    • The dampening device comprises a first member, preferably a tubular member, which is to be positioned at the end of the surveying rod which is to be directed to the ground, a second member, preferably a post, being at least partially slidable directly or indirectly along the first member in a longitudinal direction and for being directly or indirectly connected to a tip which is to be placed on the ground, wherein the first and second members overlap at least in one position at least partially along the longitudinal direction, and at least one elastic dampening member which is directly or indirectly housed by the first and/or second member and disposed such that it is compressed by a movement of the first member and the second member relative to each other in the longitudinal direction, so that mechanical shock exerted to the surveying rod and/or the tip can be dampened by elastic deformation of the dampening member.
    • 阻尼装置包括第一构件,优选地为管状构件,其将位于测量杆的要被引导到地面的端部处,第二构件,优选地为柱,其可以直接或间接地至少部分地滑动 沿纵向方向沿着第一构件并且直接或间接地连接到要放置在地面上的尖端,其中第一和第二构件至少在一个位置上至少部分地沿着纵向方向重叠,并且至少 一个弹性阻尼构件,其由第一和/或第二构件直接或间接地容纳并且被布置成使得其通过第一构件和第二构件在纵向方向上相对于彼此的运动而被压缩,使得施加机械冲击 到测量杆和/或尖端可以通过阻尼构件的弹性变形来衰减。
