Grass cutting and pruning machine

Abstract

The invention relates to a grass cutting and pruning machine, which comprises a main machine body and a baseplate cutting component, wherein the main machine body comprises a housing with a handle; a trigger for controlling make-and-break of a switch is arranged outside the housing; rechargeable batteries and a motor which is electrically connected with the rechargeable batteries through the switch are arranged in the housing; the motor outputs power to the baseplate cutting component via a motor gear, an intermediate gear, a gearwheel eccentric wheel; the baseplate cutting component comprises a baseplate and a tool bit component; the gearwheel eccentric wheel is movably mounted with a gearwheel shaft in the axial direction; a reset spring for the reset of the gearwheel eccentric wheel is arranged in the main machine body; a tension spring is mounted between the baseplate and the tool bit component. The machine has the advantages that during replacement of blades, the blades are mounted on the baseplate firstly and are mounted in the main machine body together with the baseplate, then the reset spring and the tension spring are utilized, so that when the machine rotates, the gearwheel eccentric wheel can be automatically mounted in an eccentric wheel retaining ring and the operation is safe, sanitary, convenient and fast.

Description

technical field [0001] The invention relates to a garden tool, in particular to a grass trimmer. Background technique [0002] Numerous gardening tools have brought great help to gardening workers, and the grass trimmer is a gardening tool used for trimming the lawn or trimming branches. However, when the existing mowing and pruning dual-purpose trimmers change cutters, its large gear eccentric wheel will withstand the eccentric wheel retaining ring on the cutter head assembly, so that the large gear eccentric wheel cannot move axially. Need to move upper blade by hand, make the eccentric wheel retaining ring slowly aim at the big gear eccentric wheel and just can put on the blade, change the blade every time and all dirty and unsafe, also wasted a large amount of time. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art and provide a grass cutting and pruning machine. [0004] The technical solution to rea...

Problems solved by technology

However, when the existing mowing and pruning dual-purpose trimmers change cutters, its large gear eccentric wheel will withstand the eccentric wheel retaining ring on the cutter head assembly, so that the large gear eccentric wheel cannot move axially. It is necessary to move the upper blade by hand so that the eccentric wheel retaining ring is slowly aligned with the large gear eccentric wheel to install the blade. Every time the blade is changed, it is dirty and unsafe, and a lot of time is wasted
