Zusammenfassung:	The invention relates to axial circumferential double localized key. Its features are that the key width embedded in shaft key way is W; its total length L is bigger than the length L1 lain in shaft key way; its thickness D is divided into three parts that d1 lain in the shaft key way, d2 blocked in the water wheel key way, the rest exposed out of the water wheel. Its working includes the following steps: laying the key on the shaft; right facing the water wheel key way; shaft lengthwise holding tightly; tweaking sealed end cover. Its advantages are that water wheel center cavity can be well connected with the hollow axle inner; the assembling and disassembling for radial terminal strand and pin are very convenient; it is simple, feasible, and has strong practicability.
