  3. 根据权利要求2所述的一种改进缓冲铰链，其特征在于：第二连动件位于导向机架两侧设置传动杆件，导向机架两侧设 置一供传动杆件插接或穿过的第一凹口部或通孔，传动杆件传动于导向机架两侧的第一凹口部或通孔处
  4. 根据权利要求2所述的一种改进缓冲铰链，其特征在于：传动杆件包括：第二连动件位于导向机架的两侧分别设置拉轴，两侧拉轴插接于导向机架两侧的第一凹口部或通孔处。
  5. 根据权利要求2所述的一种改进缓冲铰链，其特征在于：传动杆件包括：第二连动件位于导向机架的两侧设置传动轴，传动轴穿设于导向机架两侧的第一凹口部或通孔处。
  6. 根据权利要求3所述的一种改进缓冲铰链，其特征在于：第二连动件的一端设置往其导向机架两侧延伸的传动部，传动部与传动杆件铰接。
  7. 根据权利要求3所述的一种改进缓冲铰链，其特征在于：定位块的两端具有用于承托导向机架的凸沿。
  8. 根据权利要求5所述的一种改进缓冲铰链，其特征在于：定位块两侧凸沿对应第二转轴设置第二凹口部。
  9. 根据权利要求1-6任一项所述的一种改进缓冲铰链，其特征在于：上述的挡止部为设置在扭力弹簧与阻尼器的活塞杆之间的挡块或挡板或隔档轴孔或间隙小于活塞杆直径的挡止格栅。
  10. 根据权利要求2所述的一种改进缓冲铰链，其特征在于：其在位于扭力弹簧与阻尼器的活塞杆之间设置的为挡板，挡板由外壳外侧沿其内侧折弯设置或设置于外壳的两侧板之间。
  11. 根据权利要求7所述的一种改进缓冲铰链，其特征在于：导向机架包括两侧板以及连接两侧板的底部形成的夹口形状，定位块置于导向机架的两侧板之间。
