A pair of constant-angle scissors comprising seven components: a scissors body (5a), a scissor body (6a), a scissor blade (5b), a scissor blade (6b), a connecting shaft (7a), a scissor handle (5c), and a scissor handle (6c). The scissor blade (5b) is provided on the upper part of the scissor body (5a). The scissor blade (6b) is provided on the upper part of the scissor body (6a). The scissor handle (5c) is provided at the lower part of the scissor body (5a). The scissor handle (6c) is provided at the lower part of the scissor body (6a). The constant-angle scissors is characterized in that: edges of the scissor blade (5b) and of the scissor blade (6b) are curve segments and are symmetric along the central axis line, and angles to the central axis at any scissor blade point of the scissor blade (5b) and of the scissor blade (6b) are approximately equal to a constant value. The constant-angle scissors not only can increase the average stress for all scissor blade points, but also can prevent the utilization rate of the scissor blades from being reduced. The scissors allows the angle to the central axis to be increased as much as possible with respect to the friction coefficient of a target object. The constant-angle scissors provided with a specific angle to the central axis allows for effortless and stable cutting of a specific target object, thus significantly optimizing the application performance of the constant-angle scissors. |
