When the speed measuring collar on the side of the latch group 15 is engaged with the top of the gas spring body 5, the servo motor 7 is turned off. At this time, it is confirmed that the initial values ​​of the device are all zero. After confirmation, the servo motor 7 is turned on in the forward direction again. The servo motor 7 will drive the lifting plate 4 to move downward slowly. During the movement of the lifting plate 4, after it reaches the designated position, the value on the pressure sensor 19 is observed to obtain the pressure value of the gas spring body 5 at this time. The stroke detection group 17 can accurately measure the distance the lifting plate 4 moves. During the movement, the proximity sensor 22 can detect the retraction distance of the gas spring body 5. Then, the floating speed measuring group 24 can detect the retraction speed of the gas spring body 5 to ensure that the retraction speed of the gas spring body 5 meets the detection requirements. After the test is completed, the lifting plate 4 is reset and the gas spring body 5 is removed.
