[0002] In the process of fruit tree garden maintenance, it is often necessary to use pruners to prune fruit trees.

[0003] In the prior art, a Chinese patent with publication number CN210782150U discloses a fruit tree pruner belonging to the field of forestry and fruit industry tools. The pruner comprises a support rod, a movable scissor body, and a static scissor body. The static scissor body is disposed at one end of the support rod, and the middle portion of the movable scissor body is hinged to the support rod. A pull rope is disposed at one end of the movable scissor body. A collar is slidably provided on 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 collar, and a pedal is disposed on the outer wall of the collar. During use, the operator places the branch to be pruned between the movable and static scissor bodies, places the end of the support rod on the ground, and steps downward on the pedal. The pull rope then pulls the movable scissor body, and the branch is cut. The use of foot-operated movement of the movable scissor body facilitates the operator's application of force.
