A locking device, comprising a first fixation device (1), a second fixation device (2), a locking rod (3) and an adjustment nut (4); one end of the locking rod (3) is connected to the adjustment nut (4), and the first fixation device (1) is sleeved at the other end of the locking rod (3); and the second fixation device (2) is provided between the first fixation device (1) and the adjustment nut (4), and has a sliding fit with the locking rod (3). Thus, the locking rod passes through edges of two LED screens, or passes through an edge of the LED screen and an edge of a support so as to enable two edges to be located between the first fixation device and the second fixation device, and then the adjustment nut is rotated to realize an installation of the LED screen, thus enabling an operation to be convenient and easy, and facilitating the splicing and erection of LED screens. |
