Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Embodiment: As shown in Figures 1 to 7, a lifting and quick-release device for a liquid crystal display includes a support frame 2 fixed to the base 1, a swivel frame 3 whose rear end is fixed to the support frame 2, and the front end of the swivel frame 3 is pivotally connected The lifting device 4, the rear end of the slewing frame 3 is inserted into the corresponding groove of the support frame 2 and is screwed and fixed with the support frame 2.

The rear end of the slewing frame 3 is fixed to the support frame 2 through the vertically downward screws 5. When assembling and disassembling the liquid crystal display support, it is only necessary to tighten and loosen the screws 5 connecting the two and the support frame 2 can be easily connected. Assemble or separate with the swivel frame 3.
