[0002] Extended vise is one of the commonly used tools for clamping and moving work such as high-temperature manufacturing and high-temperature testing. With the development of science and technology and the advancement of technology, people have an increasing demand for extended vise.

[0003] The high temperature viscosity test device is mainly used to heat the sample to be tested in a crucible to a molten state, and then test the high temperature viscosity of the sample. The highest temperature can reach 1600℃, and the general operating temperature is around 1300℃.

[0004] Most extended vises are made of carbon steel, which often causes severe oxidation during high-temperature operations, resulting in decreased tensile strength and other properties, and reduced safety; ordinary extended vises do not have a positioning function, and it is difficult to find the correct position to move high-temperature objects; the handle of existing extended vises is integrated with the body of the vise, and the thermal conductivity of steel is high, resulting in high temperature of the handle when moving high-temperature objects, which poses a risk of scalding people; existing extended vises require two hands to move high-temperature crucibles, and have a certain torsional force, and the contact area between the pliers and the crucible is small, the stability is poor, and there is a risk of the crucible slipping and the melt splashing, which is low in safety. For this reason, we have designed an extended multifunctional vise for high-temperature viscosity testing devices that can be quickly positioned, moved with one hand, and is safe and reliable.
