AI Technical Summary
Existing pneumatic tools are easily exposed to air when stored, which can lead to the entry of dust, moisture, or harmful gases, affecting their service life.
A safe storage device for pneumatic power tools was designed. The pneumatic tool is moved into an enclosed space by rotating the shaft, and lubricating oil is automatically injected through the air injection device and oil tank to form a protective oil film to prevent dust and harmful gases from entering.
It effectively prevents the entry of dust, moisture and harmful gases, extends the service life of pneumatic tools, and prevents rust through lubrication.
