Tattooing needle assembly

A support assembly device for rapidly changing tattooing needles comprising:

• a partially enclosed needle holder with an opening at one end;
• a laterally-sliding locking plate sized and shaped to mate with the needle holder, the locking plate being positioned between an upper clamping plate and a lower clamping plate;
• and
• a needle protection sleeve;
• wherein the upper clamping plate is provided with a plurality of holes;
• wherein the locking plate is provided with a plurality of locking holes corresponding with the upper clamping plate holes, the locking plate holes each having a width smaller than a width of the upper clamping plate holes;
• wherein the needle protection sleeve is sized and shaped to couple with the upper clamping plate holes, each needle protection sleeve comprises a sleeve body and a sleeve base, a bottom portion of the sleeve body is connected with the sleeve base, a spacing groove is between the sleeve body and the sleeve base;
• wherein the locking plate is sized and shaped to couple with the spacing groove to tightly lock and fix the needle protection sleeve on the needle holder;
• wherein the lower clamping plate is provided with a plurality of lower plate holes corresponding with the upper clamping plate holes, the lower plate holes sized and shaped to match with the sleeve base.

A method of installing a tattooing needle assembly to a tattooing machine, the method comprising:

• positioning a needle protection sleeve over a needle assembly such that the needle assembly is prevented from rotating relative to the needle protection sleeve;
• positioning the tattooing machine in close proximity to the needle assembly such that a proximal end of the needle assembly can be received by the tattooing machine;
• and
• rotating the needle protection sleeve relative to the tattooing machine, thereby causing the needle assembly to rotate relative to the tattooing machine, until the needle assembly is locked onto the tattooing machine.

A method of removing a tattooing needle assembly from a tattooing machine, the method comprising:

• positioning a needle protection sleeve over a needle assembly such that the needle assembly is prevented from rotating relative to the needle protection sleeve;
• rotating the needle protection sleeve relative to the tattooing machine, thereby causing the needle assembly to rotate relative to the tattooing machine, until the needle assembly is unlocked from the tattooing machine;
• and
• separating the tattooing machine from the needle assembly while the needle protection sleeve is still positioned over the needle assembly.
