Fastening column used for plastic packaging of motor and plastic packaging motor

The utility model discloses a fastening column used for plastic packaging of a motor and a plastic packaging motor. The fastening column comprises a column body. A screw hole is formed in an end face of the column body and a projection or a groove is formed on an end face the other end. The column body is tapered. The screw hole is located at the minor diameter end of the column body. The projection or the groove is located at the major diameter end of the column body. The projection or the groove is formed on one end face of the fastening column, thus the projection or the groove of the fastening column after plastic packaging and the plastic packaging motor form matched concave-convex structures, the rotation resistance of the fastening column in a plastic packaging body is raised, rotation of the fastening column is prevented, and safety and reliability of motor operation are raised. The column body has a tapered structure, and can prevent the fastening column packaged in the plastic packaging motor from separation from the plastic packaging motor in the axis direction effectively. The fastening column is reasonable in structure, is easy to manufacture, is low in cost and is safe and reliable.
