The gear set 5422 consists of two gears, one large and one small. The large gear is movably provided on the side wall of the conductive terminal barrel 542, and the small gear is fixed on the outer wall of the positioning screw 5421. The end of the large gear of the gear set 5422 extends through the outside of the side wall of the insulating shell 541 and is engaged with the lower part of the adjusting rod 546, and the gear A movable disk 5423 is threadedly connected to the outer wall of the positioning screw 5421 above the group 5422, and protrusions are provided on the side walls at both ends of the movable disk 5423.

[0042] In this embodiment, when the integrated structure screen needs to be operated, the turntable 654 on the outer wall of the end of the input device drawer 6 is rotated. The turntable 654 drives the meniscus 651 to rotate based on the positioning shaft 652, so that it disengages from the positioning groove on the inner wall of the outer shell 1. At this time, the input device drawer 6 can be pulled out of the outer shell 1 from the connecting port 21 on the flip plate 2, and the input keyboard 61 and mouse 63 and other devices placed in the input device drawer 6 are used to input corresponding operation instructions for the integrated structure screen. In conjunction with the operation buttons on the centralized operation panel 7, the monitoring of the digital monitoring screen 8 on the integrated structure screen and the voltage output of the battery pack 4 can be controlled without opening the flip plate 2, thereby preventing dust from entering the inner part of the outer shell 1 when the flip plate 2 is opened and accumulating on the electronic components to cause damage, which is convenient to use.

[0043] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
