Description

[Technical Field]

[0001] The present invention relates to the technical field of cleaning tools, and more particularly to a clip-on mop that allows for easy replacement of the cleaning cloth. [Background technology]

[0002] Mops are commonly used to clean floors; a rag is attached to the mop holder, and the floor is cleaned by holding the mop handle. Commercially available mops often use fixed mops, which make it inconvenient to replace the rag and become dirty after long use. However, disposing of them directly leads to a waste of resources.

[0003] In the prior art, such as CN205729270U, ​​a new dust cloth gripping structure and mop are disclosed, which include a plate and a dust cloth, the plate including an aluminum support plate, a base plate engaged with the underside of the aluminum support plate, two dust cloth gripping plates rotatably connected to both sides of the aluminum support plate, and two stoppers provided at both ends of the aluminum support plate, and a chute and a protrusion are provided on each side of the aluminum support plate, and the dust cloth gripping plate is provided with at least two rotating shaft-shaped engaging members engaged with the chute and at least two engaging teeth corresponding to the protrusions to grip and fix the dust cloth. While this structure achieves the purpose of changing the dust cloth, it requires the user to manually rotate the dust cloth gripping plate, making it inconvenient to change the dust cloth. Summary of the Invention

[0004] (1) The technical problem to be solved The technical problem that the present invention aims to solve is to provide a dust cloth gripping mop that allows for easy dust cloth replacement, which includes a drive assembly that connects the second gripping member and the handle, and by lifting or pushing down the handle, the second gripping member can be controlled to move closer to or farther away from the first gripping member, thereby achieving the gripping of the dust cloth when moving closer and the release of the dust cloth when moving away, and has a simple structure and makes it easier to replace the dust cloth.

[0005] (2) Technical solutions The solution adopted by the present invention to solve the above technical problems is to provide a dust cloth gripping mop that allows easy dust cloth replacement, the dust cloth gripping mop comprising a handle and a mop base plate connected to one end of the handle, the mop base plate having a gripping assembly for gripping a dust cloth, the gripping assembly including a first gripping member fixed to an end of the mop base plate remote from the handle and a second gripping member movably connected to the mop base plate and movable toward or away from the first gripping member, the mop base plate having a drive assembly for driving the second gripping member toward or away from the first gripping member, the handle connected to the drive assembly, and the drive assembly is controlled by lifting or depressing the handle to drive the second gripping member toward or away from the first gripping member.

[0006] Specifically, the dust cloth is a thin nonwoven fabric.

[0007] Optionally, the mop base can be placed on a wipe by lifting the handle and moving the second gripping member away from the first gripping member, and the wipe can be gripped between the first and second gripping members by pushing down the handle and moving the second gripping member closer to the first gripping member. When releasing, the second gripping member is lifted and moves away from the first gripping member, allowing the wipe to fall, and when gripping, a portion of the wipe is sandwiched between the first and second gripping members, achieving the purpose of gripping the wipe.

[0008] Optionally, the handle is depressed to control the second gripping member away from the first gripping member, and the handle is lifted to control the second gripping member toward the first gripping member.

[0009] The above solution provides a drive assembly for connecting the second gripping member and the handle, and by lifting or depressing the handle, the second gripping member can be controlled to move closer to or away from the first gripping member, thereby gripping the wipe when moved closer and releasing the wipe when moved away, which has a simple structure and makes it easier to replace the wipe.

[0010] Additionally, the drive assembly includes a drive gear, and the second gripping member includes a rack portion that meshes with the drive gear.

[0011] Furthermore, the second gripping members are provided at opposite ends of the first gripping member, which are arranged on the same plane.

[0012] The drive gear is mounted in the inner cavity of the mop base plate and rotates around the central axis of the handle.

[0013] The internal cavity of the mop base plate is provided with gripping drive members on both sides opposite the drive gear, and one end of the gripping drive member is provided with the rack portion, and the other end extends from the internal cavity of the mop base plate and is connected to the second gripping member.

