[0009] When the two sleeves slide back and forth, the two second bearings are pulled by the two connecting rods. When the two second bearings are pulled, the two transmission rods are driven to extend outward along the inside of the sleeve, thereby ensuring that the two active bevel gears are always meshed with the two driven bevel gears. When the two sleeves move back and forth, the two massage heads are driven to move back and forth to adjust the spacing through the two driven bevel gears. After the spacing adjustment is completed, the operator starts the driving motor to drive the worm to rotate along the positioning frame. When the worm rotates, the sleeve is driven to rotate inside the two first bearings through the worm gear. When the sleeve rotates, the two active bevel gears are driven to rotate through the two transmission rods. When the two active bevel gears rotate, the two massage heads are driven to rotate and massage through the two driven bevel gears. This allows the neck massage pillow to adjust the spacing between the two massage heads according to the thickness of the necks of different people, thereby ensuring the massage effect.
