[0002] At present, mobile phones, computers and wearable electronic products have flooded into people's daily lives and become necessities of life. With the improvement of product testing requirements, the requirements of electronic testing on the test environment (shielding device) are also getting higher and higher, and the market demand for shielding devices is gradually increasing. However, the existing shielding devices are mostly replaced by simple bakelite boxes, micro-sized cast aluminum boxes or buckle-type shielding boxes. These shielding devices have simple manufacturing processes and single shielding box materials, such as:

[0003] Publication No. CN211090473U discloses a shielding box, which is provided with a first carrier jig and a second carrier jig, and a plurality of first threaded holes are provided on the first carrier jig, and a plurality of second threaded holes are provided on the second carrier jig, thereby ensuring that the first carrier jig and the second carrier jig can be disassembled and fixed, so that the shielding box can test a variety of different types of products;

[0004] However, the above device still has certain shortcomings when in use. First, multiple first threaded holes are opened on the first carrier jig of the electronic product, and multiple second threaded holes are opened on the second carrier jig, so as to ensure that the first carrier jig and the second carrier jig can be disassembled and fixed. When the electronic products are fixed by using two sets of carrier jigs, manual fixing and disassembly are often required. This process is relatively cumbersome and is not suitable for limiting the position of multiple groups of electronic products.

[0005] Therefore, we proposed a shielding box with an internal limit structure that can solve the above problems well. Utility Model Content

In addition, two sets of pull ropes are wrapped around the outside of the rotating shaft. The outer side of the connecting gear is meshingly connected to the fixed rack, and the connecting shaft is driven to rotate by the pull rope.

[0013] As a preferred technical solution of the present application, the bottom end of the fixed rack is fixed inside the shielding box body, and the two ends of the pull rope are respectively fixed at the ends of two sets of connecting shafts in different directions, ensuring that the connecting shafts can limit the electronic products placed on the top of the stage.
