A hand-held machine tool is disclosed. The tool has an electric motor and an output shaft which can be driven by the electric motor about a working axis. The output shaft has an intake space which is open on the output side for receiving a machine tool and which has two elongated holes cutting into the intake space in the radial direction. Blocking elements lie in the elongated holes and protrude into the intake space and are movable between an end on the output side of the elongated hole and an end on the drive side of the elongated hole. The blocking elements abut on a radial stop in the radial direction and are forced into the intake space in an engaging manner. The stop overlaps in a locked position with the ends on the output side of the elongated holes and can be moved in the withdrawal direction against a spring force of a spring for releasing a radial movement of the blocking elements from the engagement with the intake space. A second spring includes a support ring, two bows protruding from the support ring in the withdrawal direction and bent around the intake space in the form of a segment of a circle, and a pin engaging radially from each bow in the withdrawal direction in front of the blocking element into the elongated hole.

An electric screwdriver is disclosed. The screwdriver has a spindle, a locking body, a radial stop, a strap, and a spring. The spindle defines a receiving area and an oblong hole which is open into the receiving area in a radial direction. The locking body is disposed in the oblong hole, where the locking body is protrudable into the receiving area. The radial stop is engageable with the locking body where, when the radial stop engages with the locking body, the locking body protrudes into the receiving area. A first end of the strap engages behind the locking body on a drive end. The spring is disposed between a second end of the strap and the radial stop.

In one embodiment, a method of filling a container with a liquid drug from a drug reservoir may include: a) connecting a container and a drug reservoir with a cannula such that the drug reservoir and the container fluidically communicate with each other via the cannula, while being hermetically sealed; b) reducing a first volume contained within the container to displace a gaseous medium from the first volume of the container via the cannula into a second volume contained within the drug reservoir; c) increasing the first volume of the container to displace the liquid drug from the second volume of the drug reservoir into the first volume of the container to fill the container; and d) disconnecting the container and the drug reservoir. Before performing action d), action b) and action c) can be successively performed more than once to stepwise increase an amount of liquid drug displaced.

The present invention relates to a reciprocating saw tool () having a motor drive () with a reciprocating driver () for a tool () and having a mass equilibrating body (). In addition, a device () is provided, which serves to convert a rotary movement of the motor drive () into a reciprocating movement of the reciprocating driver () along a first movement axis () and an opposite reciprocating movement of the mass equilibrating body () along a second movement axis (). For improving the sawing performance, the mass equilibrating body () is guided at an angle &#x3b1; to the reciprocating driver () so that its movement axis () is constantly at an angle to the movement axis () of the reciprocating driver ().
