[0041] The working principle of this utility model:

[0042] In use, the protective plate 3 is flipped from the rear side of the support frame 2 to the front side of the support frame 2. At the same time, the support member 6 moves along the trajectory of the inner cavity of the stroke hole 5. When the protective plate 3 reaches the appropriate position, the fixing member 7 is pressed. The fixing member 7 will push the fixing block 902 to move on the surface of the support column 901 and squeeze the return spring 903. The fixing block 902 drives the pushing block 904 and the pushing column 905 to move synchronously. The pushing column 905 drives the control linkage 1005 to rotate. The control linkage 1005 drives the L-shaped pushing plate 1003 to move on the surface of the limiting member 1004. The L-shaped pushing plate 1003 drives the control screw The rod 1002 and the control knob 1001 rotate synchronously. When the fixing member 7 enters the inner cavity of the fixing housing 8, the force released by the return spring 903 after compression will push the fixing block 902 to move in the opposite direction on the surface of the support column 901. The fixing block 902 drives the push block 904 and the push column 905 to move in the opposite direction synchronously. The push column 905 drives the control linkage 1005 to rotate in the opposite direction. The control linkage 1005 drives the L-shaped push plate 1003 to move in the opposite direction on the surface of the limit member 1004. The L-shaped push plate 1003 drives the control screw 1002 and the control knob 1001 to rotate in the opposite direction synchronously and reset, thus completing the protection.

[0043] In summary, this economic analysis display device for highway engineering, through the coordinated use of protective plate 3, fastener 7, fixing device 9, and control device 10, solves the problem that most existing conference all-in-one machines do not have the function of protecting the display screen during use. When the conference all-in-one machine needs to be moved, the display screen may be damaged by collision during the movement, which will affect the normal workflow.
