[0009] Preferably, the surfaces of the first caliper, the second caliper and the extended caliper are all provided with scale lines to facilitate accurate measurement, making the intelligent algorithm for taking pictures more accurate.

[0010] Preferably, the sliders are symmetrically arranged in two groups, wherein the sliders in one group are fixedly connected to the movable column, and the sliders in the other group are fixedly connected to one side of the movable rod, which is convenient for use and storage and can restore the use position.

[0011] Preferably, the movable column and the fixed column are of the same size, which improves measurement accuracy and facilitates measurement of wrinkled objects.

[0012] Preferably, one end of the insertion rod passes through the moving rod and extends into the first caliper, and the insertion rod and one end of the first caliper are movably inserted into each other, thereby improving the stability of the fixing of the moving rod and the insertion rod.

[0013] Preferably, the springs are symmetrically arranged in two groups, and the top ends of the two groups of springs are fixedly connected to the top ends of the inner walls of the first caliper and the second caliper respectively.
