[0020] 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.

[0021] Please see Figures 1-8 The illustration shows a garden saw for pruning, including a housing 1, a telescopic handle 2, and a saw blade 3. The telescopic handle 2 is fixedly installed on one side of the housing 1. The saw blade 3 is located on the side of the housing 1 away from the telescopic handle 2. There are two sets of saw blades 3. The adjacent sides of the two sets of saw blades 3 are inclined and partially overlap. A moving mechanism is provided between the two sets of saw blades 3. A cavity 4 is opened inside the housing 1. Two sets of clamping plates 5 are provided above the saw blade 3. The adjacent sides of the two sets of clamping plates 5 are arc-shaped. An adjustment mechanism is provided between the two sets of clamping plates 5. A rotatable cleaning component 30 is provided above the saw blade 3. The cleaning component 30 is in contact with the surface of the saw blade 3.

[0022] Specifically, by using the telescopic handle 2, the outer casing 1 is moved closer to the branch to be pruned, so that the branch can be positioned between the two sets of clamping plates 5. The adjustment mechanism drives the two sets of clamping plates 5 to move closer together, clamping the branch. This method can clamp branches of different thicknesses, making it more widely applicable. The moving mechanism drives the two sets of saw blades 3 to move closer together. When the saw blades 3 move closer together, they can prune the branch. It should be noted that the two sets of saw blades 3 are not on the same horizontal line. As the two sets of saw blades 3 move closer together, they partially overlap. By setting two sets of saw blades 3, not only can the pruning efficiency be improved, but the branch can also be pruned simultaneously from both sides. This can prevent the branch from tilting to one side during pruning and can also prevent the branch from not being completely cut. With the cooperation of the two sets of clamping plates 5, the stability of the saw blades 3 can be ensured when pruning the branch. After pruning, the branch can also be pulled, so that branches at high positions can be pulled directly to the ground after pruning. This helps reduce the workload of workers and improves the safety of pruning.

[0023] The moving mechanism includes a guide groove 18 and a guide block 19. The guide groove 18 is opened inside the housing 1 on the side close to the saw blade 3. The guide block 19 is slidably installed inside the guide groove 18. There are two sets of guide blocks 19. A drive component is provided between the guide block 19 and the saw blade 3. A power structure is provided between the two sets of guide blocks 19.

[0024] The power structure includes a rod 20, which rotates through two sets of guide blocks 19. The outer surface of the rod 20 is provided with a threaded groove 21, which is threadedly connected to the guide blocks 19. A motor 22 is fixedly installed at one end of the rod 20, and the motor 22 is fixedly connected to the outer casing 1.

[0025] Specifically, the motor 22 is connected to an external power source. The motor 22 drives the rod 20 to rotate. Since the threaded groove 21 and the guide block 19 are threadedly connected, the rod 20 can drive the two sets of guide blocks 19 to move closer or further apart inside the guide groove 18 when it rotates. When the two sets of guide blocks 19 move closer to each other, they drive the saw blade 3 to move synchronously.

[0026] The drive assembly includes a fixed plate 29, which slides through the guide block 19. The fixed plate 29 and the saw blade 3 are fixedly connected. An electric push rod 25 is fixedly installed inside the cavity 4. The output end of the electric push rod 25 is connected to the fixed plate 29 through a sliding structure.

[0027] The sliding structure includes a mounting plate 26, which is slidably installed inside the cavity 4. The mounting plate 26 is fixedly connected to the output end of the electric push rod 25. A track 27 is fixedly installed on the side of the mounting plate 26 away from the electric push rod 25. A mounting seat 28 is slidably installed on the outer surface of the track 27. The mounting seat 28 is fixedly connected to the end of the fixing plate 29 away from the saw blade 3.

[0028] The electric push rod 25 is connected to an external power source. The output end of the electric push rod 25 drives the mounting plate 26 to move inside the cavity 4. Since the fixed plate 29 is connected to the mounting plate 26 through the mounting block and the track 27, the mounting plate 26 can drive the saw blade 3 to move through the fixed plate 29 when it moves. At this time, the saw blade 3 moves towards or away from the outer shell 1. At the same time, the guide block 19 can also drive the mounting seat 28 to move on the outer surface of the track 27 through the fixed plate 29, so that the two sets of saw blades 3 can move closer or further away from each other.

