Further, a left side portion of the floating thrust portion 111 facing one end of the key cylinder 10 is provided with a first inclined surface 114, a right side portion of the floating thrust portion 111 facing one end of the hole of the key cylinder 10 is provided with a second inclined surface 112, and a turning angle 113 is formed between the first inclined surface 114 and the second inclined surface 112. The turning angle 113 may be a sharp transition or a rounded transition. Two inclined surfaces are respectively arranged on two sides of one end, facing the hole of the lock cylinder 10, of the floating bearing and pushing part 111, so that the friction resistance between the wheels and the floating plate 11 can be reduced, and the smoothness of unlocking is improved.
