[0002] At present, in the construction of optical cable erection, the outer insulating sheath of the optical cable is generally stripped by using a conventional electrician's knife. However, the conventional electrician's knife has a single structure and function, inconvenient operation, and due to the different thicknesses of the sheath layers of different optical cables, it is difficult to master the force during stripping, and the optical cable core wire is often damaged, so it has to be stripped again, which is time-consuming and laborious, and also easy to cause waste of optical cable materials. Therefore, an optical cable stripping knife is proposed. Summary of the Invention

The main blade is in a sickle-shaped structure. One end of the second handle is fixedly installed with a sub-blade for axially rotating and stripping the optical cable sheath. The sub-blade is a blade structure with a vertical knife back and an arc-shaped blade edge. A tooth-shaped structure corresponding to the optical cable sheath is arranged in the middle of the arc-shaped blade edge of the sub-blade.

[0027] Further, auxiliary protective rings 16 are fixedly installed on the outer sides of the first handle 1 near the main blade 2 and on the outer sides of the second handle 3 near the secondary blade 4 respectively. The auxiliary protective rings 16 play a role in auxiliary protection to prevent the blade from hurting the hand when the operator's hand slips.

The anti-slip groove patterns 17 play a role in auxiliary anti-slip.

[0029] During use:

[0030] First, through the tooth-shaped structure 13 on the secondary blade 4, the outer sheath of the optical cable is axially circumferentially stripped (due to the limitation of the tooth-shaped structure 13, only a relatively shallow circumferential stripping is performed on the outer sheath of the optical cable, and it is not easy to damage the optical cable core). Then, the main blade 2 with a sickle-shaped structure performs a lateral stripping operation along the radial direction on the optical cable with the sheath already stripped (since the sheath has been stripped, the internal optical cable core can be seen and the optical cable core will not be damaged).

[0031] Through the threaded adjustment of the first threaded hole 5 and the first threaded rod 6, the distance between the first handle 1 and the main blade 2 can be adjusted according to the usage needs. Moreover, according to the usage needs, the first threaded rod 6 can be separated from the first threaded hole 5, and the main blade 2 can be inserted into the first threaded hole 5, and the second threaded rod 8 can be screwed tightly with the first threaded hole 5, which is convenient for storing the main blade 2 when not in use and is convenient for safe storage and carrying.

[0034] Our optical cable stripping knife adopts a tooth-shaped structure, which consists of a main knife and a secondary knife. The secondary knife is used for stripping the sheath of the optical cable interface, and the main knife is used for lateral stripping of the optical cable, saving time and effort, and completing the optical cable stripping work at one time.
