Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0016] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. This application discloses a fastener retaining device. (Refer to...) Figure 1 and Figure 6 A fastener holding device includes a fastener body 1, the fastener body 1 includes a fastening bolt 11, a fastening top cover 12 is fixedly connected to the top of the fastening bolt 11, the fastening bolt 11 and the fastening top cover 12 are integrally formed, a fastening nut 13 is threadedly connected to the surface of the fastening bolt 11, and an anti-rotation mechanism 2 is provided at the bottom of the fastening nut 13. The anti-rotation mechanism 2 includes a positioning ring 21, which is fitted onto the surface of the fastening bolt 11. A magnet 22 is fixedly connected to the top of the positioning ring 21. A circular groove 25 is formed inside the fastening nut 13, and the inside of the circular groove 25 engages with the surface of the magnet 22. The magnet 22 and the fastening nut 13 are magnetically connected. A slider 29 is fixedly connected inside the positioning ring 21. A vertical groove 14 is formed on the surface of the fastening bolt 11, and the surface of the vertical groove 14 is slidably connected to the inside of the slider 29. Through the vertical groove 14 formed on the surface of the fastening bolt 11, after the positioning ring 21 slides onto the surface of the fastening bolt 11, the slider 29 slides into the vertical groove 14, which can guide and limit the sliding position of the positioning ring 21. Furthermore, after the positioning ring 21 is connected to the fastening nut 13, it prevents the positioning ring 21 from rotating. After the magnet 22 is engaged in the circular groove 25, it is magnetically connected to the fastening nut 13, thus achieving the effect of connecting the positioning ring 21 and the fastening nut 13.

[0017] Reference Figure 2 and Figure 3The fastening nut 13 has slots 24 on both sides inside, and elastic blocks 23 are fixedly connected to both sides of the top of the positioning ring 21. The surface of the elastic blocks 23 engages with the inside of the slots 24. The slots 24 allow the elastic blocks 23 to be smoothly inserted into the fastening nut 13, further strengthening the connection between the fastening nut 13 and the positioning ring 21. The elastic blocks 23 are elastic and can be made of elastic sheets, so they can be smoothly inserted into the fastening nut 13. The elastic blocks 23 are also barbed, which further prevents the positioning ring 21 from easily falling off the surface of the fastening nut 13. Reference Figure 4 and Figure 6 The fastening bolt 11 has a through groove 15 inside, and a horizontal plate 28 is slidably connected inside the through groove 15. The horizontal plate 28 is fixed inside the positioning ring 21. The through groove 15 allows the horizontal plate 28 to slide smoothly into the fastening bolt 11. The through groove 15 is opened horizontally inside the fastening bolt 11, which can prevent the positioning ring 21 from rotating again after the horizontal plate 28 slides in. Reference Figure 3 The fastening bolt 11 has a positioning groove 26 inside, and a positioning post 27 is engaged inside the positioning groove 26. The bottom of the positioning post 27 is fixed to the top of the horizontal plate 28. The positioning groove 26 allows the positioning post 27 to be smoothly engaged inside the fastening bolt 11. After the positioning post 27 is inserted into the positioning groove 26, the stability of the connection between the fixing ring 21 and the fastening nut 13 can be increased. Reference Figure 2 The fastening top cover 12 has a slot 16 inside. The slot 16 is hexagonal. With the slot 16, the fastening top cover 12 can be rotated not only by external tools, but also by external workpieces driving the fastening top cover 12 to rotate, thus achieving a two-way function.

A lower support pad 3 is fitted on one side of the surface of the fastening bolt 11, and the bottom of the lower support pad 3 is in contact with the top of the fastening nut 13. By setting the upper support pad 4 and the lower support pad 3, the fit between the fastening top cover 12, the fastening nut 13 and the workpiece is improved respectively. At the same time, it can protect the workpiece and avoid damage to the workpiece due to excessive tightening force.

[0018] Working principle: First, the top cover 12 and the fastening bolt 11 pass through the two workpieces. The upper support pad 4 is placed between the top cover 12 and the upper workpiece, while the lower support pad 3 is placed between the fastening nut 13 and the lower workpiece. The fastening nut 13 is rotated, causing it to move downwards towards the lower workpiece due to the threaded connection between it and the fastening bolt 11, until the two workpieces are locked together. Then, the positioning ring 21 is slidably fitted onto the surface of the fastening bolt 11, and the positioning ring 21 drives the slider 2. 9 slides into the interior of the vertical groove 14, while the positioning ring 21 drives the horizontal plate 28 to slide into the interior of the through groove 15 until the positioning post 27 is engaged in the positioning groove 26. The movement of the positioning ring 21 will drive the magnet 22 to be engaged in the circular groove 25. With the magnetic connection between the magnet 22 and the fastening nut 13, the stability of the connection between the positioning ring 21 and the fastening nut 13 can be increased. The elastic block 23 is engaged in the slot 24. Under the action of various components, the fastening nut 13 is prevented from rotating.
