It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0062] 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.
[0063] See attached document Figure 1 -Appendix Figure 24 This utility model proposes a crevice brush, which includes a first brush and a second brush. The first brush includes a first handle 1 and a first brush head 3 connected to the first handle 1, and the second brush includes a second handle 2 and a second brush head 4 connected to the second handle 2. The first handle 1 and the second handle 2 are detachably connected. Specifically, both the first brush head 3 and the second brush head 4 are equipped with one or more rows of bristles, which clean the crevices. The first brush head 3 is connected to the end of the first handle 1, and the second brush head 4 is connected to the end of the second handle 2, so that the user can use it by holding either the first handle 1 or the second handle 2. The first handle 1 and the second handle 2 can be detachably connected by bolts, buckles, clips, or snap-fits. This detachable connection allows the first handle 1 and the second handle 2 to be used as a single crevice tool or to be disassembled into two separate crevice tools. When the first handle 1 and the second handle 2 are connected, the bristles on the first brush head 3 and the bristles on the second brush head 4 can be used for crevice cleaning. Alternatively, when the first handle 1 and the second handle 2 are not connected, the user can choose to use the first brush head 3 or the second brush head 4 as needed or use them alternately. In summary, when using this crevice tool, the user can choose to use it as a single tool or multiple tools, and there is no need to frequently clean or replace the bristles on the first brush head 3 or the second brush head 4, thereby improving the user experience.
[0064] Reference Figure 1 , Figure 2 , Figure 7 and Figure 12 In some embodiments, when the first handle 1 is connected to the second handle 2, the first brush head 3 and the second brush head 4 are arranged opposite to each other, that is, the first brush head 3 and the second brush head 4 can be distributed at the same end, and the bristles on the first brush head 3 and the second brush head 4 both face outward, so that the first brush head 3 and the second brush head 4 on the same side can be used for cleaning gaps; in some embodiments, the first brush head 3 and the second brush head 4 can also be distributed at both ends. In this case, the first handle 1 and the second handle 2 are connected in the middle to form a handle for the user to hold, and the user can choose the first brush head 3 or the second brush head 4 to clean gaps as needed.
[0065] Reference Figure 4 In some embodiments, the first handle 1 is provided with a receiving cavity 10 extending along its length direction, and the end of the receiving cavity 10 is provided with an opening 100. At least part of the second handle 2 is inserted into the receiving cavity 10 through the opening 100. Specifically, the first handle 1 and the second handle 2 are both flat rod-shaped structures, and the receiving cavity 10 is correspondingly set as a square cavity. By inserting the second handle 2 into the receiving cavity 10, the crevice brush can be assembled into one for use. Conversely, by pulling the second handle 2 out of the receiving cavity 10, the crevice brush can be divided into two for use.
[0066] Reference Figure 4The inner wall of the receiving cavity 10 is provided with at least one locking protrusion 101, which extends along the length of the receiving cavity 10. When the second handle 2 is inserted into the receiving cavity 10, the locking protrusion 101 forms an interference fit with the outer wall of the second handle 2 to prevent the second handle 2 from disengaging from the receiving cavity 10. Specifically, the first handle 1 and the second handle 2 can be made of plastic, giving them a certain degree of deformation capability. The thickness of the locking protrusion 101 is approximately the same as the thickness of the second handle 2, allowing the surface of the locking protrusion 101 to have a larger contact area with the second handle 2. The handle 2 contacts the side wall, thereby improving the stability of the second handle 2 within the receiving cavity 10. Furthermore, two clamping protrusions 101 can be provided, symmetrically distributed on opposite inner walls of the receiving cavity 10, simultaneously clamping and securing the second handle 2 inserted into the receiving cavity 10. Additionally, the end of the clamping protrusion 101 near the opening 100 of the receiving cavity 10 is rounded to allow the second handle 2 to smoothly insert between the two clamping protrusions 101 after entering the receiving cavity 100 through the opening 100, improving the user experience. When the crevice brush needs to be used separately, the user can pull the second handle 2 away from the opening 100, overcoming the force of the two clamping protrusions 101 to detach the second handle 2 from the receiving cavity 10. Furthermore, the thickness of the second handle 2 is approximately the same as the thickness of the receiving cavity 10, preventing the second handle 2 from wobbling along the thickness direction while inserted into the receiving cavity 10, thus improving the stability of the crevice brush during use.