[0014] Preferably, the second gripping member is connected below the gripping drive member by a snap connection.

[0015] Specifically, by arranging the two gripping drive members on opposite sides of the drive gear, the rotation of the drive gear can drive the two gripping drive members to move synchronously, thereby driving the two second gripping members to move closer to or away from the first gripping member synchronously, making it easier to replace the wipes.

[0016] Furthermore, the rack portion has first and second limiting portions at both ends of its tooth portion for limiting the drive gear, and when the drive gear rotates to a position where it abuts against the first limiting portion, the second gripping member moves as far away from the first gripping member as possible, and the first and second gripping members are in a maximum open state, making it easier for the dust cloth to fall.When the drive gear rotates to a position where it abuts against the second limiting portion, the second gripping member moves as close as possible to the first gripping member, and the first and second gripping members are in a locked state, resulting in a more reliable dust cloth gripping function.

[0017] Preferably, the rack portion is provided above the gripping drive member, and the rack portion of any of the gripping drive members is partially positioned above the other gripping drive members, and the extension direction of the tooth portion of the rack portion is parallel to the movement direction of the gripping drive member and the second gripping member, and at the same time, when the drive gear rotates to a position where it abuts against the second limiting portion, the adjacent end surfaces of the two gripping drive members abut against each other, further restricting their relative movement, resulting in a more reliable wipe gripping function.

[0018] According to the above-described solution, by providing the first limiting portion and the second limiting portion, it is possible to prevent the first gripping member from coming off the mop bottom plate, thereby improving reliability during use.

[0019] Furthermore, the mop base plate includes a cover connected to the handle and the first gripping member detachably connected to the side of the mop base plate away from the handle, and a protrusion opening is provided on the side of the cover for the gripping drive member to protrude, and an opening is provided on the end of the cover away from the first gripping member for the drive gear to partially protrude and connect to the handle.

[0020] Preferably, the bottom of the cover is provided with a plurality of buckle members extending downward, and the first gripping member is provided with buckle holes that engage with the buckle members, thereby realizing a detachable connection between the two and facilitating subsequent maintenance.

[0021] Optionally, in another solution, the drive assembly comprises a cam that rotates around the central axis of the handle and a reset member for resetting the second gripping member, and in this structure, when the most protruding part of the cam abuts against the second gripping member, the second gripping member and the first gripping member are in an open state, and when the cam rotates and its most protruding part slowly disengages from the second gripping member, the second gripping member is driven by the reset member to approach the first gripping member until the first gripping member and the second gripping member are locked.

[0022] Furthermore, a first toothed zone is provided at the end of the first gripping member facing the second gripping member, and a second toothed zone is provided at the end of the second gripping member facing the first gripping member, and the first toothed zone and the second toothed zone are positioned offset from each other to improve the robustness of the wipe grip.

[0023] The handle further comprises an outer rod connected to the mop base plate and an inner rod slidably fitted within the outer rod, the inner rod having a screw, and at least a portion of the inner wall of the inner rod engaging with the screw, wherein the screw is connected to the drive assembly by a connector.

[0024] Specifically, the screw is rotatably connected to a part of the drive gear extending from the mop base plate by a connector, and an outer connector is connected to the bottom of the outer rod, and the outer connector is externally fitted to the outside of the connector, and the outer connector is rotatably connected to the mop base plate, and the upper end of the mop base plate is provided with a joint rotatably connected to the outer connector, and since the rotation direction of the connector and the drive gear is the same as the rotation direction of the outer connector and the mop base plate, the angle between the two can be adjusted by rotating the entire handle relative to the mop base plate.

[0025] Furthermore, the lower end of the inner rod is formed with a plurality of circular, equally spaced elastic buckles extending downward, and the outer wall of the screw is formed with protrusions that engage with the elastic buckles.

