Description

Technical Field

[0001] This utility model relates to the field of fascia gun technology, and in particular to a fascia gun with a multi-morphological structure. Background Technology

[0002] Fascia guns, also known as deep myofascial impactors, use a specially designed high-speed motor inside to drive the tapping head and generate high-frequency vibrations that penetrate deep into the muscles. This high-frequency vibration can achieve a massage effect, reducing local tissue tension, relieving muscle soreness, and promoting blood circulation.

[0003] Existing fascia guns generally include single-head and double-head fascia guns. Their overall structure is mostly in the shape of a "7", "T", or "F". For example, a fascia gun published in Chinese utility model patent CN223054735U on July 4, 2025, has a constant structural length and a short handle. When massaging body parts such as the arms and legs, this fascia gun can easily reach these parts. However, when massaging areas that are difficult to reach by hand, such as the back, the limited arm length and bending angle will prevent the ideal massage effect from being achieved due to the insufficient length of the handle.

[0004] Another example is a new type of fascia gun published on October 14, 2022, with the publication number CN217566740U. The fascia gun body is roughly rod-shaped and of a constant length, and is not adjustable. It has a main installation section, an installation head, and a handle extension section. Although the fascia gun body is longer, which makes it easier to massage the back, the overall length of this type of fascia gun makes it cumbersome and inconvenient to operate when using it to massage the arms, legs, and other parts of the body.

[0005] The existing fascia guns, with their non-adjustable overall length, limit their application scenarios and cannot meet users' needs in different situations. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a fascia gun with a multi-form structure to solve the problem that the design of the existing fascia gun with an overall non-adjustable length limits the application scenarios of the fascia gun and cannot meet the needs of users to choose the use according to their own needs in different scenarios.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fascia gun with a multi-form structure, including a handle and a massage part, and further comprising: Bending extension; The fascia gun has a first usage state when the handle and massage parts are fixed by the detachable fixing mechanism, and a second usage state when the handle and massage parts are fixed by the detachable fixing mechanism at both ends of the bending extension.

[0008] Preferably, the detachable fixing mechanism includes a first disassembly and a second disassembly and a second disassembly and a third disassembly and a fourth disassembly and a fifth disassembly and a sixth ...

[0009] Preferably, the first and second disassembly structures are rotated relative to each other after docking to lock them in place.

[0010] Preferably, the first and second disassembly structures are fixed by snap-fit ​​after docking.

[0011] Preferably, the bending extension includes at least one extension structure, and each extension structure is provided with a first disassembly structure and a second disassembly structure at both ends. When there are two or more extension structures, two adjacent extension structures are detachably and fixedly connected through the first disassembly structure and the second disassembly structure.

[0012] Preferably, the material of the extension structure is a deformable material, and the extension structure includes a deformable support member, the two ends of which are respectively detachably fixed to a first disassembly structure and a second disassembly structure.

[0013] Preferably, the extension structure further includes a protective sleeve, which is fitted around the deformable support member.

[0014] Preferably, it also includes a limiting structure to prevent the protective sleeve from sliding on the deformable support.

[0015] Preferably, the limiting structure includes a recess and a protrusion adapted to the recess, the first disassembly structure includes a first connecting part, the second disassembly structure includes a second connecting part, when the first connecting part and / or the second connecting part has at least one recess or protrusion on its periphery, the inner wall of the protective sleeve has at least one protrusion or recess, and when the protective sleeve is fitted around the deformable support, the protrusion is located inside the recess.

[0016] Preferably, the limiting structure includes a stepped surface and an inner edge. The first and second disassembly structures are each provided with at least one stepped surface. The protective sleeve is open at both ends and has several inner edges extending toward the center of the opening. When the protective sleeve is fitted around the deformable support, each inner edge abuts against a stepped surface.

