Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, a kind of bone External fixation screw bar cramp device, including clamping bar block 1, folder needle block 2 and connecting screw
3, the clamping bar block 1 and the folder needle block 2 are linked together by the connecting screw 3, and the clamping bar block 1 is provided with support rod
Card hole 15 and clamping bar elastic force hole 14, clamping bar elastic force hole 14 and 15 interconnecting piece of support rod card hole are arranged to hatch frame；It is described
Folder needle block 2 is provided with spicule card hole 25 and folder needle elastic force hole 24, and the spicule card hole is arranged to folder 24 interconnecting piece of needle elastic force hole
Hatch frame.
The clamping bar block 1 and folder needle block 2 are integral type hatch frame, guarantee clamping bar block 1 and folder needle block 2 in connecting screw 3
When connection, simultaneously shape does not occur for clamping bar block 1 and folder needle block 2；Clamping bar block 1 is provided with clamping bar elastic force hole 14, when support rod card is to support
When bar card hole 15, two parts up and down of clamping bar block 1 are opened, support rod smoothly sticks into support rod card hole 15, described
The diameter of support rod is more bigger than the diameter of the support rod card hole 15, and the extended distance of the support rod card hole 15 is than support
The diameter of bar is smaller, can guarantee support rod clamping tightly in support rod card hole 15 in this way, not be subjected to displacement；Press from both sides needle block
2 are provided with folder needle elastic force hole 24, when spicule card is to spicule card hole 25, two parts up and down of folder needle block 2 are opened, bone
Needle smoothly sticks into spicule card hole 25, and the diameter of the spicule is more bigger than the diameter of the spicule card hole 25, the spicule card
The extended distance in hole 25 is more smaller than the diameter of spicule, can guarantee spicule clamping tightly in spicule card hole in this way, no
It is subjected to displacement, rehabilitation efficacy is more preferable.
On the basis of the above, as shown in figure 3, the folder needle block 2 is provided with boss 21 close to the clamping bar block 1 on one side,
The folder needle block 2 is provided with nut 22 far from the clamping bar block 1 on one side；As shown in figure 4, the clamping bar block 1 is close to the folder
Needle block 2 is provided with the groove cooperated with boss 21 on one side.The groove for designing boss 21 and cooperating with boss 21, when in use only