[0026] During use, the inner rod is lifted, disengaging the screw's protrusion from the elastic buckle and engaging the inner wall of the inner rod with the screw, allowing the screw to rotate, which rotates the drive gear via the connector and drives the second gripping member away from the first gripping member, releasing them. When gripping, the inner rod is pushed down, engaging the inner wall of the inner rod with the screw, allowing the screw to rotate in the opposite direction relative to the first gripping member, which rotates the drive gear via the connector and drives the second gripping member toward the first gripping member, locking them together and gripping the wipe. At the same time, the screw's protrusion is locked into the elastic buckle, allowing the screw and inner rod to lock together, thereby increasing firmness during subsequent use.

[0027] Furthermore, an axially arranged guide slide is provided on at least a portion of the inner wall of the outer rod, and correspondingly, a guide chute adapted to the guide slide is provided on the inner rod to prevent offset between the inner rod and the outer rod.

[0028] Furthermore, the second gripping members are provided at opposite ends of the first gripping member, which are located in the same plane, and the drive assembly can move the two second gripping members closer to or farther away from each other along the planar direction of the first gripping member, making it easier to replace the wipes.

[0029] The drive assembly further includes a link mechanism connected between one end of the mop base plate adjacent to the handle and the second gripping member, a resilient member acting between the two second gripping members to give the two second gripping members a tendency to move in opposite directions to each other, and a pressing member connected to one end of the handle adjacent to the mop base plate and acting on the link mechanism to drive the two second gripping members in a direction toward each other.

[0030] Preferably, a first toothed zone is provided at the end of the first gripping member facing the second gripping member, and a second toothed zone is provided at the end of the second gripping member facing the first gripping member, and the first toothed zone and the second toothed zone are offset from each other to improve the firmness of the grip on the wipe.

[0031] Specifically, the handle includes an outer rod connected to the mop base plate and an inner rod slidably fitted within the outer rod, with the outer rod fixed to the mop base plate. The pressing member is connected to the lower end of the inner rod, and the pressing member can be moved up and down synchronously by lifting and pushing down the inner rod. After the inner rod is lifted to move the pressing member upward, the pressing member disengages from the link mechanism, whereby the repulsive force of the elastic member urges the two second gripping members away from each other, separating the second gripping members from the first gripping members, loosening the mop cloth and facilitating its replacement. After the inner rod is pushed down to move the pressing member downward, the pressing member applies force to the link mechanism, moving the two second gripping members toward each other, bringing the second gripping members toward the first gripping members and locking the first and second gripping members, improving the robustness of the mop cloth grip.

[0032] Furthermore, the link mechanism includes a first link hingedly connected to each of the two second gripping members, and two second links hingedly connected to the other ends of the two first links, the other ends of the two second links being hingedly connected to one end of the mop base plate adjacent to the handle. After the handle is lifted, the pressing member disengages from the link mechanism, and the two second gripping members move in directions away from each other due to the repulsive force of the elastic member. At the same time, the hinge connection portions between the first and second links are relatively expanded upward and outward until the first and second links are positioned on the same straight line, and at this time, the second gripping members are maximally separated from the first gripping members. After the handle is pressed down, the pressing member acts on the link mechanism to move the hinge connection between the first link and the second link relatively inward and downward, driving the two second gripping members to move in a direction toward each other, at which time the second gripping member comes as close as possible to the first gripping member, and at the same time, the first link and the second link become approximately vertical.