[0017] Compared with the prior art, the beneficial effects that this utility model can achieve are: When using a fascia gun to massage the arms, legs, or other areas, the handle and massage unit are fixed together using a detachable fixing mechanism to assemble the fascia gun into its first usage state. When using the fascia gun to massage the back, the handle, bending extension, and massage unit are fixed together using the same detachable fixing mechanism to assemble the fascia gun into its second usage state. This extends the overall length of the fascia gun, allowing users to freely assemble and adjust its length and usage configuration. This makes it convenient for users to choose the appropriate use method for different scenarios, thus broadening its applicability. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a fascia gun with a multi-form structure, including a handle part 1 and a massage part 2. The massage part 2 is provided with a transmission mechanism, which specifically includes a motor and a cam reciprocating motion structure. This is the existing structure of fascia gun movement. The specific working principle will not be described in detail here. The fascia gun can be a single-head fascia gun or a double-head fascia gun. The figure shows a double-head fascia gun as an example. The fascia gun also includes a bending extension part and a detachable fixing mechanism. When people need to use a fascia gun to massage their arms, legs, or other areas, the handle 1 and the massage unit 2 are fixed together via a detachable fixing mechanism, thus assembling the fascia gun. Figure 1 The first usage state shown is sufficient. When people need to use the fascia gun to massage their back, the handle 1, the bending extension, and the massage part 2 are fixedly assembled using the detachable fixing mechanism, thus assembling the fascia gun. Figure 2 The second usage state shown extends the overall length of the fascia gun, allowing users to freely assemble and adjust its overall length and usage form. This makes it convenient for users to choose to use it according to their own needs in different scenarios, thus broadening its applicability.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the detachable fixing mechanism includes a first disassembly and assembly structure 4 and a second disassembly and assembly structure 5 that are detachably and fixedly connected. The two ends of the bending extension are respectively provided with the first disassembly and assembly structure 4 and the second disassembly and assembly structure 5. When the handle part 1 is provided with the first disassembly and assembly structure 4 or the second disassembly and assembly structure 5, the massage part 2 is provided with the second disassembly and assembly structure 5 or the first disassembly and assembly structure 4. The detachable fixing mechanism composed of the first disassembly and assembly structure 4 and the second disassembly and assembly structure 5 can realize the fascia gun in the first use state with a relatively short length by fixing the handle part 1 and the massage part 2, or the fascia gun in the second use state with a relatively long length by fixing the handle part 1, the bending extension and the massage part 2.

[0022] like Figures 4-12 As shown, the first disassembly structure 4 and the second disassembly structure 5 are connected and rotated relative to each other to lock them in place. The specific structures of the first disassembly / assembly structure 4 and the second disassembly / assembly structure 5 can be divided into the following three cases: The first scenario: (e.g.) Figures 4-8 As shown, the second disassembly structure 5 includes a second cylinder 51, and the first disassembly structure 4 includes a first cylinder 41. One end of the first cylinder 41 has an opening that matches the size of the second cylinder 51. At least one positioning block 42 is fixed to the inner wall of the opening. The side of the positioning block 42 that is opposite to the inner wall of the opening has a positioning groove 43 along the central axis of the first cylinder 41. The outer edge of the second cylinder 51 has a second sliding groove 53 and a first sliding groove 52 that is not smaller than the size of the positioning block 42 along its central axis. The second sliding groove 53 is connected to the first sliding groove 52 in an L-shape. The inner wall of the second sliding groove 53 is provided with a limiting member 54. After the second cylinder 51 enters the first cylinder 41, it rotates relative to the first cylinder 41. When the positioning block 42 moves from the first sliding groove 52 to the second sliding groove 53, the limiting member 54 moves into the positioning groove 43, and the positioning block 42 is in contact with the inner wall of the second sliding groove 53. The limiting component 54 is a spring-loaded positioning ball or / and a rubber strip; This example illustrates the use of two positioning blocks 42 and two limiting components 54, one of which is a spring-loaded positioning ball and the other is a rubber strip: When it is necessary to fix the first disassembly structure 4 and the second disassembly structure 5, align one end of the second cylinder 51 with the opening of the first cylinder 41, and insert the positioning block 42 into the first slide groove 52 until the positioning block 42 is directly opposite the second slide groove 53. Then rotate the first cylinder 41 or the second cylinder 51 in the forward direction so that the positioning block 42 can enter the second slide groove 53. When the limiting member 54 is a spring positioning ball, when the first cylinder 41 or the second cylinder 51 is rotated in the forward direction, the positioning block 42 presses the spring positioning ball until the spring positioning ball is finally located in the positioning groove 43. Thus, the first cylinder 41 and the second cylinder 51 will not easily rotate relative to each other. And because the limiting member 54 moves into the positioning groove 43, the positioning block 42 is in contact with the inner wall of the second slide groove 53. At this time, the first cylinder 41 and the second cylinder 51 will not easily move relative to each other along their central axis, thus completing the fixation of the first cylinder 41 and the second cylinder 51 (the first disassembly structure 4 and the second disassembly structure 5). When the limiting member 54 is a rubber strip, when the first cylinder 41 or the second cylinder 51 is rotated in the forward direction, due to the interference fit of the rubber strip, when the rubber strip moves into the positioning groove 43, the first cylinder 41 and the second cylinder 51 will not easily rotate relative to each other. Also, because the limiting member 54 moves into the positioning groove 43, the positioning block 42 is in contact with the inner wall of the second slide groove 53. At this time, the first cylinder 41 and the second cylinder 51 will not easily move relative to each other along their central axis, thus completing the fixation of the first cylinder 41 and the second cylinder 51 (the first disassembly structure 4 and the second disassembly structure 5). Conversely, when it is necessary to disassemble the first disassembly structure 4 and the second disassembly structure 5, simply rotate the first cylinder 41 or the second cylinder 51 in the opposite direction to make the limiting member 54 disengage from the positioning groove 43 and the positioning block 42 disengage from the second slide groove 53 and enter the first slide groove 52. Then pull the first cylinder 41 and the second cylinder 51 away from each other until the positioning block 42 is completely disengaged from the first slide groove 52. Thus, the first disassembly structure 4 and the second disassembly structure 5 can be used to achieve either a first usage state where the handle part 1 and the massage part 2 are fixedly assembled with a relatively short length, or a second usage state where the handle part 1, the bent extension part and the massage part 2 are fixedly assembled with a relatively long length.

