Since the material of the pressure-sensitive paper 20 is relatively soft, in order to ensure that the pressure-sensitive paper 20 will not fall during the test, the pressure-sensitive paper 20 placed on the lower pressure head 16 needs to have a certain width (Y-axis direction) to ensure that it can be placed On the lower pressure head 16. Usually, the width of the pressure-sensitive paper 20 placed on the lower pressure head 16 is about 30 mm, so that the two sides of the pressure-sensitive paper 20 can hang down on both sides of the lower pressure head, that is, rely on the pressure-sensitive paper 20 to maintain it on the lower pressure head 16 to prevent the pressure-sensitive paper 20 from falling off. In fact, since the width of the indentation is equal to the width of the upper indenter, the width of the indentation is only about 2mm.
