Background
The liner of the IV-type bottle for the vehicle is made of plastic through a rotational molding process, and the plastic used in the field needs to be subjected to a tensile property test by sampling inspection due to the fact that the plastic has the characteristics of easiness in deformation and high elongation at break. In the mechanical tensile property test of the plastic liner, in order to ensure the accuracy of the tensile test result, a plastic tensile sample is clamped in the middle of a clamp, and a gauge length section is completely vertical to the end face of the clamp, so that the plastic is only subjected to axial tensile force and does not have transverse shear force in the tensile test, but in the actual tensile test, the requirement is difficult to meet through the manual operation of a tester. And the national standard GB/T1040.2 stipulates that the width of the clamping end part of the plastic tensile sample is 20mm, and the width of the clamping tool of the tensile testing machine is 45mm (the width is larger than the width of the clamping end part of the sample). Therefore, through manual operation, the existing clamp cannot clamp the plastic sample in the middle of the clamp, so that the clamping end of the plastic sample is stressed unevenly, and further transverse shearing force can be generated; meanwhile, if the scale distance section of the plastic sample cannot be perpendicular to the fixture tool, a transverse shearing force is generated, and the test result is influenced.
