Advantage of the present utility model is: simple in structure, easy to use, lockset can not opened easily, has improved the safety of lockset.

Description of drawings:

Fig. 1 is the perspective exploded view of lockset commonly used;

Fig. 2, Fig. 3 are perspective exploded view of the present utility model;

Fig. 4 is an embodiment schematic diagram of the present utility model.

The specific embodiment:

Shown in accompanying drawing 2 and accompanying drawing 3, the utility model mainly comprises a lock 4, a core 5, a snap-latch piece 6 and a key 7, wherein, these lock 4 eccentric positions are provided with vertical hole 41 of round shape, be provided with the most groovings that are 90 degree with vertical hole 41 in these vertical hole 41 inner edges, for inserting spring 42 and fore-set 43;

Core 5 is slightly less than vertical hole 41 of lock 4, it is provided with a slot 51, and in being the through hole 52 that 90 directions of spending are provided with majority with this slot 51, make these through holes 52 be mutual perforation with slot 51, and insert the fore-set 53 of different length, and be provided with a location steel ball 54 in least significant end in these through holes 52;

The surface of key 7 is provided with tooth portion 71, is provided with the groove 72 of different weights in its side;

Combination by aforementioned components, after this core 5 is placed on vertical hole 41 of lock 4, connect a snap-latch piece 6 to constitute a lockset in the core end, behind the slot 51 by key 7 insertion cores 5, make its tooth portion 71 and groove 72 that the fore- set 53,43 of core 5 and lock 4 is given the top whetstone respectively with core 5 rotations, and then rotate snap-latch piece 6 lockset is opened, if the tooth portion 71 of key 7 and groove 72 are not then opening at once with fore- set 53,43;

Aforesaid lockset is owing to be provided with the fore-set 43 of lock 4 and the fore-set 53 of core 5, therefore, if when the burglar desires to pry open lockset with unlocking tool, can't back down fore-set 43,53 simultaneously with instrument, and with core 5 rotations, therefore, the utility model can reach excellent safety and anti-theft effect.

As shown in Figure 4, after the utility model combination, its core 5 is positioned at the eccentric position of lock 4, when key 7 after inserting slot 51, can respectively fore-set 53,43 be given the top whetstone by the groove 72 of its surperficial tooth portion 71 and side, make core 5 be free state, again core 5 is rotated, after rotating, be able to the location of invar pearl 54, the demonstration of unblanking with formation, make unlock operation more convenient, and because of the burglar can't be simultaneously with fore-set 43,53 top whetstones, the safety that has improved lockset.
