[0015] In general, compared with the prior art, the above technical solution conceived by the present invention has the following beneficial effects: 1. The portable fascia gun and the method of using the same of the present invention, through the arranged massage components, the user first turns on the switch of the built-in motor, so that the built-in motor can drive the short shaft and the eccentric wheel to rotate as a whole, and when the eccentric wheel rotates as a whole, it can drive the ball head seat to rotate as a whole, and when the ball head seat rotates as a whole, it can drive the connecting rod and the massage rod to move in the up and down directions as a whole, and then can drive the massage connecting piece to move in the up and down directions as a whole, and the arranged lower ball head and upper ball head can rotate in the connecting seat, which can make the eccentric wheel rotate as a whole due to the rotation of the eccentric wheel. The excessive rotation may cause the connecting rod and the massage rod to be suffocated. On the other hand, the lower ball head can be adaptively rolled while the eccentric wheel is rotating, so as to reduce the kinetic energy loss when the connecting rod and the ball head seat are mutually transmitted. Compared with directly connecting the connecting rod with the ball head seat for rotation, the loss of the connecting rod can be greatly reduced, and the service life of the massage component as a whole can be indirectly increased. In addition, the arrangement of the ball head groove can also have a benefit effect that it is convenient to inject wear-resistant oil or other lubricants into the gap between the lower ball head and the ball head groove, so as to further reduce the kinetic energy loss when the connecting rod and the ball head seat are transmitted. 2. The portable fascia gun and the method of using the same of the present invention, through the arranged locking piece, when the unlocking member is at the highest position, the interference wheel is in mutual interference with the first fitting plane, and in the process of the mutual interference between the interference wheel and the first fitting plane, the first spring is in a compressed state and a part of the insertion rod is inserted out of the gun shell, and then after the unlocking member is operated to move downward as a whole, the interference wheel can quickly slide off the first fitting plane, and because the first fitting plane loses its obstruction, the first spring can perform a short elastic reset, and can push the follower plate to move a certain distance as a whole, and the second fitting plane also moves a certain distance synchronously at this time, and when the second fitting plane and the interference wheel contact each other, the follower plate can be locked on the interference wheel for a second time; 3. The portable fascia gun and the method of using the same of the present invention can synchronously displace the impact base by a certain distance through the arranged impact piece after the follower plate as a whole moves a certain distance. At this time, the second bevel gear can simultaneously displace a certain distance so that the second bevel gear and the first bevel gear are meshed with each other. After the second bevel gear is meshed with the first bevel gear, the output end of the built-in motor can drive the first bevel gear and the second bevel gear to rotate when it rotates. After the second bevel gear rotates, it can drive the cam to rotate. After the cam rotates, when the raised section of the cam touches the first impact wheel, it can push the first impact wheel to move backward to drive the second impact wheel to move backward, so that the second impact wheel can be driven backward. The second impact wheel strikes the gun housing. After the second impact wheel strikes the gun housing, since the gun housing is connected to the massage component, impurities in the gun housing and the massage component can be loosened. On the one hand, it can effectively prevent the impurities from adhering to the inner wall of the gun housing. On the other hand, it can effectively prevent the impurities from staying in the gap between the shaft barrel and the massage rod, so that the smoothness of the massage rod when it is extended from the shaft barrel is improved. On the other hand, by striking and loosening the impurities in the gap between the massage rod and the shaft barrel, the resistance of the massage rod extending in the shaft barrel can be reduced, so as to further reduce the kinetic energy loss when the kinetic energy is transmitted between the ball head seat and the connecting rod. In addition, the life of the massage rod when it is used for a long time can be further extended. 4. The portable fascia gun and its use method of the present invention, through the arranged impact member, the second impact wheel is in conflict with the inner wall of the gun case when it is in the initial state, at this time the buffer shaft is inserted deeper into the impact rod and the second spring is in a compressed state, as the impact base moves to the right, at this time the second impact wheel also moves to the right, so the second spring loses the limit of the unlocking member, so the second spring can push the second impact wheel to move slightly to the left, on the one hand, it can effectively prevent the second impact wheel from being too far away from the inner wall of the gun case when moving to the right, so that the second impact wheel cannot hit the inner wall of the gun case, and can make the second impact wheel always touch the inner wall of the gun case in the process of the first impact wheel driving the second impact wheel to move left, on the other hand, it can make the first impact wheel further buffer when driving the second impact wheel to move left and touch the inner wall of the gun case, so as to prevent the second impact wheel from touching the gun case with too much force, causing the gun case as a whole to shake violently; 5. The portable fascia gun and the method of using the same of the present invention, through the arranged unlocking member, when the unlocking member is moved downward, the second pull rings located on the left and right sides are first pulled toward the left and right ends to make the locking rods located on both sides disengage from the countersunk holes, at this time, the rebound plate can squeeze the third spring for compression, and then push the first pull ring to make the unlocking rod move downward as a whole, and when the unlocking member can drive the follow-up impact member to generate linkage with the massage member, at this time, the second pull ring is pulled to make the locking rod re-enter the countersunk hole to complete the re-positioning of the unlocking rod; 6. The portable fascia gun and the method of using the same of the present invention can penetrate into the airbag box and squeeze the airbag in the airbag box through the arranged downward moving rod during the rapid downward movement of the downward moving rod. On the one hand, it can buffer the downward movement of the resistance wheel to prevent the resistance wheel from moving down too quickly, which would cause the resistance wheel to quickly slide off the second fitting plane and make it difficult for the follow-up impact component to fall off from the massage component and fail to link. On the other hand, it can compress the airbag to inflate the airbag so that the gas penetrates into the gun housing, and dissipate heat for the components in the gun housing and the massage component. On the other hand, it can blow the impurities in the gun housing and the massage component to loosen the impurities in the gap between the shaft cylinder and the massage rod, so as to further promote the removal of impurities in the gap between the shaft cylinder and the massage rod by the follow-up impact component.

