Description

Technical Field

[0001] This utility model relates to a cleaning tool, and more particularly to a combination cleaning mop. Background Technology

[0002] Flat mops are common household cleaning tools, mainly consisting of a mop handle and a mop board for wiping floors. A wiping cloth, usually flat, is attached to the bottom of the mop board. Based on the method of cloth attachment, they are divided into hook-and-loop fastener flat mops and clip-on flat mops. Hook-and-loop fastener flat mops typically use Velcro to secure the cloth, while clip-on flat mops use a clamping mechanism to hold the cloth in place.

[0003] For example, patent CN222787675U discloses a wiping part cloth clamping structure and its wiping tool, including a wiping body and a mop handle. The wiping body is the mop head of a flat mop. The top of the mop handle is hinged to the top of the mop head. The bottom of the wiping body is the wiping surface. A cloth clamping mechanism that can be unfolded or retracted is movably installed on the side of the wiping body.

[0004] Currently, flat mops on the market come in various sizes, with different sizes suitable for cleaning different places. For example, small flat mops are suitable for cleaning desktops such as desks and office desks, while large flat mops are suitable for cleaning floors in rooms, public places, stairs, and corridors. Since the size of the mop blades of conventional flat mops is fixed, multiple flat mops of different sizes are needed to clean different places. A large number of mops take up a lot of space, and tools cannot be placed in an orderly manner, which will make the place look messy. Utility Model Content

[0005] In view of the above problems, this utility model provides a combination cleaning mop.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a modular cleaning mop, including a small mop plate and a large mop plate. The small mop plate can be connected to the cleaning material for cleaning, or the small mop plate can be assembled with the large mop plate for cleaning. The small mop plate includes a first base plate and a first cover plate that can move vertically relative to the first base plate. A locking mechanism is provided between the first base plate and the first cover plate. The large mop plate includes a second base plate and a second cover plate that can move vertically relative to the second base plate. A first clamping mechanism for clamping the cleaning material is provided on the second base plate. When the second cover plate is subjected to force and moves downward or upward relative to the second base plate, the first clamping mechanism can clamp or release.

[0007] In the assembled state, the first cover plate and the second cover plate are detachably and fixedly connected, and the first base plate and the second base plate are detachably and fixedly connected. When the first cover plate and the second cover plate are subjected to downward pressure and move down relative to the first base plate and the second base plate to the closed state and are clamped by the first clamping mechanism, the locking mechanism can lock the first cover plate and the first base plate to restrict the relative movement and separation of the first cover plate and the first base plate.

[0008] A further preferred technical solution of this utility model is as follows: the first base plate is provided with a second clamping mechanism for clamping the wiping object. When the first cover plate is subjected to force and moves down or up relative to the first base plate, the second clamping mechanism can clamp or loosen. When the first cover plate moves down relative to the first base plate to the closed state and the second clamping mechanism clamps, the locking mechanism can lock the first cover plate and the first base plate to restrict the relative movement and separation of the first cover plate and the first base plate.

[0009] A further preferred technical solution of this utility model is as follows: the top of the second cover plate is provided with an assembly groove for inserting a small slide plate, the bottom of the assembly groove is provided with a through opening, the second cover plate is provided with a first connecting member for connecting the first cover plate and the second cover plate together, and the second bottom plate is provided with a second connecting member for connecting the first bottom plate and the second bottom plate together.

[0010] A further preferred technical solution of this utility model is as follows: the first connecting member is movably disposed on the second cover plate. The first connecting member is provided with a control part extending from the top of the second cover plate and an insert block extending into the assembly groove from the inner side wall of the assembly groove. The first cover plate is provided with an insertion port that cooperates with the insert block. The insert block is inserted into the insertion port to connect the first cover plate and the second cover plate together. Moving the first connecting member can cause the insert block to exit the insertion port.

[0011] A further preferred embodiment of this utility model is as follows: the second connecting member is rotatably mounted on the second base plate. A locking block is provided on one of the second connecting member and the second base plate, and a locking groove cooperating with the locking block is provided on the other. The second connecting member includes a rotary dial and a connecting post fixed on the rotary dial. The rotary dial is located at the bottom of the second base plate. The connecting post passes through the second base plate and extends into the assembly groove. A protruding locking block is provided on the side of the connecting post. A first through hole is provided on the first base plate for the connecting post to pass through. The connecting post passes through the first through hole. The second connecting member can rotate between a locking position and a releasing position.

[0012] When the second connector rotates to the engaging position, the locking block engages on the upper edge of the first through hole to prevent the connecting post from disengaging downwards from the first through hole. At this time, the locking block falls into the locking groove to lock the second connector from rotating relative to the second base plate.

[0013] When the second connector is rotated to the release position, the connecting post can move downward relative to the first base plate to disengage from the first perforation.

