Power wire fixing device

The invention discloses a power wire fixing device, which comprises a telegraph pole, wherein a mounting frame is mounted on the side surface of the top end of the telegraph pole, a top pull frame is mounted at the top end of the telegraph pole and connected with the mounting frame, an auxiliary structure is mounted at the top end of the top pull frame, and a fixing end is detachably mounted in the mounting frame. According to the invention, T-shaped frames are selected according to the number of electric wires needing to be fixed, then the T-shaped frames are installed in sliding grooves, and one electric wire is fixed to one T-shaped frame, so that a mounting frame can be adjusted and used according to the use requirement; a positioning nut and a connecting bushing are fixed, so that the T-shaped frame can be prevented from sliding in the sliding groove; a wind blocking frame is driven by wind power to rotate in windy weather, so that the mounting pipe is driven to rotate, and circulating rotation is conduc
