However, the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without making any creative work all fall within the scope of protection of the present invention.

[0034] like Figure 1-Figure 8 As shown, the utility model provides a fascia gun with a handle extension function, including a handle portion 1 and a massage portion 2, a transmission mechanism is arranged in the massage portion 2, and the specific transmission mechanism includes a motor and a cam reciprocating motion structure, which is an existing structure for the movement of the fascia gun, and the specific working principle is not repeated here, a power supply is arranged in the handle portion 1, and the fascia gun also includes at least one bending extension portion 3, a first connection structure 4 and a second connection structure 5 are respectively arranged at both ends of the bending extension portion 3, a first connection structure 4 is arranged at one end of the massage portion 2, and a second connection structure 5 is arranged at one end of the handle portion 1, the first connection structure 4 and the second connection structure 5 are detachably fixedly connected, a probe 7 is arranged on the first connection structure 4, and a conductive sheet 6 is arranged on the second connection structure 5, the probes 7 on the first connection structure 4 at both ends of the bending extension portion 3 and the conductive sheet 6 on the second connection structure 5 are connected by wires, and when the first connection structure 4 and the second connection structure 5 are fixedly connected, the probe 7 and the conductive sheet 6 are in contact electrical connection;

[0035] The power supply in the handle part 1 is electrically connected to the conductive sheet 6 on the second connection structure 5 thereon through a wire, and the transmission mechanism in the massage part 2 is electrically connected to the probe 7 on the first connection structure 4 thereon through a wire;

[0036] By making the structures of the joints between the handle portion 1 and the bent extension portion 3, the joints between the bent extension portion 3 and the massage portion 2, and the joints between the handle portion 1 and the massage portion 2 consistent, the handle portion 1 can be used alone in combination with the massage portion 2, or the handle portion 1 and the bent extension portion 3 can be assembled and then used in combination with the massage portion 2;

[0037] By providing the bending extension part 3, when it is necessary to massage any part of the back of a person, the massage part 2 and the handle part 1 can be separated first, and then one end of the bending extension part 3 is fixed to the massage part 2, and the other end of the bending extension part 3 is fixed to the handle part 1, which is equivalent to extending the handle part 1, thereby effectively expanding the area and range of massage by the user using the fascia gun, avoiding the trouble of the user being inconvenient to use or unable to reach certain massage positions when massaging muscles in certain specific parts;

[0038] In addition, after assembling the upper bending extension portion 3, and when the handle portion 1 is used alone and assembled with the massage portion 2, since the first connecting structure 4 and the second connecting structure 5 are fixedly connected (the docking between the handle portion 1 and the bending extension portion 3, the docking between the bending extension portion 3 and the massage portion 2, and the docking between the handle portion 1 and the massage portion 2), the probe 7 and the conductive sheet 6 are in contact electrical connection, and the power supply in the handle portion 1 is electrically connected to the conductive sheet 6 on the second connecting structure 5 thereon through a wire, and the transmission mechanism in the massage portion 2 is electrically connected to the probe 7 on the first connecting structure 4 thereon through a wire, thereby ensuring that no matter when the handle portion 1 is used in combination with the massage portion 2, or when the handle portion 1 and the bending extension portion 3 are assembled and then used in combination with the massage portion 2, the power supply can be kept to supply power to the transmission mechanism, thereby ensuring the normal performance of the massage action.

[0039] like Figure 1-Figure 3 As shown, the material of the bending extension part 3 is a deformable material, specifically rubber or soft metal material (such as a gooseneck tube), so that the bending angle adjustment range of the bending extension part 3 is wider, thereby further meeting the massage needs of different parts of different people, reducing the discomfort of human arm joint activities, and being more applicable.

