A hollow elastic member 8 is movably installed at the interval between the two first curling edges 3011. The middle part of the elastic member 8 passes through the fixing column 2, and the two ends of the elastic member 8 are respectively fixedly connected to the first support rod 801 and the second support rod 802. The first support rod 801 and the second support rod 802 are respectively located on both sides of the fixing column 2, and the first support rod 801 and the second support rod 802 extend in the direction away from the central axis of the fixing column 2 respectively.

A plurality of clamping grooves 9 are arranged at intervals in the height direction of the bracket 1. When the buckle 3 is passed through the fixing column 2, the second support rod 802 is clamped in the clamping groove 9.

[0032] like Figure 3 and Figure 5 As shown, the adjusting member 4 includes a second curling edge 402 fixedly connected to the adjusting end 6, the second curling edge 402 is integrally formed with the adjusting end 6, and is rolled inward along one side edge of the adjusting end 6 to form a second curling edge hole 403, the second curling edge hole 403 is rotatably sleeved on the fixing column 2, so that the adjusting member 4 is rotatably sleeved on the fixing column 2 through the second curling edge hole 403, and an adjusting plate 601 is fixedly connected to the adjusting end 6, the adjusting plate 601 is coaxial with the adjusting end 6 and is set at a preset angle, and at the same time, the adjusting end 6 is located on the side closest to the product 5 to be fixed compared to the movable end.

[0033] It should be noted that the preset angle between the adjustment end 6 and the adjustment piece 601 is set to 1°~120°, and the specific preset angle between the adjustment end 6 and the adjustment piece 601 includes but is not limited to 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110° or 120°.

[0034] Through the above-mentioned arrangement, before adjusting the snap member 3 through the adjusting member 4 to position the product 5 to be fixed, it is first necessary to insert the snap member 3 and the adjusting member 4 on the fixing column 2, specifically including: the fixing column 2 is removed from the bracket 1, and is inserted on the fixing column 2 along the curling hole of the snap member 3 through the bottom end of the fixing column 2, and the elastic member 8 is placed between the two first curling edges 3011, and the first curling hole 3012 is aligned with the middle through hole of the elastic member 8, so as to realize that the hollow elastic member 8 and the first curling edge 3011 are coaxially inserted on the fixing column 2; then the second curling hole 403 is adjusted to be inserted through the bottom end of the fixing column 2 to cover the fixing column 2, the adjusting piece 601 is rotated, and the adjusting end 6 is arranged on the side closer to the product 5 to be fixed than the movable end, and at the same time, the first support rod 801 on the elastic member 8 is adjusted to be clamped on the baffle body 301, and the second support rod 802 is adjusted to be clamped in the card slot 9, so as to realize the position installation of the snap member 3 and the adjusting member 4.

[0035] It should be noted that in this embodiment, the elastic member 8 is configured as a torsion spring. The setting of the elastic member 8 can provide the snap member 3 with an initial state elastic force, that is, the crimping piece 303 of the snap member 3 always maintains a movement tendency toward the side close to the accommodating space in the initial state, thereby enhancing the positioning effect of the snap member 3 on the product 5 to be fixed.

[0036] In this embodiment, Figure 5 As shown, the adjusting end 6 in the adjusting member 4 is in the shape of an elongated strip, and when the adjusting member 4 is installed on the fixing column 2, the length direction of the adjusting end 6 extends along the length direction of the fixing column 2, and the projection of the driving plate 302 on the plane where the central axis of the fixing column 2 is located partially or completely covers the projection of the adjusting end 6 along the plane where the central axis of the fixing column 2 is located, thereby ensuring that the adjustment range of the adjusting end 6 can cover the position of the driving plate 302, and ensuring the reliability of the adjustment process of the buckle 3 by the adjusting member 4.

