         3 . An airjet spinning unit according to  claim 1 , wherein a magnet ( 22 ) is arranged on the spindle-shaped component ( 15 ). 
     
     
         4 . An airjet spinning unit according to  claim 1 , wherein the airjet spinning unit ( 1 ) comprises a cylindrical holding fixture ( 20 ) for the spindle-shaped component ( 15 ), said spindle-shaped component ( 15 ) being movable along said holding fixture ( 20 ). 
     
     
         5 . An airjet spinning unit according to  claim 1 , wherein the spindle-shaped component ( 15 ) comprises a contact surface ( 23 ) made from a magnetic material which interacts with the magnet ( 22 ). 
     
     
         6 . An airjet spinning unit according to  claim 1 , wherein a lever ( 24 ) for moving the spindle-shaped component ( 15 ) is provided. 
     
     
         7 . A spindle-shaped component for an airjet spinning unit ( 1 ) comprising a yarn withdrawal channel ( 10 ), a cylindrical sliding surface ( 21 ) for mounting in the airjet spinning unit ( 1 ) and a conically tapering spindle tip ( 18 ) which comprises an entry opening ( 17 ) of the yarn withdrawal channel ( 10 ), wherein the spindle-shaped component ( 15 ) comprises a magnetic contact surface ( 23 ) for fixing the spindle-shaped component ( 15 ) in its operating position in the airjet spinning unit ( 1 ). 
     
     
         8 . A spindle-shaped component according to  claim 7 , wherein the magnetic contact surface ( 23 ) is annular in shape. 
     
     
         9 . A spindle-shaped component according to  claim 7 , wherein the magnetic contact surface ( 23 ) is arranged concentrically to the cylindrical sliding surface ( 21 ). 
     
     
         10 . A spindle-shaped component according to  claim 7 , wherein the spindle-shaped component ( 15 ) comprises an injector channel ( 29 ) which runs into the yarn withdrawal channel ( 10 ), and also comprises a compressed air supply ( 30 ) for supplying the injector channel ( 29 ). 
     
     
         11 . A spindle-shaped component according to  claim 7 , wherein the spindle-shaped component ( 15 ) consists of three components ( 31 ,  32 ,  33 ), wherein the first component ( 31 ) comprises the cylindrical sliding surface ( 21 ), wherein a second component ( 32 ) comprises the spindle tip ( 18 ), and wherein a third component ( 33 ) comprises the magnetic contact surface ( 23 ). 
     
     
         12 . A spindle-shaped component according to  claim 11 , wherein the first component ( 31 ) is made from a synthetic material. 
     
     
         13 . A spindle-shaped component according to  claim 11 , wherein the third component ( 33 ) is a steel ring ( 33 ) fixed to the first component ( 31 ).
