Fiber optic scissors with double edge

This creation provides a fiber-optic scissors with a double-edged edge that is related to the structure of the scissors.

With the vigorous development of the optical communication industry, the demand for optical fibers and their components is increasing day by day. However, in the construction of optical fiber lines, the optical fiber wires must be cut, and the general optical fiber wires mainly include an outer core of optical fibers. Providing a plurality of fine lines, and the thin wires are covered with a coating layer, and the thin wires and the coating layer are used to protect the optical fiber core and provide bendability; and generally used for cutting the optical fiber wire The method is that the scissors can be cut by the general scissors. However, due to the hard core of the optical fiber, the general scissors has a difficult problem in the cutting operation, and even the optical fiber core is hard to cause damage to the scissors blade; therefore, the user usually That will carry two scissors, one cut fiber core, one sharply cut the outer core of the fiber core, and must be replaced with different scissors at different time, which is inconvenient to use; another fiber scissors As shown in FIG. 1 , the optical fiber scissors 10 are mainly composed of two shanks 11 pivotally connected, and each shank 11 has a first blade portion 111 and a second blade portion 112 respectively. 111 is the same as the general scissors blade, and the second blade portion 112 is formed by the inclined surface of the shank 11 to form a thick and thin curved edge, and the second of the fiber scissors 10 is the second of the shank 11 The blade portion 112 improves the shear force through the tangential interleaving of the curved cutting edge and can be applied to the fiber core and the covering of the fiber strand The cutting edge of the curved cutting edge makes the soft and thin wire easy to slip during the cutting action, so the first blade portion 111 of the fiber scissors 10 can be used for cutting the thin wire, thereby the fiber scissors The cutting of the optical fiber wire A by different blade portions can surely complete the cutting action and reduce the possibility of blade damage; however, although the fiber scissors 10 can reduce the wear of the blade compared with the general scissors, the second of the fiber scissors 10 The blade portion 112 is formed by being inclined and concavely formed by the surface of the shank 11. As shown in Fig. 2, the thickness of the second blade portion 112 of the fiber-optic scissors 10 is an acute angle from the thickness of the tapered surface to the angle of the surface. The second blade portion 112 of the fiber-optic scissors 10 is the weakest part of the thickness of the entire blade, which in turn causes the structural strength of the second blade portion 112 to be insufficient, and is thinned due to the hardness of the fiber core. The sharp edge of the cutting edge, and easy to wear, the lack of short life; in view of this, the author conceived and further research, and finally created a fiber-optic scissors with double edge.
