摘要 |
A chuck for use with a manual or powered driver having a rotatable drive shaft is provided. The chuck comprises a generally cylindrical body member. The body member has a forward section and a rearward section. The rearward section has an axial bore formed therein to mate with the drive shaft of the driver. A generally cylindrical sleeve is received over the forward section of the body. A primary retaining mechanism is in engagement with the sleeve and the body member to operatively prevent forward axial movement of the sleeve with respect to the body. A secondary retaining mechanism is attached to the sleeve so that if the primary retaining mechanism fails to prevent forward axial movement of the sleeve with respect to the body, the secondary retaining mechanism is brought to engagement with the body to prevent forward axial movement of the sleeve with respect to the body following the engagement. |
