[0002] As is known, the parallel frame on the cement electric pole is fixed by a hoop, and the cable is fixed by the insulator on the parallel frame. During the long-term use of the cement electric pole, the hoop on the cement electric pole is not only prone to looseness, resulting in the downward sliding of the parallel frame, but also the rusted hoop is easily washed by rainwater, leaving marks on the cement electric pole, which affects the aesthetics. In addition, when the cable between two cement electric poles is hung or hit by a fallen tree, the cement electric pole is prone to break or fall under the influence of the tensile force, thus affecting the normal power supply of the line. For this reason, we have proposed a cement pole protection device. Summary of the Invention