[0033] Preferably, there are two sets of link mechanisms, which are arranged symmetrically with respect to the handle. There are two sets of elastic members, which are arranged symmetrically with respect to the handle. Each second gripping member includes an elongated gripping rod provided with the second toothed zone and an extension rod extending from the gripping rod toward the other second gripping member. Each of the gripping rods located on both sides of the handle is provided with two extension rods, and a connection portion between the extension rod and the gripping rod is provided with an abutment portion for abutting the elastic member, and the extension rod further has an accommodating slot for accommodating the elastic member by connecting with the abutment portion, and the elastic member is disposed in the accommodating slot of the two extension rods, and both ends of the elastic member abut against the two abutment portions, respectively. When the first gripping member and the second gripping member are in a locked state, the elastic member is in a state of storing compression energy. Next, after the pressing member is released from the link mechanism, the repulsive force of the accumulated compression energy of the elastic member causes the two second gripping members to move away from each other, causing the second gripping members to move away from the first gripping members, loosening the wipe and making it easier to replace the wipe.

[0034] Furthermore, the mop base plate is provided with a movement groove for moving the pressing member along the movement direction of the handle, and the movement groove is provided with a first limiting portion and a second limiting portion at both ends in the movement direction of the handle. The first limiting portion is provided adjacent to the handle, and the second limiting portion is provided adjacent to the mop base plate. When the handle is lifted until the pressing member abuts the first limiting portion, the second gripping member moves in a direction away from the first gripping member to the maximum extent, and when the handle is moved downward until the pressing member abuts the second limiting portion, the second gripping member moves closest to the first gripping member to the maximum extent.

[0035] Preferably, a locking structure is further provided between the outer wall of the inner rod and the inner wall of the outer rod, and when the pressing member moves the inner rod downward until it abuts the second limiting portion, the locking structure locks the inner rod and the outer rod and restricts the sliding movement of the inner rod relative to the outer rod, and at this time, the second gripping member is maximally close to the first gripping member, i.e., the first gripping member and the second gripping member are in a locked state.

[0036] Specifically, the moving groove communicates with the internal cavity of the mop base plate, and the pressing member includes a pressing portion extending into the moving groove and pressing against the link mechanism. The pressing member further includes a sliding portion located directly below the inner rod, and the mop base plate is provided with a chute for the sliding portion to slide, and the sliding portion is always positioned on the chute to more stably move the pressing member. The sliding portions located at both ends of the inner rod are each provided with two pressing portions, each applying force to the link mechanism. At the same time, the pressing portions move along the outer wall of the second link when the link mechanism is extended or retracted.

[0037] (3) Beneficial Effects Compared with the prior art, the present invention designs a dust cloth gripping mop with easy dust cloth replacement, which includes a drive assembly connecting the second gripping member and the handle, and the second gripping member can be controlled to move closer to or farther away from the first gripping member by lifting or pushing down the handle, thereby achieving gripping the dust cloth when moving closer and releasing the dust cloth when moving away, which has a simple structure and makes dust cloth replacement easier.

DETAILED DESCRIPTION OF THE INVENTION

[0040] Hereinafter, specific embodiments of the present invention will be described in more detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0041] In the description of the present invention, unless expressly specified and limited, it should be noted that the terms "attached," "connected," and "coupled" are understood in a broad sense, and may refer to, for example, a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, or a connection between two elements. Those skilled in the art will be able to understand the specific meaning of the above terms in the present invention in specific cases.

[0042] Example 1 As shown in Figures 1 to 9, this embodiment is a rag-gripping mop that allows for easy rag replacement, and the rag-gripping mop comprises a handle 1 and a mop base plate 2 connected to one end of the handle 1. The mop base plate 2 is provided with a gripping assembly 21 that grips the rag, and the gripping assembly 21 comprises a first gripping member 211 fixed to an end of the mop base plate 2 away from the handle 1, and a second gripping member 212 that is movably connected to the mop base plate 2 and can be moved closer to or away from the first gripping member 211. Here, the mop base plate 2 is provided with a drive assembly 22 for driving the second gripping member 212 toward or away from the first gripping member 211, and the handle 1 is connected to the drive assembly 22. By lifting or pressing down the handle 1, the drive assembly 22 is controlled to drive the second gripping member 212 toward or away from the first gripping member 211. Specifically, the wipe is a thin nonwoven fabric. In this embodiment, by lifting the handle 1 and moving the second gripping member 212 away from the first gripping member 211, the mop base plate 2 is placed on the wipe, and by pressing down the handle 1 and moving the second gripping member 212 toward the first gripping member 211, the wipe is held between the first gripping member 211 and the second gripping member 212, thereby achieving the gripping function. When releasing, the handle 1 is lifted, and the second gripping member 212 separates from the first gripping member 211, allowing the wipe to fall; when gripping, part of the wipe is pinched between the first gripping member 211 and the second gripping member 212, achieving the purpose of gripping the wipe. According to the above solution, a drive assembly 22 is provided for connecting the second gripping member 212 and the handle 1, and by lifting or pushing down the handle 1, the second gripping member 212 can be controlled to move closer to or farther away from the first gripping member 211, thereby gripping the wipe when moved closer and releasing the wipe to release the wipe, resulting in a simple structure and easier wipe replacement.

