The working principle of the hydraulic pump with the damping effect is adopted;

in a normal state, as shown in fig. 1 and 2, when the hydraulic pump body 20 vibrates, the horizontal spring 28 and the vertical spring 24 perform double shock absorption in the horizontal direction and the vertical direction, and the shock absorption effect is good;

with continuous use, the elastic force of the horizontal spring 28 and the vertical spring 24 is lost, and at the moment, the vertical adjusting plate 21 is close to the lower support base 11, the front and rear support plates 27 on the front side and the rear support plates 27 on the rear side are synchronously close to each other front and rear, so that the lost elastic force can be reduced, the replacement of the springs is reduced, and the cost is saved;

meanwhile, the damping effect is best only when the elastic forces of the horizontal spring 28 and the vertical spring 24 are at proper strengths, so that the elastic forces of the horizontal spring 28 and the vertical spring 24 are at proper strengths by adjusting the distance between the vertical adjusting plate 21 and the lower support base 11 and the distance between the front and rear support plates 27 at the front side and the front and rear support plates 27 at the rear side, and the damping effect is improved.
