The lock 31 is arranged on the cover 20, the buckle portion is arranged on the base 10, the buckle portion and the lock are fastened together, the adjustment portion is arranged on the base 10, and the adjustment portion is provided with a cable groove 32 for accommodating cables. The buckling of different locks 31 with the lock portion can realize multi-stage adjustment of the cover 20 and the base 10, thereby changing the size of the cable groove 32, and then adapting to cables of various cable diameters. The adjustment portion in this embodiment can be detachably connected to the base, or fixedly connected. This embodiment is described by taking the fixed connection of the adjustment portion and the base as an example.

The multi-stage buckle assembly 30 also includes two connecting ears 34, a connecting groove 33 and a pin 341, as shown in Figure 1-2; the connecting groove 33 is arranged between the buckle part and the adjustment part, wherein the buckle groove 331 is arranged on the inner wall of the connecting groove 33. In this embodiment, the buckle groove 331 is arranged on a side wall of the connecting groove 33 away from the adjustment part, the lock buckle 31 is arranged on the outer side of the cover plate 20, and the connecting ear 34 is arranged on the inner side of the cover plate 20, that is, the connecting ear 34 and the lock buckle 31 are respectively located on both sides of the cover plate 20, and the two connecting ears 34 are respectively arranged on both sides of the connecting groove 33. The pin 341 is inserted into the connecting hole (not shown in the figure) of the connecting ear 34 to achieve a detachable connection with the connecting ear 34; the pin 341 is tightly pressed against the other side of the cable groove 32, which not only presses the cable tightly and improves the stability of the cable fixation, but also prevents the cover plate 20 from being disengaged after any part of the cover plate 20 is broken, thereby further ensuring driving safety.

Preferably, there are multiple buckle slots 331, and multiple buckle slots 331 can be buckled with the lock buckle 31, that is, multiple lock buckles 31 can be buckled with the buckle slots 331 at the same time, or one of the lock buckles 31 is buckled with the buckle slot 331, which can achieve the adjustment of the size of the cable slot 32. Multiple lock buckles 31 are buckled with multiple buckle slots 331, making the buckle of the fixture more stable and not easy to disengage. As a further preferred embodiment, multiple lock buckles 31 are arranged side by side, and the lock buckle 31 has a certain length, and the length direction of the lock buckle 31 is consistent with the axis of the cable slot 32.

The adjustment part includes a first adjustment block 35 and a second adjustment block 36. As shown in FIG3 , the first adjustment block 35 is arranged at the rotating connection end of the base 10 and is pressed against the inner side of the cover plate 20, and the second adjustment block 36 is arranged at the buckle connection end of the base 10 and is pressed against the inner side of the cover plate 20; the first adjustment block 35, the second adjustment block 36, the base 10 and the cover plate 20 enclose a cable groove 32 for accommodating cables, and the shapes of the first adjustment block 35 and the second adjustment block 36 can be arc-shaped. In this embodiment, the specific shapes of the first adjustment block 35 and the second adjustment block 36 are adapted to the installed cables. Preferably, the adjustment part is fixedly connected to the base 10, and the first adjustment block 35 and/or the second adjustment block 36 are made of elastic material. When different lock buckles 31 are buckled with the connection groove 33, the cover plate 20 presses against the first adjustment block 35 and/or the second adjustment block 36 to different degrees, so that the size of the cable groove 32 changes, thereby pressing against the cables to adapt to cables with different cable diameters. In this embodiment, the elastic material of the first adjustment block 35 and/or the second adjustment block 36 can be selected from existing PA66, PA12 or PA6. As a further preferred embodiment, the adjustment part is detachably connected to the base 10. When different lock buckles 31 are engaged with the connection groove 33, different adjustment parts are used to change the size of the cable groove 32 formed by the first adjustment block 35 and the second adjustment block 36 to adapt to cables with different cable diameters.

As a further preferred embodiment, a first protrusion 37 and a second protrusion 38 are provided on the inner side of the cover plate 20. As shown in FIG2/5, the first protrusion 37 is pressed against the first adjustment block 35, and the second protrusion 38 is pressed against the second adjustment block 36.
