Abstract
The utility model provides a measuring device for percentage elongation after fracture of multi-specification tensile samples. The mechanical property is an important index in material detection, wherein the detection of the percentage elongation after fracture of a tensile sample troubles a detection mechanism all along due to the centering difficulty and low efficiency of the sample after fracture. The measuring device for the percentage elongation after fracture of the multi-specification tensile samples comprises a base (1), wherein one end of the base is connected with a glidingly clamping device, the other end of the base is connected with a fixedly clamping device, and a butt-joint support seat is mounted between the glidingly clamping device and the fixedly clamping device. The measuring device is used for measuring the percentage elongation after fracture of the multi-specification tensile samples.
