The first base 4 and the second base 5 are mounted with a massage. The adjusting device 6 includes a worm wheel 61, a first screw 62, a second screw 63, a third screw 64, a fourth screw 65, a central shaft 66, a first rack 68 and a second rack 67, The first screw 62, the second screw 63, the third screw 64, and the fourth screw 65 are provided with engaging portions on one side thereof, which can be clamped together. The first screw 62 passes through the central shaft 66 and the second screw 63 and the third. The screw 64 and the fourth screw 65 are sequentially connected, the worm gear 61 meshes with the second screw 63 and the third screw 64, and the first rack 68 meshes with the first screw 62, A fourth rack gear 67 engaging two screws 65. The first rack 68 and the second rack 67 are threaded, and the second rack 67 is disposed in parallel on the lower surface of the first base 4, and is integrally formed with the same shape. The first rack 68 is disposed in parallel on the lower surface of the second base 5, and is integrally formed therewith. The track plate 3 includes two parallel sliding bars 31 and two baffles 32, and the two sliding bars 31 are sequentially connected with the two baffles 32 to form a rectangular frame, the first base 4 and a lower side of the second base 5 is provided with a sliding slot 33, the first rack 68 passing through the sliding slot 33 of the first base 4, symmetrically The second rack 67 passes through the sliding slot 33 of the second base 5 and above the sliding rod 31, the two sliding rods 31 correspondingly pass through the sliding of the first base 4 and the second base 5 The groove 33 is provided below the first and second racks 68, 67 and is fixed to the lower cover 1. The elastic piece 74 is caught in the adjacent tooth groove 75 of the internal gear 72. The thickness of the elastic piece 74 is smaller than the width of the tooth groove 75. When the width of the massage head is adjusted, since the elastic piece 74 is caught in the tooth groove 75, When the upper cover 71 is rotated, the elastic piece 74 is automatically rotated in the internal meshing gear 72, thereby making a sound, informing people that the function of adjusting the width of the massage head is being used.
