Abrasive wheel which can be provided with a sandpaper

Abstract

An abrasive wheel provided with a piece of sandpaper, including a columnar main body and a tension member. A first surface is formed on the periphery of the main body. The main body forms first and second storage chambers. The first surface forms a channel communicating with the first storage chamber. The second storage chamber extends on one side of the channel, so that one end of a piece of sandpaper enters the first storage chamber to form a restricted part. The other end of the sandpaper is located in the second storage chamber. The tension member is disposed in the first storage chamber, and is provided with a guide slot, so that the restricted part enters the guide slot through the channel, and the restricted part is guided to adhere to the circumferential wall as the tension member rotates, the sandpaper stretches tight and adheres to the first surface.

I claim: 
     
         1 . An abrasive wheel which can be provided with a piece of sandpaper, including:
 a columnar main body, the main body has a mounting end and a driven end; the mounting end is opposite to the driven end in the axial direction of the main body; a first surface is formed on the circumference of the main body; the first surface is located between the mounting end and the driven end, so that a piece of sandpaper is arranged on the first surface; a first storage chamber and a second storage chamber are formed inside the main body; the first storage chamber and the second storage chamber extend into the main body from the mounting end respectively; the first surface forms a channel, one end of the channel extends at the mounting end, the other end of the channel points at the driven end; the channel extends into the main body, and the channel communicates with the first storage chamber; the second storage chamber extends on one side of the channel, so that one end of the sandpaper enters the first storage chamber to form a restricted part; the other end of the sandpaper is located in the second storage chamber; the first storage chamber has a compass circumferential wall; and   a tension member, the tension member is disposed in the first storage chamber, and can rotate in the first storage chamber; the tension member has a guide slot, the guide slot extends from the periphery of the tension member into the tension member, so that the restricted part enters the guide slot through the channel, and the restricted part is guided to adhere to the circumferential wall as the tension member rotates, and then the tension member and the circumferential wall oppositely press and localize the restricted part, and the sandpaper is stretched tight and adhering to the first surface.   
     
     
         2 . The abrasive wheel which can be provided with a piece of sandpaper defined in  claim 1 , wherein the tension member has a pushing part, so that the pushing part pushes the restricted part to move towards the channel, and then the sandpaper can be removed. 
     
     
         3 . The abrasive wheel which can be provided with a piece of sandpaper defined in  claim 2 , wherein the tension member has a second surface, the second surface is formed on the periphery of the tension member, so that the circumferential wall and the second surface oppositely press and localize the restricted part; the tension member forms a second slot wall on one side of the guide slot; the pushing part is formed at the conjoiner of the second slot wall and the second surface. 
     
     
         4 . The abrasive wheel which can be provided with a piece of sandpaper defined in  claim 2 , wherein the tension member is provided with a slot, the slot extends from the periphery of the tension member into the tension member; the periphery of the tension member forms a second surface and a third surface between the guide slot and the slot, so that the circumferential wall and the second surface oppositely press and localize the restricted part; the tension member forms a third slot wall on one side of the slot; the pushing part is formed at the conjoiner of the third slot wall and the third surface. 
     
     
         5 . The abrasive wheel which can be provided with a piece of sandpaper defined in  claim 1 , wherein the main body is provided with a baffle, the tension member is located between the baffle and the driven end; the baffle stops the tension member, so as to localize the tension member on the main body. 
     
     
         6 . The abrasive wheel which can be provided with a piece of sandpaper defined in  claim 5 , wherein the mounting end forms a compass flange in axial direction, the flange is disposed on the periphery of the baffle, so as to localize the baffle. 
     
     
         7 . The abrasive wheel which can be provided with a piece of sandpaper defined in  claim 5 , including a shaft lever and a bolt, wherein the shaft lever axially contacts the driven end, so that the shaft lever is configured on a rotary driving device; the bolt axially penetrates the baffle and the tension member is screwed on the shaft lever, so as to localize the baffle. 
     
     
         8 . The abrasive wheel which can be provided with a piece of sandpaper defined in  claim 7 , wherein the driven end forms a joint holder in axial direction, the joint holder forms a polygonal embedding groove in axial direction; the shaft lever is provided with an insert fitting the embedding groove; the insert is embedded in the embedding groove, so that the shaft lever axially contacts the driven end. 
     
     
         9 . The abrasive wheel which can be provided with a piece of sandpaper defined in  claim 1 , wherein the tension member forms an operation hole in axial direction, so that a hand tool can be embedded in the operation hole to pull the tension member to rotate. 
     
     
         10 . The abrasive wheel which can be provided with a piece of sandpaper defined in  claim 1 , wherein the first surface is approximately in the shape of circular arc.
