Embodiment 1
[0038] Such as Figure 1-6 As shown, a wire passing protection structure of the present invention is arranged at the end of a first object formed with a first wire passing hole 12, and the wire passing protection structure includes a wire protection structure with a second wire passing hole 21. Grinding structure 2, after the electric wire 3 passes through the second wire passing hole 21 and the first wire passing hole 12, it is in contact with the wear-resistant structure 2 during the movement under the action of an external force, wherein When relative motion occurs between the anti-wear structure 2 and the electric wire, the contact surface of the anti-wear structure 2 that contacts the electric wire is smooth. Due to the setting of the anti-wear structure 2, the electric wire 3 no longer contacts and rubs with the first object during the movement, but contacts and rubs with the anti-wear structure 2, and since the contact surface between the anti-wear structure 2 and the e...
Embodiment 2
[0046] Such as Figure 7-10 As shown, the difference between Embodiment 2 and Embodiment 1 is that when the relative movement between the anti-wear structure 2 and the electric wire 3 cannot be set, the relationship between the anti-wear structure 2 and the first object A relative motion setting can be generated, and driven by the electric wire 3, the anti-wear structure 2 moves relative to the first object. Due to the setting of the anti-wear structure 2, the electric wire 3 is no longer in contact with the first object, but is in contact with the anti-wear structure 2 during the moving process, and since the anti-wear structure 2 and the electric wire 3 cannot produce relative motion settings, The wear-resistant structure 2 can move relative to the first object under the action of the electric wire 3, so that the friction can be transferred between the wear-resistant structure 2 and the first object. Therefore, the wear-resistant structure 2 in contact with the electric wire...
