Then, the fixed clamping piece 19 and the movable clamping piece 20 on the locking type connecting mechanism 5 are used to connect the connecting leg 3 with the fence frame 6 between the two adjacent vertical fences. Then, the concrete, concrete blocks or fillers for increasing the weight of the base filled in the counterweight filling cavity 11 on both sides of the counterweight base 1 are used to increase the overall weight of the counterweight base 1, so that the telescopic leg extension frame 2 and the connecting leg 3 are pressed and fixed by the counterweight base 1, thereby stably supporting the temporary construction fence.

[0044] Moreover, according to the unevenness of the construction ground, the leg screw cap 12 can be used to drive the connecting leg 3 to rotate in the leg hinge seat 4 at the bottom, thereby flexibly adjusting the vertical arrangement position of the locking type connecting mechanism 5 threadedly connected on the connecting leg 3, so as to reduce the influence of the terrain on the arrangement of each vertical fence and improve the overall aesthetics. Meanwhile, when the height of the construction fence is high and it is necessary to set an inclined support rod between the leg structure and the fence, the inclined support rod positioning connecting frame 7 can be positioned and placed in the positioning frame fixed connecting groove 8 on the upper side of the middle part of the counterweight base 1. Then, the inclined support rod connecting slide block hinged at the lower end of the inclined support rod is installed in the inclined support rod sliding clamping groove 48 through the wide mouth 49 of the slide block, and the position of the inclined support rod connecting slide block is fixed by the clamping of the clamping protrusion on the inclined support rod connecting slide block and the slide block positioning clamping hole 50 at the corresponding position, thereby facilitating the adjustment of the support angle of the inclined support rod.

[0045] In addition, when the temporary construction fender needs to be removed and disassembled, the connection between the locking type connecting mechanism 5 and the vertical fender is loosened, then the construction personnel moves the connecting leg 3 downward to fold and store the connecting leg 3 back into the leg storage slot 13 of the telescopic leg extension frame 2, and the horizontal storage position of the connecting leg 3 is stably positioned through the cooperation and clamping of the leg folding positioning clamping block 25 outside the leg hinge seat 4 at the lower end of the connecting leg 3 and the hinge seat horizontal positioning clamping slot 40 on the leg folding guide block 16. Subsequently, the telescopic leg extension frame 2, the folded connecting leg 3 and the locking type connecting mechanism 5 rotating to the lateral position thereon are completely stored into the extension frame telescopic insertion slot 9 and the connecting mechanism storage cavity 10 of the counterweight base 1; thereby facilitating the use, handling, storage and transportation of the entire leg counterweight structure.
