Description

Technical Field

[0001] This utility model relates to the field of fascia gun technology, and in particular to a pocket fascia gun with an extended handle. Background Technology

[0002] A fascia gun, also known as a deep myofascial impactor, is a soft tissue rehabilitation tool that uses high-frequency impacts to relax the body's soft tissues, effectively relieving muscle tension and achieving pain relief.

[0003] There are two common shapes of fascia guns. One type has a "7"-shaped casing. In this type, the main handle is relatively short, requiring the arm to bend behind the back to allow the massage head to massage the neck and back, making it extremely inconvenient for back massage. The other type, a newer fascia gun with announcement number CN217566740U, has an arc-shaped main body and a handle extension formed by the arc-shaped extension of the main body. While this can simulate arm bending for easier massage of the neck and back, it is less convenient for massaging areas such as the front of the body, like the hands and feet. When the massage head reciprocates, the extra handle extension, motor, and other power components are further from the hand, making it more difficult to hold. Therefore, both types have certain limitations in use. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a pocket fascia gun with an extended handle, so as to solve the problem that the existing figure-7 shaped and arc-shaped fascia guns with extended handles have certain limitations in use.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pocket fascia gun with an extended handle, including a housing, a motor inside the housing, an eccentric wheel fixedly mounted on the output end of the motor, a connecting rod connected to the eccentric shaft of the eccentric wheel via a bearing, a massage head at one end of the connecting rod, and further comprising: Bending extension; Holding part; A connector, one end of which is detachably and fixedly connected to the housing, and the other end of which is detachably and fixedly connected to the grip or the bending extension. When the connector is fixed to the bending extension, the other end of the bending extension is detachably and fixedly connected to the grip.

[0006] Preferably, the connector includes a first rotating column, a second rotating column, a second threaded column, and a positioning column. The first rotating column has a through hole in the middle that is adapted to the second rotating column. The second threaded column and the positioning column are respectively fixed to both ends of the second rotating column and are both smaller than the size of the through hole. The outer surface of the first rotating column has an external thread. The inner wall of the through hole has a convex ring. One end of the second threaded column passes through the convex ring and the through hole and is screwed to the gripping part or the bending extension. When the connector is fixed to the housing, the convex ring abuts against the first rotating column.

[0007] Preferably, the bottom of the housing has a bottom opening, and a fixing block is provided inside the housing near the bottom opening. The fixing block has a positioning groove adapted to the positioning post and a threaded groove adapted to the external thread of the outer surface of the first rotating post, which are opened sequentially from the inside to the outside at the end opposite to the bottom opening.

[0008] Preferably, when the second threaded post is fixed to the bent extension or the gripping part, there is a gap between the first rotating post and the bent extension or the gripping part.

[0009] Preferably, the housing contains an L-shaped battery, which includes a horizontal part and a vertical part. The horizontal part is located between the motor and the fixing block, and the vertical part is located on one side of the motor.

[0010] Preferably, one end of the bent extension is provided with a first threaded post that is the same as the second threaded post, and the other end is provided with a second threaded hole that is adapted to the second threaded post; one end of the gripping part is provided with a first threaded hole that is adapted to the first threaded post.

[0011] Preferably, the gripping part is hollow inside, and both ends are provided with openings larger than the size of the first threaded post. A connecting block can be detachably and fixedly installed inside the gripping part near one of the openings. The connecting block has a first threaded hole that is adapted to the first threaded post through one end facing the opening. A cover can be detachably and fixedly installed at the other end of the gripping part.

[0012] Preferably, the positioning post has a polygonal cross-section, and one end of the positioning post protrudes from the through hole.

