Description

Technical Field

[0001] This disclosure relates to the field of nail art tools, and more particularly to a polishing tool. Background Technology

[0002] In the nail industry, UV-cured gels are extremely common. Once cured, they require filing to be effectively removed. Current nail filing tools rely on manual operation, which can damage nails and makes the process unsafe. Utility Model Content

[0003] This disclosure provides a polishing tool to improve safety during the polishing process, ensuring that even if the polishing head applies significant pressure to the nail surface or tilts, it will not damage the natural nail.

[0004] This disclosure provides a polishing tool, including: a drive member, a polishing head, a base, and a mounting assembly. The polishing head is connected to the drive member and rotates under the drive of the drive member. The base is located at the end of the polishing head away from the drive member, and does not rotate with the polishing head when the polishing head is polishing the workpiece. The mounting assembly is used to rotatably mount the base to the polishing head.

[0005] In some implementations, the base protrudes from the grinding head in the direction of the grinding head's rotation axis.

[0006] In some embodiments, the mounting assembly includes a first mounting part and a second mounting part, which are rotatably connected. The first mounting part is connected to the grinding head, and the second mounting part is connected to the base.

[0007] In some embodiments, the second mounting portion surrounds the outer periphery of the first mounting portion.

[0008] In some embodiments, the grinding head has a mounting opening and a mounting protrusion at one end near the base. The mounting opening is recessed inward in a direction away from the base, and the mounting protrusion is located inside the mounting opening. The size of the mounting opening is determined to accommodate the mounting assembly and the base, and the first mounting portion is mounted on the mounting protrusion.

[0009] In some embodiments, the mounting assembly includes a first part and a second part fixedly connected, the first part extending along the rotation axis of the grinding head, and the second part extending in a direction perpendicular to the extension direction of the first part. The first part is connected to the grinding head, and the second part is rotatably connected to the base.

[0010] In some embodiments, the base includes a first opening and a second opening, wherein the size of the first opening is smaller than the size of the second opening in a direction perpendicular to the rotation axis of the grinding head, the size of the first opening is determined to accommodate the first part, and the size of the second opening is determined to accommodate the second part.

[0011] In some embodiments, the grinding head is provided with a first mounting structure and a second mounting structure at one end near the base. The first part passes through the first opening and the second opening and is fixedly connected to the first mounting structure, and the second mounting structure is adapted to the base.

[0012] In some embodiments, the polishing tool also includes a washer disposed on the surface of the base facing the polishing head.

[0013] In some embodiments, the drive unit includes a drive shaft and a power source. The drive shaft is integrally formed with the grinding head, and the end of the drive shaft away from the grinding head is connected to the power source, which drives the drive shaft to rotate.

[0014] The filing tool disclosed herein employs a mounting component to achieve a rotatable connection between the base and the filing head. The base does not rotate with the filing head during the filing process; for example, when filing UV-cured adhesive on the nail surface, the base can rest against the nail surface. This base design improves safety during filing, preventing damage to the natural nail even if the filing head applies significant pressure or tilts. Furthermore, the mounting component allows for a rotatable connection between the rotating filing head and the stationary base, limiting unnecessary shaking of the filing head during filing.

[0015] It should be understood that the description in this section is not intended to identify key or essential features of the embodiments of this disclosure, nor is it intended to limit the scope of this disclosure. Other features of this disclosure will become readily apparent from the following description. Attached Figure Description

[0024] Figure 8 This is a flowchart illustrating a method for forming a polishing tool according to an embodiment of the present disclosure. Detailed Implementation

[0025] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings. While various detailed descriptions are provided in these embodiments for ease of understanding, those skilled in the art should understand that these embodiments and their detailed descriptions are merely exemplary, and various modifications can be made to these embodiments without departing from the teachings of this disclosure. Similarly, for clarity and brevity, detailed descriptions of well-known functions and structures will be omitted in the following description. Furthermore, embodiments and features described in this disclosure can be combined with each other unless otherwise specified.

[0026] Current nail filing tools rely on manual operation when filing UV-cured gels, making it difficult to guarantee filing precision and easily resulting in uneven filing, which affects the nail art effect. In addition, current nail filing tools lack stability and may wobble during filing, which not only reduces filing efficiency but may also damage the nails.

[0027] Given the current limitations of nail filing tools, which suffer from instability, potential shaking during filing, low filing efficiency, and potential damage to nails, this disclosure provides a new nail filing tool that enhances stability, reduces shaking, and improves filing efficiency and safety.

