electromagnet 68 and the auxiliary electromagnet 74 is cut off, the magnetism of the main electromagnet and the auxiliary electromagnet is lost, the device recovers to an initial state under the action of the springs, and after testing is finished, an experimenter can judge the compressive strength of each experimental object through the linear distribution of the paper tape 67 wound on the collecting paper tape wheel 15.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
