Technical Field

[0001] The present application relates to the technical field of saws, and specifically to a handheld saw for forestry pruning. Background Art

[0002] Forestry is a discipline and industry that involves the management, protection, and utilization of forest resources. It not only focuses on the ecosystem and biodiversity of forests themselves but also involves the sustainable use of forest resources, including wood, wood fiber, medicine, food, eco-tourism, etc. When maintaining forestry trees, pruning work needs to be carried out on the branches of the trees to promote the growth and health of the trees. For this purpose, a handheld saw is required;

[0003] However, among the currently used handheld saw devices, the device usually contacts the branches with a blade. By the operator moving the device back and forth, the branches can be cut off. However, when the blade moves back and forth on the branches, the blade will shake significantly on the branches, and the blade may also get stuck on the branches. This will cause the blade to break easily, thus affecting the use effect of the device.

[0004] Therefore, it is necessary to provide a handheld saw for forestry pruning to solve the above problems. Utility Model Content

[0005] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a handheld saw for forestry pruning, which achieves the effect of edge clamping of the saw blade, thus solving the problem that the saw blade is prone to large-amplitude shaking.

[0006] The technical solution adopted by the present application to solve its technical problems is: a handheld saw for forestry pruning, including a cutting assembly, on which a clamping assembly is fixedly installed. The cutting assembly includes a main body, inside which a saw blade is arranged. The saw blade extends out of the outside of the main body, and the saw blade can contact the tree branches.

[0027] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe this application in detail with reference to the drawings and in combination with the embodiments.

[0028] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0029] As Figure 1 - Figure 3 shown, this application provides a hand-held saw for forestry pruning, including a cutting component 10 and a clamping component 20 fixedly installed on the cutting component 10. The cutting component 10 can contact the tree branches, so that the cutting component 10 can perform cutting work on the branches, and thus can maintain the trees. The clamping component 20 is used to perform a limiting and protecting work on the components on the cutting component 10, so as to improve the stability when the cutting component 10 is used

[0030] At the same time, the cutting component 10 includes a main body 11. One side of the main body 11 is fixedly installed with a handle 12. The handle 12 can be held by the staff, so that the staff can operate the whole device by holding the handle 12, and thus the operation is more comfortable and natural. This design helps to reduce the fatigue and discomfort of the staff and makes long-term work more feasible.

[0031] Meanwhile, an operation button 13 is fixedly installed on the handle 12. A motor 15 is fixedly installed inside the main body 11. The operation button 13 can turn the motor 15 on or off. A battery (not shown in the figure) is provided inside the main body 11, so that the main body 11 can supply power to the motor 15, and the battery can be replenished with power through an external power source, so that the battery can be used for a long time.

[0032] A fixed seat 14 is fixedly installed inside the main body 11. A gear a 16 is fixedly installed on the output shaft of the motor 15. A gear b 17 is meshed outside the gear a 16. Meanwhile, a hinge rod 18 is rotatably connected to the gear b 17. One end of the hinge rod 18 is hinged to a connecting rod 19. Meanwhile, a saw blade 110 is fixedly installed at one end of the connecting rod 19. The saw blade 110 can contact the branches of external trees. The fixed seat 14 can store and install the gear a 16, the gear b 17 and the hinge rod 18. Meanwhile, the connecting rod 19 can be limited in the fixed seat 14. After the motor 15 is turned on through the operation button 13, at this time, the gear a 16 will drive the gear b 17 to rotate, and then the hinge rod 18 will reciprocate the connecting rod 19 back and forth. At this time, the saw blade 110 can quickly reciprocate to cut the branches.

[0033] Meanwhile, the clamping assembly 20 includes a fixed block 22. A fixed rod 24 is fixedly installed on the fixed block 22. One end of the fixed rod 24 is threadedly connected to a bidirectional lead screw 25. Two groups of gears a 16 are threadedly connected to the outside of the bidirectional lead screw 25. Clamping plates 27 are fixedly installed at the opposite ends of the two groups of gears a 16. The clamping plates 27 are close to the edge of the saw blade 110. Thus, the two clamping plates 27 can block and limit the edge of the saw blade 110. When the saw blade 110 encounters a larger branch during operation, at this time, the saw blade 110 may get stuck on the branch, which may cause the saw blade 110 to bend. By blocking the two ends of the saw blade 110 with the clamping plates 27, the saw blade 110 can be protected, thus preventing the saw blade 110 from shaking significantly.

[0034] A turning handle 28 is fixedly installed at one end of the bidirectional lead screw 25. Meanwhile, a limiting groove 210 is formed on the fixed block 22. A limiting rod 29 is fixedly installed on the moving block 26 close to the limiting groove 210. The width of the limiting rod 29 is adapted to the internal width of the limiting groove 210. Thus, the operator can rotate the turning handle 28, so that the bidirectional lead screw 25 will rotate synchronously on the fixed rod 24. Then, the two moving blocks 26 will move away from or close to each other synchronously. Thus, the distance between the two clamping plates 27 can be adjusted, so that the clamping plates 27 can be adapted to saw blades 110 of different thicknesses. And the limiting rod 29 will move according to the movement of the moving block 26, and the limiting rod 29 will be at the limiting groove 210. Thus, the limiting rod 29 can limit the moving block 26.

[0035] A base 21 is fixedly installed at the bottom of the fixing block 22. The base 21 is located on the main body 11, and a bolt 23 is threadedly connected inside the base 21. At the same time, the fixing block 22 is fixedly installed on the base 21 through the bolt 23, and the bolt 23 can be removed, so that the fixing block 22 can be removed from the base 21, and then the whole clamping assembly 20 can be replaced or maintained later.

[0036] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