[0014] A further preferred embodiment of this utility model is as follows: a second spring is supported between the first cover plate and the first base plate. The second spring has an elastic force that pushes the first cover plate to move relative to the first base plate. The locking mechanism includes a locking member and a third spring disposed on the first cover plate. The locking member can move relative to the first cover plate. The locking member is provided with a first latching part. The first base plate is provided with a second latching part that cooperates with the first latching part. When the first cover plate moves down relative to the first base plate and closes, the first latching part and the second latching part form a latching connection to lock the first cover plate and the first base plate, thereby restricting the first cover plate from moving up and separating relative to the first base plate. Moving the locking member can disengage the first latching part and the second latching part from the latching connection.

[0015] A further preferred embodiment of this utility model is as follows: The first clamping mechanism includes two first clamping claws, which are arranged opposite to each other. The first clamping claws are rotatably connected to the bottom of the second base plate via a first shaft. Each first clamping claw has a first clamping part and a first mating part, which are located on both sides of the first shaft. A clamping opening is formed between the first clamping parts of the two first clamping claws. The second cover plate has a first linkage part that is linked and engaged with the first clamping claws. The first linkage part is opposite to the first mating part.

[0016] When the large sliding plate is placed on the flat surface and the second cover plate is pressed down, the second cover plate moves downward relative to the second base plate, and the first linkage part contacts the first mating part and pushes the first mating part to swing downward, causing the two first clamping parts to swing upward and clamp tightly.

[0017] When the second cover plate moves up and resets relative to the second base plate, the first linkage part moves up with the second cover plate, so that the two first clamping parts can swing downward and loosen under the action of gravity or the reset part connected to the first clamping claw.

[0018] A further preferred embodiment of this invention is as follows: The second clamping mechanism includes two second clamping claws, which are arranged opposite to each other. The second clamping claws are rotatably connected to the bottom of the first base plate via a second shaft. Each second clamping claw has a second clamping part and a second mating part, which are located on both sides of the second shaft. A clamping opening is formed between the second clamping parts of the two second clamping claws. The first cover plate has a second linkage part that is linked and engaged with the second clamping claws. The second linkage part is opposite to the second mating part.

[0019] When the small sliding plate is placed on the flat surface and the first cover plate is pressed down, the first cover plate moves downward relative to the first base plate, and the second linkage part contacts the second mating part and pushes the second mating part to swing downward, causing the two second clamping parts to swing upward and clamp tightly.

[0020] When the first cover plate moves up and resets relative to the first base plate, the second linkage part moves up with the first cover plate, so that the two second clamping parts can swing downward and release under the action of gravity or the reset part connected to the second clamping claw.

[0021] A further preferred embodiment of this invention is as follows: the first clamping part is a row of first protruding teeth on the lower end of the first clamping claw, the first protruding teeth having raised first side teeth on both sides, the first clamping claw having a first hook head, the first hook head being on the same side of the first mating part as the first shaft, and a first tension spring being provided between the two opposing first clamping claws, the two ends of the first tension spring being respectively connected to the two first hook heads, the first tension spring being used to pull the two first clamping claws to swing back to the released state.

[0022] When clamped, the first protruding teeth on the two opposing first clamping claws are staggered.

[0023] When in the released state, the two opposing first clamping claws separate and tilt towards the middle of each other.

[0024] A further preferred embodiment of this invention is as follows: the second clamping part is a row of second protruding teeth on the lower end of the second clamping claw, and the two sides of the second protruding teeth are provided with raised second side teeth. The second clamping claw is provided with a second hook head, and the second hook head and the second mating part are located on the same side of the second shaft. A second tension spring is provided between the two opposing second clamping claws, and the two ends of the second tension spring are respectively connected to the two second hook heads. The second tension spring is used to pull the two second clamping claws to swing back to the released state.

[0025] When clamped, the second protruding teeth on the two opposing second clamping claws are staggered.

[0026] When in the released state, the two opposing second clamping claws separate and tilt towards the middle of each other.

[0027] Compared with the prior art, the advantages of this utility model are that the small mop can be connected to the cleaning object for cleaning when in use, or the small mop can be assembled with the large mop. After assembly, the cleaning object is connected to the large mop for cleaning. This realizes that one cleaning tool has two different sizes of mops for use to adapt to cleaning in different occasions. When placed, the small mop and the large mop can be combined into a cleaning tool, thereby avoiding the space occupied by a lot of cleaning tools and the placement will not look cluttered.

