The lock cylinder body 2 has a lock cylinder inner sleeve 20 and a core body 21 disposed in the lock cylinder inner sleeve 20, the lock cylinder inner sleeve 20 is used to put the core body 21 together from the rear end of the outer sleeve wall 10 of the lock cylinder outer sleeve 1, so that the core body 21 is located inside the outer sleeve wall 10, and the core body 21 is assembled inside the outer sleeve wall 10, i.e. corresponding to the insertion hole 110 on the front end portion 11 of the lock cylinder outer sleeve 1, and maintains a rotatable state with the lock cylinder inner sleeve 20. In the embodiment of the present invention, the lock cylinder inner sleeve 20 has an overlapping space 200, and the core body 21 is formed by alternately stacking a plurality of locking pieces 210 and a plurality of spacers 211, and is limited to be accommodated in the overlapping space 200; each lock piece 210 is provided with a lock hole 210a matched with the corresponding key 4, so that the purpose of unlocking or unlocking can be achieved when the key 4 is inserted.

Referring to fig. 3, the safety member 3 includes a torsion member 30 and a latch member 31. The torsion member 30 is disposed in the lock core housing 1 of the lock core body 2, and the latch member 31 is elastically abutted in a radial direction and disposed between the front end portion 11 of the lock core housing 1 and the torsion member 30, so that the front end portion 11 can be elastically pushed to the torsion member 30 in the radial direction to latch on the front end portion 11 and the torsion member 30 or reversely elastically push the latch member 31 to disengage from the torsion member 30. The torsion member 30 is provided with a confirmation hole 300, the confirmation hole 300 is communicated between the insertion hole 110 of the front end portion 11 and the core body 21, and the latch member 31 is further abutted by an elastic member 310 to elastically push a contact member 311 into the confirmation hole 300.

In addition, in order to facilitate the assembly of the safety component 3, the present invention may further include an assembly hole 111 disposed at the radial direction of the front end portion 11 of the lock cylinder housing 1, and a through hole 301 disposed at the radial direction of the torsion member 30, the elastic member 310 and the locking member 31 may be assembled in the assembly hole 111 from the inside of the front end portion 11 and pressed against each other, and after the contact member 311 is assembled from the outside of the through hole 301, the torsion member 30 is assembled from the rear end of the housing wall 10 and aligned to the locking member 31 by torsion, so that the lock cylinder body 2 is assembled.
