[Prior Art] Conventional computers often require data exchange with an external device, which is usually connected to an external device through an expansion card connected to a computer motherboard. The expansion card is installed in the slot of the computer motherboard. During the process of moving the computer or when the computer is accidentally impacted, the expansion card will loosely shake or even fall off, which may cause damage to the expansion card and the motherboard slot. In the prior art, the expansion card includes a board body connected to the motherboard and a file having an interface of the external device. The block is generally in an "L" shape. After the card is inserted into the slot of the motherboard, use the multiple screws to lock the bracket to the rear panel of the computer chassis, so as to securely fix the expansion card. However, such an expansion card retaining method must use a locking component such as a screw, which is cumbersome to wear and disassemble, and is time consuming and labor intensive. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide an expansion card fixing device which is simple in structure and convenient in operation. An expansion card fixing device for fixing an expansion card provided with a blocking piece to a rear plate of a chassis, the expansion card fixing device comprising a fixing member fixed to the rear plate and a pressing member slidingly connected with the fixing member The pressing member includes a stopping portion, a pressing portion, and a sliding portion. The fixing member includes a sliding slot and a positioning portion, and the sliding portion of the pressing member is slidably mounted in the sliding groove of the fixing member. Slide the pressure clamp to press the clamp part against the blank of the expansion card. The pressure form number is Α0101. Page 3/14 pages 0992076172-0 201225812 The stop of the card is stopped at the positioning part of the fixture. Compared with the prior art, the expansion card fixing device is simple in operation and convenient to operate by pressing the slide of the card member relative to the fixing member to press or unlock the expansion card. [Embodiment] [0007] Referring to FIG. 1 , a preferred embodiment of the expansion card fixing device of the present invention is used to fix a plurality of expansion cards 100 to a rear panel 2 of a computer case. The expansion card fixing device comprises at least one pressing member 30 and a fixing member 4''. One end of each expansion card 100 is provided with a substantially "L" shaped blocking piece 1 , which includes a connecting portion 12 connected to the expansion card 100 and a bent portion formed by the top of the connecting portion 1 2 The bent portion 14. The bent portion 14 is provided with a u-shaped groove 142. [〇〇〇9] The rear plate 20 is provided with a plurality of slots 201, and the rear plate 2 has a bridge-shaped limiting portion 204 protruding from each side of each slot. The rear plate 2 is bent over the slots 2〇1 to define a receiving portion 21, and then a mounting plate 23 is formed on the upper portion of the carrying portion 21. The bearing '2 + is protruded from the position between each of the two slots 201 to form a bump 212. 2, the crimping member 30 includes an elastic main body portion 31, a stopper portion 32 at the upper end of the main body portion 31, and an L-shaped end portion located at the lower end of the main body portion 31 and extending to the side of the main body portion 31. The pressing portion 33 and a handle 34 and a sliding portion 35 extending from the blocking portion 32 to the side of the main body portion 31 are formed. At least one connecting plate 36 is connected between the sliding portion 35 and the other side of the main body portion 31 for connection. The sliding portion 35 is substantially in the shape of a square sheet. [0011] Please refer to FIG. 3 together, the fixing member 40 includes a main body plate 41 and a plurality of parallel limit formed by one side extension of the main body plate 099144018 Form No. A0101 Page 4 / 14 pages 0992076172-0 201225812 41 Block 43, each of the limiting blocks 43 has a cross-section of a τ shape, and includes a sheet body 431 parallel to the main body plate ο and spaced apart by a distance, a connecting sheet body 431 and the main body panel 41, and the sheet body 431 and the main body panel The vertical connecting portion 433 and the positioning portion 435 projecting from the top end of the sheet body 431 in a direction away from the main body plate 41. A slipper 45 is formed between each of the two limit blocks 43. [0012] Referring to FIG. 4 and FIG. 5 together, at the time of assembly, the fixing member 40 is fixed to the mounting plate 23 of the rear plate 2 by screws or rivets (not shown). It can be understood that the fixing member 40 is plastic injection molded, and the fixing member 40 can also be fixed to the mounting plate 23 of the rear plate 2 by means of hot melt. The sliding portion 35 of the pressing member 3 is placed in the sliding groove 45 of the fixing member 40. [0013] When the expansion card 10 is installed, the expansion card is inserted into the slot of the circuit board (not shown), and the flap 1 of the expansion card 100 is placed at the slot 201 and the cymbal 1 is 〇 Bend. The crucible 14 is placed on the carrying portion 21. The limiting portion 2〇4 on both sides of the slot 2q 1 limits the connecting portion 12 of the expansion card 1〇〇, and the slot 142 of the (four) portion 14 catches the bump 212 on the carrying portion 21 to position the blocking piece 1〇 . The handle 34 of the pressing member 30 slides the sliding portion 35 of the pressing member 30 downward along the sliding groove 45 of the fixing member 4〇, and the blocking portion 32 of the pressing member 30 is locked to the positioning portion of the fixing member 4〇. When the lower portion is 435, the pressing portion 33 of the pressing member 30 presses the flap 10 of the expansion card 100, and the expansion card 1 is fixed. [0014] When the expansion card 1 is removed, the handle 34 of the pressing member 30 is pulled to elastically deform the main body portion 31 of the pressing member 30 away from the fixing member 40 to the stopping portion 32 of the repeating card member 30. The positioning portion 435 of the fixing member 40 is disengaged from the card, and the pressing member 30 is pulled upward to disengage the pressing portion 33 of the pressing member 3 from the blocking piece 10 of the expansion card 100, so that the expansion card 1 can be removed. 〇〇Removal 099144018 Form No. A0101 Page 5 of 14 Howl 2 201225812 [0015] In summary, the present invention meets the requirements of the invention patent, and patent application is filed according to law.
