Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and examples:

Embodiment 1: As shown in Figures 1 to 4, a tattoo needle of a tattoo instrument includes a body 1, an upward self-returning acupuncture component 2 is provided in the body, and a third needle is provided on the top of the body. A mating end 3. A second mating end 4 is provided on the outer surface of the first mating end. The outer diameter of the second mating end is smaller than the outer diameter of the top of the body. The outer surface of the second mating end is provided with a second mating end 3. Second external thread 5. In the present invention, the second butt end can be disposed on the outer surface of the first butt end, or the second butt end can be disposed on the bottom outer surface of the first butt end, or the second butt end can be disposed on the top outer surface of the first butt end. . In this embodiment, the second butt end is located on the bottom outer surface of the first butt end.

As shown in Figures 1 and 3, a through hole 101 is provided in the middle of the body. The middle part of the acupuncture component is moved and inserted into the through hole. A relief hole 102 is provided in the middle of the through hole. The diameter of the relief hole is larger than the diameter of the through hole. An annular bump 103 is provided on the outer surface of the middle part of the acupuncture component. The annular bump is arranged in the relief hole. A spring 104 is set in the middle of the acupuncture component. The bottom of the spring is against the bottom surface of the relief hole, and the top is against the annular On the bottom of the bump, the spring pushes the annular bump and the acupuncture component upward to self-reset. When the acupuncture component is pushed downward, the spring will be compressed, causing the acupuncture component to move downward. When the downward thrust of the acupuncture component is released, the spring will automatically recover and push the acupuncture component upward to realize upward self-return.

In this embodiment, the main body will be connected to the operating handle 6, and a driving mechanism will be provided in the operating handle to drive the needle punching component to extend to achieve tattoo work. When the operating handle is connected to the body, in the previous structure, only the first docking end is connected to the operating handle to form a primary fastening structure. However, in this structure, the primary fastening effect is not good enough, and the tattoo instrument Long-term high-vibration work can easily cause the fastening between the tattoo needle and the operating handle to loosen, resulting in poor tattoo accuracy, or the tattoo needle may detach from the operating handle during the tattooing process, causing problems. A major safety hazard. Therefore, in this embodiment, after the main body is connected to the operating handle through the first butt joint end to form a primary tightening, it is also connected to the operating handle through the second external thread of the second butt joint end to form a secondary tightening. In this way, When the embroidery needle head is connected to the operating handle, double fastening is achieved. Even if one fastening becomes loose, the other fastening can prevent the problem of loosening, effectively prevent the occurrence of loosening, and improve the stability and stability of the tattoo. safety.

As shown in Figures 1 to 3, a first connecting thread 7 is provided on the top of the first docking end.

In this embodiment, the body is once tightened through the first docking end and the operating handle through threaded connection.

Wherein, the spiral directions of the first connecting thread and the second external thread are opposite.

In this embodiment, since the first connecting thread and the second external thread have opposite spiral directions, the main body For example, if the operating handle is tightened once and tightened clockwise, then the main body and the operating handle need to be tightened counterclockwise. The two locking rotation directions are opposite. Therefore, no matter which set of tightening is loosened, it will cause The other set of fasteners has a stronger locking force and a better locking effect. Moreover, due to the double fastening in opposite directions, it can further increase the connection strength and tightness between the main body and the operating handle, and prevent the occurrence of problems between the main body and the operating handle. loosen to improve stability and safety during the tattooing process. It also prevents the color material in the body from entering the operating handle after loosening and causing contamination to the operating handle.

Wherein, the pitch of the first connecting thread is greater than the pitch of the second external thread.

The first connecting thread is a coarse thread 8 , and the second external thread is a fine thread 9 .

Coarse threads have a larger lead angle. Since coarse threads have a larger lead angle and pitch, the number of threads is smaller at the same lead distance. Therefore, for coarse threads, the installation accuracy is lower and it is easier to install. Installation and disassembly. However, the anti-vibration performance is relatively weak, the self-locking and sealing properties are relatively poor, and it is easier to loosen. Due to the small thread pitch and small pitch, the fine thread has a large lead distance and a large number of threads, so it has good sealing, weak vibration resistance and good self-locking, and is not prone to loosening, but requires higher installation accuracy. high.

Therefore, in this embodiment, in order to improve the convenience of the initial connection and installation of the operating handle and the body, the operating handle is also provided with a coarse thread corresponding to the coarse thread and a fine thread threaded to the fine thread. The one-time fastening uses coarse threads for screw connection, so that the alignment and screw locking speed block can quickly achieve one-time fastening. As for the fine thread used in the second external thread, since the primary tightening provides a guide and alignment for the secondary tightening, when the fine thread is used for secondary thread tightening, the connection can be made directly and quickly ( In the conventional fine thread connection method, it may be difficult to align the threads multiple times, which may even lead to thread slippage).

See Figure 4. At the same time, the choice between coarse thread and fine thread. In the actual use of embroidery, after a long time and high frequency vibration, the coarse thread will loosen first, that is, the embroidery head will loosen first. The operating handle moves downward, and a loosening movement occurs. However, since the thread pitch angle of the coarse thread is larger than that of the fine thread, under the interference of the same external force, the loosening amplitude of the coarse thread is greater than that of the fine thread. Driven by the aforementioned loosening movement, the thread spacing of the fine threads of the operating handle and the body will gradually disappear along with the loosening direction, and the connection will be squeezed, and the pressure generated will gradually increase, thus causing the operating handle and the body to The contact area and frictional resistance between the two sets of fine threads increase, which will increase the tightening strength of the secondary tightening, that is, improve the tightening performance between the operating handle and the embroidery head. Therefore, coarse threads and fine threads restrict each other, and thread counter-threads restrict each other. It can effectively prevent the tattoo needle from loosening, improve the stability, firmness and safety during the tattoo process, and prevent the tattoo needle from falling off and causing safety hazards.

At the same time, in this embodiment, the first butt end is used as a one-time tightening. Suppose that after one tightening, the middle line of the body and the operating handle does not coincide, indicating that the external tilt or deviation has occurred, and the subsequent fine threads will be difficult to install. , the operator will be able to know that the coarse thread has not been properly screwed, and can just disassemble and re-tighten it. This can avoid the problem of uneven stress on subsequent needle punching components and ensure the embroidery effect.

Referring to Figures 1 to 3, the first connecting thread is a first external thread, the first external thread is provided on the top outer surface of the first docking end, and the second external thread is provided on the third An external thread underneath the outside. In this embodiment, the outer diameter of the second external thread will be larger than the outer diameter of the first external thread, so that the primary tightening and the secondary tightening will not interfere with or affect each other.

In this embodiment, the external threads are used on the first docking end for connection, so corresponding internal threads are provided on the operating handle to match them.
