The invention discloses a long-span double-end quick insertion and extraction positioning mechanism and method. The mechanism comprises a lifting and pressing rod, the two sides of the lower portion of the lifting and pressing rod are hinged to one end of a two-force rod, the other end of the two-force rod is hinged to one end of a spring compression rod, and a compression spring is arranged on the spring compression rod, close to one end of the two-force rod and fixed to the spring compression rod; the spring compression rod can move in the horizontal inner cavity of the lower shell in the axial direction of the spring compression rod. When the lifting and pressing rod moves up and down, the two-force rod can be pulled to move, and the two-force rod can pull the spring compression rod to move in the axial direction of the spring compression rod. The structure is simple and reliable, and the mechanism is stably pressed and locked.
