Description

Technical Field

[0001] This application relates to the field of fascia gun technology, and more particularly to a fascia gun. Background Technology

[0002] In the field of modern health preservation and sports rehabilitation, fascia guns have been widely used as an effective muscle relaxation tool. The human muscular system is extremely complex and widely distributed, including facial muscles in the head, as well as numerous muscle groups in the neck, shoulders, back, chest, abdomen, and limbs. However, existing fascia guns have certain limitations in practical use. They are difficult to adjust the direction of the massage, which makes it impossible to ensure that the massage head can accurately act on the target muscle group when facing muscles in different locations and shapes. This limitation not only reduces the user experience but also restricts the applicability of fascia guns. Utility Model Content

[0003] In view of the above-mentioned shortcomings in related technologies, this application provides a fascia gun to improve the user experience and applicability of the fascia gun.

[0004] To address the aforementioned technical problems, in a first aspect, this application provides a fascia gun, which includes:

[0005] Gun head mounting base;

[0006] A gun head, wherein the gun head is disposed on the gun head mounting base;

[0007] The handle includes a fixed handle and a movable handle. The fixed handle is fixedly connected to the gun head mounting base, and the movable handle is rotatably connected to the end of the fixed handle away from the gun head mounting base.

[0008] The adjustment structure includes a first positioning part and a movable part. The first positioning part is disposed at the end of the fixed handle away from the gun head mounting seat. The movable part is movably disposed on the movable handle. The movable part is provided with a second positioning part. When the second positioning part is separated from the first positioning part, the movable handle can rotate relative to the fixed handle. When the second positioning part is inserted and engaged with the first positioning part, it can prevent the movable handle from rotating relative to the fixed handle.

[0009] Beneficial effects: It makes the grip more flexible and diverse. Users can choose different grip angles when the movable handle is fixed or rotated according to their own habits and operating scenarios to meet diverse needs. The rotation function of the movable handle allows the gun head to be flexibly adjusted to different angles, expanding the application scenarios of the fascia gun. The adjustment structure, through the cooperation of the first and second positioning parts, can lock the movable handle when precise operation is required to ensure operational stability, and can be unlocked when flexible movements are required to achieve quick switching and improve operational convenience. Moreover, the adjustment structure is located on the side, making reasonable use of space and avoiding the adjustment structure occupying the wiring space, thereby improving the user experience and the applicability of the fascia gun.

[0010] Optionally, the fixed handle and the gun head mounting base have a preset angle.

[0011] Beneficial effects: The preset angle allows the layout of the fixed handle and the gun head mounting base to better fit the normal grip and operation posture of the human body. When the user holds the fixed handle, the arm and wrist can be naturally extended without excessive twisting or force, reducing muscle fatigue and discomfort caused by prolonged unnatural posture, making operation easier and more comfortable, and improving the user experience.

[0012] When using a fascia gun to massage hard-to-reach areas such as the back, the movable handle can be rotated to a suitable angle to make the overall grip posture easier to fit the gun head against the back. For example, rotating the movable handle upwards at a certain angle to form a specific angle combination with the fixed handle allows the user to more easily extend their arm backwards, allowing the gun head to act on the back muscles at a suitable angle for a better massage effect. For leg and foot massage, the movable handle can be adjusted according to specific operating needs. For example, when massaging the legs, the movable handle can be rotated slightly outwards to provide more suitable space between the arm and leg, making it easier to control the movement of the gun head in different parts of the leg. When massaging the soles of the feet, the movable handle can be rotated to a position almost parallel to the fixed handle to extend the handle length, allowing the user to hold the fascia gun more steadily and apply the gun head vertically to the soles of the feet. This allows for various grip methods by rotating the movable handle, improving the applicability of the fascia gun.

[0013] Optionally, the active handle has a curved grip portion.

[0014] Beneficial effects: The curved grip conforms to the natural curve of the human hand, which can effectively distribute hand pressure, reduce fatigue caused by prolonged use, and make the user more comfortable to hold. The curved shape can also increase the contact area and friction between the hand and the movable handle, allowing users to better control the fascia gun regardless of the intensity, thus improving the safety of use.

[0015] Optionally, the fixed handle is integrally formed into the gun head mounting base.

[0016] Beneficial effects: The one-piece molded structure makes the overall structure of the fascia gun more stable, which can effectively reduce the shaking and deviation generated during high-frequency vibration. This ensures that the vibration frequency and force of the gun head are transmitted to the target muscle fascia tissue more stably and accurately, making the massage effect of the fascia gun better, relaxing the muscles more deeply, and relieving muscle soreness and fatigue.

[0017] During the high-speed vibration of the fascia gun, the one-piece molded structure avoids the risk of parts falling off due to the loose connection between the fixed handle and the gun head mounting base, reducing the possibility of accidental injury to the user and providing a more reliable safety guarantee, allowing the user to use it with peace of mind.

[0018] Optionally, one of the first positioning part and the second positioning part is a plug-in protrusion and the other is a plug-in groove;

[0019] The plurality of insertion protrusions are arranged at intervals along the rotation direction of the movable handle. The plurality of insertion slots are also arranged at intervals along the rotation direction of the movable handle. Each insertion protrusion can be inserted into a corresponding insertion slot to prevent the movable handle from rotating relative to the fixed handle; or...

[0020] There is one insertion protrusion and multiple insertion slots. The multiple insertion slots are arranged at intervals along the rotation direction of the movable handle. The insertion protrusion can be inserted and engaged with the corresponding insertion slot to prevent the movable handle from rotating relative to the fixed handle.

