Patent ID: 6979214

Claim:
A connecting device with an adjustable rotary structure comprising: a cruciform connector; an upper side of the cruciform connector having a slot; a rotary joint having an upper cover and a lower cover; the upper cover having two posts and the lower cover having two holes; the upper cover having a first recess, a first track and a first stop wall; the lower cover having a second recess, a second track and a second stop wall; a receiving chamber being formed by combining the upper cover and the lower cover; an inner side of the rotary joint being formed as a cruciform hollow space which is capable of receiving the cruciform connector; a center of the rotary joint being extended with a hollow post; an outer side of the hollow post being formed with two annular trenches; a semi-circle rings being embedded into the two annular trenches; an elastic buckling ring serving to enclose one of the annular trenches; the other annular trench serving to buckle the edges of the via holes of a satellite receiver; an actuating shaft being installed in the receiving chamber; a head end of the actuating shaft having two trenches at two lateral sides thereof for receiving the first and second tracks; one distal end of the actuating shaft opposite to the head end having at least one pin which is an compressible conductive metal; the distal end of the actuating shaft having at least one guide groove; a spring enclosing a middle section of the actuating shaft; the spring serving to resist against the first and second stop walls so that the actuating shaft moves reciprocally; an interface seat having a first ring at one end thereof and a second ring at another end thereof; at least one blocks extending from the first ring; the two blocks being capable of inserting into the guide groove; the cruciform connector being buckled to the second ring; the second ring having an elastic pin capable of being embedded into the slot so that the cruciform connector is movable in the slot; the rotary joint being buckled between the first ring and the second ring of the interface seat; the cruciform connector passing through the second ring to be embedded into the cruciform hollow space to push the head end of actuating shaft to move towards one side; and then the cruciform connector being rotated so that a cruciform rib at a front end thereof moves to an inner side to the cruciform hollow space to be buckled therein; thereby the rotary shaft and the interface seat can be detached and assembled rapidly.