[0043] As shown in FIGS. 4 to 9 , the drive assembly 22 further includes a drive gear 221, and the second gripping member 212 includes a rack portion 212-1 that meshes with the drive gear 221. The second gripping members 212 are provided at opposite ends of the first gripping member 211, which are arranged on the same plane. The drive gears 221 are provided in the internal cavity of the mop base plate 2 and rotate around the central axis of the handle 1. The internal cavity of the mop base plate 2 is provided with gripping drive members 213 on both sides opposite the drive gear 221, and the rack portion 212-1 is provided at one end of the gripping drive member 213, and the other end extends from the internal cavity of the mop base plate 2 and is connected to the second gripping member 212. Preferably, the second gripping member 212 is attached below the gripping drive member 213 by a snap connection. Specifically, by arranging the two gripping drive members 213 on opposite sides of the drive gear 221, the rotation of the drive gear 221 can drive the two gripping drive members 213 to move synchronously, thereby driving the two second gripping members 212 to move toward or away from the first gripping member 211 synchronously, making it easier to replace the dust cloth. Furthermore, the rack portion 212-1 is provided with a first limiting portion 212-1a and a second limiting portion 212-1b at both ends of its tooth portion for limiting the drive gear 221. When the drive gear 221 rotates to a position where it abuts against the first limiting portion 212-1a, the second gripping member 212 is separated from the first gripping member 211 to the maximum extent, and the first gripping member 211 and the second gripping member 212 are in a state of being fully opened, making it easier for the dust cloth to fall. When the drive gear 221 rotates to a position where it abuts against the second limiting portion 212-1b, the second gripping member 212 comes as close as possible to the first gripping member 211, and the first gripping member 211 and the second gripping member 212 are locked together, thereby providing a more reliable dust cloth gripping function.Preferably, the rack portion 212-1 is disposed above the gripping drive members 213, and the rack portion 212-1 of any one of the gripping drive members 213 is partially disposed above the other gripping drive members 213. The extending direction of the teeth of the rack portion 212-1 is parallel to the moving direction of the gripping drive members 213 and the second gripping member 212. At the same time, when the drive gear 221 rotates to a position where it abuts against the second limiting portion 212-1b, the adjacent end faces of the two gripping drive members 213 abut against each other, further restricting their relative movement, resulting in a more reliable dust cloth gripping function. According to the above solution, the provision of the first limiting portion 212-1a and the second limiting portion 212-1b prevents the first gripping member 211 from coming off the mop base plate 2, improving safety during use. Furthermore, the mop base plate 2 includes a cover 23 connected to the handle 1 and the first gripping member 211 detachably coupled to the side of the mop base plate 2 away from the handle 1, the side of the cover 23 is provided with a protrusion opening 231 through which the gripping drive member 213 protrudes, and the end of the cover 23 away from the first gripping member 211 is provided with an opening 232 through which the drive gear 221 partially protrudes and is coupled to the handle 1. Preferably, the bottom of the cover 23 is provided with a plurality of buckle members 233 extending downward, and the first gripping member 211 is provided with buckle holes 211-2 that engage with the buckle members 233, realizing a detachable connection between them and facilitating subsequent maintenance. Furthermore, a first toothed zone 211-1 is provided at the end of the first gripping member 211 facing the second gripping member 212, and a second toothed zone 212-2 is provided at the end of the second gripping member 212 facing the first gripping member 211, and the first toothed zone 211-1 and the second toothed zone 212-2 are positioned offset from each other to improve the robustness of the rag grip.

