Embodiment
As shown in Figure 1-Figure 3, the utility model comprises: mainboard 1, employing screw connecting mode are arranged on the main scale that can rotate 2 of mainboard 1 one end, the auxiliary chi 3 that can slide that employing screw connecting mode is arranged on mainboard 1 other end, wherein, mainboard 1 is arcuate structure, and mainboard 1 is provided with the digital calibration 1d for taking measurement of an angle above; Mainboard 1 is also provided with two cambered way grooves with the same center of circle, and wherein, a slide groove is auxiliary chi slide groove 1a, and the two ends of auxiliary chi slide groove 1a are the circular arc of mating with auxiliary chi bolt hole 3a; Another slide groove is an auxiliary chi slider slideway groove 1b, and the two ends of auxiliary chi slider slideway groove 1b are the straightsided shape mating with slide block on auxiliary chi 3.
As shown in Figure 4, mainboard 1 is provided with the mainboard bolt hole 1e that a size is mated with tight lock screw 4, in mainboard bolt hole 1e, by tight lock screw 4 and nut 6, rotating main scale 2 is installed; On mainboard 1, be provided with one for stopping the protruding 1c in piece of main scale 2 rotations with main scale 2 adjacent positions.
As shown in Fig. 5-Fig. 6, main scale 2 be shaped as flechette-type, the top of main scale 2 is provided with a main scale bolt hole 2a for being connected with mainboard 1; By tight lock screw 4 and nut 6, main scale 2 is arranged in mainboard bolt hole 1e and main scale bolt hole 2a, main scale 2 can utilize tight lock screw 4 rotations on mainboard 1, also can rest in the place of 1c in piece of mainboard 1 projection; The pros and cons of main scale 2 indicates for measuring the digital calibration (2b, 2c) of length.
