Description

Technical Field

[0001] The utility model relates to the technical field of fruit tree pruning, in particular to a fruit tree pruner. Background Art

[0002] Fruit tree pruning is a technical measure to cut off part of the nutritional organs of fruit trees in order to adjust the crown structure and renew the branch composition.

[0003] After searching, a Chinese patent discloses a fruit tree pruner (authorization announcement number CN210782150U), which includes a support rod, a movable scissor body and a static scissor body. The static scissor body is arranged at one end of the support rod, and the middle position of the movable scissor body is hinged to the support rod. A pull rope is arranged at one end of the movable scissor body, and a sleeve is provided on the sliding sleeve of the end of the support rod away from the static scissor body. The end of the pull rope away from the movable scissor body is connected to the sleeve, and a pedal is arranged on the outer wall of the sleeve. When in use, the operator places the pruned branches between the movable scissor body and the static scissor body, places the end of the support rod on the ground, and steps on the pedal downward. At this time, the pull rope pulls the movable scissor body, and the branch is cut; the movable scissor is moved by stepping on the foot. The knife body makes it convenient for the operator to apply force. Although this patented technology can be used, when the operator places the pruned branches between the moving scissors body and the static scissors body, places the end of the support rod on the ground, and steps down on the pedal. At this time, the pull rope pulls the moving scissors body and the branches are cut off; the moving scissors body is moved by foot, which makes it convenient for the operator to apply force. However, in the actual application of this patented technology, when the fruit trees grow taller, the branches are located in a position that the scissors cannot reach, so the user needs to climb up with the help of external tools such as ladders to prune. During the climbing process, the staff will be at risk of falling, which may cause injuries to the staff. Utility Model Content