[0021] In the embodiment, Figure 1-12 A portable fascia gun is provided, which includes a gunstock 1, on which a gun shell 11 is detachably mounted, a built-in cavity is provided in the gun shell 11, and a built-in battery 12 is detachably mounted in the gunstock 1; a massage component 2, which is detachably mounted in the built-in cavity of the gun shell 11; a massage connector 3, which is removably arranged in the massage component 2, and the massage connector 3 can be driven by the massage component 2, and the massage connector 3 includes a massage seat 31, on which a massage sleeve 32 is detachably mounted, and the massage sleeve 32 is detachably connected to the massage component 2; a concave shaft 33, on both ends of which a massage wheel 34 is detachably mounted, and two groups of massage wheels 34 are rotatably connected to the massage seat 31, and a rubber sleeve 35 is detachably mounted on the two groups of massage wheels 34; a follow-up impact component 4, which is detachably mounted The gun body 11 is detachably mounted in the gun housing 11, and is composed of a locking member and a striking member connected to the locking member; an unlocking member 5 is detachably mounted on the gun housing 11, and the unlocking member 5 conflicts with the locking member in the initial position; wherein the follower striking member 4 can be converted between a locked state and an unlocked state; when the unlocking member 5 is located at the highest position in the initial state, the unlocking member 5 conflicts with the locking member, so that the follower striking member 4 is in a locked state; when the unlocking member 5 moves downward, the unlocking member 5 and the locking member can be disengaged first and then conflicted for the second time, so that the follower striking member 4 is in an unlocked state, and when the follower striking member 4 is in the unlocked state, it can be linked with the massage member 2, and when the follower striking member 4 is in a moving state, it can form an impact operation on the gun housing 11.

