Problems solved by technology

[0003] A disadvantage of the prior art is that the tool is relatively strongly pushed from the tool cavity into the tool holder by the corresponding user by actuating the push-in element in the form of a collision, which can cause the tool to fall out of the tool holder (Ausrutschen ) or shoot out (Herausschie?en)
This can result in damage to the tool and / or injury to the user of the hand-held power tool
Furthermore, such projections impair comfort when using such hand power tools

Embodiment approach

[0042] According to one specific embodiment, the braking element 281 has a through-opening 284 for the tool 101 at its axial end region facing away from the flange-shaped section 282 , through which the tool 101 is pushed After being inserted into the inner receptacle 210, it is held firmly in the associated tool operating position. In the region of this through-opening 284 , the detent element 281 has, as shown, a hook-shaped end region 289 , so that when the tool 101 is pushed into the through-opening 284 because the tool 101 is pushed into the inner receiving Part 210 produces braking friction on tool 101 .

[0043] The hook-shaped end region 289 is preferably made of an elastomer, in particular rubber, and is used for pushing the tool 101 into the through-opening 284 and thus into the hook-shaped end region 289 by elastic deformation. At this time, an elastic force for braking the tool 101 is generated. For this purpose, the hook-shaped end region 289 has an almost annul...

Abstract

A hand power tool (100) has a tool receiver (200) which is configured to receive a tool (101) and which has an inner receiver (210). The tool receiver (210) is provided on an associated tool housing (111), in which there is disposed a drum-type tool change magazine (120) having at least one tool chamber (199) for storing the tool (101). The tool chamber is configured to be aligned so as to be flush with the inner receiver (210) to enable the tool (101) to slide from the tool chamber (199) into the inner receiver (210) or from the inner receiver (210) into the tool chamber (199). A braking device (280) is configured to brake the tool (101) as the tool (101) slides from the tool chamber (199) into the inner receiver (210).

Description

technical field [0001] The invention relates to a hand-held power tool having a tool receptacle for receiving a tool, which has an inner receptacle and is arranged on an associated tool housing in which a drum-shaped A tool change magazine having at least one tool cavity for storing tools, the tool cavity being centrally aligned with the inner receptacle so that the tool can be pushed from the tool cavity into the inner receptacle, or from the content The receiving part is pushed into the tool cavity. Background technique [0002] From the document DE 10 2006 059 688 A1 such a hand-held power tool is known, which has a tool change magazine which is rotatably supported in an associated tool housing and has a plurality of tool change magazines with different tools. The tool chamber is rotatable about an associated axis of rotation in different tool changing positions. In these tool changing positions, one of the tool pockets is aligned centrally with the associated tool rece...
