Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 The electric massage device of this utility model includes a mounting shell 1 and a massage mechanism installed inside the mounting shell 1. The massage mechanism includes a movable slide 2, a massage component mounted on the movable slide 2, a drive mechanism for moving the movable slide 2, and a guide mechanism 12 for guiding the movable slide 2. The drive mechanism includes a drive motor 4, a screw 5 connected to the output end of the drive motor 4, and a nut 6 screwed to the screw 5. The nut 6 is installed on the movable slide 2. The front and rear ends of the movable slide 2 are respectively provided with a first bearing 8 and a second bearing 9. The screw 5 passes through the first bearing 8, the nut 6, and the second bearing 9 in sequence. The drive motor 4 directly drives the screw 5 to rotate. The screw 5 passes directly through the movable slide 2 through the first bearing 7, the nut 6, and the second bearing 9 in sequence. The movable slide 2 moves synchronously through the nut 6. The first bearing 8 and the second bearing 9 make the screwing connection between the nut 6 and the screw 5 more stable, improving the operational stability of the movable slide 2.
