When in use, the optical fiber is first clamped with the optical fiber clamp 3, and then placed on the base 1, and the pressure cover 2 is covered to cut the optical fiber. After the cutting is completed, the pressure cover 2 is opened first, and then the optical fiber clamp 3 is removed, and then the optical fiber is removed. This operation is relatively cumbersome and affects the operator's experience in long-term use. Now a cutting knife with simple operation is needed for use. Utility Model Content

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0023] As Figure 1 , Figure 2 and Figure 3 shown, the present utility model relates to a pressing plate linkage type optical fiber cutter, which includes a base 1. A pressing cover 2 is hinged on the base 1. Both the base 1 and the pressing cover 2 are prior arts. A cutter assembly for cutting optical fibers is installed on the base 1 and the pressing cover 2. The cutter assembly is also a prior art. Since the innovation point of this application is not in the cutter assembly, no detailed description is made for the cutter assembly in this solution.

[0024] A square groove 2.1 is provided on one side of the base 1. A screw hole 2.2 is provided in the groove 2.1. A fixture base 3.1 is placed in the groove 2.1. The fixture base 3.1 is fixedly connected to the base 1 by screws.

[0025] Combined with Figure 4 and Figure 5 shown, a cover plate 3.2 is hinged on the fixture base 3.1. Specifically, the cover plate 3.2 includes a square plate. A pressure pad 6 is pasted on the inner side of the square plate. The pressure pad 6 is used to press the optical fiber. A rocker 3.3 is provided at one end of the square plate, and a joint seat 3.4 is provided at the other end. When in use, the rocker 3.3 is convenient for manually opening the cover plate 3.2. The joint seat 3.4 is composed of two folding plates. A through hole is provided on each folding plate. During installation, the joint seat 3.4 is arranged in the hinge groove 3.5 and connected by a hinge shaft 5. The hinge shaft 5 is connected in the through hole of the folding plate. A hook plate 4 is arranged on one side of the square plate. The square plate and the hook plate 4 are of an integral structure. The hook plate 4 is an L-shaped plate, and the upper side plate of the L-shaped plate is an arc plate 4.1.

[0026] Combined with Figure 6 and Figure 7As shown in the figure, a pressure rod 7 is connected to the rear side of the gland 2, and a linkage rod 8 is connected to the front side. The pressure rod 7 and the linkage rod 8 are connected to the same side as the cover plate 3.2, and the pressure rod 7 and the linkage rod 8 are correspondingly arranged on both sides of the hook plate 4. The pressure rod 7, the linkage rod 8 and the hook plate 4 are in linkage cooperation. The specific connection method is that the linkage rod 8 is arranged inside the arc groove of the arc plate 4.1. Under the action of the arc plate 4.1, when the gland 2 is opened, the linkage rod 8 drives the arc plate 4.1 to open together. The pressure rod 7 is arranged outside the arc plate 4.1. When the gland 2 is closed, the pressure rod 7 drives the arc plate 4.1 to close together.

[0027] Combined with Figure 8 As shown in the figure, the pressure rod 7 includes a mounting plate 7.1. The mounting plate 7.1 is a square plate. Mounting holes 7.3 are provided on the mounting plate 7.1. A pressing plate 7.2 is provided on one side of the mounting plate 7.1. The pressing plate 7.2 is a rectangular plate. The mounting plate 7.1 and the pressing plate 7.2 are inclined, and the pressing plate 7.2 is correspondingly arranged with the hook plate 4.

[0028] The specific connection method of the pressure rod 7 and the linkage rod 8 is that an installation groove 9 is provided at the bottom of the rear side of the gland 2. A screw hole is provided in the installation groove 9. When the pressure rod 7 is connected, the mounting plate 7.1 is placed in the installation groove 9. The mounting hole 7.3 corresponds to the screw hole in the installation groove 9 and is locked and fixed by screws. After connection, the pressing plate 7.2 is located outside the gland 2. At the same time, a mounting hole is provided on the side wall of the front end of the gland 2, and the linkage rod 8 is installed in the mounting hole.

[0029] The specific operation of this device is as follows: When cutting the optical fiber, first open the gland 2. During the opening process, the linkage rod 8 drives the arc plate 4.1 to turn upwards. The arc plate 4.1 drives the cover plate 3.2 to open. Place the optical fiber into the optical fiber groove of the fixture base 3.1, and then cover the gland 2. During the closing process, under the action of the pressure rod 7, the pressure rod 7 pushes the arc plate 4.1. The arc plate 4.1 drives the cover plate 3.2 to rotate and close. Under the action of the pressure pad 6, the optical fiber is tightly pressed for cutting. After cutting is completed, open the cover plate 3.2 to open the cover. This solution realizes the linkage effect between the gland 2 and the cover plate 3.2, reduces the actions of clamping the optical fiber by the optical fiber fixture alone and installing the optical fiber fixture, has a simple operation, and greatly saves the operation steps of the existing optical fiber cutter.
