By use of the resonating group method, the \ensuremathΔK,\ensuremathΛK, and \ensuremathΣK states are further dynamically studied in the extended chiral SU(3) quark model based on our previous work. Similar to the results given by the original chiral SU(3) quark model, the calculated results here still show that the interactions of \ensuremathΔK with isospin I=1 and \ensuremathΣK with isospin I=1/2 are attractive, which can consequently lead to \ensuremathΔK and \ensuremathΣK quasibound states. When the channel coupling of \ensuremathΛK and \ensuremathΣK is considered, the calculated phase shifts show a sharp resonance between the thresholds of these two channels with spin parity JP=1/2^\ensuremath-.
