[0056] The telescopic mechanism 4 is arranged above the stabilizing power supply body 102, and the telescopic mechanism 4 comprises a rotating strip 404 arranged in the box body 1, and a cylindrical body 405 fixedly installed at one end of the rotating strip 404. The telescopic mechanism 4 is used for adjusting the position of the stabilizing power supply body 102.

[0057] Specifically, as shown in Figures 1-8 two fixed strips 201 are fixedly installed on the side surfaces of each other, the connecting strip 301 is fixedly installed on the side surface of the connecting plate 302, the connecting plate 302 is fixedly installed on the side surface of the moving strip 303, and the top surface of the moving strip 303 is provided with two adjusting grooves 306.

[0058] In this embodiment: the cylindrical part 405 engages with the through groove 402, thereby moving the mounting strip 401.

[0059] Specifically, such as Figures 1-8 As shown, a connecting shaft 403 is fixedly installed at one end of the rotating bar 404. The upper end of the connecting shaft 403 extends through the inner wall of the upper end of the housing 1 via a bearing seat to the top of the housing 1. An adjusting plate 407 is fixedly installed on the outer wall of the upper end of the connecting shaft 403. Two screw holes 409 are opened on the top surface of the housing 1. The two screw holes 409 are set vertically. The adjusting plate 407 is fixedly connected to the screw holes 409 by a butterfly bolt 408.

[0060] In this embodiment: the adjustment plate 407, butterfly bolt 408 and screw hole 409 are provided to adjust the position of the adjustment plate 407 and drive the connecting shaft 403 to rotate a certain angle.

[0061] The specific solution is as follows: When removing the voltage regulator body 102 for maintenance, tighten the butterfly bolt 408, rotate the adjusting plate 407 by 90 degrees and fix it with the butterfly bolt 408. This causes the connecting shaft 403, rotating bar 404, and cylinder 405 to rotate. The cylinder 405 slides on the inner wall of the through groove 402, pushing the mounting bar 401 to move. This, in turn, moves the fixing bar 201 and the voltage regulator body 102, allowing the voltage regulator body 102 to move out of the housing 1. At this time, the fixing bar 201 moves the connecting bar 301, connecting plate 302, and moving bar 303. The adjusting groove 306 on the moving bar 303 cooperates with the adjusting column 307, causing the support bar 305 to rotate at a certain angle. The support bar 305 supports the bottom surface of the voltage regulator body 102, ensuring that the voltage regulator body 102 is more stable when it is moved out of the housing 1, and is less likely to fall and be damaged. After pushing the voltage regulator body 102 upwards and outwards... Pulling the power supply body 102 allows for easy removal and disassembly, a quick and convenient process for maintenance. During installation, holding the power supply body 102 and pushing it and the concave frame 206 together causes the locking pin 207 on the concave frame 206 to move to the inner wall of the slot 203, loosening the power supply body 102. Under its own weight, the power supply body 102 moves the concave frame 206 and the locking pin 207 to the bottom of the slot 203. Simultaneously, the slot 208 connects to the fixing post 204. The power supply body 102 is then moved into the housing 1, where the connecting post 210 connects to the locking hole 209, fixing and limiting the concave frame 206, further securing the power supply body 102. This not only ensures greater stability of the power supply body 102 but also improves installation efficiency.

Accordingly, any one of the above-mentioned embodiments or different embodiments can be combined, steps can be implemented in any order, and there are many other changes of different aspects of the present application as described above, which are not provided in details for the sake of simplicity.
