[0011] The driving assembly is used to drive the rotating shaft to rotate, so as to drive the outer ring outside the rotating shaft to swing up and down, and then drive the extension piece, the lower top piece connected with the extension piece, and the tattoo assembly arranged below the lower top piece to move up and down.

[0012] The adjusting assembly is used to drive the extension piece to move in and out, so as to adjust the fulcrum position of the extension piece and the outer ring, and then adjust the depth of the tattoo assembly moving up and down.

[0013] As a further improvement of the present application, the outer side of the outer ring is provided with a protrusion.

[0014] The convex block is provided with a groove below, and the output end of the telescopic piece is slidingly connected inside the groove of the convex block.

[0015] As a further improvement of the present application, the telescopic piece comprises a lower sleeve and an upper top piece.

[0019] The connecting piece is fixedly connected with the upper top piece at one end and is slidingly connected with the lower top piece at the other end, or is slidingly connected with the upper top piece at one end and is fixedly connected with the lower top piece at the other end.

[0020] As a further improvement of the present application, the transmission assembly further comprises a limiting piece.

[0021] The limiting piece is arranged on the lower sleeve and moves inside the adjusting assembly along with the lower sleeve.

[0022] The limiting piece is provided with a strip-shaped groove inside, and the tattoo assembly is located inside the strip-shaped groove.

[0023] As a further improvement of the present application, the adjusting assembly comprises an adjusting cylinder and a limiting groove.

[0024] The adjusting cylinder is rotatably arranged below the transmission assembly.

[0025] The limiting groove is arranged inside the adjusting cylinder and is used for movably arranging the telescopic piece.

[0026] As a further improvement of the present application, the limiting groove is designed as one end close to the center of the adjusting cylinder and the other end away from the center of the adjusting cylinder, and more preferably, is designed as an arc shape.

[0028] As a further improvement of the present application, the needle cylinder assembly further comprises a needle cylinder.

[0029] The needle mounting cylinder is arranged below the adjusting assembly, such as the adjusting cylinder, and a guide cylinder is arranged in the needle mounting cylinder. The tattooing assembly is arranged inside the guide cylinder, and is used to be pushed out from below the needle mounting cylinder when the tattooing assembly reciprocates up and down.

[0030] As a further improvement of the present application, grooves are arranged on the outer surface of the adjusting cylinder and the needle mounting cylinder.

[0031] Overall, compared with the prior art, the above technical scheme of the present application has the following beneficial effects:

[0032] In the use process of the tattooing pen, the driving assembly is powered on to drive the rotating shaft to rotate, so that the outer ring arranged outside the rotating shaft, which is selectively but not limited to an eccentric rotating ring, swings up and down, thereby driving the telescopic member to extend and retract up and down. The lower pushing member connected to the telescopic end of the telescopic member and the tattooing assembly below the lower pushing member can be driven to move up and down, thereby ensuring that the tattooing assembly reciprocates up and down to complete the tattooing work. The key idea of the present application is that when the amplitude of the reciprocating movement of the tattooing assembly up and down, i.e. the depth of the specific tattooing, needs to be adjusted, the telescopic member can be moved inward or outward by the adjusting assembly to change the fulcrum position of the telescopic member on the outer ring. When the outer ring swings up and down, the telescopic member changes its telescopic amplitude due to the change of the fulcrum position. For example, the up and down amplitude of the outer ring fulcrum is greater than that of the inner ring fulcrum. When the telescopic member is moved outward by the adjusting assembly, the fulcrum of the telescopic member and the outer ring moves outward, and the outer ring swings up and down with the same amplitude, so that the telescopic member located in the outer ring has an increased up and down telescopic amplitude, thereby deepening the up and down movement of the lower pushing member and the tattooing assembly below it. Conversely, when the telescopic member is moved inward by the adjusting assembly, the fulcrum of the telescopic member and the outer ring moves inward, and the outer ring swings up and down with the same amplitude, so that the telescopic member located in the inner ring has a reduced up and down telescopic amplitude, thereby shallowing the up and down movement of the lower pushing member and the tattooing assembly below it. Therefore, when the tattooist needs to adjust the depth of the tattooing pen, he only needs to adjust the fulcrum of the telescopic member and the outer ring by the adjusting assembly. After adjustment, the tattooing pen can carry out tattooing work at the predetermined depth. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0041] In the embodiments, the driving assembly 1 is connected with the transmission assembly 2. Figures 1-3 A tattooing pen with adjustable depth is given, which can optionally but not limitedly include a driving assembly 1, a transmission assembly 2, a tattooing assembly 3 and an adjusting assembly 4.

