The invention has the beneficial effects that:

one is as follows: the U-shaped plate at the end part of the external plug-in card body is inserted into the inner wall of the clamping groove, meanwhile, a rubber pad I on the inner wall of the U-shaped plate is contacted with the inner wall of the clamping groove, the T-shaped rod is loosened, an internal sliding frame at the end part of the internal sliding frame drives the internal sliding frame to reset through self elasticity, a main support frame I and a main support frame II move to reset simultaneously, two micro spring tee joints drive the main support frame I and the main support frame II to rotate through self elasticity, at the moment, an installation hole at the end part of the external plug-in card body is positioned outside two middle connecting rods and is blocked by outer baffle plates at two sides and the main support frame I, the external plug-in card body is fixed, the installation frame is positioned at a narrow part of a computer case, when a traditional user fixes the external plug-in card body by using a screw driver to control, the screw driver can be limited by space, so that the phenomenon that part of the screw driver can be installed at an oblique angle can be generated, meanwhile, the screw is small, the screw drops into the computer case and is difficult to find, which causes great inconvenience in installation, this device replaces the screw through utilizing the circular pipe, need not extra instrument installation, and the operation is swift convenient, improves the installation effectiveness.

The second step is as follows: the T-shaped rod moves to drive the connecting disc to move, the connecting disc moves to drive the inner sliding frame to move, the inner sliding frame moves to drive the micro-springs to stretch, the inner sliding frame moves to drive the main support frame I and the main support frame II to move, the main support frame I and the main support frame II are blocked by the two sponge cushions when moving, at the moment, the main support frame I and the main support frame II are forced to approach each other, the main support frame I and the main support frame II both rotate in the micro-springs through the rotating shaft, the main support frame I and the main support frame II approach each other and drive the two micro-springs to compress and deform, the device drives the main support frame I and the main support frame II to approach each other by pulling the T-shaped rod, so that the outer inserting card body can freely move outside the circular tube, a user can conveniently align the outer inserting card body with the clamping groove, and drives the main support frame I and the main support frame II to reset by the micro-springs, thereby the operation is not required by manpower, the main support frame I and the main support frame II automatically fix the outer card inserting body, so that the operation steps of a user are reduced, and convenience is further brought to the installation of an operator.

And thirdly: two side slide bars all slide in the interior slide rail that circular pipe was seted up, the cooperation of side slide bar and interior slide rail prevents effectively that interior slide frame from taking place rotatoryly when removing, stability when improving interior slide frame and removing, two outer baffles can be close to each other when rotatory, two outer baffles are close to each other and can drive two lower connecting rods and are close to each other, two lower connecting rods are close to each other and can drive two gag lever posts and be close to each other, the rectangular channel that slide including two gag lever posts were all seted up to the balladeur train, seting up of rectangular channel effectively prevents down that the connecting rod takes place the card when rotatory to pause, simultaneously lower connecting rod is the arc, consequently, the connecting rod can not contact the inner wall of circular pipe when rotatory, effectively prevent the jam.

Fourthly, the method comprises the following steps: two outer baffles can drive two lower connecting rods to rotate, the two lower connecting rods can drive two limiting rods to rotate, and the limiting rods are L-shaped, so that when the two limiting rods rotate to a certain angle, the horizontal sections of the limiting rods can be clamped with the inner wall of the circular tube, the two limiting rods can prevent the first main support frame and the second main support frame from continuously rotating, and therefore the first main support frame and the second main support frame are effectively prevented from rotating excessively, and the first main support frame and the second main support frame are prevented from rotating and falling.

And fifthly: the user extrudees main support frame one and main support frame two with two fingers, main support frame one and main support frame two atress are rotatory into in the circular pipe, two outer baffle atress are close to each other, when the distance between two outer baffles is less than the mounting hole, the user can outwards stimulate outer inserting card body, outer inserting card body dismantlement this moment finishes, press main support frame one and main support frame two pairs of outer inserting card bodies through utilizing the atress and dismantle, and is simple swift, also need not with the help of any instrument, the convenience of dismantlement has been improved greatly.

And the sixth step: the fixed plate of display card is connected with the outer plug-in card body with same mode and circular duct, the installation is accomplished the back, the below of display card fixed plate can contact with the rubber block, because the bracing piece is installed to the below of rubber block, fixed mounting has miniature spring one between the lower tip of bracing piece and the supporting shoe, consequently miniature spring drives the rubber block through self elasticity for a while and supports the fixed plate of display card, traditional display card weight is great, the phenomenon that descends can appear in the display card after the installation, the support of rubber block this moment effectively prevents to solve the phenomenon that the display card descends, effectively improve the stability after the display card installation.

And the seventh step: when inserting the card body in two through the mounting hole cover outside the connecting rod, the rubber ring of outer baffle, main tributary frame one and side ring board side tip all with the both sides contact of inserting the card body in, three rubber ring carries out the centre gripping to inserting the card body in, and three rubber ring plays better laminating effect, effectively prevents to insert the card body in two and takes place to rock outward, has further improved the fixed stability of inserting the card body.
