[0006] The rotating component is driven by the hand lever and can rotate around its own circumference, allowing the rotating component to switch between an unlocked state and a locked state.

[0007] When the rotating component is in the unlocked state, the hand lever can rotate relative to the scraping head along the width direction of the scraping head to change the angle between the hand lever and the scraping head;

[0008] When the rotating assembly is in the locked state, the rotation of the hand lever along the width direction of the scraping head is restricted.

[0009] Beneficial effects: This utility model provides a scraping cleaning tool, which has a rotating component between the handle and the scraping head. The handle can rotate along the width of the scraping head to change the scraping angle of the scraping head. At the same time, the rotating component can be unlocked by rotating around its own circumference driven by the handle, so that the user can rotate the handle along the width of the scraping head at any time to adjust the scraping angle of the scraping head for user convenience.

[0010] In one optional embodiment, the rotating component has a first position and a second position, and when the rotating component rotates circumferentially in the first position and the second position, the unlocked state and the locked state of the rotating component can be switched.

[0019] In one optional embodiment, the rotating assembly includes a first rotating part and a second rotating part connected to each other, and the hand handle is rotatably connected to the scraping head through the first rotating part and the second rotating part;

[0020] The first rotating part is rotatably connected to the hand handle via a rotating shaft, so that the hand handle is rotatably disposed on the scraping head and can rotate relative to the scraping head about the axis of the rotating shaft.

[0021] The second rotating part is circumferentially rotatably connected to the scraping head and can rotate relative to the scraping head along its own circumference, so that when the hand handle rotates along its own circumference, it can drive the first rotating part and the second rotating part to rotate synchronously in the circumferential direction, thereby driving the rotating shaft to rotate in the circumferential direction, so that the rotating assembly rotates to the unlocked state or the locked state.

[0022] When the rotating assembly is in the unlocked state, the axial direction of the rotating shaft is parallel to the length direction of the scraping head;

[0023] When the rotating assembly is in the locked state, the axial direction of the rotating shaft is not parallel to the length direction of the scraping head.

[0024] Beneficial effects: The handheld lever and the scraping head are connected by the first and second rotating parts that are interconnected. The rotating shaft of the first rotating part is rotatably connected to the handheld lever, so that the handheld lever can rotate closer to or away from the scraping head. The second rotating part is circumferentially connected to the scraping head, so that the handheld lever can rotate relative to the scraping head in its own circumference.

[0025] In one optional embodiment, the scraping head is provided with a mounting groove, and the second rotating part is inserted into the mounting groove so that the second rotating part is circumferentially rotatably connected to the scraping head.

[0026] Beneficial effects: The scraper head is provided with a mounting groove so that the second rotating part can be inserted and matched with the mounting groove, so that the second rotating part and the scraper head can be circumferentially rotated and connected.

[0031] Beneficial effect: A one-way limiting mechanism is provided between the second rotating part and the mounting groove to control the second rotating part to rotate only in one direction relative to the scraping head, so as to avoid excessive wear between the second rotating part and the inner wall of the mounting groove when it is driven to rotate.

[0032] In one optional embodiment, the one-way limiting mechanism includes at least one one-way groove and at least one limiting ratchet that cooperate with each other. One of the at least one one-way groove and at least one limiting ratchet is provided on the outer wall of the second rotating part, and the other is provided on the inner wall of the mounting groove.

[0033] And / or, the handheld lever is configured as a multi-segment lever, with adjacent segments connected by threads; the direction in which the second rotating part can rotate unidirectionally relative to the scraping head is the same as the direction of the threaded connection between the levers.

[0034] Beneficial effects: The unidirectional rotational engagement between the second rotating part and the mounting groove is achieved through a unidirectional rotational engagement structure using a one-way groove and a limiting ratchet. The structure is simple and the connection is reliable. The direction in which the second rotating part can rotate relative to the scraping head is limited to the same direction as the threaded connection between the rods, thus preventing the multiple sections of the rod from loosening when the second rotating part rotates with the hand handle, ensuring the structural stability of the scraping cleaning tool.

[0035] In one alternative embodiment, a first limiting component is provided between the rotating assembly and the handheld lever, the first limiting component limiting the maximum angle of rotation of the handheld lever relative to the scraping head.

