Functional area 28,30,92,94.But it is also contemplated that, instrument holding element 16 has the shape different from the quantity of two
The sealed space 26,86 of shape.Clamping element 24 is configured to the latch plate of latch plate, particularly annular.Here, along at least basic
On observed parallel to the direction that extends of axis of movement 18 of instrument holding element 16, clamping element 24 is arranged on matrix 52 and instrument
Between holding element 16.Clamping element 24 is provided for, and the holding element 88,90 of toolroom machine separator 12 is being arranged at shape
Loaded in the state of in the sealed space 26,86 of shape by spring force towards the direction of instrument holding element 16.Holding element 88,90 points
Not Ju You taper shaping ingress area and fixing groove 96,98.Fixing groove 96,98 is respectively arranged to, in order to which toolroom machine is divided
Be fixed on from the shape sealed of device 12 functional area 28 on instrument coupling device 10 and with shape sealed space 26,86,30,
92nd, the corresponding collective effect in 94.The functional area 28,30,92,94 in shape sealed space 26,86 is respectively configured to circle
Shape space, the circular void is set stackedly.Here, the circular void has mutually different diameter respectively.But
Seem significant other configurations, example for those skilled in the art it is contemplated that functional area 28,30,92,94 has
Such as it is configured to the groove being tapered.Here, a part for the groove is configured to import feature region, and the gradually change of the groove
Thin part is configured to keep functional area.
In order that toolroom machine separator 12 is coupled with instrument coupling device 10, toolroom machine separator 12 is along at least base
The direction extended in sheet parallel to the rotation axis 36 of driving element 34 is placed in the reception space of instrument receiving element 66.
Before this, instrument holding element 16 by the manipulation of operating element 32 come against the spring force of spring element 20 from instrument fixed bit
Put and moved in instrument coupling position.Thus, the functional area for being configured to import feature region in shape sealed space 26,86
28th, 92 is stacked with one of two importing spaces of instrument receiving element 66 respectively.But it is also contemplated that, merely due to keeping
The importing of the taper ingress area of element 88,90 and cause the rotation of the instrument holding element 16 and thus make holding element
88th, 90 importing and the manipulation of operating element 32 are decoupled.
In addition, holding element 88,90 imported into by the importing space of instrument receiving element 66 shape sealed space 26,
86 are respectively configured in the functional area 28,92 in import feature region, so that toolroom machine separator 12 couples dress with instrument
Put 10 couplings.Toolroom machine separator 12 is so moved towards the direction of instrument coupling device 10, until pilot unit 42 is rested against
On instrument receiving element 66.And then, due to eliminating the manipulation force being applied on operating element 32, instrument holding element 16
Rotated to by spring force with about 15 ° of angle value relative to matrix 52 in instrument fixed position.Thus, by corresponding shape
The functional area 30,94 for being configured to fixing function region in sealed space 26,86 is directed respectively into corresponding fixing groove 96,98
In.In addition, being extended by clamping element 24 with spring force along the rotation axis 36 at least substantially parallel to driving element 34
Direction load the holding element 88,90.Thus, toolroom machine separator 12 is fixed on instrument coupling device 10.
During processing workpiece the torque that acts on by means of holding element 88,90 and shape sealed space 26,86 collective effect and/or by
Supported in the collective effect of instrument receiving element 66 and pilot unit 42.In addition, being fixed on work in toolroom machine separator 12
In the state of having on coupling device 10, cutting rod section and the driving element 34 of cutting rod 40 coordinate, to drive the cutting rod 40.
