When the device is accidentally touched and causes the computer case inside to vibrate, the vibration force of the computer case drives the support plate 15 to squeeze the plurality of circular shock-absorbing rubber blocks 14. The elasticity of the circular shock-absorbing rubber blocks 14 can achieve the effect of flexible shock-absorbing, isolation and force unloading protection during vibration, thereby reducing the hard shock impact force transmitted to the computer case, thereby reducing the risk of damage.