[0036] Beneficial effects: The first limiting component restricts the maximum angle of rotation of the handle as it approaches or moves away from the scraper head, preventing excessive rotation of the handle relative to the scraper head and thus affecting the water-pushing effect. Simultaneously, the rotation angle between the scraper head and the handle is limited, ensuring the structural stability of the scraping cleaning tool.

[0037] In one optional embodiment, the first limiting component includes a slider and a groove that cooperate with each other. One of the slider and the groove is disposed on the rotating component, and the other is disposed on the hand handle. When the slider abuts against the end of the groove, it limits the maximum angle of rotation of the hand handle relative to the scraping head.

[0038] Beneficial effects: The sliding cooperation between the slider and the groove limits the maximum angle of rotation of the hand handle when it moves closer to or away from the scraping head. The structure is simple and the cooperation is stable.

[0039] In one alternative embodiment, a second limiting component is provided between the rotating component and the handheld lever, the second limiting component restricting the rotation of the handheld lever relative to the scraping head, so as to fix the position of the handheld lever relative to the scraping head.

[0040] Beneficial effects: The second limiting component restricts the positioning of the hand handle as it approaches or moves away from the rotating position of the scraping head, thereby fixing the position of the hand handle and ensuring the stability of the scraping cleaning tool.

[0041] In one optional embodiment, the second limiting component includes a locking block and a plurality of spaced-apart positioning holes, one of which is located on the rotating component and the other is located on the hand handle.

[0042] After the handheld lever rotates relative to the rotating assembly, the locking block can engage with one of the positioning holes to fix the position of the handheld lever relative to the scraping head.

[0043] Beneficial effects: By using the locking block and multiple spaced positioning holes to engage, the endpoint position of the handheld lever's rotation as it approaches or moves away from the scraping head is limited. The structure is simple and the engagement is stable.

[0044] In one optional embodiment, when the scraping cleaning tool is provided with a first limiting component and a second limiting component, and the rotating component includes a first rotating part and a second rotating part, the first limiting component and the second limiting component are disposed between the first rotating part and the handle.

[0045] Beneficial effect: The first limiting component and the second limiting component are located between the first rotating part and the hand handle to achieve a stable connection between the first limiting component and the second limiting component between the rotating part and the hand handle.

[0046] In one optional embodiment, the first rotating part has two mounting surfaces facing away from each other, and the hand handle has two mounting plates oppositely arranged at one end near the first rotating part, forming a mounting space between the two mounting plates. The first rotating part is disposed in the mounting space, and the first limiting component and the second limiting component are disposed between the mounting surfaces and the mounting plates.

[0047] Beneficial effect: The mounting space formed between the two mounting plates on the handgrip provides a mounting position for the first rotating part, so that the first rotating part can be embedded between the two mounting plates to form a stable installation.

[0048] In an optional embodiment, when the first limiting component includes a slider and a groove, the slider is disposed on the mounting surface and the groove is disposed on the mounting plate; the groove is constructed as an arc-shaped structure, and the center of the arc-shaped structure is coaxially arranged with the rotation axis connecting the first rotating part and the hand handle.

[0049] And / or, when the second limiting component includes a locking block and a positioning hole, the locking block is disposed on the mounting surface and the positioning hole is disposed on the mounting plate; the plurality of positioning holes are distributed in an arc shape, and the center of the arc is coaxially disposed with the rotation axis connecting the first rotating part and the hand handle.

[0050] Beneficial effects: The slide groove is constructed in an arc shape to accommodate the rotation of the handheld lever with the mounting plate relative to the first rotating part, preventing positional interference between the slider and the slide groove when the handheld lever rotates relative to the first rotating part. Multiple positioning holes are arranged in an arc shape to correspond to the arc-shaped movement trajectory of the locking block provided on the mounting surface of the first rotating part, thereby accommodating the rotation of the handheld lever with the mounting plate relative to the first rotating part, allowing the locking block to smoothly engage with the positioning holes.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0068] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0069] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0070] The following is combined Figures 1-9 The following describes embodiments of the present invention.

[0071] According to an embodiment of this utility model, a scraping cleaning tool is provided, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, it includes: a scraping head 1, a hand handle 2, and a rotating assembly.

