A quick plugging set of pneumatic tools including a connector, a steel ball seat and a tailstock, wherein the steel ball seat and the ball head of the connector are integrated completely through stamping and covering by a friction ring coordinated with a holding groove with thin cladding at the outer end of the steel ball seat providing the connector with angle-adjustment feature; a prefabricated covering interpolation segment at the rear portion of the connector integrates with the tailstock, a corresponding ring groove is placed therein, and a bolt hole drilled on the side of the tailstock penetrating the ring groove; a pre-determined number of the steel balls are filled into the ring groove through the bolt hole to provide the connector with rotary movement thus allowing the quick plugging set of pneumatic tools to have arbitrary angle adjustment and flexible rotation. |
