Embodiments of a quill stop are disclosed. The quill stop can move between an open and closed position. The quill stop has a left and a right securing member, a locking element, a right arm, a left arm, and a left arm spring. The right arm can actuate the locking element out of engagement with a locking projection so that the right securing member and the left securing member can move relative to each other and allow a rod to be inserted between them. The locking element prevents unwanted actuation of the quill stop during operation.
