[0002] Fasteners are a general term for a class of mechanical parts used to firmly connect two or more parts (or components) into a whole.

[0003] During the process of using the blanking mechanism of fasteners, screw fasteners may be blocked in the storage device due to reasons such as mutual entanglement, size differences, or foreign matter mixing, resulting in insufficient positioning accuracy and inability to accurately transport the screw fasteners to the appropriate position for use. At the same time, there may also be problems of chaotic sorting of fasteners during the transportation process. For this reason, we propose a blanking mechanism for screw fasteners used in small household appliances, so as to orderly transport the screw fasteners to the designated position.
