[0002] Plant leaves are important organs for photosynthesis, transpiration and gas exchange, and their morphology is diverse and significantly affected by plant species and environmental factors. When crops are subjected to drought stress, salt stress and other adverse environments, leaf curling often occurs, making it extremely difficult to accurately measure leaf length and width. Traditional measurement methods cannot accurately obtain true length and width data when measuring curled leaves, resulting in large measurement errors and affecting the accuracy of related research and analysis results based on leaf size data.

[0003] In particular, during the growth and development of wheat, the flag leaf is of great importance. The flag leaf is the topmost leaf of the wheat plant, and its growth status is closely related to the yield and quality of wheat. Flag leaf length and width are key indicators for evaluating flag leaf morphology and play a crucial role in assessing wheat growth. However, even high-precision plant leaf measuring scales, such as handheld live leaf area meters, photographic leaf area meters, and digital combined leaf measuring tools, struggle to accurately measure very irregular leaves or leaves with complex textures and wrinkles. In existing technology, irregular leaves can be measured from multiple angles, and the data can be analyzed to obtain more accurate leaf parameters. However, when faced with different shapes of leaves, the process is tedious and prone to errors due to the need for splicing measurements.

[0033] Specifically, rotate knob 3, drive threaded rod 4 connected with it to rotate, since limit block one 5 and limit block two 9 limit the rotating position of threaded rod 4, cause screw block 6 connected with threaded rod 4 to move on threaded rod 4, screw block 6 moves scale two 8 by fixed rod 7, and then adjust the position of scale two 8 relative to scale one 1, realize the function of accurately measuring lengthier plant leaf, the outside of scale one 1 is provided with multiple scale lines 10 at equal intervals, to measure plant leaf, the front and back sides of the left end of the bottom of scale one 1 are both provided with clamping groove 11, so that scale one 1 can be more conveniently taken.

[0034] With reference to Figure 1 , Figure 2 and Figure 5 , clamping mechanism 2 includes fixed plate 201, fixed plate 201 is arranged at the top of scale two 8, the top of fixed plate 201 is fixedly connected with clamping block one 202, torsion spring 203 is installed in the inside of clamping block one 202, and the function of compression rebound is played, the other end of torsion spring 203 is provided with clamping block two 204, the outside of clamping block two 204 is fixedly connected with pressing plate 205, the outside of pressing plate 205 is provided with rubber pad 206, the outside of knob 3 is provided with rubber ring 12, the outside of rubber ring 12 is connected with screw 13, and rubber ring 12 is fixed by screw 13, can better operate knob 3.

[0035] Specifically, when the operator applies pressure to the pressing plate 205, since the clamping block two 204 is installed on the pressing plate 205, and the torsion spring 203 is arranged on the clamping block two 204, this will cause the torsion spring 203 to produce torsional deformation and store corresponding elastic potential energy, and once the external force is removed, the torsion spring 203 will release its stored elastic potential energy, thereby driving the clamping block two 204 to rotate in the opposite direction, prompting the pressing plate 205 to return to the original position. The presence of the rubber pad 206 can increase the friction between the pressing plate 205 and the contacted object and play a buffering role, thereby realizing more stable clamping of the leaf for accurate measurement. The outer side of the knob 3 is provided with a rubber ring 12, and the outer side of the rubber ring 12 is connected with the screw 13 through threads. Through the fixing effect of the screw 13, the rubber ring 12 can improve the operation convenience of the knob 3.

[0037] Specifically, the outer wall left side of the scale one 1 is provided with a fixedly connected placing block 14, and the outer side of the placing block 14 is provided with a fixedly connected handle 15, so as to better operate.

[0038] Working principle: rotate the knob 3 to drive the threaded rod 4 connected thereto to rotate, since the limiting block one 5 and the limiting block two 9 limit the rotating position of the threaded rod 4, the threaded block 6 screw-connected with the threaded rod 4 moves on the threaded rod 4, and the threaded block 6 drives the scale two 8 to move through the fixed rod 7, so as to adjust the position of the scale two 8 relative to the scale one 1, realizing accurate measurement of the plant leaf with longer length.

[0039] When the operator presses the pressing plate 205, the clamping block two 204 is arranged on the pressing plate 205, and the torsion spring 203 is arranged on the clamping block two 204, so that the torsion spring 203 is deformed in torsion and stores elastic potential energy. When the external force is removed, the torsion spring 203 releases the elastic potential energy and drives the clamping block two 204 to rotate in the opposite direction, so that the pressing plate 205 is reset. The rubber pad 206 can increase the friction between the pressing plate 205 and the contacted object and play a buffering role, so as to more stably clamp the leaf and better measure.
