Description

Technical Field

[0001] The utility model relates to the technical field of pruning tools, in particular to a mulberry garden pruning tool. Background Art

[0002] A mulberry garden refers to a garden where mulberry trees are planted. Mulberry trees usually need to be pruned during their growth. The specific functions of mulberry pruning include: promoting nutritional growth, reducing pests and diseases, and increasing yield and quality. The method and timing of mulberry tree pruning are also critical: pruning from winter to early spring, pruning and trimming mulberry trees, can increase the yield of mulberry trees and the amount of mulberry leaves in the second year. Pruning is best done after the mulberry trees naturally shed their leaves until early spring. There are two types of felling: spring felling and summer felling. Spring felling can be done in spring to enhance the tree's vigor, but it will affect the leaf production during the spring silkworm period; summer felling can increase the spring leaf production, but it will have a certain impact on the tree's vigor. Pruning tools are usually used when pruning mulberry trees.

[0003] Currently, existing pruning tools generally consist of two handles and two blades. However, a significant limitation of these tools is the fixed shape of the handles. While short handles provide convenient operation when pruning small branches, they become a limitation when pruning larger branches, making it difficult to exert effective force, increasing workload and physical exertion. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a mulberry garden pruning tool.

[0005] The above technical purpose of the present utility model is achieved through the following technical solutions: a mulberry garden pruning tool, comprising two handles, the ends of the two handles are hinged by a hinge shaft, the ends of the two handles adjacent to the hinge shaft are respectively provided with a first scissor blade and a second scissor blade, a sleeve is slidably sleeved on the handle, a row of connecting columns and a row of connecting holes are provided on the side wall of the sleeve adjacent to the other sleeve, the connecting columns and the connecting holes on the two sleeves correspond to each other, and the handle is also provided with a fixing component for fixing the sleeve.

[0006] By adopting the above technical solution, a handle, an articulated shaft, a sleeve, and a fixing assembly are provided. When pruning thinner mulberry branches, there is no need to slide the sleeve, so that the pruning tool is smaller as a whole and easier to operate. When pruning thicker mulberry branches, the two sleeves are pressed and brought close to each other so that the connecting column is placed in the connecting hole of the other sleeve. The sleeves are then slid so that the two sleeves slide synchronously, and the sleeves are fixed by the fixing assembly so that the sleeves serve as an extension of the handle, which is easier for the staff to operate. Under the action of the lever effect, the first scissor blade and the second scissor blade have a greater force to cut the branches when pruning, which makes pruning thicker mulberry branches more labor-saving and reduces the workload and physical exertion.

[0007] Furthermore, the diameter of the connecting column is smaller than the diameter of the connecting hole, and the length of the connecting column is consistent with the length of the connecting hole.

[0008] By adopting the above technical solution, the diameter of the connecting post is set to be smaller than the diameter of the connecting hole, which facilitates the placement of the connecting post in the connecting hole. The length of the connecting post is set to be consistent with the length of the connecting hole, so that after the connecting post is placed in the connecting hole, the end of the connecting post is flush with the inner wall of the sleeve.

[0009] Furthermore, the fixing assembly includes a sliding hole opened at one end of the handle away from the hinge axis, and a receiving groove connected to the sliding hole is also opened in the handle, a sliding rod is slidingly arranged in the sliding hole, the end of the sliding rod is placed in the connecting hole to fix the sleeve, one end of the sliding rod is placed in the receiving groove and a baffle is provided, the baffle is slidably connected to the receiving groove, a compression spring is provided in the receiving groove, one end of the compression spring is connected to the groove wall of the receiving groove away from the sliding hole, and the other end is connected to the plate surface on the side of the baffle away from the sliding rod.

[0010] By adopting the above technical solution, a sliding hole, a receiving groove, a sliding rod, a baffle, and a compression spring are provided. When the position of the sleeve needs to be adjusted, the two sleeves are pressed and brought close to each other, so that the connecting column is placed in the connecting hole of the other sleeve, and the sliding rod is pressed into the sliding hole. At this time, the sleeve can slide on the corresponding handle; then the sleeve is slid backward to a suitable position, and the sleeve is released to separate the two sleeves; the connecting column leaves the connecting hole of the other sleeve, and the compression spring pushes the sliding rod out under the action of elastic force, so that the end of the sliding rod is placed in the connecting hole on the corresponding sleeve to fix the sleeve to the corresponding handle.

[0011] Furthermore, two groups of the fixing components are arranged at intervals on each handle.

[0012] By adopting the above technical solution, two groups of fixing components are arranged at intervals on each handle to ensure stable fixation of the sleeve.

[0013] Furthermore, the two sleeves are respectively provided with a connecting seat and a mounting seat at one end away from the hinge shaft, and a receiving hole is opened on the mounting seat adjacent to the connecting seat, and a block is provided in the receiving hole, and a first threaded rod is provided at the bottom of the block, and the length direction of the first threaded rod is perpendicular to the length direction of the sleeve, and the mounting seat is spirally engaged with the first threaded rod through the threaded hole, and the end of the first threaded rod away from the block passes through the mounting seat and is provided with a rotating cap.