[0023] The second scenario: Figure 9 and Figure 10As shown, the first disassembly structure 4 includes a first cylinder 41, and the second disassembly structure 5 includes a second cylinder 51. One end of the second cylinder 51 is provided with an opening that matches the size of the first cylinder 41. The inner wall of the opening is provided with at least one first groove 52 along the central axis of the second cylinder 51 from the opening. One side wall of the first groove 52 is provided with a second groove 53 along the circumference of the second cylinder 51. The outer surface of the first cylinder 41 is provided with at least one limiting block 45 that is no larger than the opening size of the first groove 52. The limiting block 45 is press-fitted with the second groove 53. The limiting block 45 may be made of rubber. The limiting block 45 is rectangular or / and L-shaped. When the limiting block 45 is L-shaped, it includes a horizontal part 451 and a vertical part 452. The limiting member 54 is fixedly installed on the bottom surface of the inner wall of the second slide groove 53. The height of the vertical part 452 is greater than the height from the top of the limiting member 54 to the top surface of the inner wall of the second slide groove 53, and less than or equal to the height from the top surface to the bottom surface of the inner wall of the second slide groove 53. Here, we take two first slides 52, two second slides 53, and two limiting blocks 45 as examples for explanation. One limiting block 45 is rectangular, and the other limiting block 45 is L-shaped. When the limiting block 45 is L-shaped, taking the height of the vertical part 452 as equal to the height of the top surface to the bottom surface of the inner wall of the second slide 53 as an example, the limiting block 45 will not move up and down when it is located in the second slide 53. When it is necessary to fix the first disassembly structure 4 and the second disassembly structure 5, align the first cylinder 41 with the opening of the second cylinder 51, and insert the limiting block 45 into the first slide groove 52. Then rotate the first cylinder 41 or the second cylinder 51 in the forward direction so that the limiting block 45 enters the second slide groove 53. When the limiting block 45 is rectangular, the limiting block 45 and the second slide groove 53 are in an interference fit. Thus, when the limiting block 45 is fully inserted into the second slide groove 53, the first cylinder 41 can be stably placed in the second cylinder 51, thereby completing the fixation of the first disassembly structure 4 and the second disassembly structure 5. When the limiting block 45 is L-shaped, since the height of the vertical part 452 is greater than the height from the top of the limiting member 54 to the top surface of the inner wall of the second slide groove 53, and equal to the height from the top surface of the inner wall of the second slide groove 53 to the bottom surface, during the process of the limiting block 45 entering the second slide groove 53, when the vertical part 452 passes through the limiting member 54 and enters the second slide groove 53, the vertical part 452 will only have an interference fit with the second slide groove 53 for a moment. And due to the effect of the limiting member 54, when the vertical part 452 enters the innermost part of the second slide groove 53, it will not easily disengage from the second slide groove 53. Compared with the rectangular limiting block 45, it makes it easier and less effort to rotate the first cylinder 41 or the second cylinder 51 (furthermore, the distance between the limiting member 54 and the inner side wall of the second slide groove 53 can be the width of the vertical part 452, so that when the vertical part 452 enters the second slide groove 53 and passes through the limiting member 54, it can be relatively stable and will not easily generate relative movement). Conversely, when it is necessary to disassemble the first disassembly structure 4 and the second disassembly structure 5, the first cylinder 41 or the second cylinder 51 is rotated in the opposite direction to disengage the limiting block 45 from the second slide groove 53. Then, the first cylinder 41 and the second cylinder 51 are pulled in the opposite direction to disengage the limiting block 45 from the first slide groove 52, thereby completing the disassembly of the first cylinder 41 and the second cylinder 51, that is, completing the disassembly of the first disassembly structure 4 and the second disassembly structure 5. Thus, the first disassembly structure 4 and the second disassembly structure 5 can be used to achieve either a first usage state where the handle part 1 and the massage part 2 are fixedly assembled with a relatively short length, or a second usage state where the handle part 1, the bent extension part and the massage part 2 are fixedly assembled with a relatively long length.

