[0025] The effect achieved by the entire embodiment 2 is that, by providing a moving mechanism 3, the mounting frame 1 is pushed so that the self-locking moving wheel 302 rotates on the ground, which is convenient for moving the circulating water pump body 2. Then, by providing a shock absorbing mechanism 10, when the mounting frame 1 is vibrated, the fixed plate 180 moves downward due to gravity, so that the connecting rod 150 drives the movable block 130 to slide on the support rod 110.

During use, when the mounting frame 1 is vibrated, the fixed plate 180 moves downward under gravity, so that the connecting rod 150 drives the movable block 130 to slide on the supporting rod 110. At this time, the shock-absorbing spring 120 is squeezed and begins to shrink. Under the elastic force of the shock-absorbing spring 120 and the damping action of the damper 170, it can play a role of buffering and shock reduction, so that the circulating water pump body 2 maintains a certain stability.
