[0004] The technical solution adopted by the utility model to achieve its purpose is: a reciprocating swing structure of a massage head of a massage stick, comprising a massage stick main body and a massage head, the massage stick main body having a main body inner shell, a push-pull driving device and a push-pull rod connected to the push-pull driving device installed in the main body inner shell, and the push-pull rod axially passes through the main body inner shell and is connected to the massage head; the massage head has a massage head inner shell, the end of the massage head inner shell forms a rotatable pivot connection with the end of the main body inner shell, and the end of the massage head inner shell is also provided with a connecting block, the connecting block is provided with a strip connecting hole that is inclined at an axial angle to the push-pull rod, and the outer end of the push-pull rod is driven and connected to the connecting block by a connecting shaft that vertically passes through the strip connecting hole.

[0005] The two sides of the connecting end of the main body inner shell extend axially to form a pair of parallel first pivot walls. Correspondingly, the connecting end of the massage head inner shell also extends axially to form a pair of parallel second pivot walls. The second pivot walls are pivotally connected to the first pivot walls through pivot axes, and the second pivot walls are located on the inner side of the first pivot walls, so that the massage head inner shell can rotate around the pivot axis; the outer end of the push-pull rod and the connecting block are both arranged between the second pivot walls, and a connecting groove for the connecting block to penetrate and move is provided at the outer end of the push-pull rod.

[0006] The ends of the inner shell of the massage head and the ends of the connecting block are both in arc shape.

[0007] The push-pull driving device is a push-pull electromagnet or a telescopic motor.

[0008] The utility model is used in a massage stick, and is equipped with lithium batteries, switches and other components, and is encapsulated by a silicone shell to form an integral massage stick, which can achieve a swinging massage effect of the massage head when in use. The utility model has a simple structure, low cost, and has light and heavy massage power transmission, which has a better massage effect. Description of the drawings:

[0011] Figure 3 It is a partial cross-sectional view of the utility model. Specific implementation method:

[0012] The utility model is further described below in conjunction with specific embodiments and drawings.

[0013] like Figure 1-Figure 3 As shown, the utility model is a reciprocating swing structure of a massage head of a massage stick, comprising a massage stick body 1 and a massage head 2, the massage stick body 1 having a main body inner shell 11, a push-pull drive device 12 and a push-pull rod 13 connected to the push-pull drive device 12 are installed in the main body inner shell 11, and the push-pull rod 13 axially passes through the main body inner shell 11 and is connected to the massage head 2; the massage head 2 has a massage head inner shell 21, the end of the massage head inner shell 21 is rotatably pivoted with the end of the main body inner shell 11, and the end of the massage head inner shell 21 is also provided with a connecting block 22, the massage head inner shell 21 is a hollow structure, and one end of the connecting block 22 is fixedly inserted in the massage head inner shell 21; the The connecting block 22 is provided with a strip-shaped connecting hole 221 which is inclined at an axial angle to the push-pull rod 13, and the outer end of the push-pull rod 13 is driven and connected to the connecting block 22 by a connecting shaft 131 which vertically passes through the strip-shaped connecting hole 221; when the push-pull driving device 12 is working, its output end causes the push-pull rod 13 to move, and the connecting shaft 131 at the outer end of the push-pull rod 13 also moves axially, and under the joint action of the oblique strip-shaped connecting hole 221 and the pivot connection between the massage head inner shell 21 and the main body inner shell 11, the connecting block 22 and the massage head inner shell 21 connected thereto rotate and swing around their pivot axis, so that the entire massage head 2 swings back and forth relative to the massage stick main body 1, thereby achieving a swinging massage effect;

[0014] The internal space of the main body inner shell 11 is designed to be stepped along the length direction to adapt to the shape of the push-pull drive device 12 and the push-pull rod 13, thereby reducing the volume;

[0015] The two sides of the connecting end of the main body inner shell 11 extend axially to form a pair of parallel first pivot walls 111. Correspondingly, the connecting end of the massage head inner shell 21 also extends axially to form a pair of parallel second pivot walls 211. The second pivot wall 211 is pivoted to the first pivot wall 111 through a pivot shaft 112. The pivot shaft 112 is formed on the inner side of the first pivot wall 111, and the second pivot wall 211 is located on the inner side of the first pivot wall 111, so that the massage head inner shell 21 can rotate around the pivot shaft 112; the outer end of the push-pull rod 13 and the connecting block 22 are both arranged between the second pivot walls 211, and a connecting groove 132 is provided at the outer end of the push-pull rod 13 for the connecting block 22 to penetrate and move; the push-pull rod 13 and the connecting block 22 form power transmission and limit the swing direction and swing angle through the connecting shaft 131 and the oblique strip connecting hole 221.

[0016] The ends of the massage head inner shell 21 and the ends of the connecting block 22 are both in arc shape, so as to realize rotation and swing without interfering with the main body inner shell 11 and the push-pull rod 13.

[0017] The push-pull driving device 12 is a push-pull electromagnet or a telescopic motor. These components have simple structures, low costs, low working noise, small vibration, and long service life.

[0018] The outer wall of the main body inner shell 11 is also formed with protruding reinforcing ribs 113, which can not only strengthen the structural strength of the main body, but also better position it during silicone packaging.

[0019] The reciprocating swing structure of the utility model is used in a massage stick, and is matched with lithium batteries, switches and other components (omitted in the figure), and is encapsulated by a silicone shell to form an integral massage stick, which can achieve the swinging massage effect of the massage head when used. The utility model has a simple structure and low cost, and the massage power transmission is light and heavy, and the massage effect is better.
