A combination lock with a simplified structure is disclosed. The lock includes a male body having an outwardly extending bolt with an axial row of projecting bits formed thereon, and a female body having an outwardly extending tube with an axial narrow opening defined therein. The tube is used for receiving the outwardly extending bolt of the male body in a way of allowing the bits to be protruded therefrom through the axial narrow opening. The tube further has a plurality of axial grooves defined in an outer periphery thereof. A set of dials is mounted around the tube of the female body. Each of the dials has a dial ring, and a hairspring carried on the dial ring and having a pair of curved portions extending inward to engage two of the axial grooves of the tube.
