Automatic public-private dual-purpose chopsticks

Abstract

The invention relates to the technical field of tableware, in particular to automatic public-private dual-purpose chopsticks. The chopsticks comprise male chopsticks and private chopsticks, through holes are formed in the private chopsticks in the axial direction; the male chopsticks are arranged in the through holes in an up-down sliding manner; blind holes are formed in the upper ends of the male chopsticks in the axial direction; nuts are fixed at the upper end of the blind holes; a driving mechanism and a screw rod connected with the driving mechanism are arranged in the through holes; thelead screw is connected with the nuts to form a lead screw nut mechanism; a positioning structure is arranged between the male chopsticks and the private chopsticks; the positioning structure prevents the male chopsticks from rotating relative to the private chopsticks; the driving mechanism drives the lead screw to rotate, and the nuts in the lead screw nut mechanism does linear motion along thelead screw, so that the nuts drive the male chopsticks to slide in the through holes of the private chopsticks, the male chopsticks can quickly extend out of the private chopsticks, the workload of adjusting the position relation between the male chopsticks and the private chopsticks is reduced, the male chopsticks can automatically enter and exit from the private chopsticks, and the labor amountof diners is reduced.