[0021] Beneficial effects: Multiple insertion protrusions or insertion slots are arranged at intervals along the rotation direction of the movable handle, so that when the movable handle is rotated to the preset angle, it can be positioned by the precise cooperation of the insertion protrusions and insertion slots, ensuring that the movable handle is stably fixed at a specific angle, thus improving the stability and reliability of the fascia gun during use.

[0022] Optionally, when there are multiple insertion protrusions, the insertion protrusions are evenly arranged along the rotation direction of the movable handle;

[0023] The plurality of the insertion slots are evenly arranged along the rotation direction of the movable handle.

[0024] Beneficial effects: When the movable handle is positioned at the preset angle, the evenly distributed plug protrusions and plug slots cooperate to distribute the external force on the gun head evenly to each plug point. Multiple evenly distributed plug points can effectively avoid excessive local stress, prevent structural damage caused by stress concentration, and ensure stable operation of the gun head.

[0025] Optionally, the groove wall of the insertion slot is a first guide cone surface, the outer wall of the insertion protrusion is a second guide cone surface, the outer diameter of the insertion protrusion gradually decreases along the direction close to the insertion slot, and the inner diameter of the insertion slot gradually increases along the direction close to the insertion protrusion.

[0026] Beneficial effects: The design of the first and second guide cone surfaces allows the insertion protrusion to automatically align when it approaches the insertion slot, reducing the difficulty of insertion. After the user adjusts the nozzle angle, the positioning components can cooperate more easily. The gradual design of the insertion protrusion's outer diameter decreasing and the insertion slot's inner diameter increasing plays a guiding role during insertion, allowing the moving parts to slide the insertion protrusion into the insertion slot more smoothly under the action of the reset parts, reducing jamming and collision, and improving the user experience.

[0027] Optionally, the end of the fixed handle away from the gun head mounting seat has a first side ear and a second side ear arranged opposite to each other along a first direction. Both the first side ear and the second side ear are provided with a rotating protrusion. The center of the rotating protrusion is located on the rotation axis of the movable handle, and the first direction is parallel to the rotation axis of the movable handle.

[0028] Along the first direction, the movable handle has a first end and a second end, and each of the first end and the second end is provided with a rotating groove that mates with the rotating protrusion. The center of the rotating groove is located on the rotation axis of the movable handle, so that the first end is rotatably connected to the first side ear, and the second end is rotatably connected to the second side ear.

[0029] Beneficial effects: The beneficial effects of this structural design are as follows: the rotating protrusions on the first and second side ears cooperate with the rotating grooves at both ends of the movable handle, and the centers of the rotating protrusions and rotating grooves are both located on the rotation axis of the movable handle, ensuring a stable rotational connection between the movable handle and the fixed handle, and making the rotation process of the movable handle smooth and stable.

[0030] Optionally, the first positioning part is disposed on the first side ear, and the movable member is movably disposed at the first end along the first direction;

[0031] The second end is provided with a wiring hole that extends through the second end along the first direction, and the wiring hole is located on the rotation axis of the movable handle.

[0032] Beneficial effects: The wiring hole is located on the rotation axis of the movable handle and passes through the second end, which facilitates the internal wiring of the fascia gun to pass through it, avoids the wiring from being squeezed or tangled when the movable handle is rotated, ensures that the wiring layout is neat, and improves the safety and stability of the product.

[0033] Optionally, both the first and second side ears are provided with a first positioning part;

[0034] The movable component includes two parts, which are respectively movably disposed at the first end and the second end along the first direction. When the two movable components are separated from their corresponding first positioning parts, the movable handle can rotate relative to the gun head mounting base.

[0035] Beneficial effects: Both the first and second side ears are equipped with a first positioning part, and the two ends of the movable handle are correspondingly equipped with movable parts. The double-sided positioning structure makes the connection of the movable handle more stable at the preset angle, reduces the shaking of the movable handle during use, improves the reliability of the fascia gun, and the movable handle can only rotate when the movable parts at both ends are far away from the first positioning part, reducing the risk of misoperation and improving the safety of use.

[0036] Optionally, the end of the fixed handle away from the gun head mounting seat is provided with a mounting hole;

[0037] At least a portion of the movable member extends out of the mounting hole, and when the movable member is pressed along the first direction to move it away from the first positioning part, the second positioning part separates from the first positioning part;

[0038] A reset member is provided between the movable member and the fixed handle. The reset member is used to provide a reset force to the movable member to move toward the first positioning part, so that the first positioning part and the second positioning part can be inserted and engaged along the first direction.

[0039] Beneficial effects: The movable part extends out of the mounting hole, making it convenient for users to press and operate directly to unlock and lock the movable handle. The operation is simple and intuitive. The reset part allows the movable part to automatically reset, achieving automatic positioning and locking of the movable handle and the gun head mounting seat, improving efficiency and ensuring that the angle of the movable handle remains stable during the use of the fascia gun.

[0040] Optionally, the reset element is a spring that extends along the first direction, with one end of the spring abutting against the movable handle and the other end abutting against the movable element.

[0041] Beneficial effects: Using a spring as the reset element, the elastic force generated by the spring extending in the first direction provides a stable and reliable reset force for the moving part, ensuring that the moving part can be reset quickly and accurately, and keeping the moving handle and the gun head mounting base firmly connected.

[0042] Optionally, the movable handle is provided with a receiving groove, the movable member is movably disposed in the receiving groove along the first direction, and an anti-rotation structure is provided between the movable member and the receiving groove to prevent the movable member from rotating relative to the movable handle.

