[0087] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0088] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0089] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0090] See appendix Figure 1 - Appendix Figure 27 This utility model proposes a scraper, which includes: a scraper body 1 and a scraper component 2. The scraper body 1 is provided with a first blade 31; the scraper component 2 is provided with a second blade 32; the width of the second blade 32 is not equal to that of the first blade 31; the scraper can switch between using the first blade 31 and using the second blade 32; when the scraper body 1 and the scraper component 2 are in a separated state or the scraper component 2 is stored in the scraper body 1, the first blade 31 is in a usable state; when the scraper body 1 and the scraper component 2 are in an assembled state or the scraper component 2 extends from the scraper body 1, the second blade 32 is in a usable state.

[0091] Specifically, the width of the second blade 32 can be set to be greater than the width of the first blade 31. In some embodiments, the width of the second blade 32 can be further limited to twice the width of the first blade 31, or two first blades 31 can be mounted side by side on the scraper component 2 to serve as the second blade 32. This method facilitates the management, purchase, and use of blades, allowing users to use the scraper by purchasing only a single type of blade. Different widths of the first blade 31 and the second blade 32 allow users to select the corresponding first blade 31 or second blade 32 according to their usage needs, thus meeting diverse user requirements. By detaching the scraper component 2 from the scraper body 1 or housing the scraper component 2 on the scraper body 1, the first blades 31 on the scraper body 1 are exposed and in a usable state. Holding the scraper body 1 allows... The first blade 31 can be pushed for use. Conversely, by assembling the scraper component 2 onto the scraper body 1 in a predetermined manner or switching the scraper component 2 from being housed within the scraper body 1 to extending beyond the scraper body 1, the second blade 32 is exposed and put into use. At this time, the second blade 32 can be pushed for use by holding the scraper body 1. In summary, by using the first blade 31 and the second blade 32 with different widths, the user's needs for different work scenarios can be met. During use, only the connection between the scraper body 1 and the scraper component 2 needs to be switched to quickly switch between blades of different widths, so that the first blade 31 or the second blade 32 is in a usable state for work. There is no need to repeatedly change different styles of scrapers or change blades of different widths on the scraper, thereby improving the user experience.

[0092] It should also be noted that the scraper body 1 also includes a handle 1a for the user to hold. To improve the user's grip, the handle 1a can be designed as follows: Figure 1 , Figure 2 and Figure 3 The arc-shaped strip structure shown can also have anti-slip protrusions on the surface of the handle 1a to increase the stability when the user holds it; in other embodiments, the width of the first blade 31 can be set to be greater than the width of the second blade 32. In this case, the scraper component 2 can be assembled on the end of the scraper body 1 away from the first blade 31, or a cavity that can adapt to the larger width of the first blade 31 can be provided on the end of the scraper component 2 away from the second blade 32.

[0093] For ease of explanation, the scraper is defined to have multiple states based on the connection between the scraper body 1 and the scraper component 2:

[0094] When the scraper is in its original working state, the scraper component 2 is separated from the scraper body 1 or the scraper component 2 is housed in the scraper body 1. At this time, the first blade 31 is in a usable state, and the user can use the first blade 31 on it for work by holding the scraper body 1.

[0095] When the scraper is in the first assembly state, the second assembly state, and the third assembly state, the scraper component 2 is assembled on the scraper body 1 or extends from the scraper body 1. At this time, the user can use the second blade 32 on the scraper component 2 by holding the scraper body 1, or the first blade 31 and the second blade 32 can be used alternately, as described in the third assembly state below.

[0096] In some embodiments, when the scraper is in its original working state, the scraper component 2 is detached from the scraper body 1 or housed within a predetermined cavity of the scraper body 1; such as Figure 2 As shown, when the scraper is in its original working state, the scraper component 2 is completely detached from the scraper body 1. At this time, the scraper component 2 can be stored in the user's work bag or similar location, and the user can hold the scraper body 1 and use the first blade 31 fixed at its end for cleaning work; Figure 24 , Figure 27 As shown, when the scraper is in its original working state, the scraper component 2 can also be housed in a preset cavity of the scraper body 1, as described in Embodiments 9 and 10, and will not be elaborated here.

[0097] In some embodiments, when the scraper is in the first assembled state, the scraper component 2 is pivotally connected to the scraper body 1, and the scraper component 2 serves as an extension of the scraper body 1. The first blade 31 is housed within a predetermined cavity of the scraper component 2, such that the cutting edges of the second blade 32 and the first blade 31 both face outwards along one end of the scraper body 1, and the first and second blades 31 and 32 face the same direction. This prevents the cutting edges of the blades from pointing towards the user's hand when the user holds the scraper body 1 to use the scraper, making it easier for the user to grip and exert force, and also preventing the blades from causing injury to the user. In other embodiments, the scraper component 2 can also be connected to the end of the scraper body 1 away from the first blade 31. In this case, the length of the scraper body 1 can be set as long as possible to avoid the first blades 31 and the second blades 32 at both ends interfering with the user's hand.

