[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-5 The present invention provides a technical solution: Example 1: An avocado harvesting device includes a U-shaped plate 2. During use, elastic materials such as sponge can be added to the part of the U-shaped plate 2 that comes into contact with the human body. A storage mechanism is provided on one side of the U-shaped plate 2 to store the harvested avocados. Two shoulder straps 15 are fixedly connected to the upper end of the U-shaped plate 2, allowing the U-shaped plate 2 to be worn on the body. A position adjustment mechanism is movably connected to the upper end of the U-shaped plate 2. The upper end of the position adjustment mechanism is connected to a support rod 21, allowing the position and angle of the support rod 21 to be adjusted. A connecting ring 9 is fixedly connected to the outer side of the support rod 21.

[0018] A guide groove 10 extending through the front and back is provided inside the connecting ring 9. A cutter 8 is slidably connected in the guide groove 10. A pulling mechanism is provided on the outside of the support rod 21. One end of the pulling mechanism is connected to the cutter 8. Pulling the pulling mechanism drives the cutter 8 to cut the avocado. The pulling mechanism includes a slip ring 13. The outer side of the slip ring 13 is corrugated. Two pull ropes 12 are fixedly connected to the upper end of the slip ring 13. The upper end of the pull ropes 12 passes through the connecting plate 11 and is fixedly connected to the cutter 8. The connecting plate 11 is fixedly connected to the outside of the connecting ring 9. Pulling the slip ring 13 downwards drives the two pull ropes 12 to move. The movement of the pull ropes 12 drives the cutter 8 to move along the guide groove 10. The moving cutter 8 cuts the avocado and it falls into the net bag 22.

[0019] Two T-shaped limiting rods 7 are fixedly connected to one side of the cutter 8. The T-shaped limiting rods 7 are slidably connected inside the connecting plate 11. A return spring 6 is sleeved on the outside of the T-shaped limiting rods 7. One end of the return spring 6 is fixedly connected to the connecting plate 11, and the other end is fixedly connected to the cutter 8. When the pull rope 12 drives the cutter 8 to move, the cutter 8 will move along the guide groove 10. At the same time, the cutter 8 will drive the two T-shaped limiting rods 7 to move along the connecting plate 11. At this time, the return spring 6 is compressed. When the pull on the slip ring 13 is released, the cutter 8 returns to the initial position along the guide groove 10 under the elastic force of the return spring 6. A collection mechanism is provided at the lower end of the connecting ring 9. The lower end of the collection mechanism is connected to the storage box 1.

[0020] Example 2: Based on Example 1, to ensure that harvested avocados do not pile up, the collection and storage mechanism includes a storage box 1, which is fixedly connected to a U-shaped plate 2. The storage box 1 is arranged vertically through the entire structure, and a first baffle 31 is fixedly connected to its lower end. Several sliding grooves 16 are provided inside the storage box 1, with one end of each groove extending into the external environment. Several sliding rods 18 are provided inside the storage box 1, with both ends of each sliding rod 18 slidably connected to the sliding grooves 16. A second baffle 32 is fixedly connected to one side of each sliding rod 18, with the end of the second baffle 32 away from the sliding rod 18 connected to... Storage box 1 is fixedly connected, and a rotating rod 17 is movably connected to one side of the sliding rod 18. When a certain amount of avocados are stored at the bottom of storage box 1, the sliding rod 18 at the bottom is pulled to move to the outside of storage box 1. The sliding rod 18 can be limited by rotating the rotating rod 17. The movement of the sliding rod 18 causes the second baffle 32 to unfold. The unfolded second baffle 32 can separate the newly fallen avocados from the avocados at the bottom of storage box 1. At the same time, the unfolded second baffle 32 can prevent the newly fallen avocados from falling onto the avocado surface at the bottom of storage box 1.

