[0024] As a technical optimization of this utility model, the side surface of the drive box 105 is rotatably connected to a rotary joint 107, and the side surface of the rotary joint 107 is fixedly connected to a water supply pipe, which can supply water to the inside of the drill bit and reduce dust dispersion during the drilling of granite, thus avoiding impact on the surrounding environment.
