The following detailed description is made with reference to the accompanying drawings.
Example one
Referring to fig. 1 and 2, fig. 1 is a schematic perspective view of a neck massager in the present embodiment, and fig. 2 is a schematic perspective view of the neck massager of the present invention with the clamping arms removed from the shell. The neck massager in this embodiment comprises a middle bracket 10, a component 50 and two clamping arms 20.
Wherein, middle support 10 is the setting of C font, and this C font middle support 10 has elasticity, and C font structure and neck shape looks adaptation. Two clamping arms 20 are respectively arranged at two ends of the middle support 10, each of the two clamping arms 20 includes a first main body section 21 (a portion of the clamping arm 20 located in the dashed line frame at the upper side in fig. 1) and a second main body section 22 (a portion of the clamping arm 20 located in the dashed line frame at the lower side in fig. 1), the first main body section 21 is closer to the middle support 10 than the second main body section 22, and the thickness and/or width of at least one of the first main body section 21 and the second main body section 22 in the direction away from the middle support 10 gradually increases to prevent the fingers of the user from sliding towards the direction away from the middle support 10.
Specifically, when the thickness of the first body segment 21 in the direction away from the middle support 10 gradually increases, no matter the finger grips the clamping arm 20 from the width direction or from the thickness direction, the outer surface of the first body segment 21 may expand at the position where the thickness of the first body segment 21 is larger, and at this time, the outer surface of the first body segment 21 can apply friction and blocking force to the finger toward the middle support 10, so as to prevent the finger of the user from sliding toward the direction away from the middle support 10.
When the width of the first body segment 21 in the direction away from the middle support 10 gradually increases, no matter the fingers hold the clip arm 20 from the width direction or from the thickness direction, at the position where the width of the first body segment 21 is larger, the outer surface of the first body segment 21 may expand outward, and at this time, the surface of the first body segment 21 can apply friction and blocking force towards the middle support 10 to the fingers, so as to prevent the fingers of the user from sliding towards the direction away from the middle support 10.
When the width and the thickness of the first body segment 21 in the direction away from the middle support 10 are gradually increased, no matter the fingers hold the clamping arm 20 from the width direction or the thickness direction, at the position where the width and the thickness of the first body segment 21 are larger, the outer surface of the first body segment 21 is expanded, and at this time, the outer surface of the first body segment 21 can apply friction and blocking force towards the middle support 10 to the fingers, so that the fingers of the user are prevented from sliding towards the direction away from the middle support 10.
Similarly, the thickness and width of the second body segment 22 increase gradually in the direction away from the middle support 10, and the outer surface of the second body segment 22 expands outward at the position where the thickness and width of the second body segment 22 increase, and at this time, the outer surface of the second body segment 22 can apply friction and blocking force to the fingers toward the middle support 10, so as to prevent the fingers of the user from sliding in the direction away from the middle support 10.
It can be seen that, because the thickness and/or the width of the first body section 21 of the clamping arm 20 in the direction away from the middle bracket 10 are gradually increased, in the process of actual use, a user can hold the first body section 21 by hand, and the first body section 21 can apply certain friction and blocking force to the hand of the user, so that the hand of the user can be prevented from sliding off the clamping arm 20, the user can conveniently grip the neck massager, and the user experience is good.
It should be understood that the thickness of the clip arms 20 in this embodiment refers to the distance between the inner and outer edges of the neck massager, and the width of the clip arms 20 in this embodiment refers to the distance between the upper and lower edges of the clip arms 20 when the neck massager is placed horizontally (the middle support and the clip arms are both in contact with the horizontal plane).

Due to the volume expansion part, the accommodating space 23 on the clamping arm 20 can be correspondingly set to be larger, and when the neck massager is actually installed, the components 50 and the like can be installed in the accommodating space 23. Meanwhile, because the front end of human neck both sides down extends with the shoulder neck junction, the lower jaw up extends, demonstrates the tubaeform that expands gradually, has the arm lock 20 of volume expansion portion through the setting, under the prerequisite of guaranteeing that arm lock 20 not take place to interfere with human shoulder neck and lower jaw, the volume that can increase accommodation space 23 on arm lock 20 as far as possible can make the counter weight of neck massager keep on arm lock 20, will as the user the utility model discloses a neck massager wears when the neck, can produce the power that the slant descends, can form flagging sense, and then can avoid neck massager to follow the neck landing.
Further, the middle support 10 in this embodiment is provided with a massage component 11, the massage component 11 protrudes out of the inner side surface of the middle support 10, and when the neck massager works, the neck of the human body is massaged through the massage component 11, so that the cell metabolism is improved, the microcirculation is improved, and the cervical discomfort is relieved. The middle bracket 10 has elasticity, which facilitates the opening or contraction of the two clamping arms 20, and has a simple structure and is convenient for users to use.
In an alternative embodiment of the present invention, the cross-sectional area of the first main body section 21 is gradually increased in the direction away from the middle support 10, so as to ensure the integrity of the appearance of the clamping arm 20, and the change is not abrupt, thereby avoiding the sharp edge or acute angle formed on the surface of the clamping arm 20, and avoiding the bad touch feeling when the user is scratched or in contact with the user.
