In detail, the housing 1 may be mounted to the ground or wall surface by bolts, the triggering member 12 is mounted to the housing 1, and the housing 1 is mounted beside the door 7 and disposed opposite to the fitting member 8 such that the triggering member 12 is disposed opposite to the fitting member 8. Since the trigger 12 is adjustably connected to the housing 1 along the rotational path of the door 7, the engaging member 8 moves toward the trigger 12 as the door 7 is opened, so that the engaging member 8 rotates the trigger 12. The manner in which the trigger 12 is pivotally connected to the housing 1 may be the same as the manner in which the existing door 7 is hingedly mounted. Alternatively, the locking member 13 may be mounted separately to the wall or the ground, or to the housing 1, such that the locking end of the locking member 13 acts on the mating member 8, so that the locking member 13 mates with the mating member 8. In detail, the rotation end of the trigger 12 is connected to the control end of the locking member 13, so that the trigger 12 controls the opening and closing of the locking member 13. Wherein, the locking member 13 can receive the rotation signal of the triggering member 12 by sensing the triggering member 12. Wherein, the locking member 13 can be an existing electronic lock, when the sensor senses that the mating member 8 triggers the locking member 13 to rotate, the sensor is electrically connected with the controller input of the electronic lock, so as to send an electric signal to the controller and control the electronic lock to lock the mating member 8 through the controller. The sensor may be an angle sensor for sensing the rotation of the trigger 12, an illumination sensor for sensing the moving distance of the trigger 12 or the mating member 8, or a pressure sensor for sensing the pushing of the trigger 12 by the mating member 8. Wherein, the mating member 8 pushes the trigger member 12 to trigger the operation of the locking member 13 as the door 7 is opened by an external force, so that the controller can set the trigger condition of the locking member 13 according to the degree of rotation of the trigger member 12. Alternatively, the existing electronic lock locking fitting 8 may be by way of a clamping or press-down fitting 8. Furthermore, the control mode and the locking/unlocking mode of the electronic lock are both the prior art, and need not be described in detail here.

Alternatively, the first link 10 is vertically fixed to the housing 1, and the locking member 13 and the triggering member 12 are rotatably provided to the first link 10, respectively, wherein the first link 10 has a circumferential direction corresponding to the opening or closing direction of the door 7. In detail, trigger 12 and fitting piece 8 keep away from the one end butt of door 7 and match, and fitting piece 8 lateral part can be dismantled with locking piece 13 and be connected, and after door 7 was opened, fitting piece 8 stretched into in the casing 1 and promoted trigger 12 to trigger 12 drives locking piece 13 and rotates around first connecting rod 10, makes locking piece 13 connect in fitting piece 8 lateral part, and fitting piece 8 can't shift out outside casing 1, and then the open mode of fixed door 7. The trigger 12 and the mating member 8 can be detachably connected by means of a snap or plug connection. The moving range of the engaging element 8 is set according to the opening degree of the door 7 and the length of the engaging element 8, for example, the moving distance of the engaging element 8 is set to be larger than the maximum distance from the trigger 12 to the locking element 13, so that the locking element 13 is abutted against the side of the trigger 12 after the engaging element 8 is inserted into the trigger 12. Wherein, the joint can be through the mode of draw-in groove cooperation. Alternatively, the engagement may be achieved by the locking member 13 passing through a through hole provided in the mating member 8, thereby restricting the movement of the mating member 8 toward the outside of the housing 1. Alternatively, the door 7 may be closed by manually rotating the locking member 13 or the mating member 8 when not in use, thereby disengaging the locking member 13 from the mating member 8. Where the housing 1 should not be construed as a limitation to blocking manual rotation of the locking member 13 or the mating member 8, this can be done in the prior art, such as by a human hand extending into the wave locking member 13 or the mating member 8 from the side of the housing 1. Alternatively, the end of the manual adjustment locking member 13 protruding outside the housing 1. The door 7 is because the external force effect is opened the time mating member 8 and is triggered trigger 12 and rotate to thereby drive locking piece 13 and rotate and lock the mating member 8, can open back automatically fixed convenient to use at door 7. The above-described manner in which the trigger 12 and the locking member 13 are rotatably coupled to the housing 1 by the first link 10 may be replaced by the manner in which the trigger 12 and the locking member 13 are fixed to the first link 10 and the first link 10 is rotatably coupled to the housing 1.