[0098] Reference Figure 5 and Figure 8In some embodiments, both the scraper body 1 and the scraper component 2 are provided with a mounting structure 5 for mounting a first blade 31 or a second blade 32. The mounting structure 5 includes a first mounting wall 51 and a second mounting wall 52. The first blade 31 or the second blade 32 is inserted between the first mounting wall 51 and the second mounting wall 52. Specifically, the area of ​​the first mounting wall 51 is larger than the area of ​​the second mounting wall 52. The first mounting wall 51 is used to fit the first blade 31 or the second blade 32 over a large area to improve the stability of the first blade 31 or the second blade 32 on the mounting structure 5, and the large area... The close fit helps improve the service life of the blades, making the first blade 31 or the second blade 32 less prone to breakage. The smaller area of ​​the second mounting wall 52 limits the first blade 31 or the second blade 32 in the thickness direction, preventing the blades from detaching from the mounting structure 5. Simultaneously, the smaller area of ​​the second mounting wall 52 also facilitates blade replacement by the user. To further improve the stability of the first blade 31 and the second blade 32 on their mounting structure 5, in some embodiments, the first mounting wall 51 is provided with a first limiting strip 510. The first limiting strip 510 is provided with a plurality of first limiting slots 511 spaced apart along its length, and first limiting protrusions 512 are provided at both ends of the first limiting strip 510. The first blade 31 and the second blade 32 are each provided with a second limiting slot 310 that mates with the first limiting strip 510, a plurality of second limiting protrusions 311 that mate with the plurality of first limiting slots 511, and a third limiting slot 312 that mates with the first limiting protrusions 512. The second limiting slots 310 extend through the blade along its width, and the third limiting slots 312 are distributed at both ends of the second limiting slots 310. The engagement of the second limiting groove 310 with the first limiting strip 510 prevents the blade from detaching from the mounting structure 5 in the pushing direction when the user pushes the blade for scraping. The engagement of the third limiting groove 312 with the first limiting protrusion 512, and the engagement of the first limiting groove 511 with the second limiting protrusion 311, limits the blade's width. Through multiple interlocking protrusions and grooves, multi-directional restrictions are achieved in both the blade's width and the scraper's pushing direction, thereby improving the connection stability between the first blade 31 and its mounting structure 5, and between the second blade 32 and its mounting structure 5. In other embodiments, the first blade 31 and the second blade 32 can also be fixed to corresponding positions on the scraper body 1 and the scraper component 2 via screw thread connections.

[0099] Reference Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7In some embodiments, the scraper body 1 includes a connecting end 10, a first blade 31 is mounted on the connecting end 10, and the scraper component 2 has a connecting cavity 20 with an opening 200 communicating with the outside. The connecting end 10 can be inserted into the connecting cavity 20 through the opening 200. When the scraper is in the first assembly state, the connecting end 10 is inserted into the connecting cavity 20, and the first blade 31 is housed within the connecting cavity 20, making the first blade 31 unusable. Specifically, the connecting end 10 is provided with a mounting structure 5 for fixing the first blade 31, so that when the connecting end 10 is inserted into the connecting cavity 20, the first blade 31 can be housed within the connecting cavity 20, thereby improving efficiency. The compact structure of the scraper ensures that the first blade 31 is not interfered with when the second blade 32 is in use, and also protects the first blade 31. In addition, the connecting cavity 20 and the second blade 32 are distributed at opposite ends of the scraper component 2, so that when the connecting end 10 is inserted into the connecting cavity 20, the scraper component 2 is an extension of the scraper body 1. This allows the scraper body 1 to be held in the same gripping direction and gripping method, whether the scraper is in its original working state or its first assembly state, so as to control the first blade 31 or the second blade 32 of the scraper for cleaning work, thus maintaining the uniformity and consistency of the scraper's operation.

[0100] Reference Figure 3 , Figure 6 , Figure 7 , Figure 10 and Figure 14 In some embodiments, the connecting cavity 20 has opposing bottom walls 203 and top walls 204, and the connecting end 10 has a bottom surface 100 and a top surface 101. When the scraper is in the first assembly state, the bottom surface 100 faces the bottom wall 203, and the top surface 101 faces the top wall 204. Specifically, the bottom walls 203 can be fitted with the bottom surface 100, and the top wall 204 can be fitted with the top surface 101. The surface fitting method can improve the stability of the connecting end 10 in the connecting cavity 20 and avoid significant shaking of the scraper component 2 during use.

[0101] Reference Figure 3In some embodiments, the cavity wall of the connecting cavity 20 is provided with a first limiting hole 205, and the connecting end 10 is provided with a first limiting protrusion 102. When the scraper is in the first assembly state, the first limiting protrusion 102 is engaged with the first limiting hole 205. Specifically, the first limiting hole 205 can be opened on any cavity wall of the connecting cavity 20. In some embodiments, the first limiting hole 205 can be opened on the bottom wall 203 of the connecting cavity 20. By engaging the first limiting protrusion 102 with the first limiting hole 205, the connecting end 10 can be prevented from detaching from the connecting cavity 20 through the opening 200, so that the connecting end 10 is not easily detached from the connecting cavity 20 through the opening 200 when the scraper body 1 is not pulled outward with force. It should also be noted that in other embodiments, the first limiting hole 205 can also be a groove or protrusion structure opened on the inner wall of the connecting cavity 20 that can engage with the first limiting protrusion 102.

[0102] Reference Figure 7 In some embodiments, the connecting cavity 20 includes a first cavity 201 and a second cavity 202 connected together. The second cavity 202 is located on the side of the first cavity 201 away from the opening 200. The thickness of the first cavity 201 is greater than the thickness of the second cavity 202, so that the inner wall of the first cavity 201 near the second cavity 202 is recessed to form a limiting surface 2010 facing the opening 200. Specifically, the length, width, and thickness of the first cavity 201 are approximately the same as those of the connecting end 10, so that after the connecting end 10 is inserted into the connecting cavity 20, the outer wall of the connecting end 10 and the first cavity 201 are mutually locked, thereby improving the stability of the connection. In addition, when the scraper is in the first assembly state, the first blade 31 is placed in the second cavity 202, and the end wall of the connecting end 10 and the limiting surface are... The first blade 31 is abutted against the second cavity 202 to restrict the movement of the connecting end 10 into the second cavity 202. The depth of the second cavity 202 is greater than the distance by which the first blade 31 extends out of the connecting end 10, and the thickness of the second cavity 202 is greater than the thickness of the first blade 31. This prevents the first blade 31 from abutting against the inner wall of the second cavity 202, thus avoiding the situation where the first blade 31 will collide and break after the connecting end 10 is inserted into the connecting cavity 20. In addition, the limiting surface 2010 is a smooth arc-shaped surface. When the connecting end 10 is inserted into the first cavity 201, the first blade 31 on it may abut against the limiting surface 2010. By setting the limiting surface 2010 to a smooth arc-shaped surface, it is beneficial to guide the first blade 31 into the second cavity 202 and avoid damage to the first blade 31 caused by rough or flat surfaces.

