[0054] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this application. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this application.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0056] Massage devices, as health care tools to relieve or eliminate physical fatigue, are becoming increasingly popular due to their flexibility and convenience. To achieve better massage effects, targeted massage devices are often designed based on the structural characteristics of different parts of the body, such as neck massagers, waist massagers, and shoulder and neck massagers. Currently, there are numerous types and brands of massage devices available, offering consumers a wide range of choices. Therefore, how to win consumer favor and enhance product competitiveness has become an increasingly important issue for massage device manufacturers.

[0057] Nowadays, people are increasingly working and living in situations where they sit for long periods of time. In order to eliminate or alleviate discomfort, people often use massage devices to massage the uncomfortable areas to relieve fatigue.

[0058] However, in related technologies, massage devices often have a single massage position when massaging users, which cannot be adjusted according to the user's needs. This reduces the user's comfort and lowers the user experience.

[0059] Based on this, the present disclosure provides a transmission component 300 that can adjust the massage position according to user needs, thereby improving the user experience.

[0060] To better understand the transmission component 300 of this disclosure, the following description will be based on the adjustment device 10 and the massage device 1 in which the transmission component 300 is applied.

[0061] like Figures 1 to 4 As shown, in some embodiments, a massage device 1 is provided, which includes an adjustment device 10, a massage component 20, and a second drive mechanism 30. The adjustment device 10 includes a support component 100, a first drive mechanism 200, and a transmission component 300.

[0062] Combination Figure 1 As shown, the transmission component 300 includes an adjustment assembly 310 and a transmission assembly 320. The adjustment assembly 310 includes a first adjustment member 311 and a second adjustment member 312 spaced apart from the first adjustment member 311. The transmission assembly 320 includes a rotating shaft 321 rotatably disposed on the first adjustment member 311, a driving member 322 rotatably connected to the rotating shaft 321, and a connecting rod 323 rotatably connected to the second adjustment member 312. The second driving mechanism 30 is disposed on the bearing assembly 100 and is used to drive the rotating shaft 321 to rotate. The driving member 322 can rotate with the rotating shaft 321, and there is a first included angle between the driving member 322 and the rotating shaft 321. One end of the driving member 322 is rotatably connected to the rotating shaft 321, and the first rotation axis of the driving member 322 relative to the rotating shaft 321 is not coaxial with the second rotation axis of the rotating shaft 321. The other end of the driving member 322 is rotatably connected to the connecting rod 323. The driving member 322 is provided with a mounting portion 3221 for mounting the massage component 20. The massage component 20 is mounted on the drive component 322 via the mounting part 3221.

[0063] The first drive mechanism 200 is disposed on the bearing assembly 100. At least one of the first adjusting member 311 and the second adjusting member 312 is slidably connected to the bearing assembly 100 and is drively connected to the first drive mechanism 200 so that the distance between the first adjusting member 311 and the second adjusting member 312 can be adjusted through the first drive mechanism 200, so that the size of the first included angle can be adjusted.

[0064] Combination Figures 1 to 4As shown, the transmission component 300 drives the driving component 322 to rotate via a rotating shaft 321 rotatably mounted on the first adjusting component 311. A first included angle exists between the driving component 322 and the rotating shaft 321. The massage component 20 is mounted to the driving component 322 via a mounting portion 3221, so that the transmission component 320 drives the massage component 20 to rotate via the driving component 322 to achieve massage. When the adjusting device 10 and the massage device 1 are in use, the first driving mechanism 200 can drive at least one of the first adjusting component 311 and the second adjusting component 312 to slide relative to the supporting component 100, thereby adjusting the distance between the first adjusting component 311 and the second adjusting component 312. The other end of the drive member 322 is rotatably connected to the connecting rod 323, and the connecting rod 323 is rotatably connected to the second adjusting member 312. The first rotation axis of the drive member 322 relative to the rotation shaft 321 is not coaxial with the second rotation axis of the rotation shaft 321. By adjusting the distance between the first adjusting member 311 and the second adjusting member 312, the size of the first included angle can be adjusted, thereby adjusting the massage position of the massage device 1 to improve the user experience.

[0065] Understandably, by setting the first axis of rotation of the drive member 322 relative to the second axis of rotation of the rotation shaft 321 to be different axes, the first included angle between the drive member 322 and the rotation shaft 321 can remain unchanged during the process of the rotation shaft 321 rotating to drive the drive member 322. However, when the distance between the first adjusting member 311 and the second adjusting member 312 changes, the drive member 322 will rotate relative to the rotation shaft 321 along the first axis of rotation, so that the size of the first included angle is adjustable.

