[0025] During use, the operator first places the two components to be fixed between the two mounting rings 9 for fixing. Then, by rotating the turntable 12, the turntable 12 drives the rotating rod 13 fixedly connected to the outside to rotate inside the adjustment block 11. This action further drives the rotation of the gear 14, and the rotation of the gear 14 drives the movement of the rack plate 15. When the rack plate 15 moves, the adjustment column 10 will also move into the adjustment block 11. This series of actions eventually leads to the relative movement of the two mounting rings 9, and then the two fastening elements 23 contact each other and are fixed together, which makes it easy to dock and fix the two fastening elements 23, solves the problem that the existing fasteners can only fix a single element and cannot connect and fix two elements, improves the adaptability of the fasteners, and the two limit blocks 16 are slidably connected inside the limit groove 17, which plays a role of limiting. The mounting holes 2 are opened all around the inside of the bottom plate 1, which facilitates the fixing of the bottom plate 1.
[0026] Reference Figure 2 and Figure 3 The fixing assembly includes a screw rod 20, which is threadedly connected to both sides of the inside of the mounting ring 9, a hand wheel 19 is fixedly connected to the front side of the outside of the screw rod 20, and a clamping plate 21 is rotatably connected to the rear side of the outside of the screw rod 20. A protective pad 22 is provided on the inner wall of the clamping plate 21, and the protective pad 22 is made of rubber.
[0027] When it is necessary to fix fastening elements 23 of different sizes, first place the fastening elements 23 to be fixed in the middle of the mounting ring 9. Then, the operator turns the hand wheel 19, and the rotation of the hand wheel 19 drives the screw 20 to rotate. The rotation of the screw 20 further drives the movement of the clamping plate 21, and the movement of the clamping plate 21 drives the movement of the protective pad 22.

The gear 14 rotates and moves the rack plate 15 meshed on both sides of the outside. The rack plate 15 moves and moves the two sides of the outside fixed to the adjusting column 10 toward the inside of the adjusting block 11. When the two adjusting columns 10 move, the two mounting rings 9 fixed to the outside move relatively. The two mounting rings 9 move relatively and the two fastening elements 23 fixed to the inside move relatively, so that the two fastening elements 23 are in contact with each other, thereby achieving It is convenient to dock and fix the two fastening elements 23, which solves the problem that the existing fasteners can only fix a single element but cannot connect and fix the two elements, and improves the adaptability of the fastener. Then, when fixing fastening elements 23 of different sizes, the fastening element 23 to be fixed is placed in the middle of the mounting ring 9, and then the hand wheel 19 is rotated. The hand wheel 19 rotates with the screw rod 20 fixed to the outside, and the screw rod 20 rotates with the clamping plate 21 connected to the rear side of the outside rotation. The clamping plate 21 moves with the protective pad 22 set on the inner wall, and the protective pad 22 is fitted with the outside of the fastening element 23, so that the fastener is convenient for fastening fastening elements 23 of different sizes, and the practicality of the fastener is improved.
