Dynamic and static tensile test clamp and test method suitable for cable

The invention discloses a dynamic and static tensile test clamp suitable for a cable and a test method. The clamp comprises a T-shaped circular truncated cone, a sleeve, a frustum and a threaded locking piece, a center hole of the sleeve is a stepped hole, a threaded hole I and a threaded hole II are formed in the two ends of the center hole of the sleeve respectively, the large diameter of the threaded hole II is larger than that of the threaded hole I, and a conical unthreaded hole is formed in the middle of the center hole of the sleeve. A through hole is formed in the center of the T-shaped circular truncated cone, and the T-shaped circular truncated cone is in threaded connection with the threaded hole I; a frustum is arranged in the conical unthreaded hole, the frustum and the conical unthreaded hole are coaxial, and a through hole for an electric core of a cable to pass through is formed in the center of the frustum; the threaded locking piece is in threaded connection with the threaded hole II and use
