摘要： The borer apparatus for an embroidering machine comprises a device for removably mounting an exchangeable borer implement on a borer support. The exchangeable borer implement is secured against rotation and is axially fixed by a pivotable hairpin spring which facilitates the replacement of the exchangeable borer implement. The exchangeable borer implement is inserted with its shaft into a sliding or close fitting bore in the borer support and a stop member in the close fitting bore engages an end or head groove of the shaft of the exchangeable borer implement. The shaft is subjected to the action of the hairpin spring in order to secure such shaft against inadvertent rotation. The stop member in the close fitting bore is formed by a pin or sleeve which penetrates and protrudes out of at least one side of the borer support and whose free end forms a biasing stop for the free end of the outwardly pivotably positioned hairpin spring which fixes the exchangeable borer implement in an axial direction. The hairpin spring has a clamping shank which engages a contact surface on the shaft of the exchangeable borer implement. The contact surface extends vertically in relation to the longitudinal roll axis of the exchangeable borer implement.