[0040] The specific detachable fixed connection structures of the first connection structure 4 and the second connection structure 5 can be selected from the following:

[0041] Embodiment 1:

[0042] like Figure 4-Figure 8 As shown, the second connection structure 5 includes a second cylinder 51, and a conductive sheet 6 (which can be set as a copper sheet here) is fixed at one end of the second cylinder 51. The first connection structure 4 includes a first cylinder 41, and an opening that matches the size of the second cylinder 51 is opened at one end of the first cylinder 41. A plurality of probes 7 are fixed on the circumference of the bottom surface of the inner wall of the opening. At least one positioning block 42 is fixed on one side of the inner wall of the opening. The positioning block 42 is provided with a positioning groove 43 along the central axis direction of the first cylinder 41 on the side facing away from it and abutting against the inner wall of the opening. The outer edge of the second cylinder 51 is along A first slide groove 52 not less than the size of the positioning block 42 is provided in the axial direction thereof, a second slide groove 53 is provided in the outer edge of one end surface of the second cylinder 51 facing away from the conductive sheet 6 along the axial direction thereof, the second slide groove 53 is connected with the first slide groove 52 in an L shape, a stopper 54 is provided on the inner wall of the second slide groove 53, the second cylinder 51 rotates relatively after entering the first cylinder 41, when the positioning block 42 moves from the first slide groove 52 to the second slide groove 53, the stopper 54 moves into the positioning groove 43, and the positioning block 42 fits with the inner wall of the second slide groove 53;

[0043] The limiting member 54 is a spring positioning bead or / and a rubber strip;

[0044] Here, two positioning blocks 42 and two limiting members 54 are used as an example to illustrate: one is set as a spring positioning bead and the other is set as a rubber strip.

[0045] When the first connection structure 4 and the second connection structure 5 need to be fixed, align one end of the second cylinder 51 fixing the conductive sheet 6 with the opening of the first cylinder 41, and align the positioning block 42 with the first slide groove 52 and insert it until the positioning block 42 is directly opposite to the second slide groove 53, and the probe 7 is in contact with the conductive sheet 6, and then the first cylinder 41 or the second cylinder 51 is rotated forwardly so that the positioning block 42 can enter the second slide groove 53;

[0046] When the limiting member 54 is a spring positioning bead, when the first cylinder 41 or the second cylinder 51 is rotated in the forward direction, the positioning block 42 squeezes the spring positioning bead until the spring positioning bead is finally located in the positioning groove 43, so that 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 fits with the inner wall of the second slide groove 53, and at this time, the first cylinder 41 and the second cylinder 51 will not easily move relative to each other along the axis direction, that is, the first cylinder 41 and the second cylinder 51 are fixed (at this time, the probe 7 and the conductive sheet 6 are still in contact);

[0047] When the stopper 54 is a rubber strip, when the first cylinder 41 or the second cylinder 51 is rotated in the positive 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, and because the stopper 54 moves into the positioning groove 43, the positioning block 42 fits with the inner wall of the second slide groove 53, and at this time, the first cylinder 41 and the second cylinder 51 will not easily move relative to each other along the axis direction thereof, that is, the first cylinder 41 and the second cylinder 51 (the first connecting structure 4 and the second connecting structure 5) are fixed (at this time, the probe 7 and the conductive sheet 6 are still in contact);

[0048] On the contrary, when the first connection structure 4 and the second connection structure 5 need to be separated, the first cylinder 41 or the second cylinder 51 can be rotated in the opposite direction with force, so that the limiter 54 is separated from the positioning groove 43, the positioning block 42 is separated from the second slide groove 53 and enters the first slide groove 52, and then the first cylinder 41 and the second cylinder 51 are pulled away from each other until the positioning block 42 is completely separated from the first slide groove 52;

[0049] like Figure 7 and Figure 8 As shown, a plurality of stops 44 are distributed circumferentially on the bottom surface of the inner wall of the opening of the first cylinder 41. The gap between the stops 44 and the probe 7 is the thickness of the conductive sheet 6, which plays a certain limiting and guiding role in the movement of the conductive sheet 6, so that during the rotation of the first cylinder 41 or the second cylinder 51, the conductive sheet 6 is always in contact with the stops 44 and the probe 7.

