The output ends of the two telescopic rods 202 are fixedly connected to an L-shaped plate 204. A spring 203 is sleeved on the arc surface of the telescopic rod 202. The two ends of the two springs 203 are respectively fixedly connected to the fixing plate 201 and the L-shaped plate 204. An L-shaped clamping plate 205 is slidably connected to one side of the L-shaped plate 204. One side of the L-shaped clamping plate 205 is fixedly connected to the warning fence body 1. Two T-shaped grooves 208 are opened on one side of the fixing plate 201. A T-shaped block 207 is slidably connected inside the T-shaped groove 208. One side of the two T-shaped blocks 207 is fixedly connected to a limiting plate 206. One side of the limiting plate 206 is fixedly connected to the warning fence body 1. The effect is achieved that the L-shaped plate 204 moves away from the L-shaped clamping plate 205. At the same time, the spring 203 and the telescopic rod 202 are in a contracted state. After the L-shaped plate 204 completely moves away from the L-shaped clamping plate 205, the fixing plate 201 can be removed from the limiting plate 206. An internal thread ring 210 is fixedly connected to one side of the fixing plate 201. A screw rod 211 is threadedly connected inside the internal thread ring 210. The effect is achieved that the internal thread ring 210 and the screw rod 211 are adapted to each other. One end of the screw rod 211 is fixedly connected to a T-shaped block 212. The arc surface of the T-shaped block 212 is rotatably connected to the L-shaped plate 204. The effect is achieved that the rotation of the T-shaped block 212 drives the screw rod 211 to rotate. One end of the T-shaped block 212 is fixedly connected to a fixing rod 213. One end of the fixing rod 213 is fixedly connected to a rotating block 214. The effect is achieved that the rotation of the rotating block 214 drives the fixing rod 213 to rotate, causing the T-shaped block 212 to rotate. Two round rods 209 are fixedly connected to one side of the fixing plate 201. The arc surfaces of the two round rods 209 are slidably connected to the L-shaped plate 204. The effect is achieved that the round rods 209 prevent the L-shaped plate 204 from shifting in position during movement.

[0034] Referring to Figure 4 As shown in the figure, in this implementation: The protection device 3 includes two fixing frames 31. The sides of the two fixing frames 31 close to each other are fixedly connected to the warning fence body 1. Four elastic pieces 34 are fixedly connected to one side of the fixing frame 31. The effect is achieved that the elastic pieces 34 and the fixing frame 31 are fixed. One end of the four elastic pieces 34 is fixedly connected to a protection plate 35. The effect is achieved that the movement of the protection plate 35 drives the elastic pieces 34 to stretch or contract. A warning pad 36 is fixedly connected to one side of the protection plate 35. Four round blocks 33 are fixedly connected to the side of the protection plate 35 close to the fixing frame 31. The effect is achieved that the warning pad 36 and the round blocks 33 are fixed on the protection plate 35. The arc surface of the round block 33 is slidably connected to a cylinder 32. One end of the four cylinders 32 is fixedly connected to the fixing frame 31. The effect is achieved that the round block 33 slides on the cylinder 32.

[0035] Working principle: Through the connecting device 2, when assembling the warning fence is required, the operator first places the warning fence around the warning area, connects two adjacent warning fences, presses the L-shaped plate 204 in the direction close to the fixed plate 201. After the telescopic rod 202 is contracted to the maximum extent, the fixed plate 201 can be moved, so that the opened T-shaped groove 208 moves in the direction of the T-shaped block 207. When the T-shaped block 207 completely slides into the T-shaped groove 208, the pressed L-shaped plate 204 can be released. At this time, the spring 203 and the telescopic rod 202 rebound, causing the L-shaped plate 204 to move towards the L-shaped clamping plate 205, forming the assembly of two adjacent warning fences. Through the connecting device 2, it solves the problem that when assembling the traditional warning fence, it is basically connected by bolts, and it is easy to lose the bolts during assembly and difficult to find. At the same time, after the bolts are used outdoors for a period of time, they will rust, causing difficulties in disassembly.

[0036] Through the protection device 3, when protecting the warning fence is required, the operator first fixes the fixed frame 31 and the warning fence body 1. When the warning fence body 1 is collided, the warning pad 36 first receives the impact force. The warning pad 36 transmits the received impact force to the protection plate 35, and the protection plate 35 drives the elastic piece 34 to compress. The elastic force generated by the elastic piece 34 cancels out the impact force. Through the protection device 3, it solves the problem that the traditional assembled warning fence is prone to deformation after being collided.
