Description

Technical Field

[0001] The utility model relates to the technical field of household flat mops, in particular to a wiping cloth clamping structure. Background Art

[0002] Flat mops are commonly used cleaning tools in the home, mainly including a mop rod and a wiping body for wiping the floor, and a wiping cloth is installed at the bottom of the wiping body, and the wiping cloth is usually in the shape of a flat plate. Cloth-clamped mops are a type of flat mops. At present, some cloth-clamped mops with cloth-clamping function on the market have cloth-clamping claws coplanar with the wiping surface at the bottom of the wiping body. In actual use, the cloth-clamping claws that clamp the wiping cloth may directly contact the ground during mopping, causing wear and tear, which will also affect its aesthetics. Taking the Chinese utility model with the announcement number "CN219846427U" previously applied by the applicant as an example, it discloses a cloth-clamped mop that is convenient for replacing mops, and the cloth-clamped mop includes a mop rod and a mop bottom plate; the mop bottom plate is provided with a clamping assembly for clamping the mop; the clamping assembly includes a first clamping member fixed to an end of the mop bottom plate away from the mop rod, and a second clamping member movably connected to the mop bottom plate and can be close to or away from the first clamping member. Combined with its specification and drawings, the bottom of the second clamping members on both sides is designed to be coplanar with the bottom of the first clamping member. After the second clamping members clamp the mop, the bottom of the second clamping members is exposed to the ground so that it is in direct contact with the ground, causing wear when mopping the floor. Therefore, there are certain limitations in use.

[0003] In the prior art, for example, the Chinese invention patent with application number "201310227871.2" discloses a dust mop, including a mop rod and a drag plate connected to the mop rod, one side of the drag plate is provided with a mounting mechanism for mounting a dust cloth or dust paper, the mounting mechanism includes a mounting groove and a clamping device connected to the mounting groove, the clamping device is a hollow structure, and the surface includes a plurality of clamping grooves. The clamping device is provided on the upper end surface of the drag plate, and the dust cloth needs to be manually disassembled and installed, that is, the old dust cloth needs to be manually taken out from the clamping groove, and the new dust cloth needs to be partially inserted into the clamping groove, and the dust cloth replacement operation is inconvenient. Another example is the Chinese utility model patent with application number "200420082055.3", which discloses a mop cloth clamping structure, which includes a panel connected to the mop, and the panel is provided with a hinged cloth clamping claw with teeth on the outer side. The hinged cloth clamping claw also needs to be manually opened to replace the mop. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] The problem to be solved by the utility model is to provide a wiping cloth clamping structure, which realizes the clamping of the wiping cloth by cooperating with the cloth clamping claws of the cloth clamping mechanism through the guide plate. The operation is convenient and there is no need to touch the wiping cloth with hands. The cloth clamping claws can maintain a good gripping effect for wiping cloths with different surfaces and thicknesses, and can overcome the defects in the prior art.

[0006] (II) Technical solution

[0007] In order to solve the technical problem, the utility model provides a wiping cloth clamping structure, which can be applied to commonly used flat mops, desktop wipers, window wipers, blackboard erasers and other wiping tools; the clamping structure includes a wiping body; the bottom of the wiping body is a wiping surface, and the side end of the wiping body is movably equipped with a cloth clamping mechanism that can be unfolded or retracted to clamp the cloth, so that the cloth clamping mechanism has an unfolded state and a retracted cloth clamping state; the cloth clamping mechanism is slidably installed on the side of the wiping body away from the wiping surface (the cloth clamping mechanism after clamping the cloth is higher than the wiping surface), and the cloth clamping mechanism includes a support An arm and a cloth clamping claw connected to the supporting arm, the cloth clamping claw can move toward the side of the wiping surface; the cloth clamping claw is configured to make the cloth clamping claw move toward the side of the wiping surface synchronously during the overall extension of the cloth clamping mechanism, and the cloth clamping claw can abut against the wiping cloth to grasp the wiping cloth; the cloth clamping claw is connected to an elastic member, and the elastic member is configured to make the cloth clamping claw always have a movement tendency of swinging toward the side of the wiping surface, and when the supporting arm of the cloth clamping mechanism drives the cloth clamping claw to expand outward, the elastic member drives the cloth clamping claw to be lower than the wiping surface.