[0050] Embodiment 2:

[0051] like Fig. 9 and Fig.10 As shown, the second connection structure 5 includes a second cylinder 51, one end of the second cylinder 51 is provided with an opening adapted to the size of the first cylinder 41, the inner wall of the opening is provided with at least one first slide groove 52 along the central axis direction of the second cylinder 51 from the opening, and a side wall of the first slide groove 52 is provided with a second slide groove 53 along the circumferential direction of the second cylinder 51, and the first connection structure 4 includes a first cylinder 41, and the outer surface of the first cylinder 41 is provided with at least one stopper 46 not larger than the opening size of the first slide groove 52, the stopper 46 and the second slide groove 53 are interference fit, and the stopper 46 can be made of rubber material;

[0052] The limit block 46 is rectangular or / and L-shaped. When the limit block 46 is L-shaped, it includes a horizontal portion 461 and a vertical portion 462. The limit member 54 is fixedly installed on the bottom surface of the inner wall of the second slide groove 53. The height of the vertical portion 462 is greater than the height from the top of the limit member 54 to the top surface of the inner wall of the second slide groove 53, and is less than or equal to the height from the top surface of the inner wall of the second slide groove 53 to the bottom surface.

[0053] Here, four first slide grooves 52, four second slide grooves 53 and four limit blocks 46 are taken as examples for description, wherein two limit blocks 46 are rectangular, and two limit blocks 46 are L-shaped. When the limit blocks 46 are L-shaped, taking the height of the vertical portion 462 equal to the height of the top surface of the inner wall of the second slide groove 53 to the bottom surface as an example, the limit blocks 46 will not move up and down when they are located in the second slide groove 53;

[0054] When the first connection structure 4 and the second connection structure 5 need to be fixed, the first cylinder 41 is aligned with the opening of the second cylinder 51, and the limit block 46 is aligned with the first slide groove 52 and inserted, and then the first cylinder 41 or the second cylinder 51 is rotated forward to make the limit block 46 enter the second slide groove 53;

[0055] When the stop block 46 is rectangular, the stop block 46 and the second slide groove 53 are interference fit, so that when the stop block 46 completely enters the second slide groove 53, the first cylinder 41 can be stably located in the second cylinder 51, that is, the first connecting structure 4 and the second connecting structure 5 are fixed;

[0056] When the stop block 46 is L-shaped, since the height of the vertical portion 462 is greater than the height from the top of the stop member 54 to the top surface of the inner wall of the second slide groove 53, and is 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 stop block 46 entering the second slide groove 53, when the vertical portion 462 passes through the stop member 54 and enters the second slide groove 53, the vertical portion 462 will only be in interference fit with the second slide groove 53 for a moment, and due to the action of the stop member 54, when the vertical portion 462 enters the innermost part of the second slide groove 53, it will not easily disengage from the second slide groove 53, which makes it easier to rotate the first cylinder 41 or the second cylinder 51 compared to the rectangular stop block 46 (further, the distance between the stop member 54 and the inner side wall of the second slide groove 53 can be the width of the vertical portion 462, so that when the vertical portion 462 enters the second slide groove 53 and passes through the stop member 54, it can be relatively stable and will not easily move left and right).

[0057] On the contrary, when it is necessary to separate the first connecting structure 4 and the second connecting structure 5, the first cylinder 41 or the second cylinder 51 is rotated in the opposite direction to disengage the limit block 46 from the second slide groove 53, and then the first cylinder 41 and the second cylinder 51 are pulled in the opposite direction to disengage the limit block 46 from the first slide groove 52, thereby completing the separation of the first cylinder 41 and the second cylinder 51, that is, completing the separation of the first connecting structure 4 and the second connecting structure 5.

