The invention provides a connecting female part and a connecting structure. The connecting female part is used for being connected with a first structural part and comprises a cylinder part and a connecting part. The cylinder part is provided with a first end and a second end which are oppositely arranged in the axis direction of the cylinder part, a first contraction opening is formed in the first end of the cylinder part in a penetrating mode in the radial direction of the cylinder part, and a second contraction opening is formed in the second end of the cylinder part in a penetrating mode in the radial direction of the cylinder part, so that the cylinder part has a certain contraction space in the radial direction of the cylinder part. The connecting part is arranged on the periphery of the cylinder part and used for being connected and matched with a first structural part. The sum of the length of the first contraction opening and the length of the second contraction opening in the axis direction of the b
