The side surface of the threaded rod is screw-mounted with a threaded sleeve. The outer surface of the threaded sleeve is fixedly installed with three connecting rods.

[0009] One of the connecting rods corresponds to one of the activity slots, and one end of the connecting rod in the length direction is fixedly installed with a pressing plate mechanism. The pressing plate mechanism is arranged outside the three advertising boards.

[0010] Further, the pressing plate mechanism comprises a fixed ring arranged outside the three advertising boards. One end surface of the fixed ring close to the advertising board is provided with a pressing block. The pressing block and the fixed ring are fixedly installed with a spring. The outside of the spring is provided with a sliding sleeve.

[0011] Further, the sliding sleeve is fixedly connected with the pressing block, and the sliding sleeve is slidingly connected with the fixed ring.

[0012] Furthermore, three pressing plates are provided on opposite sides of the top plate and the bottom plate, a baffle is slidably installed inside one of the pressing plates, the baffle is fixedly connected to the advertising board, and an anti-slip sheet is fixedly installed on the side of the pressing plate close to the advertising board.

[0013] Furthermore, the baffle close to the bottom plate is provided with a threaded knob on one end surface close to the bottom plate, the threaded knob is rotatably connected to the advertising board, the threaded knob is threadedly connected to the pressure plate, and the baffle close to the top plate is provided with the same arrangement.

[0014] Furthermore, a second driving motor is fixedly installed inside the base, a connecting rod is fixedly installed on the output end of the second driving motor, and the connecting rod is rotatably installed on the upper part of the base and fixedly connected to the bottom plate.

[0015] Furthermore, a drive motor is fixedly mounted on one end of the threaded rod in the length direction, and the drive motor is fixedly mounted on the upper end surface of the top plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The utility model fixes the upper end of the advertising paper first, and then passes the advertising paper between the pressing block and the advertising board. The threaded sleeve drives the connecting rod to move toward the bottom plate, so that the fixing ring drives the pressing block to move. Under the action of the spring, the pressing block can smooth the advertising paper and fix the lower end of the smoothed advertising paper, so that the advertising paper can be easily replaced.
