  • a cover body having two sides, an outside of a lower end of each of said sides being provided symmetrically with a plurality of inverted U-shaped locking plates and a front end of said cover body being provided with a plurality of locking plates which extend outwardly and form a plurality of first grooves with a top surface of said cover body;

    a base having a vertically-extending surface on a front end thereof and an edge extending inwardly from a top of said vertically extending surface for engaging with said first grooves of said cover body, said base further comprising a plurality of recesses on two sides thereof;

    the positions of said recesses corresponding to those of said inverted U-shaped locking plates of said cover body so that the recesses can mate with the locking plates when the cover body is lowered upon the base;
