Jig for optical fiber head

The invention provides a jig for an optical fiber head, which comprises an optical fiber head and a jig. The periphery of one end portion of a fiber-optic wire is held by a headstock. The optical fiber head is embedded onto an alignment base on a machine bed to be positioned by the jig. The jig is provided with a frame hole and a positioning part. The headstock is accommodated in the frame hole. The positioning part is used for embedding the optical fiber head onto the alignment base to position the optical fiber head. In this way, the end portion of the fiber-optic wire can be generally positioned within a required machining region to be exposed to the outside.
