Tension testing device

The utility model discloses a tension testing device, including support piece, guide piece, drive piece and detection piece, guide piece set up in the one end of support piece, drive piece slide connection guide piece, the detection piece is located the other end of support piece, the input end of detection piece is connected tubular product, drive piece drives tubular product to move relative to detection piece. Through cooperation of the supporting piece, the guiding piece, the driving piece and the detecting piece, the pipe is placed on the driving piece, meanwhile, the pipe is connected with the input end of the detecting piece, the driving piece drives the pipe to start to move along the guiding piece, at the moment, the detecting piece outputs pulling force generated by the driving piece on the pipe, and when the maximum pulling force which the pipe can bear is reached, the pipe is detected. And the detection piece stops outputting the tension data and keeps the peak display of the tension, so that the