[0037] like Figure 3 As shown, during the installation of the expansion card, the number of slots provided by the expansion card needs to be adjusted according to the number of PCIE boards, in order to provide more slots in this embodiment, multiple expansion cards need to be installed at the end of the bracket 1. In order to facilitate the simultaneous clamping and fixing of multiple expansion cards and improve the convenience of tool-free adjustment, when a number of fasteners 3 are sleeved along the length direction of the fixed column 2, the several fasteners 3 are successively penetrated and installed on the fixed column 2 along the length direction of the fixed column 2, and the projections of the drive plates 302 of the several fasteners 3 on the plane where the central axis of the fixed column 2 is located are partially or completely covered with the projections of the adjustment end 6 along the plane where the central axis of the fixed column 2 is located, so that when the adjustment end 6 rotates around the fixed column 2, multiple fasteners 3 can be adjusted at the same time to facilitate the crimping and positioning of multiple products 5 to be fixed.

[0038] Furthermore, in order to prevent the clip 3 inserted on the fixed column 2 from sliding during use, causing its position to deviate, a first protrusion 10 and a second protrusion 11 are fixedly connected to the side wall of the fixed column 2, wherein the cross section of the first protrusion 10 is an oblique right triangle. When the clip 3 is inserted along the fixed column 2 to a preset position, the first protrusion 10 is embedded between the first curling edge 3011 hole of the clip 3 and the fixed column 2, so as to realize the positioning of the installed clip 3 through the first protrusion 10, and multiple first protrusions 10 are provided along the length direction of the fixed column 2 to realize the stop of multiple clips 3. The second protrusion 11 has the same structure as the first protrusion 10. When the adjustment member 4 is inserted along the fixed column 2 to a preset position, the second protrusion 11 is embedded between the second curling edge 402 hole of the adjustment member 4 and the fixed column 2, so as to realize the positioning of the installed adjustment member 4 through the second protrusion 11.

[0039] like Figure 3 As shown, the fixing column 2 in this embodiment is disassembled and installed at one end of the bracket 1 through a connecting piece. Specifically, the top end of the fixing column 2 is fixedly connected to the mounting column 12. The mounting column 12 is a stepped column, and its diameter is larger than the column body part of the fixing column 2. The bracket 1 is provided with a mounting hole 13 corresponding to the mounting column 12. The mounting column 12 is penetrated into the mounting hole 13 to realize that the top end of the fixing column 2 and the bracket 1 are fixed to the bracket 1 by riveting with protrusions.

[0040] Furthermore, a stop block 14 is installed at the bottom end of the fixed column 2, wherein the stop block 14 in this embodiment is configured as a stop plastic buckle, and a blind hole is opened at the top of the stop block 14. When the fastener 3 and the adjustment member 4 are installed, the upper blind hole of the stop block 14 is adjusted to be plugged into the corresponding bottom end of the fixed column 2 to achieve the stop block 14 being sleeved on the bottom end of the fixed column 2. At the same time, a stop hole 15 is opened on the side wall of the stop block 14, and a corresponding fixing hole is set on the bracket 1. The stop hole 15 and the fixing hole are penetrated by a connecting member to achieve the connection between the bottom end of the fixed column 2 and the bracket 1.

[0041] It should be noted that the stop hole 15 on the stop block 14 is configured as a screw hole or a pin hole, the fixing hole on the bracket 1 is configured as a salad hole, and the connecting parts include but are not limited to countersunk screws, screws, pins or I-nail.

[0042] In a specific embodiment, in order to ensure that the product 5 to be fixed on the bracket 1 is located within the accommodating space and to improve the overall stability of the product 5 to be fixed, a limiting hole 502 is provided on the product 5 to be fixed, and two limiting holes 502 are symmetrically provided at both ends of the product 5 to be fixed. A limiting member 16 corresponding to the limiting hole 502 is provided on the bracket 1. In this embodiment, the limiting member 16 is an I-shaped nail, and two I-shaped nails are symmetrically provided on the side wall of the bracket 1, respectively corresponding to the limiting holes 502 on the product 5 to be fixed. The limiting holes 502 are adjusted to be installed correspondingly on the limiting member 16 so that the product 5 to be fixed is placed within the accommodating space.

