The connector 20 of the expansion card 2 may be, but is not limited to, a card edge connector (golden finger), and is generally provided with second terminals in rows, and the side walls in the slot 41 are correspondingly provided with first terminals in rows so as to be coupled with the second terminals. The circuit board 4 is typically a motherboard, but the invention is not limited thereto. The surface shapes of the first side 23 and the second side 24 of the expansion card 2 include one of a plane or a substantially plane (e.g., a circuit board surface of the expansion card 2, a plane surface of an electronic component, a plane surface of a motor component (e.g., a plane surface of a heat sink), etc.), a bevel (e.g., a bevel surface of a motor component), and a curved surface (e.g., a curved surface of a motor component).

As shown in fig. 1 and 3, it can be defined that: the direction in which the expansion card 2 is inserted into the slot 41 is defined as a first direction D1, the extending direction of the connector 20 (for example, the arrangement direction of the plurality of second terminals, or the length direction of the slot 41) is defined as a second direction D2, and a normal vector of a plane formed by the first direction D1 and the second direction D2 (for example, the width direction of the slot 41) is defined as a third direction D3.

In detail, at least a portion of the expansion card 2 is disposed in a disposition space 30 defined by the fixed structure 3. For example, the fixing structure 3 is any one of the following: one of the frame 31, the housing 32, or a combination of the frame 31 and the housing 32 provides a stable support for each holder in the multi-axis adjustable holding system 1 for expansion cards, thereby stably holding the expansion card 2. In general, the circuit board 4 is also disposed on the fixing structure 3, and the slot 41 is disposed in the disposition space 30, and the housing 32 is disposed outside the chassis 31 with respect to the disposition space 30.

As shown in fig. 3, the first holder 11 includes a first holding portion 110 and a first adjusting portion 111. The first adjusting portion 111 is configured to adjust a position of the first adjusting portion 111 disposed on the fixing structure 3, and the first fixing portion 110 fixes the front end 21 when the first adjusting portion 111 is disposed on the fixing structure 3. In a possible embodiment, the first adjusting portion 111 is configured to adjust the position of the first adjusting portion 111 disposed on the fixed structure 3 in a fourth direction D4. The fourth direction D4 and the second direction D2 are parallel or form an acute angle therebetween, so that a thrust component of the first fixing portion 110 parallel to the second direction D2 is obtained by one of the adjustment directions of the plurality of first adjustment portions 111, and the expansion card 2 is abutted against the slot 41 in the second direction D2. Wherein, a turning angle is formed between the extending direction of the first holding portion 110 and the extending direction of the first adjusting portion 111. Further, the fourth direction D4 is parallel to the second direction D2, and the turning angle is a right angle.

In another possible embodiment, as shown in fig. 3, the first holding portion 110 includes a first slot 1100, so that a locking member 5 can adjust the position of the front end 21 held by the first holding portion 110 through the first slot 1100. In detail, taking the first slot 1100 as an example, two ends of the first slot 1100 have a semicircular perforation, and a rectangular perforation is formed between the two ends of the first slot and is communicated with the semicircular perforation, the length direction of the first slot 1100 (or the rectangular perforation) is parallel to or forms an acute angle with the first direction D1. However, the first slot 1100 may be a rectangular hole, a polygonal hole having a maximum length direction, or an oblong hole. The locking member 5 adjusts the relative position of the locking member 5 to the front end 21 and/or a bracket (breet) provided at the front end 21 along the length direction of the first slot 1100 through the first slot 1100. That is, the height component of one of the adjustment directions of the plurality of first slots 1100 in the parallel first direction D1 is adapted to the height (first direction D1) of the expansion card 2. Further, the length direction of the first slot 1100 is parallel to the first direction D1.

Similarly, the first adjusting portion 111 includes a second slot 1110 for a locking member 5 to adjust the position of the first adjusting portion 111 disposed on the fixing structure 3 through the second slot 1110. Wherein the shape of the second slot 1110 is similar to the shape of the first slot 1100. Thus, the locking member 5 adjusts the position of the locking member 5 locked to the fixing structure 3 along the length direction of the second slot 1110 through the second slot 1110. That is, the length component of one of the adjustment directions of the plurality of second slots 1110 in the parallel second direction D2 is adapted to the length of the expansion card 2 (second direction D2). Further, the length direction of the second slot 1110 is parallel to the second direction D2.