[0103] Reference Figures 9-14In some embodiments, the scraper also has a second assembly state and a third assembly state. Specifically, a second limiting hole 206 is provided on the top wall 204 of the connecting cavity 20. Both the first limiting hole 205 and the second limiting hole 206 communicate with the connecting cavity 20. The minimum distance between the second limiting hole 206 and the second blade 32 is not equal to the minimum distance between the first limiting hole 205 and the second blade 32. Specifically, the thickness direction of the connecting cavity 20 is defined as follows: Figure 3 and Figure 7 The first direction D1 shown is defined as the direction perpendicular to the first direction D1 and extending from the second blade 32 to the opening 200 of the connecting cavity 20 as follows: Figure 3 and Figure 7 In the second direction D2 shown, the bottom wall 203 and the top wall 204 are spaced apart and opposite each other in the first direction D1. The first limiting hole 205 and the second limiting hole 206 are offset in the second direction D2. Specifically, the minimum distance between the first limiting hole 205 and the second blade 32 is set to be greater than the minimum distance between the second limiting hole 206 and the second blade 32, so that after the connecting end 10 passes through the first limiting hole 205 in the direction 206 towards the second limiting hole, the cutting edges of the first blade 31 and the second blade 32 face the same direction. When the scraper is in the second assembly state, the connecting end 10 passes through the first limiting hole 205, the connecting cavity 20, and the second limiting hole 206, with the bottom surface 100 of the connecting end 10 facing the scraper component 2. The second blade 32 is in a usable state, and the second blade 32 forms a first included angle α with the bottom surface 100. When the scraper is in the third assembly state, the connecting end... The connecting end 10 passes through the first limiting hole 205, the connecting cavity 20, and the second limiting hole 206. The top surface 101 of the connecting end 10 faces the scraper component 2. Both the first blade 31 and the second blade 32 are in a usable state, and the second blade 32 forms a second included angle β with the top surface 101, and the angle of the second included angle β is greater than the angle of the first included angle α. In summary, the second and third assembly states of the scraper are different from the aforementioned first assembly state. In the first assembly state of the scraper, the scraper component 2 is an extension structure of the scraper body 1, and there is no included angle between the second blade 32 and the scraper body 1. However, the second and third assembly states of the scraper are both included angles of different angles, so that the scraper can be used to clean working surfaces with different tilt angles. Users can switch the working state of the scraper as needed to meet the diverse work needs of users and improve the user experience.

[0104] It should also be noted that the mounting structure 5 on the scraper body 1 is specifically distributed on the bottom surface 100 of the connecting end 10, that is, the first mounting wall 51 is a structure formed on the bottom surface 100 of the connecting end 10, making the bottom surface 100 of the connecting end 10 the main support surface of the first blade 31. When the scraper is in the second assembly state, the bottom surface 100 faces the scraper component 2, making the first blade 31 closer to the surface of the scraper component 2, which makes it inconvenient for the first blade 31 to work in this state. Conversely, when the scraper is in the third assembly state, the top surface 101 faces the scraper component 2, that is, the bottom surface 100 faces away from the scraper component 2. At this time, the first blade 31 can be used as follows: Figure 13 The blade is used in the posture shown, and the force on the first blade 31 is roughly the same as in the original working state.

[0105] Reference Figure 7 , Figure 10 and Figure 14 In some embodiments, the first limiting hole 205 includes a first inclined wall 2051 and a second inclined wall 2052 facing each other, and the second limiting hole 206 includes a third inclined wall 2060 coplanar with the second inclined wall 2052; when the scraper is in the second assembly state, the bottom surface 100 of the connecting end 10 is in contact with the second inclined wall 2052 and the third inclined wall 2060, and the top surface 101 of the connecting end 10 is in contact with the first inclined wall 2051; when in the third assembly state, the bottom surface 100 of the connecting end 10 is in contact with the first inclined wall 2051, and the top surface 101 of the connecting end 10 is in contact with the second inclined wall 2052 and the third inclined wall 2060.

[0106] Specifically, the first inclined wall 2051, the second inclined wall 2052, and the third inclined wall 2060 are all inclined toward the second blade 32, so that after the connecting end 10 passes through the first limiting hole 205 and the second limiting hole 206, the cutting edges of the second blade 32 and the first blade 31 are roughly in the same direction. This allows the user to use the scraper in the second and third assembly states in the same way as in the original working state, maintaining the consistency of the scraper during use. In addition, the staggered first limiting hole 205 and the second limiting hole 206 can improve the stability of the connecting end 10 through which it passes, so that the top surface 101 and the bottom surface 100 of the connecting end 10 are both subjected to the pressure from the scraper component 2. The design of the first inclined wall 2051, the second inclined wall 2052, and the third inclined wall 2060 further increases the force-bearing area between the connecting end 10 and the scraper component 2, thereby improving the overall structural stability of the scraper in the second and third assembly states.

