storage box 44 step by step at last can make storage box 44 press compression spring 39C and telescopic link 41 shrink downwards, the pressure sensor body 4 that the output end receives the pressure will send out the signal and demonstrate the reading on the display screen 34 synchronously at this moment, can judge whether new pressure sensor body 4 has the measurement deviation through the gravity parameter cooperation of the weight and the reading that the pressure sensor body 4 on the display screen 34 transmits, the design through this structure has made things convenient for staff to the measurement experiment work of new pressure sensor body 4 greatly, and make the experiment can be expanded without obstacle whenever and wherever, not only has improved the control of pressure sensor body 4 accuracy, also very big reinforcing this device's flexibility, therefore, the clothes hanger is strong in practicability, in addition, the staff can be in advance with baffle 30 along articulated shaft 29's direction commentaries on classics board groove 27 after expanding this device, the arm-tie 26 that has lost baffle 30 holding power just can slide down along board groove 27 and make the bottom surface and the 1 bottom surface parallel and level of box body of pillar 24, the staff is let out baffle 30 again immediately, baffle 30 can change the normal position back and produce the restriction effect to arm-tie 26 top surface under torque spring 31's resilience effect, so 24 bottom surfaces of pillar can regard as the bearing structure of lid 2, avoid pillar 24 to rise upwards under the reaction force on ground, made things convenient for the staff to the expansion and the placing of this device, the convenience of use of this device has been strengthened greatly.
