Zusammenfassung:	The utility model discloses a hammer drill tool capable of achieving multi-mode switching. Wherein the drilling assembly and the hammering assembly are matched with the shell, and the gear shifting assembly and the driving motor are matched with the shell. The drilling assembly and the hammering assembly are in matched transmission with the driving motor through a transmission mechanism. The transmission mechanism comprises a transmission part, a nested gear set, a drilling driven gear and a hammering driven gear; the lower bottom surface of the hammering driven gear is higher than the upper top surface of the drilling driven gear; the distance between the lower bottom surface of the hammering driven gear and the upper top surface of the drilling driven gear is smaller than the tooth widthof the outer sleeve gear; the distance between the hammering driven gear and the drilling driven gear is smaller than the addendum circle diameter of the outer sleeve gear; the gear shifting assemblyis controlled to drive th
