Abstract:
A pneumatic tool apparatus, comprising:a tool body having an annular body end face and having an interior cavity; a swivel backhead having an annular flange complementary to the annular body end face and having a backhead body extending from the annular flange away from the tool body, the swivel backhead having a passageway therethrough in communication with the interior cavity of the tool body, and the annular flange defining a swivel axis; a retainer ring connected to the tool body and having a radially inward extending flange with an opening defined therethrough, the backhead body extending through the opening with the annular flange of the swivel backhead being held loosely enough between the annular body end face and the retainer flange so that the swivel backhead can rotate about the swivel axis; a handle attached to the backhead body; a pneumatic control valve mounted in the passageway of the swivel backhead for controlling flow of air therethrough; and a multi-position releasable locking mechanism for selectively locking the swivel backhead and handle in one of a plurality of rotational positions about the swivel axis relative to the tool body.
