The Development and Application of Connection Device for Level Tripod

The connecting screw of level tripod is easy to drop, so a connection device for level tripod is independently developed to overcome the shortcoming. The device that is easy to make and low in cost consists of a connecting screw and a coulisse. The experimental teaching and practice have indicated that the device can not only secure the firm connection between the level and the tripod, but also prevent the connecting screw falling off from the coulisse when using or moving the tripod. The restructuring has both increased the effect of level tripod and met the professional needs, thereby improving the teaching quality significantly.
