The cylinder base 12 is provided above the lateral support 4, the lower end of the cylinder base 12 is fixedly connected to the lateral support 4, and the upper end of the cylinder base 12 is fixedly connected to the lower end of the lifting cylinder 11. The upper end of the lifting cylinder 11 (referring to the end of the telescopic rod of the lifting cylinder 11) is connected to the other end of the connecting plate 9, and the number of lifting cylinders 11 is the same as the number of connecting plates 9. The telescopic rod of the lifting cylinder 11 extends to push the connecting plate 9 and the vibration head 101 upward, and the telescopic rod of the lifting cylinder 11 retracts, and the connecting plate 9 and the vibration head 101 also move downward accordingly.
