AI Technical Summary

Technical Problem

During the cutting process of the RF needle, the RF needle is prone to deviation, resulting in poor cutting accuracy and the prior art is difficult to effectively reduce the risk of damage to the RF needle.

Method used

A roll-cutting tool for a radio frequency needle heat shrink tube is designed. By opening an arc groove on the mounting base and pressing the radio frequency needle inside the arc groove through a pressing block with a pressing groove, the position resistance of the radio frequency needle is increased, the bending and offset of the radio frequency needle is avoided, and the position accuracy is improved.

Benefits of technology

It effectively reduces the risk of damage to the RF needle, reduces the deviation of the RF needle, and improves the position accuracy and cutting accuracy of the RF needle.
