[0006] When the pressing plate needs to be disassembled, the insertion rod is extracted from the first connecting hole, so that the restriction on the sleeve ring is removed, and thus the rod body and the pressing plate are disassembled. Through the above arrangement, when the pressing plate or the rod body is damaged, the damaged parts can be replaced by disassembly, so that the environment is more protected. Moreover, after the rod body and the pressing plate are disassembled, more space is saved, and it is convenient to carry, package and transport.

[0007] As a preferred embodiment of the present application, the pressing plate is provided with a groove, the bottom wall of the groove is provided with a first through hole, and the first connecting blocks are fixedly connected to the bottom wall of the groove.

[0008] When encountering stubborn stains, water can be injected into the groove, and the water can flow into the PVA layer through the first through hole, thereby achieving water supply to the PVA layer. Through this setting, only a small amount of water is needed to wet the PVA layer, thereby cleaning the stubborn stains, and the mop does not need to be taken to a flushing place for flushing. According to the test, 2-3 liters of water is needed for a simple cleaning of the mop, and 0.5-1 liter of water is needed for a simple wetting of the mop, and only 0.2 liters of water is needed to wet the PVA layer through the setting.

[0010] Through this setting, when the insertion rod is pulled out, the insertion rod and the second connecting block are separated, so that the PVA layer can be disassembled. In actual production, the second connecting block can be a plastic block. When the PVA layer is damaged, the PVA layer and the second connecting block can be replaced as a whole, thereby improving the service life of the device.

[0011] As preferred in the present application, the rod body comprises an upper sub-rod, a middle sub-rod and a lower sub-rod; the middle sub-rod upper end is provided with a first threaded cavity; the upper sub-rod lower end is fixedly connected with a first threaded rod, the first threaded rod and the first threaded cavity are threadedly connected, the first threaded rod lower end is fixedly connected with an elastic cylindrical block, and the edge of the elastic cylindrical block is attached to the inner wall of the first threaded cavity; the lower sub-rod lower end is connected with the sleeve ring; the insertion rod has a cavity, and a water inlet hole and a water outlet hole which are communicated with the cavity; and the first threaded cavity is communicated with the water inlet hole through a hose.

[0012] Through this setting, water can be added to the first threaded cavity, and by rotating the first threaded rod, the water in the first threaded cavity can be squeezed into the cavity, and then into the groove through the water outlet hole. Through this setting, water can be injected into the groove at any time when needed. Moreover, through this setting, the total length of the rod body can be adjusted, thereby facilitating carrying, storage and transportation.