[0014] By adopting the above technical solution, a connecting seat, a mounting seat, a receiving hole, a stop block, a first threaded rod, and a rotating cap are provided. The rotating cap is rotated to drive the first threaded rod to rotate, so that the stop block moves out of the receiving hole, so that when pruning, the end of the stop block contacts the connecting seat, and the two sleeves are not close to each other, avoiding the connecting column being placed in the connecting hole to push the sliding rod away when no adjustment is required; when the sleeve position needs to be adjusted, the rotating cap is rotated to drive the first threaded rod to rotate, so that the stop block is placed in the receiving hole.

[0015] Furthermore, a second threaded rod is provided at one end of the handle adjacent to the connecting seat away from the hinge axis, a through hole is provided on the connecting seat, a rotating shaft is rotatably provided on the mounting seat, a rotating plate is provided on the rotating shaft, a through hole is provided on the rotating plate, a nut is rotatably provided on the rotating plate at the through hole, and the nut is spirally engaged with the end of the second threaded rod passing through the through hole.

[0016] By adopting the above technical solution, a second threaded rod, a through hole, a rotating plate, and a nut are provided. When the pruning tool needs to be stored, the connecting seat and the mounting seat are first brought close together, and then the rotating plate is rotated so that the rotating plate contacts the connecting seat. Then, the sleeve is moved so that the second threaded rod passes through the through hole and the through hole and contacts the nut. The nut is rotated and screwed onto the second threaded rod, thereby fixing the rotating plate, the connecting seat, the mounting seat, and the handle. At this time, the pruning tool occupies less space and is easy to store.

[0017] Furthermore, a first magnet is provided on the mounting seat, and a second magnet is provided on the rotating plate, and the first magnet and the second magnet attract each other.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] like Figure 1-7 As shown, the embodiment of the present application discloses a mulberry orchard pruning tool, comprising a handle 10, a sleeve 20, and a fixing assembly 30. There are two handles 10, each hingedly connected by a hinge axis 11, allowing the two handles 10 to rotate relative to each other. A first shearing blade 12 and a second shearing blade 13 are respectively provided at the ends of the two handles 10 adjacent to the hinge axis 11. The adjacent sides of the first and second shearing blades 12, 13 are in contact. Rotating the handle 10 drives the first and second shearing blades 12, 13 to shear mulberry branches. A sleeve 20 is slidably mounted on the handle 10. A row of connecting posts 21 and a row of connecting holes 22 are provided on the sidewall of each sleeve 20 adjacent to the other sleeve 20. The connecting posts 21 and connecting holes 22 on the two sleeves 20 correspond to each other. The connecting posts 21 and connecting holes 22 are spaced apart along the length of the sleeve 20. The handle 10 is also provided with a fixing assembly 30 for securing the sleeve 20. When pruning thinner mulberry branches, there is no need to slide the sleeve 20, so that the pruning tool is smaller as a whole and easier to operate; when pruning thicker mulberry branches, press the two sleeves 20 and bring the two sleeves 20 close to each other so that the connecting column 21 is placed in the connecting hole 22 of the other sleeve 20, and then slide the sleeve 20 so that the two sleeves 20 slide synchronously, and then fix the sleeve 20 through the fixing assembly 30, so that the sleeve 20 serves as an extension of the handle 10, which is convenient for the staff to operate, and under the action of the lever effect, the first scissor blade 12 and the second scissor blade 13 have a greater force to cut the branches when pruning, which makes pruning thicker mulberry branches more labor-saving, reducing the workload and physical exertion.

[0032] Arc-shaped holes are provided on the inner walls of the two handles 10 near the hinge shaft 11, and an arc-shaped spring is provided between the two arc-shaped holes. The two ends of the arc-shaped spring are respectively connected to the bottom of the two arc-shaped holes. When the staff presses the sleeve 20 and the handle 10 to prune branches, the arc-shaped spring is compressed. When the sleeve 20 and the handle 10 are released, the arc-shaped spring pushes the handle 10 to reset under the action of elastic force, thereby resetting the first scissor blade 12 and the second scissor blade 13, which is convenient for the staff to operate.

