Benefits of technology

[0005]One object of the present invention is to provide an inlet air way control structure of an air tool which can change the inlet air way for controlling a clockwise or counterclockwise rotation of the air tool.
[0006]Another object of the present invention is to provide a better operation convenience of the air tool so that the user can, by only one hand, hold the tool and control the ON / OFF and rotation direction at the same time, which is also suitable for the plastic housed air tool.

Problems solved by technology

However, in fact, there is a problem existed in the above-described patent, that is, the adjusting element for controlling a clockwise or counterclockwise rotation of the air tool is mounted at the rear end of the whole body of the air tool.
According to this, it is obvious that the user may have difficulty in operating the tool and controlling / changing the rotation direction of the air tool at the same time.
This is quite inconvenient for the user, whose both hands always have to respectively hold the air tool and the processing object, and also causes a low operation efficiency.

Embodiment Construction

[0013]Please refer to FIG. 1 which shows a structural drawing of a preferred embodiment in the present invention. As shown in FIG. 1, this embodiment of the present invention includes an air tool 10 which has a handle 11 and an inlet 12 located in the lower end of the handle 11. The inlet 12 provides a pressed atmosphere into an inlet channel 13. The inlet channel 13 has a valve shelve 14 mounted thereon and also has a first inlet air way 131 and a second inlet air way 132. The valve sleeve 14 has plural through holes 141, 142, 143 mounted thereon respectively connected to the inlet channel 13 and the first and the second inlet air ways 131, 132, and the peripheral of the through holes 141, 142, 143 has a resin pad 20 for avoiding leaking. The first inlet air way 131 and the second inlet air way 132 are communicated with a cylinder 15 inside the air tool 10 and the first and the second inlet air ways 131, 132 are respectively the clockwise and the counterclockwise inlet way of the c...

Abstract

An inlet air way control structure of an air tool includes a valve sleeve mounted on an inlet channel inside the air tool and communicated with a first inlet air way and a second inlet air way, and a control shaft penetrating the valve sleeve, thereby the control shaft can change the inlet air way of the air tool so that the air tool can be controlled to have a clockwise or counterclockwise rotation. Moreover, the valve sleeve has a fixing element for being fixed with the cylinder, and thus the inlet air way control structure of the present invention can be applied to a plastic housed air tool. Furthermore, owing to the control shaft, the user can operate the rotation direction of the air tool by only one hand so as to achieve a great convenience.

Description

FIELD OF THE INVENTION[0001]The present invention is related to an inlet air way control structure of an air tool, and more particularly to a plastic housed air tool having a fixing element mounted on a valve sleeve for fixing with a cylinder.BACKGROUND OF THE INVENTION[0002]Usually, conventional air tools use pressed atmosphere to drive the air motor inside an air tool set so as to provide all kinds of operations of the air tool, wherein the air motor set can have a clockwise or a counterclockwise status through controlling the air inlet direction of the pressed atmosphere. For example, R.O.C. Patent Publication No. 569885 “Improved structure for air way control mechanism” disclosed an improvement for the air way control mechanism including a cylinder which has a column cylinder barrel, an air chamber located inside the cylinder barrel, and two directional air holes passing through two corresponding walls at one end of the cylinder for communicating the air chamber with the outside...
