Description

Technical Field

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

[0002] Flat mops are commonly used household cleaning tools, mainly including a mop rod and a mop head for wiping the floor. A wiping cloth is installed at the bottom of the mop head, 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 mop head. 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. 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

[0008] 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 outwardly and synchronously unfolded along the guide plate; when clamping the cloth, the wiping body is abutted against the wiping cloth, and the cloth clamping mechanism switches 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 to reset. The guide plate and the cloth clamping claw structure that can move toward one side of the wiping surface realize automatic "grabbing" of the wiping cloth, and the guide plate can keep the cloth clamping claws and the wiping cloth in contact to avoid separation from the wiping object during the contraction of the cloth clamping claws. At the same time, the guide plate guides the cloth clamping claws to leave the bottom surface (the bottom surface contacted by the wiping body when clamping the cloth), so that the wiping object completely covers the bottom surface of the wiping body.

[0009] In some embodiments, the cloth clamping structure further includes a retaining mechanism for keeping the cloth clamping claw in the cloth clamping state after the cloth clamping is completed or when the cloth is used for wiping. The retaining mechanism may be a retaining spring or a lock.

[0011] In some embodiments, the cloth clamping structure includes a driving mechanism, and the driving mechanism drives the cloth clamping mechanism to extend and retract, and the driving mechanism drives the cloth clamping mechanism to extend and retract, so that the cloth clamping mechanism switches between an extended state and a retracted cloth clamping state.

[0012] In some embodiments, the cloth clamping mechanism further includes a pressing mechanism for keeping the cloth clamping claw pressed downward when clamping the cloth, and the pressing mechanism is an elastic member or a top block disposed between the wiping body and the cloth clamping claw, so as to better keep the cloth clamping claw and the wiping cloth in contact and avoid separation. The top block is disposed on the inner side of the wiping body, and can push the cloth clamping claw downward to move toward the wiping surface when the cloth clamping claw is extended outward.

[0013] In some embodiments, 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. Taking a flat mop as an example, the hand-held rod is the mop rod of the flat mop, and the hand-held rod realizes the movement of the driving mechanism through its up and down reciprocating motion, thereby controlling the extension and retraction of the cloth clamping claws. When the hand-held rod moves downward, its fastener is fastened to the fastener platform to form a holding mechanism, which has a certain self-locking property.

[0014] In some embodiments, the guide plate is an oblique guide plate.

[0023] In some embodiments, the guide plate can be flipped and hinged on the side end of the wiping body. When switched to the unfolded state, the cloth clamping claw extends outward, pushing the guide plate to flip outward and abut against the external wiping cloth; when switched to the retracted cloth clamping state to clamp the cloth, the cloth clamping claw drives the wiping cloth to shrink inward along the guide plate and reset, and the guide plate flips upward and covers the side end of the wiping body. Therefore, the guide plate flips the wiping cloth upward and covers the side end of the wiping body.

[0024] In some embodiments, when clamping cloth, the guide plate at least partially covers the cloth clamping claw; and / or, a first reset elastic member is installed between the guide plate and the cloth clamping claw, and the first reset elastic member is used to pull the guide plate when clamping cloth so that it flips and abuts against the side end of the wiping body; and / or, the first reset elastic member is a tension spring.

[0025] In some embodiments, the guide plate is provided with guide plate convex teeth at intervals for increasing the clamping force of the wiping cloth.

[0026] In some embodiments, when clamping cloth, the guide plate at least partially covers the cloth clamping claw; the cloth clamping claw is transmission-connected to the guide plate via a connecting rod mechanism; the connecting rod mechanism is used to pull the guide plate to flip it over and abut against the side end of the wiping body when clamping cloth.