[0028] This disclosure provides a polishing tool, including a drive unit, a polishing head, a base, and a mounting assembly. The drive unit drives the polishing head to rotate; the polishing head is connected to the drive unit and rotates under its drive. The base is located at the end of the polishing head away from the drive unit and does not rotate with the polishing head while it is polishing the workpiece. The mounting assembly is used to rotatably mount the base to the polishing head.

[0029] It should be noted that the material to be polished can be UV-cured adhesive on the nail surface. Before polishing, a hole can be drilled in a selected location on the nail surface to allow the base 14 and the lower part of the polishing head 13 to extend into the hole during subsequent polishing, thus achieving contact between the base and the nail surface. The outer surface of the polishing head can serve as the polishing surface, which polishes the UV-cured adhesive on the nail surface. Alternatively, before polishing, the polishing surface of the polishing head can be used to polish a selected location of the UV-cured adhesive to expose the nail surface, thus achieving contact between the base and the nail surface during polishing.

[0030] It should be noted that when the grinding head is grinding the UV-cured adhesive on the nail surface, the base does not rotate with the grinding head. The non-rotating base can be rotatably connected to the rotating grinding head through the mounting component. The mounting component can limit unnecessary shaking of the grinding head during the grinding process.

[0031] The filing tool disclosed herein employs a mounting component to achieve a rotatable connection between the base and the filing head. The base does not rotate with the filing head during the filing process. For example, when filing UV-cured adhesive on the nail surface, the base can rest against the nail surface. This base design improves safety during filing, preventing damage to the natural nail even under conditions of high pressure, high rotation speed, vibration, heat, or tilting of the filing head. Furthermore, the mounting component allows for a rotatable connection between the rotating filing head and the stationary base, limiting unnecessary shaking of the filing head during filing.

[0032] like Figures 1 to 6b As shown, the polishing tool provided in this disclosure includes a drive unit, a polishing head 13, a base 14, and a mounting assembly 15. The drive unit drives the polishing head 13 to rotate; the polishing head 13 is connected to the drive unit and rotates under its drive. The base 14 is located at the end of the polishing head 13 away from the drive unit; the base 14 does not rotate with the polishing head 13 when the polishing head 13 is polishing the workpiece. The mounting assembly 15 is used to rotatably mount the base 14 to the polishing head 13.

[0033] In some implementations, such as Figures 1 to 6b As shown, in the direction of the rotation axis of the grinding head 13, the base 14 protrudes from the grinding head 13, that is, in Figure 1In the vertical direction, the base 14 protrudes from the grinding head 13. When grinding the UV-cured adhesive on the nail surface, because the base 14 protrudes from the grinding head 13, the end face of the grinding head 13 near the nail surface will not directly contact the nail surface during the grinding process. This effectively avoids the high-speed rotating grinding head 13 causing chips to the nail surface and also avoids the heat generated by the high-speed rotating grinding head 13 on the nail surface, thereby improving the user's comfort.

[0034] Due to the presence of the base 14, the shape of the grinding head 13 is not limited, and the grinding head 13 can be designed in various shapes. For example, the grinding head 13 can be cylindrical. Along the rotation axis of the grinding head 13 (i.e., along...) Figure 1 (Vertical direction in the image), the cross-sectional shape of the grinding head 13 can also be rectangular. When using the grinding head 13 to grind the UV-cured adhesive on the nail surface, the sharper corners of the grinding head 13 near the nail surface make it easier to cut into the UV-cured adhesive, thereby improving grinding efficiency. In addition, during actual grinding, due to the setting of the base 14, even if the grinding head 13 runs away and drills uncontrollably towards the nail surface, the base 14 can block the grinding head 13, thus preventing the grinding head 13 from damaging the user's nail surface.

[0035] In some implementations, such as Figure 1 As shown, the driving component includes a drive shaft 12 and a power source 11. The drive shaft 12 and the grinding head 13 can be integrally formed. The end of the drive shaft 12 away from the grinding head 13 can be connected to the power source 11, and the power source 11 can drive the drive shaft 12 to rotate. In this disclosure, the rotating grinding head 13 and the non-rotating base 14 are rotatably connected by a mounting assembly 15, which can ensure smooth sliding of the drive shaft 12 during rotation.

[0036] It should be noted that the power source 11 can be a motor. For example, the power source 11 can be a DC servo motor or an AC servo motor.

