Claims

[Scope of Claim for Utility Model Registration] (1) A power tool in which a main body part with an operating part attached to the tip and a built-in motor for driving the part, and a grip part with a built-in power supply connected in a bendable manner,
The connecting surfaces of the main body portion and the gripping portion are each formed into an inclined surface inclined at the same angle with respect to the central axis, and both inclined surfaces are in sliding contact with each other about the respective center portions. A restricting means is provided which is relatively rotatably pivoted and limits the rotatable angular range to approximately 180 degrees in one direction from a position where the combined posture of the main body part and the grip part is a straight line. A power tool. (2) The means for pivotally connecting a pair of inclined surfaces is a ball joint in which a spherical protrusion is erected at the center of one inclined surface and fitted into a spherical recess provided at the center of the other inclined surface. Scope of claim for utility model registration (1)
Power tools listed in ). (3) The means for limiting the rotational angle range is a semicircular guide groove carved on one inclined surface around the rotation axis, and a protrusion erected on the other inclined surface at a position opposite to the guide groove. A power tool according to claim 1 or 2 of the utility model registration claim, comprising: (4) One of the main body and the grip is provided with a stop shaft that is biased to protrude from the inclined surface thereof, and the other inclined surface is provided with a stop shaft that allows the main body and the grip to bend at a required bending angle. The power tool according to any one of the preceding claims, characterized in that the power tool is provided with a fixing means that prevents relative rotation between the two when the stop shaft is inserted in the position where the stop shaft is inserted. (5) On one of the pair of inclined surfaces, a semicircular groove centered on the rotation axis and with a plurality of saw blade-shaped protrusions arranged on the bottom surface is carved, and on the other inclined surface, A click stop is formed by protrudingly providing an engaging element having elasticity that engages with the protrusion of the groove, and the bending angle of the main body part and the grip part is at a plurality of positions intermediate between the straight line and the maximum angle, The power tool according to any one of the preceding claims, characterized in that the relative rotation of the pair of inclined surfaces is restrained.
