Abstract
The utility model provides an abrasive belt sander and belongs to the technical field of machines. The abrasive belt sander solves the problem that due to the fact that an existing polishing wheel converting mechanism can not stretch out or draw back, overmuch machine frame space is occupied. The abrasive belt sander comprises a machine frame, a driving wheel, a driven wheel and an abrasive belt, wherein the driving wheel, the driven wheel and the abrasion belt are arranged on the machine frame. A connecting rod is hinged to the machine frame. The end of the connecting rod is fixedly provided with a polishing wheel, and the edge of the polishing wheel directly faces the inner side of the abrasive belt. The machine frame is provided with a drive part connected with the connecting rod. The polishing wheel can abut against the inner side of the abrasive belt when the drive part drives the connecting rod to rotate around a hinged point. The abrasive belt sander has the advantage that small machine frame space is occupied when the polishing wheel is not used.
