| description | The utility model provides a fixed marker post for engineering surveying and mapping, and relates to the field of engineering surveying and mapping. The fixed marker post for engineering surveying and mapping comprises a fixed ring, pedals are fixedly connected to the front end and the rear end of the fixed ring, three insertion rods are connected to the bottom end of the fixed ring in an array mode, a supporting frame is fixedly connected to the position, close to the center, of the top end of the fixed ring, and a limiting ring is fixedly connected to the bottom end of the top of the supporting frame; the outer surface of the rolling wheel is rotatably connected with a rotating ring, the end, away from the rolling wheel, of the rotating ring is fixedly connected with a connecting rod, and a rolling ball is embedded in the bottom end of the connecting rod. When the fixed marker post for engineering surveying and mapping is used, the swing rod swings under the gravity effect of the balancing weight, the swing |