[0028] The first clamping mechanism on the large slide can clamp the wiping object by pressing the second cover plate down on the large slide. In the clamping state, the first cover plate and the first bottom plate are locked by the locking mechanism to prevent the second cover plate from moving away from the second bottom plate and keeping the first clamping mechanism in the clamping state. This clamping drive method is simple and easy to operate. Attached Figure Description

[0061] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0062] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0063] Figures 1-30As shown, the modular cleaning mop includes a mop handle 1, a small mop plate 3, and a large mop plate 2. The mop handle 1 is connected to the small mop plate 3. The small mop plate 3 can be connected to a cleaning object for cleaning, or the small mop plate 3 can be assembled with the large mop plate 2 for cleaning. When the small mop plate 3 is connected to a cleaning object, it is combined with the mop handle 1 to form a cleaning tool. When cleaning with the large mop plate 2 is required, the large mop plate 2 is assembled with the small mop plate 3. The mop handle 1, the small mop plate 3, and the large mop plate 2 are combined to form a cleaning tool, and the cleaning object is connected to the large mop plate 2 for cleaning. This allows a cleaning tool to have two different sizes of mop plates for different cleaning occasions. When placed, the small mop plate 3 and the large mop plate 2 can be combined into a single cleaning tool, thus avoiding the space occupied by multiple cleaning tools and preventing the placement from appearing cluttered.

[0064] Figures 19-29 As shown, the small tray 3 includes a first base plate 15 and a first cover plate 13 that can move vertically relative to the first base plate 15. The first cover plate 13 can move downward to close with the first base plate 15, or the first cover plate 13 can move upward to separate from the first base plate 15. A locking mechanism is provided between the first base plate 15 and the first cover plate 13. A second clamping mechanism 14 for clamping the wiping material is provided on the first base plate 15. When the first cover plate 13 is subjected to force to move downward or upward relative to the first base plate 15, the second clamping mechanism 14 can clamp or release. When the first cover plate 13 moves downward relative to the first base plate 15 to the closed state and the second clamping mechanism 14 is clamped, the locking mechanism can lock the first cover plate 13 and the first base plate 15 to move apart relative to each other, so that the second clamping mechanism 14 remains in the clamped state. This clamping drive method is simple and easy to operate. The mop handle 1 is connected to the first cover plate 13.

[0065] Figures 23-26 As shown, the second clamping mechanism 14 includes two second clamping claws 65, which are arranged opposite to each other. The second clamping claws 65 are rotatably connected to the bottom of the first base plate 15 via a second shaft 71. The second clamping claws 65 are provided with a second clamping part and a second mating part. The second clamping part and the second mating part are located on both sides of the second shaft 71, and a clamping opening is formed between the two second clamping parts. The first cover plate 13 is provided with a second linkage part that is linked and cooperates with the second clamping claws 65. The second linkage part is opposite to the second mating part.

[0066] When the small slide plate 3 is placed on the flat surface and the first cover plate 13 is pressed down, the first cover plate 13 moves down relative to the first bottom plate 15, and the second linkage part contacts the second mating part and pushes the second mating part to swing downward, so that the two opposing second clamping parts swing upward and clamp; when the first cover plate 13 moves upward and separates relative to the first bottom plate 15, the second linkage part moves upward with the first cover plate 13, so that the upper part of the second mating part is unrestricted, and the two second clamping parts can swing downward and loosen under their own weight or the action of the reset member connected to the second clamping claw 65.

[0067] The second clamping part is a row of second protruding teeth 61 provided on the lower end of the second clamping claw 65. The second protruding teeth 61 have raised second side teeth 70 on both sides. The second clamping claw 65 is provided with a second hook head 69. The second hook head 69 and the second mating part are located on the same side of the second shaft 71. A reset member is provided between the two opposing second clamping claws 65. The reset member is a second tension spring 66. The two ends of the second tension spring 66 are respectively connected to the two second hook heads 69. The second tension spring 66 has a force to pull the upper ends of the two second clamping claws 65 together, so that the two second clamping claws 65 swing back to the loosened state and open the clamping jaws.

[0068] When clamped, the second protruding teeth 61 on the two opposing second clamping claws 65 are staggered, so that the two second clamping claws 65 can clamp the wiping object more tightly and prevent the wiping object from coming off between the two second clamping claws 65. Second side teeth 70 are provided on both sides of the second protruding teeth 61. The second side teeth 70 are similar to the barbs on the second protruding teeth 61, so that the clamped wiping object is not easy to be pulled off in the lateral direction.

[0069] When released, the two opposing second clamping claws 65 separate and are tilted toward the middle. The tilted arrangement of the second clamping claws 65 causes the second clamping part at the lower end of the second clamping claw 65 to swing when pressed down, causing the second clamping part to swing upward toward the middle. When the second linkage part moves down and contacts the second mating part, the tilted second clamping claw 65 can also be more easily pushed by the second linkage part to swing, so that the second clamping claw 65 can swing to the clamping state better.

