2. Description of the Prior Art
Please refer to FIG. 12. FIG. 12 is a diagram of a circuit board 60 and a housing 62 in prior art. The circuit board 60 is an expansion card which can be installed inside the computer apparatus to increase operational efficiency. The computer apparatus may have a plurality of circuit boards 60 according to actual demand. A conventional assembling method utilizes a fixing component 64 (such as the screw or the bolt) to fix the circuit board 60 on a boss 66 of the housing 62, and a cover (not shown in figure) can press over the circuit board 60 to ensure the circuit board 60 is stably disposed inside the housing 62. However, the conventional assembling method is inconveniently executed because an extra tool is essential for assembly/disassembly of the circuit board 60. The extra tool can be a screwdriver applied to the fixing component 64. Thread structures of the fixing component 64 may be damaged after repeated operation, so the conventional assembling method has a drawback of inferior assembly strength.

DETAILED DESCRIPTION
Please refer to FIG. 1. FIG. 1 is an exploded diagram of an electronic device 10 according to a first embodiment of the present disclosure. The electronic device 10 includes a base 12, a connector 14 and a quick releasing mechanism 16. The connector 14 is disposed on the base 12. The base 12 can be utilized to hold an interface card 18, and the interface card 18 levelly inserts into the connector 14. The quick releasing mechanism 16 is disposed on the base 12 to fix position of the interface card 18, so that the interface card 18 can be stably assembled with the connector 14 and not be separated accidentally. Therefore, the electronic device 10 of the present disclosure has quick releasing function for the interface card 18. The user can manually assemble and/or disassemble the interface card 18 without auxiliary of extra tools.
The quick releasing mechanism 16 of the first embodiment includes a part of the base 12, a first constraining component 20 and a second constraining component 22. The first constraining component 20 is movably disposed on the base 12, and can be shifted between a releasing position and a constraining position. The second constraining component 22 is disposed on another side of the first constraining component 20, and movably disposed on the base 12 to shift between a disassembling position and an assembling position. The first constraining component 20 includes a sliding portion 24, a supporting portion 26 and a buckling portion 28. The sliding portion 24 is slidably disposed on the base 12, the supporting portion 26 is disposed on the sliding portion 24, and the buckling portion 28 is connected to the supporting portion 26. While the interface card 18 is put on the first constraining component 20, the supporting portion 26 supports a first surface 181 (the bottom) of the interface card 18, and the buckling portion 28 presses over a second surface 182 (the top opposite to the foresaid bottom) of the interface card 18, so as to constrain a movement of the interface card 18 at Z-axis. In addition, the buckling portion 28 may optionally include a protrusion 30 which pierces through an opening 183 formed on the interface card 18 to constrain a movement of the interface card 18 at X-axis and Y-axis, so that the interface card 18 cannot move by constraint of the supporting portion 26 of the first constraining component 20.
The quick releasing mechanism 16 further includes a positioning component 32 which is locked on a locking hole 68 formed on the base 12. The sliding portion 24 includes a slot structure 34, the sliding portion 24 is slidably disposed on the positioning component 32 via the slot structure 34, and the sliding portion 24 can move between the releasing position and the constraining position by assembly of the slot structure 34 and the positioning component 32. The sliding portion 24 further includes at least one contacting unit 36 disposed on an inner wall 341 of the slot structure 34, as shown in FIG. 2. While the sliding portion 24 moves relative to the positioning component 32, the contacting unit 36 can contact against the positioning component 32 to constrain a relative movement between the slot structure 34 and the positioning component 32, and the first constraining component 20 can be adjusted to stay at the releasing position or the constraining position according to user's demand.
Please refer to FIG. 2. FIG. 2 is an exploded diagram of the quick releasing mechanism 16 in another view according to the first embodiment of the present disclosure.

Generally, the present disclosure forms two slide chutes 38 arranged on the base 12 in parallel, and two guiding portions 40 of the first constraining component 20 respectively insert into the corresponding slide chute 38 in a slidable manner. Slide assembly of the slide chute 38 and the guiding portion 40 can prevent the first constraining component 20 from aslant rotation while moving relative to the base 12, so as to provide preferred assembly precision.
The second constraining component 22 includes a main body 42 and an engaging portion 44 connected to each other. The main body 42 can optionally include the slot structure 34 and/or the contacting unit 36, which have structures the same as the slot structure 34 and the contacting unit 36 of the sliding portion 24. The base 12 includes the positioning component 32 accordingly, so the main body 42 can be slidably disposed on the base 12 and shifted between the disassembling position and the assembling position. While the main body 42 moves to the assembling position, a lateral side of the interface card 18 is buckled by the engaging portion 44 to constrain the movement of the interface card 18 at Y-axis and X-axis.
Please refer to FIG. 3 to FIG. 5. FIG. 3 to FIG. 5 respectively are diagrams of the electronic device 10 indifferent operation modes according to the first embodiment of the present disclosure.
