In the process of the cooperation rotation of the spiral gear of the adjusting gear 3 and the spiral part of the locking rod 2, due to the transmission force characteristic of the spiral gear, the adjusting gear 3 has both axial transmission force and circumferential transmission force, so that the adjusting gear 3 acts on the locking rod 2, namely, has circumferential rotation force and axial movement force. Under the action of the limiting groove 9 and the limiting part 10 which are matched with the gears, the locking rod 2 can respectively axially move and circumferentially rotate so as to realize two steps of insertion and locking on two adjacent display screen boxes. Under the normal operating condition, the adjusting gear 3 rotates to drive the locking rod 2 to move, when the limiting part 10 is positioned in the axial groove 9-1 of the limiting groove 9, the limiting part 10 limits the locking rod 2 to rotate in the circumferential direction and can only axially move, so that the locking rod 2 axially moves under the action of the adjusting gear 3 and can be inserted into the box body of the adjacent display screen. When the limiting part 10 reaches the end part of the axial groove 9-1 and is positioned in the axial groove 9-2, the limiting part 10 limits the axial movement of the locking rod 2, so that the locking rod 2 can only rotate circumferentially, and the locking rod 2 rotates circumferentially under the action of the adjusting gear 3, thereby realizing the locking of the locking rod 2 in the adjacent display screen box body.
Wherein the length of the axial groove 9-1 in the limit groove 9 is matched with the length required by inserting the end part of the locking rod 2 into the adjacent display screen box body to the locking position. And the length of the axial groove 9-2 of the limit groove 9 is matched with the angle of rotation required by the locking rod 2 to be locked after being inserted into the adjacent display screen box body.
