[0028] How this utility works:

[0029] During use, the fixing plate 2 is placed inside the required docking distribution box, and the fixing knob 3 is rotated to rotate the fixing screw 4 so that the push plate 5 moves to the right along the groove, so that the fixing plate 2 is fixed to the required installation position of the distribution box. After installation, the docking structure 7 is rotated to rotate the docking seat 8 to the inside of the limiting groove of the fixing plate 2 on the back of the other opening and closing mechanism 1, and then the docking seat 8 is pressed and moved inward at the same time, and then the block 10 is released so that the block 10 extends into the docking groove, so that the first opening and closing mechanism 1 is connected with the second opening and closing mechanism 1, which solves the problem that the opening and closing mechanism 1 is inconvenient to be installed inside the distribution box and the opening and closing mechanism 1 needs to be opened and closed after being installed in the distribution box. The problem that the opening and closing mechanism 1 is prone to shaking when closing the gate, causing the opening and closing mechanism 1 to be dislocated or even fall off, is solved. The opening and closing mechanism 1 can be installed inside the distribution box and multiple opening and closing mechanisms 1 can be connected to enhance their stability by only rotating the fixing knob 3, which greatly enhances the installation efficiency of the opening and closing mechanism 1. By rotating the clamping plate knob 17, the clamping plate lead screw 18 is rotated to rotate the lower clamping plate 19 to move upward, and the switch structure of the opening and closing mechanism 1 is clamped and fixed by the upper clamping plate 16 and the lower clamping plate 19. By docking the threaded protrusion of the lower limit rod 15 on the first opening and closing mechanism 1 with the threaded hole of the upper limit rod 13 of the second opening and closing mechanism 1, and then rotating the threaded column protrusion to make the first opening and closing mechanism 1 open. The lower limit rod 15 of the closing mechanism 1 is connected to the upper limit rod 13 of the second opening and closing mechanism 1, and all the opening and closing mechanisms 1 are connected by analogy. When the switch structure of the first opening and closing mechanism 1 is opened or closed, the switch structures of the remaining opening and closing mechanisms 1 can be driven to open or close the gates, which solves the problem that when the opening and closing mechanisms 1 are in use, multiple opening and closing mechanisms 1 need to be opened or closed, which wastes a lot of time. The switch structures of multiple opening and closing mechanisms 1 can be connected, so that the first opening and closing mechanism 1 can be opened or closed to control all the closing mechanisms 1, which greatly reduces the time for operators to open or close the gates. After the wiring of the opening and closing mechanism 1 is completed, the placement screw 22 is rotated by rotating the placement knob 21, so that the upper baffle 23 moves downward, and the line can be clamped and fixed by the upper baffle 23 and the placement seat 20, and then the lower flame retardant block 25 and the upper flame retardant block 24 can slow down the speed of the line burning backward when the line burns, which solves the problem that the line is easy to fall off due to the shaking of the opening and closing mechanism 1 when the opening or closing mechanism 1 is opened or closed, and the fire is easy to cause when the opening and closing mechanism 1 burns due to overload. The line can be clamped and fixed, and the burning speed can be slowed down by the two flame retardant blocks when the line burns, which greatly enhances the safety of the opening and closing mechanism 1.
