[0002] Currently, for a push-type collodion mop, a user can hold the mop handle and pull the mop fork to fold the two collodion mounting plates in half to clean or dehydrate the collodion. That is, in order to achieve cleaning or dehydration, the mop fork and the mop handle need to move flexibly with each other.

[0003] However, the collodion mop needs to be in contact with the ground during use, and there is friction between the ground and the collodion. When the friction is large, the user pulls the entire mop through the mop plate, which will cause relative movement between the mop rod and the mop fork. This relative movement will cause the two collodion mounting plates to fold in half, that is, the collodion will be deformed, affecting the user's normal use.

[0004] Therefore, how to provide a mop head assembly and a mop having the same that can prevent the collodion from being deformed during use has become a technical problem that those skilled in the art urgently need to solve. Summary of the Invention

[0126] According to an embodiment of the present invention, in one aspect, the present invention provides a mop head assembly including a mounting structure 10 and a switch assembly 30; the mounting structure 10 is used to mount a wiping structure 20; the mounting structure 10 includes a movable portion 12 and a fixed portion 11 that are movably connected; the movable portion 12 is configured to move relative to the fixed portion 11 to enable the mounting structure 10 to switch between a water squeezing state and a mopping state; the movable portion 12 is configured to move to bend the wiping structure 20 to squeeze water in the water squeezing state; the movable portion 12 is configured to unfold the wiping structure 20 in the mopping state; the switch assembly 30 is configured to lock and unlock the movable portion 12 and the fixed portion 11 in the mopping state; when the switch assembly 30 locks the movable portion 12 and the fixed portion 11, the fixed portion 11 and the movable portion 12 allow the wiping structure 20 to be fully unfolded. The present application uses the switch assembly 30 to lock and unlock the movable portion 12 and the fixed portion 11 in the mopping state, allowing the wiping structure 20 to be fully unfolded, while locking the fixed portion 11 and the movable portion 12 in this state during mopping, thereby preventing the wiping structure 20 from deforming during use. In this application, fully unfolded means without any folds or wrinkles, etc. The wiping structure 20 can be a collodion, and fully unfolded means that the collodion is flat and not deformed; the wiping structure 20 can also be a rag, and fully unfolded means that the rag is flat.

[0127] In an optional embodiment, when the switch assembly 30 locks the movable portion 12 and the fixed portion 11, the surface of the mounting structure 10 facing the wiping structure 20 forms a planar structure. The surface of the mounting structure 10 facing the wiping structure 20 forms a plane, and the wiping structure 20 is mounted on this plane. That is, the surfaces of the movable portion 12 and the fixed portion 11 facing the wiping structure 20 are on the same surface. Therefore, when mopping the floor, the wiping structure 20 is always fully extended and does not deform.

[0128] In an optional embodiment, when the switch assembly 30 locks the movable portion 12 and the fixed portion 11, the fixed portion 11 and the movable portion 12 are in the same plane, that is, the surfaces of the movable portion 12 and the fixed portion 11 facing the wiping structure 20 are on the same surface. In this manner, the wiping structure 20 remains fully extended during mopping and does not deform. When mopping, the switch assembly 30 locks the movable portion 12 and the fixed portion 11 so that the surfaces remain parallel to the horizontal plane. This prevents relative movement between the movable portion 12 and the fixed portion 11, thereby preventing deformation of the wiping structure 20.

[0129] In an optional embodiment, when the switch assembly 30 locks the movable portion 12 and the fixed portion 11, the mounting structure 10 forms a plate-like structure. That is, the surfaces of the movable portion 12 and the fixed portion 11 facing the wiping structure 20 are on the same surface. Therefore, the wiping structure 20 is always fully extended during mopping and does not deform. This prevents relative movement between the movable portion 12 and the fixed portion 11, thus preventing deformation of the wiping structure 20.

