Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 3, the utility model comprises a blade 1, on blade 1, be equipped with a left ruler frame 2 and a right ruler frame 3, left and right chi frame 2,3 tops are respectively arranged with the trip bolt 4,5 that can lock blade 1, left and right chi frame 2,3 be respectively arranged with on one vernier 6 and vernier 7 once up and down, the last vernier 6 of left ruler frame 2 can not be provided with scale mark.Left ruler frame 2 is arc, and left ruler frame 2 bottoms are a L shaped measuring claw 8, and right ruler frame 3 is a shape, and two ends, the left and right sides, right ruler frame 3 bottom are respectively a craspedodrome measuring claw 9,10.
As Fig. 4, shown in Figure 5, the left and right chi frame of the utility model 2,3 fronts are horizontally arranged with a groove 11,12 respectively, a reed (not shown) is fixed at groove 11,12 tops respectively, corresponding with it, be respectively arranged with a threaded hole 13,14 at left and right chi frame 2,3 tops, screw 4,5 is spun on respectively in the threaded hole 13,14, withstands reed by its end blade is locked.
As shown in Figure 3, the utility model chi 1 body is upper and lower to be respectively arranged with one group of scale mark, and the zero-bit of two groups of scale marks is separately positioned on blade 1 two ends, and two groups of scale mark order reverse symmetry distribute.
The utility model measuring claw 8,9,10 left and right sides are measurement face, and measuring claw about 8 two is measured interplanar distance and determined according to the length of left ruler frame 2.The right side of measuring claw 9 is measured the left side measurement interplanar distance of face and measuring claw 10 and is determined by the maximum limit of size of circle navel diameter of phi 1.
The utility model may further comprise the steps when measuring:
