Indent is provided with arc groove and forms 2 additional cutting edges on cusped edge, and the array of helical arrangement is provided on the shank
Scutum connected in star, the Scutum connected in star are spirally extended to bottom from shank outer circle top down, and the Scutum connected in star includes
Intermediate fusiformis slot and swallow tail shaped slot, the swallow tail shaped slot are symmetricly set on intermediate fusiformis slot both sides, the rotation connection handle setting
In the bottom of shank.
In a preferred embodiment of the present invention, the quantity of the Scutum connected in star is at least one.
In a preferred embodiment of the present invention, the drill-bit type syringe needle is welded at the top of shank.
In a preferred embodiment of the present invention, the rotation connection handle, drill-bit type syringe needle and shank are integrated steel knot
Structure.
In a preferred embodiment of the present invention, the rotation connection handle is square platy structure.
In a preferred embodiment of the present invention, the shank is hollow-core construction or solid construction.
In a preferred embodiment of the present invention, the quantity of the cusped edge is 4.
The beneficial effects of the invention are as follows：The thick steel needle with Scutum connected in star that a kind of multiple-cutting-edge that the present invention points out bores certainly,
Drill-bit type syringe needle especially is used, the structure of 4 sharp 12 swords can be formed, it is more convenient to drill on sclerotin, reduces and skids and partially
Oblique problem greatly improves the precision of working efficiency and fracture fixation, and is conducive to bone using Scutum connected in star and considers to be worth doing to form interior tenon,
Not only it can facilitate the growth of sclerotin, but also the fixation of shank can be reinforced, and improved the hold of thick steel needle and reduce reset loss problem.
Description of the drawings
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing, wherein：
Fig. 1 is a kind of structural schematic diagram of the multiple-cutting-edge of the present invention from one preferred embodiment of thick steel needle with Scutum connected in star bored.
Specific implementation mode
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
All other embodiment that technical staff is obtained without making creative work belongs to the model that the present invention protects
It encloses.
Referring to Fig. 1, the embodiment of the present invention includes：
A kind of thick steel needle with Scutum connected in star that multiple-cutting-edge bores certainly, including：It is rotatablely connected handle 1, drill-bit type syringe needle 3 and shank 2,
The drill-bit type syringe needle 3 is arranged at the top of shank 2, and the drill-bit type syringe needle 3 is polygonal pyramid body, polygonal pyramid body surface face from
Top is oblique to be arranged with 4 cusped edges 31, and indent is provided with arc groove 32 and forms 2 additional cuttings on every cusped edge 31
Sword forms the structure of 4 sharp 12 swords, reduces cutting force, and operation is more laborsaving, and borehole stability is high, and speed is fast, is not easy partially
Tiltedly, positional precision is high.
It is provided with the array Scutum connected in star 4 of helical arrangement on the shank 2, the Scutum connected in star is from 2 outer circle of shank
Top down interval is spirally extended to bottom, and the Scutum connected in star includes intermediate fusiformis slot 41 and swallow tail shaped slot 42, the swallow
Tail shape slot 42 is symmetricly set on intermediate 41 both sides of fusiformis slot, and intermediate fusiformis slot 41 and the angle of 2 central shaft of shank are 20 °.
The rotation connection handle 1 is arranged in the bottom of shank 2, and the rotation connection handle 1 is square platy structure, square plate
The convenient connection with rotational driving device of rotation connection handle 1 of shape structure, avoids skidding, the shank 2 be hollow-core construction or
Solid construction, hollow-core construction from heavy and light, it is at low cost, and the structure of solid construction is more secured, it is applied widely.
The Scutum connected in star imitates Patterns of Placoid Scales of Sharks structure, according to law of minimum resistance and plasticity in material pressure process principle
The Volume conservation law of deformation, the sclerotin cut after drilling are flowed from apex to both sides, are accumulated and are held at Scutum connected in star