[0107] Reference Figure 10 and Figure 11In some embodiments, the bottom surface 100 of the connecting end 10 is provided with a first limiting groove 103, and the third inclined wall 2060 is provided with a second limiting protrusion 2061 that engages with the first limiting groove 103. The engagement of the first limiting groove 103 and the second limiting protrusion 2061 keeps the scraper in a second assembly state. In use, by inserting the connecting end 10 along the direction from the first limiting hole 205 to the second limiting hole 206, the first limiting groove 103 engages with the second limiting protrusion 2061, preventing the connecting end 10 from moving along the insertion direction. When the user holds the scraper body 1 and pushes the scraper, the connecting end 10 is constrained by the misaligned first limiting hole 205 and second limiting hole 206, as well as the engagement of the first limiting groove 103 and the second limiting protrusion 2061, and is stably maintained in the second assembly state, so that the scraper component 2 will not detach from the scraper body 1 during use.

[0108] Reference Figure 12 and Figure 14 In some embodiments, when the scraper is in the third assembly state, the first limiting protrusion 102 is placed in the connecting cavity 20 and abuts against the top wall 204 to restrict the connecting end 10 from disengaging from the scraper component 2 through the second limiting hole 206. Since the bottom surface 100 of the connecting end 10 itself is provided with the first limiting protrusion 102, in addition to engaging with the first limiting hole 205, the first limiting protrusion 102 can also be used to maintain the third assembly state of the scraper, making the scraper structure highly reusable. Specifically, when the connecting end 10 is inserted from the first limiting hole 205 into the second limiting hole 206, after the first blade 31 penetrates the second limiting hole 206, the first limiting protrusion 102 abuts against the top wall 204 of the connecting cavity 20, thereby restricting the connecting end 10 from continuing to move in the insertion direction, so as to ensure that when the user holds the scraper body 1 and pushes it, the scraper component 2 will not disengage from the scraper body 1, and the second blade 32 can be stably used for cleaning work.

[0109] Reference Figure 14 In some embodiments, the bottom surface 100 of the connecting end 10 is provided with a third limiting protrusion 104. When the scraper is in the third assembly state, the third limiting protrusion 104 is placed outside the connecting cavity 20 and abuts against the inner wall of the second limiting hole 206 to restrict the connecting end 10 from disengaging from the scraper component 2 through the second limiting hole 206. Specifically, the third limiting protrusion 104 and the first limiting protrusion 102 are spaced apart in the length direction of the connecting end 10, so that when the scraper is in the third assembly state, the third limiting protrusion 104 is placed outside the connecting cavity 20 and abuts against the hole wall of the second limiting hole 206, and the first limiting protrusion 102 is placed inside the connecting cavity 20 and abuts against its top wall 204, forming an inner and outer abutment restriction, thereby making the scraper stably maintained in the third assembly state.

[0110] It should also be noted that in some embodiments, the scraper component 2 has a through-hole, which is not connected to the connecting cavity 20. When the connecting end 10 passes through the through-hole, the first blade 31 and / or the second blade 32 are in a usable state. Specifically, the structure of the through-hole is roughly the same as that of the first limiting hole 205 and the second limiting hole 206 mentioned above. The difference is that the through-hole is not connected to the connecting cavity 20. The through-hole extends along the thickness direction of the scraper component 2. For ease of understanding, one end of the through-hole can be regarded as the first limiting hole 205 and the other end as the second limiting hole 206. The cavity between the two ends can be regarded as the connecting cavity 20. The wall of the through-hole can be provided with a protrusion or groove structure for engaging with the connecting end 10.

[0111] Reference Figure 15 In some embodiments, the connecting cavity 20 has a longitudinally opening 200 and a transversely opening 207. The lateral opening 207 is located between the opening 200 and the second blade 32 and penetrates the side wall of the connecting cavity 20. The connecting end 10 can be inserted into the connecting cavity 20 through the lateral opening 207. Through the lateral opening 207 and the opening 200, the connecting end 10 can be inserted into the connecting cavity 20 through its width direction. The design of the lateral opening 207 allows the connecting end 10 to be inserted into the connecting cavity 20 of the scraper component 2 more quickly and to be quickly removed from the connecting cavity 20. This method can switch the scraper from its original working state to its first assembly state more quickly.

[0112] Reference Figure 16 and Figure 17 In some embodiments, the connecting end 10 is provided with at least two elastic buckles 105, and the inner wall of the connecting cavity 20 is provided with at least two locking through holes 208. The at least two elastic buckles 105 are engaged with the at least two locking through holes 208 in a one-to-one correspondence, so that the scraper is kept in the first assembly state. Specifically, the elastic buckle 105 is composed of a spring sheet and a protrusion on the spring sheet that are opened on any outer wall of the connecting end 10. When the connecting end 10 is inserted into the connecting cavity 20, the elastic buckle 105 is squeezed by the cavity wall of the connecting cavity 20 and undergoes elastic deformation. When it is inserted into the locking through hole 208, the elastic buckle 105 is naturally engaged with the locking through hole 208, so that the scraper is in the first assembly state. Conversely, by pressing the part of the elastic buckle 105 exposed by the locking through hole 208, it can be disengaged from the locking through hole 208, and then the connecting end 10 can be pulled out of the connecting cavity 20, so that the scraper is in the original working state.

[0113] It should also be noted that the two elastic buckles 105 are spaced apart on the same outer wall of the connecting end 10, specifically as follows: Figure 16As shown, the snap fasteners can be distributed on the top surface 101 of the connecting end 10, and corresponding locking through holes 208 can be formed on the top wall 204 of the connecting cavity 20; or, two elastic snap fasteners 105 can be distributed on the two opposite outer walls of the connecting end 10, as shown in the figure. Figure 17 As shown, the elastic buckles 105 are distributed on the two side walls in the thickness direction of the connecting end 10. This method allows the user to press the elastic buckles 105 on both sides with one hand to release the elastic buckles 105 from the locking through hole 208.