[0008] In this solution, the cloth clamping claw is driven to move toward the wiping cloth by the elastic member so that it can be lower than the wiping cloth, and the cloth clamping claw's cloth gripping force can be determined by the elastic force of the elastic member. Taking the commonly used cloth clamping mop as an example, in order to improve the cloth gripping effect, the traditional ordinary cloth clamping mop needs to press down the mop rod with force by hand, which will make the contact friction between the mop head and the wiping cloth too large, so that the cloth clamping claw cannot be retracted into the cloth clamping state (that is, the cloth clamping claw is also pressed down and abutted against the wiping cloth at this time, resulting in a situation where it cannot be reset, and when the force pressing down the mop rod is lighter, there will also be a situation where the wiping cloth cannot be gripped). In this solution, after placing the wiping body on the wiping cloth, the cloth clamping claw can be pressed down by the elastic member to move toward the side of the wiping cloth and abut against the wiping cloth without applying a lot of pressure, so that the cloth can be easily clamped, and the elastic member of the cloth clamping claw can make the cloth clamping claw always maintain an appropriate gripping force with the wiping cloth, and can maintain a good gripping effect according to different surfaces and different thicknesses of wiping cloth.

[0009] In some embodiments, a guide plate is provided on the back of the wiping surface. When the cloth clamping mechanism is in the unfolded state, the cloth clamping mechanism extends outward, and the cloth clamping claws are unfolded outward and downward along the guide plate simultaneously. At this time, the cloth clamping claws are lower than the wiping surface. When clamping the cloth, the wiping body is abutted against the wiping cloth, and the driving mechanism controls the cloth clamping mechanism to switch from the unfolded state to the retracted cloth clamping state, and the cloth clamping claws drive the wiping cloth to retract inward along the guide plate and reset. The guide plate can keep the cloth clamping claws in contact with the wiping cloth to avoid separation from the wiping cloth during the retraction of the cloth clamping claws. At the same time, the guide plate moves the cloth clamping claws away from the bottom surface (the wiping body contacts the bottom surface of the wiping cloth when clamping the cloth), so that the wiping cloth completely covers the bottom surface of the wiping body.

[0010] In some embodiments, the clamping structure further includes a driving mechanism, which drives the cloth clamping mechanism to extend and retract, so that the mechanism switches between an expanded state and a retracted cloth clamping state.

[0013] In some embodiments, the cloth clamping claw is hingedly mounted on the support arm so as to rotate up and down; when the cloth clamping mechanism is in the expanded state, the outer end of the cloth clamping claw (for gripping the wiping cloth) is lower than the wiping surface; when the cloth clamping mechanism is in the retracted cloth clamping state, the cloth clamping claw that clamps the wiping cloth is higher than the wiping surface, and the cloth clamping mechanism enables the wiping cloth to completely wrap around the wiping surface in the front-to-back direction, thereby achieving a good wiping effect.

[0014] In some embodiments, the elastic member comprises a torsion spring installed at the hinge of the cloth clamping claw, one end of the torsion spring is installed on the support arm, and the other end is placed on the cloth clamping claw.

[0015] In some embodiments, the cloth clamping claw includes convex teeth arranged at equal intervals; the convex teeth are arranged in a staggered distribution, and the staggered convex teeth are configured to firmly grasp the wiping cloth.

[0016] In some embodiments, the guide plate is provided with a groove corresponding to the convex tooth portion, so that the wiping cloth is clamped in the groove, and the friction and clamping force of the wiping cloth are increased by the concave and convex clamping method.

[0017] In some embodiments, the convex tooth portion is in an eccentric cone shape, and the guide plate is provided with a locking tooth facing the cloth receiving groove between two adjacent convex tooth portions.

