Claim:
A handsaw frame for holding a saw blade, comprising: a handle for mounting an end of a saw blade, the handle having a coupling portion; an extension bar having a first end with a coupling portion pivotally coupled to the coupling portion of the handle for allowing turning of the extension bar relative to the handle between a received position and an extended position, and a second end; and a blade-retaining arm pivoted to the second end of the extension bar and turnable about the axis of the second end of the extension bar for mounting of an opposite end of the saw blade mounted to the handle when the extension bar is in the extended position; wherein the second end of the extension bar has a recessed hole in which a spring member and a retaining member are received; the blade-retaining arm has a receiving hole in which a sliding block contacting the retaining member is inserted and slidable between a first position where the retaining member partially protrudes into the receiving hole of the blade-retaining arm such that the blade-retaining arm is prohibited from turning relative to the extension bar, and a second position where the retaining member is totally received in the recessed hole of the extension bar such that the blade-retaining arm is turnable relative to the extension bar.
