The top of the assembly box one 3 and the assembly box two 4 is provided with a cover 5, and the bottom of the assembly box one 3, the assembly box two 4 and the cover 5 is provided with a buffer pad 8.

[0031] Specifically, each acceleration sensor 11 is located in the assembly box one 3 and the assembly box two 4, the assembly box one 3 and the assembly box two 4 are the same in structure, and the main difference is that the assembly box one 3 is located at the bottom end of the protective cover 2, and the assembly box two 4 is located above the assembly box one 3, wherein the buffer pad 8 is arranged inside to prevent the acceleration sensor 11 from being damaged and affecting the vibration force detection during the vibration work.