[0070] The second mating part is a second protrusion 64 located on the upper end of the second clamping claw 65. A second guide part 63 is provided on the outer end of the second protrusion 64. The second guide part 63 protrudes from the second protrusion 64, and a space for accommodating the second linkage part is formed between the protruding part and the second protrusion 64 for clamping the second linkage part in the clamping state. A second guide slope is provided on the side of the second guide part 63 away from the space. The second linkage part is a second rib 60 extending downward from the bottom of the first cover plate 13. When the first cover plate 13 is subjected to force and moves downward and the second rib 60 initially contacts the second mating part, the second clamping claw 65 is still in a state with a large tilt angle. The second guide slope is used to contact the second rib 60 to facilitate the second rib 60 pushing the second mating part downward along the second guide slope, making the action of the second rib 60 contacting and pushing the second clamping claw 65 to swing and clamp more smoothly. A slope is provided on one side of the lower end of the second rib 60 to facilitate the second rib 60 pushing the second clamping claw 65 to swing more smoothly.

[0071] The bottom of the first base plate 15 is provided with a first groove 57 corresponding to the second clamping mechanism 14. Two opposing second clamping claws 65 are rotatably disposed in the first groove 57. The top of the first base plate 15 is provided with a first through-hole 62 opposite to the second protruding rib 60, and the first through-hole 62 communicates with the first groove 57. When the two second clamping claws 65 are in the loose state, the second protruding teeth 61 are exposed outside the first groove 57, the second mating part rotates into the first through-hole 62 and abuts against one side of the first through-hole 62, and one side of the first through-hole 62 restricts the second clamping claws 65 from continuing to rotate and open; when the two second clamping claws 65 are in the clamping state, the second protruding teeth 61 of the two second clamping claws 65 rotate into the first groove 57 and interlock with each other, the second mating part rotates out from the first through-hole 62 and the second protruding rib 60 passes downward through the first through-hole 62 and abuts against the second mating part, the second protruding rib 60 can restrict the second mating part from swinging upward so that the two second clamping claws 65 are kept in the clamping state.

[0072] Preferably, the bottom of the first base plate 15 is provided with two sets of second clamping mechanisms 14 arranged from left to right, and the bottom of the first base plate 15 is provided with the same number of first grooves 57 as the second clamping mechanisms 14.

[0073] The first cover plate 13 is provided with a first guide post 58, and the first base plate 15 is provided with a first guide hole 59. The first guide post 58 can be slidably inserted into the first guide hole 59, limiting the first cover plate 13 and the first base plate 15 to move relative to each other in the vertical direction. A second spring 19 is supported between the first cover plate 13 and the first base plate 15. The second spring 19 has an elastic force that pushes the first cover plate 13 to move upward relative to the first base plate 15. When the locking mechanism is released, the second spring 19 can push the first cover plate 13 to move upward relative to the first base plate 15 and to move relative to the first guide hole 59. The base plate 15 is separated, and the small slide 3 is reset from the closed state to the open state. The first base plate 15 is provided with a first limiting buckle 67, and the first cover plate 13 is provided with a first locking part 68 that cooperates with the first limiting buckle 67. When the first cover plate 13 moves upward relative to the first base plate 15 and the small slide 3 is in the open state, the first limiting buckle 67 and the first locking part 68 cooperate to restrict the first cover plate 13 from continuing to move upward relative to the first base plate 15, so as to prevent the first base plate 15 and the first cover plate 13 from separating and to ensure the integrity of the small slide 3.

[0074] Figures 19-22As shown, the locking mechanism includes a locking member 5 and a third spring 16 disposed on the first cover plate 13. The locking member 5 is movable relative to the first cover plate 13. The locking member 5 is provided with a first latching part 17, and the first base plate 15 is provided with a second latching part 18. When the first cover plate 13 moves down relative to the first base plate 15 and closes, the first latching part 17 and the second latching part 18 form a latching connection to lock the first cover plate 13 and the first base plate 15, thereby restricting the relative movement and separation of the first cover plate 13 and the first base plate 15. The third spring 16 has a spring force that pushes the locking member 5 to move in the latching direction, so that the first latching part 17 and the second latching part 18 remain in the latching state. Moving the locking member 5 can disengage the first latching part 17 and the second latching part 18 from the latching connection.