[0018] In some embodiments, the driving mechanism includes a driving gear shaft rotatably mounted on the wiping body, and the support arm is correspondingly provided with an engaging rack engaged with the driving gear shaft; the cloth clamping mechanism is switched between the expanded state and the retracted cloth clamping state by rotating the driving gear shaft.

[0019] In some embodiments, the clamping structure also includes a holding mechanism that keeps the cloth clamping claw in a cloth clamping state when the cloth is clamped or in wiping use; the holding mechanism includes a holding spring arranged on the inner side of the cloth clamping claw, and the holding spring always provides an inward pulling force to the cloth clamping claw; or, the wiping body is connected to a hand-held rod, and the holding mechanism includes a fastener connected to the hand-held rod and a fastener platform connected to the driving mechanism.

[0020] In some embodiments, a twisted rod is installed in the hand-held rod, the twisted rod is connected to the driving gear shaft of the driving mechanism, and the twisted rod is connected to the driving gear shaft through an inner cross hinge shaft; the fastener is arranged at the lower end of the hand-held rod, and the buckle platform is arranged on the twisted rod. In this scheme, the rotation of the twisted rod is driven by the up and down movement of the hand-held rod, thereby realizing the rotation of the driving gear shaft; when the hand-held rod moves downward, the cloth clamping mechanism is switched to the retracted cloth clamping state, and the fastener at this time will be buckled with the buckle platform to form a certain self-locking.

[0021] In some embodiments, a guide buckle is provided on the wiping body, and a guide buckle groove that slides with the guide buckle is provided on the support arm; the wiping body includes an upper cover and a lower cover that are buckled with each other, and the upper cover and the lower cover are spliced ​​to form the cloth receiving groove; the guide buckle is provided on the upper cover, the guide plate is provided on the lower cover, and the wiping surface is located on one side of the bottom end of the lower cover.

[0022] In some embodiments, the hand-held rod is sheathed with a guide sleeve, and the guide sleeve is hingedly mounted on the wiping body via a universal joint; the guide sleeve and the universal joint are provided with positioning protrusions for keeping the hand-held rod and the wiping body in a vertical state.

[0059] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0060] See also Figure 1 and Figure 4 In order to solve the technical problem, the present specification provides a wiping cloth clamping structure, which can be applied to commonly used flat mops, desktop wipers, window wipers, blackboard erasers and other wiping tools, and specifically includes a hand-held rod 1, a wiping body 2 and a driving mechanism. The wiping body 2 is connected to the hand-held rod 1, and the bottom of the wiping body 2 is a wiping surface 201, and the wiping surface 201 is directly in contact with the installed wiping cloth 5; the side end of the wiping body 2 is movably installed with a cloth clamping mechanism 4 that can be expanded or retracted to clamp the cloth, and the cloth clamping mechanism 4 is used to clamp the wiping cloth 5; the driving mechanism drives the cloth clamping mechanism 4 to retract and retract, so that the cloth clamping mechanism 4 can switch between the expanded state and the retracted cloth clamping state. When the cloth clamping mechanism 4 is in the expanded state, it is used to wait for the wiping cloth 5 to be clamped. During the process of switching the cloth clamping mechanism 4 from the expanded state to the retracted cloth clamping state, the cloth clamping mechanism 4 clamps and fixes the wiping cloth 5. In one example, the cloth clamping mechanism 4 is movably installed at the front and rear side ends of the wiping body 2.