[0066] like Figure 5 as well as Figure 6 As shown, in some embodiments, the third rotation axis of the connecting rod 323 relative to the driving member 322 is not coaxial with the second rotation axis. Thus, when the second driving mechanism 30 drives the rotating shaft 321 to rotate to drive the driving member 322, the fact that the third rotation axis of the connecting rod 323 relative to the driving member 322 is not coaxial with the second rotation axis ensures that the first included angle between the driving member 322 and the rotating shaft 321 does not change. This prevents the massage position of the massage device 1 from constantly changing during the massage process, improving the reliability of the massage device 1 and enhancing the user experience. Furthermore, by rotatably connecting the connecting rod 323 to the driving member 322, when the first driving mechanism 200 drives at least one of the first adjusting member 311 and the second adjusting member 312 to move, the size of the first included angle can be adjusted.

[0067] It should be noted that, as Figure 1 In the diagram, axis a is the first axis of rotation, as shown. Figure 6 In the diagram, axis b is the second axis of rotation, as shown. Figure 1The axis c shown is the third axis of rotation.

[0068] like Figure 6 As shown, in some embodiments, the second adjusting member 312 includes a movable body 3121 and a rotating part 3122 rotatably disposed on the movable body 3121. The connecting rod 323 is rotatably connected to the rotating part 3122, and the rotation axis of the rotating part 3122 is coaxially arranged with the second rotation axis. Thus, the rotating part 3122 facilitates the rotatable connection between the connecting rod 323 and the second adjusting member 312. Furthermore, since the rotation axis of the rotating part 3122 is coaxial with the second rotation axis, the rotation of the driving member 322 is more stable, reducing wear and improving durability.

[0069] like Figure 2 As shown, in some embodiments, the massage assembly 20 includes a shoulder massager 21 and a neck massager 22. Thus, the shoulder massager 21 and neck massager 22 respectively massage the shoulders and neck of the human body.

[0070] Understandably, the massage component 200 can massage the neck, shoulders, back, waist, hips, or legs, and can be set according to actual needs.

[0071] like Figure 1 as well as Figure 7 As shown, in some embodiments, the mounting part 3221 includes an eccentric drive part 3222 for transmission connection with the shoulder massager 21. Thus, the shoulder massager 21 is mounted on the drive part 322 via transmission connection with the eccentric drive part 3222. The first drive mechanism 200 drives the rotating shaft 321 to rotate, and the drive part 322, which is transmission connection to the rotating shaft 321, drives the shoulder massager 21 to move synchronously, so as to massage the human shoulder using the shoulder massager 21. During the massage, the drive part 322 drives the eccentric drive part 3222 to rotate, causing the shoulder massager 21 to undergo eccentric motion. This allows the shoulder massager 21 to simulate the trajectory of a human hand kneading the shoulder, achieving a kneading massage of the human shoulder and enhancing the shoulder massage effect.

[0072] like Figure 7 As shown, in some embodiments, the drive member 322 includes a drive rod 3223 and an eccentric cam 3224 fixed on the drive rod 3223. The eccentric cam 3224 is provided with an eccentric drive portion 3222. In this way, the drive member 322 is formed by fixing the eccentric cam 3224 to the drive rod 3223, which can reduce the manufacturing difficulty of the drive member 322.

[0073] It should be noted that there are various ways to fix the drive rod 3223 and the eccentric cam 3224, including but not limited to snap-fit ​​fixing, screw fixing, riveting fixing, pin fixing, welding fixing, etc.

[0074] like Figure 8 as well as Figure 9 As shown, in some embodiments, the drive rod 3223 is provided with a limiting member 301. The limiting member 301 can protrude from the drive rod 3223 or be a groove on the drive rod 3223. Corresponding to the limiting member 301 protruding from the drive rod 3223, the eccentric cam 3224 is provided with a first mounting groove 302 and a limiting groove 303 communicating with the first mounting groove 302. The eccentric cam 3224 is sleeved on the drive rod 3223 through the first mounting groove 302. The limiting member 301 and the limiting groove 303 cooperate to restrict the rotation of the eccentric cam 3224 relative to the drive rod 3223. Corresponding to the groove on the drive rod 3223, the eccentric cam 3224 is provided with a first mounting groove 302 and a limiting block protruding from the inner wall of the first mounting groove 302. An eccentric cam 3224 is fitted onto a drive rod 3223 via a first mounting groove 302. The groove of the limiting member 301 engages with the limiting block to allow the eccentric cam 3224 to rotate relative to the drive rod 3223. The drive rod 3223 has a limiting portion that abuts against the eccentric cam 3224 to restrict its movement along the axis of the drive rod 3223. Thus, the engagement of the limiting member 301 and the limiting groove 303 ensures that the eccentric cam 3224 rotates synchronously with the drive rod 3223, thereby restricting its rotation relative to the drive rod 3223. The abutment between the limiting portion and the eccentric cam 3224 further restricts its movement along the axis of the drive rod 3223. Under the action of the limiting member 301 and the limiting portion, the eccentric cam 3224 is fixed to the drive rod 3223, a simple fixation method.

