A pair of chopsticks includes two elongate bodies facing each other, and a connector pivotally connected with and between the two elongate bodies. The elongate bodies respectively have a hollow near an upper end. The connector has a plate spring, which has one end pivotally connected to the hollow of each elongate body. Thus the connector connects the two elongate bodies together so that the lower end sections of the two elongate bodies may be closed by pushing the two bodies inward to each other for picking up food, and opened by letting loose a hand clamping the two bodies for next round of picking up food.