[0061] The cloth clamping mechanism 4 includes a support arm 401 and a cloth clamping claw 402 connected to the support arm 401. The cloth clamping claw 402 can move toward the wiping surface 201 (the cloth clamping claw 402 moves toward the wiping surface 201 to contact and grab the wiping cloth 5). The cloth clamping claw 402 is configured to move toward the wiping surface 201 when the cloth clamping mechanism 4 is extended as a whole; wherein, as Fig.13 As shown, the cloth clamping claw 402 is connected to an elastic member, and the elastic member is configured to make the cloth clamping claw 402 always have a tendency to swing toward the side of the wiping surface 201. When the support arm 401 of the cloth clamping mechanism 4 drives the cloth clamping claw 402 to slide outward, the elastic member drives the cloth clamping claw 402 to be lower than the wiping surface 201 (the cloth clamping claw 402 always has a tendency to move toward the side of the wiping surface 201, so as to achieve the gripping of the wiping cloth 5). The elastic member can always maintain an appropriate gripping force with the wiping cloth, and can maintain a good gripping effect according to different surfaces and different thicknesses of wiping cloth.

[0062] It should be pointed out that in the present embodiment, the cloth clamping claw 402 is driven to move toward the wiping cloth by the equipped elastic member, and the cloth gripping force of the cloth clamping claw 402 can be determined by the elastic force of the elastic member. Taking the commonly used cloth clamping mop as an example, in order to improve the cloth gripping effect, the traditional ordinary cloth clamping mop needs to press down the mop rod with force by hand, which will make the contact friction between the mop head (i.e., the wiping body 2) and the wiping cloth too large, thereby causing the cloth clamping claw 402 to be unable to retract into the cloth clamping state (i.e., the cloth clamping claw 402 is also simultaneously pressed down to abut against the wiping cloth, resulting in a situation where it cannot be reset, and when the force pressing down the mop rod is lighter, the wiping cloth may also be unable to be gripped).

[0063] Among them, a guide plate 202 is provided on the back of the wiping surface 201; when the cloth clamping mechanism 4 is in the unfolded state, the cloth clamping mechanism 4 extends outward, and the cloth clamping claws 402 are unfolded outward and downward along the guide plate 202, and the cloth clamping claws 402 are lower than the wiping surface 201 at this time; when clamping the cloth, the wiping body 2 is abutted against the wiping cloth 5, and the driving mechanism controls the cloth clamping mechanism 4 to switch from the unfolded state to the retracted cloth clamping state, and the cloth clamping claws 402 drive the wiping cloth 5 to retract and reset inward along the guide plate 202, and the guide plate 202 is used to guide the wiping cloth 5 to enter the retracted cloth clamping state, and the retracted cloth clamping state is the state of normal cleaning use of the wiping cloth clamping structure.

[0064] In some preferred embodiments, Figure 5 and Figure 6 As shown, the guide plate 202 is an oblique guide plate, which is used to assist the cloth clamping claws 402 in guiding the wiping cloth 5 .

[0065] In another embodiment, if Fig.17 As shown, the guide plate 202 can also be a thin-lip guide plate. The thickness of the thin-lip guide plate is preferably such that it is not easy to interfere with the cloth clamping claw 402. It is usually a thin plate structure of 1-3 mm. When the cloth is clamped or wiped, the thin-lip guide plate protrudes outward from the outer end of the cloth clamping claw 402 (combined with Fig.17 , the thin-lip guide plate is protruding from the cloth clamping claw 402 in the retracted cloth clamping state). Of course, in other examples, when the cloth is clamped or wiped, the cloth clamping claw 402 can also be flush with the thin-lip guide plate.

[0066] like Figure 4 As shown, the included angle between the obliquely arranged guide plate 202 and the wiping surface 201 is an acute angle.

