Description

Technical Field

[0001] The utility model relates to the technical field of gardening, in particular to a tree branch trimmer. Background Art

[0002] A beautiful natural environment and recreational space created by using engineering technology and artistic means in a certain area, through transforming the terrain, planting trees, flowers and plants, constructing buildings and arranging garden paths, is called a garden. A variety of bright flowers and plants can be planted in a garden, so that pedestrians can not only rest when walking in the garden, but also enjoy the beautiful scenery. The branches and leaves of the trees need to be maintained and pruned regularly to maintain the overall beauty of the trees.

[0003] According to a branch pruning machine disclosed in patent search publication number CN219812599U, its beneficial effects are as follows: workers can hold the gripping tube in their hands, and when pruning tea tree branches, they can directly extend the long board and the two vertical boards into the tea tree without bending over. The L-shaped structure formed by the long board and the two vertical boards can hook the branches. After the two vertical boards are used to hook the branches, the electric push rod piston rod is extended outward, so that the cutting knife head is inserted between the two vertical boards. The cutting knife can cut the branches during the movement to complete the pruning of the tea tree, which is more convenient for workers to work and avoids back pain caused by long-term bending over when pruning branches.

[0004] When performing daily maintenance and pruning of tree branches, a climbing ladder is needed to increase the height, and corresponding pruning tools are carried at the same time to perform the operation, which limits the function of the operation, makes it relatively simple, and makes the pruning operation difficult.
