a: the pointer of the dial indicator does not rotate, and the inclination of the inclined planes at the two sides of the tooth socket where the spring limiting shaft (25) is located is the same when the rotation positioning plate (21) does not rotate, and the inclination of the end face tooth is matched with the inclination of the shape of the machining cutter because the inclination of the shape of the machining cutter of the tooth socket is fixed, so that the inclination of the two sides of the end face tooth can be judged to be the same, namely the machining meets the requirements;
b: the pointer of the dial indicator rotates clockwise, which indicates that the rotating positioning plate (21) rotates clockwise, the inclination of the inclined planes at the two sides of the tooth socket where the spring limiting shaft (25) is located is greater on the clockwise side than on the anticlockwise side, the rotating scale of the pointer is qualified within the tolerance range, and the pointer is unqualified when the rotating scale exceeds the required tolerance;
c: the pointer of the dial indicator rotates anticlockwise, which shows that the rotating positioning plate (21) rotates anticlockwise, the inclination of the inclined planes on the two sides of the tooth socket where the spring limiting shaft (25) is located is larger than that on the anticlockwise side, the rotating scale of the pointer is qualified within the tolerance range, and the pointer is unqualified when the rotating scale exceeds the required tolerance.