[0033] Specifically, the fixing assembly 30 includes a sliding hole 31 defined at the end of the handle 10 away from the hinge axis 11. The core of the sliding hole 31 is aligned with the core of the connecting hole 22 of the corresponding sleeve 20. The handle 10 also includes a receiving slot 32 connected to the sliding hole 31. A sliding rod 33 is slidably disposed within the sliding hole 31. One end of the sliding rod 33 is positioned within the receiving slot 32 and is provided with a baffle 34. The baffle 34 is slidably connected to the receiving slot 32, allowing the sliding rod 33 and baffle 34 to slide synchronously. A compression spring 35 is disposed within the receiving slot 32. One end of the compression spring 35 is connected to the wall of the receiving slot 32 away from the sliding hole 31, and the other end is connected to the plate surface of the baffle 34 away from the sliding rod 33. In the initial state, the end of the sliding rod 33 is positioned within the connecting hole 22 at the outermost end of the corresponding sleeve 20, thereby fixing the handle 10 to the corresponding sleeve 20. When the position of the sleeve 20 needs to be adjusted, the two sleeves 20 are pressed together, so that the connecting post 21 is placed in the connecting hole 22 of the other sleeve 20, and the slide rod 33 is pressed into the slide hole 31. At this time, the sleeve 20 can slide on the corresponding handle 10; then the sleeve 20 is slid backward to the appropriate position, and the sleeve 20 is released, and the two sleeves 20 are separated; the connecting post 21 leaves the connecting hole 22 of the other sleeve 20, and the compression spring 35 pushes the slide rod 33 out under the elastic force, so that the end of the slide rod 33 is placed in the connecting hole 22 on the corresponding sleeve 20, fixing the sleeve 20 to the corresponding handle 10. The diameter of the connecting post 21 is smaller than the diameter of the connecting hole 22, which facilitates the placement of the connecting post 21 in the connecting hole 22. The length of the connecting post 21 is consistent with the length of the connecting hole 22, so that when the connecting post 21 is placed in the connecting hole 22, the end of the connecting post 21 is flush with the inner wall of the sleeve 20. When the sleeve 20 is slid, the sliding rod 33 does not interfere with the sliding of the sleeve 20. Two sets of fixing assemblies 30 are provided on each handle 10 at intervals to ensure stable fixing of the sleeve 20.

[0034] During setting, the two sleeves 20 are respectively provided with a connecting seat 40 and a mounting seat 50 at one end away from the hinge shaft 11. A receiving hole 51 is opened on the mounting seat 50 adjacent to the connecting seat 40. A stop block 52 is provided in the receiving hole 51. A first threaded rod 53 is provided at the bottom of the stop block 52. The length direction of the first threaded rod 53 is perpendicular to the length direction of the sleeve 20. The mounting seat 50 is spirally matched with the first threaded rod 53 through the threaded hole, so that rotating the first threaded rod 53 drives the stop block 52 to move. The end of the first threaded rod 53 away from the block 52 passes through the mounting seat 50 and is provided with a rotating cap 54. Rotating the rotating cap 54 drives the first threaded rod 53 to rotate, so that the block 52 moves out of the receiving hole 51, so that when pruning, the end of the block 52 contacts the connecting seat 40, thereby preventing the two sleeves 20 from being close to each other, avoiding the connection column 21 being placed in the connecting hole 22 and pushing the sliding rod 33 away when no adjustment is required; when the position of the sleeve 20 needs to be adjusted, rotating the rotating cap 54 drives the first threaded rod 53 to rotate, so that the block 52 is placed in the receiving hole 51.

[0035] In a specific configuration, a second threaded rod 60 is provided at one end of the handle 10 adjacent to the connecting seat 40 and away from the hinge shaft 11 , and the length of the second threaded rod 60 is consistent with the length direction of the handle 10 where it is located. The lock body 71 is fixed on the locking cam 72 of the locking cam 72, and the lock body 72 is fixed on the locking cam 72 to lock the cam 72. When the lock body 71 is unlocked, the lock body 71 is unlocked and the lock body 72 is unlocked. A first magnet 55 is provided on the mounting seat 50 and a second magnet 73 is provided on the rotating plate 71 . The first magnet 55 and the second magnet 73 attract each other so that in the non-accommodated state, the first magnet 55 and the second magnet 73 attract each other to limit the rotating plate 71 .

[0036] The principle of use of a mulberry garden pruning tool in this embodiment is as follows: when pruning thinner mulberry branches, there is no need to slide the sleeve 20, making the pruning tool smaller as a whole and easier to operate. When pruning thicker mulberry branches, press the two sleeves 20 together, so that the connecting column 21 is placed in the connecting hole 22 of the other sleeve 20, and press the slide bar 33 into the slide hole 31. At this time, the sleeve 20 can slide on the corresponding handle 10; then slide the sleeve 20 backward to the appropriate position, loosen the sleeve 20, and the two sleeves 20 are separated; the connecting column 21 leaves the connecting hole 22 of the other sleeve 20, and the compression spring 35 pushes the slide bar 33 out under the action of the elastic force, so that the end of the slide bar 33 is placed on the corresponding sleeve 20. The sleeve 20 is fixedly connected to the corresponding handle 10 in the connecting hole 22; then the rotating cap 54 is rotated to drive the first threaded rod 53 to rotate, so that the block 52 moves out of the accommodating hole 51, to avoid the connecting column 21 being placed in the connecting hole 22 and pushing the slide rod 33 away when no adjustment is needed; the sleeve 20 serves as an extension of the handle 10, which is convenient for the staff to operate, and under the action of the leverage effect, the first scissor blade 12 and the second scissor blade 13 have greater force to cut the branches during pruning, making pruning thicker mulberry branches more labor-saving, reducing the workload and physical exertion.
