The invention relates to a multifunctional lifter for an overhead ground wire. The multifunctional lifter comprises a clamp capable of clamping a ground wire cross arm; the middle of the clamp is in vertically and rotationally connected with a screw rod of which the upper part is provided with a rotation handle; the lower end of the screw rod is connected with a ground wire hanging hook through a connector; the clamp includes a planar plate bar which can be arranged on the ground wire cross arm; one end of the planar plate bar is provided with a square clamping groove of which the opening faces inwards; the lower clamping edge of the square clamping groove is vertically and upwards provided with a clamping bolt; the upper end portion of the clamping bolt is connected with a small clamping block located in the square clamping groove; the middle of the planar plate bar of the clamp is vertically and rotationally connected with one screw rod which can move up and down on the planar plate bar, a rotation sleeve being fixed to the upper end portion of the screw rod; and one side of the rotation sleeve is horizontally connected with a rotation handle which is composed of a rotation rod. The multifunctional lifter of the invention has the advantages of simple structure and convenient operation. The multifunctional lifter can be operated by a single person, so that the overhead ground wire can be lifted, and therefore, time and labor can be saved, the working efficiency of work can be improved, and the difficulty of the work can be decreased.
