The detection rotating shaft 4 drives the connecting ring 5. The connecting ring 5 drives the hook 6. The hook 6 drives the rotor 7. Thus, the lifting movement of the rotor 7 is controlled.

Then start the viscometer body 3, the detection end inside the viscometer body 3 drives the detection rotating shaft 4, the detection rotating shaft 4 drives the hook 6 through the connecting ring 5, and the hook 6 drives the rotor 7 to rotate inside the putty, thereby detecting the viscosity of the putty. At the same time, the temperature sensor 10 can detect the temperature of the putty and transmit the detection data to the inside of the viscometer body 3, so that the viscometer body 3 can obtain the viscosity of the putty according to the resistance when the rotor 7 rotates and the temperature, improving the detection accuracy.

[0042] The user can observe whether the bubble 33 at the top of the oil liquid 32 is inside the horizontal detection line 31 through the arc-shaped plexiglass 30 to detect whether the bottom plate 1 is in a horizontal state, and then rotate the rotating blocks 26 at the four corners according to the eccentric direction of the bubble 33. The rotating blocks 26 drive the adjusting screw rod 25 to rotate. While the adjusting screw rod 25 rotates, it moves up and down through the cooperation of the internal thread sleeve 24. The adjusting screw rod 25 drives the semi-circular block 27 through the rotating block 26, thereby horizontally adjusting the device.
