AIR EXHAUST METHOD OF A PNEUMATIC TOOL AND DEVICES THEREOF

摘要

An air exhaust method of a pneumatic tool and devices thereof include a tool body having an air guide element, a brake element sheathed at the air guide element, and an adjustment element fixed at the brake element. The air guide element contains a front and rear air guide structure, and the brake element includes a front and rear movable guiding structure corresponding to the air guide structures. Upon using the pneumatic tool, the front and rear movable guiding structure of the brake element is superimposed to the front and rear air guide structure of the air guide element, discharging air backward to prevent from suspension of dust to facilitate drilling; or the front and rear movable guiding structure escapes from the front and rear air guide structure of the air guide element, discharging debris forward to facilitate cutting, by rotating the adjustment element clockwise or counterclockwise.

主权项

1. An air exhaust method of a pneumatic tool and devices thereof, comprising a tool body which is provided with an air guide element, a brake element which is sheathed at the air guide element, and an adjustment element which is fixed at the brake element to drive the brake element to rotate; the air guide element being provided with a front and rear air guide structure and the brake element being provided with a front and rear movable guiding structure corresponding to the air guide structures, such that when the pneumatic tool is used, the brake element being driven by clockwise or counterclockwise rotation of the adjustment element, allowing the front and rear movable guiding structure of the brake element to be superimposed to the front and rear air guide structure of the air guide element, so that air is discharged backward to prevent from suspension of dust to facilitate drilling, or allowing the front and rear movable guiding structure to escape from the front and rear air guide structure of the air guide element, so that debris is discharged forward to facilitate cutting.
