The utility model discloses an electric power wiring post, ground connection stake body including hollow structure, its bottom is the toper structure, two bar through -holes have vertically respectively been seted up to the inner wall both sides of ground connection stake body, the upper and lower direction fixed mounting of bar through -hole the slide rail, the inside fixed mounting of ground connection stake body folding push rod, folding push rod upper portion is for being X type structure, the lower part is V type structure, and handing -over department of upper portion and lower part is all through pivot swing joint, the left and right sides of the last lower extreme on upper portion is all fixed and is being set up the fixture block, the fixture block cooperatees with the slide rail, and the length of fixture block is greater than the length of through -hole, the inboard fixed mounting in upper portion of folding push rod the spring, the spring is in a compressed state. Its advantage lies in: the utility model discloses simple structure, design science, back in the fixture block embedding earth can make the fixture block be the level or be close to the horizontally state, makes its and ground bonding area be greater than the cross section of ground connection stake, prevents effectively that the ground connection stake from being extracted by the unauthorized person, has guaranteed power line's safe operation.
