Abstract: A quick connection unit for hydraulic or pneumatic tools includes a female part having an axial passage and a lateral tube. A fixing bolt extends into the axial passage, and the female part is pivotable about the fixing bolt along a Y-axis. A path is defined in the shank of the fixing bolt which is connected to the hydraulic or pneumatic tool. An L-shaped male part includes a horizontal tube and a vertical tube. The horizontal tube is rotatably connected to the lateral tube of the female part and communicates with the lateral passage in the lateral tube and the axial passage. The horizontal tube of the male part is pivotable about an X-axis of the lateral passage. A pipe is connected to an inlet of the vertical tube of the male part. The pipe can be rotated along the two axes relative to the hydraulic or pneumatic tool.

Abstract: A quick connector includes a connector body comprising longitudinal and lateral bores communicating each other; a male member adapted to secure to a coupling end of a portable power tool, and a stepped-diameter section rotatably secured to the connector body; and an L-shaped fitting having one end adapted to connect to a line for conveying pressurized fluid and the other end adapted to connect to the lateral bore. An outer surface of the other end of the L-shaped fitting comprises a retaining mechanism for securing the connection of the L-shaped fitting to the connector body and allowing a free turning of the L-shaped fitting about the connector body. The quick connector is adaptable.
