In some cases, the width L of the support rib 3351 located in the first support region 3354 decreases in the direction away from the second support region 3355, improving the bending capability of the carbon fiber bearing portion 33. In some embodiments, the width L of the support rib 3351 in the first direction in the second support region 3355 is uniform in the first direction, so that the stress in the carbon fiber bearing portion 33 is uniformly distributed, and the bending capability is ensured. In some cases, the space width M between two adjacent support ribs 3351 in the first support region 3354 decreases in a direction away from the second support region 3355, improving the bending capability of the carbon fiber bearing portion 33. In some embodiments, the space width M between two adjacent support ribs 3351 in the second support region 3355 is uniform in the first direction, so that the stress in the carbon fiber bearing portion 33 is uniformly distributed, and the bending capability is ensured.
