Abstract

The invention discloses a lawn trimmer which is convenient for avoiding obstacles, comprising a device housing, a main controller and a motor are installed inside the device housing, the output shaft of the motor is connected with a telescopic rod, and the lower end of the telescopic rod is connected with There is a rotating disk, the lower end of the rotating disk is connected with a rotating shaft, the lower end of the rotating shaft is connected with a cutting blade, the lower end of the fixed column is provided with a blind hole, the top of the blind hole is equipped with a pressure sensor, and the top of the blind hole is arranged There is a force transmission plate, the upper surface of the force transmission plate is in contact with the pressure sensor, a telescopic block is slidably connected to the blind hole, the telescopic block and the force transmission plate are connected by a return spring, and an alarm is installed on the device housing. Through the settings of the telescopic block, return spring, pressure sensor, main controller and alarm, when an obstacle is encountered, the telescopic block moves upward and compresses the return spring, and the pressure sensor feeds back the signal to the main controller after feeling the pressure. The master controller causes the alarm to sound an alarm.

Description

technical field [0001] The invention relates to the technical field of lawn trimming, in particular to a lawn trimmer which is convenient for avoiding obstacles. Background technique [0002] Lawn trimmer, also known as lawnmower, lawnmower, etc., is a mechanical tool used to trim lawns, vegetation, etc. It is composed of a motor and a blade.