[0075] like Figure 8 as well as Figure 9 As shown, in some embodiments, the drive rod 3223 is provided with a mounting hole 304 that matches the limiting member 301, and the limiting member 301 is inserted into the drive rod 3223 through the mounting hole 304. Thus, the limiting member 301 is inserted into the drive rod 3223 through the mounting hole 304, protruding from the drive rod 3223, thereby enabling it to cooperate with the limiting groove 303. This implementation is simple and easy to carry out.

[0076] In one example, the limiting member 301 includes a pin that is inserted into the drive rod 3223 through a mounting hole 304.

[0077] like Figure 7As shown, in some embodiments, the eccentric cam 3224 is further provided with a protrusion 3225 adjacent to the eccentric drive unit 3222, and the transmission assembly 320 also includes a limiting ring 3226 fixedly connected to the eccentric cam 3224. The limiting ring 3226 and the protrusion 3225 are spaced apart to form a limiting structure that restricts the movement of the shoulder massage member 21 along the axial direction of the eccentric cam 3224. Thus, when the shoulder massage member 21 is assembled with the eccentric cam 3224, the shoulder massage member 21 is mounted on the eccentric drive unit 3222 and limited by the protrusion 3225. Then the limiting ring 3226 is fixed to the eccentric cam 3224 to form a limiting structure that restricts the movement of the shoulder massage member 21 along the axial direction of the eccentric cam 3224.

[0078] like Figure 7 As shown, in some embodiments, the mounting portion 3221 further includes a first connecting portion 3227 for rotatably connecting with the neck massager 22. Thus, by rotatably connecting with the neck massager 22 via the first connecting portion 3227, the neck massager 22 is mounted onto the drive member 322. When the second drive mechanism 30 drives the rotating shaft 321 to drive the drive member 322, the drive member 322 can drive the neck massager 22 to rotate.

[0079] It should be noted that there are various ways in which the first connecting part 3227 can be rotatably connected to the neck massager 22, including but not limited to bearing 3228 connection, bushing connection, etc.

[0080] like Figure 7 As shown in one example, the first connecting part 3227 includes a bearing 3228, and the neck massager 22 is rotatably connected to the mounting part 3221 via the bearing 3228.

[0081] like Figure 1 As shown, in some embodiments, at least one of the first adjusting member 311 and the second adjusting member 312 is slidably connected to the support assembly 100 and driveably connected to the first driving mechanism 200, so as to adjust the distance between the first adjusting member 311 and the second adjusting member 312 by means of the first driving mechanism 200. Thus, when the first adjusting member 311 is slidably connected to the support assembly 100 and driveably connected to the first driving mechanism 200, the first driving mechanism 200 can drive the movement of the first adjusting member 311 to adjust the distance between the first adjusting member 311 and the second adjusting member 312. Furthermore, moving the first adjusting member 311 via the first driving mechanism 200 is easy for the user to operate and improves the user experience.

[0082] And / or, when the second adjusting member 312 is slidably connected to the bearing assembly 100 and drive-connected to the first driving mechanism 200, the movement of the second adjusting member 312 can be achieved through the first driving mechanism 200 to adjust the distance between the first adjusting member 311 and the second adjusting member 312. Furthermore, achieving the movement of the second adjusting member 312 through the first driving mechanism 200 is easy for the user to operate and improves the user experience.

[0083] It should be noted that the first drive mechanism 200 can be implemented in various ways, including but not limited to power devices such as pneumatic cylinders, hydraulic cylinders, and linear motors that directly drive the first adjusting member 311 and / or the second adjusting member 312 to move, as well as telescopic mechanisms such as gear and rack mechanisms and lead screw and nut mechanisms that indirectly realize the telescopic movement of the first adjusting member 311 and / or the second adjusting member 312.

