Problems solved by technology
This kind of expansion locking structure is only for interference locking at the head of the inner jaw (at the locking buckle), and many parts of the inner jaw are clearance fit in the outer jaw, which is easy to cause it to not fit with the sternum, resulting in deformation and detachment. open
When the inner claw hook plate and the outer claw hook plate are adjusted to the maximum distance, the locking position is at the extreme end of the inner claw hook plate and the outer claw hook plate. This locking structure makes the inner claw hook plate and the outer claw hook plate easy to Deformation and disengagement, low reliability; the inner and outer claws are forced to be inserted and locked, and when the inner and outer claws produce yield force, there are defects that it is difficult to open and hinder rescue, and cannot be made of medical TA2 / TA3 materials
