[0048] The remaining structure is the same as that of Example 2.

[0049] Reference Figures 1 to 7 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a display device for exhibition services.

[0050] When using the device, the staff first starts the motor 201 by using the controller. The operation of the motor 201 can make the first screw 202 rotate. During the rotation of the first screw 202, the main crown gear 204a can be driven to rotate. The rotation of the main crown gear 204a can also drive the secondary crown gear 204b to rotate. The rotation of the secondary crown gear 204b can drive the secondary display plate 204f to expand outwards by using the second screw 204e. After the secondary display plate 204f is unfolded, the direction of the motor 201 can be rotated to drive the main pull ring 302a to move downward on the surface of the first screw rod 202. The downward movement of the main pull ring 302a can be used to drive the vertical rod 302e to move downward by using the secondary pull ring 302b. During the downward movement of the vertical rod 302e, the pull rod 302f can be used to squeeze the surface of the pull groove 302g, so that the pull groove 302g is squeezed and drives the support rod 301d to move backward. When the support rod 301d moves backward, it can squeeze the rotating rod 301b. After the rotating rod 301b is squeezed, the guide rod 302f can be used to squeeze the surface of the pull groove 302g. The block 301f drives the rotating gear 301a to move to the surface of the first screw rod 202 to a meshing state. After the rotating rod 301b is squeezed, the squeezing block 203i can also be squeezed, so that the squeezing block 203i moves downward after being squeezed. At the same time, the fixed ring 203g is used to drive the rotating ring 203f to move downward, and the plug-in rod 203d can be pulled out of the plug-in slot 203c through the downward movement of the rotating ring 203f, so that the first screw rod 202 will not drive the fixed rod 203a to rotate when rotating, and then the angle of the main display board 104 and the auxiliary display board 204f can be adjusted by rotating the direction of the motor 201; When the angle of the main display board 104 is adjusted, the squeezing rod 402e can be driven to move. During the movement of the squeezing rod 402e, the first sliding block 402d can be driven to move on the surface of the squeezing groove 402a. The movement of the first sliding block 402d can squeeze the second spring 402c. During the movement of the first sliding block 402d, the L-shaped rod 403e can be used to move on the surface of the clamping groove 403d. Since the clamping groove 403d is arranged in an oblique shape, the clamping plate 403c can be driven to clamp the first sliding block 402d during the movement of the L-shaped rod 403e.

[0051] In summary: the main display board 104 and the auxiliary display board 204f can be adjusted to an angle of 30 degrees.

[0052] Importantly, it should be noted that the construction and arrangement of the present application shown in a number of different exemplary embodiments are only exemplary.
