The present application provides a recessed groove 11 on the top surface of the mop board 1 and a through-hole 111 within the recessed groove 11, allowing the wiping structure to be mounted on the first mounting structure 112. This structure is simpler, less expensive, and facilitates demolding during the manufacturing process, thereby significantly improving production efficiency and product qualification rate. Furthermore, the present application provides two hinged joints 12 on the mop board 1, facilitating production and manufacturing, and increasing the strength of the mop board 1, thereby extending the service life of the mop board 1. The two hinged joints 12 are provided on the top surface of the mop board 1, not within the recessed groove 11, but on the top surface of the mop board 1, thereby increasing the strength of the mop board 1.

[0052] In some embodiments, the mounting frame 2 includes two mounting arms; the mop board 1 includes a middle plate and two side plates, and the two side plates are rotatably connected to both sides of the middle plate; the mounting frame 2 includes two mounting arms; the number of connecting members 3 is also two, and the two connecting members 3 are respectively connected to the two mounting arms and the corresponding side plates; the middle plate is connected to the water squeezing handle through a push rod, and the water squeezing handle can pull the middle plate upward so that the two side plates are folded relative to the middle plate to squeeze water from the wipes, and at this time the two connecting members 3 rotate on the mop board 1.
