[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] A pruning machine for mandarin orange branches, such as Figures 1-5 As shown, the device includes a handle 1 and a sliding rod 2 slidably connected to the handle 1. A protective cover 3 is fixedly connected to the sliding rod 2 to prevent the saw blade 5 from injuring people or damaging branches on other branches. A positioning rod 4 is rotatably connected to the protective cover 3, and a saw blade 5 is fixedly connected to the positioning rod 4 for cutting branches. The protective cover 3 is equipped with a drive assembly that drives the saw blade 5 to rotate and a branch-pulling assembly for pushing aside branches. The drive assembly includes a fixed plate 6 fixedly connected to the protective cover 3, several connecting rods 7 connected to the fixed plate 6, and a motor 8 fixedly connected to the several connecting rods 7. The output shaft of the motor 8 is fixedly connected to the positioning rod 4. The protective cover 3 has a sliding groove 9 for the positioning rod 4 to slide. The several connecting rods 7 are all slidably connected to the fixed plate 6 and are sleeved between the fixed plate 6 and the motor 8. With a compression spring 10, when pruning branches, the saw blade 5 can first be brought into contact with the branch to be pruned, and then the handle 1 can be pushed. The positioning rod 4 will slide in the groove 9 and drive the dispersing component to push away the branches near the branch to be pruned. At this time, the compression spring 10 is in a compressed state. Then the motor 8 is turned on, and the motor 8 drives the positioning rod 4 to rotate and drives the saw blade 5 to rotate for branch pruning. After the cutting is completed, the motor 8 is turned off and the saw blade 5 is moved away from the branch. At this time, the compression spring 10 returns to its original state and drives the positioning rod 4 to return to its original state. The dispersing component changes from an extended state to a retracted state to protect the saw blade 5. In this way, when pruning orange trees, the driving component and the dispersing component work together to push away the branches near the branch to be pruned and prevent the branches from getting close to the saw blade 5 during pruning, thereby ensuring fruit yield and quality.

[0024] like Figure 1 , Figure 2 , Figure 4 As shown, the disengaging assembly includes a positioning frame 11 fixedly connected to both sides of the protective cover 3, a positioning block 12 rotatably connected to the positioning frame 11, and a disengaging plate 13 fixedly connected to the positioning block 12. Torsion springs 14 are fixedly connected to both sides of the positioning block 12, and the other ends of the two torsion springs 14 are fixedly connected to both sides of the positioning frame 11. The protective cover 3 is provided with a triggering element that drives the disengaging plate 13 to rotate. The triggering element includes two sliding plates 15 slidably connected to the protective cover 3 and pull ropes 16 fixedly connected to both sides of the sliding plates 15. The other ends of the two pull ropes 16 are fixedly connected to adjacent disengaging plates 13. On plate 13, sliding plate 15 is rotatably connected to positioning rod 4. When saw blade 5 contacts the branch to be pruned and the handle 1 is pushed, positioning rod 4 will slide in groove 9 and drive positioning frame 11 to slide. Then, pull rope 16 will pull the two side plates 13. At this time, the two side plates 13 will open and push away the branches near the branch. At this time, torsion spring 14 is in a deformed state. After the cutting is completed, compression spring 10 resets and drives positioning rod 4 to reset. Pull rope 16 no longer pulls plate 13. Torsion spring 14 starts to reset and drives plate 13 to reset, thus protecting saw blade 5.

[0025] like Figure 1 , Figure 5 As shown, a groove 17 is provided on the sliding rod 2, and a wedge block 18 is fixedly connected in the groove 17. A trigger block 19 is slidably connected to the handle 1. A tension spring 20 is fixedly connected between the bottom side of the sliding rod 2 and the bottom side of the handle 1. When the motor 8 is turned on, the trigger block 19 can be pressed simultaneously, so that the trigger block 19 contacts the inclined surface of the wedge block 18. When the trigger block 19 is pressed further, the sliding rod 2 will be pushed forward by the wedge block 18. At this time, the spring of the pull rope 16 is in a stretched state, so that the saw blade 5 always keeps in contact with the branch for pruning. In this way, when pruning the branch, there is no need to extend the arm again, so that the saw blade 5 always keeps in contact with the branch, thus making the pruning more stable. After pruning, simply release the trigger block 19, the tension spring 20 returns to its original position, and the wedge block 18 starts to push the trigger block 19 to return to its original position for the next use.

[0026] like Figure 5 As shown, limit blocks 21 are fixedly connected to both sides of the trigger block 19, which can prevent the wedge block 18 from pushing the trigger block 19 when the tension spring 20 is reset, causing the trigger block 19 to disengage and pop out, and no longer contact the grip 1.

[0027] like Figures 3-4 As shown, the protective cover 3 is fixedly connected to brushes 22 on both sides of the saw blade 5. It can clean the surface of the saw blade 5 and prevent sawdust generated during trimming from entering the protective cover 3. This prevents the sawdust particles from scratching or abrading the surface of the saw blade 5 when they come into contact with it, which would seriously affect the sharpness and service life of the saw blade 5.

[0028] Working principle: When pruning branches, first bring the saw blade 5 into contact with the branch to be pruned, then continue pushing the handle 1. The positioning rod 4 will slide in the groove 9 and drive the positioning frame 11 to slide. Then, the pull rope 16 will pull the two side plates 13, which will open and push aside the branches near the branch. At this time, the torsion spring 14 and the compression spring 10 are both in a deformed state. Then, turn on the motor 8. The motor 8 drives the positioning rod 4 to rotate and drives the saw blade 5 to rotate for branch pruning. Simultaneously, the trigger block 19 can be pressed, causing the trigger block 19 to contact the inclined surface of the wedge block 18. When the trigger block 19 is pressed, the sliding rod 2 will be pushed forward by the wedge block 18, so that the saw blade 5 always fits against the branch for pruning. After the cutting is completed, the motor 8 is turned off and the saw blade 5 is moved away from the branch. At this time, the compression spring 10 resets and drives the positioning rod 4 to reset. The pull rope 16 no longer pulls the lever plate 13, and the torsion spring 14 begins to reset and drives the lever plate 13 to reset, thus protecting the saw blade 5.

[0029] This allows the driving and dispersing components to work together to separate branches near the trunk during pruning, preventing them from getting close to the saw blade 5 and ensuring fruit yield and quality. Furthermore, the saw blade 5 remains in contact with the trunk without needing to extend the arm during pruning, making the pruning process more stable.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
