[0029] Embodiment

[0030] Please refer to Figure 1 and Figure 2In some embodiments of the present application, pruning apple trees can control the growth rate of apple trees, promote the healthy growth of trees, enhance resistance, and keep away from the invasion of pests and diseases. At the same time, pruning can also make the nutrition more concentrated, make the fruit more full and better taste. Finally, pruning can also help the management of the orchard, make the orchard more ventilated and light, reduce the consumption of nutrients, and store energy for the growth of next year. The pruning device for apple planting is composed of a static cutter 5, a dynamic cutter 4, an extension pipe 1, a dynamic handle 10, a static handle 9 and a traction rope 8. The static cutter 5 is installed on the outer side wall of the first end of the extension pipe 1. The static cutter 5 is rotatably connected to the bottom of the dynamic cutter 4 by a bolt. The dynamic cutter 4 and the static cutter 5 can rotate relative to each other at the bolt connection. An arc-shaped sliding groove 6 is formed on the surface wall of the static cutter 5 (the sliding groove 6 penetrates the static cutter 5). The dynamic cutter 4 is provided with a sliding piece 7 which is clamped into the sliding groove 6. When the sliding piece 7 slides in the sliding groove 6, the dynamic cutter 4 can make a corresponding rotating action. When the sliding piece 7 slides towards the lower part of the sliding groove 6, the dynamic cutter 4 rotates towards the static cutter 5 to make a pruning action. When the sliding piece 7 slides towards the upper part of the sliding groove 6, the dynamic cutter 4 rotates away from the static cutter 5. The second end of the extension pipe 1 is provided with the static handle 9. The static handle 9 and the top of the dynamic handle 10 can be rotatably connected by a bolt. The static handle 9 and the dynamic handle 10 can rotate relative to each other at the bolt connection. One end of the traction rope 8 is connected to the end of the sliding piece 7, and the other end of the traction rope 8 is connected to the dynamic handle 10. The orchard technician can also hold the extension pipe 1 to the area to be pruned. One hand can hold the extension pipe 1, and the other hand can hold the static handle 9 and the dynamic handle 10 at the same time. Then the static cutter 5 and the dynamic cutter 4 are stretched to the position corresponding to the height of the apple tree branches. The branches are clamped between the dynamic cutter 4 and the static cutter 5. Then the dynamic handle 10 is held tightly to make the dynamic handle 10 rotate towards the static handle 9. The dynamic handle 10 pulls the traction rope 8 during the rotating process. The traction rope 8 pulls the sliding piece 7, and the sliding piece 7 slides towards the lower part of the sliding groove 6. The dynamic cutter 4 rotates towards the static cutter 5 to cut off the branches. The pruning device for apple planting of the present application has a small size, is easier to be stored and does not occupy too much space. It is light in weight, can reduce transportation cost, and is more convenient to move frequently in the apple tree garden to prune branches of apple trees in different positions. The structure is simple, which reduces the operation difficulty and training cost. The height is adjustable, which can prune branches of apple trees in different heights without high-altitude operation, and is safer.

[0031] Please refer to Figure 1 , Figure 2 Figure 7 and Figure 8The extension pipe 1 is composed of a first telescopic pipe 2 and a second telescopic pipe 3. One end of the first telescopic pipe 2 is connected to the static handle 9, and one end of the second telescopic pipe 3 is connected to the static cutter 5. The first telescopic pipe 2 is sleeved outside the second telescopic pipe 3. A guide groove is formed in the inner side wall of the first telescopic pipe 2 along the extension direction, and a guide block matched with the guide groove is installed on the outer side wall of the second telescopic pipe 3, so as to ensure that the limiting assembly can slide along the direction of the plurality of first limiting holes 19. The limiting assembly is clamped into the first limiting hole 19, which can limit the continuous relative sliding of the first telescopic pipe 2 and the second telescopic pipe 3. After the orchard technician removes the limitation of the limiting assembly, the first telescopic pipe 2 and the second telescopic pipe 3 can continue to slide relative to each other, so that the orchard technician can cooperate the limiting assembly with the corresponding first limiting hole 19 to adjust the length of the extension pipe 1 suitable for different application scenarios, for example, the length of the extension pipe 1 can be reduced during transportation to facilitate storage.

[0032] The limiting assembly is composed of a limiting piece 17 and a first return spring 18. The first return spring 18 is installed in the mounting hole 16, the outer side wall of one end of the first return spring 18 is connected to the inner side wall of the mounting hole 16, and the inner side wall of the other end of the first return spring 18 is connected to the limiting piece 17. When the limiting piece 17 is outside the first limiting hole 19, the first return spring 18 is in a corresponding compressed state. After the first telescopic pipe 2 and the second telescopic pipe 3 are moved relative to each other until the limiting piece 17 moves to the first limiting hole 19, the first return spring 18 applies a pushing force to the limiting piece 17 to push the limiting piece 17 into the first limiting hole 19, so that the first return spring 18 restores the deformation. Although one end of the limiting piece 17 is clamped into the first limiting hole 19, the other end of the limiting piece 17 is at least partially located outside the mounting hole 16. When the length of the extension pipe 1 is adjusted again, the part of the limiting piece 17 outside the mounting hole 16 is pulled, the other end of the limiting piece 17 is pulled out of the first limiting hole 19, and then the first telescopic pipe 2 and the second telescopic pipe 3 are moved relative to each other again until the limiting piece 17 moves to the corresponding first limiting hole 19.

