When it is necessary to adjust the height of the placement plate 14, it is only necessary to rotate the screw rod 7. When the screw rod 7 rotates, it will drive the connecting plate 10 to move upward through the connecting block B16. When the connecting plate 10 moves, it will drive the connecting block A9 to move upward on the surface of the sliding rod 21, and will also drive the placement plate 14 to move upward. When it is necessary to store the placement plate 14, it is only necessary to slide the fixing block 15 out of the fixing hole 11. At this time, the placement plate 14 will be subjected to the torsion force of the torsion spring 13 to rotate the placement plate 14. At this time, the storage of the placement plate 14 can be completed. The connecting plate 10, the rotating rod 12, the torsion spring 13, the placement plate 14, and the fixing hole 11 The fixing block 15 makes it easy to adjust the height of the placement plate 14 and also makes it easy to store the placement plate 14, thereby avoiding the situation that the arm of the measurer cannot be placed flat due to environmental influences. When the measuring instrument needs to be carried, the dial block 22 only needs to be dialed downward, and the dial block 22 will drive the clamping block 23 and the slide bar 21 to move downward. At this time, after the cover plate 19 is inserted into the slide groove 18, the dial block 22 is released. At this time, the clamping block 23 will be clamped into the clamping groove 20 by the elastic force of the spring 25. After the clamping block 23 is clamped into the clamping groove 20, the closing of the cover plate 19 can be completed. At this time, the housing 1 can be carried by the handle 17. The slide bar 21, spring 25, handle 17, cover plate 19, clamping groove 20, clamping block 23, dial block 22 and slide groove 18 make it easy for medical staff to open and close the housing 1, and also make it easy to carry the measuring instrument.
