[0015] 1. A No. 1 installation mechanism, a No. 2 installation mechanism and a transmission mechanism are provided. The pin is rotated first to drive the pin out of the threaded hole. At the same time, the balls on both sides of the pin reduce the friction with the inner wall of the base. Then the column is pulled upward to make the column drive the docking block out of the docking groove. The handle is then rotated to drive the No. 2 gear to rotate. The No. 2 gear drives the No. 1 gear to rotate. Then the No. 1 gear drives the bidirectional screw rod to rotate. After the limit blocks move away from each other on the bidirectional screw rod and reach the limited position, the column is pulled to one side to make the limit block out of the limit groove. At the same time, the plug rod is out of the socket. The column and the main board can be quickly disassembled, which is convenient for the staff to disassemble and assemble the building fence, thereby improving the convenience of the building fence.

[0016] 2. A protective mechanism is provided. The connecting seat is placed on the main board, and then the connecting pin is inserted into the through hole of the main board from one side of the mounting frame. Then the fastening ring is rotatably sleeved on the connecting pin, so that the fastening ring and the connecting pin are threadedly sleeved and the position of the mounting frame is restricted. The connecting seat can be installed above the main board. When someone wants to climb over the main board, the rolling property of the protective roller makes it impossible for the climber to have a fulcrum, thereby preventing climbing and improving the practicality of the building fence.

[0027] according to Figure 1-3 As shown, the protection mechanism 4 includes a protection roller 401, a connecting seat 402, a mounting frame 403, a fastening ring 404 and a connecting pin 405. A connecting seat 402 is provided above the main board 1, and a protection roller 401 is installed above the connecting seat 402 through a bearing. Mounting frames 403 are fixed on both sides of the connecting seat 402 with intervals. Connecting pins 405 are passed through the inner sides of the mounting frames 403 and the main board 1, and a fastening ring 404 is threadedly sleeved on the outer side of the connecting pin 405. There are two protection rollers 401, and sharp blocks are distributed in an annular manner on the outer side of the protection roller 401.

[0028] In specific implementation, since most building fences are not equipped with anti-climbing structures, some outsiders may climb over the building fences to enter the construction site, causing safety accidents. The connection seat 402 can be placed on the main board 1, and then the connecting pin 405 is inserted into the through hole of the main board 1 from one side of the mounting frame 403, and then the fastening ring 404 is rotated and sleeved on the connecting pin 405, so that the fastening ring 404 and the connecting pin 405 are threadedly connected and the position of the mounting frame 403 is limited, so that the connection seat 402 can be installed above the main board 1. When someone wants to climb over the main board 1, the rolling property of the protective roller 401 makes it impossible for the climber to have a fulcrum, which can prevent climbing from occurring and improve the practicality of the building fence.

[0029] according to Figure 1-2 and Figure 4-7 As shown, the first installation mechanism 5 includes a limit groove 501, a limit block 502 and a bidirectional screw 503. The bidirectional screw 503 is installed in the built-in groove of the column 2 through a bearing. The outer thread of the bidirectional screw 503 is sleeved with the limit block 502. The limit grooves 501 are provided on both sides of the main board 1 near the limit block 502. The second installation mechanism 7 includes a docking block 701, a docking groove 702, a latch 703 and a threaded hole 704. The two ends of the base 3 are penetrated by the latch 703. The inner side of the base 3 is provided with a docking groove 702. The outer side of the column 2 near the docking groove 702 is connected to a docking Block 701, threaded holes 704 are provided on both sides of the column 2 near the pin 703, the transmission mechanism 8 includes a No. 1 gear 801, a No. 2 gear 802 and a handle 803, one end of the bidirectional screw rod 503 is fixedly sleeved with the No. 1 gear 801, one side of the No. 1 gear 801 is meshed with the No. 2 gear 802, one side of the No. 2 gear 802 is connected with the handle 803 through a transmission shaft, the cross-sectional shape of the limit block 502 and the limit groove 501 are both "L"-shaped, the top view shape of the docking block 701 and the docking groove 702 are both "T"-shaped, and balls are installed on both sides of the pin 703.

[0030] When the building fence needs to be disassembled after the construction is completed, the pin 703 can be rotated first to drive the pin 703 to disengage from the threaded hole 704. At the same time, the balls on both sides of the pin 703 reduce the friction with the inner wall of the base 3, and then the column 2 is pulled upward, so that the column 2 drives the docking block 701 to disengage from the docking groove 702, and the column 2 and the base 3 can be quickly disassembled, and then the handle 803 is rotated to make the handle 803 drive the second gear 802 to rotate, and the second gear 802 drives the first gear 801 to rotate, and then the first gear 801 drives the two-way screw rod 503 to rotate, so that the limit blocks 502 move away from each other on the two-way screw rod 503 and reach a limited position, and then the column 2 is pulled to one side to make the limit block 502 disengage from the limit groove 501, and the plug rod 6 disengages from the socket 10, so that the column 2 and the main board 1 can be quickly disassembled, which is convenient for the staff to disassemble and assemble the building fence, thereby improving the convenience of the building fence.