[0013] Compared with the prior art, the beneficial effects that this utility model can achieve are: By fixing one end of the bending extension to the grip, then fixing one end of the connector to the other end of the bending extension, and finally fixing the other end of the connector to the housing, it is convenient to massage the neck and back. Conversely, when massaging the front of the body, such as the hands and feet, one end of the connector is fixed to the grip, and then the other end of the connector is fixed to the housing. This shortens the distance between the motor and other power components and the massage head and the user's hand. Therefore, the fascia gun is easier to hold when in use. The two working states of the fascia gun can be switched and assembled according to the user's needs, making it more applicable. Attached Figure Description

[0015] 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.

[0016] like Figures 1-5 As shown, this utility model provides a pocket fascia gun with an extended handle, including a housing 1, a motor 4 inside the housing 1, an eccentric wheel 5 fixedly installed at the output end of the motor 4, a connecting rod 6 connected to the eccentric shaft of the eccentric wheel 5 through a bearing, a massage head 7 at one end of the connecting rod 6, and also includes a bending extension 3, a gripping part 2 and a connecting piece 8. The bending extension 3 here can be set as an arc shape. One end of the connector 8 is detachably and fixedly connected to the housing 1, and the other end of the connector 8 is detachably and fixedly connected to the gripping part 2 or the bending extension part 3. When the connector 8 is fixed to the bending extension part 3, the other end of the bending extension part 3 is detachably and fixedly connected to the gripping part 2. When massaging areas such as the neck and back is needed, one end of the bent extension 3 and the grip 2 are fixed, then one end of the connector 8 is fixed to the other end of the bent extension 3, and finally the other end of the connector 8 is fixed to the housing 1, and the whole assembly is completed. Figure 1 As shown, this makes it convenient to massage the neck and back. Conversely, when it is necessary to massage the front of the body, such as the hands and feet, one end of the connector 8 is fixed to the grip 2, and the other end of the connector 8 is fixed to the housing 1. This shortens the distance between the motor 4 and other power parts and the massage head 7 and the user's hand. Therefore, when the fascia gun is working, it is relatively easier for people to hold it. The two working states of the fascia gun can be switched and assembled according to people's needs, making it more applicable. The specific principle of using motor 4 to drive the massage head 7 in a reciprocating tapping motion is existing technology and will not be elaborated here.

[0017] like Figure 3 and Figure 4 As shown, the connector 8 includes a first rotating post 81, a second rotating post 82, a second threaded post 83, and a positioning post 84. The first rotating post 81 has a through hole 812 that is adapted to the second rotating post 82. The second threaded post 83 and the positioning post 84 are respectively fixed at both ends of the second rotating post 82 and are both smaller than the size of the through hole 812. The outer surface of the first rotating post 81 has an external thread 811. The inner wall of the through hole 812 has a convex ring 813. One end of the second threaded post 83 passes through the convex ring 813 and the through hole 812 and is screwed to the gripping part 2 or the bent extension part 3. When the connector 8 is fixed to the housing 1, the convex ring 813 abuts against the first rotating post 81. The bottom of the housing 1 has a bottom opening, and a fixing block 10 is provided inside the housing 1 near the bottom opening. The fixing block 10 has a positioning groove 101 adapted to the positioning post 84 and a thread groove 102 adapted to the external thread 811 on the outer surface of the first rotating post 81, which are opened sequentially from the inside to the outside of the bottom opening. Specifically, the fixing principle of the connector 8 to the bent extension 3 or the gripping part 2 and the housing 1 is as follows: First, thread one end of the second threaded post 83 passes through the convex ring 813 and the through hole 812 and is screwed to the gripping part 2 or the bent extension part 3 for fixation. Then, align one end of the positioning post 84 with the positioning groove 101 for initial positioning but not fully inserted (when the bent extension part 3 is fixed to the housing 1, the arc-shaped bent extension part 3 and the massage head 7 are in the same plane, and the arc-shaped opening of the bent extension part 3 faces the massage head 7, such as...). Figure 1As shown), rotate the first rotating column 81 to gradually enter the thread groove 102. Then, the convex ring 813 abuts against the second rotating column 82 and simultaneously drives the positioning column 84 to gradually penetrate into the positioning groove 101 until the other end of the second rotating column 82 abuts against the fixing block 10, so that the second rotating column 82 will not move in the through hole 812, ensuring the stability of the connection 8 and the housing 1. In this way, the fixing of the housing 1 and the bending extension 3 or the gripping part 2 can be completed. When the second threaded post 83 is fixed to the bending extension 3, the bending extension 3 can be fixed to the gripping part 2 before being fixed to the second threaded post 83, or the bending extension 3 can be fixed to the gripping part 2 first, and then the second threaded post 83 can be fixed to the bending extension 3. By fixing the part in this way, on the one hand, it is ensured that the curved bending extension 3 and the massage head 7 are in the same plane, and the curved opening of the bending extension 3 faces the massage head 7, ensuring the overall aesthetics. On the other hand, it avoids the trouble of fixing the part to the housing 1 by directly rotating the bending extension 3 or the grip 2 (for example, because the bending extension 3 or the grip 2 is relatively long and the housing 1 is relatively large, direct rotation is more difficult than rotating the first rotating column 81 and the second rotating column 82).

