Then, place the car drive shaft to be tested into the V-groove 4. Start the electric sliders 7 again, allowing the elastic cloth 9 to contact the car drive shaft and initially fix it. After the car drive shaft is placed, start the motor 16. The motor 16 will drive the first gear 17 to rotate, which in turn drives the second gear 18. The second gear 18 will drive the screw rod 19 to rotate, causing the connecting piece 20 to move closer to the motor 16. Simultaneously, the connecting piece 20 will move the measuring column 12. The measuring column 12 will move until the fixing piece 22 contacts the car drive shaft. The fixing piece 22 will then fix the car drive shaft again, and the fixing piece 22 will cause the pressing piece 21 to press the spring 23. The spring 23 will compress, causing the contact head 14 to touch the car drive shaft. The testing table 11 will record the data. The motor 16 will then reverse, returning the device to its initial position, ending the test.
