[0041] When in use, the warning bar 2 is placed in a suitable position so that the rear side of the clamping head 3 corresponds to the position of the first through hole 7, and then the warning bar 2 is pushed to drive the clamping head 3 to move backward, so that the clamping head 3 enters the inner cavity of the fixed shell 4 through the first through hole 7, and at the same time, the fixed clamping head 3 will contact the fixed clamping block 504 and push the fixed clamping block 504 to move, and the fixed clamping block 504 will drive the moving part 502 to move, and the moving part 502 drives the pushing column 603 to move downward in the inner cavity of the stroke through hole 503, and the pushing column 603 will drive The control part 602 and the pressing part 601 move downward synchronously and stretch the reset spring 604. When the clamping head 3 enters the inner cavity of the fixed shell 4, the force released by the reset spring 604 after stretching will pull the control part 602 and the pressing part 601 to move in the opposite direction synchronously. The control part 602 drives the pushing column 603 to move upward in the inner cavity of the stroke through hole 503, and pushes the moving part 502 to move on the surface of the limiting column 501, so that the two fixed blocks 504 approach the direction of the clamping head 3, fix the clamping head 3, and complete the work.

[0042] To sum up: the construction site warning fence, through the coordinated use of the clamping head 3, the fixing device 5 and the control device 6, solves the problem that during the installation of the existing warning fence, the warning fence usually needs to be placed in a suitable position between the two support rods, and then the bolts need to be placed at the four corners of the warning fence and tightened with tools to fix the warning fence. The installation process is relatively cumbersome, which affects the efficiency of the installation and laying of the warning fence.
