[0002] In the prior art, a Chinese utility model patent application with number 202323218600.9 discloses an adjustable-width massager, including two massage components, a rotating shaft, a housing, and an adjustable-width component. Each massage component includes a massage element, a first threaded component, and a second threaded component. The first threaded component is rotatably connected to the massage element. The second threaded component includes a threaded portion and a connecting portion, with the threaded portion screwed into the first threaded component. The rotating shaft passes through the two massage components. The housing has a first accommodating groove and two first accommodating cavities that are interconnected. A connecting portion is provided in... Within a first accommodating cavity, the distance adjustment assembly includes a transmission sleeve and a torsion member disposed within a first accommodating groove. The torsion member can rotate around a central axis and is connected to the housing. The inner surface of the transmission sleeve abuts against the circumferential surface of the torsion member and the connecting part. The transmission sleeve is disposed within the first accommodating groove and the first accommodating cavity. By rotating the torsion member, the width distance between the two sets of massage components can be changed. However, this adjustment method requires manually tightening the torsion member. When the torsion member is too tight, a large force is required. When the torsion member is too loose, the stability is poor, and the adjustment is inconvenient. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0013] This utility model discloses an adjustable neck massage mechanism, including a housing 1. The housing 1 is provided with a kneading arm 2, a massage arm 3, and a drive mechanism for driving the kneading arm 2 and the massage arm 3. The drive mechanism includes a massage motor 41 mounted on the housing 1, a rotating shaft 42 rotatably mounted on the housing 1 and linked with the massage motor 41, and an eccentric wheel 43 mounted on the rotating shaft 42. The eccentric wheel 43 is provided with a first mounting part 431 and a second mounting part 432. The first mounting part 431 is linked with the kneading arm 2, and the kneading arm 2 is sleeved on the rotating shaft 42. The housing 1 is also provided with a guide groove 5 arranged along the length direction of the rotating shaft 42. The kneading arm 2 is provided with a guide member 6 that slides within the guide groove 5. A transmission arm 7 is sleeved on the second mounting part 432. The massage arm 3 is oscillatingly mounted on the housing 1 and is linked with the transmission arm 7. The kneading arm 2, the massage arm 3, and the eccentric wheel 43 are all provided in two sets. The housing 1 is provided with clearance holes for the kneading arm 2 to swing and slide relative to each other, which is a conventional technical means and will not be described in detail here. In addition, a rubber sleeve can be provided on the clearance hole, which can be waterproof and reduce noise. In this utility model embodiment, the rotating shaft 42 is provided with a slide 8, a swing arm 9 that drives the slide 8 to slide axially along the rotating shaft 42, and an adjustment motor 10 that drives the swing arm 9 to swing. The kneading arm 2 is axially and synchronously circumferentially mounted on the slide 8, and the side of the kneading arm 2 facing the first mounting part 431 is provided with a matching insertion hole 20. The first mounting part 431 can be inserted into or partially pulled out of the insertion hole 20.

[0014] Using the above technical solution, during use, the massage motor 41 drives the rotating shaft 42 to rotate, which in turn drives the eccentric wheel 43 to rotate. The first mounting part 431 drives the kneading arm 2 to perform kneading massage. At the same time, the transmission arm 7 pushes and pulls the massage arm 3 to achieve massage. When the user feels that the width of the two sets of kneading arms 2 is too wide or too narrow, the motor 10 is adjusted to make the swing arm 9 swing, thereby driving the slide 8 to slide along the axis of the rotating shaft 42, thereby adjusting the distance between the two sets of kneading arms 2. It adopts electric adjustment, which is convenient and stable during adjustment. The insertion hole 20 can play a role in avoiding obstacles when it is close to the first mounting part 431. The rotation of the first mounting part 431 can squeeze the inner wall of the insertion hole 20, and the kneading massage is achieved through the cooperation of the guide 6 and the guide groove 5.

[0015] The swing arm 9 includes a movable end 91 that drives the slide block 8 to slide, a hinged end 92 that is hinged to the housing 1, and a linkage end 93 that cooperates with the adjusting motor 10. A connecting rod 30 is hinged to the linkage end 93. A threaded hole 40 is provided on the connecting rod 30. A screw 50 that is threaded into the threaded hole 40 is passed through the threaded hole 40. The screw 50 is linked with the adjusting motor 10. The connecting rod 30 is extended and retracted by the cooperation of the screw 50 and the threaded hole 40. This not only makes the adjustment more precise, but also makes the use more stable. Preferably, the threaded hole 40 is formed by providing a nut on the connecting rod.

[0016] The movable end 91 is provided with a long slot 911, and the slide block 8 is provided with a transmission block 60 corresponding to the position of the long slot 911. The transmission block 60 is inserted into the long slot 911 and abuts against its inner wall, and can slide along the length direction of the long slot 911. The long slot 911 can increase the amount of adjustment displacement and prevent hard collision, thereby increasing the service life of the product.

[0017] The slide block 8 includes a first seat 81 and a second seat 82, which are set separately. An arc-shaped groove is provided between the first seat 81 and the second seat 82. The two arc-shaped grooves cooperate to form an annular hole 83. The kneading arm 2 is provided with a locking block 70 corresponding to the position of the annular hole 83. The locking block 70 abuts against the inner wall of the annular hole 83 and can rotate along the annular hole 83. The separate setting makes it easy for the locking block 70 of the kneading arm 2 to be assembled into the annular hole 83, and the mold is also more convenient to demold.

[0018] The transmission block 60 is provided with an anti-detachment edge 601 on its outside. The diameter of the anti-detachment edge 601 is larger than the short side diameter of the long slot 911, which can prevent the transmission block 60 from detaching from the long slot 911, making the slide 8 more stable when pushed and pulled.

[0019] One end of the long slot 911 is connected to an assembly hole 912 for inserting the transmission block 60. The diameter of the assembly hole 912 is greater than or equal to the anti-detachment edge 601 and is integrated with the long slot 911. This facilitates the assembly of the transmission block 60 into the long slot 911, and the normal driving distance will not drive the transmission block 60 to the top of the long slot 911. Therefore, the layout is also relatively reasonable.
