[0034] like Figures 5 to 7 As shown, the switching device 2 is installed on the mounting slot 201. The switching device 2 includes a fixing block 202, on which a first sliding rod 203 is inserted for installing a connecting block 205 and an anti-detachment plate 209. The bottom end of the first sliding rod 203 is fixed with the connecting block 205, and the end of the first sliding rod 203 away from the connecting block 205 is fixed with the anti-detachment plate 209. A second spring 204 is installed between the connecting block 205 and the fixing block 202. The elastic force provided by the second spring 204 makes the connecting block 205 move away from the fixing block 202, and at the same time plays a role in shock absorption. A connecting rod assembly 213 is installed on the column 1. A slot 212 is cut on the vertical beam 102 near the connecting rod assembly 213 for locking the locking rod 219.

[0035] like Figures 5 to 7 As shown, the column 1 has a connecting block groove 210 cut at the connecting block 205. The connecting block 205 slides up and down within the connecting block groove 210. A connecting shaft 206 is fixed outside the connecting block groove 210 for connecting the mounting plate 207. The mounting plate 207 is fixed to the bottom of the connecting shaft 206. A pair of casters 208 are installed at the bottom of the mounting plate 207 for moving the warning fence. The pair is also provided for the stability of the warning fence when it moves.

[0036] like Figures 5 to 7As shown, the linkage assembly 213 includes a mounting block 224. A pair of connecting rods 214 are rotatably mounted on the mounting block 224 to drive the top head 223 to pry the anti-detachment plate 209. A fixing plate 225 is fixed to the pair of connecting rods 214 for mounting a second sliding rod 221. The second sliding rod 221 is inserted into the fixing plate 225. The mounting block 224 is fixed to the column 1. The column 1 has a pair of connecting rod grooves 211 carved at the mounting block 224 for connecting rods 214 to extend into the mounting grooves 201. The top head 223 is fixed in the connecting rod groove 211. By pressing down the other end of the connecting rod 214, the top head 223 moves upward, thus lifting the anti-detachment plate 209 upward.

[0037] like Figures 5 to 7 As shown, each of the pair of connecting rods 214 is provided with a second slide groove 216. A second slider 215 is slidably disposed in the second slide groove 216. A locking rod 219 is fixed between the pair of second sliders 215. The locking rod 219 slides in the second slide groove 216 through the second slider 215, thereby moving the locking rod 219 along the trajectory of the second slide groove 216. The locking rod 219 is locked in the locking groove 212, thereby locking the switching device 2. The locking rod 219 is fixedly connected to one end of the second slide rod 221. A third spring 220 is installed between the locking rod 219 and the fixing plate 225. The elastic force provided by the third spring 220 causes the locking rod 219 to move away from the fixing plate 225. An anti-detachment head 222 is fixed to the end of the second slide rod 221 away from the locking rod 219 to prevent the second slide rod 221 from detaching from the fixing plate 225.

[0038] like Figures 5 to 7 As shown, a push rod 217 is provided in the second slide groove 216. One end of the push rod 217 is fixedly connected to the second slider 215. The push rod 217 is used to push the second slider 215. A rotating plate 218 is rotatably installed at the end of the connecting rod 214 away from the top head 223. Pulling the end of the rotating plate 218 away from the push rod 217 will squeeze the push rod 217 to move towards the second slider 215. The push rod 217 pushes the second slider 215, causing the locking roller 219 to disengage from the locking groove 212.

[0039] Working principle: When the warning fence is not in use, it moves by the universal wheels 208 contacting the ground. First, depending on the usage scenario, the support leg 103 is replaced with one that has anti-slip nails 111 installed on the bottom, or one that has anti-slip rubber on the bottom. When replacing, simply pinch the pinch plate 108 and disengage the buckle 107 from the clip 106. Then, remove the support leg 103 and the first slider 105 from the first slide groove 104. Then, replace it with the required support leg 103, push the first slider 105 upward along the first slide groove 104, and snap the buckle 107 onto the clip 106.

[0040] Then push the warning fence to the appropriate position, and then press down on the end of the connecting rod 214 away from the top head 223. During the pressing process, the connecting rod 214 rotates around the pivot point of the mounting block 224 and the connecting rod 214, causing the top head 223 to move upward. The part of the top head 223 placed inside the mounting groove 201 presses against the anti-detachment plate 209 and moves upward. The anti-detachment plate 209 drives the connecting block 205 to move upward through the first slide rail 203. The connecting block 205 drives the bottom caster 20 through the connecting shaft 206. 8. During the upward movement and downward pressing of the connecting rod 214, the vertical beam 102 squeezes the clamping rod 219 along the movement trajectory of the second slider 215 in the second slide groove 216 and moves towards the fixed plate 225. When it moves to the clamping groove 212, the third spring 220 uses its own elasticity to push the clamping rod 219 into the clamping groove 212, and finally clamps the clamping rod 219 into the clamping groove 212. At this time, the caster wheel 208 is separated from the ground, and the support leg 103 contacts the ground to support the warning fence and stabilize the warning fence.

[0041] After construction is completed, first gently press down on the connecting rod 214 to move the clamping rod 219 out of the slot 212. Then pull the rotating plate 218 outward away from the end of the pushing rod 217, so that the end of the rotating plate 218 in contact with the pushing rod 217 pushes the pushing rod 217 to move towards the second slider 215. The pushing rod 217 pushes the clamping rod 219 towards the fixed plate 225 through the second slider 215. Then pull the connecting rod 214 upward. When the clamping rod 219 passes the slot 212, the connecting rod 214 and the rotating plate 218 can be released. Then the second spring 204 will push the connecting block 205 away from the fixed block 202 through its own elasticity, causing the caster wheel 208 to contact the ground, so that the support leg 103 is separated from the ground. Then the warning fence can be pulled up and retracted.
