[0021] Example 1

[0022] like Figure 1 , Figure 2 As shown, the present invention provides the following technical solutions: a cable protection device for a steering wheel system, the device is used to protect the cables of the steering wheel, the device includes a wire clamp adapter plate 2, the wire clamp adapter plate 2 is installed at the steering wheel outlet; it also includes a wire clamp fixing block 4, the wire clamp fixing block 4 is installed on the wire clamp adapter plate 2; the device also includes a detachable fixing ring 1, the detachable fixing ring 1 is fixed on the wire clamp fixing block 4, the device also includes a rubber sleeve 3, the rubber sleeve 3 is arranged on the inner side of the detachable fixing ring 1.

[0023] Furthermore, the wire clamp adapter plate 2 is installed on the rotating surface inside the slewing bearing of the steering wheel system through a pair of first countersunk screws 7. The wire clamp adapter plate 2 is provided with two pairs of countersunk holes with different spacings and two pairs of countersunk holes with the same spacing. The wire clamp adapter plate 2 is circular, and a circular hole is opened in the center of the wire clamp adapter plate 2.

[0024] Furthermore, the wire clamp fixing block 4 is T-shaped, and a round hole is opened on the narrow side of the wire clamp fixing block 4.
