A shrapnel tattoo machine, side-rotating shrapnel transmission.

My previous design draft wanted to make a design transformation to adapt to the wireless era.
Therefore, a pre-adaptive transformation plan was made first.

It was originally set at the back of the RCA interface, changed to the side. Also modified the adaptation of the motor (changed to a 2015 outer rotor brushless motor) to modify the original design of the press wheel, changed to the movable press wheel. Elastic pin pressing is achieved by binding it with a rubber band. A handle lock has been changed to fit the new shape.

The original intention of transforming it: Recently, many friends said that they like shrapnel machines.
As it happens, I did do a lot of shrapnel machine drafts before. You can take one directly from the old draft and reform it.

The addition of the battery compartment cannot be directly added to the old draft. It needs to be coordinated and unified, and an adaptive transformation should be made first. Then add another power battery module to it within the scope of capability.
