Each rotary dial of the symmetrical rotary dial 4 is in a 5-00 dense position fan-shaped structure, the long scale line corresponds to a 1-00 dense position, and the short scale line corresponds to a 0-20 dense position. As shown in figure 3, 14 rotating positioning concave points 18 are arranged on the outer ring of a hollow rotating shaft 17 of the cross main body bracket 1, and are arranged at intervals of 30 degrees from 15 degrees in a clockwise direction from the north direction to the center of the

bracket arm

14, and 2 rotating positioning concave points are arranged at 0 degree and 180 degrees. Two symmetrical rotary positioning salient points 42 are designed on the outer side of the rotating shaft hole 41 on the symmetrical axis of the corresponding symmetrical rotary dial 4, and the rotary positioning salient points 42 are clamped into the rotary positioning concave points 18 to position the symmetrical rotary dial 4. The bracket arms in four directions and the scales of the symmetrical rotary dial 1 are combined and applied.

When the symmetrical rotary dial is in a reading state, the azimuth angle of the target point at any position can be accurately read only by rotating the symmetrical rotary dial for 6 times. A circular disc is added in the middle of the symmetrical rotary dial to connect the two symmetrical dials, and right-angle reading auxiliary scale marks corresponding to positioning points are designed on the circular disc.

The terminal connecting plug 67 that sets up of odometer support 61, the middle part is opened has the mounting groove, and kilometer gear 62 and volume reading gyro wheel 63 are installed in the mounting groove through the pivot. The outer edge of the reading roller 63 is designed with anti-slip teeth, and the side surface of the reading roller 63 is designed with a transmission column 65 which is meshed with the kilometer gear 62 and transmits. One side of the odometer bracket 61 is also provided with a magnifying glass 66 which is positioned above the tooth surface of the kilometer gear 62. As shown in fig. 26, the odometer unit 6 is inserted into the connection jack 16 at the front end of the south bracket arm 12 through the connection plug 67 to be combined for use, so as to form an upper-range capacity reading function area. Because the metering roller in the odometer assembly is a precision component, an anti-collision protective outer sleeve 62 is added during the design process. As shown in fig. 25, 2cm of the circumferential length of the gauge roller 63 (corresponding to a length of 1km on a 1: 5-thousand military topographic map) corresponds to a diameter of 6.3694 mm. The outer edge of the measuring and reading roller 63 is provided with anti-skid teeth, each two sides are provided with a scale mark at the interval of 2mm, the starting position is marked by a red line, and each scale mark is correspondingly marked with '0' to '9'. The transmission column 65 drives the kilometer gear 62 to rotate 1 grid every 1 revolution. As shown in fig. 24, the kilometer gear 62 is a 10-tooth rotating wheel, the gears are equally spaced, and one side of the kilometer gear is marked with "0" to "9", which means that the maximum number of kilometers is 10 km. When the odometer component is in an open state (namely when the anti-collision protection external device is turned on), the magnifier can directly read the numbers from 0 to 9 on the kilometer gear disc. Therefore, when the odometer component is used, the whole kilometer number is directly read from the magnifier, and the hectometer distance below the whole kilometer is directly read from the position of the scale mark corresponding to the reading roller. The kilometer gear is driven to rotate for 1 lattice by the measuring roller transmission column per rotation, the number of kilometers read by the side identification quantity of the kilometer gear disc is 1km-10km, and the value of the odometer is directly read through the amplifying lens.