[0130] In an optional embodiment, the switch assembly 30 includes a movable structure 31 having a limit position for restricting the movement of the movable portion 12 relative to the fixed portion 11 and a release position for releasing the movable portion 12 from the fixed portion 11. The movable structure 31 is configured to move between the limit position and the release position to unlock or lock the fixed portion 11 and the movable portion 12. The movable portion 12 and the fixed portion 11 are locked or unlocked by the movement of the movable structure 31 on the mounting structure 10, and unlocking and locking are convenient and effective. For example, the movable structure 31 can be moved by sliding the sliding structure 312, rotating the rotating structure 311, or rolling the rolling structure, among other movable methods. If the rolling structure is a rolling structure, a ball can be rolled between the fixed portion 11 and the movable portion 12. For example, a groove can be provided between the fixed portion 11 and the movable portion 12, and the groove can be connected to a channel on the fixed portion 11 or the movable portion 12. When the ball rolls into the groove, the two are locked, and when the ball rolls into the channel, the two are unlocked.

[0131] In an optional embodiment, the movable structure 31 is provided on one of the movable portion 12 and the fixed portion 11; a limiting slot 60 is provided on the other of the fixed portion 11 and the movable portion 12. The movable structure 31 is configured to move between the fixed portion 11 and the movable portion 12, thereby extending into or out of the limiting slot 60. The movable portion 12 and the fixed portion 11 are unlocked or locked by extending the movable structure 31 into or out of the limiting slot 60. The cooperation between the movable portion 12 and the limiting slot 60 can ensure more stable locking and more thorough unlocking, thereby improving the switching effect.

[0132] In an optional embodiment, the movable structure 31 includes a rotating structure 311; the rotating structure 311 is rotatably disposed on one of the fixed portion 11 and the movable portion 12; the rotating structure 311 is configured to rotate to a corresponding position on the other of the fixed portion 11 and the movable portion 12 during mopping, thereby locking the fixed portion 11 and the movable portion 12. The rotating structure 311 rotates to unlock the fixed portion 11 and the movable portion 12. When the entire rotating structure 311 is completely located on the movable portion 12 or the fixed portion 11, both are unlocked. When a portion of the rotating structure 311 is located on the fixed portion 11 and the other portion is located on the movable portion 12, the relative movement between the two can be restricted, thereby locking the movable portion 12 and the fixed portion 11.

[0133] In an optional embodiment, the rotating structure 311 is configured to extend from the fixed portion 11 to the movable portion 12 in the restricted position; the rotating structure 311 is configured to be located only on the fixed portion 11 or the movable portion 12 in the released position. The fixed portion 11 and the movable portion 12 are unlocked by rotating the rotating structure 311. When the entire rotating structure 311 is completely located on the movable portion 12 or the fixed portion 11, both are unlocked. When a portion of the rotating structure 311 is located on the fixed portion 11 and another portion is located on the movable portion 12, the relative movement between the two can be restricted, thereby locking the movable portion 12 and the fixed portion 11. The rotating structure 311 can rotate around a fixed rotation center.

[0134] In an optional embodiment, the rotating structure 311 is arranged on the curved or bent side of the mounting structure 10 in the water squeezing state, and the rotating structure 311 is in contact with the corresponding surface of the mounting structure 10 when it is in the limiting position. The rotating structure 311 is arranged on the curved or bent side of the mounting structure 10 in the water squeezing state, that is, the rotating structure 311 is located on the side of the movable part 12 and the fixed part 11 relative to the movable direction. In this way, the rotating structure 311 can be stopped on one side of the movable direction, thereby limiting its movement. The limiting effect is good, the structure is simple, and it is easy to install. When the rotating structure 311 is in the limiting position, it is in contact with the corresponding surface of the mounting structure 10, which can completely limit the movement between the two and prevent relative movement between the two. The rotating structure 311 can be a special-shaped structure, or it can be an elliptical shape, or it can be a circular shape with two parallel edges cut off.

