Problems solved by technology

[0002] The existing single-friction plate pneumatic clutch is large in size and high in cost, and can only be used with an additional rotary joint; in addition, the existing pneumatic spur clutch cannot be separated and combined freely without stopping the engine, and the operator misuses it. One time will damage the clutch, so this product is very easy to damage...
