<p>A portable key assembly occupies less space and is attachable to certain attachment structures for providing a key-turning moment arm. The portable key assembly is set with a key body, a lock fastener, and an abbreviated key handle on one end of the key body. The portable key assembly can be connected and overlapped in face-to-face relation with other keys or key accessories so that the same may be well combined, easily located, and convenient to carry. A moment arm extension can be formed by connecting the portable key assembly with other keys or key accessories. The turning torque of the key handle may thus be enlarged so that the portable key assembly can function properly even if the key handle is shortened and the volume of the whole key is reduced.</p> |
