[0028] Referring to Figures 1 - 5 and Figure 8 As shown, it includes a screw body 5. The screw body 5 includes a head 501. The lower end of the head 501 is fixedly connected to a screw rod 502. The outer surface of the head 501 is fixedly connected with three evenly distributed first clamping blocks 7. The first clamping blocks 7 are clamped inside the first clamping groove 6. The lower end of the first clamping block 7 is fixedly connected to a rubber block 19. The outer surface of the screw rod 502 is threadedly connected with a fixed ring 10 through thread. The upper end of the fixed ring 10 is provided with a third fixing hole 1001. The outer side of the fixed ring 10 is fixedly connected with three equally spaced second clamping blocks 11. The outer surface of the screw rod 502 is movably connected with a steering wheel body 1. The lower end of the steering wheel body 1 is movably connected with a rotating column 2.

[0029] Furthermore, the lower end of the steering wheel body 1 is closely attached to the upper end of the rotating column 2. The upper end of the steering wheel body 1 is provided with a first fixing hole 3 which is wider at the top and narrower at the bottom. The upper end of the rotating column 2 is provided with a second fixing hole 4. The first fixing hole 3 is movably connected with a screw body 5 inside. The outer side of the upper end of the steering wheel body 1 near the first fixing hole 3 is provided with three evenly distributed first clamping grooves 6.

[0030] Furthermore, one end of the screw rod 502 away from the head 501 is movably inserted into the first fixing hole 3 and extends into the second fixing hole 4 and is threadedly connected in the second fixing hole 4 through thread.

[0031] Furthermore, the upper end of the rotating column 2 is provided with a first installation groove 8 outside the second fixing hole 4. The upper end of the rotating column 2 is provided with three equally spaced second clamping grooves 9 outside the first installation groove 8. The fixed ring 10 is inserted into the first installation groove 8, and the second clamping blocks 11 are clamped inside the second clamping grooves 9.

[0032] Furthermore, during the installation process, the first clamping block 7 ensures the correct alignment of the screw body 5 and the steering wheel body 1. At the same time, it can enhance the connection stability between the head 501 of the screw body 5 and the steering wheel body 1, reduce the problems of screw loosening or connection failure caused by vibration, and thus improve the reliability and durability of the overall connection.

[0033] Furthermore, the rubber block 19 can reduce the impact force generated on the steering wheel body 1 during the riveting process, thereby reducing the damage to the steering wheel body 1.

[0034] Furthermore, the second clamping block 11 and the fixing ring 10 can enhance the connection stability between the rotating column 2 and the screw rod 502. Through the clamping connection between the second clamping block 11 and the second clamping groove 9, the problem of loosening or instability of the connection between the screw rod 502 and the rotating column 2 caused by vibration or other external forces can be effectively reduced, which helps to improve the overall durability and reliability.

[0035] Furthermore, the diameters of the second fixing hole 4 and the third fixing hole 1001 are the same, and the diameter of the screw rod 502 is equal to the diameter of the first fixing hole 3 and greater than the diameter of the second fixing hole 4.

[0036] Furthermore, the diameter of the screw rod 502 is greater than the diameters of the second fixing hole 4 and the third fixing hole 1001, and is equal to the diameter of the first fixing hole 3. This design enables the screw rod 502 to be freely inserted into the first fixing hole 3 and form a fastening in the second fixing hole 4 and the third fixing hole 1001, ensuring that the screw body 5 can be firmly connected to the rotating column 2 after riveting.

[0037] Refer to Figure 5 and Figure 6 As shown, a groove 12 is provided on the outer surface of the screw rod 502 near the upper end of the fixing ring 10.

The lower end of the sealing cover 15 abuts against the upper end of the head 501. Three equally spaced second threaded holes 17 are formed through the upper end of the sealing cover 15. At the corresponding positions of the upper end of the steering wheel body 1 and the second threaded holes 17, first threaded holes 16 are formed. A fastening bolt 18 is threadedly connected inside the first threaded holes 16 and the second threaded holes 17.

[0040] Furthermore, the lower end of the sealing cover 15 abutting against the upper end of the head 501 can limit the screw body 5, reducing its displacement in the vertical direction due to vibration, and further improving the connection stability of the screw body 5. At the same time, the sealing cover 15 can effectively prevent external substances such as water and dust from entering the first fixing hole 3, thereby protecting the screw body 5 from corrosion and damage.

[0041] Working principle: During use, place the fixing ring 10 in the first installation groove 8 and snap the second clamping block 11 into the second clamping groove 9. Then place the steering wheel body 1 on the upper end of the rotating column 2 and align the first fixing hole 3 and the second fixing hole 4. Next, insert the screw rod 502 into the first fixing hole 3 and align the first clamping block 7 with the first clamping groove 6. Then use a riveting tool to push the head 501 of the screw body 5, so that the screw rod 502 is pressed into the second fixing hole 4 and the third fixing hole 1001. The debris generated during the riveting process will enter the groove 12, which can prevent excessive debris from accumulating between the screw rod 502 and the rotating column 2, thus affecting the connection quality or causing an incomplete riveting connection. After the riveting is completed, the first clamping block 7 snaps into the first clamping groove 6. At this time, install the sealing cover 15 inside the first fixing hole 3, align the first threaded hole 16 and the second threaded hole 17, and then install the fastening bolt 18 inside the first threaded hole 16 and the second threaded hole 17 to complete the riveting and fixing of the steering wheel body 1.
