摘要： A hand-held power tool, such as an electric planer or the like, comprises a mechanism for moving or forwarding the body of the tool in a straight hand path. The mechanism includes a rotary wheel or a plate attached to the tool body so that the rotary wheel or plate contacts the surface of a work piece when the tool body is placed thereon. The rotary wheel or the plate is made of a material having a high friction coefficient. A plurality of parallel grooves are formed on the surface of the rotary wheel or so that a high degree of friction occurs between the surface thereof and the surface of the work piece should the body move in a direction other than a given direction on the surface of the work piece. The rotary wheel or plate is biased toward the work piece with the biasing force applied to the rotary wheel being variable.
