A tool holder for coupling of rotating and striking tools with hand power tools has a coupling sleeve, a drive member connectable to a hand power tool and transmitting a drive movement, the coupling sleeve being connected with the drive member, a tool shaft provided with groove-shaped locking pockets which are closed at both sides in an axial direction, the coupling sleeve being connected with the tool shaft, elongated locking bodies which are oriented axis-parallel and engage in the locking pockets, the coupling sleeve having a longitudinal passage in which each of the locking bodies are axially displaceable and held radially immovable, a displacement sleeve which surrounds the coupling sleeve with the locking bodies and is spring-loaded in an axial direction, the displacement sleeve having an inner blocking surface which blocks a radial movement of the locking bodies, each of the locking bodies has a construction which is saddle-shaped in a longitudinal section and has two humps which have an arcuate cross-section, are spaced from one another and abut against the blocking surface, a long shaped body which is arranged at a side facing away from the humps and has a region engaging in the locking pocket and a cross-section form-lockingly corresponding to a cross-section of the locking pockets, the blocking surface of the displacement sleeve being provided with a ring groove which allows insertion of one of the humps and has a groove depth which is greater than a radial depth of the locking pockets.

The invention relates to a battery-driven screwdriver comprising a housing (12, 18) provided with a handle (14), an on/off switch (26) and, particularly, a permanently fixed rechargeable battery (40) and charge contact tongues (37) which are associated with the rechargeable battery (40). The battery-driven screwdriver is characterised in that it is safe and comfortable to use due to the on/off switch (26) being mounted in a pivotable manner and extending in a longitudinal manner over the innerside of the handle (14), said on/off switch being able to be successively interrupted and/or closed, independently from each other, during the actuation stroke of several electric circuits of the battery-driven screwdriver (10).

摘要:
A tool holder (10) is proposed for tools inserted into machines for drilling and/or percussion operation having means for rotational driving and axial locking of a tool shank which can be inserted into a tool receptacle (11) of the respective machine, wherein a plurality of axial strips (13) which project inward radially are provided for rotational driving and at least one radially lockable locking body is provided at the tool holder (10) for locking. In order to accommodate tool shanks of two grooved shank systems with different outer diameters, two axial strips (13) which are located opposite from one another and are directed inward radially are arranged at the receptacle bore (12). The axial strips (13) are guided such that they can be released outward radially, particularly in a springing manner, wherein the axial strips (13) engage in corresponding grooves (20) of the respective inserted tool shank (19) for rotational driving.

The present invention is directed to a fitting device for a machine tool (10) with a tool holder (17), in particular for a hand-guided machine tool, for receiving insertion tools. It is provided that the tool holder (17) forms a releasable sliding fit (18) with a driving tube (16). A tool holder (16) is also provided.
摘要:
A cordless screwdriver, having a housing (12, 18) equipped with a handle (14), having an in particular permanently installed rechargeable battery (40), and having a transmission (72), is particularly compact, lightweight, and strong because the transmission (72), embodied in the form of a sun-and-planet gear, is simply inserted into a hollow, cylindrical transmission housing (18) and can be secured in position in it by an axial securing plate (62); the transmission housing (18) is also provided with an internal gearing and serves as the sun gear as well as being integrated into the reinforcing structure of the cordless screwdriver (10).
