A rotatable rear hand grip (3) is releasably locked at a desired rotational position by operation of a control lever member (4). The power hand tool includes: a tool body (1) including an engine for generating driving power used for performing work; a front hand grip (2) fixed to the tool body; a rear hand grip including: a control lever member coupled to the engine for controlling an output of the engine; a supporting mechanism for supporting the rear hand grip rotationally about an axis (AX) between the tool body and the rear hand grip; a locking mechanism for locking the rear hand grip at one rotational position about the axis in response to the control lever member; and a controlling mechanism (4d) for allowing the control lever member to control the output of the engine after the locking mechanism locks the rear hand grip.

The invention claimed is: 1. A power hand tool comprising a tool body including: a driving power source for generating a driving power used for performing predetermined work;a front hand grip fixed to the tool body;a rear hand grip including: a control lever member coupled to the driving power source for controlling an output of the driving power source;supporting means for rotationally supporting the rear hand grip with respect to the tool body;locking means provided at the rear hand grip and the tool body for locking the rear hand grip at one of predetermined rotational positions relative to the tool body; andcontrolling means for allowing the control lever member to control the output of the driving power source when the locking means locks the rear hand grip, whereinthe locking means is actuated by the control lever member to lock the rear hand grip relatively to the tool body, and whereinthe controlling means comprises an elongated hole at the control lever member and an anti-plucking member, coupled to the driving power source with a wire, slidably fitted in the elongated hole so as to allow the control lever member to control the output of the driving power source when the locking means locks the rear hand grip relatively to the tool body.
