Detailed Description
Example 1
As shown in fig. 1-4, the present invention will be further explained with reference to the accompanying drawings: the femoral stem knocking holder comprises a knocking head 1, wherein the knocking head 1 is connected with one end of a holding part 2, the other end of the holding part 2 is connected with a connecting rod 3,
the head of the connecting rod 3 is conical; connecting rod 3 one side detachable is equipped with elasticity peg 4, and the connecting rod 3 other end is equipped with clamp 5, clamp 5 one side is equipped with the recess, arrange in the recess when couple 7 pushes down. One end of the elastic hanging rod 4 is provided with a hook 7, the other end of the elastic hanging rod 4 is clamped into the connecting rod 3, and the elastic hanging rod 4 is provided with an elastic sheet 6.
One end of the femoral stem 8 is provided with a circular groove fixed with the head of the connecting rod 3, and a T-shaped groove matched with the hook is formed in the circular groove.
During the use, beat the femoral stem and beat in the circular recess of holder squeeze into femoral stem 8, squeeze into back couple 7 automatic card and catch on in T type inslot and hold and fix, after squeezing into the femoral stem, press shell fragment 6, push down 0.3 with elasticity peg 4, can realize the separation from in couple 7 and T type groove, conveniently beat the holder with the femoral stem and take out.
The head of the utility model is unthreaded, the risk of thread striking deformation is avoided, the whole body adopts a solid rod design, and the strength and toughness are good; the hook 7 is in non-fixed connection with the femoral stem 8, the hook 7 is not stressed when in striking, and the elastic hanging rod 4 can be detached and is convenient to process and clean.
The femoral stem 8 is different from the original femoral stem in that a groove is added for connecting the hook 7, and the processing is completed by a T-shaped milling cutter when in use.
