When the problem of fixed-direction of off-design is susceptible to during drivescrew.
Utility model content
The utility model to solve the above-mentioned problems, devises a kind of casing type pressure peg, the peg apply simultaneously with
The both sides of fracture site can prevent trip bolt unilateral side from fixing the problem of loosening, while the peg fit inside Kirschner wire
Fracture site is squeezed into positioning, peg can be effectively prevent the problem of fixed-direction of off-design occur during squeezing into, the peg
Anchoring rib can securely be embedded in fracture site, it is antitorque, non-skid property is more preferable.
In order to achieve the above technical purposes, reach above-mentioned technique effect, the utility model is real by the following technical programs
Existing：
A kind of casing type pressure peg, including the first rivet nut, the second rivet nut and guide sleeve, the first rivet nut and the second rivet nut
It is hollow structure with guide sleeve, the first rivet nut and the flexible connection of the second rivet nut, the tail portion of the second rivet nut are equipped with gasket, and second
Anchoring rib is equipped at the interface of rivet nut and gasket, guide sleeve is put inside the rivet nut with the second rivet nut.
Further, the head of a nail of first rivet nut is the interior hexagonal flower-shape head of a nail.
Further, the connection type of first rivet nut and the second rivet nut is to be threadedly coupled.
Further, the equal length of the guide sleeve and the second rivet nut.
Further, the central axes of first rivet nut, the second rivet nut and guide sleeve are on same axis.
The utility model has the beneficial effects that：The peg applies the both sides with fracture site simultaneously, can prevent trip bolt
The problem of loosening, is fixed in unilateral side, while fracture site is squeezed into peg fit inside Kirschner wire positioning, can effectively prevent bolt
There is the problem of fixed-direction of off-design during squeezing into nail, and the anchoring rib of the peg can securely be embedded in fractures
Position, it is antitorque, non-skid property is more preferable.
Certainly, any product for implementing the utility model does not necessarily require achieving all the advantages described above at the same time.
