In addition, some ornamental trees need to be pruned for beauty and maintenance. As the trees grow taller, it is difficult for humans to reach the branches that need to be pruned. It must be done with the help of tools.
When the branches of trees are high, it is necessary to climb ladders and other tools, which is inconvenient to operate and has certain dangers, which makes the work efficiency of gardening workers low.

The invention provides a telescopic branch pruning device. The telescopic branch pruning device comprises a holding rod, an ejecting rod, a first shearing knife, a second shearing knife, a first transmission mechanism and a second transmission mechanism; a sliding cavity is formed in the holding rod; the first transmission mechanism comprises a sliding frame, a first rolling wheel, a second rolling wheel and a first transmission belt; a gear is installed on the second shearing knife, a first engaging groove is formed in the periphery of the first transmission belt; the first engaging groove is engaged with the gear in the aspect of the shape; the second transmission mechanism comprises a third rolling wheel, a fourth rolling wheel, a handle and a second transmission belt; a second engaging groove is formed in the fourth rolling wheel, and the second transmission belt and the first transmission belt are engaged through the first engaging groove and the second engaging groove; a clamping-in piece is arranged on the ejecting rod, and the holding rod is provided with a plurality of clamping-in holes detachably matched with the clamping-in piece. By means of the telescopic branch pruning device, the distance between a shearing mechanism and the holding rod can be conveniently and fast adjusted, and tree branches can be conveniently sheared through the handle.
Description
technical field [0001] The invention relates to the technical field of garden operating equipment, in particular to a retractable branch pruning device. Background technique [0002] In the process of tree growth, new branches and leaves will continue to be produced. Some trees must prune the bottom branches and leaves. Too many branches and leaves will consume a lot of nutrients. Cutting off excess branches will reduce consumption and help the growth of the trunk. In addition, some ornamental trees need to trim some branches for the sake of beauty and maintenance. As the trees grow taller, it is difficult for people to reach the branches that need to be trimmed, and tools must be used to complete it. When the branches of trees are higher, tools such as climbing ladders are needed to carry out the operation, which is inconvenient and dangerous, which makes the work efficiency of the gardening workers lower. Contents of the invention [0003] Based on the technical problem...