[0135] In an optional embodiment, the rotating structure 311 includes a rotating cylinder 3111 and a strip-shaped rotating portion 3112; the strip-shaped rotating portion 3112 is fixed to the rotating cylinder 3111; the rotating cylinder 3111 is rotatably connected to the mounting structure 10, and the rotating cylinder 3111 is used to drive the strip-shaped rotating portion 3112 to rotate so that the strip-shaped rotating portion 3112 fits the corresponding surface of the mounting structure 10 when in the limited position. The strip-shaped rotating portion 3112 is driven to rotate by rotating the rotating cylinder 3111 to lock or unlock the fixed portion 11 and the movable portion 12, making the operation more convenient. The strip-shaped rotating portion 3112 can be a rotating rod, a sheet-like strip structure, or an irregular structure, as long as the overall length and width are sufficient, such as an elliptical shape.

[0136] In an optional embodiment, the movable structure 31 includes a sliding structure 312 that slides between the movable portion 12 and the fixed portion 11 to switch between a restricted position and a released position. The sliding structure 312 slides to unlock or lock the fixed portion 11 and the movable portion 12, providing a more flexible installation method and simple operation. The sliding structure 312 can be any shape, such as rectangular, spherical, or hemispherical.

[0137] In an optional embodiment, an abutment structure is provided on one of the movable portion 12 and the fixed portion 11, and an elastic structure 50 abuts between the sliding structure 312 and the abutment structure. To reset the movement of the sliding structure 312 using the elastic structure 50, the sliding structure 312 only needs to be operated in one of the unlocked and locked states. In the other state, the elastic structure 50 will reset the sliding structure 312. The elastic structure 50 may be a spring, an elastic block, or an elastic gasket.

[0138] In an optional embodiment, the elastic structure 50 includes a spring; the spring is mounted on the sliding structure 312; or, a sliding rod is provided on one of the movable portion 12 and the fixed portion 11, and the sliding structure 312 is slidably mounted on the sliding rod 3122; the spring is mounted on the sliding rod 3122. Directly mounting the spring on the sliding structure 312, or installing the sliding rod 3122 and then mounting the spring on the sliding rod 3122, provides a more stable installation method and prevents the spring from detaching from the movable structure 31. The cross-sectional shape of the sliding rod 3122 can be any shape, such as rectangular, circular, or elliptical.

[0139] In an optional embodiment, the sliding structure 312 is disposed on the surface of the mounting structure 10 facing away from the wiping structure 20. Mounting the sliding structure 312 on the surface allows the user to directly operate it and visually inspect its status, making operation more convenient. Furthermore, if the sliding structure 312 or the elastic member 70 is damaged, repair or replacement is more convenient.

[0140] In an optional embodiment, a first clamping member is provided on the sliding structure 312, and a second clamping member adapted to the first clamping member is provided on the mounting structure 10; the first clamping member is used to engage with the second clamping member when in the limit position. When the sliding structure 312 moves to the release position, the first clamping member engages with the second clamping member, and when the sliding structure 312 moves to the release position, the first clamping member engages with the second clamping member, thereby fixing the sliding structure 312 in a specific position, so that the movable portion 12 and the fixed portion 11 can move relative to each other. In this way, there is no need to manually control the sliding structure 312 during the water squeezing process, which does not affect the water squeezing. When mopping the floor, the first clamping member and the second clamping member can be manually disengaged from each other, so that the sliding structure 312 moves to the limit position.

[0141] In an optional embodiment, the sliding structure 312 is disposed within the mounting structure 10. The switch assembly 30 further includes a first switch structure 32, which extends from the mounting structure 10 at the location of the sliding structure 312. The first switch structure 32 is disposed on one side of the sliding structure 312 and is used to apply a force to the sliding structure 312, causing it to slide. Mounting the sliding structure 312 within the mounting structure 10 makes it more discreet and does not affect the aesthetics of the mop head assembly. The extended first switch structure 32 provides for easier operation. A user can control the state of the sliding structure 312 by operating the first switch structure 32.

