The left wall of the protective cabinet door 10 is provided with a mounting bracket 11 that can change the upper and lower positions. The mounting bracket 11 is "concave", and the inside of the mounting bracket 11 is provided with a flippable load-bearing plate 12. The left wall of the load-bearing plate 12 is provided with a mounting groove 13, and the top wall of the mounting groove 13 is an inclined surface that decreases from left to right. The inside of the mounting groove 13 is provided with a flippable support frame 14, and the support frame 14 is "U-shaped" as a whole. A support column 15 is provided at the bottom of the support frame 14, and a position adjustment mechanism for changing its height is provided on the support column 15. The position adjustment mechanism includes a connecting sleeve 18 and an adjusting screw 19.
[0023] The adjusting screw 19 is fixedly mounted on the outer wall of the support column 15, and the outer wall of the adjusting screw 19 is rotatably connected to the bottom wall of the support frame 14. The outer wall of the adjusting screw 19 extends to the interior of the support frame 14, and the connecting sleeve 18 is rotatably mounted inside the support frame 14. The outer wall of the adjusting screw 19 is movably engaged with the interior of the connecting sleeve 18.
[0024] The inner wall of the connecting sleeve 18 is provided with a threaded groove, the outer wall of the adjusting screw 19 is threadedly connected to the inner wall of the connecting sleeve 18, and the rear wall of the support column 15 is fixedly connected with a connecting slide 17 that can be limited;
[0025] The bottom of the support frame 14 is provided with a mounting slot 16 that can be limited. The outer wall of the connecting slide 17 is movably inserted into the interior of the mounting slot 16. The outer wall of the connecting slide 17 is adapted to the interior of the mounting slot 16. There are two mounting slots 16 and two connecting slides 17.
[0026] The front side wall of the support frame 14 is fixedly connected to a connecting shaft 22, and the outer wall of the connecting shaft 22 is rotatably connected to the front side wall of the mounting groove 13. The supporting plate 12 is located in front of the mounting groove 13 to form a mounting cavity 21, and the outer wall of the connecting shaft 22 extends into the interior of the mounting cavity 21.
[0027] The front side wall of the connecting shaft 22 is fixedly connected to the second limit baffle 23. A torsion spring 24 is provided between the second limit baffle 23 and the wall adjacent to the mounting cavity 21. The outer wall of the connecting shaft 22 movably passes through the interior of the torsion spring 24.

[0029] Working principle of the present invention:
[0030] When the present invention is in use, if it is necessary to inspect or maintain a higher position inside the distribution box 1, the upper side end of the supporting plate 12 can be flipped to the left until it is horizontal, and then the lower side end of the support frame 14 can be flipped to the left until it cannot move. At this time, the support column 15 will contact the ground to support the supporting plate 12. The staff can stand on the supporting plate 12 to operate without carrying lifting tools or searching on site, which facilitates the use of the device. Since the top wall of the installation connecting groove 13 is an inclined surface that descends from left to right, the support frame 14 is in an inclined state when working, ensuring that it is in a stable state. The position adjustment mechanism can change the vertical height of the support column 15, thereby changing the overall length of the support column 15 and the support frame 14, thereby changing the height of the supporting plate 12 when it is in working state to meet various needs.
[0031] When the present invention is in use, by rotating the connecting sleeve 18 forward, under the limiting action of the installation slide 16 and the connecting slide 17, the adjusting screw 19 will move the support column 15 downward, thereby changing the overall length of the support frame 14 and the support column 15. The operation is simple and convenient. By rotating the limit baffle 1 20 until it is away from the support column 15, the torsion spring 24 begins to restore its original state and will rotate with the limit baffle 2 23. The connecting shaft 22 will flip the torsion spring 24 until the torsion spring 24 can no longer move. There is no need to manually flip the torsion spring 24, which facilitates the use of the device.