[0075] Preferably, the top of the first cover plate 13 is provided with two hinge seats 4. The lower end of the mop handle 1 is hinged between the two hinge seats 4 through a hinge structure. The hinge seat 4 is provided with an inner cavity 40, which is connected to the bottom of the first cover plate 13. The side of the hinge seat 4 is provided with an opening. The lock 5 is movably disposed in the inner cavity 40. A part of the lock 5 is exposed to the outside from the opening on the side of the hinge seat 4 for pressing to unlock. The inner end of the lock 5 is provided with a receiving groove 44. A first through hole 43 is provided between the receiving groove 44 and the bottom of the lock 5. The upper edge of one side of the opening of the first through hole 43 serves as a first latching part 17. The second latching part 18 includes an upwardly extending and elastic first vertical rod 42. The top of the first vertical rod 42 is provided with a first latch head 41. The top of the first latch head 41 and one side of the first through hole 43 are both provided with guide slopes. When the first cover plate 13 moves down relative to the first base plate 15 and closes with the first base plate 15, the guide slope on the first through hole 43 contacts and presses against the guide slope on the first latch 41, causing the locking piece 5 to move into the inner cavity 40 along the guide slope until the first latch 41 passes through the first through hole 43 and enters the receiving groove 44. The third spring 16 pushes the locking piece 5 out of the inner cavity 40, so that the first latch 41 is stuck on the upper edge of one side of the first through hole 43. When unlocking is required, the locking piece 5 is pressed inward, so that the upper edge of one side of the first through hole 43 moves out from under the first latch 41. At this time, the first latch 41 is facing the first through hole 43 below. The second spring 19 opens the first base plate 15 and the first cover plate 13, so that the first latch 41 can move downward from the first through hole 43, thus unlocking.

[0076] Figure 30 As shown, the lock 5 is provided with second limiting buckles 73 on both sides, and the inner cavity 40 is provided with first limiting grooves 48 on both sides for the buckles of the second limiting buckles 73 to slide inside. When the third spring 16 pushes the lock 5 to move out of the inner cavity 40, the buckles of the second limiting buckles 73 can be stuck on one end of the first limiting groove 48 to restrict the lock 5 from leaving the inner cavity 40.

[0077] The inner cavity 40 is provided with a guide rod 46, and the top of the receiving groove 44 is provided with a guide groove 45. The guide rod 46 is inserted into the guide groove 45 to guide the movement of the locking member 5. The guide rod 46 contacts the top of the guide groove 45 to support the inner end of the locking member 5. During the lateral movement of the locking member 5, at least part of it is outside the inner cavity 40 and supported on the top surface of the first cover plate 13.

[0078] In the initial state, the two opposing second clamping claws 65 are separated and tilted towards the middle. The first cover plate 13 and the first bottom plate 15 are separated by the second spring 19, and there is a gap between the second rib 60 and the second mating part. When connecting the wiping material via the small sliding plate 3, the wiping material can be a wiping cloth. Place the wiping cloth to be connected on a flat surface, such as the ground, and then place the small sliding plate 3 on the wiping cloth. Press down the first cover plate 13 with the mop handle 1, causing the first cover plate 13 to move down relative to the first base plate 15 and close. During the pressing process, the two opposing second clamping claws 65 are squeezed and rotated by the ground, causing the lower ends of the second clamping claws 65 to swing upward and push the wiping cloth towards the middle, causing the wiping cloth to wrinkle and enter the clamping opening. After the first cover plate 13 moves down a certain distance, the second protruding rib 60 contacts the second mating part of the second clamping claw 65. During the downward movement, the second protruding rib 60 pushes the second mating part to swing downward, causing the second clamping part to swing upward until it reaches the clamping state. At this time, the first cover plate 13 and the first base plate 15 are in the closed state, and the first cover plate 13 moves down to close with the first base plate 15. When the first latching part 17 and the second latching part 18 are engaged, the first cover plate 13 and the second cover plate 9 are separated vertically. In this state, the second protruding rib 60 supports above the second mating part to prevent the second clamping part of the second cloth clamping claw 65 from loosening, thus locking the second clamping mechanism 14 in a clamped state. When it is necessary to remove the wiping cloth, the first latching part 17 and the second latching part 18 are disengaged by pressing the locking piece 5. At this time, the second spring 19 pushes the first cover plate 13 to move upward and separate it from the first base plate 15 from the closed state. The second protruding rib 60 moves upward with the first cover plate 13. During the upward movement of the second protruding rib 60, the second tension spring 66 pulls the two opposing second cloth clamping claws 65 with the second mating part to swing upward as the second protruding rib 65 moves upward, causing the lower part of the second clamping part of the second cloth clamping claw 65 to loosen the clamped wiping cloth, and the wiping cloth can be removed from the small slide plate 3.

[0079] Figures 12-17 As shown, the large sliding plate 2 includes a second base plate 10 and a second cover plate 9 that can move vertically relative to the second base plate 10. The second cover plate 9 can move down to close with the second base plate 10, or the second cover plate 9 can move up to separate from the second base plate 10. The second base plate 10 is provided with a first clamping mechanism for clamping the wiping object. When the second cover plate 9 is subjected to force and moves down or up relative to the second base plate 10, the first clamping mechanism can clamp or loosen.