[0043] Beneficial effects: Precise movement guidance: The receiving groove provides precise guidance for the movement of the moving part, ensuring that the moving part moves stably along the first direction, avoiding deviation of the moving part during movement, and ensuring the accuracy and stability of the angle adjustment operation of the moving handle.

[0044] Optionally, the anti-rotation structure includes a first anti-rotation plane disposed on the outer peripheral surface of the movable part and a second anti-rotation plane disposed on the groove wall of the receiving groove, wherein the first anti-rotation plane and the second anti-rotation plane engage in anti-rotation cooperation.

[0045] Beneficial effects: The tight fit between the two planes prevents rotation, which can precisely restrict the movement of the moving parts within the receiving groove to only move in the first direction, preventing rotation during use and ensuring the stability and reliability of the adjustment and positioning of the moving handle. In addition, the anti-rotation structure of the plane fit facilitates positioning and installation during the assembly of the fascia gun. If a malfunction occurs later, the repair and replacement of moving parts and other components are also relatively simple, reducing production and maintenance costs.

[0046] Optionally, a first positioning part is provided on both the first side ear and the second end;

[0047] The adjustment structure includes a first movable member, a second movable member, and a connecting member. The connecting member is connected between the first movable member and the second movable member along the first direction. The connecting member movably passes through the movable handle along the first direction and can move relative to the movable handle along the first direction. The first movable member and the second movable member are each provided with a second positioning part. When the first movable member approaches or moves away from the first positioning part on the first side ear, the connecting member can drive the second movable member to simultaneously approach or move away from the first positioning part on the second end.

[0048] Beneficial effects: A first positioning part is provided on both the first side ear and the second end of the movable handle. Combined with the adjustment structure consisting of the first and second movable parts and a connecting part, synchronous locking and unlocking on both sides is achieved, enhancing the stability of the connection between the movable handle and the fixed handle and reducing shaking of the movable handle during use. Only the first movable part needs to be operated to drive the second movable part to move synchronously via the connecting part, eliminating the need to operate both sides separately, simplifying the adjustment process and improving efficiency.

[0049] Optionally, a reset member is provided between the first movable member and the first end, the reset member being used to provide a reset force to the first movable member to move toward the first positioning part on the first side ear, and / or, a reset member is provided between the second side ear and the second movable member, the reset member being used to provide a reset force to the second movable member to move toward the first positioning part on the second end.

[0050] Beneficial effects: The reset component can provide a reset force for the first and / or second movable components. After the user completes the angle adjustment operation of the movable handle, the movable component can automatically return to the locked position, so that the first positioning part and the second positioning part can quickly complete the insertion and engagement, realize the automatic positioning and locking of the movable handle, ensure that the angle of the movable handle is stable and reliable during the use of the fascia gun, and avoid the effect of use due to the loosening of the movable handle.

[0051] Optionally, a first receiving groove is provided on the first end, a second receiving groove is provided on the second side ear, the first movable member is movably disposed in the first receiving groove along the first direction, and the second movable member is movably disposed in the second receiving groove along the first direction;

[0052] An anti-rotation structure is provided between the first movable member and the first receiving groove to prevent the first movable member from rotating relative to the movable handle, and / or,

[0053] An anti-rotation structure is provided between the second movable member and the second receiving groove to prevent the second movable member from rotating relative to the second side ear.

[0054] Beneficial effects: The first and second receiving slots provide space for the first and second movable parts to move along the first direction, respectively, and play a precise guiding role in the movement of the movable parts, ensuring that the movable parts can move stably and smoothly along the first direction. The anti-rotation structure prevents the first movable part from rotating relative to the movable handle and the second movable part from rotating relative to the second side ear, avoiding inaccurate positioning or unlocking abnormalities caused by the rotation of the movable parts, reducing the probability of misoperation, and improving the accuracy and reliability of the movable handle angle adjustment.

[0079] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0080] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0081] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0082] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0083] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0084] As described in the background section of this application, in the related technologies, fascia guns have certain limitations in actual use. They are difficult to adjust the direction of attack flexibly, which makes it impossible to ensure that the massage head can accurately act on the target muscle group when facing muscles of different locations and shapes. This limitation not only reduces the user experience, but also restricts the applicability of fascia guns.

[0085] In view of the above-mentioned problems, this application provides a fascia gun that makes the grip more flexible and diverse. Users can choose different grip angles when the movable handle is fixed or rotated according to their own habits and operating scenarios to meet diverse needs. The rotation function of the movable handle allows the gun head to be flexibly adjusted to different angles, which broadens the application scenarios of the fascia gun, thereby improving the user experience and the applicability of the fascia gun.

[0086] The technical solution of the fascia gun of this application will be further described below with reference to specific embodiments and accompanying drawings:

[0087] See Figures 1 to 6 This application provides a fascia gun 1, which includes: a gun head mounting base 100, a gun head 200, a handle 300, and an adjustment structure 400; the gun head 200 is disposed on the gun head mounting base 100; the handle 300 includes a fixed handle 300a and a movable handle 300b, the fixed handle 300a is fixedly connected to the gun head mounting base 100, and the movable handle 300b is rotatably connected to the end of the fixed handle 300a away from the gun head mounting base 100; the adjustment structure 400 includes a first positioning part 410 and a movable part 42. 0. The first positioning part 410 is disposed at the end of the fixed handle 300a away from the gun head mounting seat 100. The movable part 420 is movably disposed on the movable handle 300b. The movable part 420 is provided with a second positioning part 4201. When the second positioning part 4201 is separated from the first positioning part 410, the movable handle 300b can rotate relative to the fixed handle 300a. When the second positioning part 4201 is inserted and engaged with the first positioning part 410, it can prevent the movable handle 300b from rotating relative to the fixed handle 300a.

