Abstract

The invention discloses a layer board power take-off device and a display stand. When the layer board and the display stand are assembled, the power take-off shell drives the power-taken electrode to move toward the power-taken electrode direction under the abutment of the display stand, until the power-take-off electrode and the display stand are in contact with each other. The power receiving electrodes are in contact with each other, and the position stabilizing component can adjust the position of the power taking electrodes at any time under the pressing of the power taking shell to ensure that the power taking electrodes and the power receiving electrodes are kept in contact. Therefore, regardless of whether the assembly between the laminate and the display stand is tight, the position-stabilizing part can ensure that the power-taking electrode and the power-receiving electrode remain in contact, and will not cause the power to take off after the laminate and the display stand have been used for too long and are not tightly assembled. The separation between the electrode and the electrified electrode ensures the stability of electrification.
