[0028] Working principle: when in use, the first lock body 1 and the second lock body 2 are respectively installed on the double doors of the front door of the pet cage, and the toggle shaft 10 is driven to rotate by turning the movable knob 6. Since the toggle shaft 10 is located in the arc groove 9, the toggle shaft 10 moves in the arc groove 9. At the same time, the lower part of the toggle shaft 10 is located in the toggle groove 15, so that the toggle shaft 10 cooperates with the toggle groove 15 when moving, and then drives the rotating block 12 to move, so that the rotating block 12 rotates with the installation axis 11 and the center of the circle. At this time, the first spring 20 and the second spring 21 are driven to stretch, and the rotating block 12 drives the movable hook 14 to disengage from the fixed hook 3, thereby completing the opening of the double doors of the front door; loosen the movable knob 6, and the force applied to the rotating block 12 by the toggle shaft 10 is released, and then under the contraction force of the first spring 20 and the second spring 21, the rotating block 12 drives the movable hook 14 to reset;

[0029] When it is necessary to close the double doors of the front door of the pet cage, close the double doors and repeat the above action, rotate the movable knob 6, and under the drive of the toggle shaft 10, the rotating block 12 drives the movable hook 14 to rotate, and then continue to close the double doors, so that the first lock body 1 and the second lock body 2 are level. Since the movable hook 14 is rotated to a certain angle, it will not collide and interfere with the fixed hook 3. When the first lock body 1 and the second lock body 2 are level, loosen the movable knob 6, and under the contraction force of the first spring 20 and the second spring 21, the rotating block 12 drives the movable hook 14 to reset. At this time, the movable hook 14 is engaged with the fixed hook 3, thereby realizing the locking of the front double doors.
