When working, the reset spring 17 can be driven to contract in the clamping hole by pulling the clamping column 16, so that the reset spring 17 can drive the sliding round block 15 to slide in the display frame 1. When this step is used, when the clamping column 16 is pulled to move to a certain position, the clamping column 16 is released, so that the clamping column 16 can be restored to its original position by the elastic characteristics of the reset spring 17.

[0031] Further, such as Figure 2 and Figure 5 As shown, a handle 18 is fixed to the top of the clamping column 16; a limiting hole 19 is provided at the top of the display inner frame 2 and at a position corresponding to the clamping column 16; the bottom end of the clamping column 16 is located inside the limiting hole 19 and fits with the limiting hole 19; fastening bolts 20 are provided on both sides of the bottom end of the display outer frame 1; the ends of the fastening bolts 20 penetrate the display outer frame 1 and are threadedly connected to the display inner frame 2.

The support frame 2 is supported, so that the device can be quickly deployed and used when it is transported to a temporary site. The cooperation of the support screw 3 and the support arm 7 facilitates the quick and effective support of the display outer frame 1 and the display inner frame 2 when they are built and used, thereby improving the applicability of the device, increasing the use function of the device, and further improving the use effect of the device. When the support screw 3 needs to be rotated, the first bevel gear 11 is driven externally to rotate, thereby conveniently driving the connecting column 10 and the support screw 3 to rotate.

Through external mechanical transmission, the device can be quickly adjusted and supported even when it is inconvenient to use the power supply, thereby improving the applicability of the device when in use. By pulling the clamping column 16, the reset spring 17 can be driven to shrink in the clamping hole, thereby driving the sliding round block 15 to slide in the display outer frame 1. When this step is used, when the clamping column 16 is pulled to move to a certain position, the clamping column 16 is released to facilitate the clamping column 16 to return to its original position through the elastic characteristics of the reset spring 17. By pulling the handle 18, it drives the clamping column 16 to disengage from the limiting hole 19, thereby releasing the connection between the display outer frame 1 and the top of the display inner frame 2. By rotating the fastening bolts 20, the connection between the bottom of the display outer frame 1 and the display inner frame 2 is released, so that when the device is not in use, the display inner frame 2 can be stored inside the display outer frame 1 to reduce the floor space occupied by the device when not in use, and it is convenient to carry the device when not in use, thereby improving the use effect of the device. When the display inner frame 2 is pulled out of the display outer frame 1, the display inner frame 2 is conveniently driven to move by the moving wheels 22, thereby improving the efficiency of the device during installation and deployment. When the positions of the display outer frame 1 and the display inner frame 2 are deployed and fixed, the projection screen is installed on the deployed display outer frame 1 and the display inner frame 2 through the first mounting column 23 and the second mounting column 24, thereby facilitating the subsequent installation of the projection screen.