[0080] Figures 1-11As shown, when the large sliding plate 2 is assembled onto the small sliding plate 3 for cleaning, the first cover plate 13 and the second cover plate 9 are detachably and fixedly connected, and the first bottom plate 15 and the second bottom plate 10 are detachably and fixedly connected. When the first cover plate 13 and the second cover plate 9 are subjected to downward pressure and move down relative to the first bottom plate 15 and the second bottom plate 10 to a closed state, and the first clamping mechanism clamps them, the locking mechanism can lock the first cover plate 13 and the first bottom plate 15 to restrict the relative movement and separation of the first cover plate 13 and the first bottom plate 15, so that the second cover plate 9 cannot move up relative to the second bottom plate 10 to separate, thereby keeping the first clamping mechanism in a clamped state. The large sliding plate 2 controls the clamping and releasing of the first clamping mechanism by lifting and pressing up and down, which is simple and convenient to operate. The clamping and locking of the small sliding plate 3 and the large sliding plate 2 are achieved by the same locking mechanism.

[0081] When the first cover plate 13 and the second cover plate 9 move up and down relative to the first base plate 15 and the second base plate 10 to control the clamping and releasing of the first clamping mechanism, since the first base plate 15 abuts against the second base plate 10 and their relative positions remain unchanged, the second cloth clamping claw 65 is always retracted into the first groove 57 by the restriction of the lower second base plate 10 and is in a horizontal position, and is not affected by the second protruding rib 60 on the first cover plate 13.

[0082] The first clamping mechanism includes two first clamping claws 11, which are arranged opposite to each other. The first clamping claws 11 are rotatably connected to the bottom of the second base plate 10 via a first shaft 54. The upper and lower ends of the first clamping claws 11 are respectively provided with a first mating part and a first clamping part. The first clamping part and the first mating part are located on both sides of the first shaft 54. A clamping opening is formed between the first clamping parts of the two first clamping claws 11. The second cover plate 9 is provided with a first linkage part that is linked and engaged with the first clamping claws 11. The first linkage part is opposite to the first mating part.

[0083] When the large sliding plate 2 is placed on the flat surface and the second cover plate 9 is pressed down, the second cover plate 9 moves down relative to the second bottom plate 10 and closes, and the first linkage part contacts the first mating part and pushes the first mating part to swing downward, so that the two first clamping parts swing upward and clamp; when the second cover plate 9 moves upward relative to the second bottom plate 10, the first linkage part moves upward with the second cover plate 9, so that the two first clamping parts can swing downward and loosen under their own weight or the action of the reset part connected to the first clamping claw 11.

[0084] The first clamping part is a row of first protruding teeth 37 provided on the lower end of the first cloth clamping claw 11. The first protruding teeth 37 have protruding first side teeth 55 on both sides. The first cloth clamping claw 11 is provided with a first hook head 53. The first hook head 53 and the second mating part are located on the same side of the first shaft 54. A reset member is provided between the two opposing first cloth clamping claws 11. The reset member is a first tension spring. The two ends of the first tension spring are respectively connected to the two first hook heads 53. The first tension spring has the force to pull the upper ends of the two first cloth clamping claws 11 together, so that the two first cloth clamping claws 11 swing back to the loosened state and open the clamping mouth.

[0085] When clamped, the first protruding teeth 37 on the two opposing first clamping claws 11 are staggered, so that the two first clamping claws 11 can clamp the wiping object more tightly and prevent the wiping object from coming off between the two first clamping claws 11. First side teeth 55 are provided on both sides of the first protruding teeth 37. The first side teeth 55 are similar to the barbs on the first protruding teeth 37, so that the clamped wiping object is not easy to be pulled off in the lateral direction.

[0086] In the released state, the two opposing first clamping claws 11 separate and are tilted towards the middle. The tilted arrangement of the first clamping claws 11 causes the first clamping part at the lower end of the first clamping claw 11 to swing when pressed down, causing the first clamping part to swing upward towards the middle. When the first linkage part moves down and contacts the first mating part, the tilted first clamping claw 11 can also be more easily pushed by the first linkage part to swing, so that the first clamping claw 11 can swing to the clamping state better.

[0087] The first mating part is a first protrusion 38 located on the upper end of the first clamping claw 11. A first guide part 39 is provided on the outer end of the first protrusion 38. The first guide part 39 protrudes from the first protrusion 38, and a space for accommodating the first linkage part is formed between the protruding part and the first protrusion 38 for clamping in the clamping state. A first guide slope is provided on the side of the first guide part 39 away from the space. The first linkage part is a first rib 34 extending downward from the bottom of the second cover plate 9. When the second cover plate 9 is subjected to force and moves downward and the first rib 34 initially contacts the first mating part, the first clamping claw 11 is still in a state with a large tilt angle. The first guide slope is used to contact the first rib 34 to facilitate the first rib 34 to push the first mating part downward along the first guide slope, making the action of the first rib 34 contacting and pushing the first clamping claw 11 to swing and clamp more smoothly. A slope is provided on one side of the lower end of the first rib 34 to facilitate the first rib 34 to push the first clamping claw 11 to swing more smoothly.

