1. A detachment-resistant shell of light bulb, comprising:
a base, which has a lower end forming an opening around which a first coupling section is circumferentially formed, the first coupling section having a side face around which a thread is circumferentially formed, the first coupling section having a top face on which a plurality of teeth is formed and distributed circumferentially, each of the teeth having a straight side; and a cover, which has an upper end forming an opening that forms a second coupling section corresponding to and engageable with the first coupling section, the second coupling section having a counterpart side face that corresponds to the side face and around which a counterpart thread is circumferentially formed to correspond to and be engageable with the thread, the second coupling section having a counterpart top face that corresponds to the top face and forms at least one resiliently deflectable member, the resiliently deflectable member being provided with a counterpart tooth that corresponds to and is engageable with the teeth, the counterpart tooth comprising a counterpart straight side corresponding to the straight side, the counterpart straight side of the counterpart tooth being selectively engageable with the straight side of one of the teeth to constrain reverse rotation. |
