When installing the collection frame 306, since the cross-section of the end of the card plate 402 is a trapezoidal structure, after the card frame 403 conflicts with the card plate 402, the card plate 402 will first drop until the through hole of the card frame 403 is above the card plate 402, the spring 406 resets, driving the card plate 402 to engage into the card frame 403, and then quickly fixes the collection frame 306.
