Abstract
Description
Technical Field
[0001] The utility model relates to the field of optical fiber fusion splicing machines, in particular to a high-definition optical fiber fusion splicing machine lens. Background Art
[0002] Fiber fusion splicers generally work on optical fibers and optical cables. Generally, they generate high-voltage arcs through electrodes to merge two optical fibers into one for use, so they are also called optical cable fusion splicers. The main function of fusion splicers is to facilitate the maintenance and emergency repair of optical fiber cable lines. Since it is difficult to perform fusion splicing on optical fibers with the naked eye, the operation of fiber fusion splicers is very dependent on the lens inside the fiber fusion splicer. Through the lens, the fusion process and fusion effect of the optical fiber can be observed more intuitively and clearly. However, during the use of existing fiber fusion splicers, it is easy to cause wear and tear on the lens, resulting in damage to the lens and inability to use it, causing the fiber fusion splicer to fail to work properly. In addition, the traditional lens is installed as a whole on the fusion splicer. If there is a fault, it is inconvenient to remove it for maintenance.

[0004] When the detection lens 21 is working, it is necessary to adjust the angle according to the usage. When adjusting, the above patent is adjusted manually. In actual operation, there are the following disadvantages:
[0005] Manual adjustment may be difficult to achieve high precision requirements, especially when fine-tuning the angle is required; this may lead to reduced welding quality and increase the risk of connection failure;
[0006] Manual adjustment requires operators to spend more time and energy, which will reduce work efficiency. Utility Model Content
