[0002] A mop, also known as a mop cloth, is a long-handled cleaning tool used for scrubbing floors. Sponge mops are widely used because of their strong water absorption, making them particularly suitable for clearing accumulated water. Existing sponge mops typically consist of a sponge head and a metal clip that secures the sponge head. This is typically done by drilling a hole in the metal clip and then screwing it directly onto the mop handle to secure the sponge head. However, this assembly structure requires screwing to remove and replace the sponge head, which is very inconvenient. Furthermore, existing sponge mops require manual or manual squeezing of the sponge to remove excess water, making them difficult to use. Utility Model Content

Due to the influence of the spring assembly, the locking plate returns to its original position and the positioning block is locked in the locking mouth. In summary, the corresponding relationship between the disengagement port, the locking port and the slot is controlled by toggling the movable key. When the disengagement port and the slot correspond to each other, the mounting plate can be detached to remove the cotton head. When the locking port and the slot correspond to each other, since the diameter of the locking port is smaller than the slot, the positioning block can be locked in it, and the fixed installation of the cotton head is completed. The structure is simple and the operation is convenient, which solves the technical problem that it is inconvenient to replace the sponge head of the existing sponge mop.
