The first engaging body 31 and the second engaging body 21 can be easily engaged with or disengaged from each other by the elastic force of the elastic member 7. After the first engaging member 31 and the second engaging member 21 are engaged, the elastic member 7 rebounds to apply a force to the lower connector 4 for returning. Through the resilience of elastic component 7, the block structure block of the first joint body 31 and the second joint body 21 is firm, namely the parallel direction of the hand lever 1 and the cleaning body 2 is fixed firmly, and the cleaning wringing of the cleaning body itself is convenient to store.
