[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1-4 In an embodiment of the utility model, a support pole trimming device for fruit tree cultivation includes a first knife body 1 and a second knife body 2 which are hingedly connected. The ends of the first knife body 1 and the second knife body 2 are integrally formed with a connecting plate 3, and a protective frame 4 is hingedly connected to the connecting plate 3. A positioning piece is provided on one end of the protective frame 4 and inserted into the interior of the connecting plate 3. The positioning piece is used to limit the rotation of the connecting plate 3 relative to the protective frame 4. A threaded tube 5 is installed at the other end of the protective frame 4. The internal thread of the threaded tube 5 is connected to a handpiece, and a locking piece for fixing the two groups of protective frames 4 after docking is rotatably installed on one group of the threaded tubes 5.

[0022] The device is unfolded when in use as shown in the figure. The staff holds the handpieces tightly with both hands and squeezes them relative to each other. The handpieces drive the connecting plate 3 and the knife body to move through the protective frame 4 and the positioning piece. The first knife body 1 and the second knife body 2 can cut the branches of fruit trees, etc. When the device is used, the positioning piece is rotated to the outside of the connecting plate 3, the two sets of protective frames 4 are docked and sleeved to the outside of the knife body, the handpieces connected to the two sets of protective frames 4 are parallel, and the two sets of threaded tubes 5 are overlapped and fixed with a locking piece.
