Therefore, the operator has a buffering time before moving the first connecting shell 32 away from the fiber adapter 4 by dialing the tail sleeve 2, which reduces the possibility of wrong operation for the user to some extent. It should be added that the second connecting shell 33 also serves for the connecting function. The operator only stirs the tail sleeve 2 to realize unlocking, and the operation does not influence the splicing of other optical fiber connectors and other adapters, so that the optical fiber connector has the advantages of convenience in operation, cost saving and good plugging effect.
