[0040] The support rod 25 penetrates the fixing plate 21 and extends upward, and the knob 26 is located outside the fixing plate 21;

[0041] When the support rod 25 moves, the fixed plate 21 remains stationary;

[0042] The first telescopic spring 22 is wrapped around the outer surface of the support rod 25, and the upper shell 11 and the lower shell 12 have hollow structures opposite to the bottom plate 23 and the fixing block 24.

[0043] When the support rod 25 moves downward, it can drive the first telescopic spring 22 to stretch downward to generate elastic force;

[0044] Working principle: when the upper shell 11 and the lower shell 12 need to be installed, a downward pressure is applied to the knob 26 to move the knob 26 downward, and the downward movement of the knob 26 drives the bottom plate 23 and the fixed block 24 to move downward through the support rod 25, and the downward movement of the bottom plate 23 drives the first telescopic spring 22 to stretch, and when the fixed block 24 moves to the outside of the lower shell 12, a rotational force is applied to the knob 26, so that the knob 26 drives the bottom plate 23 and the fixed block 24 to rotate through the support rod 25, and when the fixed block 24 rotates to correspond to the position of the fixing groove 27, the force applied to the knob 26 is released, and under the elastic force of the first telescopic spring 22, the fixed block 24 and the knob 26 are driven by the first telescopic spring 22 to move toward each other, thereby fixing the upper shell 11 and the lower shell 12;

[0045] When the upper shell 11 and the lower shell 12 need to be disassembled, the above steps can be performed in reverse.

[0046] See also Figure 4 As shown, this embodiment is based on the above embodiment and also includes:

[0047] The limiting assembly includes a support plate 31, a slide slot 32, a fixing hole 33, a movable plate 34, a second telescopic spring 35 and a movable column 36;

[0050] The inner end of the movable column 36 is located inside the upper end of the movable plate 34, and the movable plate 34 is located outside the gate 13;

[0051] When the movable column 36 is located inside the lower end of the support plate 31, the movable plate 34 is located at the lower end of the inner side of the support plate 31 and above the gate 13;

[0052] Working principle: when it is necessary to close the switch 13 to cut off the power to the distribution box, the switch 13 is tilted toward each other. At this time, an inward force is applied to the movable column 36 to move the movable column 36 inward. The inward movement of the movable column 36 drives the second telescopic spring 35 to be compressed. When the movable column 36 moves out of the fixing hole 33, a downward force is applied to the movable plate 34 to make the movable column 36 move downward along the slide groove 32. When the movable column 36 moves to the fixing hole 33 at the lower end, it moves outward under the elastic force of the second telescopic spring 35. The movable column 36 moves to the inside of the fixing hole 33. The movable plate 34 is limited and fixed by the movable column 36 at the lower end position on the inner side of the support plate 31, and is located above the switch 13, blocking the switch 13 to prevent the switch 13 from rotating to power the distribution box due to misoperation.
