The opening sidewall 121 defines a first through hole 140 communicating with the accommodating space 130 . The locking member 200 includes a body 210 , a first extension portion 220 and a second extension portion 230 . The body 210 is disposed in the accommodating space 130 and fixed on the bottom 110 of the lower case 100 . The first extension portion 220 is disposed adjacent to the opening sidewall 121 . The first extension part 220 has a first end 221 and a second end 222 opposite to the first end 221 . The first end 221 is connected to the body 210 . The first extension portion 220 defines a second through hole 223 . The second through hole 223 is corresponding to the first through hole 140 . Wherein, as shown in FIG. 1 , the first through hole 140 and the second through hole 223 are used for locking with the Kensington lock 20 . The Kensington lock 20 is inserted into the first through hole 140 and the second through hole 223 as shown by the solid line in FIG. 1 , and then locked in the locking structure 10 as shown by the dotted line in FIG. 1 . Referring back to FIG. 2 , the second extension portion 230 is disposed on the second end 222 of the first extension portion 220 . The second extension 230 has an end 231 opposite to the second end 222 . The end portion 231 extends a distance D away from the bottom portion 110 .
