The locking groove 64 and the locking protrusion 62 each have an arc-shaped cross section, and the width of the root of the locking protrusion 62 is greater than the width of the tip of the locking protrusion 62, the width of the open end of the locking groove 64 is greater than the width of the bottom of the locking groove 64, and the width of the locking protrusion 62 is gradually reduced from the root to the tip.

The locking groove 64 and the locking protrusion 62 are in clearance fit in the circumferential direction, that is, the width of the locking groove 64 in the circumferential direction is greater than the width of the locking protrusion 62 in the circumferential direction, the depth of the locking groove 64 is greater than the height of the locking protrusion 62, the width of the open end of the locking groove 64 is greater than the width of the root of the locking protrusion 62, and one side of the locking protrusion 62 is pressed against one side of the locking groove 64 to engage the locking protrusion 62 with the locking groove 64. In this way, the same side of the plurality of locking projections 62 in the circumferential direction presses one side wall of the corresponding locking groove 64 to effect the engagement of the first engaging portion 61 with the second engaging portion 63.

When the arc-shaped side surface of the locking protrusion 62 is pressed against the arc-shaped side wall of the locking groove 64, torque can be transmitted between the first engagement part 61 and the second engagement part 63; when the torque between the first engaging portion 61 and the second engaging portion 63 is greater than the opening force, the arc-shaped side surface of the locking protrusion 62 and the arc-shaped side wall of the locking groove 64 slide relative to each other, when the locking protrusion 62 is pressed against the end surface of the first engaging portion 61 or the second engaging portion 63, the first engaging portion 61 is disengaged from the second engaging portion 63, and the locking protrusion 62 slides along the end surface of the first engaging portion 61 or the second engaging portion 63 to the other locking groove 64, i.e., the rotation of the display terminal 101 is realized.

That is, the width of the locking groove 64 becomes gradually larger from the inside to the outside in the radial direction, and the width of the locking projection 62 becomes gradually larger from the inside to the outside in the radial direction. It can be understood that when the first engaging portion 61 and the second engaging portion 63 transmit torque, the torque applied to the outer ends is large, and the strength of the outer ends can be enhanced by the above structure, thereby preventing breakage.
