The handle ring 402 is sleeved around the top of the side surface of the handle body 401, and the handle holding ring groove 403 is opened around the bottom of the side surface of the handle body 401.

[0023] More specifically, by setting a handle holding groove 403 around the bottom of the side surface of the handle body 401, the feel is more comfortable and the effect of preventing it from slipping out of the hand is better.

[0024] In this utility model, the elastic metal loading sleeve 1 is an arc-shaped sleeve structure that fits the curvature of the steering wheel and is open at the bottom and both ends. The internal threaded ring 8 is provided on the inner arc side of the elastic metal loading sleeve 1, and the cavity ring 9 is provided on the outer arc side of the elastic metal loading sleeve 1. The inner side of the cavity ring 9 is connected to the through hole 7 of the elastic metal loading sleeve 1.

[0025] More specifically, by setting the inner side of the cavity ring 9 to communicate with the through hole 7 of the elastic metal loading sleeve 1, it can bear the function of accommodating the bolt fastening plug 12.

[0026] In this utility model, a fastening groove 6 is provided on the inner side of the steering wheel touch pad 5. The fastening groove 6 is a straight groove, and there are multiple fastening grooves 6 that are equally spaced and parallel.

[0027] More specifically, by setting multiple equally spaced parallel fastening grooves 6, the anti-slip effect is improved.

[0028] In this utility model, the bolt fastening plug 12 includes an external thread plug 1201 and an alignment platform 1202. The end face of the alignment platform 1202 coincides with the end face of the external thread plug 1201 and is fixedly connected. The alignment platform 1202 has a frustum-shaped structure.

During the installation process, the sliding shaft 11 is slid, allowing the bolt fastening plug 12 to slide into the cavity ring 9, ensuring unobstructed access at the bottom of the elastic metal loading sleeve 1 for fastening. This allows the steering wheel contact pad 5 on the inner side of the elastic metal loading sleeve 1 to adhere to the steering wheel rim. Then, the sliding shaft 11 is pushed forward, causing the bolt fastening plug 12 to engage with the internal threaded ring 8. The knob plug 13 is then turned, causing the bolt fastening plug 12 to screw into the internal threaded ring 8, thereby causing the knob plug 13 to fasten the outer side of the elastic metal loading sleeve 1. This causes the bottom of the elastic metal loading sleeve 1 to clamp inward, thus clamping and securing the steering wheel rim. The entire operation can then be performed by gripping the power steering sleeve handle 4 downwards.