[0037] (III) Beneficial effects

[0038] The wiping cloth clamping structure provided by the utility model has the following advantages compared with the prior art:

[0039] The cloth clamping mechanism of the utility model can extend or retract the side end of the wiping body, and its cloth clamping claw can move relatively toward the wiping surface, so that after the wiping surface of the wiping body is placed on the external wiping cloth, its cloth clamping claw can contact the wiping cloth, and when the cloth clamping claw of the cloth clamping mechanism retracts to clamp the cloth, the wiping cloth is finally clamped into the cloth clamping accommodating groove under the guidance of the guide plate, and the cloth clamping accommodating groove is higher than the wiping surface, so that people do not have to worry about bumping against the cloth clamping claw during daily use;

[0040] The cloth clamping claw of the utility model is hingedly mounted on the support arm of the cloth clamping mechanism, so that the cloth clamping claw can be turned downward to "grasp" the wiping cloth; preferably, the elastic torsion spring provided at the hinged position ensures that the cloth clamping claw can clamp the wiping cloth; the elastic member can adaptively adjust the swing amplitude of the cloth clamping claw to maintain a good wiping cloth grabbing effect;

[0041] The cloth clamping claw of the utility model comprises convex teeth arranged at equal intervals and in a staggered distribution, and the convex teeth are eccentrically arranged, so as to effectively grasp the wiping cloth;

[0042] The cloth clamping mechanism of the utility model realizes the retraction or extension of the support arm through the movement of the driving mechanism, which can be specifically realized by the rotation or up and down sliding of the driving mechanism.

[0087] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0088] 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 cleaning tools such as flat mops, window cleaners, and desktop erasers. The clamping structure specifically includes a wiping body 2, the bottom of which is a wiping surface 201, and the wiping surface 201 is directly in contact with the installed wiping cloth 5; a clamping mechanism 4 that can be unfolded or retracted is movably installed on the side of the wiping body 2, and the clamping mechanism 4 is used to clamp the wiping cloth 5. In this embodiment, the clamping mechanism 4 is movably arranged on both sides of the wiping body 2. When the clamping mechanism 4 is in the unfolded state, it is used to wait for the wiping cloth 5 to be clamped. When the clamping mechanism 4 switches from the unfolded state to the retracted clamping state, the clamping mechanism 4 clamps and fixes the wiping cloth 5. The wiping cloth clamping structure can be applied to wiping tools, which can be flat mops, window cleaners, desktop erasers, or blackboard erasers. When the wiping cloth clamping structure is applied to a flat mop, its wiping body 2 is the mop head of the flat mop.

[0089] The cloth clamping mechanism 4 includes a cloth clamping claw 402, which 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 synchronously during the overall extension of the cloth clamping mechanism 4.

[0090] The back of the wiping surface 201 is provided with a guide plate 202; when the cloth clamping mechanism 4 is in the unfolded state, the cloth clamping mechanism 4 extends outward, and the cloth clamping claw 402 is unfolded outward along the guide plate 202 (such as Fig.14As shown, specifically, it is unfolded downward toward one side of the wiping cloth 5), at this time, the cloth clamping claws 402 are lower than the wiping surface 201; when clamping the cloth, the wiping body 2 is abutted against the wiping cloth 5, and the cloth clamping mechanism 4 is switched from the unfolded state to the retracted cloth clamping state, and the cloth clamping claws 402 drive the wiping cloth 5 to retract inward along the guide plate 202 and reset, 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 in which the wiping tool is normally used for cleaning (when the wiping tool is a flat mop, it is the state in which the retracted cloth clamping state is normally used for mopping and cleaning).

[0091] In some embodiments, the cloth clamping structure further includes a driving mechanism, which drives the cloth clamping mechanism 4 to extend and retract, so that the cloth clamping mechanism 4 can be switched between an extended state and a retracted cloth clamping state.

[0092] 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 .

[0093] 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, 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 protrudes outward from the cloth clamping claw 402 in the retracted cloth clamping state).

[0094] like Figure 4 As shown, the included angle between the obliquely arranged guide plate 202 and the wiping surface 201 is an acute angle.

[0095] 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 5 As 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.16That is, it is in the retracted cloth clamping state, and the cloth clamping mechanism 4 clamps the wiping cloth 5 into the cloth clamping accommodating groove 3. The actual reference diagram shows that the cloth clamping mechanism 4 is in the retracted cloth clamping state, and the cloth clamping claws 402 that clamp the wiping cloth 5 are also placed in the cloth clamping groove 3. The cloth clamping mechanism 4 can make the wiping cloth 5 completely clamp and wrap the wiping surface 201 in the front and back directions, and the cleaning effect is good, 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 when mopping the floor, resulting in the wear of the cloth clamping claws.

