In addition, the swinging member 823 is linked with a rotary button (not shown) outside the casing 1 on the second rotating shaft 15. When the rotary knob is rotated, the swinging member 823 is driven to swing, so as to drive the fixed latch 822 to be in a locked state or In the unlocked state, the fixed latch is manually locked or unlocked. Specifically, when the user rotates the torque inside the house, the swinging member 823 is driven to swing, so that the extension end 8231 pushes the driving unit 821 to the right or left of the drawing along the inner edge of the pushing groove 8211 to move the fixed latch 822 is recessed into or protrudes from the housing 1 to complete unlocking or locking, respectively. In addition, when the swinging member 823 swings toward the transmission surface 8241 of the transmission rod 824 and the protrusion 8232 contacts and pushes against the transmission surface 8241 , the protrusion 8232 can push the transmission rod 824 to swing, and vice versa, it drives the swinging member 823 away from the transmission surface 8241 When swinging, the transmission rod 824 is reset without being pushed by the projection 8232 .

The fixed latch sensor 91 is disposed in the housing 1 corresponding to the fixed latch assembly 82 , and has a first sensing unit 911 , a second sensing unit 912 and a moving rod 913 , wherein the moving rod 913 is linked with the transmission rod 824 , the moving rod 913 is driven by the transmission rod 824 to move the moving rod 913 relative to the first sensing unit 911 and the second sensing unit 912 to sense the state of the fixed latch assembly 82 . More specifically, when the driving unit 821 is forced to move backward (the right side of the figure), the first sensing unit 911 of the fixed latch sensor 91 is not triggered, and the fixed latch sensor 91 can determine the fixed latch component 82 is in the unlocked state, and then transmits an unlocking signal to the driving component 6, so that the driving component 6 pushes the telescopic rod 3 out of the moving member 21 for the user to see through it. Open the door through the handle, on the contrary, when the driving unit 821 is forced to move forward (the left side of the figure), the fixed latch sensor 91 triggers the first sensing unit 911 and the second sensing unit of the fixed latch sensor 91 In the unit 912, the fixed latch sensor 91 determines that the fixed latch group 82 is in the locked state and transmits a locking signal to the driving component 6, so that the driving component 6 retracts the telescopic rod 3 into the moving member 21, At this time, the user cannot open the door through the handle; in addition, when the user uses the key to turn the lock 811 to drive the pendulum block 812 to rotate clockwise, the pendulum block 812 will push the transmission rod 824 to drive the moving rod 913, and also make the pendulum block 812 rotate clockwise. The second sensing unit 912 is not triggered by the moving rod 913 , according to which it is determined that the user unlocks the fixed latch assembly 82 through a key.

The anti-theft latch assembly 83 includes a touch element 831 movably disposed in the casing 1 , a front end of the anti-theft latch 832 connected to the touch element 831 , and a touch lever 833 corresponding to the rear end of the anti-theft latch 832 , wherein the touch lever 833 It is rotatably arranged on the casing 1 through a rotating shaft and has an upper end and a lower end, the upper end extends from the rotating shaft to the rear end of the anti-theft latch 832, and the lower end extends to the anti-theft latch sensor 92, so that the user can move the door to the rear of the anti-theft latch 832. When the door is closed, the anti-theft latch 832 is pressed by the door frame to retract into the housing 1 and drives the touch element 831 to push the upper end of the touch lever 833 to move backward (right side in the figure), and the touch element 831 moves backward (right side in the figure) through the rotating shaft. The lower end of the lever 833 swings toward the direction close to the anti-theft latch sensor 92 to trigger the anti-theft latch sensor 92, so that the anti-theft latch sensor 92 senses the touch lever 833, otherwise, the anti-theft latch 832 is activated when the door is opened. Release the pressing of the door frame and protrude out of the casing 1 to push the upper end of the touch lever 833 to move forward (the left side of the figure), and drive the lower end of the touch lever 833 to move away from the anti-theft latch sensor 92 The direction swings so that the anti-theft latch sensor 92 is not triggered by the touch element 831 .

The anti-theft latch sensor 92 is disposed in the housing 1 corresponding to the touch lever 833 of the anti-theft latch component 83, and is triggered by whether the anti-theft latch sensor 92 is triggered by the lower end of the touch lever 833 to detect whether the door is currently in the Disabled.

To sum up, in the present invention, the toggle element and the driving element are directly connected by the elastic element, so that the driving element drives the toggle element through the elastic element, so that the telescopic rod can protrude from the outside of the moving element, thereby forming a Unlocking mode, on the contrary, when the telescopic rod is retracted into the moving member, it is converted into the locking mode. Since the elastic member has elastic force that can be stretched or compressed, it can ensure that the action end of the elastic member continues to abut the driving member, so When the driving element is actuated, it can immediately drive the action end to move, and there is no delay time for the driving element to idling, so the purpose of saving electricity can be achieved; in addition, this creation can also avoid the inaccurate calculation of the running time of the driving element.