[0022] The present invention is based on an overall idea that, through the arranged massage component 2, the user first turns on the switch of the built-in motor 21, so that the built-in motor 21 can drive the short shaft 24 and the eccentric wheel 25 to rotate as a whole, and when the eccentric wheel 25 rotates as a whole, it can drive the ball head seat 26 to rotate as a whole, and when the ball head seat 26 rotates as a whole, it can drive the connecting rod 291 and the massage rod 29 to move in the up and down direction as a whole, and then can drive the massage connecting piece 3 to move in the up and down direction as a whole, and the arranged lower ball head 292 and upper ball head 293 can rotate in the connecting seat 28, which can make the eccentric wheel 25 rotate as a whole due to the rotation. On the other hand, the eccentric wheel 25 can rotate so fast that the connecting rod 291 and the massage rod 29 are suffocated. On the other hand, the lower ball head 292 can be adaptively rolled while the eccentric wheel 25 is rotating, so as to reduce the kinetic energy loss when the connecting rod 291 and the ball head seat 26 are mutually transmitted. Compared with directly connecting the connecting rod 291 with the ball head seat 26 for rotation, the loss of the connecting rod 291 can be greatly reduced, and the life of the massage component 2 as a whole can be indirectly improved during use. In addition, the arrangement of the ball head groove can also have a benefit effect that it is convenient to inject wear-resistant oil or other lubricants into the gap between the lower ball head 292 and the ball head groove, so as to further reduce the kinetic energy loss when the connecting rod 291 and the ball head seat 26 are transmitted. By means of the arranged locking piece, when the unlocking member 5 is at the highest position, the abutting wheel 59 abuts against the first fitting plane 46, and in the process of the abutting wheel 59 abutting against the first fitting plane 46, the first spring 43 is in a compressed state and a part of the inserting rod 42 is inserted out of the gun housing 11. Then, after the unlocking member 5 is operated to move downward as a whole, the abutting wheel 59 can quickly slide off the first fitting plane 46. Since the first fitting plane 46 loses its obstruction, the first spring 43 can perform a short elastic reset, and can push the follower plate 45 to move a certain distance as a whole. At this time, the second fitting plane 47 also moves a certain distance synchronously. When the second fitting plane 47 and the abutting wheel 59 contact each other, the follower plate 45 can be locked on the abutting wheel 59 for a second time. By means of the arranged impact members, when the follower plate 45 moves a certain distance as a whole, the impact base 48 can be synchronously displaced a certain distance. At this time, the second bevel gear 493 can be simultaneously displaced a certain distance so that the second bevel gear 493 and the first bevel gear 23 are meshed with each other. After the second bevel gear 493 is meshed with the first bevel gear 23, the output end of the built-in motor 21 can drive the first bevel gear 23 and the second bevel gear 493 to rotate when it rotates. After the second bevel gear 493 rotates, the cam 492 can be driven to rotate. After the cam 492 rotates, when the raised section of the cam 492 touches the first impact wheel 483, the first impact wheel 483 can be pushed to move backward to drive the second impact wheel 486 to move backward, so that the second impact wheel 486 can impact the gun housing 1 1. After the second impact wheel 486 impacts the gun housing 11, since the gun housing 11 is connected to the massage component 2, the impurities in the gun housing 11 and the massage component 2 can be loosened, which can effectively prevent the impurities from adhering to the inner wall of the gun housing 11, and can effectively prevent the impurities from staying in the gap between the shaft cylinder 27 and the massage rod 29, so that the smoothness of the massage rod 29 when it is extended from the shaft cylinder 27 is improved. On the other hand, by impacting and loosening the impurities in the gap between the massage rod 29 and the shaft cylinder 27, the resistance of the massage rod 29 to extend in the shaft cylinder 27 can be reduced, so as to further reduce the kinetic energy loss when the kinetic energy is transmitted between the ball head seat 26 and the connecting rod 291, and can further extend the life of the massage rod 29 when it is used for a long time; By means of the arranged striking piece, the second striking wheel 486 is in conflict with the inner wall of the gun housing 11 when it is in the initial state. At this time, the buffer shaft 484 is inserted deeper into the striking rod 481 and the second spring 4811 is in a compressed state. As the striking base 48 moves to the right, the second striking wheel 486 also moves to the right. Therefore, the second spring 4811 loses the limit of the unlocking member 5. Therefore, the second spring 4811 can push the second striking wheel 486 to move slightly to the left. On the one hand, it can effectively prevent the second striking wheel 486 from moving to the left. When moving right, the distance between the second impact wheel 486 and the inner wall of the gun case 11 is too large, so that the second impact wheel 486 cannot impact the inner wall of the gun case 11, so that the second impact wheel 486 can always touch the inner wall of the gun case 11 when the first impact wheel 483 drives the second impact wheel 486 to move left. On the other hand, the first impact wheel 483 can further buffer when driving the second impact wheel 486 to move left and touch the inner wall of the gun case 11, so as to prevent the second impact wheel 486 from hitting the gun case 11 too hard and causing the gun case 11 to shake violently as a whole; Through the arranged unlocking member 5, when the unlocking member 5 is moved downward, the second pull rings 58 on the left and right sides are first pulled toward the left and right ends to make the locking rods 55 on both sides disengage from the countersunk holes 521. At this time, the rebound plate 56 can squeeze the third spring 57 for compression, and then push the first pull ring 522 to make the unlocking rod 52 move downward as a whole. After the unlocking member 5 can drive the follow-up impact member 4 to generate linkage with the massage member 2, the second pull ring 58 is pulled to make the locking rod 55 re-enter the countersunk hole 521 to complete the re-positioning of the unlocking rod 52. The downward moving rod 591 is arranged so that it can penetrate into the airbag box 211 during the rapid downward movement of the downward moving rod 591 and squeeze the airbag in the airbag box 211. On the one hand, it can buffer the downward movement of the resistance wheel 59 to prevent the resistance wheel 59 from moving down too quickly, causing the resistance wheel 59 to quickly slide off the second fitting plane 47 so that the follow-up impact component 4 is difficult to fall off from the massage component 2 and cannot be linked. On the other hand, the airbag can be compressed so that the airbag is inflated so that the gas penetrates into the gun housing 11, and the components in the gun housing 11 and the massage component 2 can be dissipated. On the other hand, the impurities in the gun housing 11 and the massage component 2 can be blown to loosen the impurities in the gap between the shaft cylinder 27 and the massage rod 29, so as to further promote the removal of impurities in the gap between the shaft cylinder 27 and the massage rod 29 by the follow-up impact component 4.

