Description

Technical Field

[0001] The utility model relates to the field of tattoos, and particularly to a novel tattoo machine. Background Art

[0002] A tattoo machine is equipped with a reciprocating needle for piercing the skin, and a professional tattoo pigment is attached to the tip of the needle; during the tattooing process, the needle injects the pigment into the inner layer of the skin, thereby forming a permanent and artistic tattoo pattern on the skin.

[0003] Figure 1 、 Figure 2 It is a motor-driven tattoo machine, Figure 1 is the state before the installation of the needle 04 of the motor-driven tattoo machine; Figure 2 is the state after the installation of the needle 04 of the motor-driven tattoo machine; the installation process is as follows: the needle nozzle 03 is fixed to one end of the tubular handle 02, the needle 04 passes through the other end of the tubular handle 02 and reaches inside the needle nozzle 03; the locking bolt 012 fixes the tubular handle 02 and the drive module 01 together; the annular structure at the tail of the needle 04 is sleeved on the outer periphery of the linear reciprocating member 011; the needle 04 follows the linear reciprocating member 011 to pierce the skin.

[0004] The above technology has the following defects: Refer to Figure 2 , during the use process, the tip of the needle 04 will show a reciprocating swing phenomenon of M-N, and the pigment on the tip of the needle 04 will be shaken off.

[0005] The generation of the above defects stems from the fact that the tip of the needle 04 is designed in the form of a row of needles composed of multiple needles arranged. Given that the width of the row of needles is significantly several times larger than the diameter of the main body of the needle 04, the through-hole of the tubular handle 02 must be correspondingly enlarged to ensure the smooth passage of the row of needles. However, this design causes the main body of the needle 04 to swing inside the through-hole of the tubular handle 02 during the process of being driven by the linear reciprocating member 011. Furthermore, the tip of the needle 04 shows a reciprocating swing phenomenon of M-N. Summary of the Utility Model

[0072] It is worth noting that the pressing module 30 presses the main body of the needle tool 04 towards the handle housing 10 side, so that it can move linearly in one direction stably during the reciprocating linear motion; the phenomenon that the tip of the needle tool 04 swings will not occur. Preferably, the pressing module 30 is provided with a roller 64 that can roll, and the roller 64 of the pressing module 30 applies pressure to the main body of the needle tool 04 to make the reciprocating motion of the needle tool 04 smoother.

[0073] In summary, since the pressing module 30 presses the main body of the needle tool 04 towards the handle housing 10 side, so that it can move linearly in one direction stably during the reciprocating linear motion, the phenomenon that the needle array of the needle tool 04 swings will not occur; the purpose that the needle tool 04 will not swing during the working process is achieved.

[0074] Furthermore, a needle tool installation channel 12 is provided on the handle housing 10, the needle tool 04 penetrates through the needle tool installation channel 12, and the pressing module 30 applies pressure to the main body of the needle tool 04, so that the main body of the needle tool 04 is pressed against and adheres to the inner side wall of the installation channel 12 and the needle array of the needle tool 04 adheres to the inner wall of the mouth of the needle nozzle 03; that is, the roller 64 of the pressing module 30 and the inner side wall of the installation channel 12 jointly limit the movement of the needle tool 04 to a one-way linear motion.

[0075] Furthermore, both ends and the outside of the needle installation channel 12 are in an open state, so that the tip row of needles of the needle 04 can be located within the installation channel 12 without passing through the installation channel 12.

[0076] Furthermore, the linear reciprocating module 20 is slidably connected to the handle housing 10; the linear reciprocating module 20 is provided with a pushing groove 20b.

The flexibility spring 28 enables the first sliding seat 21 and the second sliding seat 23 to have a certain buffering and energy absorption effect; that is, after the first sliding seat 21 and the second sliding seat 23 move relative to each other, the flexibility spring 28 will change to absorb energy.

[0083] The convex sleeve core 20a moves along with the first sliding seat 21;

[0084] During the process that the driving part 51 with eccentric motion drives the linear reciprocating module 20 by squeezing the first driving surface 21a and the second driving surface 23b, when the reverse acting force of the skin on the needle 04 is greater than the set threshold value, the flexible spring 28 deforms, and then the first sliding seat 21 and the second sliding seat 23 slide relative to each other; therefore, when the needle 04 is inserted into harder skin tissue, the resistance received by the needle 04 is greater, and then the needle 04 transfers the received resistance to the first sliding seat 21, the flexible spring 28 deforms, and the first sliding seat 21 and the second sliding seat 23 slide relative to each other; the stroke of the convex sleeve core 20a and the needle 04 is shortened, and then the depth of the needle 04 entering the skin is reduced. If the hard part is stabbed too deep, the pigment will bleed.