[0067] To further prevent the second handle 2 from detaching from the receiving cavity 10, a locking structure such as a buckle or screw can be provided between the first handle 1 and the second handle 2, such as... Figure 3 As shown, in some embodiments, the outer wall of the second handle 2 is provided with an elastic buckle 200; the side wall of the receiving cavity 10 is provided with a locking through hole 102 communicating with the outside. Specifically, the locking through hole 102 is distributed in the receiving cavity 10 near the opening 100, which is one end of the first brush head 3 and the second brush head 4, catering to the user's usage habits, so that the user can operate the elastic buckle 200 locked in the locking through hole 102; when the second handle 2 is inserted into the receiving cavity 10 to the preset position, the elastic buckle 200 elastically locks into the locking through hole 102 to prevent the second handle 2 from detaching from the receiving cavity 10; by pressing the elastic buckle 200 to disengage it from the locking through hole 102, the second handle 2 can be separated from the receiving cavity 10. Anti-slip texture and other structures can also be provided on the top surface of the elastic buckle 200 to facilitate user use.
[0068] Reference Figure 6In some embodiments, the receiving cavity 10 is provided with a threaded hole 104, and the second handle 2 is provided with a threaded part 203 that is threadedly connected to the threaded hole 104. When the second handle 2 is inserted into the receiving cavity 10, the threaded part 203 is connected to the threaded hole 104. Specifically, the receiving cavity 10 is a cylindrical cavity, and the thread of the threaded hole 104 is formed on the inner wall of the receiving cavity 10. The second handle 2 is correspondingly set as a round rod, and the threaded part 203 is provided on the outer wall of the round rod. The second handle 2 is assembled on the first handle 1 by the threaded connection between the threaded part 203 and the threaded hole 104. Conversely, the gap brush can be used separately by disconnecting the connection between the two.
[0069] Reference Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 14 In some embodiments, the outer wall of the first handle 1 is provided with a first slot 11 extending along its length; at least a portion of the second handle 2 is engaged in the first slot 11. Specifically, the first slot 11 can be configured to be open at both ends or closed at both ends. The open-ended first slot 11 facilitates the second handle 2 being engaged in the first slot 11, while the closed-ended first slot 11 helps prevent axial movement of the second handle 2, thus improving stability. In addition, the second handle 2 can be engaged with all or part of its structure with the first slot 11, so that the first handle 1 and the second handle 2 can be assembled, allowing the slit brush to be used as one. Conversely, by removing the second handle 2 from the first slot 11, the slit brush can be used as two. It should also be noted that the number of first slots 11 can be set, and magnetic connections or locking protrusion structures can be provided between the first handle 1 and the second handle 2 to improve the connection stability between the first handle 1 and the second handle 2. Furthermore, the connection between the first handle 1 and the second handle 2 can also be achieved through a hinged and snap-fit method, a multi-rod interlocking method, or a flexible buckle 5, for example. Figure 17 , Figure 15 , Figure 16 The example shown.
[0070] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4In some embodiments, the first brush head 3 includes a first support rod 31 and at least one row of first bristles 32 disposed on the first support rod 31; the second brush head 4 includes a second support rod 41 and at least one row of second bristles 42 disposed on the second support rod 41; when the first handle 1 is connected to the second handle 2, the orientation of the first bristles 32 is opposite to that of the second bristles 42. The first bristles 32 are arranged along the length direction of the first support rod 31 to form a flat first brush head 3, and the structure of the second brush head 4 is similar; as shown... Figure 4 The first support rod 31 includes a first main rod 312 and a first bent rod 313 extending and bending from the end of the first main rod 312. The first bristles 32 are distributed on the first main rod 312 and the first bent rod 313. The second support rod 41 includes a second main rod 412 and a second bent rod 413 extending and bending from the end of the second main rod 412. The second bristles 42 are distributed on the second main rod 412 and the second bent rod 413. The first bent rod 313 and the second bent rod 413 are designed so that when the user inserts the first bent rod 313 or the second bent rod 413 into the gap at a certain angle for cleaning, the first bristles 32 on the first bent rod 313 or the second bristles 42 on the second bent rod 413 can clean the gap without the user having to keep the first handle 1 horizontal with the gap, thereby improving the user experience.
