[0021] During implementation, the T-bar 52 is rotated to drive the rectangular buckle 55 to pass through the rectangular groove 54 and buckle into the inside of the circular groove 56. Then, the T-bar 52 is rotated to make the rectangular buckle 55 and the rectangular groove 54 staggered with each other. Then, the elastic force of the tension spring 53 pushes the T-bar 52 to move outward, thereby fastening the shell 1 and the shell cover 2.
