[0002] Sandblasting is a professional process for treating the surface of metal parts. The negative pressure air generated by the pump body compresses the sand particles and sprays them on the outer wall of the workpiece at a certain speed. The impact force between the sand and the surface of the metal tool is used to clean the corrosion layer and make it smoother. The coarseness and fineness can also be adjusted. However, general sandblasting devices often lack rotational power when inserting the pipe body. If both sides are inserted into the fixture, it will be difficult to evenly spray every part of the surface of the pipe, which has limitations.

[0003] Now, a new type of sandblasting device for surface treatment of metal pipe fittings of sports equipment is proposed to solve the above problems. Utility Model Content

[0014] (1) By welding a sleeve block at the bottom of the suspension rod, the round tube is horizontally inserted between the sleeve blocks on both sides and overlapped on the top between the movable plates. The cylinder on the top of the rotary block is started to quickly lift the round tube supported between the side plates to form a clamping state with the top fixed plate, thereby preventing the round tube from shaking during movement.