[0042] The driving assembly 1 is connected with the transmission assembly 2.

[0043] The transmission assembly 2 includes a rotating shaft 21, an outer ring 22 arranged outside the rotating shaft 21, a telescopic piece 23 arranged on the outer ring 22 and a lower top piece 24 connected with the telescopic piece 23.

[0044] The tattooing assembly 3 is arranged below the lower top piece 24.

[0045] The adjusting assembly 4 is connected with the telescopic piece 23.

[0046] The driving assembly 1 is used to drive the rotating shaft 21 to rotate, so as to drive the outer ring 22 outside the rotating shaft 21 to swing up and down, and then drive the telescopic piece 23, the lower top piece 24 connected with the telescopic piece 23 and the tattooing assembly 3 arranged below the lower top piece 24 to move up and down.

[0047] The adjusting assembly 4 is used to drive the telescopic piece 23 to move in and out, so as to adjust the fulcrum position of the telescopic piece 23 and the outer ring 22, and then adjust the depth of the tattooing assembly 3 moving up and down.

[0048] In this embodiment, a tattoo pen with adjustable depth is given. In use, the driving assembly 1 is powered on to drive the rotating shaft 21 to rotate, so that the outer ring 22 arranged outside the rotating shaft 21, which is selectively but not limited to an eccentric rotating ring, swings up and down, thereby driving the telescopic part 23 to extend and retract up and down, and driving the lower top part 24 connected with the telescopic end of the telescopic part 23 and the tattoo assembly 3 below the lower top part 24 to move up and down, so as to ensure the tattoo assembly 3 to reciprocate up and down and complete the tattoo work. The key concept of the present application lies in that when the amplitude of the reciprocating movement of the tattoo assembly 3 up and down, i.e. the depth of the specific tattoo, needs to be adjusted, the telescopic part 23 can be moved inward or outward by the adjusting assembly 4 to change the fulcrum position of the telescopic part 23 on the outer ring 22, so that when the outer ring 22 swings up and down, the telescopic part 23 changes the telescopic amplitude due to the change of the fulcrum position. For example, the up and down amplitude of the outer ring fulcrum is greater than that of the inner ring fulcrum. When the telescopic part 23 moves outward under the driving of the adjusting assembly 4, the fulcrum of the telescopic part 23 and the outer ring 22 moves outward, and the outer ring 22 swings up and down with the same amplitude, so that the up and down telescopic amplitude of the telescopic part 23 located in the outer ring is enhanced, thereby deepening the depth of the up and down movement of the lower top part 24 and the tattoo assembly 3 below it. Conversely, when the telescopic part 23 moves inward under the driving of the adjusting assembly 4, the fulcrum of the telescopic part 23 and the outer ring 22 moves inward, and the outer ring 22 swings up and down with the same amplitude, so that the up and down telescopic amplitude of the telescopic part 23 located in the inner ring is weakened, thereby shallowing the depth of the up and down movement of the lower top part 24 and the tattoo assembly 3 below it. Therefore, when the tattoo artist needs to adjust the depth of the tattoo pen, he only needs to adjust the fulcrum of the telescopic part 23 and the outer ring 22 through the adjusting assembly 4, and after adjustment, the tattoo pen can carry out tattoo work at the predetermined depth. It can be seen that the tattoo pen with adjustable depth can conveniently adjust the depth of the tattoo pen, which is simple and flexible to operate. It is worth noting that the tattoo pen can be applied to beauty, scalp, tattoo, tattoo and other work.

