    • A reciprocating saw (10) is provided having a motor oriented within a housing (14) for operably driving a saw bar (22) and blade holder (24) in a reciprocating motion. The blade holder (24) has a longitudinal slot (30) for receiving a saw blade (32), and a transverse aperture (36) extending into the longitudinal slot (30) for receiving a follower (38). A sleeve (42) is pivotally mounted upon the body (26), and has a circum-axial cam groove (46) formed therein cooperating with the follower (38). Rotation in a first lock direction urges the follower (38) into the longitudinal slot (30) for engaging the saw blade (32) and rotation of the sleeve (42) in a second unlock direction allows the follower (38) to retract. A biasing member (48) is included for biasing the sleeve (42) in the first lock direction. The sleeve central bore (44) is adapted to provide clearance for the follower (38) such that the sleeve (42) is permitted to axially translate relative to the body (26) for assembly or disassembly of the blade holder (24).

    • A power tool (10,110,210,310,402,510) having a housing (12), an electric motor disposed in the housing, and a spindle (22,122,222,328,528) drivingly attached to the electric motor. The spindle includes a cavity (24,124,224,330,530) adapted for receiving a bit (B) therein and a window (30,130,228,332,532) extending through the spindle in communication with the cavity. The power tool further has a retention device (12,112,212,312,412,512) including a bit engaging member (28,128,230,334,534) disposed within the housing and operable to extend through the window and retain a bit within the cavity. The power tool still further has an actuator (46,46',48,174,250,314,514) operable by a user externally of the housing to disengage the bit engaging member from a bit received in the cavity and, finally, a mechanical interconnection system operably coupled between the actuator and the retention device to actuate the retention device in response to the actuator, wherein the mechanical interconnection is disposed within the housing.

    • The invention relates to a device for fixing a tool holder (1), especially for driven tools, whereby said device comprises a spindle (2) having a forward-facing surface (3) and a bore (4) that intersects the forward-facing surface and extends rearward starting from said surface, and receives a shaft (5) of the tool holder (1). The device also comprises a mechanism (6) for locking the tool holder with the spindle (2), which is provided with an inner (7) and an outer (8) locking element which engage with each other. The aim of the invention is to provide an especially compact device for fixing a tool holder which allows the axial supply of media, for example cooling lubricants. For this purpose, the locking elements (7, 8) are configured in a bayonet catch manner and a projecting element (9) is disposed in a blind groove (12) which extends in a peripheral surface (11), first axially then radially, starting from a face (10).

    • Bei einem Handgerät erfolgt die Verbindung einer Mitnahmehülse (6) mit der Drehspindel (5) über kugelförmige Verriegelungselemente (7). Die Verriegelungselemente (7) greifen in Ausnehmungen (5a) an der Drehspindel (5) ein. Die Ausnehmungen (5a) weisen an der dem freien Ende der Drehspindel (5) benachbarten Seite geneigt verlaufende Auflauframpen (5b) auf. Durch das Auflaufen der sich an der Mitnahmehülse (6) abstützenden Verriegelungselemente (7) an der Auflauframpe (5b) entsteht aus dem zu übertragenden Drehmoment eine Kraftkomponente in axialer Richtung, welche die Drehspindel (5) und die Mitnahmehülse (6) an Anschlagschultern (5c), (6c) gegeneinander verspannt. Beim Aendern der Drehrichtung wird die Verbindung gelöst und durch Auflaufen der Verriegelungselemente (7) an den gegenüberliegenden Auflauframpen wiederum hergestellt.
