AI Technical Summary
Technical Problem
Conventional chainsaws are prone to motor or saw blade damage under overload conditions. Traditional protection mechanisms require manual shutdown and electronic components are easily damaged, making them inconvenient to use.
Method used
The cutting protection module is linked with the mechanical brake protection module. The transmission is disconnected in case of overload through active and passive braking structures, and automatic shutdown is achieved in combination with the electronic brake protection module.
Benefits of technology
It achieves automatic braking in overload conditions, protecting the motor and user safety, quickly restoring use, and preventing damage to electronic components.

Abstract
本实用新型涉及锯切设备技术领域，具体公开了一种链锯的保护结构，包括机身与设置在机身内的切割保护模块、机械刹车保护模块，所述切割保护模块包括主动轮、从动轮、第一弹性体，所述主动轮在沿某一方向转动时可带动从动轮转动，当链轮单元受到的切割力大于第一弹性体的力时，从动轮脱离与主动轮的传动配合；所述机械刹车保护模块包括刹车盘、第二弹性体、拨动单元、控制单元；所述拨动单元与刹车盘接触时可克服第二弹性体的力使得刹车盘不与从动轮接触，所述拨动单元脱离刹车盘时，第二弹性体带动刹车盘接触从动轮并使得从动轮脱离主动轮。本实用新型实现主动与被动的刹停，同时维持电机运作，便于快速重新使用。
