Description

Technical Field

[0001] The present application relates to the technical field of landscaping, and specifically to a garden high-branch saw. Background Art

[0002] Within a certain geographical area, by applying engineering techniques and artistic means, through ingenious transformation of the terrain, such as techniques of building mountains, piling up stones, and managing water, and then by means of planting trees, flowers and plants, constructing buildings, and arranging garden paths, a beautiful natural environment and recreation area created with great care is called a garden. The scope of gardens is very extensive, including common types such as courtyards, residential gardens, small pleasure gardens, gardens, parks, botanical gardens, zoos, etc. With the continuous development of the garden discipline and people's emphasis on the natural environment, its scope has been further expanded, and it also covers forest parks, scenic spots, tourist areas of nature reserves or national parks, and resorts, etc. In all aspects of landscaping, a saw is an indispensable tool, which is widely used for pruning tree branches and leaves to keep the garden landscape clean and beautiful.

[0003] However, at present, most garden saws have a relatively obvious limitation in actual use, that is, the length cannot be conveniently adjusted. Due to this limitation, when using a garden saw, the staff can only prune the branches and leaves within the height range that they can reach. This means that for some branches and leaves growing at a higher position, if they exceed the maximum extension length of the garden saw, it is difficult for the staff to directly carry out effective pruning operations. In this case, not only does it affect the efficiency of the pruning work, but it may also lead to an incomplete garden landscape and fail to achieve the expected artistic effect. In addition, in order to meet the pruning requirements at different heights, the staff may need to carry a variety of garden saws with different length specifications, which undoubtedly increases the complexity and cost of the work. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] In order to solve the above technical problems, the present invention provides a garden high-branch saw to solve the problem that the length of the garden saw cannot be conveniently adjusted in actual use in the prior art.

[0006] (2) Technical Solutions

[0007] To achieve the above object, the present application is realized through the following technical solutions: A garden high-branch saw includes a box body, a handle, and a saw. The surface of the handle is wrapped with rubber. The lower surface of the box body is hinged with an extension mechanism for adjusting the height of the saw. The extension mechanism includes a support rod and a sliding rod. The sliding rod is threadedly connected inside the support rod. The handle is fixedly installed on the surface of the box body. Rotating the sliding rod can make the sliding rod slide inside the support rod to adjust the length of the whole device, and the staff holds the handle to carry the device.

[0008] Preferably, the support rod is hinged to the box body. Threads are provided on the outer surface, inner wall surface of the support rod and the surface of the sliding rod. The threads on the outer surfaces of the support rod and the sliding rod can play an anti-slip role for the hands of the staff.

[0009] Preferably, a disk for restricting the extension of the support rod is rotatably connected to one side of the box body. Limit holes are evenly provided on the surface of the disk. A limit rod is threadedly connected inside the limit hole. After adjusting the device to a suitable length, the staff rotates the limit rod to insert it into the limit holes on the surfaces of the disk and the box body to limit the rotation of the support rod.

[0010] Preferably, a cover plate for protecting the electric saw is slidably connected to the upper surface of the box body. The staff slides the cover plate to shield the electric saw to avoid hurting the staff and can also play a role in protecting the electric saw.

[0011] Preferably, a cutting mechanism is provided above the box body. The cutting mechanism includes a rotating plate which is rotatably connected to the box body. Rotating the rotating plate can store the electric saw in the box body to realize the expansion and contraction of the electric saw.

[0012] Preferably, a motor is fixedly installed on the surface of the rotating plate. A connecting plate is fixedly installed on the output shaft of the motor. The electric saw is fixedly installed on the surface of the connecting plate. Starting the motor, the rotation of the output shaft of the motor can drive the electric saw to flip and adjust the pruning angle.

[0013] Preferably, it further includes an extension mechanism for extending the length of the sliding rod. The extension mechanism includes an assemblable and disassemblable long rod member and a bracket member for supporting the long rod member. The extension mechanism is used to extend the length of the sliding rod so that the staff can stand on the ground to trim the garden branches. At the same time, in order to be able to store it after use to achieve the characteristic of convenient transportation, the extension mechanism includes an assemblable and disassemblable long rod member and a bracket member for supporting the long rod member. Among them, the bracket member is used to support the longer long rod member to provide a support point for it.

