Description

Handheld pen power degree adjusting assembly of line thorn instrument

Technical Field

The invention relates to the technical field of eyebrow tattooing, in particular to a handheld pen strength adjusting assembly of an eyebrow tattooing tool.

Background

In the prior art, the leading-in depth is controlled by controlling the exposed length of the needle point, but because the skin hardness degree and the skin pulling force are different, and the skin has elasticity, the skin is sunken to avoid the needle point out-of-needle length when the needle point is punctured back and forth, so that an operator needs to control the leading-in depth by experience to carry out the operation. Still some equipment use motor current size to detect the degree of depth of penetrating the skin, but this mode belongs to passive suggestion, only sends the warning when using the dynamics too big to relative cost is slightly high. And the hard connecting rod is partially used for installing a spring, and the pressing spring is used for absorbing pressing force, so that the pressed light spring absorbs the pressing force, and the pressed heavy skin is heavy in resilience force, so that the problem of balanced output cannot be solved, and the safety control and the stop protection cannot be realized.
