The invention discloses a mobile ground wire pile resistant to disassembly by mistake, and relates to the field of equipment maintenance. In a conventional ground wire, a chuck at a grounding busbar may be loose and is likely to be disassembled by mistake so as to cause induced electric shock of workers. The mobile ground wire pile comprises a ground wire lock hole, a fixing base, a movable bottomplate and a foldable operating rod, wherein the fixing base comprises a mounting plate and a fixing baffle; the operating rod passes down through the mounting plate; the lower end of the operating rod is connected with the movable bottom plate; the movable bottom plate is opposite to the fixing baffle; and the operating rod is in threaded connection with the mounting plate. When the operating rodrotates, the movable bottom plate can move up and down. The top surface of the mounting plate around the operating rod is provided with a locking pin for avoiding the horizontal rotation of the operating rod. When folded, the operating rod is restricted by the locking pin in the horizontal direction and cannot be rotated, thereby achieving mechanical locking. After the ground wire is locked, a case can be avoided that the operating rod rotates so as to loosen the ground wire pile or cause manmade mistaken disassembly.