[0044] As shown in Figures 10 to 13, the handle 1 further includes an outer rod 11 connected to the mop base plate 2 and an inner rod 12 slidably fitted within the outer rod 11, the inner rod 12 is provided with a screw 13, and at least a portion of the inner wall of the inner rod 12 is engaged with the screw 13, where the screw 13 is connected to the drive assembly 22 by a connector 14. Specifically, the screw 13 is rotatably connected to a portion of the drive gear 221 extending from the mop base plate 2 by a connector 14, an outer connector 15 is connected to the bottom of the outer rod 11, the outer connector 15 is fitted onto the outside of the connector 14, and the outer connector 15 is rotatably connected to the mop base plate 2, and the upper end of the mop base plate 2 is provided with a joint 24 rotatably connected to the outer connector 15, and the rotation direction of the connector 14 and the drive gear 221 is the same as the rotation direction of the outer connector 15 and the mop base plate 2, so that the angle between them can be adjusted by rotating the entire handle 1 relative to the mop base plate 2. Furthermore, the lower end of the inner rod 12 is formed with a plurality of annular elastic buckles 121 extending downward and arranged at equal intervals, and the outer wall of the screw 13 is formed with protrusions 131 that engage with the elastic buckles 121. In use, the inner rod 12 is lifted, the protrusion 131 of the screw 13 disengages from the elastic buckle 121, and the inner wall of the inner rod 12 engages with the screw 13, allowing the screw 13 to rotate, which in turn rotates the drive gear 221 via the connector 14 and drives the second gripping member 212 away from the first gripping member 211, releasing them. When gripping, the inner rod 12 is pushed down, and the inner wall of the inner rod 12 engages with the screw 13, allowing the screw 13 to rotate in the opposite direction relative to the connector 14, which in turn rotates the drive gear 221 in the opposite direction relative to the connector 14 and drives the second gripping member 212 toward the first gripping member 211, gripping them together and gripping the wipe.At the same time, the protrusion 131 of the screw 13 is locked into the elastic buckle 121, enabling the lock between the screw 13 and the inner rod 12, thereby increasing the firmness during subsequent use. Furthermore, the inner wall of the outer rod 11 is provided with a plurality of guide slides 111 arranged axially and at equal intervals, and correspondingly, the inner rod 12 is provided with a guide chute 122 adapted to the guide slides 111, preventing offset between the inner rod 12 and the outer rod 11.

