[0002] Optical fiber fusion splicer is the high-tech instrument and equipment combined with optics, electronic technology and precision machinery. It is mainly used for the construction and maintenance of optical cable in optical communication, so it is also called optical cable fusion splicer. The general working principle is to use high-voltage arc to melt the two optical fiber sections, and at the same time, use high-precision motion mechanism to gently push the two optical fibers to fuse into one. The fused optical fiber has the characteristics of low loss and high mechanical strength, so that the optical fiber mode field is realized, and the signal is effectively transmitted. When the optical fiber fusion splicer is used, the heater base needs to be controlled to heat the optical fiber.

[0003] However, during the operation of the optical fiber fusion splicer, after the optical fiber is fused, the operator needs to open the heater cover, put the fused optical fiber into the heat shrink tube and then put it into the heater base. Then close the heater cover, heat it, open the heater cover and take out the optical fiber. After a series of operations, the optical fiber heat shrinkage is completed. In this operation process, the steps are relatively complicated and time-consuming. At the same time, due to the different types of optical fibers, the heating operation of the heat shrink tube with different diameters is inconsistent in the heating process, which causes the heat shrink tube to be unevenly heated. Therefore, we propose an automatic opening and closing device. UTILITY MODEL CONTENTS
