[0034] When in use, open the cabinet door 2 and pull the support plate 3 out of the placement cavity of the cabinet 1. At this time, the first limiting shaft 4 slides inside the limiting slide groove 6 and limits the support plate 3 at the same time, and the second limiting shaft 5 slides inside the first slide rail 7. When the support plate 3 slides out of the cabinet door 2, the head end of the support plate 3 will fall down without a support point, and the second limiting shaft 5 will slide out of the first slide rail 7 through the second opening 113. At this time, the second limiting shaft 5 will push the linkage member 110 to slide toward the cavity opening of the placement cavity, and the linkage member 110 will push the energy storage component 8. As the inclination of the head end of the support plate 3 increases, the second limiting shaft 5 slides from the bottom end of the linkage member 110 to its top end, and the linkage member 110 continues to slide toward the cavity opening of the placement cavity. When the first limiting shaft 4 slides to the tail end of the limiting slide groove 6, the first limiting shaft 4 is At the tail end of the support plate 3, the second limiting shaft 5 will slide into the second slide rail 9 by pushing the elastic part inside the third opening 114.

At this time, the linkage block 812 on the linkage member 110 close to the cavity opening of the placement cavity will push the contacting block 85, and the block 85 drives the sliding plate 82 to compress the first return spring 83. When the sliding plate 82 drives the block 85 to slide to the corresponding receiving groove 88, the block 85 is reset by the second return spring 86, and the block 85 is stuck in the interior of the receiving groove 88. At this time, the linkage block 812 continues to slide to the next block 85 until the linkage block 812 slides to the block 85 located at the cavity opening of the placement cavity. At this time, the support plate 3 slides out of the placement cavity, and the support plate 3 is tilted, which is convenient for the staff to repair. When the support plate 3 is in an inclined state, the second limit axis 5 at the rear end of the support plate 3 is located inside the second slide rail 9. When the support plate 3 is pushed into the placement cavity, the hand handle 811 is rotated counterclockwise. At this time, the rotating shaft 89 rotates inside the through hole 815 and the limit card slot 87. At this time, the pushing block 810 pushes the corresponding card block 85 to slide out of the limit card slot 87. At the same time, the card block 85 slides inside the card slot 84 and stretches the second reset spring 86. At this time, part of the card block 85 slides out of the card slot 84, and the card block 85 is located between two adjacent linkage blocks 812. At this time, the first reset spring 83 in a compressed state will drive the sliding plate 82 to reset, and the card block 85 can press against the plane of the linkage block 812, thereby pushing the linkage member 110 to slide to the depth of the placement cavity. At the same time, the staff lifts the support plate 3 in an inclined state to reset.

[0039] The present invention also provides a second embodiment.

[0040] The rotating shaft 89 in the first embodiment can also be an electromagnetic rotating structure, which is connected to the control system of the switch cabinet and can receive signal control from the control system. When the rotating shaft 89 needs to rotate, human-computer interaction can be achieved through the touch screen, and then the forward or reverse rotation of the rotating shaft 89 can be achieved through the control command on the touch screen. At this time, the rotating shaft 89 drives the pushing block 810 to push the card block 85 to reset, so that the energy storage component 8 drives the support plate 3 to slide to the inside of the cabinet 1 for reset. The above-mentioned electromagnetic rotating structure is a prior art, and there are many ways to implement it, which will not be repeated here, and the control method is the existing circuit control system, which uses electrical signals to provide rotation control information for the electromagnetic rotating structure.