[0045] Example 2 As shown in Figures 14 to 25, this embodiment discloses a rag-gripping mop that allows for easy rag replacement, and the rag-gripping mop comprises a handle 1 and a mop base plate 2 connected to one end of the handle 1. The mop base plate 2 is provided with a gripping assembly 21 that grips the rag. The gripping assembly 21 comprises a first gripping member 211 fixed to an end of the mop base plate 2 away from the handle 1, and a second gripping member 212 that is movably connected to the mop base plate 2 and can be moved closer to or away from the first gripping member 211. Here, the mop base plate 2 is provided with a drive assembly 22 for driving the second gripping member 212 toward or away from the first gripping member 211, and the handle 1 is connected to the drive assembly 22. By lifting or pressing down the handle 1, the drive assembly 22 is controlled to drive the second gripping member 212 toward or away from the first gripping member 211. Specifically, the wiping cloth is a thin nonwoven fabric. In this embodiment, by lifting the handle 1 and moving the second gripping member 212 away from the first gripping member 211, the mop base plate 2 is placed on the wiping cloth, and by pressing down the handle 1 and moving the second gripping member 212 toward the first gripping member 211, the wiping cloth is held between the first gripping member 211 and the second gripping member 212. When releasing, the handle 1 is lifted, and the second gripping member 212 separates from the first gripping member 211, allowing the wipe to fall; when gripping, part of the wipe is pinched between the first gripping member 211 and the second gripping member 212, achieving the purpose of gripping the wipe. According to the above solution, a drive assembly 22 is provided for connecting the second gripping member 212 and the handle 1, and by lifting or pushing down the handle 1, the second gripping member 212 can be controlled to move closer to or farther away from the first gripping member 211, thereby gripping the wipe when moved closer and releasing the wipe to release the wipe, resulting in a simple structure and easier wipe replacement.Furthermore, the mop base plate 2 is provided with a cover 23 connected to the handle 1 and the first gripping member 211 which is detachably connected to the side of the mop base plate 2 away from the handle 1, and a protrusion opening 231 is provided on the side of the cover 23 for the second gripping member 212 to protrude.

[0046] Furthermore, the second gripping members 212 are provided at opposite ends of the first gripping members 211 located in the same plane, and the drive assembly 22 can move the two second gripping members 212 toward or away from each other along the planar direction of the first gripping members 211, making it easier to change wipes. The drive assembly 22 further includes a link mechanism 222 connected between one end of the mop base plate 2 adjacent to the handle 1 and the second gripping members 212, a resilient member 223 acting between the two second gripping members 212 and tending to move the two second gripping members 212 in opposite directions, and a pressing member 224 connected to one end of the handle 1 adjacent to the mop base plate 2 and acting on the link mechanism 222 to drive the two second gripping members 212 toward each other. Preferably, a first toothed zone 211-1 is provided at the end of the first gripping member 211 facing the second gripping member 212, and a second toothed zone 212-2 is provided at the end of the second gripping member 212 facing the first gripping member 211, and the first toothed zone 211-1 and the second toothed zone 212-2 are offset from each other to improve the firmness of the mop cloth grip. Specifically, the handle 1 includes an outer rod 11 connected to the mop base plate 2 and an inner rod 12 slidably fitted within the outer rod 11, and the outer rod 11 is fixed to the mop base plate 2. The pressing member 224 is connected to the lower end of the inner rod, and the pressing member 224 can be moved up and down synchronously by lifting or pressing down the inner rod 12. Then, after the inner rod 12 is lifted to move the pressing member 224 upward, the pressing member 224 disengages from the link mechanism 222, whereby the repulsive force of the elastic member 223 urges the two second gripping members 212 in a direction away from each other, causing the second gripping members 212 to move away from the first gripping member 211, loosening the dust cloth and making it easier to replace the dust cloth.After the inner rod 12 is pushed down to move the pressing member 224 downward, the pressing member 224 applies force to the link mechanism 222 to move the two second gripping members 212 toward each other, bringing the second gripping member 212 toward the first gripping member 211 and locking the first gripping member 211 and the second gripping member 212, thereby improving the robustness of the rag grip.

