A pulling rod 9 is connected to the outer wall of the fixed bracket 1 for rotation, and one end of the pulling rod 9 is connected to a limiting block 11 which is connected to the outer wall of the telescopic bracket 2 for sliding movement. When the display stand is not needed for displaying items, in order to improve the effect of folding and storing the base and to improve the effect of convenient carrying of the base, the second driving motor 4 can be turned on to drive the threaded rod 6 to rotate through the rotation of the bevel gear set 5. The rotation of the threaded rod 6 drives the sliding rod 7 to slide along the sliding groove 8. The sliding of the sliding rod 7 drives the pulling rod 9 to rotate through the rotation of the swing rod 10. The rotation of the pulling rod 9 drives the limiting block 11 to slide along the outer wall of the limiting groove 12, thereby folding the telescopic bracket 2, and realizing the control operation of improving the storage and display effect of the display stand at different positions when the display stand is not needed for displaying items.

[0025] Specifically, a slide groove 8 is provided at the connection portion between the outer wall of the fixed bracket 1 and the sliding rod 7, and two groups of pulling rods 9 and swinging rods 10 are provided. The position distribution of the two groups of pulling rods 9 is symmetrical about the central axis of the fixed bracket 1. The sliding rod 7 forms a sliding structure with the slide groove 8 through the threaded rod 6. The rotation of the threaded rod 6 drives the sliding rod 7 to slide along the outer wall of the slide groove 8, thereby realizing the control operation of rotating the pulling rod 9 and the swinging rod 10.

[0026] Specifically, a limiting groove 12 is provided at the connection portion between the outer wall of the telescopic bracket 2 and the limiting block 11. The limiting block 11 forms a sliding structure with the limiting groove 12 through the pulling rod 9 and the swinging rod 10. The rotation of the pulling rod 9 and the swinging rod 10 drives the limiting block 11 to slide along the outer wall of the limiting groove 12, thereby driving the telescopic bracket 2 to be extended and retracted, thereby realizing the control operation of improving the storage and display effect of the display stand at different positions when the display stand is not needed to display the items.

[0027] Embodiment 2:

[0028] refer to Figure 1 , Figure 2 and Figure 4 As shown, the outer wall of the fixed bracket 1 is fixedly connected with a fixing block 13, the bottom of the display stand body 3 is fixedly connected with a connecting block 14, the inner wall of the fixing block 13 is threadedly connected with a clamping block 17, and the connecting portion between the inner wall of the fixing block 13 and the clamping block 17 is provided with an internal thread 16, and the outer wall of the clamping block 17 is provided with an external thread 15 threadedly connected with the inner wall of the internal thread 16. When the display stand is not needed to display items, in order to improve the convenience of disassembly of the display stand and improve the convenience of carrying the display stand, the clamping block 17 can be rotated through the threaded connection between the internal thread 16 and the external thread 15, so that the clamping block 17 does not contact the surface of the connecting block 14, and then the display stand body 3 is pulled out, so that the clamping block 17 slides out of the card slot 18, so as to realize the control operation of improving the convenience of disassembly of the display stand when the display stand is not needed to display items.

[0029] Specifically, the outer wall profile of the snap-fit ​​block 17 is in a "T" shape, and two groups of snap-fit ​​blocks 17 are provided. The position distribution of the two groups of snap-fit ​​blocks 17 is symmetrical about the central axis of the display stand main body 3. By symmetrically distributing the position distribution of the two groups of snap-fit ​​blocks 17 about the central axis of the display stand main body 3, a control operation to improve the connection stability between the display stand main body 3 and the bracket is achieved.

[0030] Specifically, a slot 18 is provided at the connection portion between the outer wall of the connecting block 14 and the locking block 17. The locking block 17 forms a sliding structure between the connecting block 14 and the slot 18. Pulling out the connecting block 14 drives the locking block 17 to slide out of the slot 18, thereby realizing the control operation of convenient disassembly of the display stand body 3.

[0031] Specifically, the length of the slot 18 is greater than the length of the locking block 17, and the length of the cross section of one end of the locking block 17 is greater than the width of the cross section of the slot 18. By setting the length of the slot 18 to be greater than the length of the locking block 17, the locking block 17 can slide along the outer wall of the slot 18. By setting the length of the cross section of one end of the locking block 17 to be greater than the width of the cross section of the slot 18, the locking block 17 can be engaged with the outer wall of the slot 18.

[0032] Working principle: First, when the display stand is not needed to display items, in order to improve the effect of folding and storing the base and to improve the effect of convenient carrying of the base, the second drive motor 4 can be turned on to drive the threaded rod 6 to rotate through the rotation of the bevel gear set 5. The rotation of the threaded rod 6 drives the slide bar 7 to slide along the slide groove 8. The sliding of the slide bar 7 drives the pull rod 9 to rotate through the rotation of the swing rod 10. The rotation of the pull rod 9 drives the limit block 11 to slide along the outer wall of the limit groove 12, which plays a role in folding the telescopic bracket 2, and realizes the control operation of improving the storage and display effect of the display stand at different positions when the display stand is not needed to display items.

[0033] Finally, when the display stand is no longer needed for displaying items, in order to improve the convenience of disassembling the display stand and the convenience of carrying the display stand, the snap block 17 can be rotated through the threaded connection between the internal thread 16 and the external thread 15, so that the snap block 17 is not in contact with the surface of the connecting block 14, and then the display stand body 3 is pulled out to make the snap block 17 slide out of the slot 18, thereby realizing a control operation that improves the convenience of disassembling the display stand when the display stand is no longer needed for displaying items.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