[0049] More notably, the technical core of the present application lies in that the transmission assembly composed of the rotating shaft 21, the outer ring 22, the telescopic part 23 and the lower top part 24 is arranged, and the fulcrum position of the telescopic part 23 and the outer ring 22 in the transmission assembly is adjusted through the adjusting assembly 4, thereby adjusting the depth of the up and down movement of the lower top part 24 driven by the telescopic part 23, i.e. adjusting the up and down movement depth of the tattoo assembly 3 below the lower top part 24, realizing the adjustment of the depth of the tattoo pen, and the preferred embodiment is given below, but it is not limited thereto.

[0056] More preferably, as shown, the telescopic piece 23 can optionally but not limitedly include a lower sleeve 231 and an upper top piece 232; Figure 4

[0057] The lower sleeve 231 is located inside the adjustment assembly 4 and is driven by the adjustment assembly 4 to move;

[0058] The upper top piece 232 is telescopically arranged inside the lower sleeve 231 at the lower end, and the upper end is slidingly arranged inside the groove of the protrusion 221.

[0059] In this embodiment, a preferred embodiment of the telescopic piece 23 is given, which is used to drive the lower sleeve 231 inside to move through the adjustment assembly 4, and then drive the upper top piece 232 to slide inside the groove of the protrusion 221, so that the upper top piece 232 is located at different positions inside the protrusion 221 when the outer ring 22 swings up and down, the contact position between the two, i.e. the fulcrum position, is changed, the telescopic distance of the upper top piece 232 inside the lower sleeve 231 changes when the outer ring 22 swings up and down, specifically; when the fulcrum moves from the outer ring to the inner ring, the telescopic distance becomes shorter; when the fulcrum moves from the inner ring to the outer ring, the telescopic distance becomes longer, so that the depth of the up and down movement of the tattooing assembly 3 changes.

[0060] More preferably, as shown, the transmission assembly 2 can also optionally but not limitedly include a connecting piece 25; Figure 4

[0061] ​​​The connecting piece 25 is fixedly connected with the upper top piece 232 at one end and is slidably connected with the lower top piece 24 at the other end, or is slidably connected with the upper top piece 232 at one end and is fixedly connected with the lower top piece 24 at the other end. Specifically, as shown in Figure 4 Fig. 13, a preferred embodiment of the connecting piece 25 is given, which is selected but not limited to a connecting rod, a through hole is arranged at one end of the connecting rod, the connecting rod is sleeved on the upper top piece 232, and the other end of the connecting rod is arranged to penetrate into the lower top piece 24 to be slidably connected with the lower top piece 24.

[0062] In this embodiment, the transmission assembly 2 of the present application is additionally provided with the connecting piece 25 to adjust the movement of the lower sleeve 231 driven by the assembly 4, so that the connecting piece 25 is always connected with the lower top piece 24 when the lower top piece 24 is moved to approach the lower top piece 24, the distance between the upper top piece 232 and the lower top piece 24 is quickly and conveniently changed when the position of the fulcrum is adjusted, and the depth of the up-and-down movement of the lower top piece 24 driven by the upper top piece 232 is adjusted.

[0063] More preferably, as shown in Figure 4 Fig. 14, the transmission assembly 2 can also be selected but not limited to comprising a limiting piece 26.

[0064] The limiting piece 26 is arranged on the lower sleeve 231 and moves with the lower sleeve 231 inside the adjusting assembly 4.

[0065] The limiting piece 26 is internally provided with a strip-shaped groove 261, and the tattoo assembly 3 is located inside the strip-shaped groove 261.

[0066] In this embodiment, a plurality of specific preferred embodiments of the transmission assembly 2 are given, when the lower sleeve 231 is moved together with the adjusting assembly 4, the upper top piece 232 inside the lower sleeve 231 and the connecting piece 25 connected with the upper top piece 232 are moved, so that the fulcrum position of the upper top piece 232 in the groove inside the protrusion 221 is changed, when the outer ring 22 and the protrusion 221 are swung up and down, the amplitude of the sliding of the upper top piece 232 inside the lower sleeve 231 is changed according to the different fulcrum positions of the upper top piece 232 on the protrusion 221, so that the lower top piece 24 connected with the upper top piece 232 through the connecting piece 25 and the tattoo assembly 3 below the lower top piece 24 change the depth of the up-and-down movement.

