In said structure, it is integrated with the plain grinding of hand-held, polishing small arc-shaped, the polishing machining functions such as orthodrome and angle polishing；During polishing roundlet arc-shaped workpiece, it is possible to produce pipe wheel support and regulate the position of polishing station band, when not in use, it is possible to rotate into pack up and be fixed in frame；Driven tail wheel move left and right adjustment, it may be achieved the requirement that the abrasive band of different length uses on a machine.

For realizing machine folder polishing further, it is additionally provided with the V-arrangement folder of clamping workpiece, described V-arrangement folder is installed on V by feed screw nut's feed mechanism and grinds on frame, V-arrangement folder the rotation being fed through handle strip movable wire bar and realize, the grinding angle of V-arrangement folder regulates the beat realization being to be ground frame by V, and when general polishing, V folder can be removed.

The mode that described driven tail wheel left and right adjustable position adopts is: the follower shaft of driven tail wheel is snug fit in the left and right bar-shaped trough offered in frame, fixes after position adjustments puts in place and by locking member.

A kind of structure that described tensioning adjustment wheel scalable abrasive band wanders off includes swing arm, the arm body of described swing arm is hinged in frame, it is provided with extension spring between drive end and the frame of swing arm, the tensioning of tensioning adjustment wheel adjusts wheel shaft hinge and is installed on the driven end of swing arm, under the effect of extension spring, tensioning adjustment wheel is flared out, thus auto-tensioning abrasive band；The tensioning of hinge position adjusts and is provided with block bottom the axis body of wheel shaft, described block be limited in frame arrange thrust screw, wander off situation according to abrasive band, regulate thrust screw and adjust the restraining position of block, and then adjust the angle of tensioning adjustment wheel shaft and horizontal plane and reach to regulate the purpose that abrasive band wanders off.

A kind of version of described actuating device includes frequency conversion motor and pulley transmission mechanism, is equipped with converter and can realize infinitely variable speeds regulation and control.

Described drivewheel conventionally adopts rubber tire, prevents abrasive band from skidding with increasing friction force, better transmits power.

Steel plate cutting thick for described frame 20mm～30mm makes, and loaded down with trivial details structure can be avoided to process.

Beneficial effects of the present invention:

Belt sander of the present invention integrates hand sand, machine polishing, and the abrasive band installation of random length can be realized by the adjustment of driven tail wheel, also can change the space structure shape in abrasive band further and realize the processing of particular/special requirement, embody multifunctional all feature, belong to the industry to initiate, maintain the leading position in like product.