[0088] Thus, the movable handle 300b can rotate relative to the fixed handle 300a. When needed, the movable handle 300b can be rotated to a suitable grip angle to adapt to different users' grip habits and usage scenarios. For example, when massaging the deltoid muscle of the shoulder, the movable handle 300b can be adjusted to a tilt angle of about 30°, allowing the user to exert force more easily and accurately direct the gun head 200 to the target muscle. When massaging the hamstring muscle on the back of the thigh, the movable handle 300b can be adjusted to a straight position close to 180°, making it easier to use body weight to deeply relax the muscles and relieve post-exercise soreness. When not in use, the movable handle 300b can be rotated to a position that is flush with or close to flush with the fixed handle 300a, reducing the overall size of the fascia gun 1, making it easier to store and carry, thereby improving the user experience and the applicability of the fascia gun 1.

[0089] Furthermore, when the second positioning part 4201 is engaged with the first positioning part 410, it can prevent the movable handle 300b from rotating relative to the fixed handle 300a, thereby locking the movable handle 300b. This ensures that the handle 300 structure is stable when using the fascia gun 1 and will not rotate accidentally due to vibration or the user's gripping action, thus ensuring the stability of the user's grip and enabling the fascia gun 1 to act more accurately on the target area, improving the usage effect. It can also be unlocked when flexible movement is required, realizing quick switching and improving the ease of operation. Moreover, the adjustment structure 400 is located on the side, making reasonable use of space and avoiding the adjustment structure 400 occupying the wiring space.

[0090] In one possible embodiment, see Figure 1 and Figure 2 There is a preset angle between the fixed handle 300a and the gun head mounting base 100.

[0091] The preset included angle can be any angle, such as 60°, 90°, 100°, 120°, etc., and is not limited here.

[0092] The preset angle between the fixed handle 300a and the nozzle mounting base 100 allows the user's arm and wrist to be in a natural and relaxed posture when holding the fixed handle 300a. Compared with the straight design of the handle 300 and the nozzle mounting base 100, this angled structure avoids excessive bending or extension of the wrist during operation, reducing fatigue of the hand and wrist muscles.

[0093] Furthermore, when operating the fascia gun 1 with one hand, the preset angle helps to better control the direction and intensity of the gun head 200. Users can more easily and accurately aim the gun head 200 at the area requiring massage, improving operational stability and accuracy. For example, when massaging muscles on the side of the body, it is easier to adjust the angle of the gun head 200 for a more thorough massage. When massaging harder-to-reach areas such as the back with the fascia gun 1, the movable handle 300b can be rotated to a suitable angle, making the overall grip posture easier to bring the gun head 200 close to the back. For instance, rotating the movable handle 300b upwards at a certain angle to form a specific angle combination with the fixed handle 300a allows the user to more easily extend their arm backwards. To achieve a better massage effect, the gun head 200 is positioned at a suitable angle to apply pressure to the back muscles. For leg and foot massage, the movable handle 300b can be adjusted according to specific operational needs. For example, when massaging the legs, the movable handle 300b can be rotated slightly outward to provide more suitable space between the arm and leg when holding the gun, making it easier to control the movement of the gun head 200 to different parts of the leg. When massaging the soles of the feet, the movable handle 300b can be rotated to a position almost parallel to the fixed handle 300a to extend the length of the handle 300, allowing the user to hold the fascia gun 1 more steadily and apply the gun head 200 vertically to the soles of the feet. This allows for various gripping methods by rotating the movable handle 300b, improving the applicability of the fascia gun 1.

[0094] In one possible embodiment, see Figure 7 The movable handle 300b has a curved grip portion 300b1.

[0095] The movable handle 300b has a curved grip 300b1, which can better fit the natural curve of the human hand to effectively distribute hand pressure, reduce fatigue caused by prolonged use, and make the user's grip more comfortable. The curved shape can increase the contact area and friction between the hand and the movable handle 300b, allowing the user to better control the fascia gun 1 regardless of the intensity, thus improving the safety of use.

[0096] In one possible embodiment, the fixed handle 300a is integrally formed into the gun head mounting base 100.

[0097] In this way, the fixed handle 300a and the gun head mounting base 100 become a whole, eliminating the connection gap between the two and effectively avoiding structural instability caused by loose connection points. For example, when the fascia gun 1 is continuously turned on at a higher level for massage, the one-piece molded structure can evenly distribute the stress caused by vibration and will not form stress peaks at the connection points, reducing the probability of failure.

[0098] Furthermore, it ensures that the relative position between the gun head mounting base 100 and the fixed handle 300a is accurate and fixed, and that the working angle and direction of the gun head 200 will not be affected by minor changes in the connection parts during use. This ensures the stability and accuracy of the operation of the fascia gun 1, allowing the user to more accurately aim the gun head 200 at the area to be massaged and improve the massage effect.

[0099] In one possible embodiment, one of the first positioning part 410 and the second positioning part 4201 is a plug-in protrusion and the other is a plug-in groove; there are multiple plug-in protrusions, which are arranged at intervals along the rotation direction of the movable handle 300b, and there are multiple plug-in grooves, which are arranged at intervals along the rotation direction of the movable handle 300b. The multiple plug-in protrusions can be plugged into the corresponding plug-in grooves to prevent the movable handle 300b from rotating relative to the fixed handle 300a; or, there is one plug-in protrusion and multiple plug-in grooves, which are arranged at intervals along the rotation direction of the movable handle 300b. The plug-in protrusion can be plugged into the corresponding plug-in groove to prevent the movable handle 300b from rotating relative to the fixed handle 300a.

