The invention discloses a shockproof drilling tool. The shockproof drilling tool comprises a damping module and a main body module, wherein the damping module comprises a workbench, fixing pieces and a mounting shell, the fixing pieces are mounted on both sides of the workbench, the mounting shell is mounted on the workbench, and a hydraulic pump is placed in the mounting shell; and the main body module comprises an upper fixing shell and a lower fixing shell, the upper fixing shell and the lower fixing shell are movably connected, a square opening is formed in the workbench, and the main body module penetrates through the square opening. According to the shockproof drilling tool, continuous power can be effectively provided, so that the drilling slope can reach a certain angle; after well drilling is completed, the hydraulic pump is turned off, the deflecting angle can be stopped, and a flexible short joint automatically returns to the closed state under the action of pressure, so that the tripping time can
