[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present invention.

[0027] like Figure 1As shown, the utility model provides a massager with adjustable kneading width, comprising a housing 1, a driving mechanism and a transmission mechanism disposed within the housing 1, the transmission mechanism comprising a rotating shaft and a pair of cams symmetrically disposed on the rotating shaft, each cam being provided with a first swing arm 2, which is an existing structure and the specific working principle will not be elaborated herein;

[0028] like Figure 2-Figure 5 As shown, each first swing arm 2 is rotatably provided with a cross bar 7, and both ends of the cross bar 7 are provided with a first massage head 8. The massager also includes a fixing assembly for positioning and fixing the cross bar 7;

[0029] By rotating the cross bars 7 on the two first swing arms 2 and fixing the positions of the two cross bars 7 by the fixing assembly after rotating to a certain angle, the distance between the first massage heads 8 on the two cross bars 7 is adjusted, which to a certain extent expands the adjustment range of the first massage heads 8 on the two cross bars 7. In this way, the massager can be adjusted for use according to the width of the necks of people of different body shapes, thereby meeting the needs of different people for the most comfortable massage effect.

[0030] Preferably, the first massage head 8 is rotated and arranged on the cross bar 7. When performing massage, the friction between the first massage head 8 and the skin can be reduced, the risk of friction and skin breakage during massage can be avoided, and the comfort of massage can be improved.

[0031] like Figure 2-Figure 7 As shown, the fixing assembly includes a fixed shaft rod 4, a sleeve rod 9, an elastic member 6 (the elastic member 6 here can be set as a spring) and a block 5. The sleeve rod 9 is fixedly installed at the center position of the side wall of the cross bar 7. The bottom end of the sleeve rod 9 is provided with a bottom groove 91, and the top end of the sleeve rod 9 is provided with a top groove 93 connected to the bottom groove 91. The side wall of the top groove 93 is provided with at least two side grooves 92 for accommodating the block 5. The support seat 21 is fixedly installed on the first swing arm 2, and the support seat 21 is provided with a fixed shaft rod 4. The central axis of the cross bar 7 does not intersect with the central axis of the fixed shaft rod 4 (that is, the cross bar 7 and the fixed shaft rod 4 are eccentrically arranged. The cross bar 7 and the fixed shaft rod 4 are eccentrically arranged here). The arrangement includes but is not limited to the following two situations: one is that the central axis of the fixed shaft rod 4 coincides with the central axis of the sleeve rod 9, the sleeve rod 9 rotates around the central axis, and the central axis of the sleeve rod 9 does not intersect with the central axis of the cross bar 7; the other is that the central axis of the fixed shaft rod 4 does not coincide with the central axis of the sleeve rod 9, the sleeve rod 9 rotates eccentrically and is arranged on the periphery of the fixed shaft rod 4, and the central axis of the sleeve rod 9 intersects with the central axis of the cross bar 7); at least one clamping block 5 is provided on the side surface of the top end of the fixed shaft rod 4, an elastic member 6 is sleeved on the periphery of the fixed shaft rod 4, the sleeve rod 9 is sleeved on the periphery of the elastic member 6, one end of the elastic member 6 is fixed on the support seat 21, and the other end of the elastic member 6 abuts against the inner wall of the bottom groove 91;

[0032] Example 1: Here, two symmetrically arranged blocks 5 and two side grooves 92 are used as an example, and the cross bar 7 and the fixed shaft 4 are eccentrically arranged. In this case, by adjusting the cross bar 7 and rotating it 180 degrees, the distance between the first massage heads 8 on the two cross bars 7 can be switched to two states. The specific working principle of the fixing assembly is as follows:

[0033] By pressing one or two cross bars 7 to move closer to the shell 1, the sleeve rod 9 drives the elastic member 6 to compress until the block 5 is completely out of the side groove 92, thereby rotating the cross bar 7 180°. Then the cross bar 7 is released, and the elastic member 6 rebounds and resets, driving the sleeve rod 9 and the cross bar 7 to move away from the shell 1 until the two blocks 5 enter the side groove 92 again (the positions of the side grooves 92 entered by the two blocks 5 are swapped). Since the cross bar 7 is eccentrically arranged with the fixed shaft rod 4, the distance between the two cross bars 7 will change after one or two cross bars 7 are rotated 180° and fixed, which expands the adjustment range between the first massage heads 8 on the two cross bars 7 to a certain extent. In this way, the massager can be adjusted for use according to the width of the necks of people of different body shapes, thereby meeting the needs of different people for the most comfortable massage effect.

[0034] Example 2: Figure 8 As shown, at least one sector-shaped area is selected in the circumferential area of ​​the top groove 93, two side grooves 92 are equidistantly arranged in the sector-shaped area, and at least one clamping block 5 is arranged. Figure 8 Taking two symmetrically arranged fan-shaped areas as an example, two symmetrical blocks 5 are set, and the central angle of each fan-shaped area is 60°. The specific rotation adjustment and fixing method is the same as above and will not be repeated here. In this way, the adjustment range between the first massage heads 8 on the two cross bars 7 can be expanded to a certain extent. It should be noted that the eccentric setting of the cross bar 7 and the fixed shaft rod 4 is not limited here.