[0084] like Figure 1 As shown in one example, the first adjusting member 311 is fixed to the supporting assembly 100, and the second adjusting member 312 is slidably connected to the supporting assembly 100. The first driving mechanism 200 is used to drive the second adjusting member 312 to move, so that the size of the first included angle is adjustable. In this way, the first driving mechanism 200 drives the second adjusting member 312 to move, thereby adjusting the distance between the first adjusting member 311 and the second adjusting member 312, and thus adjusting the size of the first included angle.

[0085] like Figure 2 as well as Figure 10 As shown, in some embodiments, the bearing assembly 100 is provided with a fixing block 110 spaced apart from the first adjusting member 311, and the second adjusting member 312 is slidably disposed between the first adjusting member 311 and the fixing block 110. The first driving mechanism 200 includes a first power source 210 and a first screw 220. The first power source 210 is disposed on the bearing assembly 100 and is used to drive the first screw 220 to rotate. The two ends of the first screw 220 are rotatably connected to the fixing block 110 and the first adjusting member 311, respectively, and the second adjusting member 312 is threadedly connected to the first screw 220. Thus, the first drive mechanism 200 drives the first screw 220 to rotate via the first power source 210. The two ends of the first screw 220 are rotatably connected to the fixed block 110 and the first adjusting member 311, respectively. The first screw 220 is also threadedly connected to the second adjusting member 312. This allows the first drive mechanism 200 to drive the first screw 220 to rotate, thereby driving the second adjusting member 312 to slide, adjusting the distance between the first adjusting member 311 and the second adjusting member 312, and thus adjusting the size of the first included angle. Utilizing the self-locking characteristic of the thread, the second adjusting member 312 can be rotated and stopped instantly.

[0086] like Figure 4 as well as Figure 10As shown, in some embodiments, the first driving mechanism 200 further includes a first worm gear 230 that is pulverizedly connected to the first screw 220, and the first power source 210 is provided with a first worm 211 that is pulverizedly connected to the first worm gear 230. Thus, the first driving mechanism 200 drives the first worm 211 to rotate via the first power source 210, and the first worm 211 is pulverizedly connected to the first worm gear 230, which in turn is pulverizedly connected to the first screw 220, thereby driving the first screw 220 to rotate.

[0087] like Figure 1 as well as Figure 10 As shown, in some embodiments, the transmission component 300 includes two parts, symmetrically arranged on the support component 100. The first screw 220 includes two parts, each corresponding to one of the transmission components 300. The two first screws 220 have different thread directions and are respectively connected to the first worm gear 230. Thus, by symmetrically arranging two transmission components 300 on the support component 100 and correspondingly arranging the first screws 220, and by arranging massage components 20 on the driving members 322 of the transmission components 300, and by connecting the first worm gear 230 to the two first screws 220 with different thread directions, when the first driving component drives the second adjusting member 312, the second adjusting members 312 on both sides move towards or away from each other, thereby adjusting the position of the two massage components 20 to suit different users.

[0088] like Figure 1 as well as Figure 4 As shown, in some embodiments, the first adjusting member 311 and the second adjusting member 312 are slidably connected to the support assembly 100, and the first driving mechanism 200 is used to drive the first adjusting member 311 and the second adjusting member 312 to move, so that the size of the first included angle is adjustable. Thus, when it is necessary to adjust the size of the first included angle, the first driving mechanism 200 is used to drive the first adjusting member 311 and the second adjusting member 312 to move, thereby adjusting to the target included angle. Using the method of driving the first adjusting member 311 and the second adjusting member 312 makes the adjustment of the first included angle more flexible and faster.

[0089] like Figure 1 as well as Figure 10As shown, in some embodiments, the first driving mechanism 200 includes a first power source 210 and a first screw 220. The first power source 210 is disposed on the bearing assembly 100 and is used to drive the first screw 220 to rotate. The first screw 220 includes a first screw body 221 and a second screw body 222. A first adjusting member 311 is threadedly connected to the first screw body 221, and a second adjusting member 312 is threadedly connected to the second screw body 222. The threads of the first screw body 221 and the second screw body 222 have opposite directions of rotation. Thus, when the first screw 220 rotates, it can synchronously drive the first adjusting member 311 and the second adjusting member 312 to move towards each other or away from each other, thereby adjusting the distance between them. The distance adjustment speed is fast, thereby adjusting the first included angle.