[0114] Reference Figure 19 In some embodiments, the scraper also includes a limiting bolt 400. The connecting end 10 is provided with a limiting screw hole 106. The limiting bolt 400 passes through the cavity wall of the connecting cavity 20 and is threaded to the limiting screw hole 106, so that the scraper is kept in the first assembly state. The limiting bolt 400 can be specifically set as two or more. Through holes can be opened on the connecting cavity 20 corresponding to the limiting screw hole 106. After the connecting end 10 is inserted into the connecting cavity 20, the limiting bolt 400 can be threaded through the through hole and threaded to the limiting screw hole 106, thereby keeping the scraper in the first assembly state.

[0115] Reference Figure 18 In some embodiments, the outer wall of the connecting end 10 is provided with an annular groove 107, and the inner wall of the connecting cavity 20 is provided with an annular protrusion 209 that engages with the annular groove 107. When the scraper is in the first assembly state, the annular protrusion 209 engages with the annular groove 107. The engagement of the annular protrusion 209 with the annular groove 107 ensures that the connecting end 10 and the connecting cavity 20 are subjected to uniform force in the circumferential direction, making the connection between the two more stable. It should also be noted that the annular groove 107 can also be provided on the inner wall of the connecting cavity 20, and the annular protrusion 209 can be provided on the outer wall of the connecting end 10, thereby engaging the connecting end 10 and the connecting cavity 20.

[0116] Reference Figure 20 and Figure 21 In some embodiments, the scraper also includes at least two magnetic elements 401, which are respectively fixed to the connecting end 10 and the connecting cavity 20. When the scraper is in the first assembly state, the two magnetic elements 401 are magnetically attracted to each other. Specifically, for ease of installation, the top wall 204 of the connecting cavity 20 can be removed to form an open cavity, and a magnetic element 401 can be installed on the bottom wall 203 of the connecting cavity 20, and another magnetic element 401 can be installed on the bottom surface 100 of the connecting end 10. The magnetic attraction of the two magnetic elements 401 makes it difficult for the scraper component 2 to detach from the scraper body 1 in its thickness direction. In addition, an L-shaped hook 15 can be provided on the bottom surface 100 of the connecting end 10. When the scraper is in the first assembly state, the L-shaped hook 15 is engaged with the bottom wall 203 of the connecting cavity 20, further improving the connection stability between the scraper component 2 and the scraper body 1 in its thickness direction.

[0117] Reference Figure 22 In some embodiments, the scraper body 1 includes an insertion hole 11, and the scraper component 2 includes a snap fastener 21 and a first receiving groove 22. One end of the scraper body 1 on which the first blade 31 is mounted and the first blade 31 can be accommodated within the first receiving groove 22, and the snap fastener 21 engages with the insertion hole 11 to maintain the scraper in a first assembled state. Specifically, the shape of the first receiving groove 22 is approximately the same as the shape of the end of the scraper body 1 on which the first blade 31 is mounted. The first receiving groove 22, sleeved on the end of the scraper body 1, restricts the width of the scraper component 2. The snap fastener 21 is specifically U-shaped. By squeezing the buckles 21 from both sides, the spacing of their hooks can be changed, allowing the buckles 21 to disengage from or be inserted into the sockets 11. The connection between the buckles 21 and the sockets 11 can be based on the principle of a snap fastener. During the fitting process of the first receiving groove 22, the buckles 21 must be aligned with the sockets 11 and inserted. The snap-fit ​​between the buckles 21 and the sockets 11 restricts the pushing direction of the scraper component 2 and the scraper body 1, thereby improving the stability of their connection. When it is necessary to switch back to the original working state, squeezing the hooks of the buckles 21 will disengage them from the sockets 11, thereby removing the scraper component 2 from the scraper body 1.

[0118] Reference Figure 23 , Figure 24 , Figure 25 , Figure 26 and Figure 27 In some embodiments, the scraper body 1 includes a guide hole 12, and the scraper component 2 includes a guide post 23. The guide hole 12 extends along the length direction of the scraper body 1 and includes a first end 121 and a second end 122 that are far apart from each other. The first end 121 is located away from the first blade 31. The guide post 23 can slide along the length direction of the guide hole 12 and can rotate relative to the guide hole 12. Specifically, the guide post 23 has a T-shaped column structure, and the guide hole 12 has a stepped hole structure that mates with the guide post 23. After the guide post 23 is assembled into the guide hole 12, the guide post 23 cannot detach from the guide hole 12 along its axial direction. When the scraper is in its original working state, that is, when the first blade 31 is in the usable state, the guide post 23 is placed at the first end 121 of the guide hole 12, and the scraper component 2 and the second blade 32 are housed in the scraper body 1. When the scraper is in the first assembly state, that is, when the second blade 32 is in the usable state, the guide post 23 is placed at the second end 122 of the guide hole 12, and the scraper component 2 and the second blade 32 extend out of the scraper body 1.

