- Secured device 36 assumes a locked position in the locked state and in the unlocked state, an unlocked position and that the locking position and the unlocked position on the shaft 20 are radially spaced. This is achieved by holding the ball 34 in its locked position and being able to escape inwardly when unlocked.
- the pin 120 has an external thread and the
- Longitudinal bore 56 has a matching internal thread. If the pin is screwed into the shaft 20, the ball 34 can escape inwards. As a result, the ball 34 is unlocked manually. A sleeve 30 or 30a can then be mounted. The pin 120 can then be unscrewed out of the shaft 20 until the ball 34 is pressed radially outward via the ramp 132, until the ball 34 braces the sleeve 30 or 30a. As a result, the sleeve 30 or 30a is locked manually. Preferably, the pin 120 is thereby rotated less than 360 °, which shortens the time for locking and unlocking.
- the pin 120 is rotated by approximately 180 °. This shortens the time for locking and unlocking, whereby the operation of locking or unlocking is intuitively adequately conveyed to an operator.
- a modified pin is rotatably mounted in the longitudinal bore 56 and is pressed by a torsion spring in one direction.
- a bag then has a bottom which has a varying distance to the central axis.
- Secured device by axially pressing an actuating element against the shaft or twisting of the actuating element about a longitudinal axis of the shaft from the locked to the unlocked state can be transferred.
- Unlocking position on the shaft can be radially and / or tangentially and / or axially objected.
