Handheld belt sander

Abstract

A handheld belt sander includes a main body having a motor connected with a rotating wheel and a base extending along a first straight direction. A mount is fixed to the base. A straight rod extending along a second straight direction with no bend is disposed on the mount. The second straight direction is upward from the first straight direction at a raise angle. A roller is disposed on the straight rod. A flat plate extending under the straight rod is disposed on the mount. A grinding belt encircles the rotating wheel, the roller and the flat plate and is tightened by the straight rod. A lower part of the grinding belt under the straight rod abutted against the flat plate. A space to be entered for the grinding belt formed between the straight rod and an upper part of the grinding belt above the straight rod.

What is claimed is: 
     
         1 . A handheld belt sander, comprising:
 a main body having a motor connected with a rotating wheel; a handle formed at a rear end of the main body; a base formed at a fore end of the main body and extending along a first straight direction, the base having a first positioning portion;   a mount disposed on the base, the mount having a second positioning portion to be fixed to the first positioning portion to prevent the mount from rotating relative to the base; a straight rod extending along a second straight direction with no bend disposed on the mount, wherein the second straight direction is upward from the first straight direction at a raise angle; a roller disposed at an end of the straight rod; a flat plate disposed on the mount, the flat plate extending under the straight rod;   a grinding belt encircling the rotating wheel, the roller and the flat plate and tightened by the straight rod, a lower part of the grinding belt under the straight rod abutted against the flat plate to be defined as a flat straight section, a space to be entered for the grinding belt formed between the straight rod and an upper part of the grinding belt above the straight rod, so that the grinding belt moves into the space after being pressed.   
     
     
         2 . The handheld belt sander as claimed in  claim 1 , wherein the mount extends along the second straight direction and has a hole extending along the second straight direction for coupling with the straight rod. 
     
     
         3 . The handheld belt sander as claimed in  claim 1 , wherein the mount extends along the first straight direction and has a hole extending along the second straight direction for coupling with the straight rod. 
     
     
         4 . The handheld belt sander as claimed in  claim 1 , wherein the raise angle is 15 degrees. 
     
     
         5 . The handheld belt sander as claimed in  claim 1 , wherein the first positioning portion is one of a concave and a convex in a shape of noncircle while the second positioning portion is the other.
