Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Examples

Referring to fig. 1 and 2, the small self-propelled hedge trimmer of the present embodiment includes a gasoline engine 1, a planetary reducer 2, a disc cutter 3, a plate spring 4, a universal wheel 5, an orientation wheel 6, a frame 7, a handrail 8, and a support frame 9.

The gasoline engine 1 is a horizontal-bar four-stroke air-cooled gasoline engine, power is transmitted between the gasoline engine 1 and the planetary reducer 2 through belt transmission, the gasoline engine 1 and the planetary reducer 2 are fixed on a boss of the frame 7 through bolts, the planetary reducer 2 is connected with the disc cutter 3 through chain transmission, and the planetary reducer 2 is high in transmission efficiency, small in size and weight and convenient to push.
