AI Technical Summary

Technical Problem

When the handle of the existing pruning machine is pressed, the handle directly presses against the micro switch, which can easily cause overvoltage damage to the micro switch and affect its service life.

Method used

A trigger element is used to activate the micro switch, and the excess force is absorbed by the first elastic element to prevent the trigger element from over-voltage the micro switch and protect the micro switch.

Benefits of technology

It effectively protects microswitches, extends their service life, and prevents damage caused by overvoltage.

Abstract

The application provides a handle assembly, which comprises a static handle, a dynamic handle, a micro switch, a trigger and a first elastic element, wherein the dynamic handle is installed on the static handle and can move relatively to the static handle, the trigger is matched with the micro switch, and the first elastic element is arranged between the trigger and the dynamic handle; when the dynamic handle is pressed, the dynamic handle applies force to the first elastic element, so that the trigger moves under the action of the first elastic element and abuts against the micro switch, thereby triggering the micro switch. Compared with the prior art, the handle assembly of the application triggers the micro switch through the trigger and absorbs the excess force through the first elastic element, so as to effectively ensure that the trigger does not over-press the micro switch, thereby protecting the micro switch and prolonging the service life of the micro switch.