[0072] The handle 2 is rotatably mounted on the scraping head 1 via a rotating assembly, allowing the handle 2 to rotate relative to the scraping head 1 along its width direction to change the angle between the handle 2 and the scraping head 1. The rotating assembly, driven by the handle 2, can rotate circumferentially, switching between an unlocked and locked state. When the rotating assembly is unlocked, the handle 2 can rotate relative to the scraping head 1 along its width direction to change the angle between them. When the rotating assembly is locked, the rotation of the handle 2 along the width direction of the scraping head 1 is restricted.

[0073] In the above embodiment, a rotating component is provided between the handheld lever 2 and the scraping head 1, so that the handheld lever 2 can rotate along the width direction of the scraping head 1 to change the scraping angle of the scraping head 1. At the same time, the rotating component can be unlocked by rotating along its own circumference driven by the handheld lever 2, so that the user can rotate the handheld lever 2 along the width direction of the scraping head 1 at any time to adjust the scraping angle of the scraping head 1 for user convenience.

[0074] In this embodiment, the scraping cleaning tool can be a floor scraper, a window scraper, etc. The length direction of the scraper head 1 is parallel to... Figure 2 The rotating shaft 301 of the scraping cleaning tool shown is oriented in the same direction, and the width direction of the scraping head 1 is the same as that of the rotating shaft 301. Figure 3 The rotating shaft 301 in the scraping cleaning tool shown has the same orientation.

[0075] Specifically, when the rotating assembly is driven by the handle 2 to rotate circumferentially, the connection between the rotating assembly and the scraper head 1 employs a friction fit, or a fit assembly of elastic protrusions and grooves, to prevent the scraper head from accidentally rotating relative to the handle via the rotating assembly during the use of the scraping cleaning tool. The rotating assembly is driven by the handle 2 to rotate circumferentially, allowing the rotating assembly to rotate to... Figure 2 The unlock status shown, and Figure 3 The locked state is shown.

[0076] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the rotating component has a first position and a second position. When the rotating component rotates in the first position and the second position along its own circumference, the unlocked state and the locked state of the rotating component can be switched. When the rotating component is in the first position, the rotating component is in the unlocked state. When the rotating component is in the second position, the rotating component is in the locked state.

[0077] In the above embodiments, when the rotating component is in the first position, the rotating component is in the unlocked state, and the hand lever 2 can rotate relative to the scraping head 1 along the width direction of the scraping head 1; when the rotating component is in the second position, the rotating component is in the locked state, and the rotation of the hand lever 2 along the width direction of the scraping head 1 is restricted.

[0078] Specifically, this embodiment does not limit the size of the included angle between the first position and the second position.

[0079] In one implementation, the angle between the first position and the second position is 90°. When the rotating component is in the first position, the handle 2 rotates relative to the rotating component and is located directly in front of or behind the scraping head 1; when the rotating component is in the second position, the handle 2 rotates relative to the rotating component and is located to the left or right of the scraping head 1.

[0080] In another implementation, the angle between the first position and the second position is greater than 0 and not greater than 90°. When the rotating component is in the first position, the handle 2 rotates relative to the rotating component and is located directly in front of or behind the scraping head 1; when the rotating component is in the second position, the handle 2 rotates relative to the rotating component and is located diagonally in front of or diagonally behind the scraping head 1.

[0081] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, in a preferred embodiment, the included angle between the first position and the second position is 90°.

[0082] In the above embodiment, the included angle between the first position and the second position is set to 90°. The rotating component can be switched between the unlocked state and the locked state by driving the rotating component to rotate 90° by the hand lever 2.

[0083] Specifically, when the rotating component is in the first position, the handle 2 rotates relative to the rotating component and is positioned directly in front of or behind the scraping head 1; when the rotating component is in the second position, the handle 2 rotates relative to the rotating component and is positioned to the left or right of the scraping head 1. This facilitates the storage of the scraping cleaning tool.

[0084] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, when the rotating component is in the first position, the rotating component is in the unlocked state, and the rotation of the hand lever 2 along the length direction of the scraping head 1 is restricted; when the rotating component is in the second position, the rotating component is in the locked state, and the hand lever 2 can rotate relative to the scraping head 1 along the length direction of the scraping head 1.

