The movement of the receiving plate can drive the moving rod to move, thereby driving the first protective plate to move horizontally, and then adjusting the length of the protective device. At this time, the protective net will extend and lengthen during the adjustment process. After the adjustment is completed, the second bidirectional threaded rod is rotated on the inner wall of the first protective plate by rotating the first handle, thereby driving the two groups of connecting blocks to move.

After completion, the card block is connected to the inner wall of the card slot, and the protrusion is released. At this time, the latch will reset due to a rebound force generated by the spring when the protrusion is pulled, and form a card connection with the slot hole. At the same time, the card block is further fixed by turning the screw to complete the installation. When disassembling, similarly, the card block can be released by turning the screw and pulling the protrusion to remove it. Through the setting of the device, the effect of convenient disassembly and installation is achieved, which greatly improves the practicality and convenience of the device.
