For example, spaced body assemblies 12 may be distributed on opposite sides of the body 10, and spaced cover assemblies 22 may be distributed on opposite sides of the cover 20, thereby increasing the strength of the connection between the body 10 and the cover 20.

It should be noted that the number of the body assemblies 12 on one side of the body 10 and the number of the cover assemblies 22 on one side of the cover 20 can be arbitrarily adjusted according to the actual design length of the body 10 and the cover 20, and the present application is not limited thereto.

In one embodiment, the cover 20 is movable along the first direction F1 relative to the body 10, so that the cover assemblies 22 and the body assemblies 12, which are alternately disposed along the first direction F1, are separated from each other or inserted into each other (refer to the state shown in fig. 2A and 2B).

In another embodiment, the cover 20 can be moved relative to the body 10 along a second direction F2 perpendicular to the first direction F1, such that the cover assemblies 22 and the body assemblies 12 are staggered (refer to the state shown in FIGS. 2A and 2B) or aligned (refer to the state shown in FIG. 3) along the first direction F1

Alternatively, along the second direction F2, the first width W1 of each body assembly 12 is not greater than the second distance D2 between two adjacent cover assemblies 22, and the second width W2 of each cover assembly 22 is not greater than the first distance D1 between two adjacent body assemblies 12 (refer to fig. 2B), so that each cover assembly 22 and each body assembly 12 in the staggered arrangement can be relatively moved along the first direction F1.

Alternatively, the first width W1 of each body assembly 12 and the second width W2 of each cover assembly 22 may be set to not less than 2 mm.

Optionally, the first width W1 of each body assembly 12, the first spacing D1 between two adjacent body assemblies 12, the second width W2 of each cover assembly 22, and the second spacing D2 between two adjacent cover assemblies 22 are all equal.

Illustratively, the first width W1 of each body assembly 12, the first spacing D1 between two adjacent body assemblies 12, the second width W2 of each cover assembly 22, and the second spacing D2 between two adjacent cover assemblies 22 may all be set to 4 millimeters.

Alternatively, the first height of each body assembly 12 and the second height of each cover assembly 22 along the first direction F1 may be designed to be equal or different.

Optionally, the first height of the body assembly 12 is less than the first width W1.
