To sum up, although this device can achieve the effect of convenient loading and unloading of the shock absorbing spring, there are still certain problems in use. For example, when the shock absorber is in use, although there is a shock absorbing spring, it lacks energy absorption. During the operation of the transformer, the potential energy of the vibration will continue to vibrate. Although it can prevent hard vibration and has a certain shock absorption effect, the shock absorption effect is poor. At the same time, the device lacks an external protective structure. After long-term use , the external environment is likely to cause corrosion to the shock-absorbing structure of the device, which in turn causes the shock-absorbing effect of the device to deteriorate.
