Description

Technical Field

[0001] This utility model relates to the field of hedge trimmer technology, and in particular to a hedge trimmer with an adjustable angle. Background Technology

[0002] A hedge trimmer is a machine specifically designed for trimming the edges of hedges in landscaping projects. It is suitable for professional trimming in parks, courtyards, roadside hedges, and other garden landscaping applications. By using a hedge trimmer to trim the edges of the green vegetation of the hedges to a suitable and neat shape, the green vegetation can be made more tidy and beautiful.

[0003] For example, patent number CN222707078U discloses a hedge trimmer with adjustable trimming angle, including a hedge trimmer body and a support base. A rotating plate is connected to the bottom of the support base, and threaded rods pass through both sides of the support base and are threadedly connected to the support base. A knob is fixedly connected to one end of the threaded rod, and an insert is rotatably connected to the other end. Slots matching the inserts are provided on both sides of the hedge trimmer body. With this hedge trimmer with adjustable trimming angle, the hedge trimmer body is placed on the rotating plate inside the support base. Rotating the knob causes the insert at one end of the threaded rod to be inserted into the slot on the hedge trimmer body, which provides a good fixing effect. Rotating the knob in the opposite direction causes the insert to be disassembled from the slot, which allows the hedge trimmer body to be disassembled. This makes the disassembly of the hedge trimmer body relatively convenient, thus facilitating maintenance. The angle of the hedge trimmer can be adjusted by rotating the rotating plate.

[0004] While the hedge trimmer in this patent can be adjusted by adjusting the angle of the support structure, the operation is quite laborious because the support structure needs to be carried by hand and it lacks height adjustment and guiding functions. When trimming at a large angle or in a vertical direction, the operation is very limited. In addition, the blade is close to the human body after the angle is adjusted, which poses a certain safety hazard. Utility Model Content
