Grinding and cleaning tool

Abstract

A grinding and cleaning tool, comprising a shaft, a driven member, a first grinding body, and a second grinding body. The shaft has a driving end and a driven end. The shaft is provided with a first end face at the driving end, and the driven end is adapted to be directly or indirectly driven by a power tool. The driven member is sleeved on the shaft and configured to rotate synchronously with the shaft. The driven member is provided with a second end face. The first grinding body is disposed on the first end face, and the second grinding body is disposed on the second end face.

1 . A grinding and cleaning tool comprising:
 a shaft having a driving end and a driven end, wherein the shaft is provided with a first end face at the driving end, and wherein the driven end is adapted to be directly or indirectly driven by a power tool;   a driven member sleeved on the shaft and configured to rotate synchronously with the shaft, and wherein the driven member is provided with a second end face;   a first grinding body disposed on the first end face; and   a second grinding body disposed on the second end face.   
     
     
         2 . The grinding and cleaning tool of  claim 1 , wherein the driven member is configured to rotate synchronously with the shaft along a rotation axis, wherein the first end face and the second end face are respectively perpendicular to the rotation axis, and wherein the first grinding body protrudes along the rotation axis beyond the second grinding body by at least a height. 
     
     
         3 . The grinding and cleaning tool of  claim 2 , wherein the first grinding body extends radially along the rotation axis and abuts against the second grinding body. 
     
     
         4 . The grinding and cleaning tool of  claim 2 , wherein the shaft is provided with an engaging portion and a body portion along the rotation axis, wherein the first end face is formed on the body portion, wherein the driven member is provided with an engaging hole sleeved on the engaging portion along the rotation axis, and wherein the second grinding body is provided with a bore sleeved on the body portion along the rotation axis. 
     
     
         5 . The grinding and cleaning tool of  claim 4 , wherein the engaging portion and the engaging hole have corresponding polygonal cross sectional shapes. 
     
     
         6 . The grinding and cleaning tool of  claim 5 , wherein the engaging portion is a hexagonal prism, and wherein the engaging hole is a corresponding hexagonal hole. 
     
     
         7 . The grinding and cleaning tool of  claim 4 , wherein the shaft is further provided with a limiting groove adjacent to the engaging portion, wherein the limiting groove is formed on an outer surface of the shaft and engaged with a limiting member, and wherein the limiting member abuts against the engaging portion. 
     
     
         8 . The grinding and cleaning tool of  claim 2 , wherein the shaft is provided with a first through hole penetrating the driving end and the driven end along the rotation axis, and wherein the first grinding body is provided with a second through hole aligned with the first through hole along the rotation axis. 
     
     
         9 . The grinding and cleaning tool of  claim 8 , wherein the shaft is further provided with a driven portion at the driven end, and the first through hole penetrates the driven portion, wherein an outer surface of the driven portion is provided with at least one groove, and wherein the at least one groove is configured to engage with a fastener of a sleeve to connect the driven portion to the sleeve. 
     
     
         10 . The grinding and cleaning tool of  claim 8 , wherein the first through hole has a first segment aligned with the second through hole and a second segment communicating with the first segment, wherein the shaft is further provided with a driven portion at the driven end, wherein the driven portion is fixed to the second segment of the first through hole, and wherein the driven portion is hexagonal. 
     
     
         11 . The grinding and cleaning tool of  claim 4 , wherein the shaft is further provided with at least one biasing portion extending from the body portion in a direction parallel to the rotation axis, and at least one limiting portion disposed on the at least one biasing portion, wherein the at least one biasing portion is configured to pivot relative to the body portion and switch between a locking position and a releasing position, wherein the at least one limiting portion extends radially along the rotation axis, and wherein the at least one limiting portion selectively abuts against the driven member as the at least one biasing portion switches between the locking position and the releasing position. 
     
     
         12 . The grinding and cleaning tool of  claim 11 , wherein the shaft is further provided with a driven portion at the driven end, and wherein a gap is radially formed between the driven portion and the at least one biasing portion along the rotation axis, allowing the at least one biasing portion to pivot relative to the body portion. 
     
     
         13 . The grinding and cleaning tool of  claim 11 , wherein the number of both the at least one biasing portion and the at least one limiting portion is two, wherein the two biasing portions are respectively located on opposite sides of the body portion, and wherein the two limiting portions are respectively disposed on the two biasing portions.
