Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model more clear, the utility model will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.

Example 1:

Please refer to Figures 1-7. The present utility model provides a technical solution: a tea tree pruner, which includes two symmetrical support frames 100. A pruning mechanism 114 is provided between the support frames 100. The pruning mechanism 114 It includes two pruning casings 106 in the middle of the support frames 100. The pruning casings 106 are provided with a gear cavity 111. Two front and rear symmetrical rotation axes 108 are rotatably connected in the pruning casings 106. A motor 107 is fixedly connected to the upper end surface of the casing 106. The motor 107 is dynamically connected to the rotating shaft 108 on the front side. Both rotating shafts 108 are fixedly connected to a circular gear 112 located in the gear cavity 111. Each of the circular gears 112 is meshed with a gear rack 103, which drives the gear rack 103 to be slidably connected to the upper and lower end wall tracks of the gear cavity 111. The gear rack 103 is fixedly connected with a plurality of pruning cutter heads 109. The pruning cutter heads are 109 fast rotation can trim tea trees.