[0067] Three, the tattoo assembly 3

[0068] Preferably, as shown in Figure 3 Fig. 15, the tattoo assembly 3 can be selected but not limited to a tattoo needle, a tattoo knife and other tattoo tools, and preferably is sequentially driven by the driving assembly 1 and the transmission assembly 2, such as the rotating shaft 21, the outer ring 22, the upper top piece 232, the connecting piece 25 and the lower top piece 24, to move up and down to complete the tattoo work.

[0069] Four, the adjusting assembly 4

[0070] Preferred, such as Figure 5 As shown, the adjustment component 4 may optionally include, but is not limited to, the adjustment cylinder 41 and the limiting groove 42;

[0071] The adjusting cylinder 41 is rotatably located below the transmission assembly 2; preferably, it is located below the telescopic member 23.

[0072] The limiting groove 42 is located inside the adjusting cylinder 41 and is used to movably install the telescopic member 23; preferably, the lower sleeve 231 of the telescopic member 23 is located inside the limiting groove 42.

[0073] More specifically, the shape of the limiting groove 42 can be, but is not limited to, having one end close to the center of the adjusting cylinder 41 and the other end away from the center of the adjusting cylinder 41; more preferably, it is an arc-shaped design.

[0074] After the adjusting cylinder 41 is rotated, the lower end of the telescopic component 23 will be driven, preferably the lower sleeve 231, to move within the limiting groove 42, so as to... Figure 5 Taking the shape of the limiting groove 42 as an example, when the adjusting cylinder 41 rotates clockwise, the telescopic member 23 moves outward, away from the center. The telescopic member 23 moves outward on the outer ring 22, causing the fulcrum between them to move outward. The outer ring 22 swings up and down with the same amplitude, which increases the amplitude of the telescopic member 23's vertical extension and retraction on the outer ring, thereby increasing the depth of the vertical movement of the lower top member 24 and the tattoo component 3 below it. Conversely, when the adjusting cylinder 41 rotates counterclockwise, the telescopic member 23 moves inward, closer to the center. The telescopic member 23 moves inward on the outer ring 22, causing the fulcrum between them to move inward. The outer ring 22 swings up and down with the same amplitude, which weakens the amplitude of the telescopic member 23's vertical extension and retraction on the inner ring, thereby decreasing the depth of the vertical movement of the lower top member 24 and the tattoo component below it. Therefore, when a tattoo artist needs to adjust the depth of the tattoo pen, they only need to rotate the adjusting cylinder 41 to adjust the fulcrum of the telescopic component 23 and the outer ring 22. After adjustment, the tattoo pen can carry out tattooing work at the predetermined depth.

[0075] More preferably, such as Figures 4-5 As shown, the telescopic component 23 and the adjusting cylinder 41 are interlocked. Rotating the adjusting cylinder 410-80° causes the lower sleeve 231 to move longitudinally, which in turn moves the upper top component 232, changing the lever fulcrum position of the upper top component 232 and the protrusion 221, thereby changing the depth of the vertical movement of the tattoo component 3. For example, it can be adjusted from 2.3MM to 4.2MM, allowing for variable depth adjustment.

[0076] In this embodiment, a plurality of specific preferred embodiments of the adjusting assembly 4 are given, and the adjusting cylinder 41 will drive the lower end of the telescopic member 23 after rotation, such as the sleeve 231, to move in the track of the limiting groove 42. According to the shape design of the limiting groove 42, the upper end of the telescopic member 23, such as the jacking piece 232, will move horizontally inside the protrusion 221, so as to change the fulcrum position of the jacking piece 232 inside the protrusion 221.

[0077] V. Needle cylinder assembly 5

[0078] Preferably, as shown in the drawings, the tattoo pen with adjustable depth of the present application can optionally but not limited to include a needle cylinder assembly 5, which includes: Figure 6

[0079] The needle cylinder 51 is arranged below the adjusting assembly 4, and the guide cylinder 52 is arranged inside the needle cylinder 51. The tattoo assembly 3 is located inside the guide cylinder 52, which is used to push out the tattoo assembly 3 from below the needle cylinder 51 when the tattoo assembly 3 moves up and down reciprocally, and the guide cylinder 52 limits the movement of the tattoo assembly 3 to prevent it from shaking during movement.

