A second bevel gear 404 is connected to one end away from the rotating rod 402, a first screw rod 405 is provided at one end of the second bevel gear 404 away from the first bevel gear 403, a first threaded block 406 is provided on the first screw rod 405, a second adjusting knob 407 is provided on one side of the top end of the second connecting rod 301, the second adjusting knob 407 is connected to a rotating rod 408, a third bevel gear 409 is provided at one end of the rotating rod 408 away from the second adjusting knob 407, a fourth bevel gear 410 is provided at one end of the third bevel gear 409 away from the rotating rod 408, a second screw rod 411 is connected to the fourth bevel gear 410, a second threaded block 412 is connected to the second screw rod 411, and a moving groove 413 is provided on one side of the first connecting rod 3 and the second connecting rod 301 close to the first adjusting knob 401 and the second adjusting knob 407.

[0018] The main rod 2 is sleeved on the outer side of the bottom end of the first connecting rod 3, the second connecting rod 301 is sleeved on the outer side of the bottom end of the main rod 2, the first threaded block 406 is connected to the nut of the first screw rod 405, the second threaded block 412 is connected to the nut of the second screw rod 411, the first threaded block 406 is fixedly connected to the inside of the first connecting rod 3, the second threaded block 412 is fixedly connected to the inside of the main rod 2, the first bevel gear 403 is meshed with the second bevel gear 404, and the third bevel gear 409 is meshed with the fourth bevel gear 410.

[0019] According to the above embodiment, it should be noted that: when using the pruning knife body 1 to prune branches, the length of the pruning knife body 1 can be adjusted for the value at a higher position by manually turning the first adjustment knob 401 and the second adjustment knob 407.

[0020] The rotation of the first adjusting knob 401 drives the rotating rod 402 to rotate, thereby driving the first bevel gear 403 to rotate, and the second bevel gear 404 meshing with the first bevel gear 403 rotates. At this time, the first screw rod 405 starts to rotate, and the first threaded block 406 connected to the nut of the first screw rod 405 moves up and down on the first screw rod 405. Therefore, at this time, the first connecting rod 3 is moved out or retracted in the main rod 2, and the length of the first connecting rod 3 with the trimming blade 302 is adjusted.

[0021] When the second adjusting knob 407 is rotated, the rotating rod 408 is rotated, and the third bevel gear 409 is rotated at this time, and the fourth bevel gear 410 meshing with the third bevel gear 409 is rotated, driving the second screw rod 411 to rotate, so the second threaded block 412 connected to the nut of the second screw rod 411 moves on the second screw rod 411, thereby driving the main rod 2 to move, so as to adjust the length of the pruning knife body 1 at the hand-held position.

[0022] See also Figure 1-3 As shown, a branch pruning guide device includes two main rods 2 arranged crosswise, a sleeve 201 is provided at the intersection of the two main rods 2, two rotating blocks 202 are provided in the sleeve 201, the rotating blocks 202 are movably connected to the sleeve 201, the rotating blocks 202 are fixedly connected to the main rods 2, a fixed block 5 is provided on the opposite side of the two main rods 2, a spring 501 is provided between the two fixed blocks 5, and a pruning blade 302 is provided on the opposite side of the top of the two first connecting rods 3.

[0023] According to the above embodiment, it should be noted that: by default, when the two main rods 2 are closed, the spring 501 is in a normal state. When it is necessary to prune the branches, the main rods 2 are separated, and the spring 501 is stretched. The resetting of the spring 501 can assist the pruning blade 302 to prune the branches, saving effort.

[0024] In summary, the use process of the device is as follows: when using the pruning knife body 1 to prune branches, the length of the pruning knife body 1 can be adjusted according to the value at a higher position, and the first adjustment knob 401 and the second adjustment knob 407 can be manually turned.

[0025] The rotation of the first adjusting knob 401 drives the rotating rod 402 to rotate, thereby driving the first bevel gear 403 to rotate, and the second bevel gear 404 meshing with the first bevel gear 403 rotates. At this time, the first screw rod 405 starts to rotate, and the first threaded block 406 connected to the nut of the first screw rod 405 moves up and down on the first screw rod 405. Therefore, at this time, the first connecting rod 3 is moved out or retracted in the main rod 2, and the length of the first connecting rod 3 with the trimming blade 302 is adjusted.

[0026] When the second adjusting knob 407 is rotated, the rotating rod 408 is rotated, and the third bevel gear 409 is rotated at this time, and the fourth bevel gear 410 meshing with the third bevel gear 409 is rotated, driving the second screw rod 411 to rotate, so the second threaded block 412 connected to the nut of the second screw rod 411 moves on the second screw rod 411, thereby driving the main rod 2 to move, so as to adjust the length of the pruning knife body 1 at the hand-held position.

[0027] By default, when the two main rods 2 are closed, the spring 501 is in a normal state. When the branches need to be pruned, the main rods 2 are separated and the spring 501 is stretched. The resetting of the spring 501 can assist the pruning blade 302 to prune the branches, saving effort.
