[0023] As attached Figure 2 , 3As shown in , 5, notches are provided on the surfaces of both sides of the two arc-shaped rods 4, and two extension rods 8 are provided inside the two notches. One ends of the two extension rods 8 pass through the notches and extend to one side of the arc-shaped rod 4, and a moving assembly is provided between one end of the two extension rods 8 and the protective plate 2; the moving assembly includes a moving block 9 arranged on one side of the two extension rods 8, moving grooves are provided on the surfaces of the two protective plates 2, and a plurality of fixing holes 10 are provided on the surfaces of the two protective plates 2 and at the bottom of the moving grooves, and a sliding rod 11 is provided inside the two moving grooves, and the two moving blocks 9 are sleeved on the sliding rod 11, and a connecting plate 12 is provided at the bottom of the two moving blocks 9 and at one side of the protective plate 2. By pulling the moving block 9, the extension rod 8 and the arc-shaped rod 4 are driven to move along the sliding rod 11, so that the position of the arc-shaped rod 4 can be adjusted.

[0024] As attached Figure 5 As shown, a pull rod 13 is provided on one side of the two connecting plates 12, and grooves are opened on the surfaces of the two connecting plates 12. One end of the two pull rods 13 passes through the surface of the connecting plate 12 and extends into the groove. A fixing rod 14 is provided at one end of the pull rod 13. The fixing rod 14 can be extended and pulled to move it into the groove, thereby releasing the restriction on the moving block 9.

[0025] As attached Figure 4 As shown, a limiting plate 15 is provided at one end of the two extension plates 5 and inside the through slot, which can limit the extension plates 5 and prevent the extension plates 5 from falling off from the through slot.

The positions of the two arc rods 4 on the placement plate 1 can be adjusted according to the bending shape of the high-voltage wire distribution at the bottom of the car. The convex surface formed by the two arc rods 4 can make the arc rod 4 combined with the surface of the high-voltage wire, which can improve the stability of the protection of the high-voltage wire. The utility model can be suitable for different models of cars by adjusting the width of the placement plate 1, and the position of the protrusion on the placement plate 1 can be changed by moving the position of the two arc rods 4.
