[0006] Furthermore, the first limiting device has the same structure as the second limiting device. The first limiting device includes two symmetrically arranged connecting blocks. Two springs are provided on the side of each connecting block that is close to each other, and clamps are provided on the side of each spring.

[0007] Furthermore, the clamping plate on the first limiting device and the second limiting device are movably connected to the connecting plate, the connecting block on the first limiting device is fixedly connected to the connecting plate, and the connecting block on the second limiting device is movably connected to the connecting plate.

[0008] Furthermore, the adjusting device includes a second threaded post, with movable blocks at both ends of the second threaded post. A circular groove runs through the side of each movable block, and a first annular threaded post is movably connected to one side of each circular groove. A second annular threaded post is movably connected to the side of each circular groove away from the first annular threaded post.

[0009] Furthermore, the second threaded post is movably connected inside the circular groove and the two are of the same size. The second threaded post is movably connected to the inner rings on the first and second annular threaded posts and the two are of the same size.

[0010] Furthermore, the fixed blocks are all located on the side of the connecting block on the same side of the first limiting device, and the movable block is fixed on the side of the connecting block on the same side of the second limiting device.

[0013] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:

[0014] 1. By adjusting the second threaded post, the first annular threaded post, and the second annular threaded post in the adjustment device, the distance between the second limiting device and the first limiting device can be precisely adjusted. Then, with the structural design of the spring and clamping plate on the first and second limiting devices, the side of the clamping plate that contacts the circuit board is made of soft material. While providing sufficient clamping force to fix the circuit board, it can effectively avoid damage to the surface of the circuit board. It can also flexibly adapt to circuit boards of different sizes. In this way, stable clamping can be achieved by adjusting the limiting device and the adjustment device, effectively preventing the circuit board from deforming or being damaged during storage.

[0015] 2. The first threaded post on the top of the base plate cooperates with the movable circular groove of the movable box. Combined with the use of the nut, the movable box can be easily stacked and fixed in multiple layers. This design saves storage space and facilitates the management and retrieval of circuit boards, improving the space utilization of the storage device. The bottom of the base plate is equipped with pulleys with a locking structure, which allows the storage device to be flexibly moved to different production stations according to the needs of the production process.

Movable circular grooves 13 are provided at the four corners of the movable boxes 2, and pulleys 14 are provided at the four corners of the base plate 1. The threaded posts, pulleys, and nuts in this invention are existing technologies and are not described in detail. The pulleys are pulleys with a locking structure.

[0025] The first limiting device 6 and the second limiting device 7 have the same structure. The first limiting device 6 includes two symmetrically arranged connecting blocks 61. Two springs 62 are provided on the side of the two connecting blocks 61 that are close to each other. Each spring 62 has a clamping plate 63 on its side. The side of the clamping plate 63 that is in contact with the circuit board is made of a soft material, such as rubber.

[0026] The clamping plates 63 on the first limiting device 6 and the second limiting device 7 are movably connected to the connecting plate 5. The connecting block 61 on the first limiting device 6 is fixedly connected to the connecting plate 5, and the connecting block 61 on the second limiting device 7 is movably connected to the connecting plate 5.

[0027] The adjusting device 9 includes a second threaded post 93, with movable blocks 91 at both ends of the second threaded post 93. A circular groove 92 passes through the side of each movable block 91. A first circular threaded post 94 is movably connected to one side of each circular groove 92. A second circular threaded post 95 is movably connected to the side of each circular groove 92 away from the first circular threaded post 94.

[0028] The second threaded post 93 is movably connected inside the circular groove 92 and the two are of the same size. The second threaded post 93 is movably connected to the inner rings of the first circular threaded post 94 and the second circular threaded post 95 and the two are of the same size. The inner rings of the first circular threaded post 94 and the second circular threaded post 95 are both threaded and are matched with the threads on the second threaded post 93.

[0029] The fixed blocks 8 are all located on the side of the connecting block 61 on the same side of the first limiting device 6, and the movable block 91 is fixed on the side of the connecting block 61 on the same side of the second limiting device 7. The fixed blocks 8 and the movable block 91 are located on the same side.

[0030] The second threaded post 93 is fixed between the two fixed blocks 8, and the connecting post 10 is fixed to the lower end of the side of the two connecting blocks 61 on the second limiting device 7.

[0032] Working Principle: In use, the second limiting device on the fixing device 4 inside the first movable box 2 is first adjusted. This adjustment is based on the circuit board dimensions. First, the first annular threaded post 94 on the side of the second limiting device 7 is rotated towards the side of the collecting groove 3. Through the cooperation of the second threaded post 93 with the fixing block 8 and the circular groove 92, the distance between the second limiting device 7 and the first limiting device 6 is brought closer, so that the fixing block 8 is located on the side of the first annular threaded post 94. Then, the second annular threaded post 95 is rotated, and through cooperation with the second threaded post 93, the second annular threaded post 95 is fixed to the side of the fixing block 8, thereby adjusting the position of the second limiting device 7. Once the circuit board is fixed, the clamping plates 63 on the first and second limiting devices are moved toward the connecting block 61. The circuit board is then placed between the clamping plates on the two limiting devices, which allows for the clamping and placement of circuit boards of different sizes. The movable circular groove 13 on the movable box 2 is then aligned with the first threaded post 11, and the first threaded post 11 is inserted into the movable circular groove 13, so that the movable box 2 is located at the bottom of the base plate 1. After storing the remaining circuit boards inside the movable box according to the above steps, the movable boxes 2 are stacked on top of the base plate 1. The movable boxes are then fixed by the cooperation of the nut 12 and the first threaded post 11, which facilitates subsequent transportation and storage.
