Claim Text:
1. A handheld power saw, comprising a housing; a lifting rod in said housing; a drive mechanism in said housing, said drive mechanism being connected with said lifting rod so that said lifting rod is drivable by said drive mechanism to oscillate linearly; a saw blade extending in a longitudinal direction, connected with said lifting rod and movable in an oscillating motion in said longitudinal direction, wherein said saw blade is provided with a longitudinally extending, open-ended recess in a guide region of said saw blade, said guide region inserted in said housing, and said saw blade having a retaining region protruding from said guide region of said saw blade and a T-shaped extension of said retaining region; coupling means for retaining and driving said saw blade, wherein said coupling means is located on a front end of said lifting rod and includes a clamping sleeve and said T-shaped extension of said saw blade is inserted into said clamping sleeve and clamped thereby, whereby said saw is blade is connected to said lifting rod and drivable by said drive mechanism via said lifting rod; a guide assembly for guiding said oscillating motion of said saw blade when said saw blade is connected with said lifting rod, said guide assembly comprising: wherein said pressure roller is arranged to bear on an edge of said saw blade on an opposite side of said saw blade from a cutting edge thereof when said saw blade is connected with said lifting rod, whereby said pressure roller guides said saw blade in said oscillating motion in the longitudinal direction; and wherein said pressure bolt is arranged in said longitudinally extending recess of said saw blade so as to bear on an edge of said saw blade in said longitudinally extending recess and directly guide said saw blade in said oscillating motion when said saw blade is connected with and driven by said drive mechanism via said lifting rod.