[0014] Preferably, the long rod member includes a plurality of cylindrical members and rod members. Thread grooves are formed on the inner walls of the cylindrical members. Threads are formed on the outer structures of the rod members for threaded connection with the cylindrical members so that the rod members can be assembled or disassembled end to end with the cylindrical members. The cylindrical members can be threadedly connected to the outer wall of the sliding rod.

[0015] Preferably, the support member includes a fixing unit detachably fixed to the outer wall of the cylindrical member. A universal ball head is fixed to the outer wall of the fixing unit, and a vertical rod with a threaded surface structure is fixedly arranged at one connecting rod end of the universal ball head. The vertical rod is threadedly connected with a sleeve rod with a sharpened end. The sleeve rod with a sharpened end is used to insert into the ground to provide a support point. For places where it is not suitable to insert into the ground, a tripod can be used to clamp outside the sleeve rod or the vertical rod to achieve the function of providing a support point. In this application, the vertical rod and the sleeve rod provide support, and combined with the universal function of the universal ball head, and a handle is welded and fixed on the last cylindrical member. Then, in practice, the handle can be held by hand, and combined with the function of the universal ball head, the swinging in all directions can be realized, and then the pruning of branches can be realized.

[0016] Preferably, the fixing unit includes two semi-circular fixing sleeves that are vertically aligned outside the cylindrical member. Fixing parts are constructed at the arc edges of the two semi-circular fixing sleeves. The two fixing parts located above and below are locked by bolts and nuts. During operation, the staff carries the device to a suitable position by holding the handle. Then, the support rod is unfolded by rotating the disc. According to the needs of the user, the sliding rod can be rotated to make the sliding rod slide inside the support rod to adjust the length of the whole device. After the device is adjusted to a suitable length, the staff rotates the limiting rod and inserts it into the limiting holes on the surfaces of the disc and the box body to limit the rotation of the support rod and ensure the stability of the device during use. Then, the electric saw is unfolded and the motor is started. The output shaft of the motor rotates to drive the electric saw to flip and adjust the pruning angle to meet the pruning requirements of branches in different directions. During the working process, the staff holds the sliding rod by hand, and the threads on the surface of the sliding rod play an anti-slip role on the hand, enhancing the safety and comfort of the operation. At the same time, in order to deal with taller garden trees, the sleeve rod with a sharpened end here is used to insert into the ground to provide a support point. For places where it is not suitable to insert into the ground, a tripod can be used to clamp outside the sleeve rod or the vertical rod to achieve the function of providing a support point. During specific operation, the vertical rod and the sleeve rod provide support, and combined with the universal function of the universal ball head, the staff can hold the handle by hand, and then combined with the function of the universal ball head, the swinging in all directions can be realized, so as to flexibly prune the branches. And, in order to achieve disassembly afterwards, the bolt and nut can be loosened first, so that the two semi-circular fixing sleeves can be detached from the cylindrical member. At the same time, the cylindrical member and the rod body are rotated to separate them, realizing the rapid disassembly of the whole lengthening mechanism, which is convenient for carrying and storing.

[0017] (III) Beneficial effects

[0018] This application provides a high-branch saw for gardens. The beneficial effects are as follows:

[0019] 1. By setting up a stretching mechanism, the length of the whole device can be adjusted, so that it is convenient for the electric saw to contact the branches and leaves at higher positions, solving the problem that the conventional garden saw is difficult to adjust the height and cannot prune the branches and leaves at different heights, realizing the function of improving the efficiency of garden greening pruning and pruning the branches and leaves at different heights.

[0020] 2. By driving the electric saw to rotate with a motor, pruning at different angles can be realized. Without manually rotating the whole device or moving the position, pruning at different angles can be achieved, improving the applicability of the device and meeting people's usage requirements.

[0021] 3. The lengthening mechanism is used to extend the length of the sliding rod, enabling personnel to stand on the ground to prune garden branches. At the same time, for the purpose of being able to be stored after use to achieve the characteristic of convenient transportation, the lengthening mechanism includes an assemblable and disassemblable long rod member and a bracket member for supporting the long rod member, wherein the bracket member is used to support the relatively long long rod member and provide a support point for it.

[0022] 4. The sleeve rod with a sharpened end is used to insert into the ground to provide a support point. For places where it is not suitable to insert into the ground, a tripod can be used to clamp outside the sleeve rod or the vertical rod to achieve the function of providing a support point. In this application, the vertical rod and the sleeve rod are used to provide support. Then, combined with the universal function of the universal ball head, and a handle is welded and fixed on the last cylindrical member. So in practice, the handle can be held, and then combined with the function of the universal ball head, swinging in all directions can be realized, and then pruning of the branches can be achieved.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0032] The present application will be further elaborated in detail below through the drawings and embodiments.

