[0024] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the utility model is an adjustable one-step optical fiber cleaver, comprising a support block 1, a base 4, a swing arm 8 and an upper cover 3, wherein the support block 1 is arranged at one end of the base 4, and a plurality of fixing parts are protruded from the support block 1, and a bearing 18 is embedded in the fixing part, and a shaft 9 is installed between the bearings 18, and the upper cover 3 is arranged on the swing arm 8, and one end of the swing arm 8 is protruded to form a plurality of first connecting parts 6, and one end of the upper cover 3 is protruded to form a plurality of second connecting parts 7, and the first connecting parts 6 and the second connecting parts 7 are both sleeved on the shaft 9, and a fixing screw 2 is installed on the support block 1 to synchronously fix the support block 1, the swing arm 8 and the upper cover 3 to the base 4;

[0025] The bearing is fixed to the fixing portion by a slotted screw 19 , and the first connecting portion 6 is fixed to the shaft 9 by a machine screw 20 .

[0026] In this embodiment, a plurality of grooves 17 are provided on the outer surface of the support block 1, and the inner wall surfaces of the grooves 17 are provided with through holes 12 that penetrate the support block 1. The base 4 is provided with screw holes 16 at positions opposite to the through holes 12. The fixing screws 2 are arranged inside the through holes 12, and the screw rods of the fixing screws 2 are threadedly connected to the screw holes 16. The screw heads at the other ends of the fixing screws 2 are arranged in the grooves 17. An avoidance space is formed between the grooves 17 and the screw heads and between the screw rods and the through holes 12 for the support block 1 to move up, down, left and right.

[0027] In this embodiment, a torsion spring 5 is sleeved on the middle of the shaft 9 . One end of the torsion spring 5 is mounted on the base 4 , and the other end is fixedly connected to the upper cover 3 .

[0028] In this embodiment, a cleaning port is provided on the bottom surface of the base 4, in which a bottom plate 13 is mounted by snaps. Once the cleaning port becomes too dirty, the bottom plate can be opened so that the interior can be cleaned.

[0029] In this embodiment, a knife seat 14 is installed inside the base 4, and a blade 15 is installed on the knife seat 14. After the swing arm and the upper cover are pressed down with the shaft as the center, the optical fiber and the blade can be cut, thereby cutting off an excess section of optical fiber.