[0085] In the above embodiment, the rotation of the hand handle 2 along the length direction of the scraping head 1 is restricted to facilitate the use of the scraping cleaning tool for water pushing operations; the hand handle 2 can rotate relative to the scraping head 1 along the length direction of the scraping head 1 to facilitate the use of the scraping cleaning tool for water scraping operations.

[0086] Specifically, when the rotating component is in the first position, the rotating component is in the unlocked state, and the rotation of the handle 2 along the length direction of the scraping head 1 is restricted, i.e. Figure 2 , Figure 4 As shown, at this time, the handle 2 cannot swing relative to the length of the scraper head 1, thus preventing the handle 2 from swinging during use and facilitating the user's use of the scraper cleaning tool for water pushing operations. Figure 4 In the current state, the angle between the handle 2 and the scraper head 1 is reduced. When using the scraper cleaning tool, the handle 2 can be tilted relative to the ground so that the scraper head 1 can almost vertically contact the ground, allowing for more efficient water pushing with less effort. When the rotating component is in the second position and locked, the handle 2 can rotate relative to the scraper head 1 along its length, i.e. Figure 3 , Figure 5As shown, the handle 2 can swing relative to the length of the squeegee head 1. This swinging motion of the handle 2 facilitates the user's use of the squeegee for wiping operations. Specifically, during wiping, the optimal wiping angle between the squeegee head 1 and the handle 2 changes as the distance between the squeegee head 1 and the user changes. The handle 2 and the squeegee head 1 can be adjusted along the length of the squeegee head 1. Users can directly adjust the angle of the handle 2 in real time by rotating it along the length of the squeegee head 1, based on their standing position and the distance to the wiping surface. This allows for real-time adjustment of the angle between the squeegee head 1 and the handle 2 to the optimal wiping angle, thus facilitating user operation and improving wiping performance.

[0087] Furthermore, the current design of adjusting the angle of the handle 2 along the length of the squeegee head 1 only considers adjusting the angle of the handle 2 relative to the squeegee head 1 during squeegee operation. When the squeegee needs to be used for pushing water, this embodiment, through the design of the rotating component being driven by the handle 2 to rotate circumferentially, can easily and quickly switch between the first and second positions of the rotating component. This allows users to quickly switch between the squeegee operation state and the pushing water operation state according to different usage scenarios. In both states, the handle 2 can be adjusted relative to the squeegee head 1 in the corresponding direction, thus ensuring that the user can adjust the angle between the squeegee head 1 and the handle 2 to the optimal wiping angle in both different usage states.

[0088] In some embodiments, such as Figure 2 , Figure 3 , Figure 6 As shown, the rotating assembly includes a first rotating part 3 and a second rotating part 4 connected to each other. The handle 2 is rotatably connected to the scraping head 1 through the first rotating part 3 and the second rotating part 4. The first rotating part 3 is rotatably connected to the handle 2 through a rotating shaft 301, so that the handle 2 is rotatably mounted on the scraping head 1 and can rotate relative to the scraping head 1 about the axis of the rotating shaft 301. The second rotating part 4 is circumferentially connected to the scraping head 1 and can rotate relative to the scraping head 1 in its own circumferential direction, so that when the handle 2 rotates in its own circumferential direction, it can drive the first rotating part 3 and the second rotating part 4 to rotate synchronously in the circumferential direction, thereby driving the rotating shaft 301 to rotate in the circumferential direction, so that the rotating assembly rotates to an unlocked state or a locked state. When the rotating assembly is in the unlocked state, the axial direction of the rotating shaft 301 is parallel to the length direction of the scraping head 1. When the rotating assembly is in the locked state, the axial direction of the rotating shaft 301 is not parallel to the length direction of the scraping head 1.

[0089] In the above embodiment, the hand lever 2 and the scraping head 1 are connected by the first rotating part 3 and the second rotating part 4 connected to each other. The rotating shaft 301 of the first rotating part 3 is rotatably connected to the hand lever 2, so that the hand lever 2 can rotate closer to or away from the scraping head 1. The circumferential rotation of the second rotating part 4 and the scraping head 1 is connected to realize the rotation of the hand lever 2 relative to the scraping head 1 along its own circumference.

