A locking structure for a draw-type electronic device includes a handle member, two connecting rod members, and two linked members. The handle member and the linked members are pivotally connected on a case of the electronic device respectively in a rotatable relation. The connecting rod members are connected to the handle member and the linked members. A first fastening groove and a second fastening groove are disposed on each of the linked members and the handle member respectively. The handle member is rotated to enable the connecting rod members to actuate the linked members to rotate together, so as to enable the first fastening groove and the second fastening grooves to apply forces on two corresponding positioning pins together, so that an action of electrical connection is accomplished.
