Shock absorber detection instrument

The utility model belongs to the technical field of shock absorbers, and particularly relates to a shock absorber detection instrument, which comprises a bottom plate, a lifting structure is fixedly mounted at the top of the bottom plate and comprises a motor supporting sleeve, a servo motor is fixedly sleeved with an inner cavity of the motor supporting sleeve, a motor shaft is fixedly sleeved with one end of an output shaft of the servo motor, and the other end of the output shaft of the servo motor is fixedly sleeved with a rotating shaft. The two sides of the outer surface of the motor shaft are fixedly sleeved with first special-shaped connecting rods. Through the lifting structure, a servo motor is started to enable a motor shaft and a first special-shaped connecting rod to rotate, so that a second special-shaped connecting rod is pulled to rotate around the motor shaft, and due to the fact that a first limiting rod limits the second special-shaped connecting rod, one end of the second special-shaped co
