Then, the adjustment telescopic rod 102 is started to adjust the position of the pressurized top plate 106, and the hollow transmission gear 105 is driven to rotate by starting the pressurization motor 104. When the hollow transmission gear 105 rotates, it drives the pressurization rod 103 to slide in the pressurization top plate 106, and adjusts the height of the pressurization rod 103 so that the bottom of the pressurization rod 103 cooperates with the top of the shock absorber.

Then, the corresponding first drive motor 209 is started to rotate, driving the arc adjustment plate 206 to slide and adjust the lifting angle of the arc barrier plate 203. Then, the second drive motor 211 is started to drive the annular detection plate 204 to rotate on the detection chassis 202, and drive the wheels to roll on the annular detection plate 204 to detect the shock-absorbing effect of the shock-absorbing structure, and the impact force received by the shock-absorbing structure is detected by the impact detection plate 208, and the resetting of the shock-absorbing structure is detected by the first pressure detection rod 108 and the pressure detection plate 205.

[0031] When testing the shock absorber alone, the bottom of the shock absorber is placed on the top of the second pressure testing rod 210, the side of the shock absorber is clamped by the clamping claw 302, and the inclination angle of the shock absorber is adjusted as needed. At the same time, the top of the shock absorber is clamped by the pressure rod 103. During testing, the rise and compression of the pressure top plate 106 are controlled by the telescopic rod between the first bracket 101 and the supporting connecting rod 201 to test the working condition of the shock absorber.
