The present invention compared with prior art, has the following advantages and advantages：
1st, when movable block is moved in position-limiting drum, mobile BOB(beginning of block) is compressed the present invention to spring, and movable block
For up big and down small truncated conical shape, multiple projections are fixed with the outer wall of movable block, while are offered in position-limiting drum multiple
The groove being engaged with projection, i.e. movable block continue to move down under the guiding of groove, effectively prevent the scale in measurement process
Sidesway occurs in fixed cylinder for chi, that is, prevents the internal diameter size of the non-pipeline of data that graduated scale is measured but higher in pipeline
The size in footpath；When the straight line where the axis and pipe diameter of fixed cylinder coincides, the data on graduated scale, the data are read
The displacement of linear motion generation is done for movable block, by calculating, i.e. the air line distance of steel ball bottom and ball top subtracts movement
The straight-line displacement that block occurs can draw the size of internal diameter of the pipeline；
2nd, the present invention is placed on rear, it is necessary to carry out certain regulation to ball and steel ball to protect in inner-walls of duct in fixed cylinder
Card device is overall to be kept overlapping with the diameter of pipeline, therefore graduated scale reading difficulty increases after adjustment, and the present invention is in movable block
Down-pressed pole is equipped between fixed seat, graduated scale is rotatably arranged on down-pressed pole, can directly be rotated in reading graduated scale with
Ensure its good observation visual angle, the quick progress being convenient for measuring；
3rd, the present invention is provided with the groove being engaged with projection, and circle of the internal diameter of position-limiting drum along ball on position-limiting drum inwall
The direction that the heart points to the steel ball center of circle is successively decreased, i.e., after movable block moves down a certain distance, projection can not continue to move in groove,
And then excessively moving down and cause graduated scale stress deformation for movable block is effectively prevent, ensure the accuracy of measurement data.
