The outside of the pole is covered with a fluorescent shell.

The pole is also provided with a hook for connecting the fence.

Compared with the prior art, the beneficial effects achieved by the utility model are:

1. The pole and the support base adopt an integral connection structure, no assembly is required, and it can be used at any time, which solves the technical problem of inconvenient access and disassembly of the safety fence in the prior art;

2. The retractable ground needle is set up, which can carry out auxiliary reinforcement of the fence according to the actual site needs, and improve the stability of the fence;

3. A monitoring and alarm device is added to the pole, which can warn illegal intruders and improve the restraint of the safety fence;

4. The wireless transmission module is set up, which can realize remote monitoring and facilitate the supervision and management of the staff;

5. The outside of the pole is covered with a fluorescent shell, which can still play a good warning role even in an environment with poor light.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

As shown in Fig. 1 , it is a structural schematic diagram of the utility model under the use state, including several surrounding rod assemblies, and fences are connected between adjacent surrounding rod assemblies. The surrounding rod assembly includes: a vertical rod and a supporting base arranged at the bottom of the vertical rod. In order to prevent the seine from falling off, a hook for connecting the seine is respectively provided at the upper and lower ends of the pole. The support base includes: support claws, spokes, retractable ground pins, guide sleeves and movable sleeves. There should be no less than three supporting claws, which are evenly distributed in an umbrella shape around the vertical pole, and the spokes and supporting claws are set in one-to-one correspondence. The retractable ground pin includes: a pin and a handle for telescopic control of the pin. The lower end of the pole is provided with a pin accommodating cavity, and the side wall of the pin accommodating cavity is provided with a guide groove for the handle to slide up and down, the upper end of the pin is connected with the handle, and the lower tip of the pin penetrates the guide sleeve Extend straight down. The guide sleeve is set on the lower end of the vertical rod, and is fixedly connected with the vertical rod, and the movable sleeve is arranged above the guide sleeve, and is slidably connected with the vertical rod up and down. The upper end of the supporting claw is hinged with the movable sleeve, the middle part of the supporting claw is hinged with one end of the spoke, and the other end of the spoke is hinged with the guide sleeve.
