The composite elastic body 2 is inserted into the fast-packaging box 1, and the composite elastic body 2 can be conveniently checked into or detached from the fast-packaging box 1.

When the composite elastic body 2 is inserted into the quick-loading box 1 for operation, the positioning elastic sheet 2-2 is firstly pressed and deformed, and the angle of the positioning elastic sheet relative to the base 2-1 is reduced. When the positioning elastic sheet 2-2 reaches the positioning through groove 1-3, the positioning elastic sheet is automatically lifted, and the upper end of the positioning elastic sheet 2-2 further enters the positioning through groove 1-3 and is clamped.

The composite elastic body 2 comprises a base 2-1, a forward elastic sheet 2-3, a backward elastic sheet 2-4 and a positioning elastic sheet 2-2, wherein the positioning elastic sheet 2-2 is arranged at the front end of the base 2-1; the forward elastic piece 2-3 and the backward elastic piece 2-4 are simultaneously arranged at the rear end of the base 2-1.

The fast-assembling box 1 is installed on the fixing seat A in a glue-binding mode.

The quick-loading box 1 is a shell 1-1 with an opening at one end, and a positioning through groove 1-3 is formed in the upper end face of the shell 1-1; the upper side of the opening end of the shell 1-1 is provided with an inclined plane 1-2. The height of the inner cavity of the shell 1-1 is larger than the thickness of the base 2-1, and the installation is convenient.

The backward elastic sheets 2-4 are symmetrically arranged on the base 2-1 relative to the forward elastic sheets 2-3; the upper end surfaces B of the backward elastic pieces 2-4 and the forward elastic pieces 2-3 are positioned in the same horizontal plane, so that the elastic contact range is enlarged, and the operation stability is improved; the included angles of the backward elastic sheet 2-4 and the forward elastic sheet 2-3 relative to the horizontal plane are both 30-40 degrees, and the installation directions of the backward elastic sheet 2-4 and the forward elastic sheet 2-3 are opposite.