[0037] For example, the drive shaft 12 can be fixed to a gripper capable of high-speed rotation. The drive shaft 12 can be connected to a motor via the gripper. The grinding head 13 can rotate at high speed under the drive of the motor, and the high-speed rotating grinding head 13 can grind the object to be ground. For example, the grinding surface of the grinding head 13 can grind the UV-cured adhesive on the nail surface.

[0038] It should be noted that the drive shaft 12 and the grinding head 13 can also be manufactured separately, and then welded together by means of welding, for example.

[0039] It should be noted that, in one embodiment, the grinding head 13 may be a solid cylinder. In another embodiment, the grinding head 13 may include two parts, for example, the grinding head 13 includes a first part near the drive shaft 12 and a second part away from the drive shaft 12. The first part may be a hollow structure, and the second part may be a solid structure. That is, the grinding head 13 may not be a completely solid structure; the first part of the grinding head 13 may be a hollow structure, and the second part of the grinding head 13 may be a solid structure.

[0040] In some implementations, such as Figures 1 to 6b As shown, the polishing head 13 has a polishing section, which is spiral in shape. When polishing the UV-cured adhesive on the nail surface with the polishing head 13, the spiral polishing section can more easily cut into the UV-cured adhesive, efficiently remove UV-cured adhesive debris generated during polishing, and closely conform to the curvature of the nail surface, achieving precise polishing of the UV-cured adhesive and effectively removing residual adhesive.

[0041] For example, the upper part of the outer wall side of the grinding head 13 may not be used as a grinding surface, and only the lower part may be used as a grinding surface. In this case, the upper part of the outer wall side of the grinding head 13 can be a smooth surface. Of course, the entire outer wall side of the grinding head 13 can be used as a grinding surface. The grinding surface includes a grinding part, which can be a spiral cutting tooth. The spiral direction of multiple spiral cutting teeth can be the same, and the spacing between adjacent spiral cutting teeth can be the same.

[0042] In some implementations, such as Figure 2 , Figure 3a and Figure 3b As shown, the mounting assembly 15 includes a first mounting part 151 and a second mounting part 152, which are rotatably connected. The first mounting part 151 is connected to the grinding head 13, and the second mounting part 152 is connected to the base 14.

[0043] In some implementations, such as Figure 2 , Figure 3a and Figure 3b As shown, the second mounting portion 152 may surround the outer periphery of the first mounting portion 151. For example, in a plane perpendicular to the rotation axis of the grinding head 13, the cross-sectional shape of the first mounting portion 151 may be circular, and the cross-sectional shape of the second mounting portion 152 may also be circular, and the diameter of the first mounting portion 151 is smaller than the diameter of the second mounting portion 152.

[0044] For example, the mounting component 15 can be a bearing, the first mounting part 151 can be the inner ring of the bearing, and the second mounting part 152 can be the outer ring of the bearing. The inner ring and the outer ring of the bearing are rotatably connected. The outer ring of the bearing can be connected to the base 14, and the inner ring of the bearing can be connected to the grinding head 13. The bearing enables the rotatable connection between the base 14 and the grinding head 13. The inner ring and the outer ring of the bearing are connected by rolling elements (such as balls and rollers) rolling in a raceway, wherein the raceway is the surface on the inner ring and the outer ring of the bearing for the rolling elements to roll.

[0045] In some implementations, such as Figure 2 , Figure 3a and Figure 3b As shown, the grinding head 13 is provided with a mounting port 131 and a mounting protrusion 132 at one end near the base 14. The mounting port 131 is recessed inward toward the direction away from the base 14, and the mounting protrusion 132 is located inside the mounting port 131. The size of the mounting port 131 is determined to accommodate the mounting assembly 15 and the base 14, and the first mounting part 151 is mounted on the mounting protrusion 132.

[0046] For example, the grinding head 13 may be a solid structure, and a hole may be drilled on the end face of the grinding head 13 near the base 14 to form a mounting opening 131, that is, a hole may be drilled on the end face of the grinding head 13 away from the drive shaft 12 to form a mounting opening 131. The size of the hole can be determined according to the size of the mounting assembly 15 and the base 14. For example, in the direction of the rotation axis of the grinding head 13, the size of the mounting opening 131 near the mounting protrusion 132 is smaller than the size away from the mounting protrusion 132, that is, the mounting opening 131 may be a stepped mounting opening. After the mounting protrusion 132 is interference-fitted with the first mounting part 151, in the direction of the rotation axis of the grinding head 13, there may be a certain gap between the second mounting part 152 and the base 14 and the grinding head 13, thereby better ensuring that the second mounting part 152 and the base 14 do not rotate with the grinding head 13.

