The inner clamp of the rotating tube 18 is provided with a first latch 191, and a clamping plate 192 is fixedly installed at one end of the first latch 191. A clamping groove 193 is provided at one end of the rotating tube 18 close to the clamping plate 192. The clamping plate 192 and the clamping groove 193 are used together. The clamping plate 192 and the clamping groove 193 are both cross-shaped. A first clamping ring 194 is provided on the fixed sleeve on the side of the first latch 191 away from the clamping plate 192. The first clamping ring 194 and the outer side of the protective cover 17 are provided with first fixing holes 195 distributed in an annular manner.

[0018] A plug rod 2 is fixedly installed at the bottom end of the support rod 11, and a through groove 21 is provided inside the fixing rod 1, and the plug rod 2 is movably clamped in the through groove 21. The outer sides of the plug rod 2 and the fixing rod 1 are respectively provided with evenly distributed first positioning holes 22 and second positioning holes 23, and the number of the first positioning holes 22 and the second positioning holes 23 are four, so that the height of the support rod 11 can be adjusted to a larger distance, thereby improving the scope of use; a second latch 24 is inserted into one of the first positioning holes 22 and the second positioning holes 23, and a second retaining ring 25 is provided on the outer side of the second latch 24, and a second retaining ring 25 is provided on the outer side of the fixing rod 1, and an annularly distributed second fixing holes 26 are provided on the second retaining ring 25 and the outer side of the fixing rod 1.

[0019] The outer sides of the two support rods 11 are both bonded with reflective strips 3. By providing the reflective strips 3, passing vehicles can be reminded at night, thereby reducing the probability of collision.

[0020] A square groove 4 is formed at the top of the cross bar 12 , and the gear 19 passes through the square groove 4 . By providing the square groove 4 , the gear 19 and the toothed plate 16 can be meshed, so that the movable rod 13 can be braked.

[0021] A symmetrically distributed first stabilizing hole 5 is provided at the bottom of the protective cover 17, and a second stabilizing hole 51 used in conjunction with the first stabilizing hole 5 is provided at the top of the cross bar 12.

When it moves to a suitable distance, the first latch 191 is inserted into the rotating tube 18, and the clamping plate 192 enters the clamping groove 193. Then, the fixing screw passes through the first clamping ring 194 and the first fixing hole 195 on the outside of the protective cover 17 and fixes the first clamping ring 194. Through the cross-shaped design of the clamping plate 192 and the clamping groove 193, the gear 19 can be braked, thereby The movable rod 13 is braked by the tooth plate 16 to fix the movable rod 13; the support rod 11 is pulled upward to make the insertion rod 2 rise in the through groove 21. When the insertion rod 2 rises to a suitable height and the first positioning hole 22 and the second positioning hole 23 are on the same horizontal line, the second pin 24 is passed through the first positioning hole 22 and the second positioning hole 23, and then the fixing screw is passed through the second retaining ring 25 and the second fixing hole 26 on the outside of the fixing rod 1 and the second retaining ring 25 is fixed, so that the second pin 24 can be fixed to prevent the insertion rod 2 from falling in the through groove 21.

[0025] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