In a possible embodiment, as shown in fig. 4, the fixing structure 3 further includes a bridge plate 33, which includes a first opening 330 communicating with two opposite surfaces of the bridge plate 33, and the top 22 is located between the first opening 330 and the slot 41, so that the second holding unit 120 presses against the top 22 through the first opening 330. The bridge plate 33 is provided to the fixed structure 3 such as the frame 31. In this example, two opposite sides of the bridge plate 33 are disposed on two frames of the rack 31 on two opposite sides of the expansion card 2, such that the top 22 is located between the slot 41 and the first opening 330, so that the second holding unit 120 presses the top 22 through the first opening 330.

Further, the length direction (eighth direction D8) of the third slot 12110 is parallel to the second direction D2.

Further, referring to fig. 4 and 5, fig. 5 is a schematic cross-sectional view along line AA' of fig. 4. The second holding unit 120 is a box body with an opening or a U-shaped structure, two opposite ends of the bottom surface 1201 of the second holding unit 120 are respectively connected to two side surfaces 1202 of the second holding unit 120, and each of the two side surfaces 1202 includes a through hole 1203. The shape of the fourth slot 12111 is similar to that of the first slot 1100, so that the locking member 5 can adjust the position of the locking member 5 locked to the through hole 1203 along the length direction (the fifth direction D5) of the fourth slot 12111 through the fourth slot 12111. The fifth direction D5 is parallel or at an acute angle to the first direction D1. So that the height component of the parallel first direction D1 by one of the adjustment directions of the plurality of fourth slots 12111 is adapted to the height of the expansion card 2 (first direction D1). That is, the position where the bottom surface 1201 presses against the top 22 is adjusted to accommodate various possibilities that the top 22 is positioned at different heights (first direction D1) after being inserted into the slot 41. Further, the length direction (fifth direction D5) of the fourth slot 12111 is parallel to the first direction D1.

Further, the first buffer unit 6 is disposed on the bottom surface 1201, so that the top portion 22 is prevented from being damaged by the first buffer unit 6 when the bottom surface 1201 is pressed against the top portion 22.

In one possible embodiment, as shown in fig. 6 and 7, fig. 7 is a schematic cross-sectional view along line BB' of fig. 6. The bridge plate 33 further comprises two fifth slots 331 communicating with two opposite plate surfaces of the bridge plate. The third holding portion 130 and the fourth holding portion 140 respectively pass through a fifth slot 331, such that the first side 23 and the second side 24 are located between the third holding portion 130 and the fourth holding portion 140, for adjusting the distance between the third holding portion 130 and the first side 23 and the distance between the fourth holding portion 140 and the second side 24. The third adjusting portion 131 and the fourth adjusting portion 141 each further include a sixth slot 1310 for adjusting the positions of the first side 23 and the second side 24 of the third holding portion 130 and the fourth holding portion 140 by a locking member 5 through the two sixth slots 1310. The locking member 5 is locked to the bridge plate 33 through two sixth slots 1310. It should be noted that the positions of the third holder 13 and the fourth holder 14 are interchangeable.

In detail, the third holding portion 130 is connected to the third adjusting portion 131 by a turning portion, and the fourth holding portion 140 is connected to the fourth adjusting portion 141 by another turning portion.

The fifth slot 331 is rectangular or similar to the first slot 1100 in shape, and the sixth direction D6 is parallel or at an acute angle to the third direction D3. Thus, the width component of the third holding portion 130 and the fourth holding portion 140 in the third direction D3 parallel to one of the adjustment directions of the sixth slots 1310 is adapted to the width (the third direction D3) and/or the side profile of the expansion card 2. Further, the sixth direction D6 is parallel to the third direction D3.

As shown in fig. 6 and referring to fig. 7, the third adjusting portion 131 and the fourth adjusting portion 141 are overlapped with each other, and the sixth slot 1310 of the two is also at least partially overlapped, and the shape of the sixth slot 1310 is similar to that of the first slot 1100, so that the locking member 5 can be locked to the bridge plate 33 through the two sixth slots 1310 and the through holes or slots of the bridge plate 33.

Optionally, the multi-axis adjustable holding system 1 for expansion cards of the present invention further comprises at least one second buffer unit 7.
