0.20mm；Needle tail part is plugged in the space formed by a plurality of positioning convex muscle envelope in the way of tight fit, per adjacent
Two positioning convex muscle, appearance glue chamber, the tattooing needle are respectively formed between the inner surface of mounting hole and the outer surface of needle tail part
Formed a fixed connection by the viscose glue being filled in multiple appearance glue chambers with needle handle.
Preferably：The positioning convex muscle is semi-cylindrical hill muscle.
Preferably：The part that mounting hole is set on needle handle is cylindrical, and mounting hole uses circular port, and needle tail part is in cylinder
Shape, the positioning convex muscle being arranged on mounting hole is three.
Preferably：The part that mounting hole is set on needle handle is in square column type, and the mounting hole is square opening, and needle tail part is in side
Cylindricality, is arranged on positioning convex muscle on mounting hole for six, wherein each on two faces wide of square opening set two,
Each on two leptoprosopy of square opening to set one, the positioning convex muscle on two faces wide is set in mirror image, determining on two leptoprosopy
Position raised ribs are set in mirror image.
Preferably：Taper guide hole is provided with the front end of mounting hole, it is divided in taper guide hole and corresponding Aculeata
Between form ring cavity, in ring cavity be filled with viscose glue.
The utility model has the advantages and positive effects that：
This fixed connection structure, by setting a plurality of positioning being circumferentially evenly arranged in the mounting hole of needle handle leading section
Raised ribs, make the top of a plurality of positioning convex muscle be formed with the needle tail part of tattooing needle and coordinate, so, in the Aculeata of tattooing needle
In the case of point excessive with the fit clearance of the mounting hole of needle handle and too small, can be by the different distortion amount pair of positioning convex muscle
Needle tail part is played a supporting role, so as to ensure that the concentricity of tattooing needle and needle handle；In addition, two adjacent positioning convex
Appearance glue chamber is respectively formed between muscle, the inner surface of mounting hole and the outer surface of needle tail part, is glued by holding filling in glue chamber to multiple
Glue realizes the fixation of tattooing needle and needle handle, and it directly sets compared to existing needle tail part outer surface and needle handle mounting hole and glue
The mode of glue, increased adhesive glue amount, improve the firmness of connection.This fixed connection structure ensure that needle tail part is smooth
It is inserted into the mounting hole of needle handle, so, facilitates assembling and improve packaging efficiency.
