[0026] The two drive blocks 38, the connecting frame 39 and the limiting plug rod 391 can be driven to move, so that one end of the limiting plug rod 391 can be removed from the inside of the limiting slot 392, so that the circular mounting plate 32 can be taken out from the inside of the mounting frame 31, and the circular mounting plate 32 and the trimming machine body 4 can be rotated ninety degrees to adjust the working orientation of the trimming machine body 4, and then the circular mounting plate 32 is moved to the inside of the mounting frame 31 again, and the rectangular limiting slot 33 on the left side of the circular mounting plate 32 is sleeved on the outside of the rectangular positioning block 34. Through the setting of the rectangular limiting slot 33 and the rectangular positioning block 34, it is convenient to preliminarily limit the circular mounting plate 32, and then insert one end of the limiting plug rod 391 into the inside of the limiting slot 392 in the same way, so as to facilitate the fixed installation of the circular mounting plate 32. At this time, after rotating ninety degrees, the trimming machine body 4 is convenient for vertical operation.

[0027] Embodiment 2:

[0028] like Figure 1-5 As shown, the four corners of the bottom of the base 1 are equipped with moving wheels 11, and the trimming height adjustment mechanism 2 includes a limit cover 21. The bottom of the limit cover 21 is fixedly connected to the top of the base 1. A lifting plate 27 is provided inside the limit cover 21. Adjustment rods 26 are fixedly connected to both sides of the top of the lifting plate 27. The number of the adjustment rods 26 is two. The top of the limit cover 21 is fixedly connected to the installation cover 22. The installation cover 22 is provided with an adjustment plate 25. The top ends of the two adjustment rods 26 extend to the inside of the installation cover 22 and are fixed. Fixedly connected to both sides of the bottom of the adjustment plate 25, a motor 23 is fixedly installed on the top of the inner wall of the mounting cover 22, and a reciprocating screw rod 24 is fixedly connected to the output end of the motor 23. The bottom end of the reciprocating screw rod 24 is rotatably connected to the middle of the top of the limit cover 21. The middle part of the adjustment plate 25 is threadedly sleeved on the outer wall of the reciprocating screw rod 24.

Guide blocks 28 are fixedly connected to both sides of the lifting plate 27, and the outer wall of the guide block 28 is slidably connected to the inside of the guide groove 29.

[0029] In this embodiment, no matter the trimming machine body 4 is working horizontally or vertically, the cooperation among the motor 23, the reciprocating screw rod 24, the adjustment plate 25 and the adjustment rod 26 facilitates the lifting plate 27 to move vertically inside the limit cover 21. At the same time, the two sides of the lifting plate 27 drive the guide blocks 28 to slide inside the guide grooves 29. The cooperation between the guide blocks 28 and the guide grooves 29 facilitates the vertical guidance of the lifting plate 27 to maintain the stability of the lifting plate 27 when moving. When the lifting plate 27 moves, the lifting plate 27 can drive the trimming machine body 4 to move vertically through the mounting frame 31 and the circular mounting plate 32, so as to facilitate the adjustment of the height of the trimming machine body 4 when working.

[0030] In summary, if Figure 1-5As shown, the tea tree pruning machine for a tea garden is moved to the vicinity of the tea tree to be pruned when in use, and the pruning machine body 4 is located above the tea tree. At this time, the reciprocating screw rod 24 is driven to rotate by the output end of the motor 23, and the reciprocating screw rod 24 drives the adjustment plate 25 to move inside the mounting cover 22. The adjustment plate 25 drives the lifting plate 27 to move vertically inside the limit cover 21 through the adjusting rod 26. At the same time, the lifting plate 27 drives the pruning machine body 4 to descend to the specified pruning height through the mounting frame 31 and the circular mounting plate 32, and then the pruning machine body 4 is started, and the device is pushed to move at the same time, so that the pruning machine body 4 moves horizontally to perform a long-distance pruning operation on the tea tree.

[0031] When the side branches of the tea tree need to be pruned, the staff can rotate the two-way screw rod 37 through the knob 36, so that the two-way screw rod 37 drives the two driving blocks 38 to slide symmetrically inside the protective cover 35, and the two driving blocks 38 simultaneously drive one end of the limiting plug rod 391 to move out from the inside of the limiting slot 392 through the connecting frame 39. At this time, the circular mounting plate 32 is taken out from the inside of the mounting frame 31, and the circular mounting plate 32 and the pruning machine body 4 are rotated ninety degrees, so as to adjust the working orientation of the pruning machine body 4, and then the circular mounting plate 32 is moved to the inside of the mounting frame 31 again, and the rectangular limiting groove 33 on the left side of the circular mounting plate 32 is sleeved on the outside of the rectangular positioning block 34. At this time, the knob 36 and the two-way screw rod 37 are rotated in the opposite direction, and the limiting plug rod 391 is driven to move in the same way, so that one end of the limiting plug rod 391 is inserted into the inside of the limiting slot 392, and then the circular mounting plate 32 is fixedly installed in the inside of the mounting frame 31. At this time, the pruning machine body 4 is rotated ninety degrees to perform vertical operation. Figure 5 As shown in the figure, the pruning machine body 4 is driven to move vertically back and forth in the same manner, and the device is pushed to move at the same time, thereby pruning the side branches of the tea tree.
