A kind of screw conducting portion is disposed with the screw of guide ring
The utility model is related to screw manufacturing technology fields, and guide ring is disposed with more particularly to a kind of screw conducting portion
The screw of script is easy to happen inclination when squeezing into installation site, and tilting drivescrew can so that screw is tired to tooth
Hardly possible is so that sliding dental phenomenon occurs in screw, and in order to solve this problem, a kind of new bolt structure of redesign is that have very much
It is necessary.
The technical problem to be solved by the utility model is to provide the screw that a kind of screw conducting portion is disposed with guide ring, tools
Have it is simple in structure, convenient for production, by designing guide ring, the installation effectiveness etc. that can effectively avoid sliding dental phenomenon, improve screw
Technical solution adopted by the utility model to solve its technical problems is：It a kind of screw conducting portion is provided is disposed with and lead
To the screw of ring, including screw conducting portion, guide ring and screw bulb end, spiral shell is disposed on described screw conducting portion one end
Bulb end is followed closely, the other end is connected by end interconnecting piece with the screw head of a nail, the screw conducting portion and screw bulb end
Between outer ring on be disposed with guide ring, the screw conducting portion outer ring is disposed with screw thread, and the diameter of the guide ring is small
In major diameter of thread, assembling process, screw carries out pre- directing in rotary course by guide ring and nut thread, to for after
Continuous thread provides help to tooth.
One end of the screw bulb end is connected with screw conducting portion, and the other end uses flush configuration.
The end interconnecting piece is disposed with a ring annular groove at the screw head of a nail, and washer, institute are equipped on annular groove
It is cone structure that the washer stated uses planar structure, the washer other end close to screw conducting portion side.
Advantageous effect：The utility model is related to the screw that a kind of screw conducting portion is disposed with guide ring, have it is simple in structure,
The features such as convenient for production, by designing guide ring, can effectively avoid the installation effectiveness of sliding dental phenomenon, raising screw.
