The balls are made of bearing steel, are equal in size and distance and are arranged at intervals.
The bearing structure is composed of the cylindrical outer frame body, the cylindrical inner frame body and the balls, can reduce the friction coefficient of the cylindrical inner frame body in the rotating process, and has certain bearing capacity.
The utility model relates to a be applicable to that levelling staff is fixed and prevent device that sinks, its advantage lies in: 1) and the measurement error is reduced, and the measurement precision is improved. The introduction of this device has replaced the ruler pad that need lay when the turning point, has eliminated the error that vertical position skew caused when the levelling staff is rotatory on the ruler pad, has eliminated the error that the instability that manpower was held up the chi caused simultaneously. 2) Convenient and fast, raise the efficiency. This device collects the fixed of levelling rod and prevents sinking two functions in an organic whole, and laying of instrument is simple, and maneuverability is strong, and work efficiency is high. 3) The labor intensity is low. The device realizes the mechanization of the holding ruler work, does not need the manual holding ruler of a measurer in the measuring process, and greatly reduces the workload. 4) The use mode is flexible, is applicable to the levelling staff of different size specifications. 5) Has wide application prospect. The device changes the traditional method, greatly improves the working efficiency and has wide application prospect.
