As shown in fig. 1-3, the positioning bolt runner 1-1 allows the positioning bolt 3 to slide on the caliper 1 to measure distances of different pitches; reading out the standard value of the hole spacing of the standard component through the length value scale 1-2;
As shown in fig. 4, the locking nut is connected with the thread 2-1 of the positioning bolt 3, when the positioning bolt 3 is on the standard hole site, in order to avoid that the positioning bolt 3 continues to move on the caliper 1 to influence the reading, the locking bolt 2 is required to lock the positioning bolt 3 on the caliper 1;
As shown in fig. 5 and 6, the standard component hole positioning needle 3-1 adopts a conical design in order that the standard component hole positioning needle can position standard component holes with different apertures; the chute fixing rod 3-2 is used for keeping the pointer 4 parallel to the length value scale 1-2 at the moment when the positioning bolt 3 slides on the caliper 1, so that the rotation of the positioning bolt 3 can not be caused, and the pointer 4 is driven to rotate to influence the reading;
As shown in fig. 7, the pointer mounting hole 4-1 allows the pointer 4 to be mounted on the chute fixing rod 3-2 without rotating to affect the reading; the distance displayed by the corresponding length scale pointed by the two needle points 4-2 is the hole spacing value.
