[0030] Specifically, a connecting block 203 is fixedly connected to the back side of the inner side of the guide rail 201 , and the inner side of the connecting block 203 penetrates to the inner side of the guide device 110 and is fixedly connected to the limiting block 202 , which is arranged in a square structure.

[0031] Through the above technical solution, by setting the limit block 202 and the connecting block 203, the guide rail 201 can be limited and guided during the movement, thereby preventing the guide rail 201 from falling off from the inner cavity of the guide device 110 during the movement.

[0032] Specifically, a slide groove 111 is provided inside the inner cavity of the guide device 110 . The slide groove 111 is arranged in a rectangular structure. The surface of the connecting block 203 is movably connected to the inner cavity of the slide groove 111 .

[0034] Specifically, positioning mechanisms 3 are installed on both sides of the inner cavity of the cabinet 101 and both sides of the back side of the inner cavity of the box body 105. The positioning mechanism 3 includes a positioning plate 301 and an insertion rod 302.

The inner cavity of the housing 105 moves, thereby achieving the function of limiting and guiding the guide rail 201 in the moving state, and then the insertion rod 302 is moved by the movement of the second box 105. Then, when the insertion rod 302 reaches the positioning hole in the positioning plate 301, the insertion rod 302 is restored to its original position under the action of the spring 303. Then, when the second box 105 moves again, the insertion rod 302 moves inward, and then the spring 303 is extended, and then the limiting plate 304 is driven to move, and then reaches When the next positioning hole is reached, the rod 302 is inserted into the positioning hole again under the action of the spring 303, thereby achieving the effect of fixing the box body 105 in the moving state at any time, and then making the box body 105 in the opened state, so as to make it easier for the operator to operate and maintain the battery 106 and the power plug-in 108. Finally, the handle 104 is pushed to the back side by hand, and the box body 105 is moved by the movement of the handle 104, and then the guide rail 201 is driven to slide in the inner cavity of the guide device 110, and then the connecting block 203 is driven to slide in the inner cavity of the slide groove 111, and then the rod 302 is inserted into the last positioning hole inside the positioning plate 301, so as to achieve the effect of fixing and limiting the box body 105 in the working state, and then the power plug-in 108 is used to provide independent working power to each plug-in of the unit device, and then the function of storing electric energy is achieved.
