The locking process is simple:
Pull → Rotate → Position → Release → Lock
When the operator pulls the handle, the locking pin retracts against the spring force. The handle can then be rotated through the cam mechanism to change or temporarily hold its position. When returned to the locking position, the spring pushes the plunger back into the corresponding hole or locking point. This design makes it suitable for equipment requiring frequent adjustment without completely removing the locking pin.
