[0002] Shock absorbers are devices used to reduce vibration and impact. They are usually made of materials with elastic and cushioning properties, such as rubber, polyurethane, springs, etc. Shock absorbers are widely used in various fields, such as: industrial machinery, automotive industry, construction engineering, etc.

[0003] Shock-absorbing pads need to be tested before being put into use, such as static compression test, dynamic impact test, fatigue test, temperature influence test and durability test.

[0004] For example, the patent with publication number CN213041667U specifically discloses a damping pad fatigue test device, including a base, a workbench, a crossbeam, a box, and a fixed block, wherein a motor, a reducer, a cam, a fixed block, a pressure block, a force sensor, and a counter are arranged in the box. Thus, the damping pad can be subjected to fatigue test, and a clamp is arranged to fix the damping pad so that the pressure block will not adhere to the surface when it moves.

[0005] When the above patented shock-absorbing pad fatigue test device is used, the chuck is driven to rotate along the groove end of the workbench by starting the cylinder to fix the shock-absorbing pad. However, since the chuck can only fix the shock-absorbing pad within a certain size by being pushed down by the cylinder, it is not suitable for clamping shock-absorbing pads of different sizes, which makes the shock-absorbing pad fatigue test device have certain usage limitations and difficult to meet diverse usage needs. Therefore, it is necessary to design a shock-absorbing pad test machine to solve the above problems.

[0009] Furthermore, a placement groove is provided on the workbench.

[0010] Furthermore, the quick clamp unit includes a mounting base installed at the other end of the mounting plate, a hinged rod movably installed on the mounting base, a connecting rod movably installed on the mounting base, one end of the hinged rod is movably connected to the telescopic end of the cylinder, a pressure rod is installed on the connecting rod, and the pressure strip is connected between the two groups of pressure rods.
