By pulling the pull plate 305, the pull plate 305 drives the baffle plate 303 and the plug rod 304 to move when being pulled, and the spring 302 can also be compressed, so that the adjustment rod 107 can be moved, and the pull plate 305 is released. When the pull plate 305 is released, the spring 302 resets, and the reset of the spring 302 drives the baffle plate 303 and the plug rod 304 to reset, so that the plug rod 304 enters the groove on the adjustment rod 107, thereby fixing the adjustment rod 107. When moving again, pull the pull plate 305 to disengage the insertion rod 304 from the groove of the adjusting rod 107, and move the adjusting rod 107 to adjust the length of the adjusting rod 107 and the pruning slice 108. By adjusting the extension length of the pruning slice 108, the working range of the pruning structure can be increased. As the extension length of the pruning slice 108 increases, the operability of the pruning tool will also be enhanced. The pruner can control the tool more easily, accurately locate and prune the target branch, and reduce the possibility of misoperation. By adjusting the extension length of the pruning slice 108, the pruner can prune in a safer position and avoid climbing a dangerous height or standing in an unstable position.
