Description
Technical field
The present invention relates to a kind of screw, in particular to one kind can be installed on metope after pre- subdrilling digging preparation hole
Setscrew structure.
Background technique
Current existing setscrew mainly includes sleeve, the screw rod that can penetrate the casing and a screw lock at this
Nut on screw rod, the ora terminalis of the screw rod are formed with an enlarged end, are wearing the preparation hole being drilled in advance in wall into one
Afterwards, by turn, the nut is displaced outwardly the screw rod, and struts the casing shoe by the enlarged end of screw rod and push up
It is against in the preparation hole, is capable of fixing setscrew in the preparation hole.
However above-mentioned setscrew needs to use the tools such as drill bit to bore in advance in locking position in advance before use
Preparation hole is dug out, and the aperture of the preparation hole need to be with the outer diameter and length of cooperation setscrew, can not be excessive or too small, because
This is rather troublesome and time-consuming on applying.
Further, since drill bit can constantly wear atrophy and attenuate because bore operation is executed, in actual job
In, drill bit needs constantly to eliminate trade-in, in case the aperture for generating preparation hole is too small and causes setscrew that can not insert in the hole
Or it is stuck in preparation hole.
It needs just setscrew be made completely to enter preparation hole with hammer or the percussion of hard object when finally putting setscrew into,
But often because the limited of angle causes percussion to be not easy, generation applies unstable quality or imperfect.
In view of this, how above-mentioned missing to be forgone, as where the present inventor's technical difficulties to be solved；
Therefore, the present inventor is concentrated on studies based on the experience for being engaged in relevant industry for many years through taking great pains to attain one's goal for many years, studies improvement, finally
Success, which is researched and developed, completes the present invention.

One word groove or a cross recess；
One body is internally provided with internal screw thread, and the both ends of the body are connected to outside, which includes a clamping part, a card
Tug portion and an enlarged portion, the clamping part side opposite with the blocking part are combined with each other, and the outer diameter of the clamping part is greater than the clip
Portion, blocking part outside are equipped with multiple clamping pieces, which is one of the forming with the enlarged portion, which is equipped with more
A grooving, each grooving extend to the end face of the enlarged portion, the cylinder with the internal screw-thread screw of external screw thread and the body, the body with
The clamping piece clip is made in an object by a tool in conjunction with the word groove or the cross recess with rotating the cylinder
The enlarged portion of the second end towards the body is mobile, which expand the enlarged portion outwardly, the body is made to be fixed on this
In object.
Preferably, the clamping part of the body of the screw structural is polygon.
Preferably, the clamping piece of the body of the screw structural is external screw thread.
The main purpose of screw structural of the present invention is: being equipped with external screw thread on the outside of body, enables the closer stabilization of body
In conjunction with object.