[0096] 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, taking a flat mop as an example, the figure shows a real reference diagram in which the cloth clamping mechanism 4 on the wiping body 2 clamps the wiping cloth 5 into the cloth clamping accommodating groove 3. In the figure, the wiping cloth 5 on the front and rear sides is automatically "stuffed" into the cloth clamping accommodating groove 3 through the cloth clamping mechanism 4, so as to achieve the purpose of automatically clamping the wiping cloth 5 and facilitate the replacement of the wiping cloth; 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.

[0097] The wiping cloth 5 of the embodiment of this specification is made of non-woven fabric. Taking the cloth-clamped flat mop as an example, the actual mopping effect of the actual sample product of the cloth-clamped flat mop using the above principle is good, the clamping cloth is accurate and reliable, and the clamping cloth is convenient to switch. Of course, the wiping cloth 5 can also be a disposable product such as a paper towel or a wet wipe.

[0098] In some embodiments, the cloth clamping mechanism further includes a pressing mechanism for keeping the cloth clamping claw 402 pressed downward when clamping the cloth, and the pressing mechanism is an elastic member or a top block arranged between the wiping body 2 and the cloth clamping claw 402. When the pressing mechanism is a top block, the top block is arranged on the inner side of the wiping body 2, and when the cloth clamping claw 402 is expanded outward, the cloth clamping claw 402 can be pushed downward to move toward the side of the wiping surface 2 (when the cloth is retracted, the top block does not press down the cloth clamping claw 402, which can be achieved by setting an avoidance groove on one side of the cloth clamping claw 402).

[0099] The cloth clamping mechanism 4 further includes a support arm 401, and a cloth clamping claw 402 is hingedly mounted on the support arm 401 so as to rotate up and down. In one example, the cloth clamping claw 402 of the embodiment of the present specification can be hingedly mounted on one side of the support arm 401 by a hinge shaft so as to rotate up and down, and the cloth clamping claw 402 can be turned and moved closer to one side of the wiping cloth 5; the cloth clamping claw 402 in the unfolded state contacts the wiping cloth 5, and when the unfolded 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. When the cloth clamping mechanism 4 is in the unfolded state, the outer end of the cloth clamping claw 402 (for grabbing the wiping cloth) is lower than the wiping surface 201; when the cloth clamping mechanism 4 is in the retracted cloth clamping state, the cloth clamping claw 402 clamping the wiping cloth 5 is higher than the wiping surface 201, and the cloth clamping mechanism enables the wiping cloth to completely wrap the wiping surface 201 in the front-to-back direction, and the mopping effect is good.

[0100] 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 accommodating groove 3, and can also be flipped and swung relative to the support arm 401 toward the wiping surface 201, so that the cloth clamping claw 402 can abut against the wiping cloth 5 to grasp the wiping cloth 5, and then combined with the guide plate 202 to form a cloth clamping path, the wiping cloth 5 is finally clamped and positioned in the cloth clamping groove 3, and the operation is simple. The inclined guide plate 202 is also conducive to more stable cloth clamping. The cloth clamping claw 402 in the unfolded state has a large unfolding stroke, which is convenient for grasping the wiping cloth 5.

[0101] When the cloth clamping mechanism 4 clamps the cloth, Fig.14 As shown, taking a flat mop as an example, 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 correspondingly move 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.

[0102] 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 .

[0103] 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).

[0104] In some embodiments, the cloth clamping claw 402 is connected to an elastic member, and the elastic member serves as a downward pressing mechanism. The elastic member is configured to enable the cloth clamping claw 402 to 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 and expand 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, thereby achieving the gripping of the wiping cloth 5).

[0105] 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. As an elastic member, the torsion spring 6 can adaptively adjust the swing amplitude of the cloth clamping claw to maintain a good wiping cloth grabbing effect.

[0106] 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 .

[0107] 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.

[0108] 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.

[0109] 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).

[0110] like Fig.10As 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.

[0111] 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 .

[0112] like Figure 5 As shown, in one example, the engaging teeth 203 are sawtooth portions.

[0113] In some embodiments, Fig.30 As shown, a through groove 209 is correspondingly provided on one side of the guide plate 202 at this time.

