Boosting device and boosting method of pneumatic pistol drill

The invention relates to a force increasing device and a force increasing method of a pneumatic pistol drill, belongs to the technical field of tools, and solves the technical problems that the force applying direction of the pneumatic pistol drill is difficult to control and labor is wasted, the drilling quality is poor and the drilling efficiency is low when cabin type workpieces are drilled. The boosting device of the pneumatic pistol drill comprises a drill gun sleeve feeding assembly and a supporting structure. The first end of the supporting structure is connected with the drill gun sleeve feeding assembly, and the second end of the supporting structure supports or clamps a workpiece. The drill gun sleeve feeding assembly comprises a drill gun sleeve unit, a hoop unit and a cylindrical rack. The hoop unit is connected with the first end of the drill gun sleeve unit, the second end of the drill gun sleeve unit is screwed with the cylindrical rack, and the second end of the cylindrical rack is connected w
