The utility model relates to a heparin precipitation state display device which comprises a handle, wherein the lower end of the handle is fixedly connected with a display board, the lower part of the handle is connected with a transmission bar, the lower end of the transmission bar is connected with an induction board, the upper end of the transmission bar is connected with a pointer, the other end of the pointer corresponds to the display board, the transmission bar is connected with the handle through a bearing and a spring, both ends of the spring are respectively fixedly arranged on the handle and the transmission bar and the handle is also connected with a fixator. The display device disclosed by the utility model has the advantages that after ethanol is added into a container, the viscosity of a solution is changed, when a cured substance is generated, the viscosity of the solution is greatly changed and thus the tangential force is also greatly changed due to the change in the viscosity. The induction board is used for sensing the change in tangential force, a transmission shaft is used for upwards transferring the tangential force change information to the pointer, the spring is connected with the transmission bar, the transmission bar rotates to a certain angle which is changed into torque under the action of the spring and the pointer rotates while the transmission bar rotates and indicates the size of the torque. The measured values are more precise.
