New description: [New technical field] The creation system provides an improved design of the card connector's advance and retreat card device, especially an advancing and retracting device that can effectively prevent the memory card from being detached during the card withdrawal stroke. Improvement. [Prior Art] 'The conventional card connector is mainly composed of an insulating base body and a metal cover. The insulating body is composed of a plurality of terminal slots, terminals and detecting pieces, and is insulated. One side of the base body is provided with a set of advance and retreat card devices for controlling the insertion and positioning of the memory card and the ejection and withdrawal. The advancing and retracting card device generally comprises a slider, a spring, a brake lever and a hook card. When the memory card is inserted, the slider is used to push the compression spring (or the conventional one also uses the slider to expand the tension spring to achieve the same purpose), so that one end of the brake lever can be moved and positioned in the slider guiding groove. At this time, the elastic arm of the hook card has been locked into the card slot of the card. Therefore, the memory card is positioned after being inserted; but when the memory card I is to be withdrawn, the hook card arm starts to shift away from the memory card. The card slot, the slider under the force of the spring, will hit the memory card, it is easy to cause the card to bounce off and suddenly fly out (that is, the so-called flying card phenomenon), because today's memory cards are mostly light and short , so the bomb is off the fly The situation is more serious, not only is it quite troublesome to use, but it is also easy to cause the card to be lost or damaged. [New content] The main purpose of this creation is to provide an improved design of the card connector's advance and retreat card device, especially in the memory card's card withdrawal stroke, the hook 5 M320771 card arm can continue to hold the memory card. Therefore, it can effectively prevent the memory card from being released from the air. In order to achieve the above object, the present invention creates a limiting slot on the metal cover of the card connector, and the starting point of the limiting slot is a wide slot, and continues to extend inward to form a slotted slot. The hook card of the card and the ejecting device disposed at the relative position of the limiting slot is provided with an upwardly extending limiting tab, so that the limiting and the tab are embedded in the limiting slot, so that the limiting tab can follow the limiting slot Advance and retreat movement, especially in the retracting stroke, since the limit tab is gradually re-enclosed from the narrow and long position to the wide slot, it can ensure that the hook arm of the hook card does not shift, so that the hook card arm can be continuously hooked With the memory card, when the limit tab is returned to the wide slot, the spring of the card is retracted, so that the card can be effectively prevented from flying. [Embodiment] The structure and other functions and purposes of the present invention will be described in detail with reference to the accompanying drawings. > As shown in the first to fourth figures, the present invention is "improving the card connector's advance and retreat card device. The design mainly comprises: an insulating base body 1, a metal cover 2 and an advancing and retracting device 3, wherein: the insulating base body 1 is provided with a plurality of terminals 11, and the side of the seat body is accommodated with a set The embodiment of the insulative housing 1 can be implemented as a single card slot (as shown in the embodiment) or in a composite card slot for a single or various memories. The card 4 is inserted and used; the metal cover 2 is matched with the insulating base 1 and is opened at a selected position of the gold 6 M320771 cover 2 - the starting point of the limiting slot 21 is one a wide slot 211 and extending inward to form an elongated slot 212