[0029] Furthermore, when motor 22 is not working and electric push rod 25 is working, the position of one set of saw blades 3 can be adjusted so that the two sets of saw blades 3 face the same direction, thereby pruning the small branches and leaves on the outer surface of the tree. When motor 22 is working and electric push rod 25 is not working, the two sets of saw blades 3 move closer to each other and can cut the branches. Those skilled in the art can switch the working state of the device according to actual needs. The device has at least three working states and has a wide range of applications.

[0030] The adjustment mechanism includes a slide 6 and a slider 7. The slide 6 is opened inside the housing 1 on the side near the saw blade 3. The slide 6 is located above the guide groove 18. The slider 7 is slidably installed inside the slide 6. The slider 7 and the clamping plate 5 are fixedly connected. A pushing component is provided between the two sets of sliders 7. A limit component is provided on the outer surface of the slider 7.

[0031] The pushing component includes a push plate 9, which is slidably installed inside the cavity 4. A trigger structure is provided between the push plate 9 and the outer shell 1. Plates 12 are rotatably installed on both sides of the push plate 9. The ends of the two sets of plates 12 away from the push plate 9 are respectively rotatably connected to two sets of sliders 7.

[0032] The triggering structure includes a slide rod 10, which is fixedly installed on the side of the push plate 9 near the saw blade 3. The end of the slide rod 10 away from the push plate 9 passes through the outer casing 1 and extends to the outside of the outer casing 1. An adjusting plate 8 is fixedly installed on the end of the slide rod 10 away from the push plate 9. A first spring 11 is movably sleeved on the outer surface of the slide rod 10. The first spring 11 and the adjusting plate 8 are fixedly connected.

[0033] As the outer casing 1 moves toward the branch, the branch is positioned between the two sets of clamping plates 5. The adjusting plate 8 first contacts the branch and stops moving. The outer casing 1 continues to move toward the branch. At this time, the adjusting plate 8 drives the push plate 9 to move inside the cavity 4 via the slide rod 10. The first spring 11 deforms under force. When the push plate 9 moves, it can drive the plate 12 to rotate. The plate 12 pulls the slider 7 to move inside the slide groove 6, thereby providing power for the movement of the clamping plates 5. This allows the two sets of clamping plates 5 to move closer to each other to clamp the branch. Moreover, in this way, the cross-section of the saw blade 3 is minimized when pruning the branch, which can reduce the damage to the tree during pruning.

[0034] The limiting assembly includes a support plate 15, which is slidably installed inside the cavity 4. A support rod 16 slides through the inside of the support plate 15 and is fixedly connected to the outer shell 1. A second spring 17 is movably sleeved on the outer surface of the support rod 16 and is fixedly connected to the support plate 15. Several sets of limiting blocks 14 are fixedly installed on the side of the support rod 16 near the slider 7. A limiting hole 13 is opened on the side of the slider 7 near the limiting block 14. The limiting hole 13 and the limiting block 14 are inserted and fitted. A first protrusion 23 is fixedly installed on both sides of the lower part of the support plate 15. A second protrusion 24 is fixedly installed on the upper part of the guide block 19. The end faces of the first protrusion 23 and the second protrusion 24 on adjacent sides are inclined and are in contact with each other.

[0035] Initially, protrusion 23 and protrusion 24 are in contact, and spring 17 is compressed. Limiting block 14 is not inserted into limiting hole 13. When the two sets of saw blades 3 approach each other, guide block 19 causes protrusion 24 to separate from protrusion 23. Under the action of spring 17, spring 17 pushes support plate 15 to move towards guide block 19 on the outer surface of support rod 16. It should be noted that at this time, the two clamping plates 5 have already clamped the branch. When support plate 15 moves... When the limiting block 14 is inserted into the limiting hole 13, the movement of the clamping plate 5 is restricted, making the clamping plate 5 hold the branch more firmly. After pruning, the pruned branch can also be pulled down through the clamping plate 5. When the branch falls to the ground, the two sets of saw blades 3 move away from each other, and the second protrusion 24 can move the first protrusion 23, so that the support plate 15 drives the limiting block 14 to move out of the limiting hole 13. Under the action of the first spring 11, the two sets of clamping plates 5 can be reset, which is convenient for the next pruning of the branch.

[0036] The cleaning component 30 is rotatably connected to the outer shell 1 via the shaft 35. A water pipe 34 is installed on the side of the shaft 35 away from the cleaning component 30. The cleaning component 30, the water pipe 34 and the shaft 35 are interconnected. A storage box 33 is fixedly installed on the end of the water pipe 34 away from the shaft 35. The storage box 33 is installed inside the cavity 4. A gear 31 is fixedly sleeved on the outer surface of the shaft 35. A rack 32 is fixedly installed above the guide block 19. The gear 31 and the rack 32 mesh with each other.

