During the installation of the power system poles, it is necessary to install the pole number plate on the pole, and fill in the pole number address and other information on the pole on the pole number plate. When installing the pole number plate on the pole, two stainless steel strips are usually passed through the long holes at the upper and lower ends of the aluminum plate respectively, and then the stainless steel strips are wrapped around the pole. Then the two ends of each stainless steel strip are connected with a lock, and the pole number plate printed with the line name and pole number is tied to the pole with two stainless steel strips.

[0003] When the pole number plate needs to be replaced during line reconstruction, the stainless steel strip needs to be cut, the original pole number plate needs to be removed, the cut stainless steel strip needs to be pulled out and thrown away, and then two stainless steel strips need to be re-threaded through the long holes at the upper and lower ends of the new pole number plate, and then the new pole number plate needs to be tied to the pole with a lock. This method of replacing the pole number plate is not only inconvenient, but also wastes materials.

At this time, the installer can free his hands to fix and combine the fastening device, thereby achieving the convenience of sign plate installation without the need to contact others for assistance, thereby improving the convenience of installation of the pole number plate assembly.

[0018] 2. The present invention sleeves the second stainless steel belt on the outer surface of the pole, and sleeves the first hooks at both ends inside the sleeve grooves of the elastic metal plate. By turning the rotating knob, the rotating screw is rotated inside the fixed tube, and the sleeve hole pulls the fixed columns at both ends of the second stainless steel belt to tighten the second stainless steel belt on the outer surface of the pole. No other installation parts and auxiliary installation tools are required, and the installation is more convenient. There is no need for installers to carry parts and tools when climbing, thereby improving the installation efficiency of the pole number plate assembly.

[0019] 3. The present invention arranges an elastic metal plate, and through the elastic properties of the elastic metal plate itself, the elastic metal plate is fixed on the pole through a fastening device. Through the reaction force acting on the pole, the squeezing force between the plate and the fastening device and the pole is increased, thereby increasing the mutual friction between them and improving the stability of the installation of the pole number plate assembly.

[0020] 4. The clamping sleeve of the present invention is sleeved inside one of the positioning columns. By rotating the threaded cap, the second magnet is taken out from one end of the clamping sleeve. The second magnet loses magnetism with the first magnet, and the inclined surface of the conical sleeve pushes the ball toward the inside of the movable tube, squeezing the positioning column and locking the positioning column. The clamping sleeve and the positioning column cannot be separated. The more the clamping sleeve is pulled, the stronger the ball and the positioning column are, thereby achieving fixation. The pole number plate assembly can only be disassembled with the help of other tools. It is not only convenient to install, but also has a good anti-theft effect to prevent the pole number plate assembly from being disassembled by others. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] One end of the tapered sleeve 227 and the movable tube 228 is tapered, and the movable tube 228 is movably sleeved inside the tapered sleeve 227. When the positioning column 224 passes through the inside of the tapered sleeve 227 and the movable tube 228, the ball 2210 will expand outward and push the movable tube 228 to move to one side of the tapered sleeve 227. The ball 2210 and the inner wall of the tapered sleeve 227 fit each other. When the movable tube 228 drives the ball 2210 to move toward the inclined surface of the tapered sleeve 227, the tapered sleeve 227 will push the ball 2210 toward the inside of the movable tube 228, squeeze the positioning column 224, and lock the positioning column 224.

At this time, the positioning column 224 can be easily inserted into the inside of the tapered sleeve 227 and the movable tube 228 .

[0052] Working principle of the present invention: When in use, during the initial installation, the installer can directly stick the sign plate 11 to the outer surface of the pole through the adhesive surface 12 to achieve temporary fixation of the sign plate 11. At this time, the installer can free his hands to respectively sleeve the two first stainless steel bands 201 on the upper and lower ends of the sign plate 11, and fix the pole number plate assembly 1 to the outer surface of the pole through the sleeve grooves 16 at both ends of the elastic metal plate 14.
