[0002] Abrasive belt grinder is a common metal processing equipment, mainly used for grinding metal workpieces. Abrasive belt grinder is usually composed of grinding head, conveyor belt and worktable. Its working principle is to use the rotating abrasive belt to grind the workpiece surface at high speed.

[0003] When people use a belt grinder, they usually hold the workpiece in hand and place it against the rotating belt in the grinder. However, there are certain safety hazards when people hold the workpiece for grinding. Therefore, the workpiece is usually fixed on a processing table so that the belt grinder can move in contact with the workpiece for grinding. However, when grinding at different positions on the outer surface of the workpiece, it is necessary to adjust the placement angle of the workpiece on the workbench so that the grinding surface of the workpiece and the outer surface of the belt are flush with each other, which increases the labor intensity of people adjusting the position of the workpiece and also has a certain impact on the overall grinding efficiency of the belt.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the belt grinder has the defect of being cumbersome to repeatedly adjust the position of the workpiece during use. Therefore, a multi-angle belt grinder is proposed to solve the above problem. Utility Model Content
