Tension test device

The utility model discloses a tension test device which comprises a rack, a lifting mechanism, a driving mechanism and a detecting part. The lifting mechanism can be arranged on the rack in a vertical sliding mode. A check block and a force exerting part are arranged on a supporting frame of the lifting mechanism, a first clamp is arranged at the bottom of the supporting frame, a first clamping part is formed on the first clamp, a second clamp is arranged at the bottom of the driving mechanism, and a second clamping part is formed on the second clamp. The first clamping part clamps one end of an article to be detected, the second clamping part clamps the other end of the article to be detected, the driving mechanism drives the second clamp to move upwards, and the second clamp drives the article to be detected to move. If the two ends of the article to be detected are not separated, the lifting mechanism moves upwards till the detecting part detects that the check block reaches the preset position, and the article to be detected is judged to be qualified; if the two ends of the article to be detected are separated, the detecting part cannot detect the check block at the preset position, the article to be detected is judged to be unqualified, the consistency of detection standards is ensured, and reliability is high.
