Technical Field
[0001] The utility model relates to the technical field of fruit tree pruning equipment, in particular to an agricultural fruit tree pruning device. Background Art
[0002] The branches and leaves of fruit trees will become more and more dense during the growth process. When the branches and leaves of fruit trees are too dense, a large part of the nutrients of the fruit trees will be divided by the excess branches and leaves, and adjacent fruit trees will block each other's sunlight, causing the fruits of the fruit trees to become very small and the yield will decrease accordingly. Therefore, in the process of planting fruit trees, it is necessary to use pruning shears to trim the branches and leaves of the fruit trees.
[0003] In the prior art, an authorized patent with announcement number CN220369102U discloses a fruit tree pruning device, including a hand-held rod and a scissors head, wherein the hand-held rod and the scissors head are connected by a rotating part, the hand-held rod is a hollow rod-shaped structure with an open end, an internal thread 1 is provided inside the hand-held rod, a handle is provided at the end of the hand-held rod, the handle is arranged on the outside of the hand-held rod, an extension rod is provided inside the hand-held rod, and a thread structure 2 cooperating with the internal thread 1 is provided on the extension rod. The utility model is provided with an extension rod that works stably, optimizes the lighting structure, and improves the pruning efficiency.
[0004] However, the above technical solution still has the following shortcomings when in use: the above device can only prune small branches. When encountering thick branches, the device cannot prune, resulting in low applicability of the device. In this regard, we propose an agricultural fruit tree pruning device to solve the above problems. Utility Model Content
