[0028] When the device is running, first move the support long rod 1, place the object to be trimmed vertically in the middle of the support block 2 and the trimming knife 5, and then pull the pull rope 8 outside the support long rod 1. Under the combined support of the fixed pulley 10 and the movable pulley 9, drive the pulling block 7 inside the trimming knife 5 to move counterclockwise, so that the trimming knife 5 moves counterclockwise at the same time, making the trimming knife 5 move towards the blade 4 for cutting, achieving the effect of vertical trimming. Then, by pulling the pull rope 8 inside, under the combined support of the fixed pulley 10 and the movable pulley 9, drive the pulling block 7 outside to move clockwise to reset the trimming knife 5, facilitating the stability of the device for the next cutting use. At the same time, by setting the drive connection component as the pull rope 8, the overall portability of the device can be improved, facilitating its movement and trimming at higher positions. At the same time, under the adjustment of the running direction of the pull rope 8 by the fixed pulley 10, the stability of the connection angle with the movable pulley 9 is ensured, and with the labor-saving support of the movable pulley 9, the labor-saving operation of the device during trimming and resetting can be improved, thereby improving the actual performance of the device. The limit block 11 provides a limit support effect for the movement of the pull rope 8. Finally, with the sawtooth 3 for support, the usage mode of the device can be increased.
[0029] As Figures 1 - 6 shown, a support groove 16 is opened inside the support long rod 1, and the support groove 16 runs through the upper and lower ends of the support long rod 1, and the trimming knife 5 is rotatably installed on the inner wall of the support groove 16 through a rotating rod 6.
[0030] Under the rotational support of the support groove 16 and the rotating rod 6, the stability of the rotation position of the trimming knife 5 is ensured. At the same time, under the storage support of the support groove 16 for the rotational reset of the trimming knife 5, it is convenient to collect and place the trimming knife 5, and at the same time, the rotation angle of the trimming knife 5 is increased, improving the trimming specification of the device.
[0031] As Figures 1 - 6 shown, sliding grooves 17 are opened on both sides of the middle part of the inner wall of the support groove 16, guide rods 14 are installed on the upper and lower sides of the inner wall of the sliding groove 17, and a sliding block 13 is slidably connected to the outside of the guide rod 14.
[0032] The sliding block 13 is rotatably connected to a rotating column 12, and the rotating column 12 is inserted into the movable pulley 9.
[0033] When the movable pulley 9 rotates, it drives the rotating column 12 to rotate at the same time. Under the rotational support of the sliding block 13 and the height movement guidance and support of the guide rod 14 for the sliding block 13, the rotating column 12 and the movable pulley 9 can move in height while rotating, thereby ensuring its labor-saving support effect.
[0034] Embodiment 2: A device for trimming orange tree branches, as Figures 1 - 6 shown, there are two annular grooves inside the movable pulley 9, and the two annular grooves are respectively in belt drive connection with the two pull ropes 8.
[0035] Under the misaligned support of the annular grooves on both sides inside the movable pulley 9, it can be connected to the two pull ropes 8 simultaneously, ensuring the stability of the positions of the two pull ropes 8 during movement. And with the support of the length of the pull ropes 8 themselves, it is ensured that when moving in height, it does not affect the movement operations of the two pull ropes 8.
[0036] As Figures 1 - 6 shown, a rotating column 12 is inserted in the middle of the outer side of the fixed pulley 10, and the rotating column 12 is rotatably installed on both sides of the inner wall of the support groove 16.
[0037] Under the rotational support at the fixed position of the rotating column 12 on one side of the fixed pulley 10, the stable rotational support of the fixed pulley 10 is ensured, thereby providing stable support for the angle adjustment of the pull rope 8.
[0038] As Figures 1 - 6 shown, an external thread 15 is installed on the upper half of the outer side of the support long rod 1, and the external thread 15 is connected to the outer support cylinder.
[0039] By using the outer support cylinder, a rotational connection is made from above the support long rod 1 to ensure the protective support for the components on the upper half of the support long rod 1 and improve the safety during movement.
[0040] Working principle: First, move the support long rod 1, place the object to be trimmed vertically between the support block 2 and the middle of the trimming knife 5. Then, by pulling the pull rope 8 on the outer side of the support long rod 1, under the combined support of the fixed pulley 10 and the movable pulley 9, drive the pulling block 7 inside the trimming knife 5 to move counterclockwise, thereby making the trimming knife 5 move counterclockwise simultaneously, causing the trimming knife 5 to move towards the blade 4 for cutting, achieving the effect of trimming the vertical object. Then, by pulling the inner pull rope 8, under the combined support of the fixed pulley 10 and the movable pulley 9, drive the outer pulling block 7 to move clockwise to reset the trimming knife 5, facilitating the stability of the device for the next cutting use. At the same time, by setting the drive connection component as the pull rope 8, the portability of the overall device can be improved for easy movement and trimming at higher positions. Also, under the adjustment of the running direction of the pull rope 8 by the fixed pulley 10, the stability of the connection and use angle with the fixed pulley 10 is ensured, and with the labor-saving support of the fixed pulley 10, the labor-saving operation during trimming and resetting of the device can be improved, thereby enhancing the actual use performance of the device.
