Second snap ring 415 has an inner annular surface and an outer annular surface, the inner annular surface of second snap ring 415 is coplanar with the inner wall of connecting shaft 412, and the edge of the outer annular surface of second snap ring 415 away from electrode holder 411 is provided with an inclined chamfer. The connecting shaft 412 includes four arc-shaped shaft walls arranged at intervals, and the four arc-shaped shaft walls and the intervals between the four arc-shaped shaft walls surround to form the cylindrical connecting shaft 412. Second snap ring 415 includes four spaced second sub-snap rings, which surround second snap ring 415 in a circular ring shape with spaces therebetween. The second daughter card rings are fixed in the middle of the arc-shaped shaft wall in a one-to-one correspondence mode. With this arrangement, in order to adjust the radial dimension of the second snap ring 415, the connecting shaft 412 is conveniently installed in the connecting seat 2 through the first through hole 211.

In addition, in some other embodiments of the present application, the connecting shaft 412 of the massage part 41 may not be connected to the holding arm 1 through the connecting seat 2, but the connecting shaft 412 is directly and fixedly connected to the second cover 112 of the holding arm 1, and when the holding arm 1 is rotated and folded, the massage part 41 is naturally driven to rotate and fold together; when the holding distance between the two holding arms 1 is widened, the distance between the two massage portions 41 is naturally widened.

Also, three, four, or more massage portions 41 may be provided; at least part of the massage part 41 can be connected with the holding arm 1 through the connecting seat 2, or at least part of the massage part 41 can be directly and fixedly connected with the second cover 112 of the holding arm 1. The connection relationship has already been described in detail above, and therefore, the description thereof is omitted here.

The massager can further comprise an adjusting mechanism, and the adjusting mechanism is arranged on the two clamping arms 1 and used for adjusting the clamping distance between the two clamping arms 1.

Specifically, the adjustment mechanism may include an elastic member connected between the two connection shafts 412. As shown in fig. 1 and fig. 2, the elastic element may be an elastic ring 5 sleeved outside the two connecting shafts 412. In addition, the elastic member may be a tension spring connected between the two connecting shafts 412, and a stretching direction (mounting direction) of the tension spring may coincide with an extending direction of the first groove 13.

Referring to the schematic structural diagram of the massager shown in fig. 8 in the unfolded state, when a user uses the massager, the two clamping arms 1 can be respectively held by two hands of the user, the two clamping arms 1 are pulled to both sides with force, the rotating shafts 12 of the two clamping arms 1 drive the connecting shaft 412 of the massage portion 41 to slide outwards, the rotating shafts 12 slide along the second through holes 221, and the connecting shaft 412 slides along the first through hole 211. The positioning block 33 will slide outwards in the first groove 13, so that the distance between the two connecting shafts 412 will be increased, the elastic ring 5 sleeved outside the two connecting shafts 412 will be expanded to generate an inwards contracting force (the tension spring connected between the two connecting shafts 412 will be pulled apart to generate an inwards contracting force), the distance between the two rotating shafts 12 will also be increased, so that the clamping distance between the two clamping arms 1 is increased to form a state of the massage apparatus shown in fig. 9, in which the arrow indicates the adjusting direction. After the user wears the neck, under the action of the contraction force of the elastic ring 5 (or the extension spring), the connecting shafts 412 of the two massage parts 41 can slide inwards in the first through holes 211, the rotating shafts 12 of the two clamping arms 1 can slide inwards in the second through holes 221, and the positioning blocks 33 can also slide inwards in the first grooves 13, so that the distance between the two connecting shafts 412 can be reduced, the distance between the two rotating shafts 12 can be reduced, and the size of the part (for example, the neck, the waist and abdomen, the four limbs, the head and the like) to be massaged of the user can be matched until the part is reached. Since the size of the part to be massaged of different users is different, the two holding arms 1 hold the part to be massaged of the users, therefore, the holding distance X between the two holding arms 1 is different along with the size of the part to be massaged of the users, so as to adapt to different users.

The structure of the adjusting mechanism is not limited to the above description, for example, the adjusting mechanism may include two compression springs, the two compression springs are correspondingly disposed between the two connecting shafts 412 and the connecting seat body 21, that is, the compression springs and the tension springs are disposed on two opposite sides of the connecting shafts 412, and the compression directions (installation directions) of the two compression springs are consistent with the extending direction of the first groove 13. When the user pulls the two holding arms 1 apart, the compression spring is compressed to generate an outward extending stretching force, and when the user releases the two holding arms 1, the compression spring pushes the connecting shaft 412 to move inward until reaching a size suitable for the massaged part (for example, neck, abdomen, limbs, head, etc.) of the user.

The above describes that the elastic ring 5, the tension spring and the pressure spring are only provided with one, and it should be noted that the adjusting mechanism may include two or three of the elastic ring 5, the tension spring and the pressure spring, that is, the elastic ring 5, the tension spring and the pressure spring may be simultaneously provided, the elastic ring 5 and the tension spring may also be simultaneously provided, or the elastic ring 5 and the pressure spring may be simultaneously provided, or the tension spring and the pressure spring may be simultaneously provided.

In addition, under the condition that the connecting shaft 412 is directly and fixedly connected with the second cover 112 of the clamping arm 1, the elastic ring 5 may be sleeved outside the two rotating shafts 12, the tension spring may be connected between the two connecting shafts 412, and the two tension springs are correspondingly arranged between the two rotating shafts 12 and the connecting seat body 21.

In one embodiment, when the massager is in the unfolding state, the distance X (clamping distance) between the two clamping arms 1 is greater than or equal to 45 mm and less than or equal to 75 mm, and the distance X (clamping distance) between the two clamping arms 1 refers to the minimum distance between the two clamping arms 1. Of course, different clamping intervals X can be set according to different using positions of the massager.

It should be noted that, when the massager is changed from the unfolded state to the folded state, the two holding arms 1 need to be pulled apart by a certain distance to both sides to avoid the mutual interference between the two holding arms 1; then the two holding arms 1 are forcibly turned.

In order to change the massager from the unfolded state to the folded state without pulling the two holding arms 1 apart by a certain distance, one end of the holding arm 1 close to the other holding arm 1 can be set to be in the shape of a circular arc with the central axis of the rotating shaft 12 as the central axis, so that the two holding arms 1 can be prevented from interfering with each other.