[0033] At present, most garden saws have a relatively obvious limitation in the actual use process, that is, they cannot conveniently adjust the length. Due to this limitation, when using a garden saw, the staff can only prune the branches and leaves within the height range that they can reach. This means that for some branches and leaves growing at a higher position, if they exceed the maximum extension length of the garden saw, it is difficult for the staff to directly carry out effective pruning operations. In this case, not only does it affect the efficiency of the pruning work, but it may also lead to an incomplete garden landscape and fail to achieve the expected artistic effect. In addition, in order to meet the pruning requirements at different heights, the staff may need to carry a variety of garden saws with different length specifications, which undoubtedly increases the complexity and cost of the work.

[0034] Refer to Figures 1 to 4, an embodiment of the present application provides a high-branch saw for gardens, including a box body 1, a handle 2, and a power saw 51. The surface of the handle 2 is wrapped with rubber. The lower surface of the box body 1 is hinged with an extension mechanism 3 for adjusting the height of the power saw 51. The extension mechanism 3 includes a support rod 31 and a sliding rod 32. The sliding rod 32 is threadedly connected inside the support rod 31. The handle 2 is fixedly installed on the surface of the box body 1. Rotating the sliding rod 32 can make the sliding rod 32 slide inside the support rod 31 to adjust the length of the entire device, and the staff can carry the device by hand holding the handle 2.

[0035] Referring to Figure 1 and Figure 2 , in one aspect of this embodiment, the support rod 31 is hinged to the box body 1. Threads are provided on the outer surface, inner wall surface of the support rod 31, and the surface of the sliding rod 32. The threads on the outer surfaces of the support rod 31 and the sliding rod 32 can play an anti-slip role for the hands of the staff.

[0036] Referring to Figure 1 and Figure 4 , in one aspect of this embodiment, a disc 33 for restricting the extension of the support rod 31 is rotatably connected to one side of the box body 1. Limiting holes 34 are evenly provided on the surface of the disc 33. A limiting rod 35 is threadedly connected inside the limiting holes 34. After adjusting the device to a suitable length, the staff rotates the limiting rod 35 to make it insert into the limiting holes 34 on the surfaces of the disc 33 and the box body 1 to play a role in limiting the rotation of the support rod 31.

[0037] Referring to Figure 1 , in one aspect of this embodiment, a cover plate 4 for protecting the power saw 51 is slidably connected to the upper surface of the box body 1. After the power saw 51 is received inside the box body 1, the staff slides the cover plate 4 to cover the power saw 51, avoiding injury to the staff, and at the same time can also play a role in protecting the power saw 51 and extending its service life.

[0038] Referring to Figure 3 , in one aspect of this embodiment, a cutting mechanism 5 is provided above the box body 1. The cutting mechanism 5 includes a rotating plate 52. The rotating plate 52 is rotatably connected to the box body 1. Rotating the rotating plate 52 can receive the power saw 51 inside the box body 1, realizing the expansion and contraction of the power saw 51, making the device more convenient during carrying and use.

[0039] Referring to Figure 3 , in one aspect of this embodiment, a motor 53 is fixedly installed on the surface of the rotating plate 52. A connecting plate 54 is fixedly installed on the output shaft of the motor 53. The power saw 51 is fixedly installed on the surface of the connecting plate 54. Starting the motor 53, the rotation of the output shaft of the motor 53 can drive the power saw 51 to flip and adjust the pruning angle.

[0040] In another embodiment of the present application, in order to correspond to relatively tall garden trees, this embodiment provides another solution:

[0041] Please refer to Figure 5 and Figure 6 , it further includes an extension mechanism 6. The extension mechanism 6 is used to extend the length of the sliding rod 32, so that personnel can stand on the ground to trim the garden tree branches. At the same time, in order to be able to be stored after use to achieve the characteristic of convenient transportation, the extension mechanism 6 includes an assemblable and disassemblable long rod member 61 and a support member 62 for supporting the long rod member 61. Among them, the support member 62 is used to support the longer long rod member 61 and provide a support point for it.

