[0002] A hedge trimmer, also known as a hedge shear, is suitable for professional pruning in aspects such as tea pruning, parks, courtyards, roadside hedges and other landscaping. It relies on a small gasoline engine as the power to drive the blade to cut and rotate. At present, some hedge trimmers are also powered by electricity. The main structure includes a knife bar assembly, a handheld end and a power assembly. And the knife bar assembly can be classified into straight knives and arc knives, and there are also various lengths, which are applied to different working scenarios.

[0003] After retrieval, a hedge trimmer with the publication number of CN 206791070 U includes a machine body. A main handle is fixedly connected to the machine body. A knife handle is fixedly connected to one end of the machine body away from the main handle. A blade is slidably connected to one side of the knife handle. A secondary handle and a baffle are connected to the knife handle. The secondary handle is located between the baffle and the machine body. A scraping plate is hinged to the knife handle. The scraping plate is slidably connected to the side of the baffle facing away from the knife handle. An elastic assisting member is fixedly connected to one end of the scraping plate close to the secondary handle. A first elastic member is fixedly connected to the secondary handle. One end of the first elastic member away from the secondary handle is fixedly connected to a pressing piece. The pressing piece moves towards the end close to the secondary handle and abuts against the end of the elastic assisting member away from the scraping plate, achieving the purpose of effectively cleaning the branches and leaves on the baffle.

[0004] However, there are still some deficiencies in the above-mentioned hedge trimmer during use. The handle is fixedly installed on the machine body, making it difficult to adjust according to the actual usage situation of the operator. Moreover, during use, the angle of the handle cannot be adjusted either, resulting in the operator's hand being frustrated and difficult to apply force when using the hedge trimmer. When pruning some inclined or spherical hedges, the operator often needs to hold the hedge trimmer in a very uncomfortable posture for pruning operations, increasing the operator's operation difficulty and physical exertion.
