Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further illustrated.
As shown in Figure 1, orthopaedics extenal fixation shank fixation clamp of the present utility model, comprise bolt 3, and the first intermediate plate 5 set gradually, second intermediate plate 6, 3rd intermediate plate 7 and the 4th intermediate plate 8, bolt 3 comprises bolt head 1 and shank of bolt 2, shank of bolt 2 is successively through the first intermediate plate 5, second intermediate plate 6 and the 3rd intermediate plate 7, and shank of bolt 2 is threaded with the 4th intermediate plate 8, one end of first intermediate plate 5 is provided with the first half grooves, one end of second intermediate plate 6 is provided with the second half grooves, the first half grooves and the second half grooves form the first clip slot 11 jointly, one end of 3rd intermediate plate 7 is provided with the 3 half groove, one end of 4th intermediate plate 8 is provided with the 4 half groove, 3 half groove and the 4 half groove form the second clip slot 12 jointly, when first clip slot 11 is for folder needle tray, the second clip slot 12 is clamping bar groove, when first clip slot 11 is clamping bar groove, the second clip slot 12 is folder needle tray, the spring 9 be socketed on shank of bolt is provided with between second intermediate plate 6 and the 3rd intermediate plate 7.Adopt said structure, this shank fixation clamp is provided with a folder needle tray and a clamping bar groove.Folder needle tray is that clamping bar groove is for rod like parts such as fixed connecting rods for eedles such as fixation and pull bonl pins.During use, the elastic force of spring 9 can realize the pre-clamping of each intermediate plate, corresponding fine steel needle and connecting rod can be blocked fast by first clip slot 11 at spring 9 two ends and the second clip slot 12, after good fine steel needle to be adjusted and the angle needed for connecting rod, bolt 3 be tightened and can be located.
When above-mentioned spring 9 is installed, can directly be resisted against between the second intermediate plate 6 and the 3rd intermediate plate 7.Preferably adopt following structure: described second intermediate plate 6 is provided with the first counterbore for holding spring 9, described 3rd intermediate plate 7 is provided with the second counterbore for holding spring 9.Adopt said structure, the opposite face of the second intermediate plate 6 and the 3rd intermediate plate 7 can contact with each other, make compact conformation, also anti-rotation structure can be set on opposite sides simultaneously, object is after the relative angle adjustment of the second intermediate plate 6 and the 3rd intermediate plate 7, prevents them from use unnecessary rotation occurring again.For this reason, on the basis of the above, as shown in Figure 1, described second intermediate plate 6 is provided with first surface tooth the 13, three intermediate plate 7 towards the one side of the 3rd intermediate plate 7 and the one side of the second intermediate plate 6 is provided with second tooth 10 engaged with first surface tooth.When first surface tooth 13 and second tooth 10 engage, the rotation of the second intermediate plate 6 and the 3rd intermediate plate 7 is hindered.
For the ease of finely tuning the first intermediate plate 5, between described first intermediate plate 5 and shank of bolt 2, be provided with spherical washer 4.The first intermediate plate 5 can be allowed to tilt by a small margin by spherical washer 4.
In order on the basis of the above, be convenient to the first intermediate plate 5 and the second intermediate plate 6 and combine fast and accurately and form above-mentioned first clip slot 11, as shown in Figure 1, described first intermediate plate 5 is provided with corresponding projection and groove with between the second intermediate plate 6.In like manner, as shown in Figure 1, described 3rd intermediate plate 7 is provided with corresponding projection and groove with between the 4th intermediate plate 8.Above-mentioned projection and groove can be arranged on the below of corresponding clip slot.Protruding and corresponding groove plays the effect of location, prevents from misplacing between the intermediate plate of use in pairs.
Connected mode between above-mentioned shank of bolt and the 4th intermediate plate has multiple, and for the ease of dismounting and installation, the inside of the 4th intermediate plate 8 is provided with the swivel nut be connected with bolt thread.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
