The invention provides a telegraph pole transportation drawing head. The telegraph pole transportation drawing head comprises a sleeve containing a pole head of a telegraph pole. After the front end face of the sleeve is closed, the bottom wall of the sleeve extends forwards to form a sliding plate. A rib plate is axially and fixedly arranged on the axial symmetric line between the outer wall of the sleeve and the sliding plate. A plurality of fixing through holes are formed in a rib plate body from front to back. When the telegraph pole transportation drawing head is implemented specifically, the fracture surface of the sliding plate is of an arc-shaped V shape, gradually shrinks and extends upwards in an inclined mode, the valley bottom of the V shape and the bottom face of the rib plate are fixedly connected into a whole, and the forefront end face of the rib plate protrudes from the front end face of the sliding plate and is of a vertical arc-shaped structure.
