[0041] It is to be understood that the embodiments described herein are for illustrative purposes and that various modifications or changes in light thereof will be suggested to persons skilled in the art and are to be included within the spirit and purview of this application and scope of the appended claims. The description herein is presented to enable any person skilled in the art to make and use the application.

[0042] It is also to be understood that the following description is only illustrative of the principles of the application. Other arrangements can be devised that are functionally equivalent to those described herein without departing from the spirit and scope of the application as set forth in the appended claims.

[0043] Furthermore, in the following description, numerous specific details are set forth in order to provide a thorough understanding of the examples. However, it will be recognized by one skilled in the art that an embodiment can be practiced without these specific details.

[0044] The technical solutions provided by the embodiments of the present application are described below with reference to the drawings.

[0045] Referring to Figures 1 to 13 The mop plate 1 is symmetrically installed with the first cloth clamping members 3 on both sides in the width direction, and is symmetrically installed with the second cloth clamping members 4 on both sides in the length direction; the two first cloth clamping members 3 are arranged oppositely, and the two second cloth clamping members 4 are arranged oppositely, wherein the mop plate 1 is in a rectangular shape, and the four cloth clamping members are arranged around the mop plate 1, and the four sides of the mop cloth are clamped by the four cloth clamping members, so that the clamping is stable and reliable and is not easy to loosen.

[0046] Referring to Figure 1 and Figure 2 The driving seat 5 is movably installed on the mop plate 1 and is installed at the center position of the mop plate 1. The mop rod 2 is drivingly connected with the driving seat 5, the first cloth clamping member 3 and the second cloth clamping member 4 are respectively drivingly connected with the driving seat 5, and the driving seat 5 drives the first cloth clamping member 3 and the second cloth clamping member 4 to move in a rotating or up-and-down moving manner; in use, the mop rod 2 drives the driving seat 5 to rotate or move, and the driving seat 5 drives the first cloth clamping member 3 and the second cloth clamping member 4 to expand or shrink simultaneously.

[0047] In some embodiments, as Figure 14As shown, the drive seat 5 is a gear drive seat, and the first fabric clamping member 3 is provided with a rack that meshes with the gear. During operation, the drive seat 5 rotates, thereby driving the first fabric clamping member 3 to move via the rack. The drive seat 5 can also be a cam drive seat, and the first fabric clamping member 3 is provided with a groove surface that engages with the rotation of the cam. (See reference...) Figure 15 and Figure 16 The drive seat 5 can also be a movable drive seat. The first fabric clamping member 3 is provided with an inclined surface for driving, or the first fabric clamping member 3 is connected to the movable drive seat through a connecting rod for driving. When the inclined surface driving is used, the movable drive seat is provided with a first inclined pressing surface, and the first fabric clamping member 3 is provided with a matching second inclined pressing surface. When the movable drive seat presses down, it can drive the first fabric clamping member 3 to move. When the connecting rod driving is used, when the movable drive seat slides in the vertical direction, it can drive the first fabric clamping member 3 to move through the connecting rod.

[0048] In some embodiments, such as Figure 3 as well as Figures 5 to 7 As shown, a drive frame 6 is slidably installed inside the mop board 1, located between two first cloth clamping parts 3. The drive frame 6 is used to drive the first cloth clamping parts 3 to extend or retract. A detonator 501 is provided on one side of the drive seat 5, thus forming a cam drive seat. A linear guide groove 601 adapted to the detonator 501 is provided on the drive frame 6, and the detonator 501 is placed in the linear guide groove 601. Multiple pairs of first oblique guide grooves 602 are spaced apart along a straight direction on the drive frame 6. A first oblique guide post 301 adapted to the first oblique guide groove 602 is provided on the first cloth clamping part 3, and the first oblique guide post 301 is placed in the corresponding first oblique guide groove 602. When clamping the cloth, the drive seat 5 rotates, and the drive seat 5 drives the drive frame 6 to slide through the detonator 501. The drive frame 6 drives the first cloth clamping part 3 to extend or retract through the first oblique guide post 301. The structure employs multiple pairs of first inclined guide posts 301, which work together with the first inclined guide groove to drive the first fabric clamping component to have multiple clamping points. When the length of the first fabric clamping component is large, if it is clamped by driving from both ends (i.e., clamping points on both sides), the first fabric clamping component is prone to deformation. This structure, with multiple clamping points, can prevent the first fabric clamping component from deforming and make the fabric clamping more reliable.

[0049] In some embodiments, such as Figure 3 , Figure 5 , Figure 9 and Figure 10 As shown, a second inclined guide post 302 is provided at one end of the first fabric clamping component 3 near the second fabric clamping component 4. A second inclined guide groove 401, adapted to the second inclined guide post 302, is provided on the second fabric clamping component 4, with the second inclined guide post 302 positioned within the second inclined guide groove 401. Simultaneously with the first fabric clamping component 3 extending or retracting, the first fabric clamping component 3 drives the second fabric clamping component 4 to extend or retract via the second inclined guide post 302, ensuring that both the first and second fabric clamping components 3 and 4 can extend or retract simultaneously, making operation simpler.

