However, the prior art cannot perform integral quantity tracing, and only the standard force measuring instrument 11 of the device can be disassembled into discrete pieces, which is very likely to cause an additional measurement error due to inconsistency with an actual stress state caused by only adopting a local component method for verification, so that uncertainty exists in the quantity tracing of the device, and therefore, the second embodiment is further defined as follows on the basis of the first embodiment:

The flange 131 is slidably connected to the drawer 51, and the locking screw 52 is locked to the measurement instrument module 1 when the drawer 51 slides to the protruding shoulder 132, so that the interference between the verification tool 5 and the workbench 13 is equal to the interference between the bottom surface of the measurement instrument 100 and the workbench 13 of the measurement instrument module 1, and thus the verification calibration with the same force value transmission state is performed on the verification tool 5 by simulating the contact between the workbench 13 of the measurement instrument module 1 and the bottom surface of the measurement instrument 100.

Therefore, when the force standard machine is used for carrying out magnitude traceability on the device, the verification tool 5 is installed in the workbench 13 of the measuring instrument module 1, the two are slid in through the drawer type guide rail 51 and positioned to the limit position by the aid of the arranged boss shoulder 132, the two are tightly fixed into an integral module by the aid of the locking screw 52, the integral module is placed on the verification working face of the force standard machine in an inverted mode, the ball feeding pressure head of the force standard machine is aligned with the customized nut pressure head 142 of the measuring instrument module 1, a standard force value can be applied, the integral verification accuracy and reliability of force value transmission are achieved in a bearing state closest to the same contact face, and therefore the force standard machine can be used for achieving the whole magnitude traceability on the premise that the force standard machine is not detached as a bulk part, extra measurement errors caused by adoption of component method verification are eliminated, and some uncertainties in magnitude traceability of the device are avoided.

After the embodiment is applied to industrialization, very good economic and social benefits are brought: firstly, the calibrating device can be provided for detection companies and metering technical mechanisms to use, and provides strong and reliable technical support for calibrating and calibrating the detector 100; secondly, product performance test evaluation can be provided for the detector 100 manufacturer, and powerful technical support is provided for the qualification rate control of products of the manufacturer; thirdly, the operation behavior is effectively guided and standardized, the scientific and reasonable traceability of the detector 100 is ensured, and the verification and calibration requirements of the technical index requirements of the national relevant technical specifications are met.