[0047] For example, when drilling a hole in the end face of the grinding head 13 near the base 14, the drilling force at the middle position of the grinding head 13 can be less than the drilling force at the edge position, thus forming a mounting protrusion 132 at the middle position. For example, the mounting component 15 is a bearing, and the size of the mounting protrusion 132 can be set according to the size of the inner ring of the bearing. The formed mounting protrusion 132 can be adapted to the inner ring of the bearing, so that the inner ring of the bearing can be installed on the mounting protrusion 132.

[0048] For example, the mounting protrusion 132 and the first mounting portion 151 can be connected by welding. In addition, the outer wall of the mounting protrusion 132 can be formed with external threads, and the inner wall of the first mounting portion 151 can be formed with internal threads, so the mounting protrusion 132 and the first mounting portion 151 can be connected by threads.

[0049] For example, the base 14 may include a base connecting portion 141 and a base opening 142. The base connecting portion 141 may be connected to the second mounting portion 152, for example, by welding. Alternatively, the base opening 142 may be interference-fitted with the second mounting portion 152 to achieve connection between the base connecting portion 141 and the second mounting portion 152.

[0050] In some implementations, such as Figure 4 , Figure 5 , Figure 6a and Figure 6b As shown, the mounting assembly 15 includes a first part 151 and a second part 152 fixedly connected. The extension direction of the first part 151 is along the rotation axis of the grinding head 13, that is, the extension direction of the first part 151 is along... Figure 6b In the vertical direction, the extension direction of the second part 152 is perpendicular to the extension direction of the first part 151, that is, the extension direction of the second part 152 is along... Figure 6b The horizontal direction. The first part 151 is connected to the grinding head 13, and the second part 152 is rotatably connected to the base 14. In the direction perpendicular to the rotation axis of the grinding head 13, the size of the first part 151 is smaller than the size of the second part 152, and a step is formed at the connection position of the first part 151 and the second part 152.

[0051] For example, the mounting component 15 may be made of screws, which are fastened to the grinding head 13.

[0052] In some implementations, such as Figure 6b As shown, the base 14 includes a first opening 141 and a second opening 142, in a direction perpendicular to the rotation axis of the grinding head 13 (i.e., Figure 6b (in the horizontal direction), the size of the first opening 141 is smaller than the size of the second opening 142, and the stepped opening formed by the first opening 141 and the second opening 142 is along the extension direction of the grinding head 13 (i.e., along the horizontal direction). Figure 6b The vertical direction) penetrates through the base. The size of the first opening 141 is determined to accommodate the first part 151, and the size of the second opening 142 is determined to accommodate the second part 152, which is rotatably connected to the base 14.

[0053] For example, in a direction perpendicular to the rotation axis of the grinding head 13, the size of the first opening 141 may be slightly larger than the size of the first part 151, and in a direction perpendicular to the rotation axis of the grinding head 13, the size of the second opening 142 may be slightly larger than the size of the second part 152, so that the base 14 and the mounting assembly 15 can be fitted with a gap.

[0054] In some implementations, such as Figure 6b As shown, the grinding head 13 is provided with a first mounting structure 133 and a second mounting structure 134 at one end near the base 14. The first part 151 passes through the first opening 141 and the second opening 142 and is fixedly connected to the first mounting structure 133. The second mounting structure 134 is adapted to the base 14. The base 14 and the grinding head 13 can be assembled with a gap.

[0055] For example, the first mounting structure 133 may be a threaded hole, and the second mounting structure 134 may be a mounting groove surrounding the first mounting structure 133, the mounting groove being recessed in a direction away from the base 14. For example, the first mounting structure 133 and the second mounting structure 134 may be formed by drilling a hole in the end face of the grinding head 13 near the base 14.

[0056] It should be noted that the second mounting structure 134 and the base 14 are compatible, meaning that the base 14 can be installed inside the second mounting structure 134.

[0057] For example, the surface of the first mounting structure 133 may be formed with an internal thread, and the first part 151 may be formed with an external thread, so that the first mounting structure 133 and the first part 151 can be fixedly connected by a threaded connection. After the first mounting structure 133 and the first part 151 are fixedly connected, the base 14 with a stepped opening can abut against the step at the connection position of the first part 151 and the second part 152. In the direction of the rotation axis of the grinding head 13, the second part 152 can prevent the base 14 from falling off.

