Example

[0033] The solution in Example 1 will be further described below with reference to its specific working method.

[0034] like Figure 4 As shown, in a preferred embodiment, based on the above method, the connecting plates 2 are symmetrically distributed on the left and right sides of the protective pipe 1. The connecting plates 2 correspond one-to-one with the fixing frame 5 through the connecting shaft 4, which can ensure that the connecting plates 2 on both sides and the connecting shaft 4 cooperate with the splicing plate 3 to be connected and bent.

[0035] like Figure 3 As shown, in a preferred embodiment, based on the above method, the connecting plate 2 and the splicing plate 3 are further provided with holes at equal angles, and the end of the connecting shaft 4 is fixedly connected to the inner center of the fixing frame 5, which can ensure that the holes opened at equal angles can be positioned when the angle is adjusted.

[0036] like Figure 5 As shown, in a preferred embodiment, based on the above method, the side end face of the fixing frame 5 is in contact with the side end face of the connecting plate 2, and the length of the connecting frame 9 is greater than the length of the clamping rod 8, which can ensure that the clamping rod 8 can be retracted into the fixing frame 5 when the connecting frame 9 is pulled.

[0037] like Figure 6 As shown, in a preferred embodiment, based on the above method, the internal gear ring 13 is further connected to the fixed box 10, the rotating rod 11 is fixedly connected to the clamping plate 14, the fixed box 10 is threadedly connected to the positioning bolt 15, and the clamping plate 14 has an arc-shaped cross-section, which can ensure that the arc-shaped clamping plate 14 can conveniently clamp and limit the cable.

[0038] like Figure 6 As shown, in a preferred embodiment, based on the above method, the rotating rods 11 are distributed at equal angles on the fixed box 10, and the rotating rods 11 correspond one-to-one with the clamping plates 14 through the gears 12, which can ensure that the multiple clamping plates 14 can clamp and position the cable.

[0039] Specifically, cable protection structures that could limit the bending range are used in conjunction with: Figures 1-6 When installing cables of different sizes, the cables can be passed through the fixed box 10 and the protective pipe 1. During positioning, the rotating rod 11 on one side can be rotated to drive the gear 12 to rotate. The gear 12 can push the internal gear ring 13 to rotate inside the fixed box 10. At the same time, the internal gear ring 13 can drive multiple meshing gears 12 to rotate simultaneously. The rotating rod 11 on the gear 12 drives the clamping plate 14 to rotate. The clamping plate 14 can clamp and limit the installed cable, achieving the positioning effect and preventing it from falling off. After adjustment, the positioning bolt 15 on the rotating rod 11 can be rotated. The positioning bolt 15 can fit and be fixed on the fixed box 10, preventing the rotating rod 11 from rotating due to physical force, which is convenient for limiting and fixing cables of different sizes.

[0040] When adjusting the bending angle, the connecting frame 9 on both sides of the connecting plate 2 can be pulled. When the connecting frame 9 moves the limiting plate 7, it can compress the spring 6 in the fixed frame 5. The limiting plate 7 can also drive the locking rod 8 to disengage from the connecting plate 2 and the splicing plate 3 and return to the fixed frame 5. When the fixed frame 5 is unobstructed, the fixed frame 5 can be rotated to drive the connecting shaft 4 to rotate and adjust the protective pipe 1 on the connecting plate 2. After the rotation adjustment is completed, the connecting frame 9 is released, and the spring 6 pushes the limiting plate 7 and the locking rod 8 to reset. The locking rod 8 can be locked in the connecting plate 2 and the splicing plate 3, which makes it convenient to adjust the bending angle according to the usage.

[0041] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model.
