The utility model relates to an improvement of a cable drawing head, which is characterized in that a plunger hole is arranged on the front end of a cavity of a hollow drawing head, a screw bolt pushing piston is arranged in the plunger hole, the cavity and the plunger hole are filled with and closed with hydraulic pressure medium, which enables a cable conductor grasping metallic press-connect-tube to be in a hydraulic cavity, the cavity is changed through screwing and pushing into the piston, enables the hydraulic medium to pressurize the section of the metallic press-connect-tube, which is inserted into the cable conductor, thereby generating the rigid deformation to grasp the cable conductor, the structural cable drawing head can be installed and used on sites without any hydraulic pressure devices, the installation and the use are convenient, and the laying of cables is very convenient, and the metallic press-connect-tube is a pressed by a non-plastic deforming force, when the drawing is finished, the recovering the disappearing of the cavity hydraulic pressure, the rigid deformation can be recovered, thereby the cable drawing head can be repeatedly used for multiple times, and the cable drawing heads are greatly saved.
