A long groove 12 is provided in the center of the connecting portion 11 for sleeved on the connecting assembly 20 on the mounting frame 30. A fixing hole 14 is provided on one side of the middle portion of the supporting portion 13 near the free end, for fixing the width adaptive device on the equipment to be supported. The upper and lower sides of the free end of the supporting portion 13 are respectively provided with a first U-shaped groove 16 and a second U-shaped groove 18, and the U-shaped opening of the first U-shaped groove 16 faces downward, and the U-shaped opening of the second U-shaped groove 18 faces outward (i.e., the side away from the connecting portion 11). A first mounting hole 15 and a second mounting hole 17 are respectively provided on both sides of the opening ends of the first U-shaped groove 16 and the second U-shaped groove 18.