[0024] The third scenario: Figure 11 and Figure 12 As shown, the first disassembly structure 4 includes a first cylinder 41, and the second disassembly structure 5 includes a second cylinder 51. One end of the second cylinder 51 is provided with an opening that matches the size of the first cylinder 41. The inner wall of the opening is provided with an internal thread 56. The outer surface of the first cylinder 41 is provided with a screw-in structure 48, which is an external thread or a fixing block that matches the internal thread 56. When it is necessary to fix the first disassembly structure 4 and the second disassembly structure 5, align the first cylinder 41 with the opening of the second cylinder 51, so that the external thread or fixing block is aligned with the internal thread 56, and rotate the first cylinder 41 or the second cylinder 51 in the forward direction so that the first cylinder 41 gradually enters the second cylinder 51, thereby completing the fixation of the first cylinder 41 and the second cylinder 51, that is, completing the fixation of the first disassembly structure 4 and the second disassembly structure 5. Conversely, when it is necessary to disassemble the first disassembly structure 4 and the second disassembly structure 5, rotate the first cylinder 41 or the second cylinder 51 in the opposite direction so that the first cylinder 41 gradually moves away from the second cylinder 51. Thus, the first disassembly structure 4 and the second disassembly structure 5 can be used to achieve either a first usage state where the handle part 1 and the massage part 2 are fixedly assembled with a relatively short length, or a second usage state where the handle part 1, the bent extension part and the massage part 2 are fixedly assembled with a relatively long length.

[0025] like Figure 13 , Figure 14 and Figure 15 As shown, the first disassembly structure 4 and the second disassembly structure 5 are fixed by snap-fit ​​after docking; Specifically, the first disassembly structure 4 includes a first cylinder 41, with several circumferentially distributed spring pieces 47 fixedly installed at one end of the first cylinder 41. Each spring piece 47 has a vertical section 471 and a protruding section 472 located around the vertical section 471. The second disassembly structure 5 includes a second cylinder 51, with an opening at one end that matches the first cylinder 41 and a fixing groove 55 at the other end. The outer edges of the openings at both ends of the fixing groove 55 are inclined towards its center, which can be set as slopes. The contact surfaces between the protruding section 472 and the outer edges of the openings at both ends of the fixing groove 55 are both set as slopes or arc surfaces. The size of the opening of the fixing groove 55 is greater than or equal to the maximum distance between the two vertical sections 471 and less than the maximum distance between the two protruding sections 472. When it is necessary to fix the first disassembly structure 4 and the second disassembly structure 5, insert the first cylinder 41 into the opening of the second cylinder 51 until the protruding section 472 of the spring piece 47 is in contact with the outer edge of one end opening of the fixing groove 55. Since it is a contact of inclined surfaces with inclined surfaces (or curved surfaces), the spring piece 47 will tilt towards the center of the first cylinder 41 until the protruding section 472 is in contact with the outer edge of the other end opening of the fixing groove 55. At this point, the spring piece 47 returns to its original position, and the first cylinder 41 is stably positioned within the opening of the second cylinder 51 (e.g., Figure 15 As shown in the figure, the fixing of the first disassembly structure 4 and the second disassembly structure 5 is completed; Conversely, when it is necessary to disassemble the first disassembly structure 4 and the second disassembly structure 5, pull the first disassembly structure 4 and the second disassembly structure 5 to make them move in opposite directions. Since the protruding section 472 is in contact with the outer edge of the opening of the fixing groove 55 and is in contact with the inclined surface (or the arc surface), the protruding section 472 will gradually detach from the fixing groove 55 (during this process, the spring piece 47 will tilt towards the center of the first cylinder 41 and then return to its original position), thereby completing the rapid disassembly of the first cylinder 41 and the second cylinder 51, that is, the rapid disassembly of the first disassembly structure 4 and the second disassembly structure 5. Thus, the first disassembly structure 4 and the second disassembly structure 5 can be used to achieve either a first usage state where the handle part 1 and the massage part 2 are fixedly assembled with a relatively short length, or a second usage state where the handle part 1, the bent extension part and the massage part 2 are fixedly assembled with a relatively long length.