[0090] Specifically, when the rotating assembly is in the unlocked state, the axial direction of the rotating shaft 301 is parallel to the length direction of the scraping head 1, i.e. Figure 2 As shown, when a lateral force perpendicular to the handle 2 is applied, since the rotation of the rotating shaft 301 is unrestricted, the handle 2 can rotate relative to the first rotating part 3 and the scraping head 1 along the width direction of the scraping head 1; when the rotating assembly is in the locked state, the axial direction of the rotating shaft 301 is not parallel to the length direction of the scraping head 1, that is, as shown... Figure 3 As shown, when a lateral force perpendicular to the hand lever 2 is applied to the hand lever 2, the rotation of the rotating shaft 301 is interfered with, and the hand lever 2 cannot rotate relative to the first rotating part 3 and the scraping head 1 in the width direction of the scraping head 1.

[0091] Furthermore, the fact that the axial direction of the rotating shaft 301 is not parallel to the length direction of the scraping head 1 can be specifically manifested in that the axial direction of the rotating shaft 301 is set at a 90° angle to the length direction of the scraping head 1, or at an angle greater than 0 and not greater than 90°. In this embodiment, the axial direction of the rotating shaft 301 is set at a 90° angle to the length direction of the scraping head 1.

[0092] In some embodiments, such as Figure 6 , Figure 7 As shown, the scraping head 1 is provided with a mounting groove 101, and the second rotating part 4 is inserted into the mounting groove 101 so that the second rotating part 4 is circumferentially connected to the scraping head 1.

[0093] In the above embodiment, a mounting groove 101 is provided in the scraping head 1 so that the second rotating part 4 can be inserted into the mounting groove 101, so that the second rotating part 4 and the scraping head 1 can be circumferentially rotated. The structure is simple and the connection is reliable.

[0094] Specifically, a fixing plate is provided at the middle position of the scraping head 1, and a mounting groove 101 is provided on the fixing plate. When the second rotating part 4 is inserted into the mounting groove 101, the outer wall of the second rotating part 4 is clearance-fitted with the inner wall of the mounting groove 101, thereby realizing the circumferential rotational connection between the second rotating part 4 and the scraping head 1.

[0095] It should be noted that the mounting groove 101 can be configured as a through groove that extends through the height direction of the scraper head 1, or a groove formed on the upper surface of the scraper head 1. This embodiment does not impose any restrictions.

[0096] In some embodiments, such as Figure 6 , Figure 7 As shown, one of the second rotating part 4 and the mounting groove 101 is provided with an annular groove 102, and the other is provided with a buckle 401; the second rotating part 4 is inserted into the mounting groove 101, so that the buckle 401 is engaged with the annular groove 102, and the annular groove 102 can rotate circumferentially relative to the buckle 401.

[0097] In the above embodiment, the second rotating part 4 and the mounting groove 101 are connected by the snap-fit ​​of the annular groove 102 and the buckle 401, which achieves the snap-fit ​​of the second rotating part 4 and the mounting groove 101 in a circumferential rotational fit. The structure is simple and the connection is reliable.

[0098] Specifically, in this embodiment, the outer wall of the second rotating part 4 is provided with a buckle 401, and the inner wall of the mounting groove 101 is provided with an annular groove 102. The buckle 401 is arranged along the entire circumference of the outer wall of the second rotating part 4, and the annular groove 102 is arranged along the entire circumference of the inner wall of the mounting groove 101.

[0099] In some embodiments, such as Figure 6 As shown, a one-way limiting mechanism is provided between the second rotating part 4 and the mounting groove 101 so that the second rotating part 4 can rotate unidirectionally relative to the scraping head 1.

[0100] In the above embodiment, a one-way limiting mechanism is provided between the second rotating part 4 and the mounting groove 101 to control the second rotating part 4 to rotate only in one direction relative to the scraping head 1, so as to avoid excessive wear between the second rotating part 4 and the inner wall of the mounting groove 101 when it is driven to rotate.

[0101] Specifically, the one-way limit mechanism can be designed as an electronic lock or a combination of ratchet and one-way groove.

