[0035] With reference to Figure 1 , Figure 2 And Figure 4The outer side of the shell 1 is provided with a protection assembly 6, the protection assembly 6 comprises a protection cover 61, the inner wall of the protection cover 61 is provided with a groove with the same size as the opening of the mobile bin 51 when the protection cover 61 is in the rear end position of the shell 1 and is in the same horizontal position as the mobile bin 51, when the protection cover 61 is in the front side of the shell 1, the inner wall of the protection cover 61 in the same horizontal area as the solar panel 2 is transparent, through the transparent setting, it is ensured that the solar panel 2 can work normally when the protection cover 61 blocks the front end position of the shell 1, the protection cover 61 is arranged on the outer side of the shell 1, the inner wall of the shell 1 is provided with a rotating rod 62 which is fixedly connected, the rotating rod 62 is in the shape of a cylinder, the inner wall of the protection cover 61 is provided with a sliding groove 63, the diameter of the rotating rod 62 is matched with the width of the sliding groove 63, the outer wall of the shell 1 is fixedly connected with a positioning ball 64, the size of the positioning ball 64 is matched with the size of the positioning groove 65, through the size setting of the positioning ball 64 and the positioning groove 65, it is ensured that the positioning ball 64 can enter the positioning groove 65, so as to ensure that the protection cover 61 can be relatively fixed with the shell 1, the material of the positioning ball 64 is rubber, through the setting of rubber, it is ensured that the positioning ball 64 has certain deformation ability, so as to ensure that when the staff applies force to the protection cover 61, the fixed relationship between the protection cover 61 and the shell 1 can be released through the deformation of the positioning ball 64, the inner wall of the protection cover 61 is provided with a positioning groove 65, the outer wall of the protection cover 61 is fixedly connected with a pen rack 7, the material of the pen rack 7 is plastic, the pen rack 7 is placed with a writing pen 8, and a wiping material is arranged above the pen cap of the writing pen 8 for wiping the writing traces.

[0036] Working principle: when the staff needs to use the equipment, first rotate the protection cover 61, then move the protection cover 61 after rotating ninety degrees, so that the shell 1 moves from one end to the other end when the protection cover 61 is in the initial state, then the staff rotates the protection cover 61 again, so that the protection cover 61 rotates ninety degrees relative to the shell 1 and moves to the rear of the shell 1.

[0037] Because the positioning ball 64 and the positioning groove 65 are matched in shape, when the positioning ball 64 enters the positioning groove 65, the shell 1 and the protection cover 61 can be relatively fixed.

[0038] At this time, the staff can smoothly use the calculator to calculate data by pressing the keys of the body 4, when the staff needs to record the related data of the project cost, the staff first pushes the control rod 555 backward, when the control rod 555 moves, the clamping strip 552 moves backward, so that the clamping strip 552 moves out of the groove in the inner wall of the shell 1, at this time, the staff pushes the mounting plate 52 left or right according to needs or preferences.

[0039] When the mounting plate 52 moves, the mounting plate 52 drives the writing board 54 to move towards the direction of moving away from the moving bin 51, since the limiting ring 53 is inside the moving bin 51, when the mounting plate 52 moves to the outside of the protrusion in contact with the limiting ring 53, and the other side of the limiting ring 53 is in contact with the inner wall of the moving bin 51, the mounting plate 52 cannot continue to move due to the blockage of the limiting ring 53.

[0040] At this time, the staff releases the control rod 555, and the clamping strip 552 can move forward under the elastic force of the spring 553, so that the protruding part at the front end of the clamping strip 552 in the area inside the moving bin 51 can enter the hole in the shell 1 at the front end of the moving bin 51 which originally matches the protruding part at the other side of the front end of the clamping strip 552, so that the writing board 54 cannot move left and right due to the clamping strip 552 entering the hole, thereby ensuring that the writing board 54 will not move during use.

[0041] When the use is completed, the staff can make the clamping strip 552 move backward by pressing the control rod 555 outside the moving bin 51, at this time the staff can smoothly push the mounting plate 52 and the writing board 54.

[0042] Subsequently, the staff rotates the protective cover 61 relative to the shell 1, when the protective cover 61 is rotated by ninety degrees, the shell 1 is moved and continues to rotate by ninety degrees, so that the protective cover 61 can cover the front surface of the shell 1 again, thereby achieving the effect of preventing the shell 1 from being hit or falling, and also achieving the effect of preventing the staff from accidentally touching the keys during carrying the device, thereby wasting the power of the device.

[0043] Finally, it should be noted that the above only describes preferred embodiments of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
