[0039] Among them, through the movement of the sliding plate 34, the second support rod 35 is driven to rotate along the third rotating seat 36, so that the storage box 1 can be supported through the cooperation of the first support rod 31 and the second support rod 35, which is convenient for technicians to observe the data on the computer main body 24 and is also more convenient for technicians to use.

[0040] As Figures 1 - 9 shown, the usage method steps of the accounting device are as follows: Step 1, when the computer main body 24 needs to be used, the first support rod 31 can be pulled first, so that the first support rod 31 rotates along the first rotating seat 30, so as to drive the second rotating seat 33 to move, and then drive the sliding plate 34 to move, and then drive the second support rod 35 to rotate along the third rotating seat 36, so that the storage box 1 can be supported through the cooperation of the first support rod 31 and the second support rod 35, which is convenient for technicians to observe the data on the computer main body 24.

[0041] Step 2: When a technician needs to use the accounting device, the technician first rotates the cover 2 and then pulls the handle 5, thereby driving the sunshade 4 to rotate around the transmission shaft 6, thereby driving the gear 7 to rotate, thereby driving the first rack 8 and the second rack 9 to move, thereby driving the connecting plate 15 to move, thereby driving the computer main body 24 to move.

[0042] Step 3: After the sunshade 4 continues to rotate, the sunshade 4 will enter the inside of the covering plate 10 and push the block 11, thereby driving the first slide bar 12 to move, thereby driving the pull rod 13 to move, thereby driving the first spring 14 to retract. When the sunshade 4 moves to the specified position, the first spring 14 will drive the pull rod 13 to move, thereby driving the block 11 to move, thereby fixing the position of the sunshade 4 through the block 11, thereby enabling the sunshade 4 to block the light irradiating on the computer main body 24, thereby ensuring that the data cannot be clearly seen when the computer main body 24 is in use.