[0071] Reference Figure 4In some embodiments, the first support rod 31 includes a first connecting end 310 and a first external end 311 that are far apart from each other, and the first connecting end 310 is connected to the first handle 1; the second support rod 41 includes a second connecting end 410 and a second external end 411, and the second connecting end 410 is connected to the second handle 2; when the first handle 1 and the second handle 2 are connected, the first external end 311 and the second external end 411 can be connected to each other. Specifically, both the first handle 1 and the second handle 2 are provided with connecting holes 18, which extend along the length direction of the first handle 1 or the second handle 2. The first connecting end 310 is inserted into the connecting hole 18 of the first handle 1, and the second connecting end 410 is inserted into the connecting hole 18 of the second handle 2. The first connecting end 310 or the second connecting end 410 and the connecting hole 18 are interference-fitted, so that the first support rod 31 or the second support rod 41 inserted into the connecting hole 18 is not easy to fall out; in order to improve the stability of the first brush head 3 and the second brush head 4 during use, the first handle After being connected to the second handle 2, the first external end 311 and the second external end 411 can be connected to prevent the ends of the first brush head 3 and the second brush head 4 that are far from the handle from shaking or vibrating. In some embodiments, the first external end 311 is distributed at the end of the first bending rod 313 and the second external end 411 is distributed at the end of the second bending rod 413. The bending structure of the first bending rod 313 and the second bending rod 413 can make the first external end 311 and the second external end 411 close to each other, which is beneficial for the connector 6 to connect the two and also beneficial for the miniaturization of the connector 6 and the reduction of production costs.
[0072] Reference Figure 5 In some embodiments, the crevice brush further includes a connector 6, which has two symmetrical fourth slots 60. The first external end 311 and the second external end 411 are respectively engaged in the two fourth slots 60. The connector 6 connects the first external end 311 and the second external end 411, improving the stability when the first brush head 3 and the second brush head 4 are used together. The engagement method of the two fourth slots 60 with the first external end 311 and the second external end 411 is beneficial for separating and assembling the connector 6 with the first external end 311 and the connector 6 with the second external end 411.
[0073] Furthermore, the connector 6 can be directly fixed to either the first external end 311 or the second external end 411, while the other can be connected to the first external end 311 and the second external end 411 by engaging with the fourth slot 60 on the connector 6 or by making the connector 6 into a U-shaped clamping member, as specifically as follows: Figure 18 , Figure 19 , Figure 21 and Figure 23 The example shown.
[0074] The following are further examples combining the above content:
[0075] like Figures 1-5 The first embodiment shown in this embodiment includes a first handle 1 and a second handle 2. The first handle 1 has a receiving cavity 10, and the receiving cavity 10 has two opposing locking protrusions 101. The thickness of the second handle 2 is approximately the same as the thickness of the receiving cavity 10. In this embodiment, to prevent the second handle 2 from being excessively inserted into the receiving cavity 10, a limiting part 201 is provided at the end of the second handle 2 near the second brush head 4. The radial dimension of the limiting part 201 is larger than the radial dimension of the opening 100 of the receiving cavity 10. Specifically, in this embodiment, the width and length of the limiting part 201 are both larger than the width and length of the opening 100. By the limiting part 201 abutting against the end wall of the end of the first handle 1 with the opening 100, the insertion of the second handle 2 into the receiving cavity 10 is limited, preventing the end of the second handle 2 away from the second brush head 4 from interfering with the receiving cavity 100. The bottom wall of handle 0 abuts against the second handle 2, causing it to break. Additionally, this embodiment provides a first external through hole 103 extending along its thickness direction at the end of the first handle 1 away from the opening 100, and correspondingly, a second external through hole 202 is provided on the second handle 2. When the second handle 2 is inserted into a preset position within the receiving cavity 10, the second external through hole 202 aligns with the first external through hole 103, allowing the first handle 1 and the second handle 2 to be assembled into a single crevice tool, which can then be hung in a designated position. Separated crevice tools can also be hung in a designated position through their corresponding external through holes. In summary, the first external through hole 103 or the second external through hole 202 can be used to connect a hanging rope, or the crevice tool can be directly hung on a hook or similar location on a wall for easy carrying and storage. Figure 4 and Figure 5 In this embodiment, the connector 6 includes two symmetrically arranged fourth slots 60. The first external end 311 on the first brush head 3 is inserted into one fourth slot 60, and the second external end 411 on the second brush head 4 is inserted into the other fourth slot 60, thereby connecting the first external end 311 and the second external end 411 to maintain the stability of the first brush head 3 and the second brush head 4 at the tail.
