The plate (10) is arranged in the middle of the mop frame and the shaft fixture comprises a first part (22) joined to the plate by a first hinge connection. The rotary axis of the hinge connection is parallel with the longitudinal direction of the plate. A second part of the shaft fixture is joined to the first part through a second joint, the rotary axis of which is at right-angled to the first rotary axis. The shaft fixture (20) has a lock component which locks the second joint so that the shaft can only move around the first hinge connection. |
