Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Refer to Fig. 1 to Fig. 4, ring of the present invention rod combination exterior fixing rack, comprises six roots of sensation screw 1, two arcsShape side plate 2, some metal bone needles 3 (in the present embodiment being 6), two vertical columns 4, slide posts 5, adjustJoint nut 6, screw connection 7, contiguous block 8 and some lock screws 9, wherein:
Two arc side plates 2 divide abreast and stand in both sides, have penetrating deep-slotted chip breaker 22 in the middle of arc side plate 2,One side of arc side plate 2 is provided with scale 21 along arc length, and every two adjacent graduation marks are apart from 1 millimeter;
Vertical columns 4 is column type, and centre has cannelure 43, and two ends are equipped with and snap in first of deep-slotted chip breaker 22Boss 41, the first boss 41 radially have the first screw hole 410; By screw 1 being screwed in to the first screw hole 410,Make two vertical columns 4 be separately fixed at the two ends of two deep-slotted chip breakers 22 of two arc side plates 2, thereby connectBe connected into a framework, as shown in Figure 1;
On vertical columns 4, have at least two and hold the first circular hole 42 of vertically passing of metal bone needles 3, also have withEach first circular hole 42 is corresponding and orthogonal the first locking screw holes 44 one by one, and lock screw 9 screws in the first lockTight screw 44 is by fixing metal bone needle 3, and obviously, the quantity of lock screw 9 is consistent with the quantity of metal bone needle 3,On metal bone needle 3, have and hold the hole that lock screw 9 penetrates;
Slide post 5 two ends are equipped with the second boss 51 that snaps in deep-slotted chip breaker 22, and this second boss 51 radially hasThe second screw hole 510; By screw 1 being screwed in to the second screw hole 510, make the slide post 5 can be along twoTwo deep-slotted chip breakers 22 of arc side plate 2 slide;
On slide post 5, have at least two and hold the second circular hole 52 of vertically passing of metal bone needles 3, also have with respectivelyIndividual the second circular hole 52 is corresponding and orthogonal the second locking screw holes (not shown) one by one, and lock screw 9 revolvesEnter the second locking screw holes by fixing metal bone needle 3;
