Clamp for tensile test

The utility model discloses a clamp for tensile test, which comprises frame bodies, a clamping mechanism and a telescopic piece, the two frame bodies are telescopically fixed through the telescopic piece, and the clamping mechanism is mounted on the frame bodies; the clamping mechanism comprises a first clamping block, a second clamping block, a rod body and a stop block, the first clamping block is fixedly connected with the stop block through the rod body, the second clamping block slides on the rod body, and an abutting part is arranged between the second clamping block and the stop block; the abutting part can abut the second clamping block and the check block outwards at the same time, so that the first clamping block and the second clamping block get close to each other for clamping. According to the scheme, the two abutting pieces are connected through the telescopic connecting object, the driving part is used for driving the connecting object, and therefore it is guaranteed that force exerted by the t
