Improved vibrating viscometer

An improved vibrating viscometer comprises a fixed part, a vibrating elastic piece, a distance sensor and a second driving device, the distance sensor is located on the fixed part close to the free end between the fixed end and the free end of the vibrating elastic piece, and when the free end of the vibrating elastic piece approaches the distance sensor by a preset displacement, the distance sensor is triggered to change the working state, and the second driving device drives the vibrating elastic piece to rotate. An electric signal is sent; the driving device comprises a driving circuit and a driving main body, and the driving circuit provides a predetermined resonant frequency signal for the driving main body; the temperature detection device is used for detecting the temperature of the detected sample, the second driving device comprises a second driving circuit and a second driving main body, and the second driving circuit provides a preset second resonant frequency signal for the second driving main bod