[0119] The guide post 23 is movably connected to the guide hole 12, allowing the scraper component 2 to slide along the length direction of the guide hole 12 and rotate relative to the scraper body 1. For example, when the guide post 23 is placed at the second end 122 of the guide hole 12, the width direction of the second blade 32 is approximately perpendicular to the length direction of the scraper body 1, so that when the user holds the scraper body 1, the blade of the second blade 32 extends from the length direction of the scraper body 1, making it convenient for the second blade 32 to work. Conversely, since the length and width dimensions of the scraper body 1 are larger than those of the scraper component 2, when the second blade 32 is not needed, when the guide post 23 is at the second end 122 or sliding from the second end 122 to the first end 121, the scraper component 2 is rotated so that its width direction is approximately parallel to the width direction of the scraper body 1, and then the guide post 23 is pushed to the first end 121 of the guide hole 12, so that the scraper component 2 is housed on the scraper body 1, and the scraper component 2 and its second blade 32 do not extend from the length direction of the scraper body 1.

[0120] The scraper body 1 is also provided with an elastic arm and a limiting boss 13 disposed on the elastic arm. When the scraper is in the first assembled state and the second blade is in the usable state, the limiting boss 13 abuts against the end wall of the scraper component 2 away from the second blade 32 to restrict the rotation and sliding of the guide post 23. Specifically, the limiting boss 13 has a limiting wall 130 and a guide wall 131, wherein the guide wall 131 is inclined toward the first end 121 of the guide hole 12, and the limiting wall 130 is perpendicular to the outer wall surface of the scraper body 1. When the scraper is in the first assembled state, the limiting wall 130 abuts against the scraper component 2, so that the second blade 32 is kept in the usable state, so that the second blade 32 can be used for cleaning work. And when the scraper component 2 is in the first end 121 of the guide hole 12, the second blade 32 The distance extending beyond the scraper body 1 is greater than the distance extending beyond the scraper body 1 of the first blade 31, ensuring that only the second blade 32 can be used for operation, thus preventing the first blade 31 from extending too far and interfering with the operation of the second blade 32. Furthermore, the inclined guide wall 131 allows the scraper component 2 to press against the limiting boss 13 with its outer wall when sliding from the first end 121 to the second end 122 of the guide hole 12, forcing it to move out of position. To improve the stability of the scraper component 2 in the corresponding position when the scraper is in the first assembled state, two limiting bosses 13 can be provided, symmetrically distributed on both sides of the guide hole 12. Switching the scraper from the first assembled state to the original working state requires a case-by-case discussion based on the design of the guide hole 12.

[0121] like Figure 23 , Figure 24 and Figure 25As shown, the guide hole 12 is a straight strip-shaped hole, and the guide hole 12 is distributed along the central axis of the scraper body 1. The guide post 23 can rotate relative to the guide hole 12 and slide along the length direction of the guide hole 12. When the scraper is in the first assembly state, the scraper component 2 is restricted by the limiting wall 130 and cannot rotate, and remains in the use state. By pressing the limiting boss 13, the limiting wall 130 is released from the restriction on the end wall of the scraper component 2. By rotating the scraper component 2, its width direction is made to be approximately parallel to the length direction of the scraper body 1. At this time, the scraper component 2 is slid from the second end 122 of the guide hole 12 to the first end 121 until the guide post 23 is placed at the first end 121 of the guide hole 12, that is, the scraper switches to the original working state. In order to keep the scraper in its original working state, a second receiving groove 14 can be provided at the end of the scraper body 1 away from the first blade 31. When the scraper is in its original working state, that is, when the first blade 31 is in a usable state, the scraper component 2 and the second blade 32 are received in the second receiving groove 14.

[0122] like Figure 26 and Figure 27 As shown, at least two guide holes 12 and guide posts 23 are provided. The at least two guide holes 12 are concentric arc-shaped holes with different radii. The at least two guide posts 23 can rotate and slide synchronously along the arc trajectory of the corresponding guide holes 12. Through the cooperation of multiple guide posts 23 with multiple arc-shaped guide holes 12, the scraper component 2 can rotate to switch the second blade 32 to a usable or unusable state, thereby improving the connection stability between the scraper component 2 and the scraper body 1. Figure 26 When the scraper is in the first assembly state, the scraper component 2 is restricted by the limiting wall 130 and cannot swing along the length direction of the guide hole 12, thus remaining in the working state. By pressing the limiting boss 13, the limiting wall 130 is released from the restriction on the end wall of the scraper component 2. At this time, the guide post 23 can slide from the second end 122 to the first end 121 along the length direction of the guide hole 12. That is, the scraper component 2 can swing from its width direction perpendicular to the length direction of the scraper body 1 to being approximately parallel to it, i.e., the scraper switches to the original working state. When the scraper component 2 is approximately parallel to the length direction of the scraper body 1 in its width direction, the scraper component 2 will press down the limiting boss 13, so that the limiting boss 13 always abuts against the outer wall of the scraper component 2 where the guide post 23 is located, and the end of the guide post 23 in the guide hole 12 is fastened to the guide hole 12 along its axial direction. Thus, the scraper component 2 is stably held in a position where its width direction is approximately parallel to the length direction of the scraper body 1, i.e., the scraper is stably held in the original working state.

[0123] The following are further examples combining the above content:

