- the lever 24 has projections 26 which are clipped in a groove 27 of the spindle-shaped component.
- the lever 24 can be operated manually or automatically in its gripping area 28 and thereby moves the spindle-shaped component 15 parallel to the thread withdrawal channel 10.
- the lever 24 prevents at the same time that after moving away the contact surface 23 from the sphere of action of the magnets 22, the spindle-shaped member 15 by itself the cylindrical receptacle 20 of the main body 19 falls out. If it is necessary to remove the spindle-shaped component completely from the air jet spinning unit 1, the spindle-shaped component 15 can be easily clipped out of the lever 24 with its groove 27 and removed from the air jet spinning unit 1.

- the distance between the contact surface 23 and the spindle tip 18 in the region of the inlet opening 17 is important for the properties of the spun yarn 2. By changing the distance from the spindle tip 18 to the contact surface 23 can be varied, how far the spindle tip 18 in the vortex chamber 9 protrudes. Different mass can be achieved, for example, if otherwise the same dimensions only the height of the steel ring 33 is changed.
- steel rings 33 can be used with different height dimensions or it can be adjusted by a use of washers between the first component 31 and the steel ring 33, the position of the contact surface 23. This also tolerances on the spindle-shaped member 15 can be compensated. It is also possible to machine an otherwise finished spindle-shaped component 15 in a final operation on the abutment surface 23 in order to ensure an exact spacing of the spindle tip 18 from the abutment surface 23.
- the spindle component 18 containing the second component 32 is inserted via cylindrical receiving surfaces 34 in the first component 31 and fixed by a threaded pin 35.
- the receiving surfaces 34 may be associated with sealing rings 36.
