A kind of sine pulls to stretch cell to add to carry device, involve a medical science experiment instrument in of the cell mechanics add to carry device. The invention mainly includes a machine, wheel gear deceleration to adjust soon electrical engineering, number to show to adjust soon a machine, crank a slippery piece organization and pulls to stretch sport organization. The crank slips a piece of organization mainly from adjust a pole, the song arm slippery piece, crank and pull pole composing; Pull to stretch sport organization mainly from glide a support, fix support, direction pole, pioneer pole piece and behind lead a pole piece composing. Because the invention has structure simple, operate simple, maintenance convenience, the cost is cheap, circulating steady, sex price ratio high, the cell is subjected to dint even, can regulate to pull to stretch characteristics, such as range and frequency...etc., pull to stretch distance can the convenience regulates within the scope of 0~25 mm, can satisfy various cell which stick a wall growth to carry on the mechanics incitement which pulls to stretch to add to carry to respond to a research, so the invention can used to the cell mechanics within instrument of the medical science experiment to add to carry device extensively, being applicable to funds and profession to operate the think factory that the personnel lacks specially extensively applied.
