[0002] Tobacco is an annual herbaceous plant of the genus Nicotiana in the Solanaceae family. The leaves are oblong-lanceolate, lanceolate, oblong or ovate, with the apex gradually tapering and the base gradually narrowing into auricles that semi-embrace the stem. The petiole is not obvious or forms a wing shape; the inflorescence is paniculate, the calyx is tubular or tubular-campanulate, the lobes are triangular-lanceolate, the corolla is funnel-shaped, light yellow, light green, red or pink, with a yellow base; the capsule is ovoid or elliptical, nearly equal in length to the persistent calyx; the seeds are round or broadly oblong, brown; the flowering and fruiting periods are in summer and autumn.

[0003] However, during the existing tobacco leaf processing, when measuring the size of tobacco leaves, most need to be detected manually, which is easy to damage the tobacco leaves and has low efficiency in measuring the tobacco leaves; therefore, it does not meet the existing requirements, and for this reason, we propose a novel device for measuring the size of tobacco leaves.

[0013] 1. Through the lead screw and the moving block arranged on the inner side of the fixing frame of the present utility model, by using the lead screw transmission and the opposite helix directions at both ends of the lead screw, the moving block can move inwards and outwards simultaneously, which is convenient for the camera outside the positioning rod below the moving block to calibrate the tobacco leaves. Moreover, by using the pointer and the scale arranged at the upper end of the moving block, the measured length can be accurately observed, improving the detection accuracy of the device.

[0014] 2.
