    摘要： Tool holding device (1) for a turning machine, the tool holding device comprising a housing (2) and a first oscillation mechanism (5), the first oscillation mechanism (5) comprising: a tool holder (12) with an oscillator bearing (26) for holding a tool (28); an elastic element (4) between the tool holder (12) and the housing (2); a pulse spindle (10) mounted in the housing (2) and abutting the oscillator bearing (26) with a lateral surface (21), which is substantially cylindrical and interrupted by at least one irregularity (22). The at least one elastic element (4) is arranged for pushing the tool holder (12) towards the lateral surface (21) of the pulse spindle (10), so that a rotation of the pulse spindle (10) generates an oscillation in the tool holder (12) due to the irregularity (22) in the lateral surface (21) of the pulse spindle (10).

    摘要： A bit holder assembly for a rotary tool, includes a body having a shank at its rearward end and a retraction collar slidably disposed on the body. The body has a coaxial socket formed therein to allow a tool bit to be inserted thereinto and an opening formed in the body in communication with the socket. A coil spring biases the retraction collar forwardly. A retainer is held in a bottom of the opening by the retraction collar or the coil spring. A ring magnet is disposed at the forward end of the retraction collar. The retraction collar is moveable among a neutral position, a retracted position rearward of the neutral position and a forward position forward of the neutral position. In the neutral position, the retainer engages the tool bit to retain the tool bit in the socket. In the retracted position, the retraction collar compresses the coil spring and allows the retainer to retract back up the opening to disengage the retainer from the tool bit and allow removal of the tool bit from the socket. The retraction collar is configured to float forward from the neutral position to the forward position to allow the ring magnet to engage and magnetize a fastener to retain the fastener to the tool bit.
