Problems solved by technology

[0003] Disadvantageous for this hand-held power tool is that, for example, socket wrenches manufactured according to European or North American industrial standards and which are inserted onto the polygonal outer receptacle will not The machine tool is loose and shakes during operation
As a result, the socket wrench can be released from the polygonal outer receptacle and therefore cannot be used reliably with the hand-held power tool.

Embodiment Construction

[0038] figure 1 A hand-held power tool 100 with a tool receptacle 150 is shown, which has a housing 110 with a handle 126 . According to one specific embodiment, hand-held power tool 100 can be connected mechanically and electrically to battery pack 130 in order to be independent of mains power supply.

[0039] Hand-held power tool 100 is designed, for example, as a cordless rotary impact driver. However, it should be pointed out that the present invention is not limited to cordless rotary impact drivers, but can be used in different power tools, such as screwdrivers, drill drivers, impact drills, etc., regardless of whether the power tool can be used It is irrelevant for grid-dependent drive via battery pack or grid-dependent drive. In addition, it should be pointed out that the invention is not restricted to motor-driven hand-held power tools, but can generally be used in tools for which tool receptacle 150 is used.

Abstract

The invention relates to a hand-held machine tool provided with a driven shaft (124). A tool accommodating device (150) provided with a polygonal inner accommodating device (290) and a polygonal outer accommodating device (210) are arranged on the driven shaft. The tool accommodating device is provided with at least one penetrating opening (325). A locking member (360) penetrates the penetrating opening in a matched locking position to fit into the polygonal inner accommodating device (290) so that a plug-in tool (410) arranged in the polygonal inner accommodating device (290) is locked. In order to fix the locking member (360) into the at least one penetrating opening (325), at least one fixing piece (350) capable of having a at least locally elastic deformation is provided, the fixing piece cannot move in an axial direction and is arranged on the polygonal outer accommodating device (210) without a relative rotation.

Description

technical field [0001] The invention relates to a hand-held power tool with a driven shaft on which a tool holder with a polygonal inner receptacle and a polygonal outer receptacle is arranged, the tool holder having at least one through-opening, locking In an associated locking position, the element engages through the through-opening into the polygonal inner receptacle in order to lock a plug-in tool arranged in the polygonal inner receptacle. Background technique [0002] Document WO 2011 / 104105 A1 has known such a hand-held power tool configured as a rotary impact driver, which has a tool holder comprising a 28 mm long polygonal inner holder, for example for accommodating screwdriver bits, and an 11.55 mm long Long, polygonal outer housing, eg for housing a socket wrench. Approximately in the middle of the polygonal inner receptacle passing axially through the polygonal outer receptacle, that is to say starting from the free end of the polygonal outer receptacle at inte...