[0023] Next, the massage component 2 is given a more specific structure and construction as a whole for further explanation. The massage component 2 includes a built-in motor 21, which is detachably mounted in the gun housing 11. A first bevel gear 23 is detachably mounted on the output end of the built-in motor 21, a short shaft 24 is detachably mounted on the tail end of the output end of the built-in motor 21, and an eccentric wheel 25 is detachably mounted on the short shaft 24; a ball head seat 26 is detachably mounted on one side of the eccentric wheel 25, and a ball head groove is provided in the ball head seat 26; a built-in shell 22 is detachably mounted on the gun housing 11 In the built-in housing 22, a shaft cylinder 27 is detachably installed, a connecting seat 28 is slidably arranged in the shaft cylinder 27, a massage rod 29 is detachably installed on the connecting seat 28, and the massage rod 29 is located in the shaft cylinder 27, and the massage rod 29 can slide along the shaft cylinder 27; a connecting rod 291, a lower ball head 292 is detachably installed at its bottom end, and the lower ball head 292 is located in the ball head groove, and the lower ball head 292 can roll along the ball head groove, and an upper ball head 293 is detachably installed at the top of the connecting rod 291, and the upper ball head 293 is rotatably connected to the connecting seat 28; Next, the use principle of the massage component 2 as a whole is further explained. The user first turns on the switch of the built-in motor 21, so that the built-in motor 21 can drive the short shaft 24 and the eccentric wheel 25 to rotate as a whole. When the eccentric wheel 25 rotates as a whole, it can drive the ball head seat 26 to rotate as a whole. When the ball head seat 26 rotates as a whole, it can drive the connecting rod 291 and the massage rod 29 to move in the up and down directions as a whole, and then drive the massage connecting piece 3 to move in the up and down directions as a whole. The lower ball head 292 and the upper ball head 293 can rotate in the connecting seat 28. On the one hand, the eccentric wheel 25 can rotate as a whole due to the rotation. On the one hand, it can prevent the connecting rod 291 and the massage rod 29 from being suffocated due to excessive rotation, and on the other hand, the lower ball head 292 can be adaptively rolled while the eccentric wheel 25 is rotating, so as to reduce the kinetic energy loss when the connecting rod 291 and the ball head seat 26 are transmitted to each other. Compared with directly connecting the connecting rod 291 to the ball head seat 26 for rotation, the loss of the connecting rod 291 can be greatly reduced, and the life of the massage component 2 as a whole can be indirectly increased. In addition, the arrangement of the ball head groove can also have a benefit effect of facilitating the injection of wear-resistant oil or other lubricants into the gap between the lower ball head 292 and the ball head groove, so as to further reduce the kinetic energy loss when the connecting rod 291 and the ball head seat 26 are transmitted.