[0090] And / or, such as Figure 1 as well as Figure 10 As shown, in some embodiments, the pitches of the first screw body 221 and the second screw body 222 are not equal. Thus, by utilizing the unequal pitches of the first screw body 221 and the second screw body 222, when the first screw 220 rotates, the first adjusting member 311 and the second adjusting member 312, which are respectively connected to the first screw body 221 and the second screw body 222, move at different speeds. This difference in speed allows for adjustment of the distance between the first adjusting member 311 and the second adjusting member 312, thereby adjusting the first included angle.

[0091] In some embodiments, the ratio of the pitch of the first screw body 221 to the pitch of the second screw body 222 is less than 1:1 and greater than or equal to 1:3.

[0092] It should be noted that the ratio of the pitch of the first screw body 221 to the pitch of the second screw body 222 can be implemented in various ways, including less than or equal to 1:1.2, less than or equal to 1:1.3, less than or equal to 1:1.4, less than or equal to 1:1.5, less than or equal to 1:2, less than or equal to 1:2.1, less than or equal to 1:2.2, less than or equal to 1:2.5, less than or equal to 1:2.6, less than or equal to 1:2.7, less than or equal to 1:2.8, less than or equal to 1:2.9, etc. The specific ratio can be set according to the actual situation.

[0093] like Figure 10 As shown, in some embodiments, the first drive mechanism 200 further includes a first worm gear 230 that is drivenly connected to the first screw 220, and the first power source 210 is provided with a first worm 211 that is drivenly connected to the first worm gear 230. Thus, when it is necessary to adjust the size of the first included angle, the first power source 210 outputs power, which drives the first worm gear 230 to rotate via the first worm 211, thereby driving the first screw 220 to rotate synchronously and coaxially, realizing the adjustment of the distance between the first adjusting member 311 and the second adjusting member 312, thereby completing the automatic adjustment of the first included angle.

[0094] like Figure 1 as well as Figure 10 As shown, in some embodiments, the transmission component 300 includes two parts, symmetrically arranged on the support component 100. The first screw 220 includes two parts, each corresponding to one of the transmission components 300. The two first screws 220 are respectively connected to the first worm gear 230. The threads of the two first screw bodies 221 have different directions, and the threads of the two second screw bodies 222 have different directions. Thus, by providing two transmission components 300 on the support component 100 and correspondingly arranging the first screws 220, and by providing massage components 20 on the driving members 322 of the transmission components 300, and by connecting the first worm gear 230 to the two first screws 220 respectively, and by ensuring that the threads of the two first screw bodies 221 and the two second screw bodies 222 have different directions, when the first driving component drives the first adjusting member 311 and the second adjusting member 312, the first adjusting member 311 and the second adjusting member 312 on both sides move towards or away from each other, thereby adjusting the position of the two massage components 20 to suit different users. The first drive mechanism 200 can drive the rotating shafts 321 of the two first screws 220 to rotate synchronously, which can reduce the power source and reduce the manufacturing cost of the massage device 1.

[0095] like Figure 2 As shown, in some embodiments, the massage component 20 is mounted on the drive component 322 via the mounting part 3221, and the second drive mechanism 30 is disposed on the support component 100 for driving the rotating shaft 321 to rotate.

[0096] like Figure 2 As shown, in some embodiments, the massage device 1 includes two massage components 20 and two transmission components 300, and a second drive mechanism 30 can drive the two transmission components 300 to rotate synchronously. Thus, a single second drive mechanism 30 can drive the two transmission components 300 to rotate synchronously, thereby driving the two massage components 20. This reduces the power source and lowers the manufacturing cost of the massage device 1.

[0097] It should be noted that the second drive mechanism 30 includes devices that directly provide rotational power, such as servo motors and rotary hydraulic cylinders, as well as other devices that indirectly provide rotational power, such as pneumatic rods / hydraulic cylinders / linear motors + gear rack mechanisms, pneumatic rods / hydraulic cylinders / linear motors + crank rocker mechanisms or crank slider mechanisms, servo motors + gearboxes, servo motors + flexible transmission mechanisms, etc., which can drive the rotating shaft 321 to rotate.

[0098] like Figure 2 as well as Figure 11As shown, in some embodiments, the second drive mechanism 30 includes a second power source 31 and a transmission unit 32. The second power source 31 is disposed on the support assembly 100, and the second power source 31 is connected to two transmission components 300 respectively through the transmission unit 32. In this way, the rotation of the rotating shaft 321 is realized by the cooperation of the second power source 31 and the transmission unit 32, so that the position between the second power source 31 and the rotating shaft 321 can be flexibly set, reducing the design difficulty of the massage device 1.