[0067] It should be noted that the cloth clamping mechanism 4 is slidably mounted on the side of the wiping body 2 away from the wiping surface 201 (the cloth clamping claw 402 in the retracted cloth clamping state is higher than the wiping surface 201). Figure 4 and Figure 5As shown, a cloth clamping groove 3 is provided on the wiping body 2, and the height of the cloth clamping groove 3 is higher than the wiping surface 201; the guide plate 202 extends to the cloth clamping groove 3, and the cloth clamping mechanism 4 is slidably installed in the cloth clamping groove 3. When the cloth clamping mechanism 4 is in the retracted cloth clamping state, its cloth clamping claw 402 is retracted in the cloth clamping groove 3. Fig.16 That is, it is in the actual reference diagram of the cloth-clamping state, where the cloth-clamping mechanism 4 clamps the wiping cloth 5 into the cloth-clamping accommodating groove 3. At this time, the cloth-clamping mechanism 4 is retracted into the cloth-clamping accommodating groove 3, and the cloth-clamping claws 402 that clamp the wiping cloth 5 are also placed in the cloth-clamping accommodating groove 3. The cloth-clamping mechanism 4 can make the wiping cloth 5 completely clamp and wrap the wiping surface 201 in the front-to-back direction, thereby achieving a good wiping effect and avoiding the phenomenon in the prior art that the cloth-clamping claws are flush with the wiping surface, resulting in the cloth-clamping claws being exposed during wiping and causing wear of the cloth-clamping claws.

[0068] The guide plate 202 forms a cloth clamping path when clamping the wiping cloth 5, and guides the cloth clamping claw 402 to clamp the wiping cloth 5 into the cloth clamping accommodating groove 3 (so that the outer part of the wiping cloth 5 is folded and enters the cloth clamping accommodating groove 3); Fig.15 As shown in the figure, a real reference diagram is given in which the cloth clamping mechanism 4 on the wiping body 2 clamps the wiping cloth 5 into the cloth clamping accommodating groove 3. The wiping cloth 5 (the wiping cloth 5 on the front and back sides in the figure) is partially automatically "stuffed" into the cloth clamping groove 3 through the cloth clamping mechanism 4, so as to achieve the purpose of automatically clamping the wiping cloth 5, and the wiping cloth is convenient to replace; there is no need to manually install the wiping cloth 5 on the wiping body 2, so as to avoid hand contact with the wiping cloth 5.

[0069] The wiping cloth 5 in the embodiment of this specification is made of non-woven fabric (it can also be disposable items such as wet wipes and paper towels). The actual wiping effect of the actual sample product using the wiping cloth clamping structure based on the above principle is good, the cloth clamping is accurate and reliable, and the switching of the cloth clamping is convenient.

[0070] In one example, the cloth clamping claw 402 of the embodiment of the present specification is hingedly installed on one side of the support arm 401 and can be rotated up and down through a hinge shaft, and the cloth clamping claw 402 can be flipped and moved closer to the side of the wiping cloth 5; the cloth clamping claw 402 in the expanded state contacts the wiping cloth 5, and when the expanded state is switched to the retracted cloth clamping state, the cloth clamping claw 402 clamps the wiping cloth 5 into the cloth clamping accommodating groove 3.

[0071] It should be pointed out that the cloth clamping claw 402 of the embodiment of the present specification is different from the prior art. It can be driven by the support arm 401 to perform telescopic movement in the cloth clamping groove 3, and can also be flipped and swung toward the wiping surface 201 relative to the support arm 401, so that the cloth clamping claw 402 can abut against the wiping cloth 5 to grasp the wiping cloth 5, and the flipping and swinging of the cloth clamping claw 402 is achieved by an elastic member.

[0072] Combined with the guide plate 202, a cloth clamping path is formed, and the wiping cloth 5 is finally clamped and positioned in the cloth clamping accommodating groove 3. The guide plate can keep the cloth clamping claw 402 in contact with the wiping cloth to prevent the cloth clamping claw 402 from separating from the wiping cloth during the contraction process. The inclined guide plate 202 is also conducive to more stable cloth clamping. The cloth clamping claw 402 in the expanded state has a large expansion stroke, which is convenient for grabbing the wiping cloth 5.

