The stirring rod 5 is rotatably connected to the limit block 6, and the stirring rod 5 is driven to rotate by the reduction motor 4, so that the stirring rod 5 is used to stir the raw materials poured into the concrete mixer body 1; the number of shock-absorbing springs 81 is two groups, and the shock-absorbing springs 81 are symmetrically installed on both sides of the connecting damping 82. The bottom end of the shock-absorbing spring 81 is fixedly connected to the top of the support rod 83.