[0021] The position adjustment mechanism includes a grip 4, with ball-shaped rods 23 fixedly connected to both the upper and lower ends of the grip 4. A connecting cavity 26 is provided inside the grip 4, and a pressing block 25 is slidably connected inside the connecting cavity 26. One end of the pressing block 25 is tapered, and a T-shaped pressing rod 19 is fixedly connected to one end of the pressing block 25. The end of the T-shaped pressing rod 19 away from the pressing block 25 extends into the external environment. A connecting spring 20 is sleeved on the outside of the T-shaped pressing rod 19. One end of the connecting spring 20 is fixedly connected to the T-shaped pressing rod 19, and the other end is fixedly connected to the grip 4. The elastic force of the connecting spring 20 is greater than the elastic force of the two limiting springs 28.

[0022] The outer side of the extrusion block 25 is in contact with two limiting rods 30. The end of the limiting rod 30 away from the extrusion block 25 is provided with several protruding particles, and extends through the grip rod 4 and the spherical rod 23 into the external environment. A second slider 29 is fixedly sleeved on the outer side of the limiting rod 30. The second slider 29 slides in the sliding cavity 27, which is opened in the grip rod 4. A limiting spring 28 is sleeved on the outer side of the limiting rod 30. One end of the limiting spring 28 is fixedly connected to the sliding cavity 27, and the other end is fixedly connected to the second slider 29. Since the contact ends of the limiting rod 30 and the spherical groove 24 are provided with granular protrusions, when the limiting rod 30 contacts the spherical groove 24, the spherical groove 24 is spherically...

[0023] The grip 4 is positioned between the support rod 21 and the first slider 3. The lower end of the first slider 3 slides into the T-groove 14, which is located at the upper end of the U-shaped plate 2. Spherical grooves 24 are provided on the opposite surfaces of the support rod 21 and the first slider 3. The surface of the spherical grooves 24 is provided with raised particles. Two spherical rods 23 are movably connected to the corresponding spherical grooves 24. The collection mechanism includes a net bag 22, which is fixedly connected to the lower end of the connecting ring 9. A guide hose 5 is fixedly connected to the lower end of the net bag 22, and the end of the guide hose 5 away from the net bag 22 is fixedly connected to the upper end of the storage box 1.

[0024] Working principle: During use, the U-shaped plate 2 is worn on the body via two shoulder straps 15. By pressing the T-shaped pressing rod 19, the extrusion block 25 moves inward along the connecting cavity 26. When the limiting rod 30 moves to the inclined position of the extrusion block 25, the second slider 29 moves downward under the elastic force of the limiting spring 28. At this time, the upper end of the limiting rod 30 is no longer in contact with the spherical groove 24, and the spherical rod 23 can rotate along the spherical groove 24. At this time, the support rod 21 can be operated to adjust the position and angle of the connecting ring 9. Adjust the pressure on the T-shaped pressing rod 19 and release it. At this time, under the elastic force of the connecting spring 20, the T-shaped pressing rod 19 will move outward and drive the squeezing block 25 to move synchronously. The movement of the squeezing block 25 will push the two limiting rods 30 to move upward. Since the contact ends of the limiting rods 30 and the spherical groove 24 are provided with granular protrusions, when the limiting rods 30 contact the spherical groove 24, the spherical rod 23 is limited in the spherical groove 24, so that the grip rod 4, the support rod 21 and the first slider 3 cannot move. When the avocado enters the inner side of the connecting ring 9, the sliding ring 13 is pulled down to move the two pull ropes 12. The movement of the pull ropes 12 causes the cutter 8 to move along the guide groove 10. The moving cutter 8 cuts the avocado and it falls into the net bag 22. The avocado in the net bag 22 will slide into the storage box 1 through the guide hose 5 for storage. When a certain amount of avocado is stored at the bottom of the storage box 1, the bottommost sliding rod 18 is pulled to move to the outside of the storage box 1. The sliding rod 17 can be rotated to limit the sliding rod 18. The movement of the sliding rod 18 causes the second baffle 32 to unfold. The unfolded second baffle 32 can separate the newly fallen avocado from the avocado at the bottom of the storage box 1. At the same time, the unfolded second baffle 32 can prevent the newly fallen avocado from falling onto the avocado surface at the bottom of the storage box 1. Once all the avocados at the corresponding height have been harvested, pressing the T-shaped pressing lever 19 again will prevent the limiting lever 30 from contacting the spherical groove 24, and the position of the connecting ring 9 can be adjusted by moving the support lever 21.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
