Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Fig. 1~2, the present invention includes movable shell 1, fixing shell 2, mouthpiece 7, flexible member 13, mounting seat
12 and resilient contact 4, wherein mouthpiece 7 is packed on host machine casing 3 by locking element 8, and the locking element 8 is this area
Known technology, one end that laser generator end lock pin 6 is located inside main frame by the mouthpiece 7 is inserted, optical fiber handle end lock pin
11 one end for being located at outside main frame by the mouthpiece 7 are inserted, and laser generator end lock pin 6 and optical fiber handle end lock pin
11 in the internal end surface of mouthpiece 7 coupling, and the fixing shell 2 is fixedly arranged on the outside of host machine casing 3, and movable shell 1 may move
Ground is arranged on the free end of fixing shell 2, and the fixing shell 2 and movable shell 1 are set in the mouthpiece 7
On, flexible member 13, mounting seat 12 and resilient contact 4 are provided with the fixing shell 2, wherein the mounting seat 12 is fixedly arranged on
On host machine casing 3, the flexible member 13 is arranged in the mounting seat 12, and the flexible member 13 is away from host machine casing 3
One end is connected with the bottom side of movable shell 1, and conductive ring 9 is provided with the bottom side of movable shell 1, in the mounting seat 12 and admittedly
Determine to be provided with resilient contact 4 between shell 2, drive the movement of movable shell 1 that the conductive ring 9 can be made to be contacted with resilient contact 4
Form loop.In the present embodiment, the flexible member 13 is back-moving spring.
As shown in Fig. 1~2, optical fiber handle end lock pin 11 is inserted after the mouthpiece 7 by a lock of external locking set 10
Fasten, and when optical fiber handle end lock pin 11 is docked with the mouthpiece 7, the external locking set 10 can prop up the work
The dynamic movement of the shell 1 compression flexible member 13, and the conductive ring 9 is contacted with resilient contact 4, outwards screw the outside
During lock sleeve 10, the movable shell 1 automatically resets under the flexible member 13 effect.The movable shell 1 is outer with fixing
