Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings. The described embodiments are only some embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

In order to properly adjust the angle of the cutting edge according to the angle of the new tillering, conveniently remove the new tillering and ensure that the wound of the fruit tree is small. The embodiment discloses a new tiller cleaning scraper of fruit tree trunk, mainly includes scraper head 1, handheld pole 2 and angle adjusting part. The scraper head 1 is provided with two cutting edges which are symmetrically distributed up and down, the scraper head 1 is made of hard metal materials, and the rear end face of the scraper head 1 is provided with a hinged plate I3 and a hinged plate II 4.

The handheld rod 2 is made of hard plastic materials, a cavity for placing the angle adjusting assembly is machined in the handheld rod, a supporting plate 6 is arranged in the middle of the cavity, and a square hole is machined in the supporting plate 6. The rear end of the hand-held rod 2 is defined as an operating handle 7, the external contour of the operating handle 7 is designed to be a curved shape conforming to ergonomics, and an annular groove is processed on the outer side of the rear end of the operating handle 7 and is polished smoothly. The front end of the handheld rod 2 is rotatably connected with the hinged plate I3 through a connecting plate, so that the scraper head 1 can rotate around the axis of the hinged plate I3.
