The invention provides a circuit numerical simulation experiment device. The device can easily flip the testing table panel up and down. Real-time positioning and self-locking during up-down flip canbe achieved, which makes the flip process safe. The testing table panel will not suddenly flipped over on a large scale due to operating errors, which makes it safe and reliable. The invention can flip the test table panel left and right so that students standing on the left and right sides can conveniently observe the experiment table panel. The up-down flip and the left-right flip can be realized by one operating handle and the operation is convenient. The device integrates the functions of transverse flip and up-down flip on an operating rod, so that the teacher is convenient to operate when the test table panel is adjusted. Real-time positioning and self-locking can be achieved during up-down flip and there is no sudden flip due to losing the force, which guarantees the safety of the testing process.
