<p>In a vibratory angle piece, consisting of a grip sleeve part (1) with drive shaft (2) mounted therein and a head sleeve part (3) which is arranged at one end of the grip sleeve part and the axis (A) of which runs at an angle to the axis (B) of the grip sleeve part and in which a percussion piston (5), caused to perform a return stroke by means of an eccentric (4) arranged at the end of the drive shaft, can be moved axially in a reciprocating manner, which percussion piston (5) has a lateral recess (8) provided at its margin (6) with a step (7) for the engagement of the eccentric and to which a working spring (9) is allocated which effects the working stroke after crossing the step and is loaded before the step is reached, the percussion piston (5), in its working stroke, imparting a blow to the end (11) of an axially movable, plunger-like vibratory tool (10) inserted into the head sleeve part, which end (11) points into the interior of the latter, and a retaining spring (12) being arranged in the head sleeve part (3), which retaining spring (12) acts on the end (11) of the vibratory tool (10) pointing into the interior of the head sleeve part, and furthermore the spring force of the retaining spring (12) which acts on the vibratory tool (10) being variable by means of an adjusting member (13), the adjusting member (13), to individually adjust the spring force of the retaining spring, is designed as a component acting solely on the retaining spring (12). …<IMAGE>… </p> |
