A second limiting slot 45 is defined in the fastening member 40. The first limiting slot 45 has a larger end and a smaller end. The snap member 40 200925438 defines a υ-shaped groove at the edge of the snap end, and the bottom wall of the u-shaped groove forms an arc-shaped latch portion 46. The fixing member 60 includes a bottom wall 61, a trapezoidal first side wall 62 and a trapezoidal second side wall 63 extending vertically upward along the rear side and the side of the bottom wall 61. The bottom wall 61 has two limiting posts 612 protruding near the two ends. Each of the limiting posts 612 is provided with a τ-shaped limiting block 614. The limiting block 614 includes a large end at the upper portion and a small end at the lower portion. The bottom wall 61 defines two through holes 616 adjacent to the two limiting posts 612 and adjacent to the first side wall 62. The bottom wall 61 protrudes upward from the first side wall 62 to form two limiting plates 618. The first side wall 62 protrudes inwardly from a shaft 622. An elongated receiving groove 632 is defined in a middle portion of the second side wall 63. Each of the support members 70 includes a substantially rectangular substrate 7 from a central portion of the base plate 71 projecting upwardly from the cylindrical body 72, and the cylindrical body 72 is provided with a plurality of reinforcing ribs. The cylinder 72 defines a snap hole 722 in the direction of its axis. The cylinder 72 is circumferentially opened at its upper portion. The slot 726 is in communication with the aperture 722. A support post 73 is protruded from the support member 7 in the vicinity of the cylindrical body 72. The top end of the protrusion post 73 is provided with a butt-shaped limiting block 732. The limiting block 732 includes a large end at the upper end and a small end at the lower portion. . The substrate 71 also defines a fixing hole 78 and an elongated positioning hole 79. Referring to FIG. 4, one end of the elastic member 50 is placed in the receiving hole of the driving member 30, and the driving member 30 is placed in the fixing member 6〇, so that the operating portion 31 is self-contained. The second side wall 63 of the fixing member (10) is 200925438=the receiving groove (10) is pierced, and the other end of the elastic member 5Q is sleeved on the shaft 622 of the first side wall 62. Through the two screws (not shown), the two through holes 616 of the bottom wall 61 of the cymbal member 60 are respectively locked into the fixing holes 223 of the two protrusions 222 of the bottom plate 22, and the fixing member 6 is fixed thereto. The bottom plate 22 and the operating portion 31 of the driving member 3 are inserted into the bottom plate 224. The two support members 7 are respectively fixed on the bottom plate ·. · Each support member 70 is disposed on the corresponding position of the bottom plate 22 of the bottom plate 22, and the screw 4 is used. Passing through the fixing holes of the support member and locking into the fixing holes m of the corresponding fixing posts 226 of the bottom plate 22. The two fastening members 40 are respectively movably mounted on the corresponding sides of the fixing member 60 and the corresponding supporting members 7 并 and respectively located on two sides of the driving member. Taking the latching member 4〇 located on the right side of the driving member 3〇 as an example for description: the u-fastening member 40 is placed on the right side of the fixing member 6〇 and the support member on the right side of the fixing member 60 The limiting block 614 of the limiting column 612 and the limiting block 732 of the protruding column 73 are respectively engaged in the first limiting slot 43 and the second limiting position of the latching member 40. The large end of the groove 45 and the drive portion 35 on the right side of the drive member 30 are engaged in the oblique β groove 42 of the snap member 40. The latching member 40 is released, and the driving member 30 is moved outwardly by the elastic force. The driving portion 35 of the driving member 3 〇 slides in the inclined slot 42 of the latching member 40 to actuate the card. The fastener 40 moves away from the driving member 3〇, so that the limiting block/14 of the limiting post 6丨2 and the limiting block of the protruding post 73 are respectively engaged in the first fastening of the latching member. The small end of the limiting slot 43 and the second limiting slot 45, the latching end of the latching member 4〇11200925438 is engaged with the slot 726 of the supporting member 70. The two limiting plates 618 of the forming component 6G are respectively The two latching members 4 are lifted and locked. The cover plate 24 is closed with the bottom plate 22, so that the engaging holes 722 of the two supporting members 7〇 correspond to the two through holes 242 of the cover plate 24, respectively. Referring to FIG. 5, the cover body 1 is pivotally mounted on the base 2〇, and the cover body 1G is rotated to pass the two hooks 12 through the cover hole 242. The two hooks 12 are respectively The guiding portions 122 respectively enter the latching holes 722 of the two cylindrical bodies 72, and respectively press the latching portions 46 of the two latching members 4, so that the cover 10 continues to rotate, and the guiding of the two hooks 12 Part m respectively actuate the two snap members 40 toward Moving in the direction of the driving member 30, the two latching members 40 move the rearward movement of the driving members through the inclined sliding grooves 42 4 to compress the elastic members 50' until the guiding portions 122 of the two hooks 12 pass through respectively. The U-shaped groove of the two fastening members 40, at this time, the elastic member 5 is elastic: the gray driving member 3 is ejected forwardly, and the two driving portions 5 of the driving member 3 are respectively at the two fastening members The slanting chute 42 of the shank slides to move the two latching members 40 in a direction away from the driving member 3〇 until the latching portions 46 of the latching member 4 are respectively engaged with the latching slots 124 of the latching hooks 12 So that the two hooks 12 are respectively hooked to the two latching members 4, and the cover 10 is locked to the base 2, and the positional relationship is as shown in FIG. 6. When the cover body 1〇, the operation portion 3 of the driving member 30 is pressed inwardly, and the driving member 30 is moved backward against the elastic force of the elastic member 5〇. The two driving portions 35 of the driving member 30 are respectively at the two fastening members. The slide of the 4 inch slant/moon groove 42 drives the two fasteners 4 to move toward the drive member 12 200925438 until the cards of the two cards, such as the ^ 卞, 卞 fastener 4 () The portion 46 is respectively inserted into the card slot 124 of the two card fishing 12, p mountain, ia Α . 0Λ, and the king is opened, so that the cover 1 打开 can be opened relative to the base 20. Obviously, the two drives The cross section of the portion 35 may also be circular or, and it is easy for the slider 35 to be slidably slid into the shape of the movable body. The elastic member 50 may directly oscillate and the drive member 3〇. Between the temple 9 and the bottom plate 22 of the base 20, a baffle is protruded from the bottom to abut the elastic member 5〇. - The patent is in accordance with the invention patent, 爰According to the law: The above is only the preferred embodiment of the present invention. :佟:...
