November 15th Shuttle Replacement Page [0014] [0016] [0017] The abutting member 80 is a stepped A cylinder includes a large end 82 and a small end 84. Referring to FIG. 6 together, the abutting member 80 and the elastic member 70 are sequentially placed into the stepped holes of the fixing member 50 during assembly. Attaching the latching member 60 to one side of the securing portion 56 of the fixing member 50, the two lugs 64 of the latching member 60 are respectively engaged in the two fastening portions 56 of the fixing member 50, and the bumps are 642 plays the role of auxiliary clamping. One end of the elastic member 70 is engaged with the large end 82 of the abutting member 80, and the other end of the elastic member 70 is abutted against the bottom wall 61 of the engaging member 60. The fixing member 50 is placed on the fixing post 225 of the bottom plate 22 and the positioning post 227, so that the positioning post 227 of the bottom plate 22 is inserted into the positioning hole 59 of the fixing member 50. The fixing member 50 is fixed to the bottom plate 22 by a screw (not shown) passing through the fixing hole 58 of the fixing member 5 into the fixing hole 226 of the fixing post 225 of the bottom plate 22. The height of the fixing post 225 should be such that the distance between the fixing member 50 and the bottom plate 22 is sufficient to accommodate the card engaging member 60. The fixing hole 223 and the fixing member 50 of the protruding post 222 of the bottom plate 22 are respectively locked by the two screws 90 through the first limiting slot 43 and the second limiting slot 45 of the locking member 4 respectively.

One of the pushers 30 abuts against the pushing surface 342 against the pushing end 41 of the latching member 40. The cover plate 24 is then covered with the bottom plate 22 such that the through hole 46 of the latching member 4 corresponds to the through hole 242 of the cover plate 24. Under the elastic force of the elastic member 7, the small end 84 of the abutting member 80 protrudes from the top of the cylinder 52 and penetrates into the through hole 242 of the cover plate 24 to fill the through hole 242, so that the Cover 24 096146786 Form No. A0101 Page 7 / Total 20 Page 1003419869-0 1375876 Surface Leveling 100 November 2007 IS [0018] [0020] [0021] Please refer to FIG. 7 together The cover body 1 is pivotally mounted on the base 2 , and the cover 10 is rotated. The guiding portion 122 of the hook 12 presses the abutting member 80 and passes through the through hole 46 of the latching member 40 . . The latching member 4 is repositioned by a spring (not shown), and the latching portion 473 of the latching member 4 passes through the cylindrical body 52 under the restoring force of the spring (not shown). The slot 526 is snapped into the slot 124 of the hook 12, so that the hook 12 is hooked to the latching member 40, and the cover 1 is locked to the base 2〇. When the cover 10 needs to be opened, the pusher 3 is pushed inwardly, and the driving portion 34 of the pusher 30 activates the pushing end 41 of the latching member 4 to move the latching member 40 away from the latching member 40 The pusher member 30 is moved in the direction of the pusher member until the latching portion 473 of the latching member 4 is completely withdrawn from the latching groove 124 of the hooking member 12, so that the cover member 10 can be opened relative to the base member 2. After being opened, the small end 84 of the abutting member 8 protrudes from the top of the cylindrical body 52 and penetrates into the through hole 242 of the cover plate 24 to fill the through hole 242 under the elastic force of the elastic member 7 Flat, so that the surface of the § 玄 cover 24 is flat. Obviously, as a second preferred embodiment of the buckle device of the present invention, the other end of the elastic member 70 can be directly engaged with the bottom plate 22, so that the card member 60 can be omitted. In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art will be included in the following claims.
