Therefore, during the placement process, the bottom of the tube cover 100 is attracted to the table top due to the magnetic force of the magnetic member 3, and the occurrence of reverse buckling is prevented. Meanwhile, after the tube cover 100 is placed on the table top, the tube cover is not easy to be knocked over due to the adsorption formed by the magnetic force of the magnetic part 3. It should be understood that in a laboratory or a laboratory, most of the work benches are made of metal materials, and thus the tube cover 100 can be easily attached to the work benches by magnetic force. The magnetic member 3 and the cap insert 2 may be assembled separately, or the magnetic member 3 and the cap insert 2 may be integrally configured, for example, the cap insert 2 is directly prepared from a magnetic material.
