The invention relates to a melt physical property measurement probe suspension device. The device comprises a bidirectional hook and a measuring rod device. The upper and lower parts of the bidirectional hook have the same structures and gaps of the two hooks form a right angle of 90 degrees. The measuring rod device comprises a heat insulation rod, a connection rod and a molybdenum head. The bottom end of the connection rod is connected to the molybdenum head made of high quality metal molybdenum through screw threads and the other end of the connection rod is connected to the heat insulation rod made of phenolic plastic in the same way. Through the bidirectional hook, movable connection of the top of the heat insulation rod and the bottom of a speed regulation rotator motor is kept. The device guarantees that a viscosity measurement rod is always in a vertical downward state in operation. The melt physical property measurement rod prepared from high quality metal molybdenum and phenolic plastic has high corrosion resistance and good thermal insulation performances and greatly improves accuracy of a melt physical property experiment.
