According to the principle of thread self-locking, the movable plate 8 is positioned. Under the elastic action of the spring 6, the spacing between the first baffle 7 and the second baffle 9 is adjusted. Therefore, the lower layer placement space is used to place circuit boards of uniform size, and the upper layer placement space can be adaptively adjusted according to circuit boards of different sizes. The spring 6 applies a downward pressure to the movable plate 5, so that the circuit board is stably placed between the first baffle 7 and the second baffle 9;
