During daily use, the electronic sign needs to be installed at a desired location. The existing installation process is complicated and increases the labor.

It is difficult to be affected by vibration or external interference, and needs to be improved. Utility Model Content

[0004] The utility model aims to provide an electronic sign that is easy to install. By means of the cooperation between the components such as the motor, the bidirectional screw rod and the threaded sleeve inside the installation and fixing device, it is achieved that the positive rotation of the motor drives the positive rotation of the bidirectional screw rod. The positive rotation of the bidirectional screw rod drives the two threaded sleeves to make relative movement. The relative movement of the two threaded sleeves drives the two clamping plates to make relative movement. The limit rod penetrates and is slidably connected to the side of the threaded sleeve. The limit rod is used to limit the movement trajectory of the threaded sleeve. When it needs to be installed at a certain place, the motor can be started to make the two clamping plates move relative to each other. The two clamping plates are clamped at a certain place, so that the electronic sign is fixedly installed at a certain place, providing a strong clamping force, which can ensure that the electronic sign is firmly fixed at the specified position and is not easily affected by vibration or external interference, thereby solving the existing problems.
