Pruner

The invention discloses a pruner provided with a combination transmission structure of a planetary gear train and a bevel gear train. The planetary gear train and the bevel gear train are both assembled in a gear case; the planetary gear train comprises a bevel pinion, a pinion shaft of the bevel pinion is assembled with a driving plate assembly, the driving plate assembly is assembled in a planetary gear ring, the driving plate assembly is provided with four planetary gear shafts, each planetary gear shaft is sleeved by a planetary gear, and a motor pinion is assembled among the four planetary gears; the bevel gear train comprises a bull gear assembled on a bull gear shaft, isolating pieces are arranged among eccentric blocks, and the eccentric blocks and the isolating pieces are all arranged in blade mounting holes. Through the above way, problems that an existing hedge pruner is small in cutting torque and loud in noise or branch jam occurs when the existing hedge pruner cuts branches are solved, the prune
