Abstract:
1. A quick plugging set of pneumatic tools comprising: a connector, in which a quick plugging connector installed at one end of the connector is used for interpolating and connecting with piping, and another end is shaped as a ball head; a reducing diameter neck is formed at a convergence portion between the ball head and the said quick plugging connector allowing the ball head to be placed within a holding groove inside a steel ball seat; one end of the steel ball seat includes a holding groove for holding the ball head of the connector, the outer end of the said holding groove is made of thin cladding with suitable width to cover the outer edge of a friction ring; the thin cladding will be stamped and folded after the ball head of the connector, a stop-leak rubber ring and the friction ring are put into the holding groove, thus combining the connector with the steel ball seats; another end of the steel ball seat consists of a covering interpolation segment with a reducing diameter for plugging into the tailstock, and a ring groove is placed at pre-determined position of the covering interpolation segment; and a tailstock includes a locking connection segment with external threads for combining with integrated tools at one end, and a hex rod segment with a covering interpolation groove inside it to connect with the covering interpolation segment of the steel ball seat at another end; a seal ring and a ring groove are placed at a pre-determined position within the covering interpolation groove, the ring groove and the ring groove of the steel ball seat correspondingly integrate to constitute a ring space; steel balls are inserted into the ring space; through a combination relationship between the ball head of the connector and the steel ball seat, the connector is provided with an arbitrary torsion angle adjustment feature, and through the steel balls inserted between the steel ball seat and the tailstock ring groove, the steel ball seat and the tailstock are provided with a relatively flexible rotation feature.
