Thereby the whole system meets the requirements of line marking, calibration and measurement. The measuring part takes a magnetic grid ruler as a standard ruler, a maynuo-M8811 power supply supplies power to the product, and an upper computer directly controls the current and voltage output of the power supply. The analog quantity measurement is directly read and output by each path of magnetic rule independently connected with the Fluke-M8808A, and the measurement switching of the current and the voltage of the Fluke-M8808A is automatically switched by the upper computer according to the output set by the magnetic rule.

in the process that the moving mechanism 1 enters the protective shell 9, the moving mechanism 1 pushes the inclined surface of the second contact 16, so that the second contact 16 is contacted with the first contact 14 under the pushing of the moving mechanism 1, the electric guide rail 11 is started to drive the sliding rod 12 to move downwards, so that the sealing plate 10 is driven to seal the protective shell 9, in the process that the moving mechanism 1 moves towards the side far away from the protective shell 9, the moving mechanism 1 is not contacted with the second contact 16, at the moment, the spring can push the second contact 16 to be not contacted with the first contact 14 any more, and therefore the electric guide rail 11 drives the sealing plate 10 to move upwards, and then the moving mechanism 1 can normally move out of the protective shell 9, so that the function of automatically lifting the sealing plate 10 is achieved, and the effect of manually and fussy lifting of the sealing plate 10 is not needed; when the moving mechanism 1 enters the protecting shell 9, the moving mechanism 1 firstly extrudes the arc-shaped surface of the first elastic block 17, so that gas in the first elastic block 17 enters the hollow column 15 from the first connecting pipe 18 and the hollow rod 3, and then the gas is blown onto the moving mechanism 1 from the gas hole 13 formed in the hollow column 15, so that dust impurities on the moving mechanism 1 are blown out of the opening of the protecting shell 9 (at the moment, the sealing plate 10 is not dropped yet), parts on the moving mechanism 1 are not affected by the impurities, and the accuracy of a magnetic scale scribing, calibrating and measuring result of the magnetic scale is improved; when the bottom end of the sealing plate 10 contacts with the moving mechanism 1, the second elastic block 20 is extruded and deformed to be attached to the moving guide rail, so that the gap between the bottom end of the sealing plate 10 and the moving guide rail is reduced, and the sealing effect of the sealing plate 10 is improved; in the process that the moving mechanism 1 enters the protective shell 9, the moving mechanism 1 can extrude the hollow block 21, so that gas in the hollow block 21 enters the second elastic block 20 from the gas guide pipe 22, and the second elastic block 20 is expanded to be further attached to the moving guide rail, so that gaps between the bottom end of the sealing plate 10 and the moving guide rail are further reduced, and the sealing effect of the bottom end of the sealing plate 10 is improved; when the first elastic block 17 is extruded, the air in the first elastic block 17 is discharged from the first connecting pipe 18 and the second connecting pipe 23 respectively, at this time, the air discharged from the second connecting pipe 23 enters the guiding groove 24, and then the air pushes the driving groove 25 at the guiding groove 24, so that the driving groove 25 drives the hollow column 15 to rotate, the air hole 13 on the hollow column 15 can discharge air by means of the air discharged from the first connecting pipe 18, at this time, the air hole 13 can blow out the impurities on the moving mechanism 1 in all directions under the condition that the hollow column 15 rotates, the effect of blowing out the impurities on the moving mechanism 1 is improved, and meanwhile, a complex power source is not required to be arranged to drive the hollow column 15 to rotate.