[0088] The bottom of the second base plate 10 is provided with a second groove 28 corresponding to the first clamping mechanism. Two opposing first clamping claws 11 are rotatably disposed in the second groove 28. The top of the second base plate 10 is provided with a second through-hole 36 opposite to the first protruding rib 34. The second through-hole 36 communicates with the second groove 28. When the two first clamping claws 11 are in the loose state, the first protruding tooth 37 is exposed outside the second groove 28. The first mating part rotates into the second through-hole 36 and abuts against the downward extending side guard 35 on one side of the second through-hole 36. The side guard 35 restricts the first clamping claws 11 from continuing to rotate and open. When the two first clamping claws 11 are in the clamping state, the first protruding tooth 37 of the two first clamping claws 11 rotates into the second groove 28 and intersects with each other. The first mating part rotates out from the second through-hole 36 and the first protruding rib 34 passes downward through the second through-hole 36 and abuts against the first mating part. The first protruding rib 34 can restrict the first mating part from swinging upward so that the two first clamping claws 11 are kept in the clamping state.

[0089] Preferably, the bottom of the second base plate 10 is provided with two sets of first clamping mechanisms arranged left and right, and the bottom of the second base plate 10 is provided with the same number of second grooves 28 as the first clamping mechanisms.

[0090] The second cover plate 9 is provided with a second guide post 23, and the second base plate 10 is provided with a second guide hole 24. The second guide post 23 can be slidably inserted into the second guide hole 24, limiting the second cover plate 9 and the second base plate 10 to move relative to each other in the vertical direction. A fourth spring 27 is supported between the second cover plate 9 and the second base plate 10. The fourth spring 27 has an elastic force to push the second cover plate 9 to move upward relative to the second base plate 10 and reset. When the locking mechanism is released, the fourth spring 27 can push the second cover plate 9 to move upward relative to the second base plate 10, resetting the large slide plate 2 from the closed state to the open state. At least one of the second guide posts 23 is connected to a screw 26. The head of the screw 26 is accommodated in the second guide hole 24. The second guide hole 24 is provided with a step 25. The step 25 cooperates with the head of the screw 26 to restrict the second base plate 10 from moving away from the second cover plate 9, ensuring the integrity of the large slide plate 2.

[0091] Alternatively, screw 26 and fourth spring 27 can be omitted. The upward movement of the second cover plate 9 can be driven by the second spring 19 pushing the first cover plate 13 to move upward relative to the first base plate 15. During assembly and use, the second cover plate 9 and the second base plate 10 are connected to the first cover plate 13 and the first base plate 15 respectively. Even without screw 26, the second base plate 10 will not detach from the second cover plate 9 during use.

[0092] When the large slide 2 and the small slide 3 are assembled and used, in the initial state, the first cover plate 13 and the first bottom plate 15 of the small slide 3, as well as the second cover plate 9 and the second bottom plate 10 of the large slide 2, are all in a state of being spread apart with a gap. The two first cloth clamping claws 11 at the bottom of the second bottom plate 10 are open and tilted towards the middle. There is a gap between the first protruding rib 34 and the first mating part. When connecting the wiping material via the large mop 2, the wiping material can be a wiping cloth. Place the wiping cloth to be connected on a flat surface, such as the ground, and then place the large mop 2 on the wiping cloth. Press down the first cover plate 13 with the mop handle 1, causing the first cover plate 13 and the second cover plate 9 to move down relative to the first base plate 15 and the second base plate 10 and close together. During the pressing process, the two opposing first clamping claws 11 are squeezed and rotated by the ground, causing the lower ends of the first clamping claws 11 to swing upward and push the wiping cloth towards the middle, causing the wiping cloth to wrinkle and enter the clamping opening. After the second cover plate 9 moves down a certain distance, the first protruding rib 34 contacts the first mating part of the first clamping claw 11. During the downward movement, the first protruding rib 34 pushes the first mating part to swing downward, causing the first clamping part to swing upward until it reaches the clamping state. At this time, the first cover plate 13 and the first base plate 15, as well as the second cover plate 9 and the second base plate 10, are all in the closed state, and the first cover plate 13 moves down to the first base plate 15 and the second base plate 10. When the base plate 15 is closed, the first latching part 17 and the second latching part 18 are engaged to restrict the separation of the first cover plate 13 and the second cover plate 9. In this state, the first protruding rib 34 supports the first mating part to restrict the lower swing of the first clamping part of the first cloth clamping claw 11 from loosening, locking the first clamping mechanism in a clamped state. When it is necessary to remove the wiping cloth, the first latching part 17 and the second latching part 18 are disengaged by pressing the locking piece 5. At this time, the second spring 19 and the fourth spring 27 respectively push the first cover plate 13 and the first base plate 15, as well as the second cover plate 9 and the second base plate 10, to separate from the closed state. The first protruding rib 34 moves upward with the second cover plate 9. During the upward movement of the first protruding rib 34, the first tension spring pulls the two opposite first cloth clamping claws 11 with the first mating part to swing upward with the first protruding rib 34, so that the lower swing of the first clamping part of the first cloth clamping claw 11 loosens the clamped wiping cloth, and the wiping cloth can be removed from the large slip plate 2.

