[0038] Working principle: When in use, the propaganda device consists of two parts: a propaganda device base 1 and an internal pull-out plate 14, wherein the propaganda poster 17 is fixed in the propaganda poster positioning groove 16 in the pull-out plate 14 by a magnetic buckle 18. Before the pull-out plate 14 is placed in the propaganda device base 1, the content of the propaganda poster 17 can be flexibly replaced according to needs. When placed, the pull-out plate 14 is inserted into the slide groove 13 in the propaganda device base 1 and pushed forward steadily until the limit plate 8 at the rear end of the pull-out plate 14 is completely inserted into the limit groove 7. At this time, the permanent magnet plate 15 at the end of the pull-out plate 14 is fixed to the inner wall of the electromagnet seat 4 by its own magnetic force, so that the installation and fixation of the pull-out plate 14 is realized. After installation, the pull-out plate 14 has no external force application point because the limit plate 8 at the end is completely inserted into the limit groove 7, and the stability is good. When the propaganda poster 17 needs to be replaced, a signal can be sent to the single-chip microcomputer chip in the control seat 5 by a remote terminal such as a mobile phone to drive the electromagnet The electromagnet 20 in the seat 4 runs, generating magnetism with the same polarity as the permanent magnet plate 15, relying on the magnetic repulsion to make the pull-out plate 14 pop outward, so that the propaganda poster 17 can be replaced conveniently and quickly. When the entire device is in use, the light intensity sensor 6 located on the side can detect the light intensity of the external environment in real time. When the light intensity is lower than the built-in threshold of the light intensity sensor 6, it will feedback a signal to the control seat 5, and the single-chip microcomputer chip in the control seat 5 will feedback a signal to the lamp bead board in the light bar seat 3 to control the lamp beads to light up and achieve the lighting effect. When the light intensity is higher than the built-in threshold of the light intensity sensor 6, it will feedback a signal to the control seat 5, and the single-chip microcomputer chip in the control seat 5 will feedback a signal to the lamp bead board in the light bar seat 3 to control the lamp beads to go out. The inner support tube 9 of the equipment support part can be stretched along the telescopic groove 21 in the outer support tube 10 to adjust the support height of the propaganda equipment base 1. After the adjustment is completed, the screw rod 23 can be locked by the nut 24 to fix it.
