The invention provides an insulator string pushing terminal. The insulator string pushing terminal comprises a base, a shell installed on the base, a first grasping arm, a second grasping arm and two connecting rods, wherein the shell is T-shaped and comprises a longitudinal extension portion and a horizontal extension portion, a screw-nut structure is arranged in the longitudinal extension portion, and a nut of the screw-nut structure extends out from the front part of the shell; the first grasping arm and the second grasping arm are pivotally connected with two ends of the horizontal extension portion of the shell respectively; and the two connecting rods are pivotally connected to the middle parts of the first grasping arm and the second grasping arm and the nut of the screw-nut structure. According to the invention, a motor drives a screw to rotate, the nut is driven to move along the longitudinal direction, and the connecting rods are driven so as to enable the first grasping arm and the second grasping arm to be folded or separated. The insulator string pushing terminal provided by the invention is simple in structure, stable in operation and high in efficiency.
