Description

Technical Field

[0001] This utility model relates to the field of tattoo equipment technology, specifically an electric tattoo pen with adjustable needle stroke. Background Technology

[0002] A tattoo pen uses an internal motor to drive a telescopic rod, which in turn moves the tattoo needle in a reciprocating motion to pierce the skin and achieve a tattoo effect. Modern electric tattoo pens typically have built-in rechargeable batteries, solving the inconvenience of traditional wired tattoo pens, providing greater flexibility, suitable for tattooing at all angles of the body, and can be used in environments without a power source.

[0003] However, current electric tattoo pens have certain limitations. First, the stroke (i.e., the amplitude of the needle's reciprocating motion) of existing tattoo pens is usually fixed, which makes it impossible to adjust the insertion depth according to the thickness of the skin or the fineness of the design when used on different parts of the body. Therefore, the tattoo effect may be limited, especially in areas with fine textures or thin or thick skin.

[0004] While some tattoo devices with adjustable depth are available on the market, these devices typically employ complex mechanical structures, making adjustments inconvenient and potentially affecting device stability. Therefore, an innovative design is urgently needed that allows for flexible needle depth adjustment while maintaining device stability. Utility Model Content

[0005] In view of the above situation and to overcome the current technical defects, this utility model provides an electric tattoo pen with adjustable needle extension stroke and good protective effect. This electric tattoo pen has a simple structure, which can flexibly adjust the needle depth and maintain stable needle extension, thus solving the problem that the needle extension stroke of traditional tattoo pens is not flexible and cannot be adjusted.

[0006] The technical solution adopted by this utility model is as follows: The electric tattoo pen with adjustable needle stroke provided by this solution includes a tattoo pen body, a needle fixing part at the front end of the tattoo pen body, a stroke adjustment module in the middle of the tattoo pen body, and a power output module at the rear end of the tattoo pen body. A spring tattoo needle for tattooing is installed at the front end of the needle fixing part. The stroke adjustment module is used to adjust the length of the needle stroke of the spring tattoo needle. The power output module is used to adjust and control the stroke adjustment module.

[0007] The stroke adjustment module includes a main body with a cylindrical rotating structure. The middle section of the main body has a transverse groove. The front end of the main body has two sets of internally threaded through holes that penetrate the transverse groove. The other end face of the transverse groove has two sets of blind holes corresponding to the threaded holes. One side wall of the main body has multiple sets of holes arranged in a circular pattern. The main body has an elongated hole at the rear end of the hole. Sliding shafts are inserted into the internally threaded through holes. The rear end of the sliding shafts penetrates the internally threaded through holes and is positioned by the blind holes. The front end of the internally threaded through holes is threaded with a screw for locking and fixing the sliding shafts. A slider component slides on the sliding shaft and slides axially along the sliding shaft.

[0008] Furthermore, an eccentric motor is fixedly mounted on one end of the power output module. A bushing part is provided on the motor shaft of the eccentric motor. An inclined bearing is mounted on the bushing part. A disc part is sleeved on the bearing. The disc part has several radially arranged grooves. A component shaft is fixed to one end of the slider part. A ball head is provided at one end of the component shaft. The grooves are adapted to the ball head. The ball head guides, limits, and adjusts the component shaft.

[0009] Furthermore, an elastic steel ball component is provided on the outer casing at the connection between the power output module and the stroke adjustment module, and the elastic steel ball component is engaged with the hole.

[0010] Furthermore, the housing of the power output module is provided with a limiting screw, which slides within an elongated hole provided on the stroke adjustment module. The elongated hole is used to guide the rotation angle of the power output module, thereby achieving the limiting function.

