[0002] In landscaping and forestry pruning operations, traditional scissors often suffer from low cutting efficiency, awkward operation, poor adaptability, and limitations in the operating environment. Pruning trees in clusters or strips of trees close to buildings is particularly challenging with traditional scissors, often requiring the use of other tools such as saws or readjustment of the angle. Furthermore, if the trees are in clusters or strips close to walls, or if there are other obstructions, pruning becomes impossible, significantly reducing work efficiency.
[0003] When performing actual shearing work, the opening size of the shear head at one end of traditional scissors is equal to or smaller than the opening size of the handle. In this way, due to lack of operating space, the shear head cannot reach the position of the tree to be pruned, and the shearing work cannot be completed.
[0004] To address these issues, we proposed a multifunctional tree pruning shears, which aims to address the limitations of traditional tools in the tree pruning process.
[0005] The multifunctional tree trimming shears are carefully designed to achieve the goals of efficient cutting, labor-saving operation, convenient use and wide adaptability. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] like Figure 1-3The multifunctional tree trimming shears shown include a first scissors assembly 1, a second scissors assembly 2 and a ratchet bar 4. The first scissors assembly 1 is rotatably connected to the second scissors assembly 2. An elastic member 21 is provided on one side of the second scissors assembly 2. A clamping member 22 is hingedly connected to one end of the second scissors assembly 2. One end of the clamping member 22 is interconnected with one end of the elastic member 21. A one-way ratchet 43 is provided on one side of the ratchet bar 4. One end of the clamping member 22 is mutually engaged with the one-way ratchet 43 under the action of the elastic member 21. One side of the ratchet bar 4 is rotatably connected to a connecting rod 41. One end of the connecting rod 41 is rotatably connected to a second scissors head 42. The second scissors head 42 is rotatably connected to the first scissors assembly 1. One end of the first scissors assembly 1 is fixedly connected to the first scissors head 11 for engaging with the second scissors head 42 to cut trees.
[0025] One end of the first scissors assembly 1 and the second scissors assembly 2 are fixedly connected to a telescopic handle 3, which is used to increase the length of the first scissors assembly 1 and the second scissors assembly 2, making it easier to use. A limiting groove 31 is provided inside one end of the telescopic handle 3, and a telescopic rod 32 is slidably connected to the inner wall of the limiting groove 31. One end of the telescopic rod 32 is fixedly connected to the first scissors assembly 1 or the second scissors assembly 2. A fastening bolt 33 is threadedly sleeved on one side of the telescopic handle 3. When rotated and pushed, one end of the fastening bolt 33 squeezes one side of the telescopic rod 32 to fix the telescopic rod 32 to the telescopic handle 3. An anti-slip sleeve 34 is provided on the outside of one end of the telescopic handle 3. The outer wall of the anti-slip sleeve 34 is provided with raised points to increase friction and facilitate gripping. A clamping block 23 is fixedly connected to one side of the second scissors assembly 2, and the clamping block 23 and one end of the elastic member 21 are mutually sleeved. A hinged rod 221 is hinged to one end of the clamping member 22, and a one-way clamping block 222 is provided at the other end of the clamping member 22. The hinged rod 221 and one end of the elastic member 21 are mutually sleeved, and the one-way clamping block 222 is used for one-way clamping with the one-way ratchet 43.
[0026] The opening and closing angle between the first scissor head 11 and the second scissor head 42 is greater than the angle between the first scissor assembly 1 and the second scissor assembly 2, so that the first scissor head 11 and the second scissor head 42 can be engaged by repeatedly pulling the second scissor assembly 2 inward.
[0027] When in use, the staff holds the anti-slip cover 34 with both hands to force the second scissor head 42 and the first scissor head 11 to open to the maximum angle, and then places the scissor head on the outside of the branch to be cut. At this time, the first scissor assembly 1 is swung inward, and then the angle between the first scissor head 11 and the second scissor head 42 at the other end is reduced under the state that the clamping piece 22 is engaged with the one-way ratchet 43. Then, the first scissor assembly 1 is moved back and forth to the outside. At this time, the one-way clamping block 222 at one end of the clamping piece 22 will slide toward one end of the one-way ratchet 43, causing the one-way clamping block 222 to be engaged with the one-way ratchet 43 at the far end, and continue to rotate inward, thereby continuing to drive the second scissor head 42 and the first scissor head 11 to gradually reduce the angle between them, engage, and then complete the cutting of the branch;
[0028] After the engagement, the branch cutting is completed, and the user manually turns one end of the clamping member 22 in the direction of pressing the elastic member 21, driving the one-way clamping block 222 to disengage the one-way ratchet 43, and the opening and closing angle between the second scissor head 42 and the first scissor head 11 is increased. At this time, the clamping member 22 is released, and the elastic member 21 engages with the one-way ratchet 43, and the tree cutting operation can be carried out again.
[0029] During operation, this tool can cut large-sized objects because the opening angle of the scissor head can be greater than the opening angle of the scissor handle. At the same time, the handle can be rotated back and forth at a small angle multiple times to drive the scissor head to perform large-angle cutting. On the one hand, the cutting size does not need to be larger than that of the transmission scissors tool. On the other hand, the handle does not need to be opened at a larger angle, which is convenient for the staff to perform cutting operations and saves time and effort.
[0030] When the tool is in use and encounters an object that is difficult to cut, the fastening bolt 33 can be loosened by rotating it. At this time, the telescopic rod 32 inside the telescopic handle 3 can be pulled out, thereby increasing the overall length of the telescopic handle 3. At this time, it can be more labor-saving when cutting.
[0031] One end of the first scissors assembly 1 and the second scissors assembly 2 is fixedly connected to a telescopic handle 3 for increasing the length of the first scissors assembly 1 and the second scissors assembly 2, making it easier to use.
[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
