Abrasive wheel which can be provided with a sandpaper

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.