[0142] In an optional embodiment, the first switch structure 32 is provided with a first inclined surface during movement. During movement, the first inclined surface is used to apply a force to the sliding structure 312, pushing the sliding structure 312 to move, thereby unlocking or locking the fixed portion 11 and the movable portion 12. The first switch structure 32 is configured to move in a first direction to apply a force to the sliding structure 312. The first inclined surface is provided on the first switch structure 32 and is inclined relative to the first direction. During movement, the first inclined surface contacts the sliding structure 312. Due to the provision of the first inclined surface, when the first switch structure 32 moves in the first direction, its position relative to the sliding structure 312 in the second direction changes, thereby causing the sliding structure 312 to move in the second direction, thereby unlocking or locking the fixed portion 11 and the movable portion 12. Due to the provision of the first inclined surface, when the first switch structure 32 moves in the first direction, its position relative to the sliding structure 312 in the second direction changes, thereby causing the sliding structure 312 to move in the second direction, thereby unlocking or locking the fixed portion 11 and the movable portion 12. The first direction is perpendicular to the second direction; the first direction coincides with the extension direction of the mop handle, while the second direction indicates the direction in which the movable portion moves toward or away from the fixed portion. When mopping, the first direction is vertical, while the second direction is horizontal. The first inclined surface can push the sliding structure 312 of any shape; in different active positions, the sliding structure 312 contacts different locations on the first inclined surface.

[0143] In an optional embodiment, the first switch structure 32 includes an L-shaped structure, wherein the long side of the L-shaped structure extends out of the mounting structure; the end surface of the short side of the L-shaped structure forms a first inclined surface; and the sliding structure 312 has a second inclined surface 3121 corresponding to the first inclined surface. When the first switch structure 32 moves in the first direction, due to the change in the position of the first switch, the inclined surface at the corresponding position of the sliding structure 312 also changes in the second direction, so that the sliding structure 312 can move in the second direction. After the movement, the contact position between the first inclined surface and the second inclined surface 3121 changes, but the two inclined surfaces are still in contact and fit together. The present application reduces the wear between the two inclined surfaces through the relative cooperation of the two inclined surfaces, making the mechanism cooperate more smoothly.

[0144] In an optional embodiment, the sliding structure 312 includes a sliding rod; a first limit plate and a second limit plate vertically connected to each other are provided inside the mounting structure; the sliding structure is provided on the first limit plate; a through hole is provided on the second limit plate; the first end of the sliding rod is movably provided in the through hole; when the sliding structure 312 has a second inclined surface 3121 corresponding to the first inclined surface, the second end face of the sliding rod forms a second inclined surface; the sliding rod is used to pass through the through hole to lock the fixed part 11 and the movable part 12, or retract into the through hole to unlock the fixed part 11 and the movable part 12.

[0145] In an optional embodiment, when a limiting slot 60 is provided on the other of the fixed portion 11 and the movable portion 12, the sliding rod is adapted to the limiting slot 60; the sliding rod passes through the through hole and can enter the limiting slot 60 to lock the fixed portion 11 and the movable portion 12; the sliding rod retracts into the through hole to exit the limiting slot 60, thereby unlocking the fixed portion 11 and the movable portion 12. The sliding structure 312 can pass through the through hole from one of the fixed portion 11 and the movable portion 12 to the corresponding position of the other of the fixed portion 11 and the movable portion 12, or it can retract into the through hole to avoid the other. In this application, the movement of the sliding structure 312 is limited by the through hole, which can make the movement of the sliding structure 312 smoother and the path more accurate.

[0146] In an optional embodiment, when an abutment structure is provided on one of the movable part 12 and the fixed part 11, an elastic structure 50 abuts against the sliding structure 312 and the abutment structure, and the sliding structure 312 includes a sliding rod; a first limiting plate and a second limiting plate vertically connected to each other are provided inside the mounting structure, the second limiting plate forms an abutment structure; a limiting part is provided on the sliding rod, and the elastic structure 50 has a sleeve hole; the elastic structure 50 is sleeved on the sliding rod through the sleeve hole, and abuts between the limiting part and the second limiting plate.

