is all hinged on front jointed shaft 25, the rear end of top rear stay plate 15 and bottom rear stay plate 16 is hinged and connected to respectively on core bar sleeve pipe 8, in the middle of top, between the middle fagging 12 in fagging 9 and bottom and core bar 18, be respectively arranged with top strut 14 and bottom strut 13, one end of top strut 14 is hinged and connected to behind top on jointed shaft 22, the other end of top strut 14 is hinged and connected on core bar 18, one end of bottom strut 13 is hinged and connected to behind bottom on jointed shaft 24, the other end of bottom strut 13 is hinged and connected on core bar 18, before described top, in the middle of the top of the size for connection of fagging 10, top rear stay plate 15 and top strut 14 after guaranteeing to strut, fagging 9 is parallel with core bar 8, before bottom, the bottom strut 13 of the size for connection of fagging 11, bottom rear stay plate 16 and bottom strut 13 after guaranteeing to strut is parallel with core bar 8, and the top strut 14 after strutting in the present embodiment to the distance of core bar 18 is less than bottom strut 13 to the distance of core bar 18, the rear end of core bar sleeve pipe 18 is fixedly connected on shank housing 3, the rear end of core bar 18 stretches in shank housing 3 and is connected with the front end of coupling assembling in shank housing 3, the rear end of coupling assembling is connected with handle connecting rod 1, between handle connecting rod 1 and shank housing 3, threaded engagement is connected, turning handle connecting rod 1 can promote coupling assembling and core bar 18 moves forward or backward, make in the middle of top fagging 12 in the middle of fagging 9 and bottom be separated from each other or mutually draw close, thereby make that top fagging assembly 19 and bottom fagging assembly 20 are upper and lower to be strutted or mutually closed.In the present embodiment, the structure of coupling assembling, with and comprise with the concrete syndeton of handle connecting rod 1 and core bar 18: interior shaft coupling piece 4 and core bar joint pin 6, the rear end of interior shaft coupling piece 4 is provided with the rear end installation cavity 42 of collar 41 after oral area band, the front end of interior shaft coupling piece 4 is provided with the front end installation cavity 44 of the front collar 43 of oral area band, the head of handle connecting rod 1 is provided with projection 101, on the handle connecting rod 1 of projection 101 rear sides, be provided with draw-in groove 102, the projection 101 of handle connecting rod 1 stretches in the rear end installation cavity 42 of interior shaft coupling piece 4, and in the draw-in groove 102 of rear collar 41 blocks on interior shaft coupling piece 4 on handle connecting rod 1, thereby handle connecting rod connecting rod 1 can be separated in the interior rotation of rear end installation cavity 42 with rear end installation cavity 42, the rear end of core bar 18 is fixedly connected on the front end of core bar joint pin 6, on the rear end step of core bar joint pin 6, interlock is provided with the spring collar 61 with spring card slot 611, inwardly pressing spring collar 61 can make to stretch in the front end installation cavity 44 of interior shaft coupling piece 4 together with the rear end of core bar joint pin 6 and the rear end of Spring Card certificate 61, spring collar after unclamping 61 outwards recovers distortion and makes the tight block of front collar 43 on front end installation cavity 44 in spring card slot 611, thereby the rear end of core bar joint pin 6 is connected with interior shaft coupling piece 4.In order to prevent that interior shaft coupling piece 4 is in the interior rotation of shank housing 3, on the outer wall of interior shaft coupling piece 4, be provided with the fin ring 46 of spacing draw-in groove, spacing draw-in groove active card on fin ring 46 is contained on spacing slide rail 31, and described spacing slide rail 31 is arranged on the inwall of shank housing 1 along the moving direction of core bar 18.
Operation principle is as follows: during original state, top fagging assembly 19 and bottom fagging assembly 20 are in mutual closure state, now one hold shank housing 3, proficiency turning handle connecting rod 1, core bar 18 is moved backward with respect to shank housing 3, thereby fagging 11 before fagging before top 10 and bottom is made progress respectively, lower both sides strut, thereby drive top strut 14 and top rear stay plate 15 upwards to strut gradually, drive bottom strut 13 and bottom rear stay plate 16 to strut downwards simultaneously, in the middle of top, in the middle of fagging 9 and bottom, fagging 12 is just softened respectively like this, in actual mechanical process, can be according to different needs, by turning handle connecting rod 1, they are adjusted to and differently strut height, make them be asymmetric softened state.Above-mentioned expanding structure is stable and strut great efforts, pathology vertebral body effectively can be strutted to correcting height, and because strutting of top strut 14 is highly less than strutting highly of bottom strut 13, therefore, the strutting of highly highly not symmetrical with strutting of lower fagging assembly 20 and top fagging assembly 19 that strut of top fagging assembly 19 is highly less than strutting highly of bottom fagging assembly 20, strutting so asymmetrically mode can more effectively strut pathology vertebral body, and is applicable to how complicated pathology vertebral body position.Reverse rotation handle connecting rod 1 can make top fagging assembly 19 and bottom fagging assembly 20 recover mutual closure state.
