[0026] In order to solve the problem that when a BIM-based handheld display device is in use, the cleaning cotton pad is not in close contact with the display screen, reducing the display effect of the BIM-based handheld display device on the building information model, please refer to Figures 1 to 5 , the structure of the device body is a display screen main body 1 for displaying a building information model and a dust removal component 2. BIM is used to describe those computer-aided designs that are mainly three-dimensional graphics, object-oriented, and related to architecture. The three-dimensional building information model of BIM is displayed through the set display screen main body 1, and the set dust removal component 2 performs dust removal treatment on the display screen surface of the display screen main body 1 to prevent dust from accumulating on its surface, thereby improving the display effect of the display device on the building information model of BIM. The dust removal component 2 includes a linear motor 3 and a cleaning plate 6. The set linear motor 3 provides power. The fixed end of the linear motor 3 is welded to the display screen main body 1 to fix the position of the linear motor 3. Connecting plates 4 are respectively fixed to both sides of the moving part of the linear motor 3, so that the two connecting plates 4 are fixedly connected to the moving part of the linear motor 3. During the movement transmission process of the moving part of the linear motor 3, the two connecting plates 4 are driven to move longitudinally synchronously. The side surface of the connecting plate 4 is slidably connected to a limiting rod 5 through a through groove provided, and the set connecting plate 4 fixes the moving path of the limiting rod 5.

[0027] The end faces of the two limiting rods 5 are welded to the cleaning plate 6, so that the two limiting rods 5 are fixed on the same side of the cleaning plate 6, thereby fixing the moving path of the cleaning plate 6. A cotton plate 7 is fixedly connected to the side of the cleaning plate 6 close to the limiting rod 5, realizing the synchronous movement of the cleaning plate 6 and the cotton plate 7. The side of the cotton plate 7 is slidably connected to the display screen surface of the display screen main body 1. By arranging the cotton plate 7 to move longitudinally along the display screen surface of the display screen main body 1, dust removal treatment is carried out on the display screen surface of the display screen main body 1, thereby improving the display effect of the display device on the building information model of BIM. A limiting block 8 is welded to the end of the limiting rod 5 far from the cleaning plate 6. The arranged limiting block 8 prevents the limiting rod 5 from detaching from the connecting plate 4 during the movement, improving the structural stability of the device components. A boosting spring 9 is sleeved on the side of the limiting rod 5. The two end faces of the boosting spring 9 are respectively fixedly connected to the limiting block 8 and the connecting plate 4. The arranged boosting spring 9 provides an elastic thrust, strengthening the contact tightness between the cotton plate 7 and the display screen surface of the display screen main body 1 during the transmission process, enhancing the dust removal effect of the cotton plate 7, and further improving the display effect of the display device on the building information model of BIM.

[0028] The sides of the two limiting rods 5 are arranged on both sides of the display screen main body 1, and the two limiting rods 5 do not contact the display screen main body 1, providing sufficient space for the longitudinal movement of the two limiting rods 5 and improving the structural stability of the device components. An I-shaped grip rod 10 is welded to the bottom surface of the display screen main body 1. The arranged grip rod 10 is used for holding the display device, improving the usability of the display device. A threaded rod 11 is fixedly connected to the bottom surface of the grip rod 10. The threaded rod 11 is threadedly sleeved with a threaded sleeve 12, enabling the threaded rod 11 to move longitudinally along the threaded path of the threaded sleeve 12, facilitating the adjustment of the longitudinal height of the display device and adapting to the longitudinal usage height requirements of the display device. The side of the threaded sleeve 12 is in interference fit with a limiting bearing 13.

[0029] The arranged limiting bearing 13 fixes the rotation position of the threaded sleeve 12, improving the structural stability of the device components. There are two push blocks 16 arranged at the top of the limiting bearing 13, and the two push blocks 16 do not contact the limiting bearing 13. The adjacent sides of the two push blocks 16 are welded to the threaded sleeve 12, facilitating the rotation of the threaded sleeve 12 by pushing the push blocks 16 and improving the usability of the device. A support rod 14 is fixedly connected to the inner ring of the outer ring of the limiting bearing 13 to fix the position of the limiting bearing 13. The bottom end of the threaded rod 11 extends into the support rod 14. The top of the support rod 14 is slidably connected with a movable plate 17 through a cavity opened. The top surface of the movable plate 17 is fixedly connected to the threaded rod 11. The arranged movable plate 17 prevents the threaded rod 11 from detaching from the threaded sleeve 12 during longitudinal movement, improving the functional structural stability of the device. A base 15 is welded to the bottom surface of the support rod 14. The arranged base 15 provides a supporting function for the display device.