[0100] See Figure 5 , Figure 6 and Figure 8 Multiple protrusions and slots are arranged at intervals along the rotation direction of the movable handle 300b, providing multiple precise positioning points. When the movable handle 300b rotates to different positions, the corresponding protrusions and slots cooperate to accurately position the movable handle 300b at a preset angle, meeting the diverse needs of different users for grip angle. In addition, the multiple insertion points make the connection between the movable handle 300b and the fixed handle 300a more stable. During use, it can better withstand the external forces generated by gripping and operation, reduce the possibility of accidental rotation of the movable handle 300b, and improve the stability and reliability of use.

[0101] Furthermore, with multiple plug positions available, the 300b handle can be stopped at different angles at any time during rotation, allowing for stepless adjustment and making the rotation operation more flexible and convenient.

[0102] When a single plug protrusion engages with multiple plug slots, the structural complexity of the movable handle 300b and the fixed handle 300a is reduced, making the overall structure of the product simpler. Although there is only one plug protrusion, the multiple plug slots are arranged at intervals along the rotation direction, which can still enable the movable handle 300b to be positioned at different angles, meeting the user's basic needs for different grip angles.

[0103] Furthermore, when rotating the movable handle 300b, the user only needs to align the plug protrusion with the corresponding plug slot to complete the positioning, making the operation relatively simple and quick.

[0104] In one possible embodiment, when there are multiple insertion protrusions, the insertion protrusions are evenly arranged along the rotation direction of the movable handle 300b; the multiple insertion slots are evenly arranged along the rotation direction of the movable handle 300b.

[0105] Multiple evenly arranged protrusions and slots cooperate to ensure that when the movable handle 300b and the fixed handle 300a are locked, the force can be evenly distributed on each insertion point. Compared with single-point or non-uniformly distributed insertion structures, this design can avoid stress concentration. The force borne by each insertion point is relatively small and balanced. For example, when the fascia gun 1 vibrates or is disturbed by external forces during operation, the evenly distributed insertion points can share these forces, thereby reducing the possibility of deformation, damage or loosening of a single insertion point due to excessive force.

[0106] Furthermore, the evenly distributed protrusions and slots provide precise positioning for the movable handle 300b. Because the spacing between each engagement point is equal, the movable handle 300b can only engage at specific angular positions during rotation. This limits the range of rotation of the movable handle 300b, preventing it from rotating arbitrarily. Even under prolonged use or significant external impact, the movable handle 300b can maintain its set angular position without any angular deviation.

[0107] In one possible embodiment, see Figure 10 The groove wall of the insertion slot is the first guide cone surface, the outer wall of the insertion protrusion is the second guide cone surface, the outer diameter of the insertion protrusion gradually decreases along the direction close to the insertion slot, and the inner diameter of the insertion slot gradually increases along the direction close to the insertion protrusion.

[0108] When the movable part 420 moves toward the first positioning part 410, the insertion protrusion with the second guide cone surface begins to approach the insertion groove with the first guide cone surface. As the distance between the two gradually decreases, under the guidance of the first guide cone surface and the second guide cone surface, it will automatically move toward the center position of the insertion groove. Even if there is a certain deviation in the rotation angle of the gun head mounting seat 100, the first guide cone surface and the second guide cone surface can guide the insertion protrusion to smoothly enter the insertion groove until the two are completely matched and locked, restricting the rotation of the movable handle 300b relative to the handle 300.

[0109] In this way, the first guide cone and the second guide cone cooperate to form a smooth guide path, allowing the insertion protrusion to slide quickly into the insertion slot. Compared with the ordinary straight insertion structure, the insertion time is shortened, allowing users to quickly lock the movable handle 300b at the required angle and start using the fascia gun 1 in time, thus improving the user experience.

[0110] Furthermore, after the insertion protrusion penetrates into the insertion groove, the first guide cone surface and the second guide cone surface gradually fit together tightly. When the fascia gun 1 is working, the force generated by the high-frequency vibration will be evenly distributed across the entire contact surface, preventing loosening or damage caused by local stress concentration and enhancing the stability of the connection between the movable handle 300b and the fixed handle 300a.

[0111] In one possible embodiment, see Figure 4 , Figure 7 , Figure 9 as well as Figure 10 The fixed handle 300a has a first side ear 300a1 and a second side ear 300a2 arranged opposite each other along a first direction at the end away from the gun head mounting seat 100. The first side ear 300a1 and the second side ear 300a2 are each provided with a rotating protrusion 300a3. The center of the rotating protrusion 300a3 is located on the rotation axis of the movable handle 300b, and the first direction is parallel to the rotation axis of the movable handle 300b. Along the first direction, the movable handle 300b has a first end 310 and a second end 320. The first end 310 and the second end 320 are each provided with a rotating groove 330 that cooperates with the rotating protrusion 300a3. The center of the rotating groove 330 is located on the rotation axis of the movable handle 300b, so that the first end 310 is rotatably connected to the first side ear 300a1, and the second end 320 is rotatably connected to the second side ear 300a2.

[0112] In this embodiment, the first direction is... Figure 9 The direction indicated by the middle arrow X1.