[0011] The beneficial effects of this utility model by adopting the above structure are as follows:

[0012] This electric tattoo pen achieves precise control of the needle's extension stroke through a precise stroke adjustment module and sliding shaft. The automated coordination of the power output module, eccentric motor, and slider components makes stroke adjustment more convenient, simplifying operation and improving work efficiency. The design of the limit screw and elongated hole ensures module stability and avoids the risk of over-adjustment. Furthermore, the engaging design of the elastic steel ball enhances the feel, making the adjustment process more comfortable and easier to control. The overall structure is reasonable, and the combination of locking screws, bushings, and bearings ensures high stability and reliability, extends service life, and can meet different tattooing needs while improving operational flexibility.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0022] This solution provides an adjustable needle extension electric tattoo pen, comprising a tattoo pen body, a needle fixing part 1 at the front end of the tattoo pen body, a stroke adjustment module 2 in the middle of the tattoo pen body, and a power output module 3 at the rear end of the tattoo pen body. A spring tattoo needle 101 for tattooing is installed at the front end of the needle fixing part 1. The stroke adjustment module 2 is used to adjust the extension length of the spring tattoo needle 101. The power output module 3 is used to adjust and control the stroke adjustment module 2. The stroke adjustment module 2 includes a main body part 201 with a cylindrical rotating structure. A transverse groove 202 is provided in the middle section of the main body part 201. Two sets of internally threaded through holes 203 are symmetrically provided at the front end of the main body part 201. A through hole 203 penetrates a transverse groove 202. The other end face of the transverse groove 202 is provided with two sets of blind holes 204 corresponding to the threaded holes. A plurality of sets of holes 205 arranged in a circular pattern are provided around one side wall of the main body part 201. An elongated hole 206 is provided on the main body part 201 at the rear end of the hole 205. A sliding shaft 207 is inserted into the internal threaded through hole 203. The rear end of the sliding shaft 207 passes through the internal threaded through hole 203 and is positioned by the blind hole 204. A screw 208 is threaded to the front end of the internal threaded through hole 203. The screw 208 is used to lock and fix the sliding shaft 207. A slider part 209 is slidably provided on the sliding shaft 207. The slider part 209 slides axially along the sliding shaft 207.

[0023] In this configuration, an eccentric motor 301 is fixedly mounted on one end of the power output module 3. A bushing part 302 is fitted on the motor shaft of the eccentric motor 301. An inclined bearing 303 is mounted on the bushing part 302. A disc part 304 is fitted over the bearing 303. The disc part 304 has several radially arranged grooves 305. A component shaft 210 is fixed to one end of the slider part 209. A ball head 211 is located at one end of the component shaft 210. The grooves 305 and the ball head 211 are connected. The ball head 211 guides, limits, and adjusts the shaft 210 of the component. The power output module 3 and the stroke adjustment module 2 are connected by an elastic steel ball component 306 on the outer shell. The elastic steel ball component 306 is engaged with the hole 205. The housing of the power output module 3 is provided with a limiting screw 307. The limiting screw 307 slides in the elongated hole 206 provided on the stroke adjustment module 2. The elongated hole 206 is used to guide the rotation angle of the power output module 3, thereby achieving the limiting function.

[0024] In practical use, such as Figure 1As shown in Figure 5, when the power output module 3 and the stroke adjustment module 2 are installed, the position of the slot 305 is in contact with the ball head 211 on the part shaft 210 of the stroke adjustment module 2. When the eccentric motor 301 rotates, the part shaft 210 is pressed tightly against the slot 305 on the flower plate part 304 by the elastic pressure of the spring on the needle head. Under the restriction of the slot 305 and the tilt of the flower plate part 304, the rotation of the flower plate part 304 becomes a swing angle a. The swing angle a is converted into the axial back and forth movement of the part shaft 210. When the power output module 3 is rotated, the axial distance d1 between the eccentric motor 301 and the part shaft 210 changes. When the axial distance d1 increases, the outer stroke away from the vertex of the swing angle a will increase. When the axial distance d1 decreases, the inner stroke away from the vertex of the swing angle a will decrease, thereby realizing the function of adjusting the stroke of the needle. When the power output module 3 is rotated, the elastic steel ball part 306 will pop out in the hole 205 set radially around the circumference of the stroke adjustment module 2, thereby generating a rotational damping feel.