[0124] like Figures 1-14The first embodiment shown in this embodiment includes a scraper body 1 and a scraper component 2. The scraper body 1 is provided with a first blade 31; the scraper component 2 is provided with a second blade 32. The width of the second blade 32 is not equal to that of the first blade 31. In this embodiment, the width of the second blade 32 is greater than the width of the first blade 31, and the second blade 32 is composed of two first blades 31 arranged side by side. Specifically, an installation structure 5 with a width approximately the same as that of the first blade 31 is provided on the bottom surface 100 of the connecting end 10 of the scraper body 1 to facilitate fixing the first blade 31 to the scraper body 1. An installation structure 5 with a width approximately the same as that of the first blade 31 is provided on the scraper component 2. A mounting structure 5, with approximately the same width when placed side-by-side, is used to fix a second blade 32, twice the width of the first blade 31, onto the scraper component 2. When the scraper component 2 is detached from the scraper body 1, the scraper is in its original working state, the first blade 31 is usable, and the second blade 32 is unusable. When the scraper component 2 is assembled onto the scraper body 1, the scraper has a first assembly state, a second assembly state, and a third assembly state, and the second blade 32 is usable. Specifically, the scraper body 1 includes a connecting end 10, and the scraper component 2 is provided with a connecting cavity 20, which includes a first cavity 201 and a second cavity 20. 2. An opening 200 is provided on one side of the first cavity 201. Through the opening 200, the connecting end 10, on which the first blade 31 is mounted, can be inserted into the connecting cavity 20, so that the first blade 31 is placed in the second cavity 202. The connecting end 10 is locked in the first cavity 201, and the connecting end 10 is not easily disengaged from the connecting cavity 20 through the opening 200 due to the locking of the first limiting protrusion 102 and the first limiting hole 205. This keeps the scraper in the first assembled state, and the wider second blade 32 can be used for cleaning. Conversely, after the scraper component 2 is removed from the connecting end 10, the first blade 31 is exposed, and the scraper is switched to its original position. In the initial working state, the first blade 31 with a smaller width can be used for cleaning. In this embodiment, a second limiting hole 206 is also provided on the top wall 204 of the connecting cavity 20, which is offset from the first limiting hole 205 in the second direction D2. The scraper component 2 is inserted through the connecting end 10 from the first limiting hole 205 to the second limiting hole 206, so that the scraper can have a second assembly state and a third assembly state. When the scraper is in the second assembly state and the third assembly state, the second blade 32 on the scraper component 2 has a different angle with the scraper body 1, so that the scraper in these two states can perform cleaning work on the inclined plane.

[0125] like Figure 4 When the scraper is in its original working state, the first blade 31 is in a usable state. At this time, the scraper component 2 can be stored in the user's backpack or placed in a position that does not affect the work.

[0126] like Figure 1When the scraper is in the first assembly state, the second blade 32 is in a usable state. The scraper component 2 is an axial extension of the scraper body 1, and the second blade 32 is generally parallel to the scraper body 1. When the scraper body 1 is held and the scraper is pushed, the first blade 31 is contained in the connecting cavity 20 of the scraper component 2 without being affected or interfering with the second blade 32, and the second blade 32 can smoothly clean the surface that needs to be cleaned.

[0127] like Figure 9 When the scraper is in the second assembly state, the second blade 32 is in a usable state. The connecting end 10 passes through the first limiting hole 205, the connecting cavity 20 and the second limiting hole 206, and the bottom surface 100 of the connecting end 10 faces the scraper component 2. At this time, the second blade 32 and the scraper body 1 form a first included angle α. When the scraper body 1 is held and the scraper is pushed, the first blade 31 is on the side of the scraper component 2 away from the cleaning surface, which does not interfere with the normal operation of the second blade 32. The formation of the first included angle α makes the scraper usable for cleaning inclined surfaces.

[0128] like Figure 12 and Figure 13 When the scraper is in the third assembly state, both the first blade 31 and the second blade 32 are usable. The connecting end 10 passes through the first limiting hole 205, the connecting cavity 20, and the second limiting hole 206, with the top surface 101 of the connecting end 10 facing the scraper component 2. At this time, the second blade 32 forms a second included angle β with the scraper body 1. The user can choose as follows: Figure 12 Hold the scraper body 1 in the direction shown, so that the wider second blade 32 faces the cleaning surface. In this position, the first blade 31 is on the side of the scraper component 2 furthest from the cleaning surface, without affecting the use of the second blade 32. Conversely, the user can also choose as follows: Figure 13 Hold the scraper body 1 in the direction shown, so that the narrower first blade 31 faces the cleaning surface. At this time, the scraper component 2 is on the side of the scraper body 1 away from the cleaning surface, which does not affect the use of the first blade 31.

[0129] like Figure 6 and Figure 7 As shown in Embodiment 2, Embodiment 2 of this utility model also proposes an accessory for a scraper. The accessory includes a scraper component 2 and a second blade 32 disposed on the scraper component 2. The scraper component 2 provided in this embodiment has the same structure as the scraper component 2 in Embodiment 1. In practical applications, when a user has a scraper body 1 as described in Embodiment 1 or a scraper similar to the scraper body 1, they can purchase the accessory of this embodiment separately and assemble it on the corresponding scraper to expand the ways of using the scraper.

[0130] like Figure 15The scraper shown in Embodiment 3 is largely the same as the scraper in Embodiment 1 above. The similarities will not be repeated here. The main difference is that the scraper does not have the first limiting hole 205 and the second limiting hole 206. That is, the scraper only has the original working state and the first assembly state. In addition, the connecting cavity 20 in this embodiment is also provided with a side opening 207. The side opening 207 allows the scraper component 2 to be installed on or removed from the connecting end 10 of the scraper body 1 more quickly.

[0131] like Figure 16 The fourth embodiment shown is largely the same as the scraper in the first embodiment, and the similarities will not be repeated here. The main difference is that the scraper does not have the first limiting hole 205 and the second limiting hole 206, that is, the scraper only has the original working state and the first assembly state. In addition, this embodiment uses two elastic buckles 105 arranged side by side on the top surface 101 of the connecting end 10, and two corresponding locking through holes 208 are opened on the top wall 204 of the connecting cavity 20. The scraper can be kept in the first assembly state by the engagement of the elastic buckles 105 and the locking through holes 208.