[0024] In some embodiments, more specifically, in order to further improve the smoothness of the massage rod 29 when it passes through the shaft tube 27, an airbag box 211 is detachably installed on the built-in motor 21, and the size of the airbag box 211 is adapted to the size of the built-in motor 21, and an airbag is removably arranged in the airbag box 211, and the size of the airbag is adapted to the size of the airbag box 211, and a nozzle 212 is detachably installed on the air outlet end of the airbag, and the nozzle 212 can pass through the airbag box 211, and there is also a socket on the airbag box 211, and the socket is located below the unlocking member 5.

[0025] In some embodiments, more specifically, in order to further improve the transmission performance between the ball head seat 26 and the connecting rod 291 and the massage rod 29, the diameter of the ball head groove of the ball head seat 26 is adapted to the diameter of the lower ball head 292, and the ball head groove of the ball head seat 26 can allow the connecting rod 291 to pass through, the length of the connecting rod 291 is smaller than the length of the massage rod 29, and the connecting rod 291 is located on one side of the eccentric wheel 25.

[0026] Next, a more specific structure and construction of the locking member of the follower striking member 4 is given for further explanation. The locking member of the follower striking member 4 includes a mounting seat 41, which is detachably mounted in the gun housing 11. A plug rod 42 is removably arranged in the mounting seat 41, and the plug rod 42 can slide in the mounting seat 41. The plug rod 42 can pass through the gun housing 11. A first spring 43 is removably sleeved on one end of the plug rod 42 located in the gun housing 11. A follower plate 45 is detachably mounted on one end of the gun housing 11, and has a first fitting plane 46 and a second fitting plane 47 on the follower plate 45. The first fitting plane 46 and the second fitting plane 47 form a step-shaped structure on the follower plate 45. The first spring 43 is located between the mounting seat 41 and the follower plate 45. A stopper 44 is detachably mounted on one end of the insertion rod 42 that passes through the gun housing 11, and the caliber of the stopper 44 is larger than the caliber of the insertion rod 42. Next, the use principle of the locking part of the follower impact component 4 is further explained. When the unlocking component 5 is in the highest position, the contact wheel 59 is in contact with the first fitting plane 46. During the contact between the contact wheel 59 and the first fitting plane 46, the first spring 43 is in a compressed state and a part of the insertion rod 42 is inserted out of the gun housing 11. Then, after the unlocking component 5 is operated to move downward as a whole, the contact wheel 59 can quickly slide off the first fitting plane 46. Since the first fitting plane 46 loses its obstruction, the first spring 43 can perform a short elastic reset, which can push the follower plate 45 to move a certain distance as a whole. At this time, the second fitting plane 47 also moves a certain distance synchronously. When the second fitting plane 47 and the contact wheel 59 contact each other, the follower plate 45 can be locked on the contact wheel 59 for a second time.

