It should be noted that, even though the portion of the rotating clamping cantilever 4c that is matched with the sleeve 1 is made of an elastic material, the amount of expansion caused by the elastic material is limited, as shown in fig. 5, under the elastic action of the thin-walled hanging lugs, the distance between the fixed clamping cantilever 4b and the acting point of the other fixing piece between the two side plates of the floor cleaning machine shell 300 can be adjusted with greater adaptability, and more note that, as shown in fig. 5, the axial center portion (not shown in the drawing) of the rotating clamping cantilever 4c is in transition fit with the bearing (shaft sleeve) 41, and under the action of external force, the rotating clamping cantilever 4c can be adjusted with smaller axial displacement integrally by virtue of the constraint of the transition fit of the bearing (shaft sleeve) 41, where the elastic deformation is the elastic deformation of the portion of the rotating clamping cantilever 4c that is matched with the sleeve 1, and the elastic deformation of the rotating clamping cantilever 4c that is in the axial direction of the joint cantilever 4c that is matched with the bearing (shaft sleeve) jointly. In order to facilitate the power access of the motor detachable structure 100, in the embodiment of the present utility model, referring to fig. 2, 15, 16 and 20, one of the fixing members 4 is a fixing socket 4a or a fixing clamping cantilever 4b, on which a conductive member f is disposed, and one end of the conductive member f is electrically connected to a power input end (not shown in the drawings) of the electric driving module 2, and the other end of the conductive member f is electrically connected to a power source of the floor washing machine when the corresponding fixing member 4 is detachably connected to the floor washing machine housing 300. The conductive member f is a conductive jack in this embodiment, one end of the conductive member f is electrically connected with the power input end of the electric driving module 2, which may be that one end of the conductive jack is connected with the power input port of the motor driving board in the electric driving module 2 by a wire inserting pin (not shown in the drawing), and the other end of the conductive jack may be matched with the elastic conductive member f disposed on the side plate of the floor cleaning machine casing 300, so that when the motor detachable structure 100 is installed on the side plate of the floor cleaning machine casing 300 in place, the conductive jack is electrically connected with the elastic conductive member f on the side plate of the floor cleaning machine casing 300 in a clamping manner. The arrangement of the conductive member f makes it unnecessary to cut off the transmission wire when the motor detachable structure 100 is detached, thereby further increasing the convenience of use of the motor detachable structure 100.
