Abstract
A push-chain includes a plurality of push-chain links, each push-chain link of the plurality of push-chain links including two strip-shaped mounting pieces disposed opposite one another and one connecting piece that connects at most half of an end face of the two mounting pieces at one side. Each of the two mounting pieces is provided with two mounting holes in the length direction. A distance between the two mounting holes is equal to half the length of the mounting piece. The mounting holes on the two mounting pieces are arranged opposite one another, and two corners on another side of each of the two mounting pieces are rounded corners allowing the push-chain to bend. Two adjacent push-chain links of the plurality of push-chain links are hinge-connected in a horizontally staggered arrangement by way of a chain pivot and the mounting holes.
