Further, form a convex tendon on the sidewall of described link, the locating notch that formation one and convex tendon are used in conjunction with in the described fixed block.By cooperating of convex tendon and locating notch, fixed block is positioned on the link.
Further, the cross section of described convex tendon is the trapezoidal of outer narrow inner width, and convex tendon is connected on the locating notch.
Further, a circle fillet is formed on the top of described steel pin, and the bottom of described link and fixed block all is formed for holding the locating slot of fillet, an end opening of locating slot, and fillet enters the locating slot from the locating slot opening.By being connected of fillet and locating slot, being connected between the bottom that makes link and fixed block and the steel pin top is more firm.
Further, described two occlusal cribs are and are symmetrical arranged, and the snap-in force that the crossbeam both sides are subject to equates structural stability.
Further, the afterbody of described screw is between the upper surface and crossbeam bottom surface of link, and the afterbody of this screw can be covered by crossbeam, and it is not exposed.
Further, described fixed block is connected with link by screw, and the afterbody of described screw is positioned on the outer side wall of fixed block, and this screw exposes, and also is the unique fastening piece that exposes of the utility model.
Further, the cross section of described crossbeam is " X " shape, and two footing lays respectively in two occlusal cribs, in the groove that the boss that forms between two occlusal cribs forms between two footing.Adopt the crossbeam of described shape, increased the area of contact that connects, form a very firm steel frame system.
Further, a side lower part inwall of described occlusal crib is a vertical surface, and upper inside wall is an inclined-plane, and the opposite side inwall also is an inclined-plane, and the bottom surface of occlusal crib is a horizontal plane, places the external frame of header portion of occlusal crib and the vallecular cavity form fit of occlusal crib.Adopt the occlusal crib of described shape to have interlock and the laterally effect of interlock.
The beneficial effect that the utlity model has: the split design by link and fixed block, install more conveniently, need only and install in the side of steel pin, need not under desktop, to install; The crossbeam of special shape and occlusal crib by the Placement of interlock, have increased the area of contact that connects, and form a very firm steel frame system; Almost can't see the screw or the screw that connect usefulness after the installation, improved the overall quality of product.