[0132] like Figure 17 The fifth embodiment shown is largely the same as the scraper in the fourth embodiment, and the similarities will not be repeated here. The main difference is that in this embodiment, two elastic buckles 105 are distributed on the two opposite outer walls of the connecting end 10, and clamping through holes 208 are opened on the two opposite side walls of the connecting cavity 20. The scraper can be kept in the first assembly state by the engagement of the elastic buckles 105 with the clamping through holes 208.

[0133] like Figure 18 The scraper shown in Embodiment Six is ​​largely the same as the scraper in Embodiment One, and the similarities will not be repeated here. The main difference is that the scraper does not have the first limiting hole 205 and the second limiting hole 206, that is, the scraper only has the original working state and the first assembly state. In addition, in this embodiment, an annular groove 107 is provided on the outer wall of the connecting end 10, and an annular protrusion 209 is provided on the inner wall of the connecting cavity 20 to engage with the annular groove 107. The scraper is kept in the first assembly state by engaging the annular protrusion 107 with the annular groove 209.

[0134] like Figure 19The scraper shown in Embodiment Seven is largely the same as the scraper in Embodiment One, and the similarities will not be repeated here. The main difference is that the scraper does not have the first limiting hole 205 and the second limiting hole 206, that is, the scraper only has the original working state and the first assembly state. In addition, in this embodiment, two limiting screw holes 106 are opened on the top surface 101 of the connecting end 10. After the connecting end 10 is inserted into the connecting cavity 20, the two limiting bolts 400 are threaded through the top wall 204 of the connecting cavity 20 and connected to the two limiting screw holes 106 one by one, so that the scraper is kept in the first assembly state.

[0135] like Figure 20 and Figure 21 The scraper shown in Embodiment 8 is largely the same as the scraper in Embodiment 1, and the similarities will not be repeated here. The main difference is that the scraper does not have the first limiting hole 205 and the second limiting hole 206, that is, the scraper only has the original working state and the first assembly state. In addition, the top wall 204 of the connecting cavity 20 in this embodiment is removed to form an open cavity, and a magnetic element 401 is installed on the bottom wall 203 of the connecting cavity 20, and another magnetic element 401 is installed on the bottom surface 100 of the connecting end 10. The magnetic attraction of the two magnetic elements 401 makes it difficult for the scraper component 2 to detach from the scraper body 1 in its thickness direction. In addition, an L-shaped hook 15 can be provided on the bottom surface 100 of the connecting end 10. When the scraper is in the first assembly state, the L-shaped hook 15 is engaged with the bottom wall 203 of the connecting cavity 20, which further improves the connection stability of the scraper component 2 and the scraper body 1 in its thickness direction.

[0136] like Figure 22 The scraper shown in Embodiment Nine is largely the same as that in Embodiment One, and the similarities will not be repeated here. The main difference is that the scraper does not have a connecting cavity 20, a first limiting hole 205, and a second limiting hole 206. That is, the scraper only has an original working state and a first assembly state. In addition, this embodiment provides a buckle 21 on the scraper component 2 and a insertion hole 11 on the scraper body 1. The scraper is kept in the first assembly state by the snap-fit ​​between the buckle 21 and the insertion hole 11. A first receiving groove 22 is also provided on the scraper component 2, so that the end of the scraper body 1 is embedded in the first receiving groove 22 and the first blade 31 can be received in the first receiving groove 22. This can improve the connection stability between the scraper body 1 and the scraper component 2, and also ensure that the first blade 31 is received when the scraper is in the first assembly state.

[0137] like Figure 23 , Figure 24 and Figure 25The tenth embodiment shown is largely the same as the scraper in the first embodiment, and the similarities will not be repeated here. The main difference is that the scraper does not have a connecting cavity 20, a first limiting hole 205, and a second limiting hole 206. That is, the scraper only has an original working state and a first assembly state. In this embodiment, a straight, strip-shaped guide hole 12 is provided on the scraper body 1, and a guide post 23 that cooperates with the guide hole 12 is provided on the scraper component 2. When the scraper is in the first assembly state, the scraper component 2 is located at the end of the scraper body 1 where the first blade 31 is located, and the scraper component 2 is subjected to... The limiting boss 13 keeps the width direction of the scraper body 1 approximately perpendicular to its length direction. At this time, the distance that the second blade 32 on the scraper component 2 extends out of the scraper body 1 is greater than the distance that the first blade 31 extends out of the scraper body 1. The second blade 32 is used for cleaning. When it is necessary to switch back to the original working state, press the limiting boss 13 so that the scraper component 2 can rotate to a state where its width direction is parallel to the length direction of the scraper body 1. Then slide the scraper component 2 into the second receiving groove 14. At this time, the scraper component 2 and its second blade 32 are received, and the first blade 31 is exposed for work.

[0138] like Figure 26 and Figure 27 The scraper shown in Embodiment Eleven is largely the same as the scraper in Embodiment Ten, and the similarities will not be repeated here. The main difference is that the guide hole 12 in this embodiment is an arc-shaped hole, and there are two guide holes 12, which are concentrically distributed to improve the connection stability between the scraper body 1 and the scraper component 2. The scraper component 2 can slide along the length direction of the guide hole 12. When the scraper component 2 is at the first end 121 of the guide hole 12, the scraper is in its original working state. The scraper component 2 is restricted by the limiting boss 13 and the guide post 23 and is kept in a position where its width direction is approximately parallel to the length direction of the scraper body 1. When the scraper component 2 is at the second end 122 of the guide hole 12, the second blade 32 on the scraper component 2 is exposed outside the scraper body 1, and the scraper is in the first assembly state. The scraper component 2 is restricted by the limiting wall 130 of the limiting boss 13 and is kept in a position where its width direction is approximately perpendicular to the length direction of the scraper body 1.
