[0024] The outer surface of the support column 1 is provided with slots 2 at equal distances, and the height of the slots 2 is greater than the height of the blocks 9, and the blocks 9 are symmetrically distributed about the longitudinal center line of the connecting rod 10, so that the connecting rod 10 can be conveniently limited by the slots 2, and the height of the connecting rod 10 can be adjusted, so that the connecting rod 10 can be conveniently stored inside the support column 1;

[0025] The support rods 4 are centrally symmetrically distributed about the center of the support column 1, and there are 4 support rods 4, and the length of the support rods 4 is greater than the distance from the connecting block 3 to the bottom end of the support column 1. The support rods 4 support the fixed block 11, improve the stability of the fixed block 11, and help prevent the fixed block 11 from tipping over;

[0026] The connecting shaft 6 forms a telescopic structure inside the connecting groove 5 through the connecting spring 8, and the connecting shaft 6 and the limit block 7 are connected in a sliding manner, so that the compressed connecting spring 8 pushes the block 9 connected to the connecting shaft 6 to move, which is beneficial to the integrated movement of the device;

[0029] Working principle: According to Figure 1-3 When the sign needs to be used, the staff can first place the support column 1 at the designated position, and then push the block 9 into the connecting groove 5. The block 9 drives the connecting shaft 6 connected thereto to slide into the connecting groove 5. At the same time, the connecting spring 8 connected to the outer surface of the connecting shaft 6 is squeezed and compressed, and the connecting rod 10 is pulled upward to make the connecting rod 10 slide inside the support column 1. When the fixing block at the upper end of the connecting rod 10 is at a suitable height, the block 9 can be released, and the compressed connecting spring 8 will drive the connecting shaft 6 to move in the opposite direction, so that the connecting shaft 6 drives the block 9 to engage with the slot 2. At this time, the connecting rod 10 and the support column 1 are fixed, and then the support rod 4 is rotated to make the support rod 4 and the connecting block 3 rotate. After the support rod 4 is connected to the ground, the support column 1 can be supported, thereby improving the stability of the support column 1.

[0030] according to Figure 4-5 When the sign needs to be replaced, the staff can first rotate the operating lever 17 to separate the operating lever 17 from the positioning groove 16, then pull out the first sign 13 upwards to separate the protrusion 14 from the groove 15, and at the same time pull out the second sign 18 upwards, the second sign 18 slides with 11, then change the position of the second sign 18, and push the second sign 18 downwards to connect the protrusion 14 connected to the left end of the second sign 18 with the groove 15, and then rotate the operating lever 17 to thread the operating lever 17 with the positioning groove 16 provided on the second sign 18. At this time, the second sign 18 is replaced, and the drainage hole 12 discharges the impurities and sewage inside the fixed block 11. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
