[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The present application is provided with a manual release device and a locking device in the column body, and the lock tongue part of the locking device protruding from the support column can cooperate with the baffle, etc., so as to limit and fix the support column. When the release button on the manual release device is pressed, the release button will pull the first wire core to pull the lock tongue part in the locking device into the lock tongue shell, that is, the lock tongue part protruding from the support column is retracted into the support column. In addition, when the connecting rod of the present application needs to be unfolded, the connecting rod will be separated from the column body of the support column, and the connecting rod will pull the lock tongue part through the second wire core, so that the lock tongue part is retracted into the locking device. These two methods make the outer periphery of the support column free of any blocking parts, so that the support column can move normally, and the locking device has the functions of automatic retraction and manual retraction, which is easy to use.

[0018] 2. The locking device of the present application includes a lock tongue portion with an inclined surface. When the lock tongue portion cooperates with the baffle on the fence box, the inclined surface of the lock tongue portion will abut against the baffle, thereby squeezing the lock tongue spring. When the lock tongue portion does not cooperate with the baffle, the squeezed lock tongue spring rebounds, causing the lock tongue portion to be ejected, thereby causing the baffle to block the lock tongue portion, thereby causing the support column on which the locking device is installed to be stably fixed in the fence box.

[0019] 3. The fence box of the present application includes an outer limit rod and an inner limit rod. A space for limiting the support column is formed between the outer limit rod and the inner limit rod, so that the fence box limits the support column. In addition, a protrusion is provided on the fence box of the present application, and an upper steering device is provided on the support column, so that the sleeve of the upper steering device is located between the protrusion and the inner limit rod, further fixing the support column in the fence box.

[0020] 4. The connecting rod of the present application is formed by a plurality of articulated rod groups that are unfolded into an "X" shape. The articulated rod groups form a blocking structure of the fence. The limiting cable installed at the upper end of the articulated rod group can block the upper end area of ​​the connecting rod, increasing the difficulty of climbing over the articulated rod group. In addition, the limiting cable can control the maximum unfolding length of the articulated rod group. The use of the connecting rope can make the articulated rod group more stably connected together.

[0021] 5. The present application installs an upper steering device and a lower steering device on the column of the support column. The upper steering device and the lower steering device are both rotated by the hoops installed on the column through the gap. The connecting plate connects the hoops together. In addition, the fixed plate installed on the column can support the hoops. The connecting plate cooperates with a group of connecting rods, and the fixed plate cooperates with another group of connecting rods, so that one support column can support two groups of connecting rods. Under the action of the steering device, the two groups of connecting rods are angled to surround the construction area, reducing the use of support columns, reducing the space occupied by safety fences, and making transportation more convenient.

[0022] 6. The present application relies on a base as a supporting foundation, and a first hinged rod is installed on the base, a second hinged rod is installed on the first hinged rod, and the second hinged rod is installed with the same hinge axis, so that the second hinged rod can rotate around the hinge point with the assistance of the first hinged rod, thereby enabling the support legs to have the function of unfolding and folding.
