[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 and Figure 3 This utility model provides an embodiment of a forestry pruning tool, comprising two transmission rods 1. The transmission rods 1 are an important component of the entire forestry pruning tool, serving to connect different parts and transmitting force within the overall structure of the pruning tool. A rotating shaft 2 is fixedly connected to the bottom end of each transmission rod 1. A handle 3 is rotatably connected to the outside of the rotating shaft 2. When the pruning tool is being stored, the rotating shaft 2 allows the handle 3 to rotate upwards, thereby protecting the pruning section and allowing the entire pruning tool to be folded and stored. A storage protection assembly is fixedly connected to the bottom end of each handle 3. During use, the user grips the handle 3 and applies force to perform the pruning action. When not in use, the rotation of the handle 3 allows it to rotate to the top of the pruning tool to protect the pruning section. A replacement mechanism is fixedly connected to the top of the two transmission rods 1. An upper buffer pad is fixedly connected to the bottom side of the transmission rod 1, and a lower buffer pad is fixedly connected to the top side of the handle 3. The bottom side of the upper buffer pad is in contact with the top side of the lower buffer pad. The buffer pad reduces the pressure between the transmission rod 1 and the handle 3, thereby reducing wear.

[0035] Reference Figure 1 , Figure 5 and Figure 6The storage and protection component includes two protective covers 4. The top of the protective cover 4 is fixedly connected to the bottom of the handle 3. When the pruner is not in use, the protective cover 4 rotates to the top of the pruner under the rotation of the handle 3 to surround the pruning part, preventing the pruning part from causing accidental injury to people and protecting the pruning part from damage by external factors. An L-shaped plate 5 is fixedly connected to the bottom of the right protective cover 4, and a fixing block 7 is fixedly connected to the bottom of the left protective cover 4. A groove 8 is provided at the bottom of the fixing block 7, and a sliding plate 9 is slidably connected to the inner wall of the groove 8. The groove 8 is used for the sliding of the sliding plate 9 and provides guidance for the sliding of the sliding plate 9. A locking block 10 is fixedly connected to the bottom right of the sliding plate 9. The outer wall of the L-shaped plate 5 is in contact with the outer wall of the locking block 10. When the two protective covers 4 rotate towards the middle, the L-shaped plate 5 contacts and presses the locking block 10, causing the locking block 10 to move under the guidance of the sliding plate 9. A locking hole 6 is provided inside the L-shaped plate 5, and the outer side of the locking block 10 is engaged with the inner wall of the locking hole 6. A pressing block 11 is fixedly connected to the bottom left of the sliding plate 9. The function of the pressing block 11 is to allow the user to release the locking block 10 from the locking hole 6 by pressing, thereby opening the protective cover 4 so that the pruning tool can be used again. Two sliding pillars 12 are fixedly connected to the top of the sliding plate 9. The outer walls of the two sliding pillars 12 are slidably connected to the inner wall of the fixed block 7. A pressure plate 13 is fixedly connected to the outside of the two sliding pillars 12. A cavity is opened inside the fixed block 7. The outer wall of the pressure plate 13 is slidably connected to the inner wall of the cavity. Springs 14 are sleeved on the outside of the sliding pillars 12. The bottom sides of the two springs 14 are fixedly connected to the top side of the pressure plate 13. When the sliding plate 9 moves, the pressure plate 13 squeezes the springs 14 under the drive of the sliding pillars 12, changing the state of the springs 14. The top sides of the two springs 14 are fixedly connected to the bottom side of the left protective cover 4. Under the pressure of the L-shaped plate 5, they move into the fixed block 7. When the pressure plate 13 squeezes, the springs 14 are compressed and store energy. When the locking hole 6 on the L-shaped plate 5 reaches the position, when the pressure of the L-shaped plate 5 on the locking block 10 disappears, the springs 14 release energy and push the locking block 10 to engage with the locking hole 6, fixing the two protective covers 4.

[0036] Reference Figure 2 , Figure 3 and Figure 4The replacement structure includes a fixing plate 15, the bottom of which is fixedly connected to the top of the right transmission rod 1. Two connecting plates 16 are fixedly connected to the front of the fixing plate 15, and a blade 17 is fixedly connected to the left side of the two connecting plates 16. The fixing plate 15 provides a stable foundation for the entire replacement mechanism, ensuring the fixation and stability of the blade 17. A fixing rod 18 is fixedly connected inside the blade 17, and a rotating plate 19 is rotatably connected to the rear of the fixing rod 18. The bottom of the rotating plate 19 is fixedly connected to the top of the left transmission rod 1, and a blade 20 is detachably connected to the top of the rotating plate 19 by bolts. The outer wall of the blade 20 contacts the outer wall of the blade 17. The blade 17 is the mounting carrier for the blade 20. Through the cooperation of the fixing rod 18 and the rotating plate 19, the blade 20 can perform a cutting action. The rotating plate 19 can rotate around the fixed rod 18, driving the blade 20 to move. The bolt connection facilitates the quick replacement of the blade 20, improving the ease of use of the pruning shears. The bottom inner walls of both protective covers 4 are fixedly connected to storage boxes 21, which provide additional storage space for the pruning shears. They can hold disassembly and assembly tools and spare blades, making it convenient for users to replace or repair the blade 20 when needed. The inner wall of the storage box 21 is equipped with a drawer 22, which allows users to quickly open the storage box 21 to take out tools, further increasing the portability and usability of the pruning shears.

[0037] Working principle: When the pruner is not in use, rotating the two handles 3 upwards via the pivot 2 causes the protective covers 4 to rotate. The two protective covers 4 rotate to the top of the pruner, surrounding the pruning part. The rotating protective cover 4 on the right side causes the L-shaped plate 5 to contact the locking block 10 on the fixed block 7. Continuing to rotate the two protective covers 4 towards the center, the L-shaped plate 5 presses against the locking block 10, and with the guiding action of the sliding plate 9 on the groove 8, the locking block 10 moves into the fixed block 7. At the same time, the movement of the sliding plate 9, in conjunction with the connection of the sliding column 12, causes the pressure plate 13 to press against the spring 14. When the locking hole 6 on the L-shaped plate 5 moves to the position of the locking block 10, the locking block 10 loses the pressure of the L-shaped plate 5 and moves under the pressure generated by the compression of the spring 14, thus engaging with the locking hole 6. This completes the fixed connection of the two protective covers 4, protecting the pruning part of the pruner and preventing accidental injury from the pruning part. Furthermore, the pivot 2 allows the pruner to be folded and stored, increasing its convenience.

[0038] The blade 20 on the rotating plate 19 can be quickly replaced by bolts. The storage box 21 inside the protective cover 4 can be used to store disassembly tools and spare knives. The storage box 21 can be quickly opened by the drawer 22 to take out the tools, thus increasing the portability of the pruning tool.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
