[0023] According to one embodiment of the present invention, the measuring point of the longitudinal measuring element 10 is located at the center of the second chuck 12.

[0024] Specifically, the horizontal direction where the transverse measuring component 5 is located can be recorded as the x-axis, the vertical direction where the longitudinal measuring component 10 is located can be recorded as the y-axis, and the vertical direction where the vertical measuring component 6 is located can be recorded as the z-axis. For example... Figure 1As shown, in order to measure the distance between the inlet and the outlet of the pump, the front cover measuring jig of the application is designed. The first chuck 4 is clamped at the inlet of the pump, and the second chuck 12 is moved to clamp at the outlet of the pump. Since the first chuck 4 is fixed, the inlet of the pump can be regarded as a reference. The plane where the first transverse beam 2 and the second transverse beam 3 are located is defined as the xoz plane, and the transverse distance between the outlet and the inlet can be measured by the transverse measuring piece 5. The vertical distance between the outlet plane and the inlet plane can be measured by the vertical measuring piece 6.
