The utility mode relates to an appearance is drawn from calibrating device to direct reading pressure type railway spike, solved current railway spike draw appearance when calibration exist waste time and energy, inefficiency and receive the problem that the prescription influences. Counter -force support upper end is provided with opens the work platform who has the centre bore, the work platform top is fixed with the railway spike and draws the appearance body, the railway spike is drawn and is provided with the manometer on the appearance body, and the railway spike is drawn and is connected with the twin -feed spiral bolt that passes the centre bore on the pull rod of appearance body, be provided with the pressure sensor who is located the work platform below on the twin -feed spiral bolt, pressure sensor's lower extreme is provided with the lower nut of twisting on the twin -feed spiral bolt, the work platform upper end is provided with the top nut of twisting on the twin -feed spiral bolt, the last pressure display instrument that is connected with of pressure sensor. The utility model discloses can make things convenient for quick direct readout pressure, not restricted by calibrating period.