[0027] Next, the impact member of the follower impact member 4 is given a more specific structure and construction for further explanation. The impact member of the follower impact member 4 includes an impact base 48, which is detachably mounted on the follower plate 45, a striker rod 481 is removably arranged in the impact base 48, and the striker rod 481 can slide in the impact base 48, a first rebound seat 482 is detachably arranged on one end of the impact rod 481, and a first impact wheel 483 is rotatably arranged in the first rebound seat 482; a buffer shaft 484, which can slide The bottom guard ring 49 is detachably mounted on the impact base 48, a follower shaft 491 is rotatably mounted in the bottom guard ring 49, a cam 492 is detachably mounted on one end of the follower shaft 491, and the cam 492 and the first impact wheel 483 are in conflict with each other, and a second bevel gear 493 is detachably mounted on the other end of the follower shaft 491; Next, the use principle of the impact piece of the follower impact component 4 is further explained. After the follower plate 45 moves a certain distance as a whole, the impact base 48 can be synchronously displaced a certain distance. At this time, the second bevel gear 493 can be simultaneously displaced a certain distance so that the second bevel gear 493 and the first bevel gear 23 are meshed with each other. After the second bevel gear 493 is meshed with the first bevel gear 23, the output end of the built-in motor 21 can drive the first bevel gear 23 and the second bevel gear 493 to rotate when it rotates. After the second bevel gear 493 rotates, it can drive the cam 492 to rotate. After the cam 492 rotates, when the raised section of the cam 492 touches the first impact wheel 483, it can push the first impact wheel 483 to move backward to drive the second impact wheel 486 to move backward, so that The second impact wheel 486 impacts the gun housing 11. After the second impact wheel 486 impacts the gun housing 11, since the gun housing 11 is interconnected with the massage component 2, the impurities in the gun housing 11 and the massage component 2 can be loosened. On the one hand, it can effectively prevent the impurities from adhering to the inner wall of the gun housing 11. On the other hand, it can effectively prevent the impurities from staying in the gap between the shaft cylinder 27 and the massage rod 29, so that the smoothness of the massage rod 29 when it is extended from the shaft cylinder 27 is improved. On the other hand, by loosening the impurities in the gap between the massage rod 29 and the shaft cylinder 27, the resistance of the massage rod 29 to extend in the shaft cylinder 27 can be reduced, so as to further reduce the kinetic energy loss when the kinetic energy is transmitted between the ball head seat 26 and the connecting rod 291. In addition, the life of the massage rod 29 when used for a long time can be further extended.

[0028] In some embodiments, more specifically, a rod cavity is further provided in the impact rod 481, and the rod cavity can be penetrated by the buffer shaft 484, a second spring 4811 is detachably installed in the rod cavity, two groups of embedded blocks 4812 are detachably installed at the top of the impact rod 481 located in the rod cavity, an inner insert plate 4841 is detachably installed on one end of the buffer shaft 484 that penetrates into the rod cavity, and the inner insert plate 4841 and the second spring 4811 are in contact with each other when in the initial state; First of all, it should be explained that when the second impact wheel 486 is in the initial state, it is in conflict with the inner wall of the gun housing 11. At this time, the buffer shaft 484 is inserted deeper into the impact rod 481 and the second spring 4811 is in a compressed state. As the impact base 48 moves to the right, the second impact wheel 486 also moves to the right. Therefore, the second spring 4811 loses the limit of the unlocking member 5. Therefore, the second spring 4811 can push the second impact wheel 486 to move slightly to the left. On the one hand, it can effectively prevent the second impact wheel 486 from moving to the left. When moving right, the distance between the second impact wheel 486 and the inner wall of the gun case 11 is too large, which makes it impossible for the second impact wheel 486 to hit the inner wall of the gun case 11. This allows the second impact wheel 486 to always touch the inner wall of the gun case 11 when the first impact wheel 483 drives the second impact wheel 486 to move left. On the other hand, it can provide further buffering when the first impact wheel 483 drives the second impact wheel 486 to move left and touch the inner wall of the gun case 11, so as to prevent the second impact wheel 486 from touching the gun case 11 with too much force, causing the gun case 11 to shake violently as a whole.