[0058] Embodiment three:

[0059] like Fig.11 and Fig.12 As shown, the first connection structure 4 includes a first cylinder 41, and the second connection 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, and 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-on structure 49, and the screw-on structure 49 is an external thread or a fixing block that matches the internal thread 56.

[0060] When the first connection structure 4 and the second connection structure 5 need to be fixed, the first cylinder 41 is aligned with the opening of the second cylinder 51, so that the external thread or the fixing block is directly opposite to the internal thread 56, and the first cylinder 41 or the second cylinder 51 is rotated forward so that the first cylinder 41 gradually enters the second cylinder 51, thereby completing the fixing of the first cylinder 41 and the second cylinder 51, that is, completing the fixing of the first connection structure 4 and the second connection structure 5;

[0061] On the contrary, when the first connection structure 4 and the second connection structure 5 need to be separated, the first cylinder 41 or the second cylinder 51 is rotated in the opposite direction so that the first cylinder 41 gradually moves away from the second cylinder 51 .

[0062] Embodiment 4:

[0063] like Fig.13 , Fig.14 and Fig.15 As shown, the first connection structure 4 includes a first cylinder 41, and a plurality of circumferentially distributed spring pieces 48 are fixedly installed at one end of the first cylinder 41. The spring piece 48 has a vertical section 481 and a protruding section 482 arranged on the periphery of the vertical section 481. The second connection structure 5 includes a second cylinder 51. An opening adapted to the first cylinder 41 is opened at one end of the second cylinder 51, and a fixing groove 55 is opened at the other end. The outer edges of the openings at both ends of the fixing groove 55 are inclined toward the center thereof, which can be set as inclined surfaces. The contact surfaces between the protruding section 482 and the outer edges of the openings at both ends of the fixing groove 55 are set as inclined surfaces or arc surfaces. The opening size of the fixing groove 55 is greater than or equal to the maximum distance between the two vertical sections 481, and less than the maximum distance between the two protruding sections 482.

[0064] When the first connection structure 4 and the second connection structure 5 need to be fixed, the first cylinder 41 is aligned with the opening of the second cylinder 51 and inserted until the protruding section 482 of the spring sheet 48 fits with the outer edge of the opening at one end of the fixing groove 55. Since the inclined surface is in contact with the inclined surface (or arc surface), the spring sheet 48 will tilt toward the center of the first cylinder 41 until the protruding section 482 fits with the outer edge of the opening at the other end of the fixing groove 55. Here, the spring sheet 48 is reset, and the first cylinder 41 is stably located in the opening of the second cylinder 51 (such as Fig.15 As shown), the fixing of the first connecting structure 4 and the second connecting structure 5 is completed;

[0065] On the contrary, when it is necessary to disassemble the first connecting structure 4 and the second connecting structure 5, the first connecting structure 4 and the second connecting structure 5 are pulled forcefully to make them move in opposite directions. Since the protruding section 482 is in contact with the outer edge of the opening of the fixing groove 55, and the inclined surfaces (or arc surfaces) are in contact with each other, the protruding section 482 will gradually separate from the fixing groove 55 (in this process, the spring piece 48 will tilt toward the center of the first cylinder 41 and then reset), thereby completing the rapid disassembly of the first cylinder 41 and the second cylinder 51, that is, the rapid disassembly of the first connecting structure 4 and the second connecting structure 5.

[0066] like Figure 7 , Fig. 9 , Fig.11 , Fig.12 and Fig.13 As shown, a circular groove 45 is provided on the outer wall of the first cylinder 41, and a sealing ring 47 is provided in the circular groove 45. The diameter of the sealing ring 47 is larger than the diameter of the first cylinder 41;

[0067] When the first cylinder 41 is inserted into the second cylinder 51 and fixed, the sealing ring 47 plays a role of interference fit, so that the first cylinder 41 is fixed in the second cylinder 51 more stably.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
