Claim:
A connecting structure of a holding unit and a connecting rod for an MP3 device, comprising: (a) an axially extended connecting rod; (b) a coupling unit including: an angle main body having first and second end portions perpendicular to each other; the first end portion of the angle main body having an annular recess, an annular protrusion adjacent to a lower edge of the annular recess, and a protrusion on the annular recess; a connecting member including left and right shell parts, the connecting member being connected to the first end portion of the angle main body at one end, and the connecting rod at other end thereof so as to allow the angle main body to be turned relative to the connecting rod with the first end portion coaxially disposed relative to the connecting rod; the connecting member having an annular recess on an inner circumferential side thereof, and a plurality of stopping protrusions on the inner annular recess; the connecting member being positioned around the first end portion of the angle main body with the protrusion of the angle main body being confined within the inner annular recess thereof, and the stopping protrusions thereof being confined within the annular recess of the angle main body for limiting turning motion of the angle main body relative to the connecting rod, the left and the right shell parts having a plurality of locating holes and locating protrusions; the locating protrusions being fitted in respective ones of the locating holes when the left and the right shell parts are coupled together; and a clamp ring being positioned around both the left and the right shell parts to hold the left and the right shell parts firmly together; and, (c) a holding unit for holding an MP3 device, the holding unit including a back shell part; the holding unit being connected to the second end of the angle main body of the coupling unit so as to be turnable relative to the coupling unit; whereby the holding unit can be angularly moved about a vertical axis as well as a horizontal one.
