Description
Technical Field
[0001] The utility model belongs to the technical field of multifunctional chicken bone shears, in particular to a multifunctional chicken bone shears with a spring gasket. Background Art
[0002] Chicken bone scissors are a commonly used kitchen utensil. Their basic structure includes a main knife and an auxiliary knife that are hinged together, and a switch structure for locking the main knife and the auxiliary knife open. Different blades are matched on the main knife and the auxiliary knife, so that the chicken bone scissors can have different uses.
[0003] The existing multifunctional chicken bone scissors have a first handle and a second handle connected by a rotating part, and a torsion spring is installed on the surface of the rotating part. The first handle and the second handle are pressed to bring the first handle and the second handle closer to each other for shearing. The torsion spring in the chicken bone scissors can provide a certain damping effect, so that the rotating part has balance and stability during rotation or movement. After pressing the first handle and the second handle closer to each other, the first handle and the second handle can be reset under the action of the torsion spring when the pressing hand is released. Although the first handle and the second handle can be reset after shearing by the torsion spring, after the two ends of the torsion spring arranged in the groove of the chicken bone scissors are fixed by being clamped with the slots in the first handle and the second handle, the torsion spring in the chicken bone scissors is easy to loosen when the chicken bone scissors are used for a long time for shearing. As a result, the first handle and the second handle cannot be quickly reset after shearing, thereby affecting the user experience. Utility Model Content
