The utility model provides a shock attenuation connection structure of dashing ware shakes, see figure 1, including bumper shock absorber urceolus 1, connecting bumper shock absorber inner tube 2 below the bumper shock absorber urceolus 1, connecting the barrel 3 that is used for placing the motor below the bumper shock absorber inner tube 2, being equipped with the mounting groove 4 that is used for placing the bumper shock absorber in bumper shock absorber urceolus 1 and the bumper shock absorber inner tube 2, the periphery of bumper shock absorber inner tube 2 is opened there is the ring channel, and the ring channel is embedded to have rubber circle 5. The shock absorber outer cylinder 1 is integrally connected or welded with more than 2 hard connecting pieces 6, the hard connecting pieces are uniformly distributed around the shock absorber outer cylinder by 360 degrees, the lower parts of the hard connecting pieces 6 longitudinally span the shock absorber inner cylinder 2, and gaps 7 are reserved between the hard connecting pieces and the shock absorber inner cylinder 2. Gap 7 makes the lower part of stereoplasm connecting piece 6 be in unsettled state, and rubber circle 5 can also play certain effect in the unsettled part can ensure the bumper shock absorber, and the bumper shock absorber is motor and the eccentric block of protection lower part, if there is not unsettled part, the vibrational force on upper portion can directly conduct the motor, leads to motor life to shorten.

The rubber ring 5 has a shock-absorbing function, but if only the rubber ring 5 is arranged, the rubber ring 5 is subjected to large longitudinal bearing force, and large impact is generated on the rubber ring 5, so that the rubber ring 5 is worn quickly. The rubber ring 5 is protected in the processes of rising and pressing down due to the fact that the hard connecting piece 6 is added, namely the vertical hard bearing is increased. In addition, hard materials have a high force conductivity, which reduces the loss of force.
