PCT No. PCT/DE91/00982 Sec. 371 Date Jun. 16, 1993 Sec. 102(e) Date Jun. 16, 1993 PCT Filed Dec. 14, 1991 PCT Pub. No. WO92/12825 PCT Pub. Date Aug. 6, 1992.A hand-held machine tool, particularly an angle grinder, has a device housing (10) which is divided into a motor housing (11) and a handle (15) which is arranged at one end of the latter and is rotatable relative thereto. A positioning device (20) ensures that the rotatable handle (15) is fixed in different rotational positions at the motor housing (11). A simple construction of the positioning device (20) is achieved in that a central bearing neck (22) is formed on at the motor housing (11), one of the housing shells (151) of the handle (15) which is constructed from two shells being supported in an annular groove (23) provided at the bearing neck (22). The positioning device (20) has a tension band (27) which is inserted in the annular groove (23) and is fastened by its ends to the housing shell (151) and clamps around the bearing neck (22) along a portion of its circumference at the side located diametrically opposite the support point, and a clamping element (29) for applying a tensile force to the tension band (27). The other housing shell (152) is screwed to the first housing shell (151) (FIG. 2). |
