<p>A spike assembly has a spike (22) and spike connector (10). The spike connector (10) has multiple threads formed on an inner surface. The multiple threads include a specific thread (13) has a width larger than that of the others. The spike (22) has multiple grooves formed in an outer surface. The multiple grooves include a specific groove (24) having a depth deeper than that of the others and corresponding to the width of the specific thread on the spike connector. Accordingly, the spike is easily connected with the spike connect at a specific orientation, and to assemble the spike assembly is convenient.</p> |