[0073] When the cloth clamping mechanism 4 clamps the cloth, Fig.14 As shown, the wiping surface 201 of the wiping body 2 is placed on a new wiping cloth 5, and the cloth clamping claws 402 in the unfolded state (waiting for cloth clamping) abut against the wiping cloth 5; during the process of the cloth clamping mechanism 4 switching from the unfolded state to the retracted cloth clamping state, the support arm 401 guides the cloth clamping claws 402 to retract and reset, and the cloth clamping claws 402 correspond to the wiping cloth 5 from the plane where the wiping surface 201 is located, and finally clamp it into the cloth clamping groove 3 under the guidance of the guide plate 202. Fig.14 As shown, at this time, the cloth clamping mechanism 4 is in a retracted cloth clamping state, and the cloth clamping claws 402 are retracted into the cloth clamping accommodating groove 3.

[0074] In some embodiments, when the cloth clamping mechanism 4 is in the unfolded state, the height of the cloth clamping claw 402 is lower than the wiping surface 201; Fig.14 As shown, after ensuring that the entire wiping body 2 is placed on the wiping cloth 5 , the cloth clamping claws 402 can contact and clamp the wiping cloth 5 .

[0075] It should be pointed out that when the cloth clamping claw 402 of the embodiment of the present specification extends outward from the cloth clamping groove 3, it can simultaneously realize its downward movement (specifically, hinged swing in the embodiment of the present specification), so that the cloth clamping claw 402 can abut against the plane where the wiping surface 201 is located (placing the wiping surface 201 on the wiping cloth 5 can make the cloth clamping claw 402 move and abut against the wiping cloth 5).

[0076] In one example, if Figure 8 As shown, the elastic member includes a torsion spring 6 installed at the hinge of the cloth clamping claw 402 , one end of the torsion spring 6 is installed on the support arm 401 , and the other end is placed on the cloth clamping claw 402 .

[0077] In some embodiments, Figure 1 and Fig.10 As shown, the cloth clamping claw 402 includes convex teeth 403 that are equally spaced and staggered, and the staggered convex teeth 403 are configured to firmly grasp the wiping cloth 5 , thereby effectively increasing the grasping area of ​​the wiping cloth 5 .

[0078] In some preferred embodiments, see Figure 5 The guide plate 202 is provided with a groove 207 corresponding to the convex tooth portion 403, so that the wiping cloth 5 is clamped in the groove 207, and the friction and clamping force of the wiping cloth 5 are increased by the concave and convex clamping method.

[0079] Fig.13 and Fig.14 That is, it is a schematic diagram of the cloth clamping mechanism 4 on the wiping body 2 being in an unfolded state.

[0080] like Fig.15 As shown, the wiping cloth 5 is larger than the length and width of the wiping body 2 as a whole (the wiping cloth 5 in the figure is for reference only, and its length and width can be designed and optimized separately).

[0081] like Fig.10 As shown, in a preferred embodiment, the convex tooth portion 403 is in an eccentric cone shape, so that the convex tooth portion 403 is staggered on the cloth clamping claw 402. The convex tooth portion 403 of the embodiment of this specification is different from the existing tooth structure that simply adopts a linear array layout. The eccentrically arranged convex tooth portion 403 is staggered on the cloth clamping claw 402, which helps the convex tooth portion 403 to better clamp the wiping cloth 5, ensuring that the cloth is clamped accurately and reliably each time the wiping cloth 5 is replaced.

[0082] In some preferred embodiments, Figure 5 As shown, the guide plate 202 is provided with a clamping tooth 203 facing the cloth clamping accommodating groove 3 between two adjacent convex tooth portions 403 . The clamping tooth 203 is higher than the guide plate 202 , and plays a role in assisting in clamping the wiping cloth 5 .

[0083] like Figure 5 As shown, in one example, the engaging teeth 203 are sawtooth portions.

[0084] In some embodiments, Figure 4 and Fig.13 As shown, the driving mechanism includes a driving gear shaft 7 rotatably mounted on the wiping body 2. Specifically, the driving gear shaft 7 of the embodiment of this specification is rotatably buckled on the wiping body 2; Fig. 9 As shown, the support arm 401 is correspondingly provided with an engaging rack 404 engaged with the driving gear shaft 7; the hand-held rod 1 is transmission-connected with the driving gear shaft 7, and the driving gear shaft 7 is driven to rotate by the hand-held rod 1 to realize the switching of the cloth clamping mechanism 4 between the unfolded state and the retracted reset state.

