[0024] like Figure 2As shown, a flexible sleeve 116 is further provided on the outside of the first shell 112. After the first shell 112 and the second shell 121 are connected, the end surface of the second shell 121 abuts against the flexible sleeve 116. The flexible sleeve 116 is provided with a storage cavity 1161 for storing external components at one end facing away from the massage part 120. The provision of the flexible sleeve 116 can make the user hold the hand more comfortable, and can also absorb the vibration caused by the operation of the massage part 120. The flexible sleeve 116 can be made of a flexible silicone material.

[0025] In this embodiment, the connecting shaft 123 is a spring shaft, the second housing 121 is in an upright state by default, and the portion of the second housing 121 that is sleeved with the connecting shaft 123 is made of a deformable material. Figure 8 As shown, when the connecting shaft 123 is a spring shaft, the massage part 120 has a preset bend, and the second housing 121 is in a bent state by default. The connecting end of the connecting shaft 123 and the output shaft 1131 is provided with a plug-in connector 125, which passes through the through hole 1171 and is detachably connected to the output shaft 1131.

[0026] Since the connecting shaft 123 is connected between the eccentric block 122 and the output shaft of the motor 113, and the connecting shaft 123 is a slender rod-shaped structure, the slender connecting shaft 123 can amplify the vibration of the eccentric block, and the vibration effect is better than that of the prior art. Moreover, since the connecting shaft 123 is made of a steel material or a nylon material, such a connecting shaft 123 has good rigidity and meets the requirement of long-term use of a slender connecting rod; when the connecting shaft 123 uses a spring shaft, the angle between the eccentric block 122 and the motor 113 can also be changed.