[0076] like Figure 6The second embodiment shown is largely the same as the crevice brush in the first embodiment, and the similarities will not be repeated here. The main difference lies in the housing cavity 10 of the crevice brush in this embodiment. Specifically, the housing cavity 10 is provided with a threaded hole 104, and the second handle 2 is provided with a threaded part 203 that is threadedly connected to the threaded hole 104. When the second handle 2 is inserted into the housing cavity 10, the threaded part 203 connects with the threaded hole 104. The housing cavity 10 is a circular hole, and the threaded hole 104 is coaxially arranged with the housing cavity 10. The second handle 2 is located at the end of the receiving cavity 10 away from the opening 100. The second handle 2 is a round rod structure. The outer wall of the end away from the second brush head 4 is provided with a threaded part 203. By inserting the second handle 2 into the receiving cavity 10 and rotating the second handle 2 so that its threaded part 203 is threadedly connected to the threaded hole 104, the second handle 2 and the first handle 1 can be assembled into a single crevice tool for use. Conversely, by rotating the second handle 2 to release the connection between the threaded part 203 and the threaded hole 104, the second handle 2 can be removed from the receiving cavity 10, so that the crevice tool can be used in two parts.
[0077] like Figure 7 and Figure 8 The third embodiment shown is roughly the same as the crevice brush in the first embodiment. The similarities will not be repeated here. The main difference is that the connection method between the first handle 1 and the second handle 2 in this embodiment is different from that in the first embodiment. Specifically, the outer wall of the first handle 1 is provided with a first groove 11 extending along its length direction; at least part of the second handle 2 is engaged in the first groove 11. Specifically, the first slot 11 is provided with at least one second slot 12, and the second handle 2 is provided with at least one second protrusion 22 that can engage with the second slot 12. When the second handle 2 is engaged in the first slot 11, the second protrusion 22 engages with the second slot 12. In this embodiment, there are two second protrusions 22 and two slots 12, and the depth direction of the second slot 12 is perpendicular to the length direction of the first slot 11. That is, the engagement of the second handle 2 with the first slot 11 restricts the movement of the second handle 2 along its width direction, while the engagement of the second protrusion 22 with the second slot 12 further enhances the connection stability between the first handle 1 and the second handle 2, thereby restricting the movement of the second handle 2 along its length direction.
[0078] like Figure 9The fourth embodiment shown is largely the same as the crevice brush in the third embodiment described above. The similarities will not be repeated here. The main difference is that the second slot 12 is not provided in the first slot 11 of this embodiment, and the second handle 2 is not provided with the second protrusion 22. Specifically, the first magnetic element 13 is provided in the first slot 11, and the second handle 2 is provided with the second magnetic element 23. When the second handle 2 is engaged in the first slot 11, the first magnetic element 13 and the second magnetic element 23 are magnetically attracted and fixed. That is, by embedding the first magnetic element 13 in the first slot 11 and embedding the second magnetic element 23 in the outer wall of the second handle 2, the first magnetic element 13 and the second magnetic element 23 can be sheet magnets. When the side of the second handle 2 with the second magnetic element 23 is engaged in the first slot 11, the second magnetic element 23 and the first magnetic element 13 are magnetically attracted to each other, thereby further fixing the first handle 1 and the second handle 2.
