The cross-section of the buffer block 14 is a convex shape, and the convex part of the buffer block 14 is located on the inner side of the support platform 4. The surface of the buffer block 14 is provided with a shock-absorbing spring 17, and the other end of the shock-absorbing spring 17 is fixed to the support On the outer surface of the support platform 4, four buffer blocks 14 are respectively arranged on the side surfaces of the support platform 4, and an adjustment structure is arranged on the surface of the buffer block 14. The adjustment structure uses a baffle 15 to adjust the sliding distance of the buffer block 14 on the surface of the support platform 4, thereby adjusting the vibration amplitude of the workbench 5. The adjustment structure includes a baffle 15, and the baffle 15 is slidably connected with the buffer block 14, and the baffle 15 passes through the surface of the buffer block 14.
