As the main tool for shearing sheep, the performance and function of wool shears directly affect the efficiency of shearing and the health of sheep.

[0003] Current market wool shears are mainly divided into two types: manual and automatic. Among them, the design of manual wool shears is quite similar to traditional scissors, such as the wool shears described in the Chinese utility model patent with the announcement number CN213616814U. The wool shears are mainly composed of key components such as blades, handles, and springs. In order to avoid the possibility of pinching the hand when the traditional cylindrical spring is bent, the patent innovatively uses a torsional spring design. However, this design still has some shortcomings:

[0004] Torsional spring exposure problem: Since the coil of the torsional spring is designed to protrude outward, most of its main body is exposed. Such a design not only affects the comfort of the operator's hand to some extent, making the torsional spring interfere with the hand feeling when it is stretched and retracted, but also increases the risk of damage to the torsional spring due to external environmental factors.

[0005] Shear head design problem: The shear head of the wool shears is designed in a sharp shape, which is extremely easy to accidentally prick the hand during operation. More critically, the sharp shear head may also cause pricking or scratching of the sheep's skin during shearing, thereby posing a potential threat to the health of the sheep.

[0006] Single function: Traditional wool shears usually only have a single shearing function, lacking other auxiliary functions such as wool combing and impurity removal, which limits their use efficiency and convenience to some extent.

[0007] Therefore, it is necessary to invent a multifunctional wool shears. UTILITY MODEL CONTENT

For the person skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] As shown in the accompanying Figure 1 to the accompanying Figure 4 drawings:

[0030] The multifunctional wool scissors provided by the present application comprise scissors blade 1, connecting piece 2, handle 3, torsion spring shaft 4, hidden torsion spring 5, buckle 6 and clamping groove 7, the scissors blade 1 is provided with two, the two scissors blade 1 is rotatably matched together through the connecting piece 2, each scissors blade 1 is fixedly connected with the corresponding handle 3 at one end, the two handles 3 are connected with the hidden torsion spring 5 through the torsion spring shaft 4 arranged on the handle 3, one end of one handle 3 is rotatably provided with a buckle 6, and one end of the other handle 3 is provided with a clamping groove 7 matched with the buckle 6.

[0031] Further, the two scissor blades 1 are polished on their opposite surfaces to have sharp edges to ensure the cutting efficiency when shearing the sheep. It is worth noting that the tip of each scissor blade 1 is not designed to be sharp, but rather has a smooth arc-shaped rounded end. This design not only improves the safety of operation, but also reduces the potential damage to the skin of the sheep. In addition, the arc-shaped rounded end of the scissor blade 1 has an outer edge without a blade, but a non-sharp chamfer is specially designed to further reduce the risk of accidental scratches.

[0032] Further, the end of each scissor blade 1 connected to the handle 3 is ingeniously provided with a clearance chamfer 8. This design not only provides a more stable connection for the scissor blade 1, but also provides enough space for the hidden torsion spring 5. The hidden torsion spring 5 is ingeniously located between the clearance chamfers 8 of the two scissor blades 1, which not only avoids the drawbacks of the traditional hidden torsion spring 5 exposed, but also ensures the normal activity of the hidden torsion spring 5 is not disturbed.

[0033] Further, the coil of the hidden torsion spring 5 is ingeniously located between the clearance chamfers 8 and near the end of the scissor blade 1 connected to the handle 3. This layout not only ensures the stability and durability of the hidden torsion spring 5, but also enables the scissor blade 1 to open and close smoothly during the shearing process. The two end ear spring heads of the hidden torsion spring 5 are respectively wound and fixed on the corresponding torsion spring shaft 4, and each handle 3 is fixedly installed with a torsion spring shaft 4, which provides a solid foundation for the fixation and activity of the torsion spring.

[0034] Further, the cross-section of the handle 3 is designed in a unique "n" shape, which not only makes the handle more ergonomic and improves the comfort of operation, but also provides enough space for the coil of the hidden torsion spring 5. The two oppositely arranged handles 3 can tightly fit together when closed, forming a compact whole, which not only facilitates carrying and storage, but also improves the convenience and flexibility of use.

