[0002] The QBH (Quick Bayonet Hold) fiber optic connector is a fiber optic connector designed specifically for the transmission of high-power fiber lasers, and has the characteristics of easy operation, high stability, and resistance to environmental impact. This type of connector is widely used in laser cutting, welding, and marking equipment, especially in the industrial, military, medical, and scientific research fields. During the maintenance process of the QBH fiber optic interface, disassembly and installation are inevitably involved. In order to reduce the risk of breaking the fiber crystal end during the disassembly and installation of the QBH fiber optic interface, a QBH fiber optic interface plugging and unplugging auxiliary device is proposed.
