Therefore, one side of the movable piece 2 abuts against the side wall of the sliding groove 110 on the fixed plate 1, and the other side is in interference fit with the limiting section 310 for clamping. During installation, the handle 320 of the buckle 3 is moved to deflect the limiting section 310, thereby expanding the width of the sliding groove 110. The movable piece 2 is slid into the sliding groove 110 from the top end or the bottom end of the sliding groove 110 and is moved to the appropriate height. Then, the handle 320 of the buckle 3 is moved to deflect the limiting section 310, thereby reducing the width of the sliding groove 110 until the limiting section 310 abuts against and presses the movable piece 2. In this embodiment, the limiting section 310 is made of silica gel. When the movable piece 2 is in interference fit with the limiting section 310, the movable piece 2 cannot be moved up and down. When the pillow body 6 of the headrest needs to be disassembled, the handle 320 of the buckle 3 is moved to deflect the limiting section 310 to release the interference fit with the movable piece 2. At this time, the movable piece 2 can be moved up and down in the sliding groove 110 to achieve relative position adjustment.

[0039] Referring to the drawings Figure 2 In the above embodiment, a protrusion 120 is arranged at the edge of one side of the sliding groove 110 to form a clamping groove 111 in the sliding groove 110.
