The canister turns in relation to the spindle under the action of a coil spring acting between them. The slot (19) in the arm (12) is widened at one end to form an insertion openings (20), whose clear cross-section (D) is slightly greater than the external spindle dia. Notches (21) are formed along one or both edges of the slot, in which coupling devices on the spindle (16) positively engage.</p> |
