[0030] The utility model aims to provide a tattoo pen with adjustable stroke.

[0031] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0032] See also Figure 1 and Figure 2 The present embodiment provides an adjustable stroke tattoo pen, comprising: a link sleeve 01, a spherical axis 02, an adjusting ring 05 and a push rod assembly; the link sleeve 01 is a cylindrical structure; the spherical axis 02 is a spherical structure as a whole, and a first through hole passing through the spherical center is provided inside the link sleeve 01, the spherical axis 02 is installed inside the link sleeve 01 through a bearing bush assembly, a motor 03 is fixedly installed inside the first through hole, a swing plate 04 is fixed at a certain angle on the movable end of the motor 03, and the rotation of the motor 03 can drive the swing plate 04 to swing; the adjusting ring 05, installed inside the connecting sleeve 01, and sleeved on the top outer circumference of the motor 03 in the first through hole, an eccentric hole 06 is provided inside the adjusting ring 05; the push rod assembly is installed inside the transmission bin 07, and the transmission bin 07 is installed at the end of the connecting sleeve 01 away from the adjusting ring 05, the push rod assembly is contacted and arranged at an eccentric position on the bottom surface of the swing plate 04, and the swing plate 04 is displaced by the rotation between the adjusting ring 05 and the push rod assembly through the spherical axis 02, thereby changing the distance between the top of the push rod assembly and the center of the swing plate 04.

[0033] Specifically, the link sleeve 01 is a sleeve-type structure, in which a spherical axis 02 is movably installed through a bearing assembly, that is, the spherical axis 02 can rotate and move in the bearing assembly, and the bearing assembly is nested in the middle of the link sleeve 01, and a first through hole is provided in the middle of the spherical assembly, in which a motor 03 is installed, and the upper end of the motor 03 passes through the bearing assembly, and an adjusting ring 05 is nested at the upper end inside the link sleeve 01, and the adjusting ring 05 is an annular structure, but the hole inside is an eccentric hole 06, and the eccentric hole 06 of the adjusting ring 05 is just sleeved on the upper end of the motor 03 in the installed state, and the tail of the motor 03 is deflected by rotating the adjusting ring 05, thereby realizing the deflection of the output end of the motor 03, and then the distance of the push rod assembly relative to the center of the swing plate 04 is changed through the swing plate at the movable end of the motor 03, thereby changing the stroke of the tattoo pen.

[0034] That is to say, after the tattoo pen is installed in place, the eccentric hole 06 can be rotated by rotating the adjusting ring 05, and the eccentric hole 06 is connected to the top of the motor 03 in the connecting sleeve 01, and the eccentric hole 06 will drive the top of the motor 03 to swing. The middle part of the motor 03 is installed in the bearing bush assembly through the spherical axis 02, so that the motor 03 can swing with the spherical axis 02 as the rotation point. Therefore, when the top of the motor 03 swings, the bottom of the motor 03 will swing in the opposite direction. The movable end of the motor 03 is connected to the swing plate 04 at a certain angle, and the swing plate 04 will swing when the motor 03 is working. When the motor 03 swings under the action of the adjusting ring 05, the swing plate 04 will swing, thereby changing the distance between the top of the push rod assembly and the center of the swing plate 04. When the motor 03 drives the swing plate 04 to swing again, the position of the top of the push rod assembly abutting against the swing plate 04 changes, and the stroke of the push rod assembly will also change. In this way, the tattoo pen can change its stroke through simple operation, and there is no need to disassemble the machine and replace the swing plate 04 every time the stroke is changed, which greatly improves the convenience of using the tattoo pen.

[0035] Preferably, the cross-sectional shape of the first through hole is circular, and the inner diameter of the first through hole is the same as the outer diameter of the motor 03 .

[0036] It can be understood that in the present embodiment, the motor 03 is a columnar structure. Therefore, in order to fit the motor 03 exactly, the first through hole in the middle of the spherical axis 02 is also configured to have a shape and size that matches the motor 03 .

[0037] Of course, the shape of the first through hole is not fixed, and needs to be adjusted according to the actual situation of the motor 03. No specific limitation is made here, as long as it can achieve the above purpose.

[0038] Preferably, the bearing assembly includes an upper bearing 08 and a lower bearing 09 , and spherical grooves are provided inside the upper bearing 08 and the lower bearing 09 . The upper bearing 08 and the lower bearing 09 are symmetrically connected and can embrace the spherical axis 02 .

