The invention discloses a percussion drill capable of reducing deviation for bridging punching. The percussion drill comprises an installation frame. Multiple insertion rods are inserted in the side wall of the installation frame, and the insertion rods penetrate the installation frame. Rubber suckers are fixedly connected to one ends of the insertion rods, and limiting plates are fixedly connected to the ends, away from the rubber suckers, of the insertion rods. A drilling machine is fixedly connected to the inner side wall of the installation frame, a drill bit is rotationally connected to the side, close to the rubber suckers, of the drilling machine, and a handle is fixedly connected to the side wall of the installation frame. The problems that deviation cannot be reduced, when the drill bit is put in, the drill bit may be inclined, the construction accuracy is affected, and the project quality is reduced are solved.
