A garden landscape plant pruning device

Abstract

This invention relates to the field of pruning devices, and discloses a garden landscape plant pruning device, including a connecting steel pipe. A gasoline engine is fixedly installed at the top of the connecting steel pipe, and a mounting housing is fixedly installed at the bottom of the connecting steel pipe. A handle is fixedly installed on the outer surface of the connecting steel pipe. This invention allows the cutting rope to be wound from the drum by manually pulling it. After pulling to the desired length, the spring force causes a locking block to engage with an arc-shaped block in the groove of the chuck. At this time, the position of the drum is restricted. By manually rotating the clamping nut, the chamfer of its inner wall abuts against the conical angle of the outer wall of the elastic sleeve. The elastic sleeve then contracts, clamping the cutting rope through the anti-slip texture of its inner wall. The clamping nut is tightened when it can no longer be turned. This device allows for flexible adjustment of the cutting rope length according to the spacing of the plants, and the operation is simple and convenient for operators.