[0039] like Figure 2 As shown, in this embodiment, the spherical axis 02 needs to be able to rotate in the bearing assembly, so a spherical groove is set inside the bearing assembly to match the spherical axis 02, that is, the bearing assembly can just embrace the spherical axis 02 through the internal spherical groove. Furthermore, in order to facilitate the installation of the spherical axis 02, the bearing assembly is divided into two parts from the middle position, namely the upper bearing 08 and the lower bearing 09, and in this embodiment, the joint of the upper bearing 08 and the lower bearing 09 is provided with a protrusion and a groove that can be engaged with each other.

[0040] Preferably, a second through hole is provided at the bottom of the spherical groove of the upper bearing shell 08 and the lower bearing shell 09. The second through hole has a conical structure, and the opening of the second through hole increases linearly in a direction away from the spherical groove.

[0041] It can be understood that the motor 03 is penetrated through the middle of the spherical axis 02, and the upper end of the motor 03 needs to pass through the upper bearing 08 and be nested in the eccentric hole 06 of the adjusting ring 05. The upper end of the motor 03 is swung by rotating the adjusting ring 05 to achieve the purpose of swinging the movable end of the motor 03. Therefore, in order to allow the upper and lower movable ends of the motor 03 to swing freely and have a larger swinging range, the bottom of the spherical groove of the upper bearing 08 and the lower bearing 09 are provided with a second through hole with a conical structure, and the opening of the second through hole is gradually opened in the direction away from the spherical groove.

[0042] Preferably, grease is applied between the spherical groove and the spherical axis 02 to reduce the wear of the spherical axis 02 .

[0043] It can be understood that since the spherical axis 02 rotates in the spherical groove and the two are in direct contact, in order to reduce the mutual friction between the two and prevent excessive wear, grease is applied between the spherical groove and the spherical axis 02, which can increase the flexibility of the rotation of the spherical axis 02.

[0044] Preferably, the diameter of the eccentric hole 06 of the adjusting ring 05 is the same as the diameter of the motor 03 , so that the adjusting ring 05 can stably control the deflection of the motor 03 .

[0045] It can be understood that in order to enable the adjustment ring 05 to sensitively and accurately control the deflection of the motor 03, the eccentric hole 06 of the adjustment ring 05 needs to exactly match the upper end diameter of the motor 03. Therefore, the diameter of the eccentric hole 06 of the adjustment ring 05 needs to be selected according to the actual diameter of the motor 03; however, the size of the eccentric hole 06 in the adjustment ring 05 that deviates from the center of the adjustment ring 05 can be adjusted according to actual conditions, and this article does not make specific limitations.

[0046] Preferably, the transmission chamber 07 is a cylindrical structure and is threadedly connected to the connecting sleeve 01.

[0047] like Figure 1 As shown, in this embodiment, the push rod assembly is installed inside the transmission chamber 07. The transmission chamber 07 is also configured as a cylindrical structure for the sake of overall aesthetics and integrity with the connecting sleeve 01. The diameter of the transmission chamber 07 matches the diameter of the connecting sleeve 01, and the two are connected by threads.

[0048] Preferably, the ejector assembly includes an ejector rod 10 telescopically arranged at the bottom of the transmission bin 07 , and a connecting slider 11 movable in the extended axial direction inside the transmission bin 07 , and the connecting slider 11 is fixedly mounted on the top of the ejector rod 10 .

[0049] Specifically, the ejector rod 10 of the ejector rod assembly is telescopically arranged in the middle position of the transmission bin 07, and the up and down movement of the ejector rod 10 is achieved by a connecting slider 11, which is fixedly connected to the upper end of the ejector rod 10, and the connecting slider 11 can move up and down along its axis inside the transmission bin 07.

[0050] Preferably, a transmission rod 12 is connected to the connecting slider 11 , and the top end of the transmission rod 12 abuts against the bottom of the swing plate 04 .

[0051] Furthermore, the connecting slider 11 is connected to the transmission rod 12, and the top end of the transmission rod 12 abuts against the bottom surface of the swing plate 04. When the swing plate 04 is deflected under the action of the adjusting ring 05, since the top end position of the transmission rod 12 remains unchanged, the distance from the position where the top end of the transmission rod 12 abuts against the ground of the swing plate 04 to the center of the swing plate 04 will change. When the motor 03 works again, the stroke of the swing plate 04 for the transmission rod 12 to move up and down will change.

[0052] Preferably, the link sleeve 01, the spherical axis 02 and the bearing assembly are all made of aluminum alloy.

[0053] In this embodiment, the link sleeve 01, the spherical axis 02 and the bearing assembly are preferably made of aluminum alloy, so that the weight of the tattoo pen can be reduced while ensuring the overall strength of the tattoo pen, making it easier for operators to operate.

[0054] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0055] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0056] The above is a detailed introduction to the embodiments provided by the utility model. This article uses specific examples to illustrate the principles and implementation methods of the utility model. The description of the above embodiments is only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