[0058] It should be noted that the base 14 can be made of a smooth, wear-resistant material, for example, the material of the base 14 can be polytetrafluoroethylene (PTFE).

[0059] For example, during the polishing process, the lower surface of the base 14 abuts against the nail surface, and the upper surface of the base 14 contacts the polishing head 13, which can polish the upper surface of the base 14, making the upper surface of the base 14 smooth. The friction of the upper surface of the base 14 can be less than that of its lower surface, so that the base 14 does not rotate during the polishing process, and the rotating assembly rotates with the polishing head 13.

[0060] In some embodiments, the polishing tool may also include a washer 16, which may be disposed on the surface of the base 14 facing the polishing head 13.

[0061] It should be noted that the washer 16 can be made of a smooth, wear-resistant material, for example, the material of the washer 16 can be PTFE. In a specific embodiment, the material of the washer 16 can be the same as the material of the base 14. Of course, the material of the washer 16 can also be different from the material of the base 14. When the two materials are different, the material of the washer 16 can be a more wear-resistant material with less friction than the material of the base 14.

[0062] For example, the washer 16 can be disposed on the upper surface of the base 14. For example, a smooth PTFE material sheet can be selected, and a through hole is formed in the middle of the sheet. The size of the through hole can be the same as the size of the first opening 141, or the size of the through hole can be slightly larger than the size of the first opening 141. Then, the sheet with the through hole can be fitted onto the base 14. The specific size of the sheet can be set according to the actual design, as long as the sheet can cover part or all of the upper surface of the base 14.

[0063] For example, the base 14 and the grinding head 13 can be fitted with a gap, that is, there can be a certain gap between the side of the base 14 and the grinding head 13. For example, in the extension direction perpendicular to the grinding head 13, the size of the second mounting structure 134 is larger than the size of the base 14. At this time, the side of the base 14 does not contact the grinding head 13, which can improve the smoothness of the rotation of the base 14 and the grinding head 13.

[0064] For example, at the stepped opening position formed by the first opening 141 and the second opening 142, the base 14 forms stepped portions on both sides of the stepped opening, and the second portion 152 abuts against the stepped portion of the base 14. In the direction of the rotation axis of the grinding head 13, the second portion 152 can prevent the base 14 from falling off.

[0065] The polishing tool disclosed herein can be integrated with a robotic arm to achieve automatic polishing, or it can be manually polished by a nail technician operating the polishing tool.

[0066] The object to be polished in this disclosure takes the light-cured adhesive on the nail surface as an example. The specific working process of the polishing tool in this disclosure is explained in detail below.

[0067] Before polishing the UV-cured adhesive 22 on the nail surface 21, a hole can be drilled in the UV-cured adhesive at a selected location on the nail surface so that the base 14 and the lower part of the polishing head 13 can be inserted into the hole during subsequent polishing.

[0068] When the buffing tool is activated to buff the UV-cured adhesive 22 on the nail surface 21, the drive shaft 12 rotates under the drive of the power source 11, which in turn drives the buffing head 13 to rotate. The nail technician or automatic nail equipment brings the buffing tool close to the nail surface and aligns it with the previously drilled holes in the UV-cured adhesive, so that the base 14 and the lower part of the buffing head 13 can press against the nail surface 21. Figure 7 As shown, there is a certain gap between the buffing head 13 and the nail surface 21, allowing the lower part of the buffing head 13 to buff the UV-cured adhesive 22. The non-rotating base 14 is rotatably connected to the buffing head 13 via a mounting assembly. During buffing, the non-rotating base 14 improves safety; even if the buffing head applies significant pressure to the nail surface or tilts, it will not damage the natural nail. Furthermore, the non-rotating base 14 provides stable support for the entire buffing tool, ensuring a smooth buffing process. The mounting assembly also ensures the stability of the drive shaft 12 during rotation. When buffing the UV-cured adhesive 22, the gap between the buffing head 13 and the nail surface 21 reduces the heat generated on the nail surface during high-speed rotation of the buffing head 13, thus improving the customer's comfort. Additionally, the buffing tool of this disclosure reduces the skill requirements for nail technicians and can be integrated with automatic nail buffing machines.

[0069] The following describes the method for forming the polishing tool disclosed herein.

[0070] like Figure 8 As shown, the method for forming the polishing tool in this disclosure may include:

[0071] S101. Install the grinding head onto the drive unit.