[0099] It should be noted that the transmission unit 32 can be implemented in various ways, including but not limited to belt drive assembly, chain drive assembly, gear drive assembly, etc.

[0100] It should be noted that the first power source 210 and the second power source 31 can be implemented in various ways, including motors, etc.

[0101] like Figure 11 As shown, in some embodiments, the transmission unit 32 includes a transmission gear 33 rotatably mounted on the support assembly 100, a second worm gear 34 coaxially rotatably connected to the transmission gear 33, and two gear sets 35 meshing with the transmission gear 33. The second power source 31 includes a second worm 36 that drives the second worm gear 34. The two gear sets 35 correspond one-to-one with the two transmission components 300 to drive the two rotating shafts 321 to rotate synchronously. Thus, when the massage device 1 is in use, the second power source 31 outputs power, which drives the second worm gear 34 to rotate via the second worm 36. This, in turn, drives the two gear sets 35 to rotate via the transmission gear 33, and drives the two rotating shafts 321 to rotate synchronously. Consequently, the two massage components 20 rotate synchronously to enable the massage device 1 to perform a massage.

[0102] like Figure 10 as well as Figure 11 As shown, in some embodiments, the transmission gear 33 includes a gear shaft, and the second worm gear 34 is provided with a second mounting groove. The gear shaft passes through the second mounting groove and is fixedly connected to the second worm gear 34. In this way, the gear shaft is fixedly connected to the second worm gear 34 through the second mounting groove, thereby realizing the transmission connection between the gear shaft and the second worm gear 34 to drive the gear shaft to rotate.

[0103] like Figure 2 As shown, in some embodiments, the supporting component 100 includes a first plate 120, which has a clearance notch 130. A gear shaft is rotatably mounted on the first plate 120 and meshes with a gear set 35 through the clearance notch 130. Thus, the gear shaft's rotatable mounting on the first plate 120 and meshing with the gear set 35 through the clearance notch 130 allows for a compact and miniaturized overall structure of the massage device 1, facilitating its portability.

[0104] In the aforementioned embodiment of the adjustment component 310, such as Figure 11 As shown, the gear set 35 is rotatably mounted on the first adjusting member 311, which is slidably connected to the bearing assembly 100. The sliding direction of the first adjusting member 311 is aligned with the axial direction of the gear shaft, and the length of the transmission teeth of the gear shaft is greater than the sliding distance of the first adjusting member 311. Thus, even if the first adjusting member 311 moves, the gear set 35 can still mesh with the transmission gear 33 to drive the rotating shaft 321 to rotate.

[0105] It should be noted that the "protrusion 3225" can be a part of the "eccentric cam 3224", that is, the "protrusion 3225" is integrally formed with other parts of the "eccentric cam 3224, such as the eccentric drive part 3222"; or it can be a separate component that can be separated from other parts of the "eccentric cam 3224, such as the eccentric drive part 3222", that is, the "protrusion 3225" can be manufactured independently and then combined with other parts of the "eccentric cam 3224, such as the eccentric drive part 3222" to form a whole. The expressions "a certain body" and "a certain part" in this disclosure are only one embodiment for ease of reading, and are not intended to limit the scope of protection of this disclosure. As long as it includes the above features and has the same function, it should be understood as an equivalent technical solution of this disclosure.

[0106] It should be noted that the "first screw 220" can be one of the parts of the "adjustment component 310" module, that is, it can be assembled into a module with the "other components of the adjustment component 310" and then modularly assembled; or it can be relatively independent from the "other components of the adjustment component 310" and can be installed separately, so that it can form a whole with the "other components of the adjustment component 310" in this device.

[0107] Similarly, the components included in the "components," "parts," and "mechanisms" of this disclosure can also be flexibly combined. They can be modularly produced according to actual needs and assembled as an independent module; or they can be assembled separately to form a module in this device. The division of the above-mentioned components in this disclosure is only one embodiment for ease of reading and is not intended to limit the scope of protection of this disclosure. Any technical solution that includes the above-mentioned components and has the same function should be understood as an equivalent technical solution of this disclosure.

[0108] When one component is considered to be "transmission connection" to another component, the two can be fixed in a detachable or non-detachable manner, as long as power transmission can be achieved. Methods such as socketing, snap-fitting, integral molding, and welding can be achieved in traditional technologies, and will not be elaborated here.

[0109] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0110] The above embodiments are merely illustrative of several implementation methods of this disclosure, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this disclosure, and these modifications and improvements all fall within the protection scope of this disclosure.
