Further, in this embodiment, as shown in fig. 3d, one end of the first section of connecting rod 31 (i.e. the upper end of the first end connecting rod in fig. 3 d) far away from the massage head assembly 4 extends into the inside of the second section of connecting rod 32 to form a boss 311, a fastening groove 312 is formed between the outer side wall of the boss 311 and the inner side wall of the second section of connecting rod 32, one end of the elastic element 5 close to the massage head assembly 4 is fastened in the fastening groove 312 to position the elastic element 5, so as to prevent the problem that the one end of the elastic element 5 close to the massage head assembly 4 is unreliable due to the fact that there is no limiting device to abut against the connecting rod 3.

It should be noted that the size of the snap groove 312 may be specifically determined according to the size of the elastic member 5, and this embodiment is not particularly limited thereto.

In this embodiment, as for the formation manner of the clamping groove 312, the wall thickness of the second section of connecting rod 32 may gradually decrease along the direction toward the first housing 11; and the wall thickness of the first section connecting rod 31 forming the boss 311 is gradually reduced along the direction towards the first casing 11, so that the part of the first section connecting rod 31 extending into the second section connecting rod 32 has a gap between the second section connecting rod 32, that is, the clamping groove 312 is formed, thereby avoiding the interference between the massage head component 4 and the elastic member 5 when the massage head component moves circumferentially, and improving the use reliability.