[0033] Please refer to Figures 4 to 6In some embodiments of the present application, the handgrip 10 is provided with a winding groove 14, a winding roller 13 is rotatably installed on the inner side wall of the winding groove, one end of the traction rope 8 is connected to the surface wall of the winding roller 13, and the forward rotation of the rotating wheel 15 can drive the winding roller 13 to rotate forward to wind the traction rope 8 on the winding roller 13. The reverse rotation of the rotating wheel 15 can release the traction rope 8 wound on the winding roller 13. When the constraint assembly constrains the rotating wheel 15, the rotating wheel 15 cannot rotate, so the length of the traction rope 8 cannot be adjusted. When the constraint assembly does not constrain the rotating wheel 15, the rotating wheel 15 can rotate, so the length of the traction rope 8 can be adjusted. When the orchard technician needs to cut the branches of the apple tree at a higher position, the length of the extension pipe 1 is increased, the constraint of the constraint assembly on the rotating wheel 15 is cancelled, the corresponding number of rotations of the rotating wheel 15 is controlled in reverse, the corresponding length of the traction rope 8 is increased, and finally the constraint of the constraint assembly on the rotating wheel 15 is released. The orchard technician can perform cutting work at a higher height. When the orchard technician needs to cut the branches of the apple tree at a lower position, the length of the extension pipe 1 is reduced, the constraint of the constraint assembly on the rotating wheel 15 is cancelled, the corresponding number of rotations of the rotating wheel 15 is controlled in forward, the corresponding length of the traction rope 8 is reduced, and finally the constraint of the constraint assembly on the rotating wheel 15 is released. The orchard technician can perform cutting work at a lower height, and the reduced length of the extension pipe 1 makes it more convenient for the orchard technician to operate.

[0034] For example, the rotating wheel 15 is installed at the end of the winding roller 13, the rotating wheel 15 can drive the winding roller 13 to rotate, the second limiting hole 22 is formed on the rotating wheel 15, a plurality of third limiting holes 21 are formed on the handgrip 10, and the second limiting hole 22 on the rotating wheel 15 can be aligned with the third limiting holes 21 on the handgrip 10. When the orchard technician adjusts the length of the traction rope 8, the limiting rod 12 is taken out of the corresponding third limiting hole 21 and the second limiting hole 22, then the rotating wheel 15 is rotated for a corresponding number of times, the limiting rod 12 is clamped into the second limiting hole 22 and the corresponding third limiting hole 21, and the rotating wheel 15 is constrained. The surface wall of the limiting rod 12 can have a certain elasticity (such as a rubber layer), and the limiting rod 12 is more stable after being clamped into the second limiting hole 22 and the corresponding third limiting hole 21, thereby improving the cutting efficiency of the orchard technician.

[0035] The sliding member 7 can be rod-shaped, the sliding member 7 passes through the moving cutter 4 and the sliding groove 6 in sequence, and the two ends of the sliding member 7 can be fixed by nuts to avoid the problem of falling out of the sliding groove 6. The sliding member 7 can reciprocate in the sliding groove 6, and the moving cutter 4 can rotate towards or away from the stationary cutter 5.

[0036] Please refer to Figure 3 and Figure 9In some embodiments of the present application, one end of the reset member 11 is rotatably connected to the end of the sliding member 7 (the one end of the reset member 11 can be sleeved on the outside of the sliding member 7), and the other end of the reset member 11 extends into the extension pipe 1. The outside of one end of the second reset spring 20 is connected to the inside wall of the extension pipe 1, and the inside of the other end of the second reset spring 20 is connected to the reset member 11. When cutting the branch, the moving cutter 4 rotates towards the static cutter 5, the reset member 11 slides downwards with the sliding member 7, the reset member 11 presses the second reset spring 20, and the second spring is in a compressed state. After cutting is completed, the second reset spring 20 pushes the reset member 11 to drive the sliding member 7 to slide upwards, so that the moving cutter 4 and the static cutter 5 are separated, facilitating the next cutting work.

[0037] In summary, the embodiment of the present application provides a pruning device for apple planting, which has small volume, is easier to be stored and saved, and does not occupy too much space; has light weight, can reduce transportation cost, and is more convenient to frequently move in an apple tree garden and prune branches of apple trees at different positions; has simple structure, reduces operation difficulty and training cost; is height-adjustable, can prune branches of apple trees at different heights, does not need high-altitude operation, and is safer.
