[0030] The forward and reverse screws 105 are rotatably connected to the base 102 and are located inside the base 102. There are two sliders 106, which are respectively connected to the forward and reverse screws 105 and are arranged opposite to each other. The forward and reverse screws 105 can rotate inside the base 102, and the two sliders 106 move toward or in the opposite direction according to the forward and reverse rotation of the forward and reverse screws 105.

[0031] Secondly, there are two sliding rods 107, which are fixedly connected to two sliders 106, and are slidably connected to the base 102; the two ends of the first rod 108 are rotatably connected to the sliding rod 107 and the connecting plate 103; the two ends of the second rod 109 are rotatably connected to the sliding rod 107 and the connecting plate 103, and the first rod 108 and the second rod 109 are cross-arranged. The sliding rod 107 moves with the slider 106, and the two ends of the first rod 108 and the second rod 109 are rotatably connected to the sliding rod 107 and the connecting plate 103 through a pin, so that the movement of the sliding rod 107 adjusts the angle between the first rod 108 and the second rod 109, and then adjusts the height of the connecting plate 103, so as to achieve telescopic movement inside the base 102. There are multiple first rods 108 and second rods 109, so as to achieve better supporting effect.

[0032] Meanwhile, the guide rod 110 is fixedly connected to the base 102 and penetrates the connecting plate 103. The guide rod 110 penetrates the connecting plate 103, allowing the connecting plate 103 to slide and guide the movement of the connecting plate 103.

[0034] Finally, the operation slot 116 is located at the end of the mounting rod 111. When encountering a dangerous accident and the box body 101 needs to be moved, if the drive motor 114 cannot be started, the mounting plate 115 is disassembled at this time, the first gear 112 and the second gear 113 are separated, and a tool is inserted into the operation slot 116, which is a regular hexagon. The tool is engaged with the operation slot 116, and the forward and reverse threaded screws 105 are driven to rotate by human power to adjust the downward movement of the connecting plate 103 so that the pulley 104 touches the ground.

[0035] When the energy storage device of the optical storage and charging system of the present embodiment needs to be transferred, the driving motor 114 is started to drive the second gear 113 to rotate, and then the first gear 112 and the mounting rod 111 rotate accordingly, the forward and reverse screws 105 rotate, the two sliders 106 move relative to each other, the angle between the first rod 108 and the second rod 109 decreases, and the connecting plate 103 moves downward to expose the pulley 104, and the pulley 104 touches the ground, which facilitates the transfer of the box 101 and is easy to use.
