A length adjustable lock cylinder comprises a front lock body assembly 100, a rear lock body assembly 200, and expansion assembly 400 attached to a fixed mounting base 500 which is provided with a plurality of mounting holes 502 and fixing columns 503. A cam 300 is arranged in the middle of the expansion assembly. The expansion assembly comprises a plurality of expansion sheets 401. The front lock body assembly 100 comprises a rotating handle 103, lock cylinder 102, an outer lock shell 201, and a lock rod 105 connected to said cylinder. The rear lock body assembly comprises a connecting rod 203 arranged inside a shifting rod 202. The lock rod 105 may be provided with an eccentric part designed to push a locking mechanism 110 upwards upon insertion of a key and rotation of the locking cylinder. A pin 113 included in the locking mechanism may engage an elongate slot 204 in the shifting rod linking the outer lock shell and shifting wheel rotationally. The shifting rod may then rotate the cam. The outer lock shell may be rotationally coupled to the connecting rod provided with a ratchet 602. Allowing the arrangement to be locked without insertion of a key.
