The frame body 21 is more evenly divided and can be easily detached. 9 M428465 The first interface card 101 and the second interface card 1〇2 are inserted together with the frame 21 to be assembled on the motherboard! 2, and when the pull ring 23 is not used, the pull ring 23 can be spaced apart from the bottom wall U1 by a substantially parallel direction by engaging the pull ring 23 in the slot 15 of the cover 143. The upper starting position, and the space between the tab 23 and the bottom wall 111 is preferably such that a finger can be inserted into the user, and k is required for the user to detach the frame 21 through the pull ring 23. At this time, the hand is stretched between the pull ring 23 and the bottom wall 111 and the pull ring 23 is pushed upward to push out the card slot 15, and then it can be used. Therefore, the above-mentioned configuration of the pull ring 23, with the structure of the first notch 245 or the second notch 254, facilitates the user to force the frame 2 i to be detached from the main board 12, and the present invention can be achieved. For the purpose, and because the pull ring 23 is clamped on the second end portion 212 of the frame body 21, the first notch 245 and the second notch 254 are adjacent to the first end portion 211, when the user applies the force to the pull ring 23 respectively. When the first notch 245 or the second notch 254 is used, the frame 21 can be detached evenly with a relatively even force. When the card slot 15 is disposed, the tab 23 is conveniently positioned and in a convenient starting position. It is to be noted that, in this embodiment, the arrangement relationship between the components in the casing n is formed by forming the card slot 15 in the casing 143 ′ of the adjacent heat dissipation module 14 so that the frame body 21 is inserted and assembled. In the case of the motherboard 12, the frame body 21 is interposed between the card slot 15 and the end wall 112, so that the card slot 15 provides the pull tab 23 to be engaged and positioned in the vicinity. However, in other variations, the position of the card slot 15 is also formed. It can vary depending on the components that are adjacent. However, the above is only the preferred embodiment of the present invention, and the scope of the novel implementation cannot be limited by this, that is, the simple equivalent of the scope and the new description of the new patent application 10 M428465 Changes and modifications are covered by this new patent.