[0102] In some embodiments, such as Figure 6 , Figure 8 , Figure 9 As shown, the one-way limiting mechanism includes at least one-way groove 103 and at least one limiting ratchet 402 that cooperate with each other. One of the at least one-way groove 103 and at least one limiting ratchet 402 is provided on the outer wall of the second rotating part 4, and the other is provided on the inner wall of the mounting groove 101. The second rotating part 4 rotates unidirectionally relative to the scraping head 1 through the snap-fit ​​cooperation of at least one-way groove 103 and at least one limiting ratchet 402.

[0103] In the above embodiment, the one-way rotational engagement between the second rotating part 4 and the mounting groove 101 is achieved through the one-way rotational engagement structure of the one-way groove 103 and the limiting ratchet 402, which is simple in structure and reliable in connection.

[0104] Specifically, in this embodiment, the limiting ratchet 402 is provided on the outer wall of the second rotating part 4, and the one-way groove 103 is provided on the inner wall of the mounting groove 101. There are two limiting ratchet 402 arranged opposite each other along the outer wall of the second rotating part 4, and four one-way grooves 103 are arranged along the inner wall of the mounting groove 101.

[0105] Furthermore, two limiting ratchet teeth 402 are respectively connected to a cantilever 403. The two cantilever 403 are connected as one unit by a spring plate 404 configured as S-shape. The spring plate 404 realizes the deformation and reset of the limiting ratchet teeth 402 along the radial direction of the second rotating part 4.

[0106] In some embodiments, the handheld lever 2 is configured as a multi-segment lever, and adjacent segments are threaded together; the direction in which the second rotating part 4 can rotate unidirectionally relative to the scraping head 1 is the same as the direction of the threaded connection between the segments.

[0107] In the above embodiment, the direction in which the second rotating part 4 can rotate unidirectionally relative to the scraping head 1 is the same as the direction of the threaded connection between the rods, so as to avoid the second rotating part 4 from loosening of multiple rod sections when rotating with the hand handle 2, and to ensure the structural stability of the scraping cleaning tool.

[0108] Specifically, the handheld lever 2 is designed as a multi-segment lever for easy packaging and transportation. The direction in which the second rotating part 4 can rotate unidirectionally relative to the scraping head 1 is the same as the direction of the threaded connection between the levers. When the handheld lever 2 is rotated to drive the second rotating part 4 to rotate, the winnowing basket lever 5 of the multi-segment lever will form a tighter threaded connection and will not loosen.

[0109] In some embodiments, a first limiting component is provided between the rotating component and the hand lever 2, the first limiting component limiting the maximum angle of rotation of the hand lever 2 relative to the scraping head 1.

[0110] In the above embodiment, a first limiting component is provided to limit the maximum angle of rotation of the handheld lever 2 towards or away from the scraper head 1, so as to avoid the rotation angle of the handheld lever 2 relative to the scraper head 1 being too large, which would affect the water pushing effect. At the same time, the rotation angle between the scraper head 1 and the handheld lever 2 is limited to ensure the structural stability of the scraping cleaning tool.

[0111] Specifically, when the rotation angle of the handle 2 relative to the scraping head 1 is too large, for example, when the handle 2 is at... Figure 2 or Figure 3 When the relative rotation of the scraping head 1 is close to 90°, and the hand handle 2 is almost parallel to the scraping surface when the scraping head 1 is perpendicular to the wiping surface, it will cause inconvenience for the user to operate when holding the hand handle 2, thus affecting the water pushing effect. Therefore, the first limiting component is needed to limit the maximum angle of rotation of the hand handle 2 towards or away from the scraping head 1.

[0112] Furthermore, as a preferred embodiment, the maximum angle of rotation of the hand handle 2 relative to the scraping head 1 is set as the optimal water-pushing angle. When the user uses the scraping cleaning tool, the hand handle 2 can automatically rotate to the optimal water-pushing angle with the user's water-pushing action, thereby achieving the best water-pushing effect of the scraping cleaning tool without the need for the user to make any adjustments, which is convenient and quick.

