Quick-release joint for two tubes

In a quick-release joint for two tubes, the quick-release joint having a first connector adapted to securely connect to a first tube, the first connector having a first inner lip formed on an inner surface of the first connector;

• a second connector adapted to securely connect to a second tube, wherein the second connector is pivotally connected to the first connector and is axially offset from the first connector, the second connector has a protrusion formed on an inner surface of the second connector and having an outer groove formed on the protrusion next to a top face of the second connector to correspond to the first inner lip;
• and
• a retainer formed on a side of the first connector and the second connector to move the first connector to align with the second connector such that the first inner lip is received in the outer groove of the protrusion to secure connection between the first connector and the second connector, wherein the improvements comprise:
• the retainer includes a first arm, a second arm, a cylindrical connector and a threaded bolt,
• wherein the first arm is securely connected to an outer surface of the first connector and has a tubular connector integrally formed with the first arm, the second arm is securely connected to an outer surface of the second connector, the threaded bolt extends through the cylindrical connector to be ready to abut an inner surface of the second connector,
• whereby before the extension of the threaded bolt, the first connector is mis-aligned with the second connector,
• after the threaded bolt threadingly extends further into the cylindrical connector to abut the inner surface of the second connector, the second connector is moved by the extension of the threaded bolt to axially align with the first connector.

The quick-release joint for two tubes, the quick-release joint comprising:

• a hollow, cylindrical first connector having a first protrusion formed and extending from a portion of an inner periphery of the first connector, a first groove defined at a joint of the first protrusion and the inner periphery of the first connector, a guide formed on an outer face of the first protrusion and securely engaged with the bottom face of the first connector and a first passage defined in the inner periphery of the first connector (40);
• a hollow, cylindrical second connector having a second protrusion formed and extending upward from a portion of an inner face of the second connector, a second groove defined at a joint of the second protrusion and the inner face of the second connector to correspond to the first passage, a guiding notch defined in a bottom face of the second connector to correspond to the guide and a second passage defined in the inner face of the second connector to correspond to the first groove of the first connector;
• and
• a push having a knob and a bolt having a first distal end securely connected to the knob and a second distal end extending into the second protrusion from an outer periphery of the second protrusion, such that after the first protrusion is extended into the second connector where an open space is defined, the knob is rotated to further extend the bolt into the second connector so that the second distal end of the bolt abuts an outer periphery of the first connector to push the mating between the first groove and the second passage and the mating between the second groove and the first passage.