[0035] Example 3: Figure 9 As shown, in order to meet different needs, at least one sector-shaped area is selected in the circumferential area of ​​the top groove 93, and three side grooves 92 are equidistantly arranged in the sector-shaped area, and at least one clamping block 5 is provided. Figure 9 Taking two symmetrically arranged fan-shaped areas as an example, two symmetrical blocks 5 are set, and the central angle of each fan-shaped area is 90°. The specific rotation adjustment and fixing method is the same as above and will not be repeated here. In this way, the adjustment range between the first massage heads 8 on the two cross bars 7 can be expanded to a certain extent. It should be noted that the eccentric setting of the cross bar 7 and the fixed shaft 4 is not limited here.

[0036] The specific number of the side grooves 92 and the equally spaced spacing include but are not limited to the above arrangements.

[0037] like Figure 4 、 Figure 5 、 Figure 8 and Figure 9 As shown, the fixed shaft rod 4 is detachably fixed to the support base 21, and the clamping block 5 is detachably fixed to the fixed shaft rod 4;

[0038] By detachably fixing the block 5 to the fixed shaft rod 4, it can be disassembled as needed. On the one hand, it is convenient to replace the sleeve rod 9 (i.e., the cross bar 7) with side grooves 92 of different numbers and spacings to meet the different needs of different people. Secondly, it is convenient for the production and transportation of each component, and the overall assembly is relatively convenient. Thirdly, the inner wall of the bottom groove 91 not only squeezes the elastic part 6, but also when the sleeve rod 9 rotates, the elastic part 6 will be subjected to a circular rotation force. When the elastic part 6 is used for too long, it may cause the elastic part 6 to deform and twist and eventually fail to achieve the reset function. At the same time, the elastic part 6 can also be disassembled and replaced.

[0039] like Figure 2-Figure 7 As shown, an avoidance groove 71 is provided on the cross bar 7 (by providing the avoidance groove 71, when the cross bar 7 is pressed to move close to the housing 1, the block 5 can completely disengage from the side groove 92 to make way, thereby ensuring the normal rotation of the cross bar 7), the avoidance groove 71 is connected to the top groove 93 and the side groove 92, the top surface of the support seat 21 is fixedly installed with the vertical rod 3, the top of the vertical rod 3 is provided with a threaded rod 11, the fixed shaft rod 4 is located outside the vertical rod 3, the top surface of the fixed shaft rod 4 is provided with a top plate 51, the top plate 51 has a block 5 fixed to the outer edge of at least one side, the threaded rod 11 passes through the fixed shaft rod 4 and the top plate 51, the threaded rod 11 is threadedly connected to the nut 10, and the nut 10 is in contact with the top plate 51;

[0040] The specific method of fixing the clamping block 5 to the fixed shaft rod 4 is as follows: after the fixed shaft rod 4 is sleeved on the vertical rod 3, the sleeve rod 9 is sleeved on the outer periphery of the fixed shaft rod 4, the top plate 51 is placed on the top surface of the fixed shaft rod 4, the clamping block 5 is aligned with the side groove 92, and the fixed shaft rod 4 and the top plate 51 are both passed through the threaded rod 11, and then the nut 10 is screwed on the threaded rod 11 until the nut 10 is pressed tightly against the top surface of the top plate 51, thereby completing the assembly of the clamping block 5, the sleeve rod 9 and the cross bar 7;

[0041] On the contrary, when disassembling, loosen the nut 10, take out the block 5 and the top plate 51, and then complete the replacement of the sleeve rod 9 with side grooves 92 of different numbers and spacings. At the same time, when the elastic member 6 is deformed and twisted and ultimately cannot achieve the reset function, the elastic member 6 can also be disassembled and replaced.

[0042] like Figure 1 and Figure 2 As shown, it also includes a protective shell 12, which is arranged on the periphery of the cross bar 7 and the sleeve bar 9;

[0043] By providing the protective shell 12, impurities can be prevented from entering the side groove 92, thereby avoiding the situation where the block 5 cannot enter the side groove 92, and ensuring normal adjustment of the position of the cross bar 7, namely the first massage head 8.

[0044] like Figure 1 and Figure 2 As shown, the protective shell 12 includes two detachably fixedly connected half shells 121;

[0045] Specifically, the two half shells 121 can be fixed by screws or clamping, so that when the top plate 51 and the block 5 need to be replaced or when the first massage head 8 is damaged and needs to be replaced, the protective shell 12 can be quickly disassembled first, and then the nut 10 can be loosened, so as to facilitate the disassembly and replacement of the top plate 51 and the block 5, and at the same time facilitate the disassembly of the cross bar 7, the first massage head 8 and the elastic part 6.

[0046] like Figure 1 As shown, each cam is provided with a second swing arm 13, and one end of the second swing arm 13 is provided with a second massage head 15;

[0047] By arranging the second swing arm 13 and the second massage head 15, when the driving mechanism drives the transmission mechanism to move, the second massage head 15 can massage the shoulders. The specific traditional principle is the existing technology, thereby forming a massager that can massage the shoulders and neck of a person at the same time.

[0048] like Figure 1 As shown, the second massage head 15 is made of plastic, and the second massage head 15 is provided with a damped rotation at one end of the second swing arm 13. A soft rubber part 14 is provided on one side of the second massage head 15. The soft rubber part 14 is softer than other plastic parts of the second massage head 15. Therefore, according to people's needs, the second massage head 15 can be rotated so that the soft rubber part 14 or the plastic part of the second massage head 15 is facing the person's shoulder, so that people with different force requirements can choose to massage the plastic part or the soft rubber part 14.

[0049] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
