Abstract

The invention relates to a grass trimmer with a height-adjustable blade. The grass trimmer with the height-adjustable blade comprises a support, a motor with a power output shaft extending downwards and an installment seat arranged at the bottom of the motor, wherein the support is provided with a positioning pin, and the installment seat capable of sliding along the positioning pin up and down is arranged on the support. The grass trimmer with the height-adjustable blade further comprises a first cam, wherein the first cam is rotably fixed on the support, the forwards-protruded outline curve portion of the first cam abuts against the bottom surface of the installment seat, teeth are arranged on the rear portion of the first cam, the power output shaft is provided with a drive gear, and the drive gear is connected with the teeth on the rear portion of the first cam through a clutch. The installment seat can be raised or lowered through controlling of the rotating direction of the cam, and therefore the purpose that the height of the motor and the height of the blade are simultaneously adjusted is achieved. Compared with a single cam, a second cam is arranged to provide more stable and more reliable raising force for an installment plate.