[0043] like Figure 6 , Figure 7 and Figure 8 As shown, since several expansion cards usually need to be installed on the side wall of the bracket 1 to provide more slots for the PCIE board, that is, it is necessary to install multiple layers of expansion cards in the height direction of the side wall of the bracket 1, further, the limiting hole 502 is set as a gourd-shaped hole or a strip hole, and a slide is set on the bracket 1, that is, each layer of expansion card corresponds to a slide, the slide is L-shaped, and the L-shaped slide support is connected to the bottom side wall of the product 5 to be fixed, and the slide is set at the lower part of the limiting member 16. When it is necessary to insert the limiting hole 502 on the product 5 to be fixed into the limiting member 16 on the bracket 1, the bottom side wall of the product 5 to be fixed is adjusted to fit with the slide, and the product 5 to be fixed is adjusted to slide in the direction close to the fixing column 2, so that the product 5 to be fixed moves into the accommodating space, and finally the positioning block 7 on the buckle 3 is driven by the adjusting member 4 to be inserted into the positioning hole 501 to realize the positioning of the product 5 to be fixed.

[0044] It should be noted that in this embodiment, a first label is set on the driving piece 302 and a second label is set on the adjusting piece 601 , wherein the content of the second label is set to “ALL” to indicate that the adjusting piece 601 can simultaneously realize unlocking and fixing of multiple fasteners 3 .

[0045] Specific implementation process: confirm the corresponding number of fasteners 3 according to the number of products 5 to be fixed, match the first curling edge 3011 hole of the fastener 3 with the bottom end of the fixing column 2, place the elastic member 8 between the two first curling edges 3011, and align the middle hole of the elastic member 8 with the first curling edge 3011 hole, adjust the fastener 3 from the bottom end of the fixing column 2 to pass through the fixing column 2, when the first curling edge 3011 is engaged with the first protrusion 10 on the fixing column 2, at this time, the fastener 3 is passed to the preset position, adjust the first support rod 801 of the elastic member 8 to be connected to the baffle body 301, adjust the second support rod 802 of the elastic member 8 to correspond to the card slot 9 to complete the installation of a fastener 3, and similarly, The fastener 3 is passed through the fixing column 2; the second curling hole 403 in the adjusting member 4 is matched with the fixing column 2, and the adjusting member 4 is passed through the fixing column 2 along the bottom of the fixing column 2, and the adjusting end 6 is adjusted to slide along the fixing column 2 until the second curling hole 403 is engaged with the second protrusion 11. At this time, the adjusting member 4 is passed through the preset position to ensure that the adjusting end 6 is located closer to the side of the product 5 to be fixed than the movable end of the fastener 3; after the fastener 3 and the adjusting member 4 are installed, the top end of the fixing column 2 is installed on the bracket 1, and the stop block 14 is installed at the bottom end of the fixing column 2, and the stop hole 15 on the stop block 14 is adjusted to correspond to the fixing hole on the bracket 1, and the connecting member passes through the stop hole 15 and the fixing hole to realize the connection between the bottom end of the fixing column 2 and the bracket 1.

[0046] Then, according to the corresponding directions of the limiting hole 502 on the product 5 to be fixed and the limiting member 16, the product 5 to be fixed is inserted into the side wall of the bracket 1. Due to the setting of the limiting hole 502, the product 5 to be fixed can slide along the slide at this time, and the product 5 to be fixed is adjusted to move in the direction close to the buckle 3 until it moves into the accommodating space. At this time, the rotating adjustment end 6 is rotated in the direction away from the product 5 to be fixed, that is, it is rotated in the clockwise direction from the top perspective of the fixing column 2. The adjusting end 6 drives the driving plate 302 to rotate in the clockwise direction to open the crimping plate 303, and continue to push the product 5 to be fixed to move into the accommodating space until the positioning block 7 on the crimping plate 303 is stuck in the positioning hole 501, thereby realizing the installation and fixation of the product 5 to be fixed.

[0047] The tool-free fixing device in this embodiment can significantly improve production and operation efficiency.