[0035] Further, the handle 3 provided with the clamping groove 7 is ingeniously installed with a multifunctional auxiliary part 9. This design not only enriches the functions of the sheep shears, but also greatly improves its practicality. The multifunctional auxiliary part 9 specifically includes a damping shaft 91, a sheep scraper 92 and a sheep comb 93. Among them, the damping shaft 91 is stably fixed and installed on the handle 3 provided with the clamping groove 7, and is carefully located on one side of the clamping groove 7. Such layout not only ensures the stability of the structure, but also guarantees the convenience of operation. One end of the sheep scraper 92 and the sheep comb 93 is respectively connected with the damping shaft 91 to realize the damping rotation. This connection mode enables the sheep scraper 92 and the sheep comb 93 to rotate flexibly around the damping shaft 91, thereby meeting the needs of different operation angles. The design of the sheep scraper 92 facilitates the removal of impurities and dirt in the wool, while the sheep comb 93 is used for combing and arranging the wool, making the shearing process more efficient and neat.

[0036] Further, to further enhance the portability and practicality of the wool shears, the space of the handle 3 is ingeniously designed to accommodate the wool scraper 92 and the wool comb 93. This design not only saves additional storage space, but also makes the wool shears more compact and tidy in appearance when idle. The wool scraper 92 and the wool comb 93 can be folded inward and stored in the handle 3. Such storage method not only ensures the stability of the tools, but also avoids damage caused by collision or friction during carrying or storage. At the same time, the wool scraper 92 and the wool comb 93 are made of metal materials, which not only ensures the durability and strength of the tools, but also makes them maintain good use condition after long time use.

[0037] The working principle is as follows: in the initial state, the two scissors blades 1 are kept at a certain angle by the connecting piece 2, the hidden torsion spring 5 is in the pre-tightening state, and the two handles 3 are tightly connected through the cooperation of the buckle 6 and the card slot 7, forming a compact whole. When the wool needs to be sheared, the operator holds the handle 3 and applies outward force, making the buckle 6 disengage from the card slot 7, and at the same time, the hidden torsion spring 5 is stretched and stores elastic potential energy. As the handle 3 gradually opens, the scissors blades 1 also begin to gradually separate until the desired opening size is reached. Next, the operator aligns the sharp blade of the scissors blades 1 to the wool and applies inward force to cut the wool with the sharp blade. Because the blade head of the scissors blades 1 adopts a smooth arc fillet end and a non-sharp chamfer design, it can effectively avoid scratching the skin of the sheep. When the wool is successfully cut, the operator releases the handle, the hidden torsion spring 5 releases the stored elastic potential energy, and pushes the handle 3 and the scissors blades 1 back to the initial state quickly, completing a cutting action.

[0038] When installing the multifunctional wool shears, firstly, it is necessary to ensure that all components are intact and sorted according to the design drawing. Then, the two shear blades 1 are rotatably connected through the connecting piece 2 to ensure that they can be smoothly opened and closed. Next, the two handles 3 are respectively fixed at the corresponding end head positions of the shear blades 1, and it is ensured that the torsional spring shafts 4 are fixedly installed in the handles 3. Then, the spring ring of the hidden torsional spring 5 is cleverly placed between the clearance chamfers 8 of the two shear blades 1, and the two end ear spring heads thereof are respectively wound and fixed on the corresponding torsional spring shafts 4, so that the hidden torsional spring 5 can normally move and is not disturbed. Next, the buckle 6 is rotatably installed at the end head of one handle 3, and the clamping groove 7 cooperating with the buckle 6 is opened at the end head of the other handle 3, so that the buckle 6 and the clamping groove 7 can be tightly matched, and the two handles 3 can form a compact whole when closed. Finally, the multifunctional auxiliary part 9 is installed on the handle 3 provided with the clamping groove 7, including the damping shaft 91, the wool scraper 92 and the wool comb 93, so as to be stably fixed and damped rotation. After completing the installation of all components, the function test is carried out to ensure that the shears are smoothly opened and closed, and the hidden torsional spring 5 normally plays a role, and if necessary, adjustment and optimization are carried out to achieve the best performance state.

[0039] The technical scheme disclosed by the utility model, or the technical scheme designed by the person skilled in the art under the inspiration of the technical scheme of the utility model, similar technical schemes achieving the above technical effects fall within the protection scope of the utility model.