[0079] like Figure 10 The fifth embodiment shown is largely the same as the crevice brush in the third embodiment, and the similarities will not be repeated here. The main difference lies in the structure of the first slot 11 in this embodiment, which differs from that in the third embodiment. Specifically, the first slot 11 in this embodiment is a T-slot 110, and the second handle 2 is provided with a T-shaped platform 210 that mates with the T-slot 110. That is, this embodiment uses a sliding rail connection method, and the first handle 1 and the second handle 2 are assembled through the connection between the T-shaped platform 210 and the T-slot 110. In order to prevent the second handle 2 from detaching from the first handle 1 along the length direction, a limiting protrusion 2100 can be provided at the end of the T-shaped platform 210 away from the second brush head 4, and a notch is opened at the corresponding position of the T-slot 110 to form a limiting wall 1100. Through the abutment between the limiting protrusion 2100 and the limiting wall 1100, the T-shaped platform 210 cannot move along the length direction and detach from the T-slot 110. In addition, in some embodiments, a magnetic connection method, such as in Embodiment 4, can be provided between the T-slot 110 and the T-shaped platform 210 for auxiliary fixation; in some embodiments, the first slot 11 can also be configured as a dovetail slot, and a dovetail platform correspondingly provided on the second handle 2 to cooperate with the dovetail slot.
[0080] like Figure 11 , Figure 12 and Figure 13The sixth embodiment shown is largely the same as the crevice brush in the third embodiment described above. The similarities will not be repeated here. The main difference lies in the structure of the first slot 11 in this embodiment, which differs from that in the third embodiment. The first handle 1 also has a first protrusion 14 extending along its length. The first protrusion 14 and the first slot 11 are respectively formed on two opposite outer walls of the first handle 1. The second handle 2 has a third slot 24 that can engage with the first protrusion 14, and a second protrusion 25 that can engage with the first slot 11. Specifically, the first protrusion 14 extends along the length of the first handle 1, and the second protrusion 25 extends along the length of the second handle 2. Figure 12 The first handle 1 and the second handle 2 are assembled by engaging the second protrusion 25 with the first slot 11. After assembly, the first bristles 32 of the first brush head 3 and the second bristles 42 of the second brush head 4 both face outwards, meaning the first bristles 32 and the second bristles 42 can be used for cleaning crevices. The crevice brush is in working condition. Figure 13 The first handle 1 and the second handle 2 are assembled by engaging the first protrusion 14 with the third slot 24. After assembly, the first bristles 32 of the first brush head 3 and the second bristles 42 of the second brush head 4 are both facing inward, meaning that the first bristles 32 and the second bristles 42 cannot be used for cleaning, and the crevice brush is in a stored state.
[0081] like Figure 14 The crevice brush in Embodiment 7 is largely the same as that in Embodiment 6, and the similarities will not be repeated here. The main difference is that the positions of the first slot 11 and the first protrusion 14 on the first handle 1 and the positions of the third slot 24 and the second protrusion 25 on the second handle 2 are different from those in Embodiment 6. Specifically, the first handle 1 has a first protrusion 14 extending along its length, and the first protrusion 14 and the first slot 11 are located on the same outer wall of the first handle 1; the second handle 2 has a third slot 24 that engages with the first protrusion 14, and a second protrusion 25 that engages with the first slot 11. If the first handle 1 and the second handle 2 in Embodiment 6 are considered to be engaged vertically, then the first handle 1 and the second handle 2 in Embodiment 7 are engaged horizontally. In addition, in this embodiment, the first protrusion 14 and the third slot 24, and the second protrusion 25 and the first slot 11 are engaged simultaneously to connect and assemble the first handle 1 and the second handle 2 together, making the connection between the first handle 1 and the second handle 2 more stable.
