limiting member 3 to abut against the lock tongue 2.

As shown in fig. 1, 2 and 5, a connecting portion 41 is formed on the unlocking insertion rod 4, a linkage hole 42 is formed on the connecting portion 41, and a control member 5 inserted into the linkage hole 42 is connected to the connecting portion 41, an inclined surface 51 capable of abutting against an inner wall of the linkage hole 42 is formed on the control member 5, and the inclined surface 51 can push the unlocking insertion rod 4 to extend into the unlocking hole 24. Specifically, the unlocking part 20 is installed on a door frame or a door panel, the unlocking rod 4 can extend out of the side end and align to the unlocking hole 24 in the lock tongue 2, the control piece 5 is inserted into the linkage hole 42 from the direction in front of or behind the door, the control piece 5 is pressed in front of the door, the control piece 5 can pass through the inclined surface 51 to push the inner wall of the linkage hole 42, so that the unlocking rod 4 moves towards the unlocking hole 24 in the lock tongue 2, and the unlocking and door opening are completed. The number of the linkage holes 42 can be set according to the requirement, for example, when the number of the linkage holes 42 is 1, the control piece 5 can be singly inserted into the linkage holes 42 from the direction of the front or the back of the door, so that the door opening mechanism can be opened only from a single direction inside or outside the door; when the number of the linkage holes 42 is 2, the control member 5 can be respectively inserted into the corresponding linkage holes 42 from the front and back directions of the door, so that the user can open the door opening mechanism from the inside and the outside of the door. The unlocking part 20 can be arranged in a mounting seat and fixed in a corresponding door frame or a corresponding door plate by the mounting seat, and the control part 5 can be connected with a corresponding key for decoration after extending out of the mounting seat, so that the whole mechanism is more attractive.

As a modified embodiment, an insertion block 52 is formed on the control member 5 and penetrates through the linkage hole 42, a reset block 53 with elasticity is formed on the insertion block 52, and the reset block 53 is in an open shape and penetrates through the linkage hole 42 in the direction of the inclined surface 51. Specifically, the control member 5 is connected to the linkage hole 42 through the matching of the inserting block 52 and the reset block 53, when the control member 5 is pressed, the reset block 53 is opened and close gradually towards the linkage hole 42, at this time, the reset block 53 has an opening trend due to self elasticity, and when the control member 5 is no longer pressed and released, the reset block 53 pushes the control member 5 to move and reset towards the direction far away from the linkage hole 42 while being opened.

As an improved embodiment, the unlocking insertion rod 4 is sleeved with a positioning spring 43 which is abutted against the connecting portion 41, the positioning spring 43 enables the unlocking insertion rod 4 to have a tendency of being far away from the bolt 2, a matching groove 54 is formed in the control member 5, a supporting rod 541 is formed in the matching groove 54, and a pressing spring 55 which is abutted against the inner wall of the matching groove 54 is sleeved on the supporting rod 541. Specifically, when the unlocking insertion rod 4 is pushed to extend out of the mounting seat, the positioning spring 43 is pushed by the connecting portion 41 to be extruded, because the unlocking insertion rod 4 is mounted in the mounting seat, the positioning spring 43 can be abutted against the inner wall of the mounting seat, and when the unlocking insertion rod 4 is not pushed any more, the positioning spring 43 can rebound and push the positioning portion 41 to reset the unlocking insertion rod 4 and return to the mounting seat. Similarly, when the control member 5 is pressed, the pressing spring 55 abuts against the mounting seat and is pressed, and when the control member 5 is no longer pressed, the pressing spring 55 rebounds to push the control member 5 to reset.
