Adjustable pipeline deformation rate detection apparatus

The utility model discloses an adjustable pipeline deformation rate detection apparatus and is aimed at providing a pipeline deformation rate detection apparatus applied to pipelines different in pipe diameter in different environment. The adjustable pipeline deformation rate detection apparatus comprises an adjusting screw rod, a sleeve rod and a clamping ring, wherein the adjusting screw rod and the sleeve rod form a main shaft, distance between the left end head and the right end head of the main shaft is adjusted through adjustment of screw nuts on the adjusting screw rod, the left end head and the right end head are connected with rods A and rods B, rods A and rods B are hinged onto each other movably, rods A are connected with rods B through rubber strips, and therefore a contraction function of the apparatus can be realized. Compared with the prior art, the adjustable pipeline deformation rate detection apparatus has the beneficial effects which are that the detection sizes can be adjusted and limited
