The second sliding groove extends along the preset direction so that when the part of the insert (40) outside the second mating member is inserted into the slot (30) or removed from the slot (30), the protrusion (46) is located in the second sliding groove and slides along the second sliding groove.

6. The locking mechanism according to claim 5, characterized in that, The protrusion (46) is disposed on the insert (40); a support (47) is disposed on the housing of the second mating part, the support (47) contacts the protrusion (46) to support the insert (40); wherein, when the insert (40) moves along the preset direction, the protrusion (46) moves relative to the support (47).

7. The locking mechanism according to claim 1, characterized in that, The second mating member has a mounting cavity (48) and a preset opening (481) communicating with the mounting cavity (48). At least a portion of the insert (40) extends out of or retracts into the mounting cavity (48) through the preset opening (481) to achieve at least a portion of the insert (40) extending out of or retracting into the second mating member.

8. The locking mechanism according to claim 1, characterized in that, The slot (30) or the insert (40) is disposed at the sewage discharge part of the main body (10) of the floor scrubber, and the insert (40) or the slot (30) is disposed at the sewage suction part of the base station (20).

9. The locking mechanism according to claim 1, characterized in that, The insert (40) is used to communicate with the control module of the second mating member so that the control module controls the insert (40) to switch between the original retracted state and the extended state.

10. A floor scrubbing machine device, comprising a floor scrubbing machine body (10) and a base station (20), characterized in that, The floor scrubbing machine also includes the locking mechanism as described in any one of claims 1 to 9.
