The invention uses the gravity of the tamping block 6 and the elasticity of the spring 10 to tamp the ground, and the stress situation of the invention is described with reference to the stress sketch shown in fig. 4. As shown in FIG. 4, the spring force of the spring 10 during deformation is F2the angle between the first link 7 and the vertical plane is theta. When the spring 10 is in the original state, as shown in fig. 2, the spring 10 is extended by pulling the first link 7 and the second link 8 to the left, and the first link 7 and the second link 8 move, the angle between the first link 7 and the vertical plane is increased. When the first connecting rod 7 or the second connecting rod 8 is loosened, the tamping block 6 descends under the gravity of the tamping block 6 and the elastic force of the spring 10, and the ground is tamped. The force of the tamping block 6 to the ground is F mg + F2And tan theta, when the tamping block 6 descends, the included angle between the first connecting rod 7 and the vertical plane gradually decreases, and tan theta tends to be infinitesimal.
