ABSTRACT:
A telescopic chopstick including an upper section, a lower section and a press member. The upper section is a hollow rod formed with an upper opening and a lower opening. A locating section is formed on an inner side of the upper section. The lower section has an upper end and a lower end. The upper end has a peripheral length larger than a peripheral length of the lower end. The upper end of the lower section has a connecting section for engaging with the lower end of the upper section. The press member is fitted in the upper opening of the upper section and located by the locating section of the upper section. A leaf spring integrally extends from a bottom end of the press member. When the lower section is retracted into the upper section, the leaf spring resiliently abuts against and engages with a lateral wall of the connecting section of the lower section. The lower section can be easily taken out from the upper opening of the upper section for washing.
