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.
FIELD OF THE INVENTION The present invention relates to a universal quick connection unit for hydraulic or pneumatic tools and which allows the pipe to be rotated in two different directions relative to the hydraulic or pneumatic tool.
BACKGROUND OF THE INVENTION A conventional connection between a hydraulic or pneumatic tool 50 and a pipe 52 through which the pressurized air is delivered into the hydraulic or pneumatic tool 50 is shown in FIG. 1 and generally includes a male part 51 and a female part 53. The male part 51 is connected to the inlet of the hydraulic or pneumatic tool 50, and the female part 53 is removably connected to the male part 51. The pipe 52 is dragged, pulled, or even twisted during operation of the hydraulic or pneumatic tool 50. Since the female part 53 cannot be rotated relative to the hydraulic or pneumatic tool 50, the pipe 52 is easily twisted to affect the supply of the pressurized air into the hydraulic or pneumatic tool 50.
SUMMARY OF THE INVENTION The present invention relates to a quick connection unit for hydraulic or pneumatic tools, and the connection unit comprises a female part having an axial passage defined therethrough and a lateral tube extending radially from the female part. A lateral passage is defined through the lateral tube and communicates with the axial passage. 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 pivotable about an X-axis of the lateral passage. The vertical tube includes an inlet which communicates with an interior of the horizontal tube and the lateral passage. A pipe is connected to the vertical tube.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a first conventional connection unit connected with a hydraulic or pneumatic tool;
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIGS. 3, 4, and 6, the quick connection unit for connecting a pipe 64 to a hydraulic or pneumatic tool of the present invention comprises a female part 10 which has an axial passage 11 defined therethrough and a lateral tube extending radially from the female part 10. A lateral passage 12 is defined through the lateral tube and communicates with the axial passage 11. The lateral tube of the of the female part 10 includes a threaded hole 13 defined through a wall thereof.