[0147] In an optional embodiment, the sliding structure 31 has a back side and a front side arranged opposite to each other; a locking block 34 is provided on the front side; the first switch structure 32 is located on the back side of the sliding structure 312, and the first switch structure 32 is used to apply a force to the back side of the sliding structure 312, so that the sliding structure 312 drives the locking block 34 to move between the fixed part 11 and the movable part 12, thereby unlocking or locking the fixed part 11 and the movable part 12.

[0148] In an alternative embodiment, when the sliding structure 312 has a second inclined surface 3121 corresponding to the first inclined surface, the second inclined surface is provided on the back surface. A groove can be cut on the back surface, and the second inclined surface can be provided on the peripheral wall of the groove, or a bump can be provided on the back surface, and the inclined surface can be provided on the bump.

[0149] In an optional embodiment, a transmission structure is provided on the back surface, with a second inclined surface on the surface of the transmission structure facing the first switch structure 32. The transmission structure can be a bump, which can be integrally formed with the back surface or formed by connecting two separate parts. This arrangement makes the two inclined surfaces more convenient to mate.

[0150] In an optional embodiment, the transmission structure has a longitudinal cross-section shaped as a right-angled trapezoid; the slanted waist of the right-angled trapezoid forms a second inclined surface; and the lower base of the trapezoid mates with the back surface. It can be considered that cutting an inclined surface on the bottom surface of a rectangular parallelepiped or cube to form the second inclined surface provides a more stable fit with the first inclined surface, preventing separation.

[0151] In an optional embodiment, a first mounting slot is provided on the front, and a second mounting slot is provided on one of the movable portion 12 and the fixed portion 11. The openings of the first and second mounting slots face each other. When an abutment structure is provided on one of the movable portion 12 and the fixed portion 11, and the elastic structure 50 abuts against the abutment structure, the second mounting slot forms an abutment structure, and the elastic structure 50 extends into the first and second mounting slots and abuts against the bottoms of the first and second mounting slots. This installation method provides a limiting effect on the elastic structure 50, preventing it from disengaging from the first and second mounting slots.

[0152] In an optional embodiment, when an abutting structure is provided on one of the movable portion 12 and the fixed portion 11, and the elastic structure 50 abuts between the sliding structure 312 and the abutting structure, two locking blocks 34 are provided, and the two locking blocks 34 are respectively provided on both sides of the elastic structure 50. The two symmetrically arranged locking blocks 34 can unlock or lock two symmetrical positions of the movable portion and the fixed portion, thereby preventing displacement between the two.

[0153] In an optional embodiment, a through hole is provided on one of the fixed part 11 and the movable part 12; when a limiting slot 60 is provided on the other of the fixed part 11 and the movable part 12, the locking block 34 is adapted to the limiting slot 60; the locking block 34 can pass through the through hole and enter and exit the limiting slot 60 to lock or unlock the fixed part 11 and the movable part 12, and the locking block 34 and the limiting slot 60 form a concave-convex matching structure, which can be snapped in more stably.

[0154] In an optional embodiment, a guide structure is provided on the sliding structure, a guide rail is provided within the mounting structure, and the guide structure is movably mounted on the guide rail. The guide structure may be a guide block, and the guide rail may be a guide groove; alternatively, the guide block may be a ball bearing, and the guide rail may be a guide groove; the guide rail may be a protruding guide bar, and the guide structure may be a structure with grooves. The sliding structure may be a sliding plate; the sliding plate may be a strip plate; two locking blocks 34 are provided at either end of the strip plate; and the elastic structure 50 is provided in the middle of the strip plate. The positions of the two guide structures at the ends of the strip structure may correspond to the positions of the two locking blocks 34, or they may be staggered.

[0155] In an optional embodiment, the guide structure includes a guide groove, and the guide rail includes a guide bar. The guide bar is disposed in the guide groove to guide the movement of the sliding structure. The guide groove moves on the guide bar, so that the movement trajectory of the sliding structure is restricted, allowing the locking block 34 to accurately enter and exit the limit groove 60.

