[0003] The existing thermal deformation Vicat softening point experiment is implemented using a temperature measuring instrument, which is mainly composed of a bracket, a sample rack and a test oil tank. During the test, the sample is fixed on the sample rack and placed in the test oil tank. By applying force to the sample, the thermal deformation and Vicat softening point of the sample during the uniform increase of oil temperature are measured.

[0004] However, the sample holder of the existing heat deformation Vicat softening point temperature tester usually does not have an adjustable function. Common samples are long strips and squares. Since the sizes of samples in different batches are different, the clamping effect of the sample holder cannot be adjusted according to the size of the sample, which has certain limitations. Therefore, it does not meet the existing needs. In this regard, we propose a heat deformation Vicat softening point temperature measurement auxiliary device. Utility Model Content