[0093] The top of the second cover plate 9 is provided with an assembly groove 8 for accommodating the small mop 3. The bottom of the assembly groove 8 is provided with a first opening 47. When the large mop 2 and the small mop 3 are assembled, the small mop 3 is placed in the assembly groove 8. The second cover plate 9 is provided with a first connector 6 for connecting the first cover plate 13 and the second cover plate 9 together. The second base plate 10 is provided with a second connector 12 for connecting the first base plate 15 and the second base plate 10 together. The first cover plate 13 and the second cover plate 9 are integrated, and the first base plate 15 and the second base plate 10 are integrated to form a cleaning tool with the large mop 2 as the mop head. The small mop 3 is placed in the assembly groove 8 and just fills the assembly groove 8.

[0094] The first connector 6 is movably mounted on the second cover plate 9. The first connector 6 has a control part 20 extending from the top of the second cover plate 9 and an insert 49 extending into the assembly groove 8 from the inner side wall of the assembly groove 8. The first cover plate 13 has an insertion port 56 that mates with the insert 49. The insert 49 is inserted into the insertion port 56 to connect the first cover plate 13 and the second cover plate 9 together. A first spring 22 is provided between the first connector 6 and the second cover plate 9. The first spring 22 acts on the first connector 6 to keep the insert 49 in the insertion port 56. Moving the first connector 6 can cause the insert 49 to exit the insertion port 56, thereby disconnecting the connection between the first cover plate 13 and the second cover plate 9. The first cover plate 13 and the second cover plate 9 can be separated.

[0095] Preferably, there are two first connectors 6, and movable grooves 21 are provided on the inner walls on both sides of the assembly groove 8. The first connectors 6 are placed in the movable grooves 21 and move. The top of the second cover plate 9 is provided with a second opening 7 that communicates with the movable grooves 21, and the control part 20 extends out from the second opening 7.

[0096] Regarding the connection method of the first connector 6, the first connector 6 can also be rotated to allow the insert 49 to be inserted into or removed from the socket 56.

[0097] The second connector 12 is rotatably mounted on the second base plate 10. One of the second connector 12 and the second base plate 10 is provided with a locking block 52, and the other is provided with a locking groove 74 that cooperates with the locking block 52. The second connector 12 includes a rotary dial 29 and a connecting post 33 fixed on the rotary dial 29. The rotary dial 29 is located at the bottom of the second base plate 10. The connecting post 33 passes through the second base plate 10 and extends into the assembly groove 8. The side of the connecting post 33 is provided with a protruding locking block 50. The first base plate 15 is provided with a first through hole 72 for the connecting post 33 to pass through. The connecting post 33 passes through the first through hole 72. The second connector 12 can rotate and switch between a locking position and a releasing position. When the second connector 12 is rotated to the engaging position, the locking block 50 is engaged on the upper edge of the first through hole 72 to prevent the connecting post 33 from disengaging downward from the first through hole 72. At this time, the locking block 52 falls into the locking groove 74 to lock the second connector 12 to rotate relative to the second base plate 10. When the second connector 12 is rotated to the releasing position, the connecting post 33 can move downward relative to the first base plate 15 to disengage from the first through hole 72.

[0098] The rotary dial 29 has vertically extending edges 30 on both sides of the connecting post 33, each extending upwards. Each vertically extending edge 30 has a limiting protrusion 32. The second base plate 10 has an arc-shaped track hole 31 through which the vertically extending edge 30 passes and moves. One end of the arc-shaped track hole 31 has a third opening 51 through which the vertically extending edge 30 and the limiting protrusion 32 pass or move out. The limiting protrusion 32 is positioned above one side of the arc-shaped track hole 31 to restrict the second connection. Part 12 detaches downward from the second base plate 10. Locking block 52 is located on one side of the arc-shaped track hole 31, and locking groove 74 is located at the bottom of limiting protrusion 32. When the second connecting member 12 rotates, the limiting protrusion 32 contacts and presses against the locking block 52, causing elastic deformation. This allows the limiting protrusion 32 to rotate until the locking block 52 falls into the locking groove 74. Similarly, when the second connecting member 12 rotates, the locking block 52 is pressed against the inner wall of the locking groove 74, causing elastic deformation. This allows the locking block 52 to detach from the locking groove 74. Guide slopes for guidance can be provided on the locking block 52, locking groove 74, and limiting protrusion 32.