[0113] The movable handle 300b is rotatably connected to the rotating protrusion 300a3 on the first side ear 300a1 and the second side ear 300a2 through the rotating groove 330. During installation, simply align the rotating groove 330 at the end of the movable handle 300b with the rotating protrusion 300a3 and insert it directly to complete the installation. This saves assembly time, reduces assembly difficulty, and improves production efficiency. Furthermore, the centers of the rotating protrusion 300a3 and the rotating groove 330 are both located on the rotation axis of the movable handle 300b, ensuring that the rotation axis of the movable handle 300b is accurate after installation. This avoids abnormal rotation caused by installation deviation and lays the foundation for smooth rotation and precise adjustment of the movable handle 300b in the future.

[0114] In addition, the first side ear 300a1 and the second side ear 300a2 support the movable handle 300b from opposite sides. During the operation of the fascia gun 1, even if the movable handle 300b is subjected to a large external force or high-frequency vibration, this structure can effectively resist shaking and displacement, ensuring that the movable handle 300b rotates stably and improving the user's operating experience.

[0115] In one possible embodiment, see Figure 10The first positioning part 410 is disposed on the first side ear 300a1, and the movable part 420 is movably disposed on the first end 310 along the first direction; the second end 320 is provided with a wiring hole 3201 that passes through the second end 320 along the first direction, and the wiring hole 3201 is located on the rotation axis of the movable handle 300b.

[0116] The wiring hole 3201 is located on the rotation axis of the movable handle 300b, providing a stable and convenient channel for the internal wiring. When connecting and arranging wiring, there is no need for complicated wiring bends and planning, allowing the wiring to be smoothly transmitted from the movable handle 300b to the gun head 200 (for example, the gun head mounting base usually contains a battery, and the movable handle 300b usually contains a control board). This simplifies the wiring process and reduces the difficulty of wiring. In this way, all the wiring is arranged in an orderly manner through the wiring hole 3201, avoiding messy tangling of wiring inside the gun body. This makes the internal layout of the product neater and prevents exposed wiring from affecting the appearance of the product.

[0117] Furthermore, during the rotation of the movable handle 300b, since the wiring hole 3201 is located on the rotation axis, the wiring will not be subjected to additional torsion, pulling and friction during rotation, which reduces the risk of damage and breakage of the wiring due to mechanical stress.

[0118] Of course, the location of the wiring hole 3201 is not limited to the above-mentioned locations, for example, as Figure 7 As shown, it can also be set at the end of the movable handle 300b.

[0119] In one possible embodiment, see Figure 11 and Figure 12 The first side ear 300a1 and the second side ear 300a2 are each provided with a first positioning part 410; the movable part 420 includes two parts, and the two movable parts 420 are respectively movably disposed at the first end 310 and the second end 320 along the first direction. When the two movable parts 420 are separated from the corresponding first positioning part 410, the movable handle 300b can rotate relative to the gun head mounting seat 100.

[0120] Both the first side ear 300a1 and the second side ear 300a2 have a first positioning part 410, corresponding to two movable parts 420. This double-sided positioning structure provides more stable support and positioning for the movable handle 300b. During use, regardless of the direction of force applied to the movable handle 300b, the double-sided positioning structure can better balance the force, preventing the movable handle 300b from shaking or shifting, ensuring stability and reliability during use. Furthermore, the two movable parts 420 cooperate with the first positioning parts 410 on both sides, forming multiple connection points and support points between the movable handle 300b and the gun head mounting base 100. This multi-connection-point structural design effectively disperses the stress generated during use, improving the overall structural strength and durability. For example, the vibration generated when the fascia gun 1 is working and the force applied by the user when holding it can be evenly transmitted and dispersed through these connection points, reducing the stress burden on individual components and extending the product's service life.

[0121] Furthermore, when the user needs to adjust the movable handle 300b, the user needs to press the two movable parts 420 simultaneously from both sides so that the second positioning part 4201 on the two movable parts 420 is moved away from the corresponding first positioning part 410, so that the movable handle 300b can rotate, thereby preventing the movable part 420 from rotating due to errors during use.

[0122] In one possible embodiment, see Figure 12 The fixed handle 300a has a mounting hole at its end away from the gun head mounting base 100; at least a portion of the movable member 420 extends out of the mounting hole; when the movable member 420 is pressed along the first direction to move it away from the first positioning part 410, the second positioning part 4201 separates from the first positioning part 410; a reset member 500 is provided between the movable member 420 and the fixed handle 300a, the reset member 500 is used to provide a reset force to the movable member 420 to move toward the first positioning part 410, so that the first positioning part 410 and the second positioning part 4201 are inserted and engaged along the first direction.

[0123] The reset element 500 can be any form of reset element 500, such as a spring or rubber block, and is not limited here. In this embodiment, the first direction is... Figure 12 The direction indicated by the middle arrow X2.

[0124] When the user needs to adjust the angle of the movable handle 300b, they press the movable part 420 protruding from the mounting hole with their finger. At this time, the movable part 420 overcomes the restoring force of the reset part 500 and moves away from the first positioning part 410 along the first direction. As the movable part 420 moves, the second positioning part 4201 on the movable part 420 gradually separates from the first positioning part 410 on the fixed handle 300a, thereby releasing the restriction on the rotation of the movable handle 300b. The movable handle 300b can rotate relative to the fixed handle 300a. The user can rotate the movable handle 300b to a suitable angle according to their own needs to adapt to different massage scenarios and grip habits. When the movable handle 300b is rotated to the target angle, the user releases their finger pressing the movable part 420. At this time, the reset part 500 plays a role, providing a restoring force to the movable part 420 to move towards the first positioning part 410. Under the action of the reset force, the movable part 420 moves along the first direction, so that the first positioning part 410 and the second positioning part 4201 are re-engaged, thereby preventing the movable handle 300b from rotating relative to the fixed handle 300a, and completing the locking after angle adjustment.