[0114] In some embodiments, Figure 4 and Fig.13 As shown, the driving mechanism includes a driving member rotatably mounted on the wiping body 2, and the cloth clamping claw 402 is driven to expand outward or retract inward by the rotation of the driving member. Specifically, the driving member of the embodiment of this specification is a driving gear shaft 7, and the driving gear shaft 7 is rotatably mounted 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; taking the flat mop as an example, its wiping body 2 is the mop head of the flat mop, and the hand-held rod 1 is the mop rod of the flat mop. The hand-held rod 1 is connected to the driving gear shaft 7 by transmission, 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.

[0115] It should be pointed out that the embodiments of this specification do not limit the specific structure of how to realize the rotation of the driving gear shaft 7. Taking a flat mop as an example, the rotation of the driving gear shaft 7 can be controlled by circumferentially rotating (clockwise or counterclockwise) the hand-held rod 1 of the flat mop to realize the state switching of the cloth clamping mechanism 4; the rotation of the driving gear shaft 7 can also be controlled by axially pressing the hand-held rod 1 of the flat mop (switching the vertical movement to the rotational movement of the driving gear shaft 7 through the twisted rod mechanism) to realize the state switching of the cloth clamping mechanism 4; Figure 4As 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 mop head 2).

[0116] 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 mop head 2.

[0117] Specific, combined Figure 1 , Figure 5 , Figure 6 and Figure 7 Taking a flat mop as an example, the wiping body 2 (i.e., the mop head of the flat mop) includes an upper cover 205 and a lower cover 206 that are interlocked, 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.

[0118] 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.

[0119] 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).

[0120] In some embodiments, the cloth clamping structure further includes a retaining mechanism that enables the cloth clamping claws 402 to maintain the cloth clamping state when the cloth is clamped or when used for wiping. The retaining mechanism may be a retaining spring or a lock.

[0121] In one example, the holding mechanism is 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 .

[0122] In another example, the holding mechanism is realized by a buckle mechanism; the wiping body 2 is connected to the hand-held rod 1, and the holding mechanism includes a buckle 15 connected to the hand-held rod 1 and a buckle platform 16 connected to the driving mechanism. A twisted rod is rotatably installed in the hand-held rod 1, and the twisted rod is connected to the driving mechanism through an inner cross hinge shaft, and the buckle platform 16 is set on the twisted rod.

[0123] Specifically, if Figure 4, Fig. 20 As shown, the driving mechanism at this time is a rotatable driving member, specifically a driving gear shaft 7, and the extension and retraction of the entire cloth clamping mechanism 4 is achieved through a gear rack structure.

[0124] In some embodiments, Figure 18-Figure 29 As shown, the guide plate 202 can be flipped and hingedly installed on the side end of the wiping body 2. When switched to the unfolded state, the cloth clamping claws 402 extend outward, pushing the guide plate 202 to flip outward and abut against the external wiping cloth 5; when switched to the retracted cloth clamping state for clamping the cloth, the cloth clamping claws 402 drive the wiping cloth 5 to retract inward along the guide plate 202 and reset, and the guide plate 202 flips upward and covers the side end of the wiping body 2.

[0125] In some embodiments, Fig.19 or Fig.23 As shown, when clamping cloth, the guide plate 202 at least partially covers the cloth clamping claw 402; Fig.21 As shown, a first reset elastic member 9 is installed between the guide plate 202 and the cloth clamping claw 402, and the first reset elastic member 9 is used to pull the guide plate 202 to flip it and abut against the side end of the wiping body 2 when clamping the cloth; and / or, the first reset elastic member 9 is a tension spring.

[0126] In some embodiments, Fig.21 , Fig. 27 and Fig.28 As shown, guide plate convex teeth 208 are arranged at intervals on the guide plate 202 for increasing the clamping force of the wiping cloth 5 .

[0127] In another embodiment, the cloth clamping claw 402 is transmission-connected to the guide plate 202 via a connecting rod mechanism, and similarly, the guide plate 202 at least partially covers the cloth clamping claw 402 when clamping cloth; the connecting rod mechanism is used to pull the guide plate 202 when clamping cloth to flip it over and abut against the side end of the wiping body 2.

