The anti-slip pad 54 set on the clamping plate 53 is made of a soft material, and will be compressed to a certain extent when it contacts the expansion card 2, so that it fits the expansion card 2 more closely, and at the same time will not damage the expansion card 2, and then the expansion card 2 is fixed in a certain position, so that the stability of the expansion card 2 is better, and a better protection effect is achieved.
[0029] like Figure 2-Figure 4As shown, the plug-in mechanism 4 includes four springs 45, three square grooves 43 are provided on the front and rear sides of the inner wall of the expansion slot body 1, and two slide grooves 46 are provided on the left and right sides of the three square grooves 43.

[0030] It should be noted that, first, align the expansion card 2 with the expansion slot body 1, and at the same time align the limit slot 3 with the limit block 41, move the expansion card 2 downward, so that the expansion card 2 enters the expansion slot body 1, and at the same time, the limit slot 3 will move along the limit block 41. The limit slot 3 and the limit block 41 are set to be of the same size, so that the movement of the expansion card 2 is more stable, and at the same time, the expansion card 2 will be fixed, so that the expansion card 2 will not shake easily. During the movement of the expansion card 2, it will contact the roller 42, so that the roller 42 rotates, making the movement of the expansion card 2 smoother, and at the same time, the roller 42 will move outward, so that the slider 44 moves along the slide groove 46, so that the spring 45 is compressed. The set spring 45 has a certain elastic force, which will make the roller 42 fit on the expansion card 2, so as to achieve a better restriction effect, and thus achieve a better plug-in and unplug effect.
[0031] like Figure 2 , Figure 3 As shown, the length of the square groove 43 is slightly greater than the length of the roller 42 , and the depth and height of the square groove 43 are both greater than the outer surface diameter of the roller 42 .
[0032] It should be noted that the expansion card 2 contacts the roller 42 , causing the roller 42 to rotate, so that the expansion card 2 moves more smoothly.
[0033] like Figure 3 , Figure 4 As shown, the depth of the slide groove 46 is consistent with the thickness of the slider 44 , and the height of the slide groove 46 is consistent with the height of the slider 44 .
[0034] It should be noted that the slider 44 moves along the slide groove 46 , thereby causing the spring 45 to be compressed smoothly.
[0035] like Figure 1 , Figure 2 As shown, the expansion card 2 is provided with limit slots 3 at the left and right positions on the front and rear sides, and the expansion slot body 1 is fixedly connected with limit blocks 41 at the left and right positions on the front and rear sides of the inner wall. The width of the limit blocks 41 is consistent with the width of the limit slots 3.
[0036] It should be noted that the limit slot 3 will move along the limit block 41, and the limit slot 3 and the limit block 41 are of the same size, so that the movement of the expansion card 2 is more stable, and the expansion card 2 will be fixed at the same time, so that the expansion card 2 will not shake easily.
[0037] like Figure 5 , Figure 6 As shown, the protection mechanism 5 includes two connecting plates 51, the bottoms of the two connecting plates 51 are fixedly connected to the left and right positions of the top of the expansion slot body 1, the front ends of the two connecting plates 51 are rotatably connected to the rocker 52, the rear ends of the rocker 52 pass through the front ends of the connecting plates 51 and are fixedly connected to the bidirectional threaded rod 56, the front and rear positions of the bidirectional threaded rod 56 are threadedly connected to two limit sliders 57, and the two limit sliders 57 are fixedly connected to two clamping plates 53 at one end close to the expansion card 2.
[0038] The two locking cams 55 are in a state of being moved in a forward direction so that the locking cams 55 are ...
[0039] like Figure 5 As shown, the opposite surfaces of the two clamping plates 53 are fixedly connected with anti-skid pads 54, and the shape of the anti-skid pads 54 is an arc block.
[0040] It should be noted that the anti-skid pad 54 is made of a relatively soft material and will be compressed to a certain extent when it contacts the expansion card 2 , thereby fitting the expansion card 2 more closely and will not damage the expansion card 2 .
[0041] like Figure 5 , Figure 6 As shown, the opposite surfaces of the two connecting plates 51 are provided with limiting sliding grooves 55 , and the shapes of the limiting sliding grooves 55 and the limiting sliding blocks 57 are both T-shaped blocks.
[0042] It should be noted that the limiting slider 57 and the limiting slide groove 55 are both T-shaped blocks, which can prevent the limiting slider 57 from falling and also make the movement of the limiting slider 57 more stable.
[0043] The working principle of the utility model is as follows: first, align the expansion card 2 with the expansion slot body 1, and at the same time align the limit slot 3 with the limit block 41, move the expansion card 2 downward, so that the expansion card 2 enters the expansion slot body 1, and at the same time, the limit slot 3 will move along the limit block 41. The limit slot 3 and the limit block 41 are matched in size, so that the movement of the expansion card 2 is more stable, and at the same time, the expansion card 2 will be fixed, so that the expansion card 2 will not shake easily. During the movement of the expansion card 2, it will contact the roller 42, so that the roller 42 rotates, so that the movement of the expansion card 2 is smoother, and at the same time, the roller 42 will move outward, so that the slider 44 moves along the slide groove 46, so that the spring 45 is compressed. The spring 45 has a certain elastic force, which will make the roller 42 fit on the expansion card 2, so as to achieve a better restriction effect, so as to achieve a better plug-in and unplug effect, by rotating the rocker 52 clockwise, the roller The movable bidirectional threaded rod 56 rotates clockwise, and the bidirectional threaded rod 56 is set with the middle as the boundary, and the threads extend to both sides. Since the bidirectional threaded rod 56 is threadedly connected with the two limit sliders 57, the two limit sliders 57 are moved toward the middle along the limit slide groove 55. The set limit slider 57 and the limit slide groove 55 are both T-shaped blocks, which can prevent the limit slider 57 from falling, and also make the movement of the limit slider 57 more stable, thereby driving the two clamping plates 53 to move toward the middle, thereby making the two anti-skid pads 54 contact the expansion card 2. The set anti-skid pad 54 is made of a soft material. When it contacts the expansion card 2, it will be compressed to a certain extent, thereby more fitting the expansion card 2, and at the same time it will not damage the expansion card 2, thereby fixing the expansion card 2 in a certain position, making the expansion card 2 more stable and achieving a better protection effect. At the same time, the materials of all the components are insulating materials, which are not conductive, and achieve a better protection effect on the human body.
