In this embodiment, the handle bar 1 is engaged with the lock sleeve 81. When the rod 1 is pressed down, the lock sleeve 81 can be driven to be pressed down. Specifically, the joint 12 at the end of the handle 1 has a hinge shaft 121, the hinge shaft 121 abuts against the lock sleeve 81, and when the hinge shaft 121 is fitted to the panel 2, the hinge shaft 121 has an up-down movable space so that it can press down the lock sleeve 81.

In this embodiment, a sliding groove 203 may also be formed on the panel 2 for providing the sliding portion 4442 to improve the stability of the sliding portion 442 during sliding.

As shown in fig. 20 to 26, in the present embodiment, the movable portions 54 are provided on both sides of the panel 2 in the longitudinal direction so that both sides of the mop 3 in the longitudinal direction thereof are fixed.

As shown in fig. 27 to 29, in some embodiments, the movable parts 54 are provided at both sides of the width direction of the panel 2 so that the mops 3 are fixed at both sides thereof in the width direction. The basic structure in this embodiment is the same as that in the fourth embodiment. In contrast, the present embodiment does not require the sliding portion, but directly drives the movable portion 54 through the actuating portion 441. Specifically, the actuating portion 441 includes a button 4411, the button 4411 has a pushing surface 44111, and the movable portion 54 has an inclined surface 543, and when the button 4411 is pressed, the pushing surface 44111 acts on the inclined surface 543 to push the movable portion 54 to slide, so that the movable portion 54 is opened relative to the panel 2.

The basic structures of the locking unit 7 and the releasing unit 8 in this embodiment are the same as those in the fourth embodiment, and will not be described here again.

The foregoing description of the utility model is merely exemplary of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions, without departing from the scope of the utility model as defined in the accompanying claims.
