The appearance hole of locking plate is designed to two kinds of specifications, places the appearance hole width of core inner segment less, and bigger near outer section appearance hole of lockhole, key need cooperate the appearance hole width of locking plate, also is divided into two sections, and promptly the outer end is thinner, and thicker near the grip part.

Following embodiment will be further described structure of the present utility model and outstanding effect in conjunction with the accompanying drawings.

Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model.

As shown in Figure 1, this lockset comprises the collar 1, core 2, locking plate 3, pin 4, lock housing 5 and key 6.At least 2 group locking plates 3 are set, the corresponding design of short slot of locking plate 3 and key 6 in the cylindrical shell 21 of core 2.Locking plate 3 central authorities form the appearance hole 31 of S shape, this appearance hole inwardly is convexly equipped with lug 32 by the upper aperture limit, and near its edge, below lug 33 is then bigger apart from lower edge, top lug 32 is bigger apart from its each side plate edge than below lug 33 in other words, make to hold small one and large one S shape hole of the 31 one-tenth upper and lower holes in hole, or the shape of falling S hole.In addition, be provided with two

corresponding arc notch

34,35 and protrude the tuck pointing sheet 36 of locking plate outer rim in the outer rim of locking plate, the tuck pointing sheet just is positioned at the corresponding surface in the middle of two arc notch 34,35.Pin 4 is the L type, and at its short jag 42 sheathed springs 43, this pin body 41 can be embedded in the embeded slot 22 of core simplified 21.In addition, two or more drift slots 51 can be set in lock housing 5.
