Two fixing blocks 4 are fixedly connected to both side surfaces of the base 1. A warning sign 9 is fixedly connected to the left side surface of the fence body 301. By providing the fixing blocks 4, a fixed platform can be provided for the device, facilitating the fixing work for the staff. By providing the warning sign 9, the overall warning effect of the fence body 301 can be improved, preventing uninformed people from approaching.

[0025] The outer surface of the fence body 301 is slidably connected to the inner wall of the support column 2. Two first threaded rods 302 are rotatably connected to the inner wall of the base 1. The inner wall of each fixing block 4 is threadedly connected with a bolt 5. The bottom end of each bolt 5 passes through the fixing block 4 and extends below the fixing block 4. By providing the bolts 5, it is convenient for the staff to fix the device in a suitable position, preventing position deviation during use.

[0026] A moving block 303 is threadedly connected to the outer surface of each first threaded rod 302. The outer surface of each moving block 303 is slidably connected to the inner wall of the base 1. The upper surface of each moving block 303 is fixedly connected to the bottom surface of the support column 2. Three support frames 6 are fixedly connected to the outer surface of each support column 2. The bottom surface of each support frame 6 is slidably connected to the upper surface of the base 1. By providing the support frames 6, the stability effect at the bottom of the support column 2 can be further increased, and at the same time, a certain supporting effect can also be achieved.

[0027] A driving gear 304 is fixedly connected to the outer surface of each first threaded rod 302. Two driven gears 305 are meshed with the outer surface of each driving gear 304. A rotating shaft 306 is fixedly connected to the inner wall of each driven gear 305. A lighting lamp 8 is fixedly installed on the upper surface of each support column 2. A transparent lamp cover 7 is fixedly connected to the upper surface of each support column 2. By providing the lighting lamp 8 and the transparent lamp cover 7, the lighting lamp 8 can provide good lighting in the evening and at night, thereby improving the visibility around the fence body 301, and the transparent lamp cover 7 can play a certain protective role for the lighting lamp 8.

[0028] One end of each set of rotating shafts 306 away from each other is rotatably connected to the inner wall of the base 1. One end of each set of rotating shafts 306 close to each other is fixedly connected with a gear steering device 307. The outer surface of each gear steering device 307 is fixedly connected to the inner wall of the base 1. One end of each set of gear steering devices 307 away from each other is fixedly connected with a second threaded rod 308. One end of the two first threaded rods 302 away from each other is fixedly connected with a rotating block 10. The outer surface of each rotating block 10 is provided with anti-slip grooves 11 arranged at equal distances. By providing the rotating block 10 and the anti-slip grooves 11, it is convenient for the staff to drive the first threaded rod 302 to rotate through the rotating block 10. At the same time, the anti-slip grooves 11 can prevent the situation of slipping hands.

[0029] One end of each set of second threaded rods 308 away from each other is rotatably connected to the inner wall of the base 1. The outer surface of each second threaded rod 308 is threadedly connected with a limiting frame 309. The outer surface of each limiting frame 309 is slidably connected to the inner wall of the base 1.

By providing the bearing 12, the stability of the first threaded rod 302 during rotation can be further improved, so that it can rotate stably and smoothly.

[0030] The working principle of the present utility model is as follows: When in use, the staff turns on the power supply of the lighting lamp 8 to enable it to be in a stable energized state. Then, the staff fixes the base 1 of the device at a suitable protective position through four bolts 5. When the installation work of the fence body 301 needs to be carried out, first, the staff inserts the fence body 301 into the inside of the base 1, and manually rotates the first threaded rod 302 through the rotating block 10. The rotation of the first threaded rod 302 can drive the moving block 303 on the surface to move. During the movement of the moving block 303, the support column 2 on the surface can be driven to move until the two support columns 2 can move to firmly clamp and fix the fence body 301. At the same time, when the first threaded rod 302 rotates, the driving gear 304 on the surface can be driven to rotate. The rotation of the driving gear 304 can drive the two driven gears 305 and the rotating shaft 306 to rotate. When the rotating shaft 306 rotates, one end of the gear steering device 307 can be driven to rotate. When one end of the gear steering device 307 rotates, the other end and the second threaded rod 308 can be driven to rotate. The rotation of the second threaded rod 308 can drive the limiting frame 309 on the surface to move until the limiting frame 309 moves into the inside of the fence body 301, so as to complete the fixed installation work of the fence body 301. Under the action of the four limiting frames 309, the fence body 301 can be firmly fixed inside the base 1 to avoid separation during use. The lighting lamp 8 can provide good lighting in the evening and at night, thereby improving the visual effect around the fence body 301.
