Patent ID: 7818887

Claim:
A handheld power tool comprising: (a) a plastic housing having a handle part and another portion adjoining the handle part; (b) a linearly reciprocating tool; (c) an electric drive motor positioned in the housing and having a rotatable motor shaft that rotates around an axis that extends non-parallel, non-colinear and non-perpendicular to a direction of linear reciprocation of the tool; (d) a rotating gear positioned on the motor shaft; (e) a motion converter configured to convert rotary motion of the gear to axially linearly reciprocating motion of the tool; and (f) a metal gear box secured to, and positioned within, the housing; (i) the motion converter being positioned in the gear box; (ii) the gear box including a gear wheel therein having an eccentrically located projection which engages the motion converter; (iii) the motor shaft projecting into the gear box from the motor; (iv) a reciprocating rod projecting outwardly from the gear box at an obtuse angle to the motor shaft; (v) a slide bearing: (A) surrounding the reciprocating rod; (B) positioned in the gear box; and (C) inhibited from rotational motion in the gear box; and (vi) at least one pin positioned in the gear box, the at least one pin comprising: (A) a pin in the gear box engaging the slide bearing; and (B) a pin in the gear box limiting relative rotational motion between the slide bearing and the rod.