[0156] In an optional embodiment, two guide structures are provided, and the two guide structures are located on both sides of the sliding structure. The two guide structures can be symmetrically arranged.

[0157] In an optional embodiment, when the switch assembly 30 further includes the first switch structure 32, a switch hole is defined in the movable portion 12, and the first switch structure 32 extends out of the switch hole. By extending the first switch structure 32 out of the switch hole, the first switch structure 32 is positioned outside the movable portion 12, allowing the switch assembly 30 to be controlled to be on or off by the first switch structure 32 extending from the movable portion 12.

[0158] In an optional embodiment, when the switch assembly 30 further includes a first switch structure 32, a passage is provided on the fixed portion 11, through which the first switch structure 32 can extend into the mop rod 40 to extend the mop rod 40. By extending the first switch structure 32 through the switch hole and being located outside the movable portion 12, the switch assembly 30 can be controlled to be on or off by the first switch structure 32 extending from the movable portion 12.

[0159] In an optional embodiment, the movable structure 31 includes a curved or bent section 313; the curved or bent section includes a first straight section perpendicular to the cross-section of the slot opening of the limiting slot 60; the first straight section is configured to extend into or out of the limiting slot 60. The movable structure of the curved or bent section controls the relationship between the remaining limiting slots, with the fixed portion and the movable portion being locked by engaging the curved or bent section within the limiting slot and unlocked by exiting the limiting slot. The curved or bent section 313 also includes a second straight section, which forms an angle with the direction in which the first straight section extends; and the first and second straight sections are connected by a circular arc transition.

[0160] In an optional embodiment, the first straight segment is configured to extend into the retaining groove 60 during the mopping state; the mounting structure 10 is configured to push the first straight segment out of the retaining groove 60 when an external force is applied to switch from the mopping state to the squeezing state. During squeezing, the user pushes the mop prongs to push the mounting structure 10 into the squeezing state. During this process, the external force applied by the user squeezes the first straight segment out of the retaining groove 60, thereby unlocking the fixed portion 11. After squeezing is completed, the movable portion 12 and the fixed portion 11 return to the mopping state in the absence of the external force, and the first straight segment extends into the retaining groove 60 to lock the fixed portion 11 and the movable portion 12.

[0161] In an optional embodiment, there are two movable portions 12, one on each side of the fixed portion 11. Each movable portion 12 is provided with a first curved or bent section 313 and a second curved or bent section 313. The switch assembly 30 further includes a connecting structure 3131 that connects the first curved or bent section 313 and the second curved or bent section 313. By controlling the two curved or bent sections 313 simultaneously, the two movable portions 12 can be unlocked or locked simultaneously.

[0162] In an optional embodiment, the connecting structure 3131 includes a fixed structure; a limiting hole 3133 is provided on one of the movable portion 12 and the fixed portion 11; and the switch assembly 30 further includes a limiting member 3132 connected to the fixed structure and movably disposed within the limiting hole 3133. The limiting member 3132 drives the fixed structure to move, thereby driving the movable structure 31 to move. As the limiting member 3132 moves within the limiting hole 3133, the movable structure 31 maintains a fixed trajectory and does not deviate from the trajectory.

[0163] In an optional embodiment, the fixed portion 11 includes a fixed cylinder 111 and a main body 112 that are connected to each other, and the movable portion 12 is movably arranged on one side of the main body 112; a fixed plate is arranged in the fixed cylinder 111, and the plate surface of the fixed plate is arranged parallel to the cross-section of the fixed cylinder 111; a limiting hole 3133 is provided in the fixed plate; the limiting member 3132 includes a limiting rod, a first end of the limiting rod is positioned in the limiting hole 3133; and the second end of the limiting rod is connected to the connecting structure 3131. The provision of the limiting rod can effectively limit the movement of the limiting rod. By providing a fixed plate in the fixed cylinder 111 and providing a limiting hole 3133 on the plate, the movement trajectory of the movable structure 31 is limited by the cooperation between the limiting rod and the limiting hole 3133.

