Description
Technical field
A kind of self-tapping screw is the utility model is related to, is suitable for small space or blind area portion more specifically to one kind
Position, need repeatedly and during convenient replacing accessory operation, the self-tapping screw that fastening wooden class accessory is used.
Background technology
At present, when carrying out terminal operation using the region of common wood screw (Fig. 1) for inconvenience, general use twists rod-type
Screw (Fig. 2).Twisting rod-type screw has the advantages of cheap, stubborn bar convenient material drawing, but there is also stubborn bar and screw fixation not
Surely, the shortcomings that bar insertion is difficult, is twisted in blind area operation, causes phenomenon of slipping out of the hand with screw fixation shakiness due to twisting bar, directly affects screw
Under attack ability, often initially will by hammering, could not generally reach self-tapping screw it is due under attack power, this all makes operation
Live terminal operation has difficulty in taking a step, increases many idle man-hours on foot.
Utility model content
Technical problem to be solved in the utility model is, there is provided a kind of self-tapping screw, the screw is not only cheap,
And without hammering, only with voluntarily precessing force enough just can be obtained manually.
In order to solve the above-mentioned technical problem, the utility model provides a kind of self-tapping screw, and it includes screw and stubborn, institute
State screw and be provided with screw head, follow block and screw rod, the follow block is fixedly arranged between the screw rod and screw head, and the top of the screw head is circle
Frustum, bottom are square body, and the stubborn handle is provided with dactylostyle and sleeve, and the sleeve is provided with the side for coordinating socket with the square body
Shape hole, the dactylostyle are fixedly arranged on the outer circumferential walls of the sleeve.
As the preferable scheme of the utility model, described stubborn be additionally provided with finger support, it is described finger support be fixedly arranged on the screw and
Twist between and form an overall structure.
As the preferable scheme of the utility model, the stubborn handle by the dactylostyle, refer to support and sleeve integral manufacturing form.
As the preferable scheme of the utility model, the screw is formed by the screw head, follow block and screw rod integral manufacturing.
Implement a kind of self-tapping screw of the present utility model, compared with prior art, have the advantages that：
The utility model is not only cheap, and without hammering, only with just obtaining enough voluntarily precessions manually
Power, overcome attacked under traditional self-tapping screw power deficiency, precession mode it is single caused by moment of torsion deficiency the shortcomings that, realize self tapping
Real " self tapping " function of screw；Meanwhile twist and the linkage with screw is designed using blind set mode, twist simplicity is inserted in, cause
Small space or the operation of blind area position also can easily operate screw precession operation, and precession mode can continuous precession with
It is easy to arbitrarily change between firmly orientation precession, makes operation field no longer because fastener performance issue is perplexed, order fastening is made
Industry no longer makes or have much ado, wastes man-hour.
Brief description of the drawings
In order to illustrate more clearly of the technical scheme of the utility model embodiment, the accompanying drawing of embodiment will be made below simple
Ground introduction.
Fig. 1 is the structural representation of common wood screw；
Fig. 2 is the structural representation for twisting rod-type screw；
Fig. 3 is the exploded view of self-tapping screw provided by the utility model.
In figure：1st, screw, 1-1. screw rods, 1-2. follow blocks, 1-3. screw heads；
2nd, handle, 2-1. dactylostyles are twisted, 2-2. refers to support, 2-3. sleeves.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in figure 3, preferred embodiment of the present utility model, a kind of self-tapping screw, it includes screw 1 and twisted 2, described
Screw 1 is provided with screw head 1-3, follow block 1-2 and screw rod 1-1, and the follow block 1-2 is fixedly arranged between the screw rod 1-1 and screw head 1-3,
The top of the screw head 1-3 is the frustum of a cone, and bottom is square body, described stubborn to be provided with dactylostyle 2-1 and sleeve 2-3, the sleeve 2
2-3 is provided with the square opening for coordinating socket with the square body, and the dactylostyle 2-1 is fixedly arranged on the outer circumferential walls of the sleeve 2-3.Its
In, it is described it is stubborn be additionally provided with finger support 2-2 2, the support 2-2 that refers to is fixedly arranged on the screw 1 and twisted the simultaneously integral knot of shape between 2
Structure.Preferably, it is described it is stubborn 2 by the dactylostyle 2-1, refer to support 2-2 and sleeve 2-3 be integrally cast；The screw 1 is by described
Screw head 1-3, follow block 1-2 and screw rod 1-1 integral manufacturings form.
It should be noted that being attacked under screw 1 and precession is by being provided with the sleeve 2-3 of square opening being set on 2 twisting
After being inserted in the screw head 1-3 of screw 1, by referring to, support 2-2 and dactylostyle 2-1 obtains down attacking power and torsion completion 1 overall precession of screw is straight
To by the follow block 1-2 stops of screw 1, so as to complete terminal operation.The screw head 1-3 of screw 1 is designed to circular upper part and square lower part entity, phase
Compared with stubborn rod-type screw cylindrical intermediate throughholes screw head form more resistant to hammering, be especially designed to cone type in end,
On the one hand enable to twist and 2 sleeve 2-3 is imported easily, realize blind set function, hammering on the other hand can be used as to be prevented square by face
Pullover is directly damaged by hammering and phenomenon can not be inserted in 2 by causing to twist；Refer to support 2-2 design, increase twist 2 it is whole
Body intensity, there is support using work(or force, make self-tapping screw obtain attacking power under abundance, realize real self tapping function.
Thus, a kind of self-tapping screw of the present utility model is implemented, it is not only cheap, and without hammering, only
With voluntarily precessing force enough just can be obtained manually, overcome and power deficiency is attacked under traditional self-tapping screw, precession mode is single causes
Moment of torsion deficiency the shortcomings that, realize self-tapping screw really " self tapping " function；Meanwhile twist and the linkage with screw is used blind set side
Formula designs, and twists simplicity is inserted in, causes also can easily operate screw precession operation in small space or the operation of blind area position, and
And precession mode in continuous precession and can be easy to arbitrarily change between firmly orientation precession, make operation field no longer because of fastener
Performance issue is perplexed, and is made terminal operation no longer make or have much ado, is wasted man-hour.
Above disclosed is only preferred embodiment of the present utility model, certainly can not be new to limit this practicality with this
The interest field of type, therefore the equivalent variations made according to present utility model application the scope of the claims, still belong to the utility model and covered
Scope.
