After that, the upper pad 23 located on the top of the guide tube 22 will touch the surface of the special-shaped plate 17, and then make it rotate around the insertion rod 18. During the process, the cooperating push rod 19 and the spring 20 will limit the transposition angle of the special-shaped plate 17, and finally control the special-shaped plate 17 to be inclined to the other end, so that when the next guide tube 22 moves to the intersection of the two groups of discs 12, it will move in the other direction, and after passing the special-shaped plate 17, it will be restored to the initial state, so that the positions and trajectories of the three groups of guide tubes 22 are constantly changing, so as to ensure In order to ensure that the concrete is continuously and effectively vibrated during the vibration process, insufficient or excessive local vibration caused by the continuous operation of a single vibrating rod is avoided. Before starting the operation, the user can control the air bags 40 in the three groups of outer shells 29 to expand to different degrees, so that they can become vibrating rod structures of different sizes after cooperating with the inner shell 41, so that the vibration effect can be flexibly adjusted according to the needs of different projects and adapt to concrete of different proportions and strength grades. During the specific operation, the user can first move the push plate 44 to make it retract into the slot 43, and then the user can control the inner shell 29 to rotate and control the protrusion 32 to move from one active slot 42 to another active slot 42. At this time, the first air blocking block 24 and the second air blocking block 51 are staggered, so as to just The filter element can be sealed, and then the user can inject air from the through hole 24, and then the gas will enter the vent hole 52 through the transmission tube 46 and the inner connecting tube 48. At this time, the vent hole 52 corresponds to the position of the air groove 38, and the air will enter the air bag 40 through the valve nozzle 39, and slowly drive the air bag 40 to expand.
