It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the accompanying drawings are only used for exemplary illustration and cannot be understood as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0022] Refer to Figure 1-8 shown, which is a preferred embodiment provided by the present invention.

[0023] Refer to Figure 1 , the fascia gun massage head hardness adjustment mechanism includes a limiting groove 1, a slider 2, a slider connecting bolt 3 and an adjusting nut 4. The slider connecting bolt 3 passes through the limiting groove 1 and the slider 2. One end of the slider connecting bolt 3 is fixedly connected to the limiting groove 1 by a thread, and the other end is slidably connected to the slider 2. An elastic member 5 is provided between the limiting groove 1 and the slider 2, so the limiting groove 1 and the slider 2 are elastically connected. The adjusting nut 4 is arranged on the slider connecting bolt 3 to push the slider 2 to slide axially along the slider connecting bolt 3. This fascia gun massage head hardness adjustment mechanism is respectively connected to the fascia gun massage head and the fascia gun body. The adjusting nut 4 pushes the slider 2 to slide on the slider connecting bolt 3. The slider 2 compresses or relaxes the elastic member 5 to approach or move away from the limiting groove 1. Different compression distances between the slider 2 and the limiting groove 1 correspond to different massage head hardnesses.

[0024] Refer to Figure 1 , 4With respect to FIGS. 6 and 7, the elastic member 5 is preferably a spring. The two ends of the spring respectively abut against the limiting groove 1 and the slider 2. A spring is sleeved outside the slider connecting bolt 3, and the spring has a pre-tightening force when installed. One end of the slider connecting bolt 3 is inserted into the inner wall of the limiting groove 1 and fixed thereto by threads. The slider 2 includes an abutting end 21, a sliding cylinder 22, and an adjusting nut groove 23. The end of the slider connecting bolt 3 away from the limiting groove 1 penetrates through the abutting end 21, the sliding cylinder 22, and the adjusting nut groove 23. The abutting end 21 is used to abut against the spring, and the adjusting nut groove 23 is used to place the adjusting nut 4. At the same time, the adjusting nut 4 is movably connected to the slider connecting bolt 3 by threads. In order to prevent the adjusting nut 4 from slipping off the slider connecting bolt 3, the slider connecting bolt 3 is provided with a bolt head 31. By rotating the slider connecting bolt 3 or the adjusting nut 4, a relative displacement is generated between the slider connecting bolt 3 and the adjusting nut 4, so that the adjusting nut 4 pushes the slider 2 to slide, thereby changing the compression degree of the spring. The limit of the abutting end 21 of the slider 2 sliding towards the limiting groove 1 is that the abutting end 21 abuts against the limiting groove 1, and the two change from elastic connection to rigid connection. Therefore, the hardness adjustment range of the present invention is wide, meeting the hardness requirements of different users.

[0025] In a specific implementation, it is further optimized that the above-mentioned fascia gun massage head hardness adjustment mechanism is respectively integrated into the fascia gun massage head and the fascia gun body. The specific implementation scheme is as follows.

The limit groove 1 is fixed or clamped on the head 6 by threads. One end of the slider link bolt 3 is fixed in the limit groove 1 by threads. The massage head is detachably connected to the fascia gun body. Specifically, a buckle 24 is provided on the outer wall of the slider 2. The buckle 24 is a convex protrusion with a bar-shaped middle part and arc-shaped ends. A slot 71 matching the size of the buckle 24 is provided on the sleeve 7 of the fascia gun body. The slot 71 is a groove with an arc-shaped end, a bar-shaped middle part, and an open end for the buckle 24 to insert. A silicone sleeve 8 for sealing and fixing the two is also provided between the slider 2 and the sleeve 7. A hole matching the size of the buckle 24 is provided on the silicone sleeve 8. The silicone sleeve 8 is sleeved on the outside of the slider 2, and the buckle 24 passes through the hole of the silicone sleeve 8 and can be clamped with the slot 71. The massage head is clamped in the sleeve 7, and the sleeve 7 is fixed on the fascia gun body through a sleeve fixing seat 9. The sleeve 7 is connected to the transmission mechanism through a connecting rod, and the motor provides power for the transmission mechanism. Therefore, the sleeve 7 can drive the massage head to reciprocate. By rotating the head 6, the slider link bolt 3 is driven to rotate, so that a relative displacement is generated between the adjusting nut 4 and the slider link bolt 3. The adjusting nut 4 pushes the slider 2 to compress or relax the elastic component 5. Different compression degrees of the elastic component 5 correspond to different resilience of the massage head hitting the body, realizing the adjustment of the hardness of the massage head.

The limit groove 1 is fixedly connected to the slider link bolt 3. The limit groove 1 penetrates the sleeve 7 and is rotatably connected to the fascia gun connecting rod. The connecting rod is connected to a transmission mechanism, and the motor provides power for the transmission mechanism. Therefore, the connecting rod can drive the fascia gun massage head hardness adjustment mechanism to reciprocate. The massage head is detachably connected to the fascia gun body. Among them, the massage head includes a head 6 and a columnar body 10. The columnar body 10 is clamped on the slider 2. Specifically, a buckle 24 is provided on the outer wall of the columnar body 10, and a slot 71 matching the buckle 24 is provided on the slider 2. A silicone sleeve 8 for sealing and fixing is also provided between the slider 2 and the columnar body 10. The silicone sleeve 8 is sleeved on the outer wall of the columnar body 10. The sleeve 7 is fixed on the fascia gun body through a sleeve fixing seat 9.

[0030] Refer to Figure 7 , preferably, the slider 2 includes two cylinders with different diameters. The outer walls of the two cylinders are connected by an annular surface. A through groove with a convex-shaped longitudinal section is opened inside the slider 2. The elastic component 5 is sleeved on the outside of the cylinder with a smaller diameter and abuts against the annular surface. Spring pads are also provided between the elastic component 5 and the annular surface and the limit groove 1 respectively.

[0031] Refer to Figure 8 , inside the columnar body 10 there is an accommodation cavity, which is a channel 101 for the slider-linking bolt 3 to rotate forward. The inner wall size of the channel 101 near the slider-linking bolt 3 is adapted to the outer wall size of the adjusting nut 4, so that the end of the channel 101 near the slider-linking bolt 3 is stuck on the outer wall of the adjusting nut 4. The outer wall contour of the adjusting nut 4 is preferably triangular, polygonal, circular, etc. Further optimized, there is a groove for accommodating the bolt head 31 on the side of the adjusting nut 4 facing the bolt head 31.

[0032] Working principle: Rotate the massage head, the massage head drives the columnar body 10 to rotate, the columnar body 10 drives the adjusting nut 4 to rotate, and the slider-linking bolt 3 and the bolt head 31 advance and retreat in the channel 101. A relative displacement is generated between the adjusting nut 4 and the slider-linking bolt 3, pushing the slider 2 to compress or relax the elastic member 5. Different compression degrees of the elastic member 5 correspond to different resilience of the massage head hitting the body. The limit of the slider 2 sliding towards the limit groove 1 is that the slider 2 abuts against the limit groove 1, and the two change from elastic connection to rigid connection, with a wide hardness adjustment range to meet the hardness requirements of different users.
