A safety tongs linkage mechanism comprises linkage sleeves, first lifting rods and second lifting rods. An inner sleeve and a spiral guide rail are arranged in each linkage sleeve. The first lifting rods penetrate through the inner sleeves and are meshed with threads of the inner sleeves, and the first lifting rods drive the spiral guide rails to rotate during lifting so as to drive the second lifting rods to act. Multiple types of linkage sleeves are included. The time that the second lifting rods lag behind the first lifting rods can be completely achieved by selecting linkage sleeves of different types, and gaps between movable wedge blocks and guide rails do not need to be calibrated.

    一种安全钳联动机构包括联动套、提拉杆一和提拉杆二,联动套中设置了内套和螺旋导轨,提拉杆一穿过内套并与内套的螺纹啮合,提拉杆一在进行提拉时带动螺旋导轨旋转,从而带动提拉杆二动作,联动套包括多个型号,提拉杆二滞后提拉杆一的时间完全可以根据选择不同型号的联动套来实现,而不需要再校准活动楔块与导轨之间的间隙。
