For example, four radial arms 231 may be disposed, and the four radial arms 231 are uniformly disposed around the positioning column 232, and the four radial arms 231 are disposed to enhance the connection strength between the box cover 20 and the box body; of course, the radial arms 231 may be provided in other numbers, and may be determined according to practical situations, which is not limited only herein.

Further, the radial arm 231 is configured as an L-shaped structure (as shown in fig. 6), and the torsion bar 2311 of the radial arm 231 is fixed to the bottom 22 of the box cover, so that the radial arm 231 has elasticity, and when the rotary buckle 23 receives an external force, the clamping bar 2312 drives the torsion bar 2311 to rotate, that is, at this time, the torsion bar 2311 can be regarded as bending deformation under the action of the external force, so that the purpose of clockwise or anticlockwise rotation of the rotary buckle 23 is achieved.