[0125] The design of the movable part 420 extending out of the mounting hole allows the user to easily touch the movable part 420 for convenient pressing operation. The pressing to unlock and releasing to lock operation is simple and easy to understand. In addition, the reset force provided by the reset part 500 ensures that the first positioning part 410 and the second positioning part 4201 can be tightly inserted and cooperate, which enhances the stability of the movable handle 300b after locking. During the operation of the fascia gun 1, high-frequency vibration will not cause the movable handle 300b to be accidentally unlocked and rotated, ensuring safety and stability during use.

[0126] In one possible embodiment, see Figure 12 The reset component 500 is a spring that extends in the first direction. One end of the spring abuts against the movable handle 300b, and the other end abuts against the movable component 420.

[0127] The spring has good elastic deformation capability. When the user presses the movable part 420 to unlock the movable handle 300b, the spring can be quickly compressed. At the moment the user releases the movable part 420, the spring immediately releases its elastic potential energy, pushing the movable part 420 to quickly reset, so that the first positioning part 410 and the second positioning part 4201 can quickly engage and cooperate, realizing the quick locking of the gun head mounting seat 100 and improving operating efficiency.

[0128] Furthermore, the spring has a simple structure and small size. Its installation method, in which one end abuts against the movable handle 300b and the other end abuts against the movable part 420, does not require complex installation space and structural design, and can flexibly adapt to various fixed handles 300a and handle 300 structures.

[0129] In addition, when the fascia gun 1 is working, the high-frequency vibration generated by the gun head 200 will be transmitted to the adjustment structure 400 through the fixed handle 300a. As an elastic element, the spring can absorb and buffer these vibrations to a certain extent, reduce the impact of vibration on the moving part 420 and the positioning part, avoid loosening or wear of parts due to vibration, and further improve the stability and durability of the adjustment structure 400.

[0130] In one possible embodiment, see Figure 6 The movable handle 300b is provided with a receiving groove 340, and the movable member 420 is movably disposed in the receiving groove 340 along the first direction. An anti-rotation structure 600 is provided between the movable member 420 and the receiving groove 340 to prevent the movable member 420 from rotating relative to the movable handle 300b.

[0131] When adjusting the angle of the movable handle 300b, the anti-rotation structure 600 ensures that the movable part 420 can only move in a straight line in the receiving groove 340 along the pressing direction, avoiding the normal insertion and separation of the movable part 420 with the first positioning part 410 due to the rotation of the movable part 420, and ensuring the accurate realization of the angle adjustment and positioning functions of the movable handle 300b.

[0132] During the operation of the fascia gun 1, the high-frequency vibration of the gun head 200 may cause the moving part 420 to rotate. The anti-rotation structure 600 can effectively suppress the rotation of the moving part 420 caused by the vibration, prevent it from causing displacement or shaking of the moving handle 300b, provide users with a stable grip and operation experience, and avoid poor massage effect or accidental injury caused by shaking.

[0133] In one possible embodiment, see Figures 6 to 8 The anti-rotation structure 600 includes a first anti-rotation plane 610 disposed on the outer peripheral surface of the movable member 420 and a second anti-rotation plane 620 disposed on the groove wall of the receiving groove 340, wherein the first anti-rotation plane 610 and the second anti-rotation plane 620 are anti-rotation engaged.

[0134] When the movable part 420 is placed in the receiving groove 340, the first anti-rotation plane 610 and the second anti-rotation plane 620 are in close contact. Due to the tight contact between the planes, the movable part 420 will be immediately blocked by the second anti-rotation plane 620 when it rotates. The friction between the first anti-rotation plane 610 and the second anti-rotation plane 620 will generate a resistance torque opposite to the rotation direction of the movable part 420, thereby restricting the movable part 420 from rotating around its axis. Thus, during the adjustment of the angle of the movable handle 300b, the second positioning part 4201 on the movable part 420 can always be aligned with the fixed handle 300b. The first positioning part 410 on a maintains the correct relative position. When the two are connected, the movable part 420 will not rotate due to misoperation or external force, ensuring precise insertion between the positioning parts and achieving precise locking of the angle of the movable handle 300b. When the fascia gun 1 is working, the tight fit of the first anti-rotation plane 610 and the second anti-rotation plane 620 continuously plays a limiting role during the vibration of the gun head 200, resisting the torque generated by the vibration. The friction generated between the two can effectively consume the energy transmitted to the movable part 420 by the vibration, and prevent the gun head mounting seat 100 from shaking due to the rotation of the movable part 420.

[0135] In addition, the planar structure machined on the outer peripheral surface of the movable part 420 and the groove wall of the receiving groove 340 simplifies the manufacturing process of the movable part 420 compared to the complex anti-rotation design such as teeth and slots. Moreover, the design of the two planes fitting together makes it easier to determine the direction of the movable part 420 when it is installed into the receiving groove 340, reducing the assembly difficulty and the product defect rate caused by assembly errors.

[0136] Of course, the anti-rotation structure 600 is not limited to the above structure. For example, the anti-rotation structure 600 can also be a keyway anti-rotation structure 600: a protruding key is provided on the outer peripheral surface of the movable part 420, and a matching keyway is machined on the groove wall of the receiving groove 340. During installation, the key is aligned with the keyway and inserted, so that the movable part 420 can only move along the direction of the keyway and cannot rotate around its own axis; or, a pin anti-rotation structure 600: pin holes are opened at corresponding positions on the movable part 420 and the receiving groove 340. During installation, the pin is passed through the two pin holes. In this way, the movable part 420 is restricted by the pin and cannot rotate relative to the receiving groove 340, and so on.

