Description

Technical Field

[0001] This utility model relates to the field of scissors technology, specifically a serrated garden pruning shears. Background Technology

[0002] Serrated garden pruning shears are a tool specifically designed for pruning plant branches. The blade is designed with a serrated structure, which makes the pruning shears more labor-saving and efficient when cutting thicker, harder or woody branches. They can cut easily without slipping. They are commonly used in gardening work, such as pruning branches of fruit trees, shrubs, flowers and other plants, to help shape the plant, promote growth or perform thinning management.

[0003] By adding serrations to the blades of the pruning shears, the shears gain a saw-like cutting ability when pruning thick branches, thus eliminating the need to carry an extra saw. This design not only improves the convenience of the pruning process, but also makes the pruning shears versatile for branches of different thicknesses, avoiding the need to frequently switch tools during the pruning process and greatly improving pruning efficiency.

[0004] Existing serrated garden pruning shears typically have the serrations located on the outside of the blade. While this design facilitates operation of the serrations, it also presents several problems. Due to the presence of the serrations, the blade length needs to be increased to better utilize their cutting function. However, increasing the blade length leads to increased force required during pruning. To reduce the force required during operation, the handle length also needs to be increased accordingly. As a result, the increased length of the blade and handle makes the overall size of the pruning shears larger, making them less flexible to carry and operate. This is especially true when used in confined spaces or dense vegetation, where the range of motion of the pruning shears is limited, increasing the difficulty of operation and affecting their practicality. Therefore, a serrated garden pruning shear is proposed to address the above problems. Utility Model Content

With the above settings, the saw tooth assembly 4 inside the auxiliary scissors 5 or the saw tooth assembly 4 inside the handle assembly 2 can be swapped as needed to serve as a backup and improve the continuity of operation.

[0033] As a further implementation of this solution, the blade groove 22 is connected to the anti-detachment groove 25, the blade groove 22 is aligned with the front and rear of the saw tooth body 42, the anti-detachment groove 25 passes through the front end of the handle body 21, the saw tooth body 42 protrudes out of the outer side of the anti-detachment groove 25, the inner side of the anti-detachment groove 25 is in contact with the outer side of the fixing strip 41, and the left side of the fixing strip 41 is in contact with the left side of the anti-detachment groove 25. Through the above settings, space is provided for the storage of the saw tooth body 42. When stored, it fits tightly with the handle, avoiding contact with external objects, which significantly improves the safety and convenience when carrying. At the same time, the direction of the fixing strip 41 can be changed as needed, so that the saw tooth body 42 is outside the handle body 21, which is convenient for cutting plants.

[0034] As a further implementation of this solution, the mounting groove 23 penetrates the right end of the handle body 21, the blocking block 32 is inserted into the inner side of the mounting groove 23, the front end of the blocking block 32 is flush with the front end of the handle body 21, the left side of the stop block 31 is attached to the right side of the handle body 21, the fixed toothed rack 41 is trapezoidal in shape, and the right side of the fixed toothed rack 41 is attached to the left side of the blocking block 32. Through the above settings, the blocking block 32 and the left side of the fixed toothed rack 41 are attached to limit the fixed toothed rack 41, improve the stability of the cutting operation, and prevent the fixed toothed rack 41 from detaching from the handle body 21.

[0035] As a further implementation of this solution, the pull rod 26 is shaped as two cylinders with different diameters.

The front end of the toothed plate 28 is provided with teeth, and the teeth of the toothed plate 28 are shaped as right-angled triangles. Through the above settings, the convenience of installing the fixing component 3 inside the handle assembly 2 can be improved, preventing the fixing component 3 from detaching from the handle assembly 2 after installation. At the same time, the fixing component 3 can be removed, thereby removing the toothed rack 41, which improves the practicality and operational flexibility of the tool.

[0036] Workflow: When pruning plants, initially the fixed toothed bar 41 is inside the anti-detachment groove 25, the saw tooth body 42 is inside the blade groove 22, and the saw tooth body 42 of the auxiliary shears 5 is also inside the auxiliary shears 5. One side of the fixed toothed bar 41 is flush with the front end of the handle body 21. Hold the handle body 21 and the handle body 21 on the auxiliary shears 5 with both hands, and drive the blade 1 or the blade 1 of the auxiliary shears 5 to rotate by operating the handle body 21 to achieve the effect of pruning plants. The length of the handle body 21 is greater than the length of the blade 1. The device sets the saw teeth on the handle, which can greatly reduce the labor intensity of the operator and improve the convenience of use. At the same time, the device reduces the space occupied by the blade 1, improves the convenience and safety of carrying, and is suitable for use in narrow or dense vegetation.

[0037] When cutting the plant, pulling the lever 26 moves the toothed plate 28 backward. The toothed plate 28 presses against the spring telescopic rod 27. Under the elastic force of the spring telescopic rod 27, the toothed plate 28 can be kept moving forward, improving the stability of the engagement between the toothed plate 28 and the one-way tooth 33. The shape of the one-way tooth 33 can prevent the toothed plate 28 from disengaging from the engaged one-way tooth 33. When the toothed plate 28 moves away from the one-way tooth 33, the stop block 31 can be pulled away. The moving blocking block 32 and the one-way tooth 33 are pulled out from the mounting groove 23, and then the fixed tooth 41 is pulled out from the anti-detachment groove 25. Then, with the saw tooth body 42 facing forward, the fixed tooth 41 is slid into the anti-detachment groove 25. The shape and structure of the anti-detachment groove 25 are designed to prevent the fixed tooth 41 from detaching from the anti-detachment groove 25 even after the fixed tooth 41 is reversed. When the left side of the fixed tooth 41 is in contact with the left side of the anti-detachment groove 25, the saw tooth body 42 is in the handle position. With the front end of the main body 21 on the outside, the blocking block 32 is inserted into the mounting groove 23. At this time, the one-way teeth 33 press against the toothed plate 28. After being pressed, the toothed plate 28 will move backward. Under the elastic force of the spring telescopic rod 27, the toothed plate 28 and the one-way teeth 33 remain engaged. When the left side of the blocking block 32 is in contact with the left side of the mounting groove 23, the left side of the blocking block 32 is in contact with the right side of the fixed toothed strip 41, completing the installation. In this way, by holding the blocking block 31 and the auxiliary scissors 5, the plant can be cut by the saw body 42. This working principle allows the saw body 42 to be stored inside the blade groove 22 when not in use, avoiding the danger caused by the saw body 42 coming into contact with external objects during carrying. It is convenient to operate the handle. At the same time, the saw component 4 inside the auxiliary scissors 5 or the saw component 4 inside the handle assembly 2 can be used at any time according to the cutting needs, improving the convenience and practicality of use.

[0038] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