[0164] In an optional embodiment, the connecting structure 3131 includes a curved surface structure, the convex surface of which is connected to the second end of the limiting rod, and the curved or bent section 313 is movably disposed within the concave surface of the curved surface structure. The provision of the curved surface structure allows the curved or bent section 313 to be more easily moved to the position of the movable portion 12 or retracted to the position of the fixed portion 11. The curved surface structure can be either gentle or steep.

[0165] In an optional embodiment, the curved structure includes an arc structure, a connecting portion is provided on the arc structure, the connecting portion is provided on at least one side of the extension direction of the arc structure, a connecting groove or a connecting hole is provided on one end of the curved or bent section 313, and the connecting portion is provided in the connecting groove or the connecting hole, which can limit the movement of the curved or bent section to a certain extent and prevent it from detaching from the arc structure.

[0166] In an optional embodiment, an annular elastic portion is sleeved on the limiting rod, and the annular elastic portion abuts between the fixed plate and the curved structure. When squeezing water, the user pushes the mop fork to push the mounting structure 10 to the squeezing state. In this process, the first straight segment is squeezed out of the limiting groove 60 due to the external force applied by the user, thereby unlocking the fixed portion 11 to move; after the squeezing is completed, the movable portion 12 and the fixed portion 11 lose the external force and return to the mopping state under the elastic force of the annular elastic portion, so that the first straight segment of the bent or curved segment 313 extends into the limiting groove 60 to lock the fixed portion 11 and the movable portion 12.

[0167] In an optional embodiment, the switch assembly 30 further includes a second switch structure connected to the curved or bent section 313 and extending outside the mounting structure 10. The second switch structure is configured to apply force to the curved or bent section 313, causing the first curved or bent section 313 and the second curved or bent section 313 to simultaneously extend or extend into the corresponding limiting slot 60. The second switch structure simultaneously controls the two curved or bent sections 313, thereby simultaneously unlocking the fixed portion 11 and the two movable portions 12, or simultaneously locking the fixed portion 11 and the two movable portions 12.

[0168] In an alternative embodiment, the connecting structure 3131 includes a transmission structure and a rotary switch. The transmission structure connects the first and second curved or bent sections 313. The rotary switch is configured to drive the transmission structure when rotated, thereby causing the first and second curved or bent sections 313 to simultaneously extend or retract into their corresponding retaining slots 60. Rotation of the rotary switch causes the first and second curved or bent sections 313 to move. The rotary switch extends from the mounting structure 10 for easy operation and control. The rotary switch extends outside the mounting structure 10 to form an exposed structure, allowing direct user access. A coaxial inverting structure can be installed internally to form a transmission structure. When the rotary switch is rotated, the two curved or bent sections 313 can be controlled to move in opposite directions, thereby simultaneously controlling the locking or unlocking of the two movable portions 12. Alternatively, a planetary gear can be installed internally to form the transmission structure. Two gears with different rotational directions within the planetary gear connect the first and second curved or bent sections 312, 313. Any method that allows for a first bend or kink section 313 and a second bend or kink section 313 may be used.

[0169] In an optional embodiment, the fixed portion 11 includes a fixed cylinder 111 and a main body 112 that are interconnected. The fixed cylinder 111 is configured to be mounted on the mop handle 40. The switch assembly 30 includes an elastic structure 50 that connects the fixed cylinder 111 and the movable portion 12. The elastic structure 50 connects the fixed cylinder 111 and the movable portion 12, thereby exerting an elastic force in an opposite direction on the movable portion 12. During the squeezing process, an external force is applied to bend or flex the movable portion 12. During the mopping state, the elastic structure 50 can offset the relative movement of the movable portion 12 and the fixed portion 11. The elastic structure 50 can be an elastic block, an elastic gasket, a spring, or the like.
