[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a multi-functional forestry pruning saw, including a saw blade 1. One end of the saw blade 1 is provided with an adjustable handle structure 3, which can extend the actual operating length to better suit different user needs. The outer surface of the saw blade 1 is provided with a shearing structure 2, which can form a scissor-like structure to prune shorter branches. The shearing structure 2 includes a cutting arm 21. A round insertion hole 26 is opened on one side of the saw blade 1, and a round insertion rod 27 is fixedly connected to the bottom of the cutting arm 21. The round insert rod 27 is rotatably connected to the inner wall of the round insert hole 26. A round baffle 28 is fixedly connected to the bottom end of the round insert rod 27. The round insert rod 27 can rotate on the inner wall of the round insert hole 26, thereby forming a scissor-like structure with the cutting arm 21 and the saw blade 1. The round baffle 28 can limit the round insert rod 27 inside the round insert hole 26. The adjustable handle structure 3 includes a connecting block 31. One side of the connecting block 31 is fixedly connected to one side of the saw blade 1. A handle 32 is fixedly connected to the other side of the connecting block 31. The handle 32 can be used with other parts to facilitate hand operation.

[0027] Specifically, such as Figures 2-3As shown, a connecting rod 29 is fixedly connected to the bottom of the circular baffle 28, and an auxiliary circular plate 210 is fixedly connected to the bottom end of the connecting rod 29. A torsion spring 211 is sleeved on the outer surface of the connecting rod 29. The connecting rod 29 can cooperate with the auxiliary circular plate 210 so that the circular insert rod 27 can drive the torsion spring 211 to deform during rotation, and then cooperate with the cutting arm 21 to rotate and reset. The two ends of the torsion spring 211 are fixedly connected to the saw blade 1 and the auxiliary circular plate 210 respectively. A connecting plate 22 is fixedly connected to one side of the cutting arm 21. A first locking hole 23 is opened on the top of the connecting plate 22, and a second locking hole 24 is opened on the top of the saw blade 1. A locking rod 25 is engaged with the inner wall of the first locking hole 23 and the second locking hole 24. The locking rod 25 can cooperate with the first locking hole 23 and the second locking hole 24 to fix the connecting plate 22, and thus limit and fix the cutting arm 21.

[0028] Specifically, such as Figure 2 and Figure 4 As shown, a protective cover 33 is fitted onto the outer surface of the grip 32. The length of the protective cover 33 can be adjusted to accommodate different operators. A rectangular protrusion 34 is fixedly connected to the outer surface of the protective cover 33. The rectangular protrusion 34 can cooperate with the protective cover 33 to prevent slippage. A first insertion hole 35 is opened on one side of the grip 32, and a second insertion hole 36 is opened on one side of the protective cover 33. The same threaded rod 37 is inserted into the inner wall of the first insertion hole 35 and the second insertion hole 36. The threaded rod 37 can cooperate with the first insertion hole 35 and the second insertion hole 36 to limit and fix the grip 32 and the protective cover 33. A fixing nut 38 is threaded to one end of the threaded rod 37. The fixing nut 38 can limit and fix the threaded rod 37, so that the threaded rod 37 can fix the first insertion hole 35 and the second insertion hole 36.

[0029] The working principle of this utility model is as follows:

[0030] S1. When using the saw, when it is necessary to cut the tree, the saw blade 1 can be used directly for cutting, and the protective cover 33 can be held in hand to complete the cutting. When it is necessary to cut short branches, the locking rod 25 can be separated from the first locking hole 23 and the second locking hole 24.

[0031] S2. At this time, rotate the connecting plate 22 so that the cutting arm 21 and the saw blade 1 rotate relative to each other, so that short branches can be trimmed. At this time, the round insert rod 27 will rotate on the inner wall of the round insert hole 26, which can drive the torsion spring 211 to deform. When the connecting plate 22 is released, the connecting plate 22 can be reset under the action of the torsion spring 211, which makes it easier to operate.

[0032] S3. When it is necessary to adjust the grip length, pull out the handle 32 from the protective cover 33 to adjust the grip length between the protective cover 33 and the handle 32. Adjust it to align the first socket 35 and the second socket 36 according to actual needs. Then insert the threaded rod 37 into the first socket 35 and the second socket 36, and then fix the fixing nut 38 to the threaded rod 37 to fix the protective cover 33.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
