[0024] Embodiment 2:

[0025] On the basis of Embodiment 1, as Figure 1 and Figure 4As shown in the figure, auxiliary blocks 11 are fixedly installed on one side of each of the two L-shaped blocks 7. Concave holes 13 are provided on both sides of the top end of the shield body 1. One side of each of the two clamping members 6 is in contact with both sides of the steering column member 3 respectively. A compressive layer 16 is provided inside the shield body 1. In a car steering column shield of the present utility model, by providing the L-shaped blocks 7, auxiliary blocks 11, twisting strips 12, compressive layer 16 and concave holes 13, the compressive layer 16 is made of polypropylene material, which has good compressive resistance and durability, ensuring that the shield body 1 does not deform under pressure and extending the service life of the shield body 1. After the L-shaped blocks 7 are installed with the vertical blocks 9, the auxiliary blocks 11 are located directly above the shield body 1.

[0026] Working principle: The car steering column is a key component of the vehicle steering system. It connects the steering wheel and the steering gear, transmitting the driver's steering input to the wheels. The sheath of the car steering column plays a role in protection and safety during installation. The shield is mainly used to protect the steering column from the influence of the external environment, such as dust and moisture, and also plays a role in shock absorption and protecting the driver's safety in the event of a collision. The car steering column shield includes a corrugated pipe 2, which is used to wrap cables and hoses to prevent them from being physically damaged, while allowing the steering column to maintain flexibility during rotation. After the steering column member 3 is installed inside the shield body 1, the bottom surface of the positioning sleeve 4 is in contact with one end of the shield body 1. The two L-shaped blocks 7 are respectively in contact with the corresponding vertical blocks 9. One end of each of the two limit bolts 8 is inserted into the two limit holes 10 in sequence, and the two are threadedly connected. Then, the twisting strip 12 is inserted into the concave hole 13, and the two are threadedly connected, so as to limit and fix the steering column member 3 and the shield body 1, ensuring the stability of their installation. The combined use of the limit bolt 8 and the twisting strip 12 can evenly distribute the fixing force, provide better stability, reduce the movement and vibration of the shield body 1 during operation, and can also disperse the stress applied on the shield body 1 to avoid damage caused by concentrated stress, thus reducing the frequency of replacing the shield body 1. Rotate the screw 5 in sequence to make one side of each of the two clamping members 6 clamp both sides of the steering column member 3. The wear-resistant layer 14 is made of polycarbonate material, which has excellent wear resistance and impact resistance. The foam layer 15 is filled with polyurethane foam inside the shield body 1, which is used to provide buffering and sound insulation functions, and at the same time increase the comfort and safety of the shield body 1. The compressive layer 16 is made of polypropylene material, which has good compressive resistance and durability, ensuring that the shield body 1 does not deform under pressure and extending the service life of the shield body 1. After the L-shaped blocks 7 are installed with the vertical blocks 9, the auxiliary blocks 11 are located directly above the shield body 1. Rotate the twisting strip 12 to threadedly install the twisting strip 12 with the concave hole 13, further enhancing the installation stability of the shield body 1 and the steering column member 3.
