[0023] Understandably, the design of the housing 1 and the cover 7 provides good protection for the display screen body 4, preventing damage during movement and use. The wheel set 6 is a self-locking pulley in the prior art, so this application will not elaborate on its self-locking principle.

[0024] Please see Figures 2 to 4In this embodiment, the adjustment component includes a movable seat 205 fixed to the top of the connecting seat 3. An arc-shaped track 204 slides inside the movable seat 205. Arc-shaped grooves 210 are provided on both the upper and lower sides of the arc-shaped track 204. Slide rods 209 that slide in an arc shape with the arc-shaped grooves 210 are fixed on both the front and rear side walls of the inner cavity of the movable seat 205. A motor 206 is fixed to the front side of the movable seat 205. The output shaft of the motor 206 passes through the front side of the movable seat 205 and extends into the interior of the movable seat 205 and is welded with a gear 207. A rack 208 meshes with the outer side of the gear 207.

[0025] The lifting assembly includes an electric push rod 201 fixed to the back wall of the inner cavity of the cabinet 1.

Positioning plates 211 are welded to the opposite sides of the two connecting blocks 203. Two positioning strips 212 are welded to the left and right side walls of the inner cavity of the cabinet 1 and along one side of the back wall of the inner cavity. When the cover plate 7 is opened and the electric push rod 201 is started, the two positioning plates 211 can slide on the outside of the two positioning strips 212 respectively, so that the display screen body 4 can be completely moved out of the cabinet 1. When the electric push rod 201 is stopped, the two positioning strips 212 still slide inside the two positioning plates 211 respectively.

[0026] The arc track 204 has a semi-circular cross-section. There are at least two racks 208, which are evenly distributed on the inner arc surface of the upper side of the arc track 204. The movable seat 205 slides in an arc shape on the outer side of the arc track 204. The front side wall of the inner cavity of the movable seat 205 is in contact with the bottom arc surface of the arc track 204. When the motor 206 is started, the gear 207 will start to rotate. The engagement of the gear 207 and the rack 208 will make the movable seat 205 slide in an arc trajectory on the outer side of the arc track 204, which can quickly change its display angle and improve its practicality. The two positioning strips 212 have a T-shaped cross-section and slide back and forth inside the two positioning plates 211 respectively. The top of the arc track 204 is welded to the bottom of the two connecting blocks 203 respectively. When not in use, the display screen body 4 is reset to the front end of the arc track 204 and moved into the cabinet 1. The cover plate 7 is then put back on the cabinet 1 to effectively protect the display screen body 4.

[0027] Understandably, the design of the adjustment mechanism 2 enables the lifting and angle adjustment of the display screen body 4. Through the cooperation of the motor 206 and the gear 207, the angle of the display screen body 4 can be automatically adjusted, making the operation simple and quick, adapting to different display needs and environments, and improving the flexibility and applicability of the display screen body 4. The wheel set 6 installed on the back side of the housing 1 makes the display screen body 4 easy to move and position, making it convenient for use in different occasions. Furthermore, the design of the housing 1 and the cover plate 7 provides good protection for the display screen body 4, preventing damage during movement and use.