[0026] like Figure 2 and Figure 3 As shown, the bending extension includes at least one extension structure 3 (one extension structure 3 is used as an example in the figure). Each extension structure 3 has a first disassembly structure 4 and a second disassembly structure 5 at both ends. When there are two or more extension structures 3, two adjacent extension structures 3 can be detachably and fixedly connected through the first disassembly structure 4 and the second disassembly structure 5.

[0027] like Figure 3 , Figure 16 , Figure 17 and Figure 18As shown, the material of the extension structure 3 is a deformable material. The extension structure 3 includes a deformable support member 31. The first disassembly structure 4 and the second disassembly structure 5 can be detachably and fixedly installed at both ends of the deformable support member 31. Specifically, they can be fixed with screws, which are stable and easy to disassemble and assemble. The deformable support 31 here can be made of plastic bent pipe, plastic bent plate, metal bent pipe, metal bent plate, etc. Taking a plastic bent plate or metal bent plate as an example, after the deformable support 31 is in contact with the first disassembly structure 4 or the second disassembly structure 5, screws can be used to directly fix the deformable support 31 to the first disassembly structure 4 or the second disassembly structure 5. In addition, a slot 6 can be opened at one end of the first disassembly structure 4 and the second disassembly structure 5 (e.g., Figure 17 and Figure 18 As shown, after the deformable support 31 is inserted into the slot 6 for positioning, screws are used to fix the first disassembly structure 4 and the deformable support 31 or the second disassembly structure 5 and the deformable support 31 through them.

[0028] like Figure 3 and Figure 16 As shown, the extension structure 3 also includes a protective sleeve 32, which is fitted around the deformable support 31. By setting the protective sleeve 32, it serves two purposes: firstly, it can prevent external objects from directly contacting and colliding with the deformable support 31 and causing damage to it, and secondly, it can protect the human body from contacting and colliding with the deformable support 31 and causing injury to the human body. On the other hand, it can also wrap the screws to ensure the overall aesthetics.

[0029] like Figure 16 , Figure 17 , Figure 18 and Figure 19 As shown, the fascia gun also includes a limiting structure to prevent the protective sleeve 32 from sliding on the deformable support 31, ensuring stable fixation between the protective sleeve 32 and the deformable support 31. Specifically, the limiting structure includes a recessed portion 7 and a protrusion 322 adapted to the recessed portion 7. The first disassembly structure 4 includes a first connecting portion 49, and the second disassembly structure 5 includes a second connecting portion 57. When the first connecting portion 49 and / or the second connecting portion 57 have at least one recessed portion 7 or a protrusion 322 on their periphery, the inner wall of the protective sleeve 32 has at least one protrusion 322 or a recessed portion 7. When the protective sleeve 32 is fitted around the deformable support 31, the protrusion 322 is located inside the recessed portion 7. Taking the example of a recessed portion 7 on the outer wall of the first connecting portion 49 and the second connecting portion 57, and a protrusion 322 on the inner wall of the protective sleeve 32, when the protective sleeve 32 is fitted around the deformable support member 31, the engagement between the protrusion 322 and the recessed portion 7 ensures that the protective sleeve 32 will not slide freely on the deformable support member 31.

[0030] like Figure 16 , Figure 17 , Figure 18 and Figure 19 As shown, the limiting structure includes a stepped surface (specifically, such as...). Figure 17 The first step surface 491 and Figure 18 The protective sleeve 32 has an opening at both ends and has several inner edges 321 extending toward the center of the opening. When the protective sleeve 32 is fitted around the deformable support 31, each inner edge 321 abuts against a step surface, so that the protective sleeve 32 can be further limited by the protrusion 322 and the recess 7 alone or in combination, so that the protective sleeve 32 will not slide arbitrarily on the deformable support 31.

[0031] like Figure 9 , Figure 11 , Figure 12 and Figure 13 As shown, the outer wall of the first cylinder 41 is provided with a circular groove 44, and a sealing ring 46 is provided in the circular groove 44. The diameter of the sealing ring 46 is larger than the diameter of the first cylinder 41. When the first cylinder 41 is fixed inside the second cylinder 51, the sealing ring 46 acts as an interference fit, making the first cylinder 41 more stable inside the second cylinder 51.
