Previously, the tool holder becomes 16 by an actuation of the operating element 32 against the spring force of the spring element 20 moved from the tool fixing position to the tool coupling function. As a result, a function area designed as an insertion function area is formed in each case 28 . 92 the positive locking recesses 26 . 86 overlapping with one of two insertion recesses of the tool receiving member 66 arranged. However, it is also conceivable that solely as a result of an introduction of the conical insertion areas of the holding elements 88 . 90 a rotation of the tool holding element 16 is caused and thus introducing the retaining elements 88 . 90 decoupled from an actuation of the operating element 32 is.
  • Furthermore, the holding elements 88 . 90 to a coupling of the power tool separating device 12 with the tool coupling device 10 through the insertion recesses of the tool receiving element 66 in the respective functional area designed as an insertion function area 28 . 92 the positive locking recesses 26 . 86 introduced. The machine tool separator 12 As long as in the direction of the tool coupling device 10 moves until the guide unit 42 on the tool receiving element 66 is applied. Subsequently, the tool holding member 16 due to a cancellation of an operating force on the control 32 by the spring force in the tool fixing position by an angular extent of about 15 ° relative to the base body 52 twisted. As a result, a functional area designed as a fixing function area is formed in each case 30 . 94 the respective form-fitting recess 26 . 86 in the respective Fixierungsnut 96 . 98 introduced. In addition, the retaining elements 88 . 90 through the pressure element 24 with a spring force along at least one substantially parallel to the axis of rotation 36 of the drive element 34 running direction applied. Thus, the machine tool separator is 12 at the tool coupling device 10 fixed. In a processing of a workpiece acting torques by means of an interaction of the holding elements 88 . 90 and the form-fitting recesses 26 . 86 and / or by means of an interaction of the tool receiving element 66 and the leadership unit 42 supported. In addition, in one of the tool coupling device 10 fixed state of the power tool separating device 12 Cutting strand segments of the cutting strand 40 to a drive of the cutting strand 40 in engagement with the drive element 34 ,