[0082] like Figure 15The crevice brush shown in Embodiment 8 is largely the same as the crevice brush in Embodiment 1, and the similarities will not be repeated here. The main difference is that the first handle 1 of this embodiment does not have a receiving cavity 10. Specifically, the first handle 1 has a first limiting hole 15 and a second limiting hole 16 spaced apart, wherein the first limiting hole 15 extends along the length direction of the first handle 1, and the axis of the second limiting hole 16 is perpendicular to the length direction of the first handle 1. The second handle 2 has a first limiting rod 26 that is inserted into the first limiting hole 15 and a second limiting rod 27 that is engaged with the second limiting hole 16. Specifically, the first limiting hole 15 is located on the protrusion at the end of the first handle 1 away from the first brush head 3. On the protrusion, a first limiting hole 15 is formed on the outer wall of the first handle 1, and a second limiting hole 16 is distributed on the outer wall of the first handle 1 near the first brush head 3. The positions of the first limiting rod 26 and the second limiting rod 27 of the second handle 2 are set to correspond to the positions of the first limiting hole 15 and the second limiting hole 16. When assembly is required, the first limiting rod 26 of the second handle 2 is first inserted into the first limiting hole 15, and then the second limiting rod 27 is aligned with the second limiting hole 16 and inserted, so that the second handle 2 fits against the first handle 1. At this time, the width direction of the second handle 2 is limited by the first limiting hole 15, and its length direction is limited by the second limiting hole 16, so that it is stably assembled with the first handle 1.
[0083] like Figure 16The crevice brush 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 first handle 1 of this embodiment does not have a receiving cavity 10. Specifically, the first handle 1 has at least one second slot 12, and the second handle 2 has at least one second protrusion 22 that can engage with the second slot 12. The structure and engagement method of the second protrusion 22 and the second slot 12 are the same as in Embodiment Two, and there are two of each of the second protrusion 22 and the second slot 12. Through the engagement of the second protrusion 22 and the second slot 12, the second handle 2 will not detach from the first handle 1 along its length. To further enhance the connection stability between the second handle 2 and the first handle 1, To prevent the second handle 2 from detaching from the first handle 1 along the width direction, the gap brush in this embodiment also includes at least one elastic buckle 5. When the second latching protrusion 22 engages with the second latching groove 12, the elastic buckle 5 can simultaneously fasten the first handle 1 and the second handle 2 to prevent the first handle 1 and the second handle 2 from detaching along the width direction. Specifically, this embodiment provides two elastic buckles 5, which are spaced apart. The two ends of the bottom of the elastic buckle 5 are rotatably connected to the outer wall of the first handle 1. After the second handle 2 is attached to the first handle 1 and the second latching protrusion 22 engages with the second latching groove 12, by rotating the elastic buckle 5, the end of the elastic buckle 5 away from the rotation center can be fastened to the outer wall of the second handle 2, thereby restricting the width direction of the second handle 2.
[0084] like Figure 17 The crevice brush shown in Embodiment 10 is largely the same as the crevice brush in Embodiment 1, and the similarities will not be repeated here. The main difference is that the first handle 1 of this embodiment does not have a receiving cavity 10. Specifically, the first handle 1 has at least one second slot 12, and the second handle 2 has at least one second protrusion 22 that can engage with the second slot 12. The structure and engagement method of the second protrusion 22 and the second slot 12 are the same as in Embodiment 2, and there is one second protrusion 22 and one second slot 12. The second slot 12 is distributed on the outer wall of the first handle 1 near the first brush head 3. The first handle 1 of this embodiment is away from the first brush head 3. One end of the second handle 2 is rotatably connected to the end of the second handle 2 away from the second brush head 4. When the second brush head 4 can swing around the rotation axis to approach the first brush head 3, the second locking protrusion 22 engages with the second locking groove 12. Specifically, two opposing rotating rings 17 can be set at the end of the first handle 1, and a rotating protrusion 28 rotatably connected to the rotating rings 17 can be set at the end of the second handle 2. A rotating connection relationship is established by inserting the rotating protrusion 28 between the two rotating rings 17. By controlling the second handle 2 to swing around the rotation axis, the end of the second handle 2 with the second locking protrusion 22 approaches the first handle 1, and finally the second locking protrusion 22 engages with the second locking groove 12, thereby connecting and assembling the second handle 2 and the first handle 1.
