[0018] The features and exemplary embodiments of each aspect of the utility model will be described in detail below, in order to make the purpose, technical scheme and advantages of the utility model more clear and clear, the following is combined with the specific embodiment, and the utility model is further described in detail. For those skilled in the art, the utility model can be implemented without some of these specific details. The following description of the embodiment is only to provide a better understanding of the utility model by showing the examples of the utility model.

[0019] As Figure 1 The utility model provides a kind of sharp tail screw technical scheme of quick attack, as shown in the figure, including screw body 1, on screw body 1, along the length direction of screw body 1 integrally formed and set working thread 2, while, on working thread 2, recess one 3 is opened along horizontal direction, a plurality of recess one 3 exports for wood chip, prevent wood and cause cracking due to space extrusion.

[0020] In this embodiment, the screw body 1 includes a screw rod 4, and a sharp portion 5 is integrally formed at one end of the screw rod 4. The sharp portion 5 increases the pressure between the screw rod 4 and the installation position, and facilitates the screw body 1 to enter the installation position.

[0021] In this embodiment, a plurality of protrusions 9 are integrally formed on the circumferential side of the sharp portion 5. The plurality of protrusions 9 are integrally formed with the sharp portion 5, and are arranged along the circumferential direction of the sharp portion 5. The protrusions 9 are located between two adjacent working threads 2. The protrusions 9 are arranged to enable the screw to be quickly driven into wood under the same pressure, and then to speed up the worker's screwing speed.

[0022] As shown in Figure 2 A processing die includes a static block 11 and a dynamic block. The static block 11 and the dynamic block have the same structure. The dynamic block is located directly above the static block 11. A screw blank is placed between the static block 11 and the dynamic block to generate threads and complete the thread processing of the screw. A plurality of V-shaped grooves I 13 are formed on the top surface of the static block 11 along the length direction. The plurality of V-shaped grooves I 13 are arranged along the length direction of the static block 11. The plurality of V-shaped grooves I 13 are used to process the inclined thread 10 on the screw. The V-shaped grooves I 13 are used to plastically deform the screw blank by extrusion, extruding the material at the bottom of the thread to the tip of the thread to form the thread.

[0023] In this embodiment, a plurality of V-shaped grooves II 14 are formed on the top surface of the static block 11 along the width direction. The plurality of V-shaped grooves II 14 are arranged along the width direction of the static block 11. The working principle of the V-shaped grooves II 14 is the same as that of the V-shaped grooves I 13. The V-shaped grooves II 14 are used to process threads by extrusion. The thread angle of the working thread 2 is different from that of the inclined thread 10, such as the thread depth and the thread angle. In order to prevent slipping due to the length of the screw being too long and the processing speed being too fast during screw processing, vertical anti-skid teeth are added on the right side. Sand blasting can also be used to further increase the friction.

[0024] In this embodiment, protrusions II are arranged on the top surface of the static block 11. The protrusions II are used to process the groove I 3. The number of the protrusions II can be designed according to actual conditions.

[0025] The top surface of the static block 11 is provided with a groove III 15, which is in communication with the plurality of V-shaped grooves II 14. The top surface of the static block 11 is provided with a groove II 16 along the length direction of the static block 11. The groove II 16 is in communication with the V-shaped grooves II 14. The groove II 16 is used to process the protrusions 9.