[0037] With the cooperation of water pipe 34 and shaft 35, the cutting fluid stored inside storage box 33 can enter the interior of cleaning component 30. When slider 7 drives saw blade 3 to move below cleaning component 30, due to the meshing of gear 31 and rack 32, rack 32 can drive shaft 35 to rotate through gear 31, thereby driving cleaning component 30 to rotate. This allows cutting fluid to be applied to the surface of saw blade 3, which helps to cool saw blade 3 and prevent saw blade 3 from deforming or wearing due to overheating. Moreover, cutting fluid can form a protective film between saw blade 3 and branches, reducing friction and thus reducing resistance during pruning, which helps to extend the service life of saw blade 3. It can also clean the surface of saw blade 3 and prevent waste from sticking to the surface of saw blade 3, affecting the pruning effect.

[0038] Working principle: By using the telescopic handle 2, the outer shell 1 is moved closer to the branch that needs to be pruned, so that the branch can be positioned between the two sets of clamping plates 5. The adjusting plate 8 first contacts the branch and stops moving. The outer shell 1 continues to move towards the branch. At this time, the adjusting plate 8 drives the push plate 9 to move inside the cavity 4 through the slide rod 10. The first spring 11 is deformed by the force. When the push plate 9 moves, it can drive the plate 12 to rotate. The plate 12 pulls the slider 7 to move inside the slide groove 6, thereby providing power for the movement of the clamping plates 5, so that the two sets of clamping plates 5 can move closer to each other to clamp the branch.

[0039] Connect the motor 22 to an external power source. The motor 22 drives the rod 20 to rotate. Since the threaded groove 21 and the guide block 19 are threadedly connected, the rod 20 can drive the two sets of guide blocks 19 to move closer or further apart inside the guide groove 18 when it rotates. When the two sets of guide blocks 19 move closer to each other, they drive the saw blade 3 to move synchronously.

[0040] The electric push rod 25 is connected to an external power source. The output end of the electric push rod 25 drives the mounting plate 26 to move inside the cavity 4. Since the fixed plate 29 is connected to the mounting plate 26 through the mounting block and the track 27, the mounting plate 26 can drive the saw blade 3 to move through the fixed plate 29 when it moves. At this time, the saw blade 3 moves towards or away from the outer shell 1. At the same time, the guide block 19 can also drive the mounting seat 28 to move on the outer surface of the track 27 through the fixed plate 29, so that the two sets of saw blades 3 can move closer or further away from each other.

[0041] Furthermore, when motor 22 is not working and electric push rod 25 is working, the position of one set of saw blades 3 can be adjusted so that the two sets of saw blades 3 face the same direction, thereby pruning the small branches and leaves on the outer surface of the tree. When motor 22 is working and electric push rod 25 is not working, the two sets of saw blades 3 move closer to each other and can cut the branches. Those skilled in the art can switch the working state of the device according to actual needs. The device has at least three working states.

[0042] Initially, protrusion 23 and protrusion 24 are in contact, and spring 17 is compressed. Limiting block 14 is not inserted into limiting hole 13. When the two sets of saw blades 3 approach each other, guide block 19 causes protrusion 24 to separate from protrusion 23. Under the action of spring 17, spring 17 pushes support plate 15 to move towards guide block 19 on the outer surface of support rod 16. It should be noted that at this time, the two clamping plates 5 have already clamped the branch. When support plate 15 moves... When the limiting block 14 is inserted into the limiting hole 13, the movement of the clamping plate 5 is restricted, making the clamping plate 5 hold the branch more firmly. After pruning, the pruned branch can also be pulled down through the clamping plate 5. When the branch falls to the ground, the two sets of saw blades 3 move away from each other, and the second protrusion 24 can move the first protrusion 23, so that the support plate 15 drives the limiting block 14 to move out of the limiting hole 13. Under the action of the first spring 11, the two sets of clamping plates 5 can be reset, which is convenient for the next pruning of the branch.

[0043] With the cooperation of water pipe 34 and shaft 35, the cutting fluid stored inside storage box 33 can enter the interior of cleaning component 30. When slider 7 drives saw blade 3 to move below cleaning component 30, due to the meshing of gear 31 and rack 32, rack 32 can drive shaft 35 to rotate through gear 31, thereby driving cleaning component 30 to rotate, so that cutting fluid can be applied to the surface of saw blade 3.
