AI Technical Summary
Existing handheld belt sanders are cumbersome to install and remove, and the fixed configuration of the main and auxiliary pulleys results in a small contact area between the sanding belt and the workpiece surface, affecting processing efficiency.
A handheld belt sander was designed. The tension wheel can be rotated through the rotating disc and connecting plate structure, which facilitates belt replacement. The tension of the belt can be adjusted by rotating the rotating disc to increase the contact area with the workpiece. At the same time, the belt is fixed by the limiting groove and the abutment rod to ensure that it remains taut during processing.
This improves the ease of installation and replacement of the sanding belt and increases the contact area between the sanding belt and the workpiece surface, thereby improving processing efficiency.
