[0036] Based on the above arrangement of the plurality of support blocks 5 cooperating with the compression spring 6, the bottom shape of different display stands can be adapted, and the display stands with different bottom shapes can be quickly supported.

[0037] Among them, the support block 5 includes a connecting part 51 and a support part 52, the connecting part 51 is fixed with the limit sliding block 7, one end of the support part 52 is fixed with a plug block 53, the side end of the connecting part 51 is provided with a slot 5101 matched with the plug block 53, which facilitates replacement of the support part 52, and in order to ensure stable fixation between the connecting part 51 and the support part 52, a conventional bolt can be used to connect the connecting part 51 and the support part 52.

[0038] The locking mechanism comprises a limiting plate 8, a transmission block 9 and a transmission rod 10. The limiting plate 8 is horizontally slidably installed at the side end of the support 1. The specific sliding installation structure is not shown in the figure and can be achieved by using a T-shaped sliding block matched with a T-shaped sliding groove. The limiting plate 8 is provided with a groove 801 matched with the connecting part 51. The length of the groove 801 is consistent with the length of the long hole 101.

[0043] Working principle: when in use, the staff fixes the mounting seat 2 to the related processing equipment by using the conventional bolt, then places the bottom of the display stand against the upper end of the supporting block 5, and then pushes the display stand downward. The supporting block 5 can adapt to the shapes of the bottoms of different display stands in cooperation with the compression spring 6 and can ensure that the display stands with different bottom shapes are quickly supported.
