Description
【Technical field】
A kind of thread tapping is the utility model is related to, more particularly to a kind of firm thread tapping of screens.
【Background technology】
Thread tapping, oneself carries out tapping while being screwed into, and to reach the purpose of oneself tapping, this screw is typically all
Tip, object to be screwed into is squeezed into facilitate, at present, common thread tapping is shot after target, and screens is insecure, is easily occurred
Loosen, cause the thread tapping for shooting target to be scrapped, failure hidden danger, most thread tapping shoots target difficult, the side of shooting
Formula is single.A kind of therefore, it is proposed that firm thread tapping of screens.
【Utility model content】
Main purpose of the present utility model is to provide a kind of screens firm thread tapping can effectively solve background technology
The problem of middle.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of firm thread tapping of screens, including countersunk head, attack post and lead screw, the lead screw top are provided with attack
Post, the attack column top are provided with turret head, and wrench faces are distributed with the turret head surrounding, and the turret head top surface is set
There is cross recess with rising as high as the banks, the lead screw surface is provided with external screw thread and internal thread, and the external threaded surface is provided with barb, described
Lead screw bottom is fixedly connected with countersunk head, and the countersunk head surface is provided with concave surface and convex surface, and the concave surface is provided with hangnail, described
Spacer is installed at the top of countersunk head, and the two is fixedly connected.
Further, the cross recess inside center is provided with fixing hole, and the fixing hole surrounding is provided with stator, and solid
Stator is fixedly connected with cross recess.
Further, the countersunk shape is cone, and the concave surface is placed in countersunk head surface with convex surface interval.
Further, the spacer is fixed at the top of the concave surface of countersunk head.
Compared with prior art, the utility model has the advantages that：A kind of firm thread tapping of screens, passes through
In screw surface, the use for the spacer installed at the top of barb and countersunk head is set so that thread tapping shoots extremely difficult taking-up after target,
Solve the conventional unstable problem of thread tapping screens, because countersunk shape changes, the setting of the concave surface and convex surface on countersunk head surface,
Accelerate thread tapping to shoot target, rational in infrastructure, practical function, be adapted to be widely popularized.

【Embodiment】
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to embodiment, the utility model is expanded on further.
As Figure 1-4, the firm thread tapping of a kind of screens, including countersunk head 8, attack post 3 and lead screw 4, the screw
The top of bar 4 is provided with attack post 3, and the top of attack post 3 is provided with turret head 1, and wrench faces 2 are distributed with the surrounding of turret head 1,
The top surface of turret head 1 is provided with cross recess 13 and rises as high as the banks 15, and the surface of lead screw 4 is provided with external screw thread 5 and internal thread 6,
The surface of external screw thread 5 is provided with barb 9, and the bottom of lead screw 4 is fixedly connected with countersunk head 8, and the surface of countersunk head 8 is provided with recessed
Face 10 and convex surface 11, the surface of concave surface 10 are provided with hangnail 12, and the top of countersunk head 8 is provided with spacer 7, and the two company of fixation
Connect.
Wherein, the inside center of cross recess 13 is provided with fixing hole 14, and the surrounding of fixing hole 14 is provided with stator 16,
And stator 16 is fixedly connected with cross recess 13.
Wherein, the countersunk head 8 is shaped as cone, and the concave surface 10 is placed in the surface of countersunk head 8 with the interval of convex surface 11.
Wherein, the spacer 7 is fixed on the top of concave surface 10 of countersunk head 8.
It should be noted that the utility model is a kind of firm thread tapping of screens, during work, thread tapping is directed at mesh
Mark, apply external force with hammer and drive lead screw 4 to decline in the top of turret head 1, attack post 3, countersunk head 8 is entered target, change cross
In the cross recess 13 for playing the insertion top surface of turret head 1, fixed by fixing hole 14 and stator 16, apply pressure and torsion,
Allow lead screw 4 to decline, after lead screw 4 drops to predeterminated target, remove cross and rise, the hangnail 12 on the convex surface 11 of countersunk head 8 is with sinking
The spacer 7 at first 8 top pours into, in target so that extremely difficult removal, the barb 9 on the external screw thread 5 on the surface of lead screw 4, revolving
Drag minimization when entering, barb 9 is caught in target when screwing out so that thread tapping is not easy to screw out.
