Description
Technical field
The present invention relates to the hand held power machine with driven shaft, it is equipped in polygon and is accommodated outside storing apparatus and polygon
The tool Holder of device is arranged on the driven shaft, and the tool Holder has at least one through opening, lock
Passed through in the lock position that only element is attached at one it is described through opening be cooperated in the polygon in storing apparatus so as to
Insertion tool locking in the polygon in storing apparatus will be set.
Background technique
There is the hand-held tool that rotary impact driver is configured to as one kind known to document WO2011/104105A1
Machine, with tool Holder, tool Holder includes 28mm long for example for accommodating the polygon content of screwdriver head
Receive device and 11.55mm long for example for storing apparatus outside the polygon of receiving sleeve spanner.About passing axially through
The centre of storing apparatus in the polygon of the outer storing apparatus of polygon, that is to say, that the free end of storing apparatus is opened outside polygon
Begin to be equipped at intervals with one through opening with 14mm, the locking element attached can be by this in a corresponding lock position
It is cooperated in polygon in storing apparatus through opening.
Disadvantageously for the hand held power machine, such as according to Europe or North American Industry standard manufacture and sleeve arrives
The shorter length meeting of box spanner on the outer storing apparatus of polygon due to storing apparatus outside the only polygon of 11.55mm
It loosens and shakes in hand held power machine operation.Thus box spanner can be loosened by storing apparatus outside polygon and because
This cannot be used together with the hand held power machine reliable for operationly.
Summary of the invention
Therefore the object of the present invention is to provide a kind of new hand held power machines, with tool Holder, the work
Tool storing apparatus includes storing apparatus and the outer storing apparatus of polygon in polygon, is manufactured according to Europe or North American Industry standard
And be inserted into the box spanner on the outer storing apparatus of polygon can locking and it is reliable for operation on the tool Holder
Operation.
The problem is solved by hand held power machine with driven shaft, is equipped in polygon outside storing apparatus and polygon
The tool Holder of storing apparatus is arranged on the driven shaft, and the tool Holder runs through at least one to be opened
Mouthful, the opening that runs through is passed through in the lock position that locking element is attached at one to be cooperated in the polygon in storing apparatus
So that the insertion tool locking in the polygon in storing apparatus will be arranged in.It is described in order to which the locking element to be fixed on
At least one is capable of the fixing piece of at least partially flexible deformation equipped at least one in opening, and the fixing piece is axial
It is not movable and be arranged in outside the polygon without relative rotation on storing apparatus.
Invention thus achieves a kind of hand held power machine is provided, in its tool Holder, by the way that locking is first
Part is fixed on outside polygon in the region of storing apparatus by means of the fixing piece of elastically deformable may be implemented to accommodate outside polygon
The extension of device, thus for example according to the box spanner of Europe or the manufacture of North American Industry standard can also it is safe and reliably with it is more
Shape outer storing apparatus in side is connected and can be driven.
Preferably, it is described at least one be capable of the fixing piece of at least partially flexible deformation according to the C-shaped of elastically deformable
The type structure of ring.
It is possible thereby to provide the fixing piece of robust and cost advantages.
At least one described fixing piece for capableing of at least partially flexible deformation preferably has at least one vacancy, the lock
Only element is at least partially cooperated to the sky in the lock position attached and in the unlocked position attached at one
In lacking.
It is possible thereby to not only realize the safe and reliable solid of locking element in lock position but also in unlocked position
It is fixed.
Preferably, at least one described fixing piece for capableing of at least partially flexible deformation is configured in non-loaded shape
The locking element is loaded into the lock position attached under state.
The locking element is loaded into the lock position attached it is possible thereby to be realized by simple ways and means.
According to a form of implementation, it is equipped with a locking member, is configured to realize in the non-loaded state described
At least one is capable of the locking of at least partially fixing piece of flexible deformation.
The present invention, which is achieved in, provides a kind of hand held power machine, wherein the operation in hand held power machine can be especially
In effectively prevent storing apparatus in the polygon of tool Holder be not intended to and unlock out of control.
Preferably, the locking member is allocated to an actuation member, and the actuation member is in order to discharge described at least one
A fixing piece for capableing of at least partially flexible deformation resists the bullet applied by the spring part attached by means of the locking member
Power edge refers to that the axial direction from the hand held power machine is moved in unlocked position from lock position.
It is possible thereby to realize locking member using friendly and comfortable manipulation so as to by the polygon of tool Holder
Interior storing apparatus unlock.
Preferably, the locking element is according to the type structure of locking ball.
It is possible thereby to provide simple and quality-high and inexpensive locking element.
Preferably, the locking ball has the diameter of 3.2mm or more.
It is possible thereby to provide stable and robust locking element.
According to a form of implementation, a free end for being formed in the tool Holder with it is described at least one pass through
The axial length worn between the opening central point of opening is located in the range of 11mm to 13mm.
The present invention, can according to the insertion tool that different international standards manufacture it is thus achieved that provide a kind of hand held power machine
Safely and reliably locking and run on the tool Holder of the hand held power machine.Especially for example according to Europe
Or the box spanner of North American Industry standard manufacture can be safely and reliably using the outer storing apparatus driving of polygon and according to day
The insertion tool of this standard manufacture can be driven using storing apparatus in polygon safely and reliably.
