摘要：
The present invention discloses a non-resilient tattooing needle and a tattooing device using the same. The needle comprises a barrel, a needle body, a needle base, a first connecting rod and a first connecting part. The first connecting part of the present invention reciprocates under an external force and thus drives the needle body, via the first connecting rod and the needle base, to reciprocate linearly in the barrel. The advantageous effects of the present invention are as below: instead of using a spring, a rubber band or a rubber ring to provide a resilient force, the needle of the present invention is driven by an external force directly which enables the needle to retract quickly； such a problem is avoided that resilient forces diminish or even disappear after long-term use of the spring, the rubber band or the rubber ring which causes the needle cannot retract. The present invention also provides a tattooing device comprising an electric motor, a handle housing, a second connecting rod and an aforementioned tattooing needle. When pushing out the needle body, the electric motor does not need to work against resilient forces. Therefore, both the current and power of the electric motor are kept stable which thereby greatly prolongs the service life thereof.
