Fixing structure of pressure transmitter detection and calibration tool and calibration tool

The utility model relates to a fixing structure of a pressure transmitter detection and calibration tool and the calibration tool. The fixing structure is mainly used for calibration and detection in the production process of a pressure transmitter. The utility model comprises: a mounting plate; the first clamping block is arranged on the mounting plate; the second clamping block is arranged on the mounting plate and can move relative to the first clamping block so as to clamp and fix the pressure transmitter to be measured; and the limiting column is arranged on the mounting plate, is arranged opposite to the first clamping block and is used for being matched with the first clamping block so as to realize temporary positioning of the to-be-tested pressure transmitter before the first clamping block and the second clamping block are matched to clamp the to-be-tested pressure transmitter. Compared with a connection mode through a threaded adapter in the prior art, the pressure transmitter pressure gauge not on