[0128] like Figure 25-28 As shown, the force that pushes the guide plate 202 to rotate comes from the cloth clamping claw 402. When the cloth clamping claw 402 retracts and resets, the guide plate 202 is driven to flip through the equipped connecting rod mechanism so that it covers the side end of the wiping body 2; Fig.23 In the embodiment, the guide plate 202 completely covers the cloth clamping claws 402.

[0129] In some embodiments, Figure 27-Figure 29 As shown, the connecting rod mechanism includes a first swing rod 11 hinged to the cloth clamping claw 402 and a second swing rod 12 hinged to the guide plate 202 . The first swing rod 11 is formed with a slide groove 1101 , and a hinge pin of the second swing rod 12 is slidably installed in the slide groove 1101 .

[0130] In some embodiments, the guide plate 202 is rotatably mounted on the side end of the wiping body 2 via a hinge shaft, and a return torsion spring is installed at the hinge of the guide plate 202, which always provides a thrust for the guide plate 202 to flip upward.

[0131] In some embodiments, Figure 22-Figure 26 As shown, the driving mechanism includes a control rod 13 which can be slidably installed on the wiping body 2 up and down, and a support arm 401 is hingedly installed on the control rod 13, and the support arm 401 is hinged with the cloth clamping claw 402; by pressing down the control rod 13, the support arm 401 relatively pushes the cloth clamping claw 402 to expand outward, and pushes the guide plate 202 to flip outward and abut against the external wiping cloth 5.

[0132] In some embodiments, Fig.24 As shown, a second resetting elastic member 14 is installed inside the control rod 13. The second resetting elastic member 14 always provides an upward thrust to the control rod 13, so that the support arm 401 drives the cloth clamping claw 402 to retract inwardly; the second resetting elastic member 14 is a spring. In this solution, the second resetting elastic member 14 serves as a retaining mechanism, so that the support arm 401 can always drive the cloth clamping claw 402 to retract inwardly. Only by pressing the control rod 13 can the support arm 401 drive the cloth clamping claw 402 to expand and clamp the cloth (such as Fig. 22 shown).

[0133] In some embodiments, Figure 1 and Figure 4 As shown, the hand-held rod 1 is sheathed with a guide sleeve 8, and the guide sleeve 8 is hingedly mounted on the mop head 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.

[0134] Based on the same inventive concept, the embodiment of this specification also provides a wiping tool, including the wiping cloth clamping structure of any of the aforementioned embodiments, the wiping tool is a flat mop, including a hand-held rod 1 connected to a wiping body 2, and the hand-held rod 1 is a mop rod. It should be pointed out that the flat mop preferably uses the hand-held rod 1 to move up and down to drive the driving member to rotate (the hand-held rod 1 realizes the rotation of the driving gear shaft 7 through the twisted rod structure), thereby realizing the extension and retraction of the two cloth clamping claws 402. It can also be realized by a structure in which the support arm 401 drives the cloth clamping claws 402 to expand by pressing the control rod 13.

[0135] Based on the same inventive concept, the embodiment of this specification also provides a wiping tool, including the wiping cloth clamping structure of any of the above embodiments, and the wiping tool is a window cleaner. The window cleaner can also use the hand-held rod 1 to move up and down to ultimately drive the two cloth clamping claws 402 to extend and retract, or it can be achieved by pressing the control rod 13 to make the support arm 401 drive the cloth clamping claws 402 to expand.

[0136] Based on the same inventive concept, the embodiment of this specification also provides a wiping tool, including the wiping cloth clamping structure of any of the above embodiments, the wiping tool is a desktop eraser or a blackboard eraser, and may include a handle 10 installed on the wiping body 2. Figure 22-Figure 26 As shown, when the wiping tool is a desktop wiper, the two cloth clamping claws 402 can be controlled to expand by pressing the control rod 13, and the pressing force applied to the control rod 13 is removed to reset it, thereby driving the two cloth clamping claws 402 to reset and retract.

[0137] It should be pointed out that the desktop eraser or blackboard eraser is also suitable for driving the two cloth clamping claws 402 to expand or retract by combining the hand-held rod 1 with a twisted rod or other structures.

[0138] 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.

[0139] 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.
