Description

Technical Field

[0001] The utility model relates to the technical field of hedge trimmers, in particular to an auxiliary operating mechanism for hedge trimmers. Background Art

[0002] Hedge trimmers, also known as hedge shears, are suitable for professional pruning in landscaping such as tea pruning, parks, gardens, and roadside hedges. Hedge trimmers mainly include manual manpower simple machines, handheld small gasoline engines, handheld electric hedge trimmers, and vehicle-mounted large hedge trimmers. Among them, handheld electric hedge trimmers are increasingly widely used due to their light weight, safety, and environmental protection. The weight of a handheld electric hedge trimmer is generally about 5kg. During use, the blade of the hedge trimmer needs to be kept horizontal for greening pruning. When the operator uses it, he needs to bend over to operate it, and the weight of the hedge trimmer is all on his arms. Long-term operation will cause the operator to have back pain, and his arms will find it difficult to bear the weight of the hedge trimmer. Therefore, we propose an auxiliary operating mechanism for a hedge trimmer. Utility Model Content