[0018] like Figures 1-4 As shown, when the second threaded post 83 is fixed to the bent extension 3 or the gripping part 2, there is a gap between the first rotating post 81 and the bent extension 3 or the gripping part 2. This design ensures smoother rotation of the first rotating column 81, preventing friction from contacting the bending extension 3 or the gripping part 2.

[0019] like Figure 3 As shown, an L-shaped battery 9 is provided inside the housing 1. The L-shaped battery 9 includes a horizontal part and a vertical part. The horizontal part is located between the motor 4 and the fixing block 10, and the vertical part is located on one side of the motor 4. By setting up an L-shaped battery 9, the utilization rate of the empty space inside the housing 1 is fully improved on the one hand, and the battery capacity is increased on the other hand, so that the fascia gun can be used for a longer time after a single charge.

[0020] like Figure 1 , Figure 3 and Figure 5 As shown, one end of the bending extension 3 is provided with a first threaded post 31 that is the same as the second threaded post 83, and the other end is provided with a second threaded hole 32 that is adapted to the second threaded post 83. One end of the gripping part 2 is provided with a first threaded hole 22 that is adapted to the first threaded post 31. This arrangement facilitates the fixing and disassembly of both ends of the bending extension 3 to the housing 1 and the gripping part 2, respectively, as well as the fixing and disassembly of the housing 1 and the gripping part 2.

[0021] like Figure 2As shown, the gripping part 2 is hollow inside, and both ends are provided with openings larger than the first threaded post 31. A connecting block 21 can be detachably and fixedly installed inside the gripping part 2 near one of the openings (specifically, it can be fixed by screws). The connecting block 21 has a first threaded hole 22 that is adapted to the first threaded post 31 through one end facing the opening. The other end of the gripping part 2 is detachably and fixedly installed with a cover 23, specifically, it can be fixed by screws. By designing the grip 2 in this way, the overall weight can be reduced. With the detachable connecting block 21 and cover 23, when the first threaded hole 22 of the connecting block 21 is worn or damaged during use, it is convenient to replace it separately, avoiding the need to replace the entire grip 2.

[0022] like Figure 3 and Figure 4 As shown, the cross-section of the positioning post 84 is polygonal, and one end of the positioning post 84 protrudes from the through hole 812. This arrangement facilitates the rotation of the second rotating post 82 and the second threaded post 83 by holding and rotating the positioning post 84, thereby fixing the second threaded post 83 to the holding part 2 or the bent extension part 3. In addition, it can also ensure that the positioning post 84 is inserted into the positioning groove 101, and that there will be no relative rotation between the positioning post 84 (the bent extension part 3 or the holding part 2 fixed to the second threaded post 83) and the positioning groove 101 when the first rotating post 81 is rotated.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
