Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1 to 4, a blade for plant experiments comprises a main blade body 4, a blade housing 2 is arranged on the outer surface of the upper end of the main blade body 4, protection mechanisms 1 are arranged at both ends of the main blade body 4, and a comparison mechanism 3 is arranged in the middle of the blade housing 2.

Further, the comparison mechanism 3 comprises an electrodeless sleeve 31, a scale shaft 32 and an anti-falling cap 33, the electrodeless sleeve 31 is arranged in the middle of the comparison mechanism 3, the scale shaft 32 is arranged in the electrodeless sleeve 31, and the anti-falling caps 33 are arranged on the outer surfaces of the two ends of the scale shaft 32.

Further, protection machanism 1 includes collet 11, fixed turn-button 12 and even axle 13, and the middle part of protection machanism 1 is provided with even axle 13, and the lower extreme surface of even axle 13 is provided with collet 11, and the upper end surface of even axle 13 is provided with fixed turn-button 12.
