[0038] Referring to FIGS. 1 to 3, a grinding and cleaning tool according to a first embodiment of the present invention includes a driving member 10, a driven member 20, a first grinding body 30, and a second grinding body 40. The driving member 10 has a driving end 101 and a driven end 102. Additionally, the driving member 10 is provided with an end surface 11 at the driving end 101. The driven end 102 is adapted to be indirectly driven by a power tool. It is understood that the power tool can be a non-manual tool, such as an electric or pneumatic tool. The driven member 20 is sleeved on the driving member 10 and configured to rotate synchronously with the driving member 10 when driven by the power tool. The driven member 20 is provided with an end surface 21. The first grinding body 30 is disposed on the end surface 21 of the driven member 20, and the second grinding body 40 is disposed on the end surface 11 of the driving member 10. Accordingly, when the driving member 10 is driven by the power tool to rotate synchronously with the driven member 20, the first grinding body 30 and the second grinding body 40 can simultaneously grind and clean different parts of an object, such as a wheel rim.

[0039] In this embodiment, the first grinding body 30 and the second grinding body 40 may be integrally formed from coarse abrasive materials on the end surface 21 and the end surface 11, respectively. The coarse abrasive materials may be selected from currently known abrasive materials.

[0040] Furthermore, the driven member 20 is configured to rotate synchronously with the driving member 10 along a rotation axis L. The end surface 11 and the end surface 21 are respectively perpendicular to the rotation axis L, and the second grinding body 40 projects along the rotation axis L beyond the first grinding body 30 by at least a height H40. This allows both the end surface and the side surface of the second grinding body 40 to grind and clean an object. Additionally, the second grinding body 40 extends radially along the rotation axis L and abuts against the first grinding body 30.

[0041] To ensure that the driven member 20 can rotate synchronously with the driving member 10, the driving member 10 is provided with an engaging portion 12 and a body portion 13 along the rotation axis L. The end surface 11 is formed on the body portion 13. The driven member 20 is provided with an engaging hole 22 sleeved on the engaging portion 12 along the rotation axis L, and the first grinding body 30 is provided with a bore 31 sleeved on the body portion 13 along the rotation axis L. Furthermore, the engaging portion 12 and the engaging hole 22 have corresponding polygonal cross sectional shapes. In this embodiment, the engaging portion 12 is in the form of a hexagonal prism, and the engaging hole 22 is a hexagonal hole.

[0042] To prevent the driven member 20 from detaching from the driving member 10, the driving member 10 is further provided with a limiting groove 14 adjacent to the engaging portion 12. The limiting groove 14 is formed on the outer circumferential surface of the driving member 10 and is engaged with a limiting member 50, and the limiting member 50 abuts against the engaging portion 12.

[0043] Additionally, the driving member 10 is provided with a first through hole 15 extending through the driving end 101 and the driven end 102 along the rotation axis L, and the second grinding body 40 is provided with a second through hole 41 aligned with the first through hole 15 along the rotation axis L. This allows the second through hole 41 to accommodate smaller objects to be ground and cleaned.

[0044] In this embodiment, the driving member 10 is further provided with a driven portion 16 at the driven end 102, and the first through hole 15 extends along the rotation axis L through the driven portion 16. The outer circumferential surface of the driven portion 16 is provided with at least one groove 161, and the at least one groove 161 is configured to engage with a fastener 61 of a sleeve 60 to connect the driven portion 16 to the sleeve 60. In this embodiment, the number of grooves 161 may be six. Thus, the sleeve 60 can be connected to the power tool, enabling the driven end 102 to be indirectly driven by the power tool via the sleeve 60 to rotate the driven member 20.

[0045] Referring to FIGS. 4 to 6, a grinding and cleaning tool according to a second embodiment of the present invention is generally similar to the first embodiment, with the only difference being the structure of the driving member 10a. In this embodiment, the first through hole 15a has a first segment 151a aligned with the second through hole 41 of the second grinding body 40 and a second segment 152a communicating with the first segment 151a. The driving member 10a is further provided with a driven portion 16a at the driven end 102a, and the driven portion 16a is fixed to the second segment 152a of the first through hole 15a. The driven portion 16a is in the form of a hexagonal prism. Therefore, the driven portion 16a can be directly connected to the power tool, enabling the driven end 102a to be directly driven by the power tool to rotate the driven member 20.

[0046] Referring to FIGS. 7 to 9, a grinding and cleaning tool according to a third embodiment of the present invention is generally similar to the first embodiment, with the only difference being the structure of the driving member 10b.

The at least one biasing portion 14b is configured to pivot relative to the body portion 13b and switch between a locking position and a releasing position. The at least one limiting portion 15b extends radially along the rotation axis L, and the at least one limiting portion 15b selectively abuts against the driven member 20 as the at least one biasing portion 14b switches between the locking position and the releasing position. In other words, when the at least one biasing portion 14b is in the locking position, the at least one limiting portion 15b abuts against the driven member 20, preventing the driving member 10b from moving along the rotation axis L relative to the driven member 20. Conversely, when the at least one biasing portion 14b is in the releasing position, the at least one biasing portion 14b pivots toward the rotation axis L, causing the at least one limiting portion 15b to disengage from the driven member 20, allowing the driving member 10b to move along the rotation axis L relative to the driven member 20.

[0047] To enable the at least one biasing portion 14b to pivot relative to the body portion 13b, the driving member 10b is further provided with a driven portion 16b at the driven end 102b, and a gap 17b is radially formed between the driven portion 16b and the at least one biasing portion 14b along the rotation axis L. The at least one biasing portion 14b can pivot relative to the body portion 13b through the gap 17b when an external force is applied by the user, thereby switching from the locking position to the releasing position. Once the external force applied by a user is removed, the at least one biasing portion 14b can automatically return from the releasing position to the locking position. Furthermore, in this embodiment, the driven portion 16b is provided with a square hole for connecting to a power tool.

[0048] In this embodiment, the at least one biasing portion 14b and the at least one limiting portion 15b each consist of two components. The two biasing portions 14b are respectively located on opposite sides of the body portion 13b, and the two limiting portions 15b are respectively disposed on the two biasing portions 14b.

[0051] The driven member 20c is provided with a coupling hole 21c, an end surface 22c, and a second abutting portion 23c. The coupling hole 21c is detachably sleeved onto the coupling portion 11c, such that the driven member 20c is configured to be driven by the driving member 10c to rotate synchronously along a rotational axis L. The first abutting portion 12c detachably abuts against the second abutting portion 23c.

[0052] The first grinding body 30 is disposed on the end surface 22c of the driven member 20c. The first grinding body 30 may be made of an abrasive material and fixed to the end surface 22c of the driven member 20c.
