[0020] In this embodiment of the application, when conducting circuit experiments, a fixing device can be used to fix different types of equipment components at any position on the experimental screen. The experimental screen displays simulated wires between different equipment components, and then simulated wires and real experimental equipment form an experimental circuit. This allows direct observation of the connection relationship and working status of the real experimental equipment, thereby improving the realism, vividness and efficiency of the circuit experiment, and reducing the complexity of experimental operations (such as connecting wires).

[0021] In one optional embodiment, the control unit includes an adsorber and a controller 220. The adsorber is connected to the fixed body 210 and the controller 220 respectively.

The controller 220 is equipped with a release button and an adsorption button. When the fixed device needs to be installed on the experimental screen, it must be placed at the target position on the screen with the opening of the fixed body 210 abutting against the screen. The adsorption button controls the action of the adsorber to create a negative pressure in the space between the fixed body 210 and the experimental screen, thus fixing the device to the screen.