[0029] Next, the unlocking member 5 is given a more specific structure and construction as a whole for further explanation. The unlocking member 5 includes an unlocking base 51, which is detachably mounted on the gun housing 11. An unlocking rod 52 is removably mounted in the unlocking base 51, and the unlocking rod 52 can slide up and down along the unlocking base 51. A plurality of countersunk holes 521 are provided on the unlocking rod 52, and a first pull ring 522 is integrally formed at the top of the unlocking rod 52; two groups of connecting plates 53 are detachably mounted on the two side surfaces of the unlocking base 51, and each group of connecting plates 53 is provided with a An external shaft seat 54 is detachably mounted, and the external shaft seat 54 and the connecting plate 53 are interconnected; a locking rod 55 is removably arranged in the external shaft seat 54, and a rebound plate 56 is detachably mounted on the locking rod 55; a third spring 57 is removably sleeved on the locking rod 55, and the third spring 57 is located between the connecting plate 53 and the rebound plate 56; a second pull ring 58 is detachably mounted on one end of the locking rod 55; a resisting wheel 59 is detachably mounted on the bottom of the unlocking rod 52, and the size of the resisting wheel 59 is adapted to the size of the unlocking rod 52; Next, the overall usage principle of the unlocking component 5 is further explained. When the unlocking component 5 is moved downward, the second pull rings 58 on the left and right sides are first pulled toward the left and right ends to allow the locking rods 55 on both sides to disengage from the countersunk holes 521. At this time, the rebound plate 56 can squeeze the third spring 57 for compression, and then push the first pull ring 522 to allow the unlocking rod 52 to move downward as a whole. After the unlocking component 5 can drive the follow-up impact component 4 to generate linkage with the massage component 2, the second pull ring 58 is pulled by Panasonic to allow the locking rod 55 to re-enter the countersunk hole 521 to complete the re-positioning of the unlocking rod 52.

[0030] In some embodiments, a conical plug is further provided at the other end of the locking rod 55, and a friction sleeve is detachably mounted on the conical plug, and the size of the friction sleeve matches the size of the conical plug, so that the locking rod 55 can be inserted into the counterbore 521; The conical plug and friction sleeve arranged on the locking rod 55 can, on the one hand, improve the stability of the locking rod 55 when it is inserted into the counterbore 521, and on the other hand, prevent the follow-up impact component 4 and the massage component 2 from falling off and becoming unable to link due to the shaking of the locking rod 55 when locking the unlocking rod 52.

[0031] In some embodiments, more specifically, a lower shifting rod 591 is detachably mounted at the bottom of the unlocking rod 52, the size of the lower shifting rod 591 matches the size of the unlocking rod 52, and the lower shifting rod 591 is located below the abutting wheel 59; The downward moving rod 591 is arranged so that it can penetrate into the airbag box 211 during the rapid downward movement of the downward moving rod 591 and squeeze the airbag in the airbag box 211. On the one hand, it can buffer the downward movement of the resistance wheel 59 to prevent the resistance wheel 59 from moving down too quickly, causing the resistance wheel 59 to quickly slide off the second fitting plane 47 so that the follow-up impact component 4 is difficult to fall off from the massage component 2 and cannot be linked. On the other hand, the airbag can be compressed so that the airbag is inflated so that the gas penetrates into the gun housing 11, and the components in the gun housing 11 and the massage component 2 can be dissipated. On the other hand, the impurities in the gun housing 11 and the massage component 2 can be blown to loosen the impurities in the gap between the shaft cylinder 27 and the massage rod 29, so as to further promote the removal of impurities in the gap between the shaft cylinder 27 and the massage rod 29 by the follow-up impact component 4.

[0032] Another technical problem to be solved by the present invention is a method for using a portable fascia gun. S1. Installing the massage connector 3: installing the massage connector 3 on the massage component 2 so that the massage component 2 can drive the massage connector 3 to move when it moves; S2, driving operation of the massage connecting member 3: opening the massage component 2 so that the massage component 2 can drive the massage connecting member 3 to move as a whole, and when the unlocking component 5 is located at the highest position in the initial state, the unlocking component 5 and the locking component conflict with each other, so that the follow-up impact component 4 is in a locked state; S3, placing the follower impact member 4 in a locked state: when the unlocking member 5 is at the highest position in the initial state, the unlocking member 5 and the locking piece are in conflict with each other, so that the follower impact member 4 is in a locked state; S4, moving the unlocking member 5 downward: operating the unlocking member 5 so that the unlocking member 5 can move downward along the direction of penetrating into the gun housing 11; S5, placing the follower impact member 4 in an unlocked state: when the unlocking member 5 moves downward, the unlocking member 5 and the locking member can be disengaged first and then contacted again, so that the follower impact member 4 is in an unlocked state, and when the follower impact member 4 is in the unlocked state, it can be linked with the massage member 2; S6. Linkage of the follower impact member 4: When the follower impact member 4 is in the unlocked state, after the massage member 2 is turned on, the follower impact member 4 can be driven to move at the same time to complete the impact operation on the entire gun housing 11.

[0033] 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.
