[0022] Please refer to Figures 1 to 3 The utility model provides a technical scheme: a stroke-adjustable fascia gun, which comprises a gun body 1 and a stroke adjustment assembly 2 located in the inner cavity of the gun body 1, the outer part of one end of the gun body 1 is provided with a massage head, and the stroke adjustment assembly 2 is used for adjusting the stroke of the reciprocating movement of the massage head.

[0023] In this technical solution, the stroke adjustment assembly 2 includes a reciprocating rod 21 and a turntable 22. The reciprocating rod 21 is axially slidably connected inside the gun body 1, and a lever 211 is fixedly connected to one side of it. One end of the reciprocating rod 21 is fixedly connected to the massage head via a connecting shaft. When the reciprocating rod 21 moves linearly back and forth, it drives the massage head to move linearly back and forth. The turntable 22 is located on one side of the lever 211, and a lever shaft 221 is radially slidably connected to one side of it. In a specific implementation, a groove can be opened on the surface of the turntable 22, and then a guide block that is slidably connected to the groove can be welded to one side of the lever shaft 221. The lever shaft 221 and the lever 211 are slidably connected, and the sliding direction is perpendicular to the reciprocating rod 21. Preferably, a slide rail 2111 is opened through one side of the lever 211, and a slider 2211 that is slidably connected to the slide rail 2111 is sleeved on the lever shaft 221. A rear bearing is provided between the slider 2211 and the lever shaft 221. When the dial 221 is fixed relative to the turntable 22, and the turntable 22 is controlled to rotate, the revolution of the dial 221 will drive the reciprocating rod 21 to reciprocate through the lever 211.

[0024] The stroke adjustment assembly 2 includes a limiting plate 23 and an adjusting shaft 24. The limiting plate 23 is coaxially disposed on one side of the turntable 22, and an elliptical groove 231 is formed on one side of the turntable 22 to roll and engage with the pivot shaft 221. Preferably, in a specific implementation, a roller 2212 is fitted onto the free end of the pivot shaft 221, abutting against the inner wall of the elliptical groove 231. The limiting plate 23 is rotatably connected to the inner cavity of the gun body 1. When the turntable 22 rotates, it drives the pivot shaft 221 to move along the elliptical groove 231. Controlling the rotation of the limiting plate 23 can drive the elliptical groove 231 to rotate, thereby changing the reciprocating stroke of the reciprocating rod 21. The adjusting shaft 24 is rotatably connected to the gun body 1 and is used to control the rotation of the limiting plate 23.

[0025] Specifically, a worm gear 241 is fixedly sleeved on one end of the adjusting shaft 24, and a coaxial worm wheel 232 is fixedly sleeved on one side of the limiting plate 23. The worm wheel 232 meshes with the worm gear 241. When the adjusting shaft 24 rotates, it can drive the worm wheel 232 to rotate through the worm gear 241, which in turn drives the limiting plate 23 to rotate. It also has stepless stroke adjustment and adjustment self-locking functions. One end of the adjusting shaft 24 extends to the outside of the gun body 1 and is fixedly connected to an adjusting head 242. The adjusting head 242 is a component for manually controlling the rotation of the adjusting shaft 24.

[0026] In this embodiment, a support shaft 11 is fixedly connected to the inner wall of the gun body 1, and a positioning sleeve 233 is fixedly provided in the middle of the limiting plate 23, which is sleeved outside the support shaft 11. The positioning sleeve 233 is rotatably connected to the support shaft 11. A limiting sleeve 222 is fixedly connected to the middle of the other side of the turntable 22, and a limiting shaft 12 is fixedly connected to the inner wall of the gun body 1 and rotatably connected to the limiting sleeve 222. The turntable 22 and the limiting plate 23 are coaxially supported by the support shaft 11 and the limiting shaft 12, respectively. This arrangement can improve the strength of the rotational support for the turntable 22 and the limiting plate 23.

[0027] Further, the other side of the rotating disc 22 is fixedly connected with coaxial transmission gear 223, in use, a driving motor can be installed in the inner cavity of the gun body 1, a passive gear meshing with the transmission gear 223 is fixedly installed on the output shaft of the driving motor, and the driving motor provides driving force for the rotation of the rotating disc 22.

[0028] Working principle: the rotating disc 22 is controlled to rotate, the rotating disc 22 drives the sun gear 221 to revolve, and the sun gear 221 moves along the elliptical groove 231, at this time, the sun gear 221 drives the reciprocating rod 21 to move linearly through the push rod 211, and then drives the massage head to move linearly, when it is needed to adjust the stroke of the massage head, the adjusting shaft 24 is manually driven to rotate through the adjusting head 242, the worm 241 drives the worm wheel 232 to rotate, and then drives the limiting disc 23 to rotate, at this time, the elliptical groove 231 rotates, and the sun gear 221 directly changes the reciprocating stroke of the reciprocating rod 21 under the limitation of the elliptical groove 231, and can be adjusted steplessly to be larger or smaller.

[0029] In addition, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the specification is described in this way only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.