[0113] In some embodiments, such as Figure 6 As shown, the first limiting component includes a slider 302 and a groove 201 that cooperate with each other. One of the slider 302 and the groove 201 is provided on the rotating component, and the other is provided on the hand handle 2. When the slider 302 abuts against the end of the groove 201, it limits the maximum angle of rotation of the hand handle 2 relative to the scraping head 1.

[0114] In the above embodiment, the maximum angle of rotation of the hand handle 2 towards or away from the scraping head 1 is limited by the sliding cooperation of the slider 302 and the groove 201. The structure is simple and the cooperation is stable.

[0115] Specifically, the slider 302 is mounted on the first rotating part 3, and the groove 201 is mounted on the hand handle 2. At this time, when the hand handle 2 rotates to the point where the end of the groove 201 abuts against the slider 302 on the rotating assembly, it is the maximum angle of rotation of the hand handle 2 relative to the scraping head 1, which is also the optimal water pushing angle.

[0116] In some embodiments, a second limiting component is provided between the rotating component and the handheld lever 2, the second limiting component restricting the rotation of the handheld lever 2 relative to the scraping head 1, so as to fix the position of the handheld lever 2 relative to the scraping head 1.

[0117] In the above embodiment, a second limiting component is provided to limit the positioning position of the hand handle 2 to approach or move away from the rotating position of the scraping head 1, so as to fix the use position of the hand handle 2 and ensure the stability of the scraping cleaning tool.

[0118] Specifically, this embodiment does not limit the specific method by which the second limiting component restricts the rotation of the handheld lever 2 relative to the scraping head 1 for angle adjustment. In one embodiment, the second limiting component is configured as a friction surface between the rotating component and the handheld lever 2, utilizing friction to achieve stepless rotation between the rotating component and the handheld lever 2, thereby enabling the second limiting component to restrict the rotation of the handheld lever 2 relative to the scraping head 1 for angle adjustment. In another embodiment, the second limiting component is configured as a mating structure between a protrusion and multiple grooves or a groove and multiple protrusions between the rotating component and the handheld lever 2, achieving stepped rotation between the rotating component and the handheld lever 2 through the corresponding engagement of the protrusions and grooves, thereby enabling the second limiting component to restrict the rotation of the handheld lever 2 relative to the scraping head 1 for angle adjustment.

[0119] In some embodiments, such as Figure 6As shown, the second limiting component includes a locking block 303 and a plurality of spaced positioning holes 202. One of the locking block 303 and the plurality of spaced positioning holes 202 is located on the rotating component, and the other is located on the hand handle 2. After the hand handle 2 rotates relative to the rotating component, the locking block 303 can engage with one of the positioning holes 202 to fix the position of the hand handle 2 relative to the scraping head 1.

[0120] In the above embodiment, the locking block 303 and multiple spaced positioning holes 202 are used to lock together to limit the endpoint position of the hand lever 2 as it moves closer to or further away from the scraping head 1. The structure is simple and the fit is stable.

[0121] Specifically, the locking block 303 is disposed on the first rotating part 3, and multiple spaced positioning holes 202 are disposed on the hand handle 2. The positioning position refers to the locking position that the locking block 303 should be in after one adjustment. In this embodiment, there are three spaced positioning holes 202, and the locking block 303 can be locked into the three positioning holes 202 through multiple adjustments, that is, it is in three positioning positions respectively.

[0122] In some embodiments, such as Figure 6 As shown, when the scraping cleaning tool is provided with a first limiting component and a second limiting component, and the rotating component includes a first rotating part 3 and a second rotating part 4, the first limiting component and the second limiting component are located between the first rotating part 3 and the hand handle 2.

[0123] In the above embodiment, the first limiting component and the second limiting component are disposed between the first rotating part 3 and the hand handle 2 to achieve a stable connection between the first limiting component and the second limiting component between the rotating part and the hand handle 2.

[0124] In some embodiments, such as Figure 6 As shown, the first rotating part 3 has two mounting surfaces 304 facing away from each other, and the hand handle 2 has two mounting plates 203 facing each other at one end near the first rotating part 3. An installation space is formed between the two mounting plates 203. The first rotating part 3 is located in the installation space, and the first limiting component and the second limiting component are located between the mounting surface 304 and the mounting plate 203.

