Abstract
This invention discloses an air intake adjusting assembly for pneumatic tools, which rearranges the air intake adjusting assembly between the main body and the air intake section of a pneumatic tool, such that the air intake adjusting assembly will not be covered when a user is operating the pneumatic tool, and also provides a comfortable grip for users. The air intake adjusting assembly according to the present invention comprises an air intake adjusting knob being installed at the external periphery of an air intake member for adjusting the diameter of an adjusting hole of the air intake member by steplessly rotating the air intake adjusting knob as to adjust the air flow of the pneumatic tool and achieve the effect of steplessly controlling the rotation speed of the pneumatic tool.

An air intake adjusting assembly for pneumatic tools, being installed between a main body and an air intake section for inputting a gas into a pneumatic tool and comprising:
- an air intake member, being in a hollow tubular shape and having a partition board disposed therein for separating an air inlet and an air outlet and said air inlet and said air outlet being coupled with said air intake section and said main body respectively and an adjusting hole disposed individually at said air inlet and said air outlet;
- and
- an air intake knob, being rotably disposed at the external periphery of said air intake member and having an adjusting groove corresponding to said adjusting hole;
- thereby when said air intake adjusting knob is rotated, said adjusting groove displaces with respect to said adjusting hole to adjust the diameter of said adjusting hole for covering said adjusting groove as to adjust the air flow entering from said air intake section into said main body.
