ABSTRACT:
A rotation speed regulating mechanism for pneumatic tools includes a movable airflow knob coupled on the periphery of an air intake member through screw threads. The airflow knob can be turned to adjust the size of an air inlet of the air intake member in a stepless fashion to regulate airflow entering an pneumatic tool so that the rotation speed of the pneumatic tool may be regulated in a stepless manner. Use of the pneumatic tool is more effective and convenient.
