[0001] The utility model relates to the technical field of tattoo pen design, in particular to a novel tattoo pen handle. Background Art
[0002] Tattoo, also known as tattoo, is a process of piercing the bottom layer of the skin with a colored needle to create some patterns or words on the skin, that is, piercing the skin and applying pigment to the wound to make the body have permanent patterns. Tattoos are completed with a tattoo pen. Existing tattoo pens generally include a pen body and a handle. At present, in order to keep the tattoo pen clean, a plastic bag is usually placed on the outside of the pen body of the tattoo pen, and then the handle is installed at the end of the tattoo pen. Since the handle and the pen body are threaded, the plastic bag between the two will move or wrinkle during the installation of the handle, resulting in inconvenience in use. In addition, when the handle of the existing tattoo pen is turned, the pen needle can be extended outward or inward to facilitate the tattoo operation, but when the pen needle moves to the specified position, there is no locking structure to limit the pen needle, so that the problem of flying needles occurs during use, affecting use.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] like Figure 1-8 As shown, a new tattoo pen handle includes a rotating kit, which includes an inner shell 2. A slot 202 is provided at the end of the inner shell 2. One end of a bag 6 can be installed in the slot 202. After the tattoo pen and the handle are assembled, the bag 6 is unfolded to wrap the tattoo pen.
[0031] Among them, the card slot 202 is an annular through groove arranged at the end of the inner shell 2, and the cross-sectional shape of the card slot 202 is L-shaped, and the bottom edge of the L-shaped structure extends toward the center direction of the inner shell 2; a rubber band is installed at one end of the bag 6, and the rubber band can be installed in the card slot 202, so as to realize the connection between the bag 6 and the inner shell 2. The bag 6 is an open-ended structure, one end of which is equipped with a rubber band. The rubber band can be used to fix one end of the bag 6 in the card slot 202. After the bag 6 is unfolded, the tattoo pen can be wrapped, thereby achieving a dustproof and waterproof effect.
[0032] A core sleeve 5 is installed inside the rotating sleeve, which can rotate relative to the rotating sleeve and move axially when the rotating sleeve rotates. The core sleeve 5 is provided with an internal thread 501. The needle of the tattoo pen can be threadedly installed in the core sleeve 5. When the core sleeve 5 moves axially, the needle moves axially outward or inward.
[0033] Specifically, the rotating kit also includes a rotating pulley 3 fixed inside the inner shell 2. The rotating pulley 3 is installed at the installation position 205 opened inside the inner shell 2. A spiral guide groove 301 is opened in the circumferential direction of the rotating pulley 3. The rotating pulley 3 and the inner shell 2 are in a relatively static state, that is, when the inner shell 2 rotates, the rotating pulley 3 also rotates together.
[0034] Specifically, a limiting sleeve 4 capable of rotating relative to the rotating pulley 3 is installed inside the rotating pulley 3, and the core sleeve 5 is synchronously rotatably connected in the limiting sleeve 4, wherein the limiting sleeve 4 and the rotating pulley 3 are concentrically arranged, and there is a relative rotational freedom between the two.
[0035] More specifically, a limiter is installed in the circumferential direction of the limit sleeve 4, and a plurality of tooth grooves 204 are evenly distributed along the axial direction of the inner shell 2. The outer end of the limiter can move into the tooth groove 204 to achieve the limiting effect of the limit sleeve 4 and the inner shell 2; wherein the limiter is a spring plunger, also known as a ball plunger, and there are two of them. The limit sleeve 4 is provided with two symmetrical first mounting holes 402 in the circumferential direction, and the limiter is installed in the first mounting hole 402. Since the limit sleeve 4 and the rotating pulley 3 rotate relative to each other, the rotating pulley 3 It rotates synchronously with the inner shell body 2. Therefore, when the handle rotates, the limiter on the limit sleeve 4 can engage with the tooth groove 204 disposed on the inner wall of the inner shell body 2, so that a "clicking" sound is emitted during the rotation of the handle, which is convenient for the operator to judge the number of rotations of the handle and then the axial movement distance of the stylus. On the other hand, due to the cooperation between the limiter and the tooth groove 204, the limiting effect of the rotating kit can be achieved, so that after the steel ball at the front end of the limiter is stuck in the tooth groove 204, the pen needle is prevented from shaking, avoiding the problem of flying needles.
[0036] Specifically, the core sleeve 5 is provided with a guide column extending outward in the circumferential direction, which is not shown in the figure and can be a pin or rod-shaped structure; the limiting sleeve 4 is provided with a through strip hole 401 in the circumferential direction, and the length direction of the strip hole 401 is consistent with the axial direction of the limiting sleeve 4, and the guide column is placed in the strip hole 401 to realize the synchronous rotation of the core sleeve 5 and the limiting sleeve 4, and the guide column extends into the guide groove 301 of the rotating pulley 3, and when the rotating pulley 3 rotates, the core sleeve 5 is realized by using the guide groove 301. axial movement; more specifically, a second mounting hole 502 is opened in the circumferential direction of the core sleeve 5, and the guide column is installed at the second mounting hole 502 and extends outward, so that the guide column passes through the strip hole 401 of the limiting sleeve 4 and is placed in the guide groove 301 of the rotating pulley 3. In this way, in the process of turning the handle, after the rotating pulley 3 rotates, the axial force can be applied to the guide column by utilizing the cooperation between the guide groove 301 and the guide column, so that the core sleeve 5 moves axially, that is, the guide column moves along the strip hole 401 of the limiting sleeve 4.
[0037] Specifically, the outer shell 1 is fixed to the outside of the inner shell 2, and the outer shell 1 has concave anti-skid patterns on the outside, which is convenient for operators to hold and has an anti-skid effect.
[0038] Specifically, the inner shell 2 is provided with a plurality of conical steps, such as Figure 4 As shown, it includes a first tapered step 201 near the end position and a second tapered step 203 near the middle position, the purpose of which is to facilitate the assembly of the handle and the tattoo pen.
[0039] When the new tattoo pen handle is in use, the tattoo pen can be installed in conjunction with the handle. After the assembly is completed, the sleeve 6 installed at the end of the inner shell 2 can be changed from a folded state to an unfolded state, thereby wrapping the tattoo pen to achieve a dustproof and waterproof effect. By rotating the handle, the core sleeve 5 inside the handle can be moved axially, so that the pen needle installed on the core sleeve 5 has a telescopic effect, which is convenient for the operator to adjust the extended position of the pen needle, and is convenient and quick. In addition, when adjusting the telescopic position of the pen needle, the limiter can not only cooperate with the tooth groove 204 at the inner wall of the inner shell 2, and the sound emitted can facilitate the operator to judge the number of rotations of the handle, and then judge the length of the pen needle, but also can use the limiting effect of the limiter and the tooth groove 204 to prevent the pen needle from flying, so as to improve the quality of the tattoo.
[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