[0137] In one possible embodiment, see Figures 13 to 15Both the first side ear 300a1 and the second end 320 are provided with a first positioning part 410; the adjustment structure 400 includes a first movable member 430, a second movable member 440 and a connecting member 450. The connecting member 450 is connected between the first movable member 430 and the second movable member 440 along a first direction. The connecting member 450 is movably inserted through the movable handle 300b along the first direction and can move relative to the movable handle 300b along the first direction. Both the first movable member 430 and the second movable member 440 are provided with a second positioning part 4201. When the first movable member 430 approaches or moves away from the first positioning part 410 on the first side ear 300a1, the connecting member 450 can drive the second movable member 440 to simultaneously approach or move away from the first positioning part 410 on the second end 320.

[0138] In this embodiment, the first direction is Figure 14 The direction indicated by the middle arrow X3.

[0139] The first movable part 430 and the second movable part 440 are connected by the connector 450. The user only needs to operate one of the movable parts 420 to drive the other movable part 420 to move closer to or further away from the corresponding first positioning part 410. For example, when adjusting the angle of the handle 300, the user does not need to operate the two movable parts 420 separately, which improves the convenience of use. During the massage, different grip angles can be quickly switched to meet the needs of massaging different parts of the body.

[0140] Furthermore, both the first side ear 300a1 and the second end 320 are provided with a first positioning part 410, and the second positioning part 4201 on the first movable member 430 and the second movable member 440 cooperate with it to form a double-sided cooperative positioning structure. When using the fascia gun 1, the double-sided positioning points can evenly distribute the force on the handle 300, effectively avoiding the shaking or displacement of the handle 300 caused by uneven force on one side. When the gun head 200 is subjected to a large reaction force during the massage, the double-sided positioning structure can ensure that the handle 300 always remains stable, improving the safety and stability of use.

[0141] In one possible embodiment, see Figure 14 A reset member 500 is provided between the first movable member 430 and the first end 310. The reset member 500 is used to provide a reset force to the first movable member 430 to move toward the first positioning part 410 on the first side ear 300a1, and / or, a reset member 500 is provided between the second side ear 300a2 and the second movable member 440. The reset member 500 is used to provide a reset force to the second movable member 440 to move toward the first positioning part 410 on the second end 320.

[0142] When a reset member 500 is provided only between the first movable member 430 and the first end 310, the user pushes the first movable member 430 in the first direction to overcome the reset force of the reset member 500 and move it away from the first positioning part 410 on the first side ear 300a1. Under the action of the connector 450, the second movable member 440 moves away from the first positioning part 410 on the second end 320. At this time, the movable handle 300b is unlocked and can be adjusted in angle. The user rotates the movable handle 300b to a suitable angle as needed and then releases the first movable member 430. The reset member 500 releases its reset force and pushes the first movable member 430 toward the first positioning part 410 on the first side ear 300a1. Under the action of the connector 450, the second movable member 440 moves closer to the first positioning part 410 on the second end 320, thereby locking the movable handle 300b.

[0143] When the reset member 500 is provided only between the second side ear 300a2 and the second movable member 440, the user pushes the first movable member 430 along the first direction. The connector 450 drives the second movable member 440 to move away from the first positioning part 410 on the second side ear 300a2, so that it overcomes the reset force of the reset member 500. The movable handle 300b is unlocked. After adjusting to the required angle, the user releases the first movable member 430. The reset member 500 provides a reset force, pushing the second movable member 440 closer to the first positioning part 410 on the second end 320. Under the action of the connector 450, the first movable member 430 moves closer to the first positioning part 410 on the first side ear 300a1, thus locking the movable handle 300b.

[0144] When a reset element 500 is provided between the first movable member 430 and the first end 310, and a reset element 500 is provided between the second side ear 300a2 and the second movable member 440, after the user releases the movable member 420, the two reset elements 500 simultaneously provide a reset force, pushing the first and second movable members 440 to quickly and accurately approach the corresponding first positioning part 410, thereby locking the movable handle 300b.

[0145] In one possible embodiment, see Figure 6 and Figure 14 A first receiving groove 340a is provided on the first end 310, and a second receiving groove 340b is provided on the second side ear 300a2. A first movable member 430 is movably disposed in the first receiving groove 340a along a first direction, and a second movable member 440 is movably disposed in the second receiving groove 340b along the first direction. An anti-rotation structure 600 is provided between the first movable member 430 and the first receiving groove 340a to prevent the first movable member 430 from rotating relative to the movable handle 300b, and / or, an anti-rotation structure 600 is provided between the second movable member 440 and the second receiving groove 340b to prevent the second movable member 440 from rotating relative to the second side ear 300a2.

[0146] The anti-rotation structure 600 prevents the first movable member 430 and the second movable member 440 from rotating relative to the movable handle 300b or the second side ear 300a2, so that they can maintain accurate position and orientation when positioning along the first direction. This ensures that the second positioning part 4201 on the first movable member 430 and the second movable member 440 precisely cooperates with the first positioning part 410 on the first side ear 300a1 and the second end 320, improving the positioning accuracy of the adjustment structure 400 and ensuring that the movable handle 300b can be accurately locked after being adjusted to a specific angle, avoiding positioning deviation caused by the rotation of the movable member 420.

[0147] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
