[0025] Embodiments will be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof and show, by way of illustration, specific exemplary embodiments. The embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the invention. However, the embodiments can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. Accordingly, the following detailed description is not limiting.

[0026] Figure 1 and Figure 2 are respectively a sectional view and an exploded view of a dual-purpose joint according to an embodiment of the present invention. Refer to Figure 1 and Figure 2 , the joint 1 includes a joint pipe 10, a conversion nut 11, a fixed pipe 12, an adjusting stud 13, a fixed set screw 14, and a positioning set screw 15. The first end of the fixed pipe 12 may have a fixed nut 123, which is fixed to one end of the joint pipe 10. The fixing manner of the fixed nut 123 and the joint pipe 10, for example but not limited to: tight fit. The rotating nut 11 is rotatably connected to the second end of the fixed pipe 12. In this embodiment, the rotating nut 11 has a connected, cylindrical nut 111 and a rib 112, and the rib 112 is exactly arranged in the cylindrical groove 120 at the second end of the fixed pipe 12.

[0027] Refer to Figure 1 and Figure 2 , the pipe wall of the fixed pipe 12 has a first through hole 121 and a second through hole 122. The rib 112 of the rotating nut 11 has an annular groove 1120. The fixed set screw 14 passes through the first through hole 121, and its end is arranged in the annular groove 1120. The fixed set screw 14 is used to position the rotating nut 11 so that it cannot move along the axial direction of the fixed pipe 12. The adjusting stud 13 has a long and narrow positioning groove 131. The positioning set screw 15 passes through the second through hole 122, and its end is arranged in the positioning groove 131. The adjusting stud 13 is threadably coupled to the rotating nut 11 and the fixed nut 123. For example, in this embodiment, both ends of the adjusting stud 13 have external threads, and the rotating nut 11 and the fixed nut 123 have internal threads to threadably engage the external threads of the adjusting stud 13. In addition, although the fixed set screw 14 and the positioning set screw 15 are in the form of screws in this embodiment, non-screw elements with similar shapes can also be used.

[0028] With the above configuration, when the rotating nut 11 is rotated, the adjusting stud 13 moves forward or backward along the axial direction of the fixed pipe 12. Figure 3 and Figure 4 are schematic diagrams of the operation of the rotating nut 11. Refer to Figure 3, the positioning setscrew 15 abuts against the second end 1312 of the positioning groove 131. When the user rotates the rotating nut 11 in a single direction, such as clockwise, the adjusting stud 13 moves backward along the axial direction of the fixed tube 12, so that part of the adjusting stud 13 is inserted into the fixed tube 12. As Figure 4 shown, when the user continues to rotate the rotating nut 11 in a single direction, such as clockwise, more parts of the adjusting stud 13 are inserted into the fixed tube 12 until the adjusting stud 13 is flush with the surface of the rotating nut 11. At this time, the positioning setscrew 15 abuts against the first end 1312 of the positioning groove 131, and the adjusting stud 13 cannot continue to move backward along the axial direction of the joint 1.

[0029] See Figure 4 , the initial position of the positioning setscrew 15 is located at the first end 1311 of the positioning groove 131. When the user rotates the rotating nut 11 in a single direction, such as counterclockwise, the adjusting stud 13 moves forward along the axial direction of the fixed tube 12, thereby exposing part of the adjusting stud 13. When the user continues to rotate the rotating nut 11 in a single direction, such as counterclockwise, more parts of the adjusting stud 13 are exposed until the positioning setscrew 15 abuts against the second end 1312 of the positioning groove 131, as Figure 3 shown.

[0030] When the adjusting stud 13 is moved to the position as Figure 4 shown, that is, the adjusting stud 13 is flush with the rotating nut 11. At this time, the joint 1 is adapted to insert the fixed tube 12 into the jack (not shown) of an audio device, where the outer diameter of the fixed tube 12 matches the aperture of the jack.

[0031] When the adjusting stud 13 is moved to the position as Figure 3 shown, at this time, the joint 1 is adapted to insert the adjusting stud 13 into the jack (not shown) of another audio device, where the diameter of the adjusting stud 12 matches the aperture of the jack.
