The specific embodiment

For enabling to further specify architectural feature of the present utility model and practical effect, describe in detail as the back with preferred embodiment conjunction with figs. hereinafter described now:

The utility model is a kind of lock cylinder device of lockset, please referring to Fig. 1 to Fig. 3, comprising:

One core 10, core 10 is one cylinder-shaped, be provided with together axially and be the lockhole 11 of ♂ shape by an end face, a vertical place, lockhole 11 tops is Zhi Suokong 111, supply key 40 through this insertion, core 10 is laterally to be provided with several to be parallel intermediary's groove 12 mutually by Zhi Suokong 111 1 sides that communicate, the end of intermediary's groove 12 is to expand to be made as to allow the following hole of bead 13 of lock pearl 14 arrangements down, the following hole of bead 13 communicates with lockhole 11, being side direction with Zhi Suokong 111 communicates, allow the key 40 must be by Zhi Suokong 111 towards intermediary's groove 12 rotation and enter down the hole of bead 13, in addition at parallel adjacent intermediary groove 12 and be positioned at locating foremost that key 40 inserts, be provided be recessed into together put groove 15, putting groove 15 openings is to be the pass 16 that dwindles shape, the both sides in pass 16 are for supporting edge 161, in order to as shown in Figure 1 and Figure 4, supporting edge 161 and putting and settle a returning spring 17 between groove 15 inner faces;
