[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) During installation, the operator removes the connector, then inserts the support medium and the insulating medium into the internal mixable cavity of the housing, and makes the insulating medium rest on the two support hoops. Then, the operator pushes the retaining disc and the transmission rod to move through the handwheel. When the transmission rod moves, it slides along the inside of the upper sliding sleeve, and at the same time drives the limit rod to slide along the inside of the limit groove, increasing the stability of the transmission rod during movement. When the transmission rod moves, it also drives the positioning block to move. When the positioning block moves, due to the restriction of the support plate, the positioning block is prevented from rotating and falling due to the action of gravity, ensuring that the transmission rod does not rotate by itself. The retaining disc moves until it contacts the housing to limit the moving position of the positioning block;

[0014] The movement of the transmission rod also drives the movement of the two support rods through the two bushings. When the two support rods move, they drive the movement of the two extrusion bars. When the two extrusion bars move, they both drive the slider to slide inside the chute through the connecting block, increasing the stability of the two extrusion bars during movement. When the two extrusion bars move, they both squeeze the rectangular rod to move downward through the inclined block, and at the same time squeeze the two return springs. Through the elastic force of the two return springs, the two rectangular rods have the ability to automatically reset. When the two rectangular rods move downward, they drive the two compression hoops to move downward to tightly fix the insulating medium;

[0015] (2) Then, the operator rotates the transmission rod by ° through the handwheel. When the transmission rod rotates, it drives the positioning block to rotate downward. When the positioning block rotates downward, it pushes the clamping rod through the inclined plane. When the clamping rod is pushed, it drives the extrusion disc and the pull rod to move, and at the same time squeezes the telescopic spring. When the pull rod moves, it slides along the inside of the lower sliding sleeve, improving the stability of the pull rod during movement. When the positioning block drives the card hole to rotate to the position of the clamping rod, the clamping rod will be pushed to move back and snap into the inside of the card hole under the elastic force of the telescopic spring for locking. Then, the operator reinstalls the connector on the housing, thus quickly completing the installation;

[0016] (3) It enables the internal cavity of this high-frequency millimeter-wave coaxial connector to quickly and conveniently fix multi-media materials, and has strong reliability, avoiding the loosening or falling off of multi-media materials after temperature shock and thermal cycling.
