The outside of wedging ring described in the utility model also is provided with the lengthening reset sleeve, and it is arranged with the steel ball locating slot by the front end of steel ball location and installation at wedging ring on lengthening reseting sleeve barrel, steel ball, spring is housed in it, and fixes with plug.
Gripping sleeve tube wall described in the utility model is provided with the open slot to open front, and front inner wall is provided with the screw positioning convex.
Front hand grip described in the utility model, back handle inboard are respectively equipped with intilted support spring sheet, and two spring leafs upper end is inconsistent.
The lower end of front hand grip described in the utility model, back handle also is provided with connection tooth button and the tooth bar that matches.
This utility model reduction forceps is a gun type of gas burner, hold fixed handle, front hand grip drives its hinged promotion axostylus axostyle in upper end and moves forward, the wedging ring compression that front end is provided with clamps telescopic front opening, make the various bone screw that its clamping is to be positioned, reset, then pass the plug screw channel of reduction forceps gripping sleeve, plug screw is screwed in screw head with the plug screw bottle opener.Against existing technologies, it is simple in structure, and is easy for operation, and support force is strong, is used for location such as screw, pressure bar, resets reliably, is difficult for becoming flexible, and is applicable to the various bone screw of spinal operation location, the usefulness that resets, applied widely.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the another kind of embodiment of this utility model.
1. lengthening reset sleeve among the figure, 2. wedging ring, 3. gripping sleeve, 4. axle sleeve, 5. promotion axostylus axostyle, 6. bearing pin, 7. bearing pin, 8. support spring sheet, 9. support spring sheet, 10. front hand grip, 11. back handles, 12. tooth buttons, 13. tooth bar, 14. steel balls, 15. springs, 16. plugs, 17. open slots, 18. projectioies.
The specific embodiment
From Fig. 1, Fig. 2 as can be seen, a kind of rifle formula of this utility model reduction forceps, the gun type of gas burner that it is made up of handle portion and axle sleeve type clamping part, handle portion is formed by bearing pin 7 cross-articulation by front hand grip 10, back handle 11, the upper end of front hand grip 10 promotes axostylus axostyle 5 front ends and is provided with wedging ring 2 by the bearing pin 6 hinged promotion axostylus axostyles 5 that are provided with level; The upper end of back handle 11 is provided with the axle sleeve 4 of level, promotion axostylus axostyle 5 is positioned at it and can moves forward and backward along it, the front end of axle sleeve 4 is provided with elasticity gripping sleeve 3, gripping sleeve 3 is provided with through hole, be the channel of plug screw and plug screw bottle opener, can plug screw be screwed in screw head with the plug screw through hole that the plug screw bottle opener passes gripping sleeve 3.Gripping sleeve 3 walls described in the utility model are provided with the open slot 17 to open front, so that keep certain elasticity, front inner wall is provided with screw positioning convex 18, are used for and the slotted eye such as groove that lifts of bone screw head cooperates clamping and positioning.The wedging ring 2 that promotes axostylus axostyle 5 front ends is enclosed within gripping sleeve 3 outsides, can move forward and backward under the drive that promotes axostylus axostyle 5, and the front opening of elasticity of compression gripping sleeve 3 makes its pinching screw, the screw of locating, reset.The fixed reset that is specially adapted to the short-tail screw of said structure, wedging ring 2 also has the effect of pressure bar.
Fig. 2 is the structural representation of the another kind of embodiment of this utility model.As can be seen from Figure 2, the outside of wedging ring 2 described in the utility model also is provided with lengthening reset sleeve 1, and it is arranged with the steel ball locating slot by the front end of steel ball 14 location and installation at wedging ring 2 on lengthening reset sleeve 1 wall, steel ball 14, spring 15 are housed in it, and fixing with plug 16.Lengthening reset sleeve 1 can move forward under the drive that promotes axostylus axostyle 5 and wedging ring 2, and the front opening of elasticity of compression gripping sleeve 3 makes its pinching screw, the screw of locating, reset.Installing and using of reset sleeve 1 of lengthening can be used for the long-tail screw is carried out fixed reset, and the reset sleeve that extends here 1 also has the effect of pressure bar.
It is inconsistent that front hand grip 10 described in the utility model, back handle 11 inboards are respectively equipped with intilted support spring sheet 8,9, two spring leafs 8,9 upper ends.Like this can be behind fixed reset, wedging ring 2 retreats automatically, and gripping sleeve 3 front ends open automatically, unclamp the screw of clamping.
