Pulling force test clamp

The invention provides a pulling force test clamp, in particular to a wire harness pulling force test clamp. The pulling force test clamp comprises a clamp main body, a pulling rod as well as left force arms, right force arms, a fixing head, a return spring, fixing screws, a left clamp plate and a right clamp plate, wherein the fixing head is arranged at the top of the clamp, and is screwed with a punch pin; the return spring is arranged between the pulling rod and the clamp main body; the fixing screws are arranged to fix the left force arms and the right force arms; the left clamp plate and the right clamp plate are arranged on the left force arms and the right force arms. According to the invention, tooth threads are adopted on the clamping plates of the clamp to occlude; the pulling rod adopts a reversed technology to occlude the wire harness and the clamping plates together; the clamp plates clamp the wire harness tighter when the pulling force testing machine pulls higher; pulling force testing accuracy is improved greatly; meanwhile, the pulling rod is adopted to drive the force arms, so as to greatly relieve labor intensity of operating personnel, and improve production efficiency.
