It is connect using limited block with nut, the area of limited block is larger, connect with nut, and the nut of two sides gives area
Biggish limited block can play better firm effect, and the rank street area of inserted link is smaller, cooperate with mounting hole, and first can be made to consolidate
Cover half block and the second fixed module use lesser volume, and lesser equipment is convenient for finger use.
A kind of optimal technical scheme, the length of the threaded rod are greater than the overall length of the first fixed module and the second fixed module
Degree.
I.e. the first fixed module and the second fixed module are same when first fixed module and the second fixed module are arranged in parallel
In one plane, the use length of threaded rod be it is longest, the length of threaded rod is at least solid with the first fixed module and second at this time
The total length of cover half block is equal.
A kind of optimal technical scheme, the clamp device include fastening bolt, and the fastening bolt is connect with fixed module,
The fixed module is provided with bolt hole above pin hole, and the bolt hole is connect with pin hole.
It beats bolt hole above pin hole to pass through for fastening bolt, pin hole is connect with bolt hole, and bolt tightens pin hole under needle
Pressure plays fixed function.
By adopting the above-described technical solution, compared with prior art, the utility model has the advantages that: it can be right after surgery
Finger is fixed, and can adjust finger curvature in convalescence, helps the post-operative recovery of patients fingers.
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