[0072] S102. The base is installed on the end of the grinding head away from the drive component using an installation component, so that the base and the grinding head are rotatably connected; wherein, the grinding head rotates under the drive of the drive component, and the base does not rotate with the grinding head when the grinding head is grinding the object to be ground.

[0073] It should be noted that this disclosure does not limit the order of S101 and S102. In actual assembly, S101 can be executed first and then S102, or S102 can be executed first and then S101.

[0074] In some embodiments, a grinding head 13 may be formed, such as Figure 3a and Figure 3bAs shown, the specific process may include: forming a grinding head body, and forming a mounting opening 131 and a mounting protrusion 132 at one end of the grinding head body near the base 14. The mounting opening 131 is recessed inward in a direction away from the base 14, and the mounting protrusion 132 is located inside the mounting opening 131. The specific formation process of the mounting opening 131 and the mounting protrusion 132 has been described above and will not be repeated here.

[0075] In some implementations, an installation component 15 may be formed, such as Figure 3a and Figure 3b As shown, a bearing can be formed, specifically including: forming a first mounting portion 151 and a second mounting portion 152, the first mounting portion 151 and the second mounting portion 152 being rotatably connected. For example, the formed first mounting portion 151 can be the inner ring of the bearing, and the formed second mounting portion 152 can be the outer ring of the bearing.

[0076] In some implementations, such as Figure 3a and Figure 3b As shown, mounting the base 14 to the end of the grinding head 13 away from the drive member using the mounting assembly 15 includes: mounting the first mounting part 151 on the mounting protrusion 132, and placing the second mounting part 152 and the base 14 in the mounting opening 131, and fixing the second mounting part 152 to the base 14. The method of mounting the first mounting part 151 on the mounting protrusion 132 and fixing the second mounting part 152 to the base 14 has been described above and will not be repeated here.

[0077] In some embodiments, a grinding head 13 may be formed, such as Figure 6a and Figure 6b As shown, specifically, it may include: forming a grinding head body, and forming a first mounting structure 133 and a second mounting structure 134 at one end of the grinding head body near the base 14. The first mounting structure 133 and the second mounting structure 134 can be formed, for example, by drilling. The first mounting structure 133 can be a threaded hole, and the second mounting structure 134 can be a mounting groove. The specific methods for forming the first mounting structure 133 and the second mounting structure 134 have been described above and will not be repeated here.

[0078] In some embodiments, a base 14 may be formed, such as Figure 6a and Figure 6b As shown, the specific details may include: forming a base body, and opening a first opening 141 and a second opening 142 on the base body. In a direction perpendicular to the rotation axis of the grinding head 13 (i.e., the horizontal direction in the figure), the size of the first opening 141 is smaller than the size of the second opening 142, and the first opening 141 and the second opening 142 penetrate through the base body. The specific method for forming the base 14 has been described above and will not be repeated here.

[0079] In some implementations, an installation component 15 may be formed, such as Figure 6a and Figure 6b As shown, the specific components may include a first part 151 and a second part 152 that are fixed together. The first part 151 extends along the axis of rotation of the grinding head 13 (i.e., along the vertical direction in the figure), and the second part 152 extends perpendicular to the extension direction of the first part 151. For example, the mounting component 15 may be a screw.

[0080] In some implementations, such as Figure 6a and Figure 6b As shown, the mounting assembly 15 is used to mount the base 14 to the end of the grinding head 13 away from the drive member, including: passing the first part 151 through the first opening 141 and the second opening 142 and fixing it to the first mounting structure 133, and placing the base 14 in the second mounting structure 134 so that the base 14 and the second part 152 are rotatably connected.

[0081] In some implementations, such as Figure 6a and Figure 6b As shown, the mounting assembly 15 is used to mount the base 14 to the end of the grinding head 13 away from the drive member. The assembly further includes: forming a washer 16 on the upper surface of the base 14; securing the first part 151 through the first opening 141 and the second opening 142 to the first mounting structure 133; and placing the base 14 within the second mounting structure 134. The washer 16 is rotatably connected to the grinding head 13. For example, the washer 16 can be formed by bonding a smooth, wear-resistant material to the upper surface of the base 14.

[0082] In some implementations, such as Figures 1 to 6b As shown, the circumferential surface of the grinding head 13 is the grinding surface. After the base 14 is installed on the end of the grinding head 13 away from the drive component using the mounting component 15, the grinding surface is also hardened or rust-proofed. The resulting grinding head 13 has good wear resistance and grinding effect.