[0080] More preferably, as shown in the drawings, the sliding groove 53 can be optionally but not limited to be arranged inside the needle cylinder 51, and cooperates with the lower end of the adjusting cylinder 41, which is used to cooperate with the adjusting cylinder 41 to rotate. Figure 6

[0081] In this embodiment, a specific preferred embodiment of the needle cylinder assembly 5 is given. When the tattoo assembly 3 moves up and down reciprocally, the guide cylinder 52 limits the movement of the tattoo assembly 3 to prevent it from shaking during movement, and makes the tattoo assembly 3 move out from below the needle cylinder 51. The user can perform tattoo work by holding the needle cylinder 51.

[0082] Preferably, as shown in the drawings, the outer surface of the adjusting cylinder 41 and the needle cylinder 51 can optionally but not limited to be provided with a groove, which is used to increase the friction force of the contact surface between the hand and the adjusting cylinder 41 and the needle cylinder 51 when the adjusting cylinder 41 is rotated and the needle cylinder 51 is held, so as to make it more convenient to rotate the adjusting cylinder 41 and hold the needle cylinder 51. Figure 2

[0083] ​​​The tattoo pen with adjustable depth of the present application, when the driving assembly 1 is powered on, the rotating shaft 21 is driven to rotate, the outer ring 22 swings up and down, the upper top piece 232 inside the protruding block 221 is driven to stretch and contract inside the lower sleeve 231, the connecting piece 25 and the lower top piece 24 connected with the upper top piece 232 are driven to move up and down, and the tattoo assembly 3 below the lower top piece 24 is driven to reciprocate up and down inside the guide cylinder 52, thereby completing the tattoo work. When it is necessary to adjust the depth of the tattoo assembly 3 jutting out from below the needle mounting cylinder 51, the lower sleeve 231 can be moved transversely according to the track of the limiting groove 42 by rotating the adjusting cylinder 41, so that the upper top piece 232 moves transversely inside the protruding block 221, thereby changing the fulcrum position, so that when the protruding block 221 swings up and down, the amplitude of the up and down movement of the protruding block 221 driven by the upper top piece 232 is different according to the different fulcrum positions of the upper top piece 232 inside the protruding block 221, thereby adjusting the amplitude of the up and down movement of the tattoo assembly 3 below the lower top piece 24.

[0084] It is worth noting that the tattoo pen with adjustable depth of the present application is based on the basic principle of adjusting the fulcrum position of the telescopic piece 23 and the outer ring 22 by driving the telescopic piece 23 to move inside and outside, thereby adjusting the depth of the up and down movement of the tattoo assembly, but the specific implementation is not limited to the above text and drawings. The above specific examples only give one way of adjusting the fulcrum position of the telescopic piece 23 and the outer ring 22 by rotating the adjusting cylinder 41 and the eccentric limiting groove 42 clockwise and counterclockwise to drive the telescopic piece 23 to move inside and outside. For example, to adjust the fulcrum position of the telescopic piece 23 and the outer ring 22, the specific structure of the tattoo pen of the present application can also be selected but is not limited to:

[0085] The adjusting cylinder 41 is provided with a pushing piece, and the pushing piece is connected with the telescopic piece 23, such as the lower sleeve 231. The pushing piece can be a push block or a screw rod. By pushing into the adjusting cylinder 41 or screwing the screw rod into the adjusting cylinder 41, the lower sleeve 231 inside the adjusting cylinder 41 is driven to move inward, thereby changing the fulcrum position of the upper top piece 232 at the upper end of the telescopic piece 23 inside the protruding block 221 of the outer ring 22. By pulling out of the adjusting cylinder 41 or screwing the screw rod out of the adjusting cylinder 41, the lower sleeve 231 inside the adjusting cylinder 41 is driven to move outward, thereby changing the fulcrum position of the upper top piece 232 inside the protruding block 221.