[0042] Specifically, the long rod member 61 includes a plurality of cylindrical members 611 and a rod body 612. The inner wall of the cylindrical member 611 is constructed with a thread groove 613, and the outer part of the rod body 612 is constructed with screw teeth that are threadedly connected to the cylindrical member 611, so as to form a state where the rod body 612 can be assembled or disassembled with the cylindrical member 611 at the head and tail. Please refer to Figure Five , by screwing the rod body 612 into the cylindrical member 611, connection and fixation can be achieved, and multiple rods can be connected infinitely. And in order to achieve assembly, the cylindrical member 611 can be threadedly connected to the outer wall of the sliding rod 32. In this way, the modification of garden trees that are not very tall and the trimming of taller trees after assembly can be realized, greatly improving the application range of the device.

[0043] More specifically, the support member 62 includes a fixing unit 621 that is detachably fixed to the outer wall of the cylindrical member 611. A universal ball head 622 is fixed to the outer wall of the fixing unit 621, and a vertical rod 623 with a threaded surface structure is fixedly arranged at one connecting rod end of the universal ball head 622. The outer part of the vertical rod 623 is threadedly connected with a sleeve rod 624 with a sharpened end. Here, the sleeve rod with a sharpened end is used to be inserted into the ground to provide a support point. For places where it is not suitable to be inserted into the ground, a tripod can be used to clamp outside the sleeve rod 624 or the vertical rod 623 to achieve the function of providing a support point. In the present application, the vertical rod 623 and the sleeve rod 624 provide support. Then, combined with the universal function of the universal ball head 622, and a handle is welded and fixed to the last cylindrical member 611. Then, in practice, the handle can be held, and then combined with the function of the universal ball head 622, swinging in all directions can be realized, and then the trimming of branches can be realized.

[0044] Please refer to Figure 6, a further description of the fixing unit 621 will be given here. First, the fixing unit 621 includes two semi-circular fixing sleeves 625 that are vertically aligned outside the cylindrical part 611. Fixing parts 626 are constructed at the arcuate edges of the two semi-circular fixing sleeves 625. The two fixing parts 626 located above and below are locked by bolts and nuts. The two semi-circular fixing sleeves 625 can be sleeved outside the cylindrical part 611 and then locked by bolts and nuts, which realizes the function of disassembly and fixing. This design enables easy disassembly when needed. Just loosen the bolts and nuts, and the two semi-circular fixing sleeves 625 can be conveniently removed from the cylindrical part 611. At the same time, rotate the cylindrical part 611 and the rod body 612 to separate them, achieving the quick disassembly of the entire lengthening mechanism 6, which is convenient for carrying and storage.

[0045] In this solution, all electrical equipment is powered by an external power supply, ensuring the power supply during the use of the device and avoiding the interruption of work caused by insufficient battery power.

[0046] Working principle: In actual operation, the staff holds the handle 2 to carry the device to a suitable position. Then, rotate the disc 33 to unfold the support rod 31. According to the user's needs, rotate the sliding rod 32, which can slide inside the support rod 31 to adjust the length of the entire device. After adjusting the device to a suitable length, the staff rotates the limiting rod 35 and inserts it into the limiting holes 34 on the surface of the disc 33 and the box body 1 to limit the rotation of the support rod 31 and ensure the stability of the device during use. Next, unfold the electric saw 51 and start the motor 53. The rotation of the output shaft of the motor 53 can drive the electric saw 51 to flip and adjust the trimming angle to meet the trimming requirements of branches in different directions. During the working process, the staff holds the sliding rod 32, and the threads on the surface of the sliding rod 32 play an anti-slip role for the hand, enhancing the safety and comfort of the operation.

[0047] At the same time, to deal with relatively tall garden trees, the sleeve rod 624 with a sharpened end here is used to insert into the ground to provide a support point. For places where it is not suitable to insert into the ground, a tripod can be used to clamp outside the sleeve rod 624 or the vertical rod 623 to achieve the function of providing a support point. During specific operation, with the support provided by the vertical rod 623 and the sleeve rod 624, combined with the universal function of the universal ball head 622, the staff can hold the handle, and then combined with the function of the universal ball head 622, achieve swinging in all directions, so as to flexibly trim the branches. And, to achieve disassembly afterwards, first loosen the bolts and nuts, so that the two semi-circular fixing sleeves 625 can be removed from the cylindrical part 611. At the same time, rotate the cylindrical part 611 and the rod body 612 to separate them, achieving the quick disassembly of the entire lengthening mechanism 6, which is convenient for carrying and storage.

[0048] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