[0085] like Figure 18 The eleventh embodiment shown is largely the same as the crevice brush in the first embodiment, and the similarities will not be repeated here. The main difference is that the connector 6 of the crevice brush in this embodiment is different from the connector 6 in the first embodiment. Specifically, the connector 6 in this embodiment is fixed to one of the first external end 311 and the second external end 411, and the connector 6 is provided with a fourth slot 60. One of the first external end 311 and the second external end 411 can be engaged with the fourth slot 60. As an example, if the connector 6 is fixed to the first external end 311, then the fourth slot 60 is engaged with the second external end 411. The engagement method between the fourth slot 60 and the second external end 411 is largely the same as in the first embodiment.
[0086] like Figure 19 and Figure 20 The 12th embodiment shown is largely the same as the crevice brush in the first embodiment, and the similarities will not be repeated here. The main difference is that the connector 6 of the crevice brush in this embodiment is different from the connector 6 in the first embodiment. The connector 6 in this embodiment includes two opposing clamping plates 61. One end of the two clamping plates 61 is connected to each other, and the other end is separated to form a clamping end 610. The two clamping ends 610 can approach each other to clamp the first external end 311 and the second external end 411. Specifically, the connector 6 is an elastic structure that allows the two clamping ends 610 to approach each other when no external force is applied. The connector 6 has a U-shaped structure. Due to its elasticity, the two clamping ends 610 approach each other when no external force is applied, and the distance between the two clamping ends 610 is less than the thickness of the first external end 311 (or the second external end 411). In addition, the inner sides of the two clamping plates 61 are provided with anti-slip parts 611. The anti-slip parts 611 can be made of foam cotton, anti-slip rubber, etc. The anti-slip parts 611 increase the friction between the clamping plates 61 and the first external end 311 and the second external end 411, thereby improving the clamping stability of the two clamping plates 61. Based on the above, after the first handle 1 and the second handle 2 are assembled, the connector 6 is put on the first external end 311 and the second external end 411, that is, the first external end 311 and the second external end 411 are clamped simultaneously by the two clamping plates 61.
[0087] like Figure 21 and Figure 22The thirteenth embodiment shown is largely the same as the crevice brush in the twelfth embodiment described above. The similarities will not be repeated here. The main difference is that the connector 6 of the crevice brush in this embodiment is not an elastic structure. Specifically, the crevice brush in this embodiment also includes a locking bolt 7. The locking bolt 7 passes through a clamping plate 61 and is threadedly connected to another clamping plate 61, so that the two clamping ends 610 are close to each other. That is, after the first external end 311 and the second external end 411 are inserted between the two clamping plates 61, the locking bolt 7 forces the two clamping plates 61 to be close to each other, so as to achieve the purpose of simultaneously clamping and connecting the first external end 311 and the second external end 411.
[0088] like Figure 23 and Figure 24 The fourteenth embodiment shown is largely the same as the crevice brush in the twelfth embodiment described above, and the similarities will not be repeated here. The main difference lies in the connector 6 of this embodiment, which differs from that of the twelfth embodiment. Specifically, the connector 6 of this embodiment includes two opposing clamping plates 61, with one end of each clamping plate 61 hinged together and the other end separated to form a clamping end 610. The two clamping ends 610 can approach each other to form a clamping space for clamping the first external end 311 and the second external end 411. The two clamping plates 61 can also be unfolded as follows. Figure 23 The state shown is to facilitate the connection of the first external end 311 and the second external end 411; a clamping plate 61 is provided with a fifth latching protrusion 612, and another clamping plate 61 is provided with a fifth latching groove 613 that engages with the fifth latching protrusion 612. When the two clamping ends 610 approach each other, the fifth latching protrusion 612 engages with the fifth latching groove 613 to maintain clamping space. After the fifth latching protrusion 612 engages with the fifth latching groove 613, the distance between the two clamping plates 61 is approximately the same as the thickness of the first external end 311 (second external end 411), thereby ensuring that the connector 6 can stably connect the first external end 311 and the second external end 411.
