  • the spindle nut 16 is thus moved into the closed position.
  • the latching section 64 of the catch sleeve 22 engages via a gap 65 formed on the first ball carrier face 40 between the spindle 12 and the ball carrier 26 and shifts the spring base 50 from the first position to the second position against the spring force of the second spring element 52.
  • the second groove 66 is aligned in the radial direction to the exception opening 28, so that the ball element 30 can be displaced into the second groove 66 via the inner opening 34.
  • the pretensioned spring force of the first spring element 60 automatically displaces the locking sleeve 32 from the unlocking position into the locking position, as a result of which the outer opening 36 is blocked by the locking section 56 of the locking sleeve 32.
  • the stop 58 abuts against the ring element 42 and limits the displacement of the locking sleeve 32 in the locking position. In this way, a quickly releasable and directly responding mechanical locking device 20 for interlocking locking of the catch sleeve 22 with the locking sleeve 32 via the ball element 30 can be provided.
  • a damping element 68 is arranged between the fastening section 62 and the latching section 64, against which the first ball carrier end face 40 rests in the closed position. In this way, shocks during the closing process can be dampened in a simple manner.
  • Unlocking takes place by shifting the locking sleeve 32 from the locking position into the unlocking position, whereby the outer opening 36 is released and the form fit is canceled.
  • the ball element 30 is thus at least partially displaceable via the outer opening 36.
  • the latching section 64 can be guided out of the gap 65 between the ball carrier 26 and the spindle 12, the ball element 30 being guided at least in sections over the outer opening 36.
  • the spring base 50 is displaced from the second position into the first position via the prestressing force of the second spring element 48, as a result of which the inner opening 34 is blocked. By blocking the inner opening 34 via the spring base 50, the ball element 30 is guided at least in sections over the outer opening 36 and holds the locking sleeve 32 in the unlocked position in a pretensioned state.