[0125] In the above embodiment, the mounting space formed between the two mounting plates 203 on the handheld lever 2 provides a mounting position for the first rotating part 3, so that the first rotating part 3 can be embedded between the two mounting plates 203 to form a stable installation.

[0126] Specifically, each of the two opposing mounting plates 203 has a shaft hole. A rotating shaft 301 is located in the first rotating part 3, with both ends extending out from the two opposing mounting surfaces 304, thus forming a rotatable connection with the corresponding shaft holes on the two mounting plates 203, thereby realizing the rotatable connection between the handheld lever 2 and the first rotating part 3. Clearance spaces are formed on both sides of the two mounting plates 203 to allow the handheld lever 2 to avoid the first rotating part 3 when rotating. The respective mating structures on the first limiting assembly and the second limiting assembly are distributed between the mounting surfaces 304 and the mounting plates 203 to form a limiting fit and a snap-fit ​​fit.

[0127] In some embodiments, such as Figure 6 As shown, when the first limiting component includes a slider 302 and a groove 201, the slider 302 is disposed on the mounting surface 304, and the groove 201 is disposed on the mounting plate 203; the groove 201 is constructed as an arc-shaped structure, and the center of the arc-shaped structure is coaxially disposed with the rotation shaft 301 connecting the first rotating part 3 and the hand handle 2.

[0128] In the above embodiment, the slide groove 201 is constructed as an arc-shaped structure to accommodate the rotation of the hand lever 2 with the mounting plate 203 relative to the first rotating part 3, so as to avoid positional interference between the slider 302 and the slide groove 201 when the hand lever 2 rotates relative to the first rotating part 3.

[0129] Specifically, the two mounting plates 203 are designed to be deformable. When the handle 2 is installed with the first rotating part 3, the two mounting plates 203 can be opened by the contact of the slider 302 on the mounting surface 304, and then reset after the slider 302 is embedded in the slide groove 201, so that the slider 302 can be smoothly assembled into the slide groove 201 to form a limiting fit. Alternatively, the slider 302 on the mounting surface 304 is designed to be deformable. When the handle 2 is installed with the first rotating part 3, the slider 302 can be compressed and deformed by the contact of the mounting surface 304, and reset its position in the slide groove 201 to embed into the slide groove 201, so that the slider 302 can be smoothly assembled into the slide groove 201 to form a limiting fit.

[0130] In some embodiments, such as Figure 6 As shown, multiple slide grooves 201 are provided, and the multiple slide grooves 201 are centrally symmetrically arranged with the rotation axis 301 as the center. Multiple sliders 302 are provided corresponding to the multiple slide grooves 201.

[0131] In the above embodiment, a plurality of centrally symmetrical grooves 201 are provided with the rotation axis 301 as the center, and a plurality of sliders 302 are provided accordingly to improve the stability of the hand handle 2 rotating relative to the first rotating part 3.

[0132] Specifically, in this embodiment, each of the two mounting plates 203 is provided with two arc-shaped sliding grooves 201, and correspondingly, each of the mounting surfaces 304 is provided with two sliders 302.

[0133] In some embodiments, such as Figure 6 As shown, when the second limiting component includes a locking block 303 and a positioning hole 202, the locking block 303 is located on the mounting surface 304, and the positioning hole 202 is located on the mounting plate 203; the multiple positioning holes 202 are distributed in an arc shape, and the center of the arc is coaxially arranged with the rotation shaft 301 connecting the first rotating part 3 and the hand handle 2.

[0134] In the above embodiment, the multiple positioning holes 202 are arranged in an arc shape to correspond to the arc-shaped movement trajectory of the locking block 303 provided on the mounting surface 304 of the first rotating part 3, so as to cooperate with the rotation of the hand handle 2 with mounting plate 203 relative to the first rotating part 3, so that the locking block 303 can be smoothly engaged with the positioning hole 202.

[0135] Specifically, after the handheld lever 2 rotates relative to the rotating assembly, the locking block 303 can engage with one of the positioning holes 202 to fix the position of the handheld lever 2 relative to the scraping head 1. In this embodiment, each of the two mounting plates 203 is provided with three positioning holes 202 arranged in an arc shape, and correspondingly, each mounting surface 304 is provided with a locking block 303.

[0136] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
