An elastic expansion component 24 and a locking component for locking the mop head base plate 21 and the supporting plate 22 are arranged between the mop head base plate 21 and the supporting plate 22; when the elastic expansion component 24 is in a natural state, the mop head base plate 21 and the supporting plate 22 are in a separated state; when the locking member locks the mop head base plate 21 and the pallet 22, the elastic expansion member 24 is in a deformed and compressed state. In the technical scheme, an elastic expansion component 24 is arranged between a drag head base plate 21 and a supporting plate 22, and the thickness of a flat drag head 2 is adjusted by controlling the deformation quantity of the elastic expansion component 24, in the specific scheme, the elastic expansion component 24 can be a spring or an elastic rubber piece, wherein when the spring is adopted, the stability of the drag head base plate 21 and the supporting plate 22 in an expansion state is required to be ensured, and the spring is used as a pressure spring in the state; when the elastic rubber piece is adopted, a hollow silica gel belt can be adopted, so that the elastic rubber piece has enough deformation. And, can lock the first base plate 21 of dragging with layer board 22 through setting up the locking part, make elasticity strut the part 24 and adjust between extrusion state and natural state, when dragging first base plate 21 and layer board 22 locking, the stability of whole flat dragging head 2 can be guaranteed, can be used to drag the ground.

In the technical scheme, a groove 25 is arranged on the end face of the mop head base plate 21, and the elastic expansion component 24 is positioned in the groove 25. When the elastic expanding component 24 is in a parallel state, the elastic expanding component 24 is completely accommodated in the groove 25, and the supporting plate 22 is pressed against the mop head base plate 21, so that the mop is more stable when mopping.

In addition, the locking part comprises a first locking part 261 and a second locking part 262 for respectively locking the two ends of the drag head 2 in the length direction; the first locking member 261 and the second locking member 262 are movably disposed on the mop head base plate 21, and the first locking member 261 and the second locking member 262 can move along the movable ends thereof and enable the free ends thereof to clamp the blade 22. In the technical scheme, as the flat dragging head 2 of the flat dragging is mostly a rectangular body, the first locking piece 261 and the second locking piece 262 are respectively arranged at the two ends of the flat dragging head 2 in the length direction; in this way, the first and second locking members 261 and 262 can stably maintain the blade 22 and the drag head base plate 21 in the locked state. In a specific embodiment, the first locking member 261 and the second locking member 262 are U-shaped locking members, one side U-shaped ends of the first locking member 261 and the second locking member 262 are hinged to the towing head base 21, and the other side U-shaped arms of the first locking member 261 and the second locking member 262 can be used for clamping the blade 22. In this embodiment, the first locking member 261 and the second locking member 262 are U-shaped locking members, which rotate along the U-shaped end of one side thereof and can lock the blade 22 by the U-shaped arm of the other side; when the blade 22 and the head base plate 21 are locked by the first locking member 261 and the second locking member 262, the blade 22 and the head base plate 21 are positioned in the U-shaped openings of the first locking member 261 and the second locking member 262.

The two longitudinal ends of the support plate 22 are provided with slopes 221, which can guide the free end engagement process of the first locking member 261 and the second locking member 262. On the basis of the scheme, the inclined surfaces 221 are arranged at two end parts in the length direction of the supporting plate 22, when external force acts on the first locking piece 261 and the second locking piece 262, the first locking piece 261 and the second locking piece 262 rotate along the U-shaped end part at one side of the first locking piece 261 and the second locking piece 262, the end part of the U-shaped arm at the other side abuts against the inclined surfaces 221 in the overturning process, further, due to the continuous action of the external force and the guiding action of the inclined surfaces 221, the supporting plate 22 is forced to be pressed to the mop head base plate 21, and the elastic expansion part 24 is continuously compressed; until the pallet 22 is pressed against the mop head base plate 21.

On the basis of the above scheme, the two ends in the length direction of the supporting plate 22 are provided with the clamping grooves for locking the first locking member 261 and the second locking member 262 at the final positions so as to maintain the supporting plate 22 and the drag head base plate 21 in the locking state, and the first locking member 261 and the second locking member 262 are placed to be loose, so that the structure of the flat drag head 2 is unstable. In addition, in order to consider that the U-shaped arm at one side of the first locking member 261 and the second locking member 262 is pressed on the front end surface of the supporting plate 22 after being turned over, although the U-shaped arm abuts against the inclined surfaces 221 at the two ends of the supporting plate 22 in the length direction, the thickness of the U-shaped arm may influence the attaching of the mop cloth 23 to the ground, so that the U-shaped arm can be properly embedded into the clamping groove to reduce the influence of the thickness on the use of the mop.

Example 2:

An elastic tensioning component 27 is arranged between the mop head base plate 21 and the supporting plate 22, and when the elastic tensioning component 27 is in a natural state, the mop head base plate 21 and the supporting plate 22 are locked and pressed; when the head base plate 21 and the pallet 22 are separated from each other, the elastic tension member 27 is in a state of tensile deformation. In the above technical solution, unlike the solution in which the elastic spreading member 24 spreads the mop head base plate 21 and the pallet 22, the solution in which the elastic tensioning member 27 tensions the mop head base plate 21 and the pallet 22 is adopted; but also, the distance between the head base plate 21 and the pallet 22, that is, the thickness of the flathead 2 is controlled by the amount of deformation of the elastic tension member 27. In this embodiment, the elastic tensioning member 27 may also be a spring or an elastic rubber member, and in this state, the spring acts as a tension spring, and the acting force of the spring tensions the head base plate 21 and the supporting plate 22; the elastic rubber piece can adopt a hollow silica gel belt to reduce the elastic limit of the elastic rubber piece and increase the deformable quantity of the elastic rubber piece. When the flat plate mop with the structure is used, an external object is cut into the space between the mop head base plate 21 and the supporting plate 22 to enable the mop head base plate 21 and the supporting plate 22 to be in a separated state, so that the purpose of adjusting the thickness of the flat mop head 2 is achieved; therefore, as shown in the figure, an opening 28 is formed between the lower end of the drag head base plate 21 in the length direction and the lower end of the supporting plate 22 in the length direction, and when in use, an external object can be cut into the space between the drag head base plate 21 and the supporting plate 22 through the opening 28, thereby having a guiding function.