[0050] In some embodiments, as shown in Figure 5 , Figure 7 and Figure 8 , the first cloth clamping member 3 and / or the second cloth clamping member 4 comprises a support arm 31 slidingly installed in the mop plate 1 and a cloth clamping jaw 32 hingedly connected to the end of the support arm 31, the cloth clamping jaw 32 being located on the outer side of the support arm 31. In this embodiment, in order to simplify the structure, the first cloth clamping member 3 is designed in a split type comprising the support arm 31 and the cloth clamping jaw 32, and the second cloth clamping member 4 is designed in a one-piece type and can only slide. The bottom of the mop plate 1 is provided with a wiping plate 7, and when the first cloth clamping member 3 is unfolded towards the outer side, the cloth clamping jaw 32 is rotated towards the wiping plate 7. With this structure, the cloth clamping jaw can move towards the side of the wiping plate 7, so that after the wiping plate 7 of the mop plate is placed on the external wiping cloth, the cloth clamping jaw can contact the wiping cloth, and when the cloth is clamped inwards, the wiping cloth is clamped at the stepped portion 701 of the wiping plate 7, so that people do not need to worry about bumping into the cloth clamping jaw during daily mopping.

[0051] In some embodiments, as shown in Figure 7 , Figure 12 and Figure 13 , a plurality of guide protrusions 101 are arranged on the inner wall side end of the mop plate 1 in a straight direction, and the guide protrusions 101 are configured to always provide a pushing force to the cloth clamping jaw 32 to move it towards the side of the wiping plate 7 when the first cloth clamping member 3 is unfolded towards the outer side. A plurality of avoidance grooves 321 corresponding to the guide protrusions 101 are arranged on the cloth clamping jaw 32, and when the cloth clamping jaw 32 is retracted, the guide protrusions 101 are placed in the avoidance grooves 321. With this structure, when the cloth clamping jaw is unfolded, the guide protrusions will come out of the avoidance grooves, at which time the guide protrusions will press down the cloth clamping jaw, so that the cloth clamping jaw swings relative to the support arm. By driving the cloth clamping jaw to swing through the guide protrusions, the structure is simple, the driving is reliable, and the guide protrusions can be designed in a one-piece structure with the mop plate; when the cloth clamping jaw is retracted into the mop plate, the guide protrusions are placed in the avoidance grooves again to avoid, which is a clever design.

[0052] In some embodiments, as shown in Figure 11 and Figure 12 , a plurality of pairs of first guide buckles 102 for guiding the first cloth clamping member 3 and a plurality of pairs of second guide buckles 103 for guiding the second cloth clamping member 4 are arranged on the inner wall of the mop plate 1; a plurality of guide grooves 603 are arranged on the driving frame 6, and a plurality of guide protrusions 104 adapted to the guide grooves 603 are arranged on the inner wall of the mop plate 1, and the guide protrusions 104 are placed in the guide grooves 603.

[0053] In some embodiments, as shown in Figure 1 , Figure 3 and Figure 4As shown, mop rod 2 includes outer rod 21 hinged with mop plate 1, inner rod 22 slidably mounted in outer rod 21, and spiral rod 23 rotatably mounted in inner rod 22, lower end of spiral rod 23 is hinged with driving seat 5, lower end of inner rod 22 is mounted with screw sleeve 24 matched with spiral rod 23. When clamping cloth, pull up inner rod 22, inner rod 22 drives spiral rod 23 to rotate through screw sleeve 24, spiral rod 23 drives driving seat 5 to rotate, driving seat 5 drives first cloth clamping part 3 and second cloth clamping part 4 to expand simultaneously; then place wiping plate on mop cloth, press down inner rod 22, inner rod 22 drives spiral rod 23 to rotate reversely through screw sleeve 24, driving seat 5 rotates reversely, driving seat 5 drives first cloth clamping part 3 and second cloth clamping part 4 to shrink reversely and clamp mop cloth.

[0054] In some embodiments, as shown in Figure 1 , Figure 3 and Figure 4 , annular boss 231 is arranged on spiral rod 23, and a plurality of elastic clamping plates 241 capable of clamping annular boss 231 are arranged on screw sleeve 24 at equal intervals; annular boss 231 is clamped by elastic clamping plate 241, so that inner rod is limited during mopping, and driving seat 5 is prevented from being mis-rotated; when clamping cloth, if the pulling force is greater than the clamping force of elastic clamping plate 241, elastic clamping plate 241 is disengaged from annular boss 231, and inner rod can be pulled out. Outer rod 21 is hinged with mop plate 1 through outer hinge seat 8, and driving seat 5 is hinged with spiral rod 23 through inner hinge seat 9, inner hinge seat 9 is located inside outer hinge seat 8.

[0055] In some embodiments, as shown in Figure 2 , Figure 3 , Figure 8 and Figure 10 , outer side end of first cloth clamping part 3 and second cloth clamping part 4 is provided with clamping part, and periphery of wiping plate 7 is provided with stepped part 701 corresponding to clamping part; taper teeth 402 are arranged on clamping part at intervals along straight line direction, and triangular teeth 403 are arranged on one side of taper teeth 402 along straight line direction, taper teeth 402 and triangular teeth 403 are adopted to cooperate, and mop cloth is clamped more stably.

[0056] In the specification, the same or similar parts among various embodiments can be referred to each other, and each embodiment focuses on the difference from other embodiments.

[0057] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