[0047] Furthermore, the link mechanism 222 includes a first link 222-1 hingedly connected to each of the two second gripping members 212, and two second links 222-2 hingedly connected to the other ends of the two first links 222-1, respectively, and the other ends of the two second links 222-2 are hingedly connected to one end of the mop base plate 2 adjacent to the handle 1. After the handle 1 is lifted, the pressing member 224 is released from the link mechanism 222, and the two second gripping members 212 are moved in directions away from each other by the repulsive force of the elastic member 223. At the same time, the hinge connection portion between the first link 222-1 and the second link 222-2 is relatively expanded upward and outward until the first link 222-1 and the second link 222-2 are positioned on the same straight line, and at this time, the second gripping member 212 is separated from the first gripping member 211 to the maximum extent. After the handle 1 is pressed down, the pressing member 224 acts on the link mechanism 222 to relatively move the hinge connection portion between the first link 222-1 and the second link 222-2 inward and downward direction, driving the two second gripping members 212 to move in a direction toward each other, at which time the second gripping member 212 approaches the first gripping member 211 as close as possible, and at the same time, the first link 222-1 and the second link 222-2 are in a substantially vertical state. Preferably, there are two sets of link mechanisms 222, which are arranged symmetrically with respect to the handle 1. There are two elastic members 223, which are arranged symmetrically with respect to the handle 1.Each of the second gripping members 212 comprises an elongated gripping rod 212-3 provided with the second toothed zone 212-2, and an extension rod 212-4 extending from the gripping rod 212-3 toward the other second gripping member 212. Each of the gripping rods 212-3 located on both sides of the handle 1 is provided with two extension rods 212-4. The connection between the extension rod 212-4 and the gripping rod 212-3 is provided with an abutment portion 212-5 for abutting against the elastic member 223. The extension rod 212-4 further has an accommodating slot 212-4a that is connected to the abutment portion 212-5 and accommodates the elastic member 223. The elastic member 223 is disposed in the accommodating slot 212-4a of the two extension rods 212-4, and both ends thereof abut against the two abutment portions 212-5, respectively. When the first gripping member 211 and the second gripping member 212 are in a locked state, the elastic member 223 stores compression energy. After the pressing member 224 is released from the link mechanism 222, the repulsive force of the stored compression energy in the elastic member 223 causes the two second gripping members 212 to move away from each other, and the second gripping members 212 move away from the first gripping member 211, loosening the cleaning cloth and making it easier to replace the cleaning cloth.

[0048] Furthermore, the mop bottom plate 2 is provided with a movement groove 25 for moving the pressing member 224 along the movement direction of the handle 1, and the movement groove 25 is provided with a first limiting portion 251 and a second limiting portion 252 at both ends in the movement direction of the handle 1. The first limiting portion 251 is provided close to the handle 1, and the second limiting portion 252 is provided close to the mop bottom plate 2. When the handle 1 is lifted until the pressing member 224 abuts against the first limiting portion 251, the second gripping member 212 moves in a direction away from the first gripping member 211 to the maximum, and when the handle 1 is moved downward until the pressing member 224 abuts against the second limiting portion 252, the second gripping member 212 comes close to the first gripping member 211 to the maximum. Preferably, a locking structure (not shown) is further provided between the outer wall of the inner rod 12 and the inner wall of the outer rod 11, and when the pressing member 224 moves the inner rod 12 downward until it is pressed against the second limiting portion 252, the locking structure locks the inner rod 12 and the outer rod 11 and restricts the sliding movement of the inner rod 12 relative to the outer rod 11, and at this time, the second gripping member 212 is maximally close to the first gripping member 211, i.e., the first gripping member 211 and the second gripping member 212 are in a locked state, and after lifting the inner rod 12, the inner rod can release the locked state of the locking structure, so that the inner rod 12 can move upward along the outer rod 11. Specifically, the moving groove 25 communicates with the internal cavity of the mop base plate 2, and the pressing member 224 includes a pressing portion 224-1 that extends into the moving groove 25 and presses against the link mechanism 222. The pressing member 224 further includes a sliding portion 224-2 located directly below the inner rod 12, and the mop base plate 2 is provided with a chute 26 for the sliding portion 224-2 to slide along, and the sliding portion 224-2 is always positioned on the chute 26 to more stably move the pressing member 224. The sliding portions 224-2 located at both ends of the inner rod 12 are each provided with two pressing portions 224-1, which respectively apply force to the link mechanism 222.At the same time, the pressing portion 224-1 moves along the outer wall of the second link 222-2 when the link mechanism 222 expands and contracts.