[0085] In some embodiments, the clamping structure further includes a holding mechanism for keeping the cloth clamping claws 402 in a cloth clamping state after the cloth is clamped or during wiping use.

[0086] In one example, the holding mechanism includes a holding spring disposed inside the cloth clamping claw 402 , and the holding spring always provides an inward pulling force to the cloth clamping claw 402 .

[0087] In another example, Figure 4 As shown, the holding mechanism includes a fastener 9 connected to the handle bar 1 and a fastener platform 10 connected to the driving mechanism.

[0088] It should be pointed out that the embodiments of this specification do not limit the specific structure of how the hand-held rod 1 realizes the rotation of the driving gear shaft 7. The hand-held rod 1 can be rotated circumferentially (clockwise or counterclockwise) to control the rotation of the driving gear shaft 7 to realize the state switching of the cloth clamping mechanism 4; the hand-held rod 1 can also be pressed axially (the vertical movement is switched to the rotational movement of the driving gear shaft 7 through the twisted rod mechanism) to control the rotation of the driving gear shaft 7 to realize the state switching of the cloth clamping mechanism 4; Figure 4 As shown, in one example, a twisted rod transmission connection is used to realize power transmission, which will not be described in detail in the embodiments of this specification. When replacing the dirty wiping cloth 5, the driving gear shaft 7 is driven to rotate by the hand-held rod 1, so that the cloth clamping mechanism 4 is switched to the unfolded state, and the dirty wiping cloth 5 can be removed (the dirty wiping cloth 5 can be stepped on to ensure that it is completely separated from the wiping body 2).

[0089] In one example, if Figure 4 As shown, a twisted rod is installed in the hand-held rod 1, and the twisted rod is transmission-connected to the driving gear shaft 7 of the driving mechanism. A fastener 9 is arranged at the lower end of the hand-held rod 1, and a fastening platform 10 is arranged on the twisted rod.

[0090] In some embodiments, see Fig.12 A guide buckle 204 is provided on the wiping body 2, and a guide buckle groove 405 that slides with the guide buckle 204 is provided on the support arm 401; through the sliding cooperation between the guide buckle 204 and the guide buckle groove 405, the support arm 401 is slidably positioned in the cloth clamping groove 3 of the wiping body 2.

[0091] Specific, combined Figure 1 , Figure 5 , Figure 6 and Figure 7 The wiping body 2 includes an upper cover 205 and a lower cover 206 that are buckled together, and the upper cover 205 and the lower cover 206 are spliced ​​to form a cloth receiving groove 3; the guide buckle 204 is arranged on the upper cover 205, the guide plate 202 is arranged on the lower cover 206, and the wiping surface 201 is located at one side of the bottom end of the lower cover 206. A decorative bottom plate is installed at the bottom of the lower cover 206 to form the wiping surface 201.

[0092] It should be pointed out that the wiping surface 201 of the present application has a flat structure, which makes the structure of the entire wiping body 2 simple and beautiful.

[0093] like Figure 4 and Figure 6 As shown, the cross section of the lower cover 206 is an isosceles trapezoid as a whole (the hypotenuse thereof is the guide plate 202 structure).

[0094] In some embodiments, Figure 1 and Figure 4 As shown, the hand-held rod 1 is covered with a guide sleeve 8, and the guide sleeve 8 is hingedly mounted on the wiping body 2 through a universal joint 801, so that the hand-held rod 1 can rotate forward and backward or left and right, which will not be specifically described in the embodiments of this specification. Figure 1 , Figure 3 and Fig.13 As shown, the guide sleeve 8 and the universal joint 801 are provided with positioning protrusions for keeping the hand-held rod 1 and the wiping body 2 in a vertical state, and the wiping cloth can be replaced in the vertical state.

[0095] The same and similar parts between the various embodiments in this specification can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0096] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
