DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in this embodiment with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] like Figure 1-7 As shown, a fascia massage gun of the present invention includes a fascia massage gun housing 1, a massage head 2, and a power supply 3, a driving member 4, and an eccentric mechanism 5 located within the housing. The eccentric mechanism 5 is arranged in a linkage with the driving member 4. The eccentric mechanism 5 can also drive the massage head 2 to perform linear reciprocating motion via a transmission arm 6. A plurality of balls 7 are also installed in the fascia massage gun housing 1. The balls 7 are circumferentially abutted against the outer periphery of the transmission arm 6, and the transmission arm 6 slides on the inner side of the balls 7. The outer periphery of the transmission arm 6 is provided with a flat surface 6a that slides against the balls 7.

[0024] Specifically, at least three balls 7 are distributed circumferentially. The end of the transmission arm 6 has a transmission column 6b that reciprocates within the plurality of balls 7. The transmission column is fixed or integrally mounted on the transmission arm and can be a cylinder, square column, or triangular prism. Multiple flat surfaces 6a are distributed around the outer circumference of the transmission column.

[0025] Specifically, the massage head and the transmission column are plugged together via a plug-and-slot structure, which comprises a plug and a slot, wherein the slot is located on the transmission column and the massage head is mounted on the plug. The plug is pluggable and disposed in the slot.

[0026] Specifically, the fascia gun housing 1 has a main shell 11 and a head cover 12 located on the head of the main shell. There are multiple mounting grooves 111 on the circumference of the inner ring of the head of the main shell 11. A ball seat 8 is provided in each mounting groove 111. Each ball seat 8 is pressed against its own mounting groove 111 through a pressure platform 121 integrally provided on the inner ring of the head cover 12, and the ball 7 is installed on the concave cavity inside the ball seat 8.

[0027] Specifically, the driving member 4 is a motor, and the eccentric mechanism 5 includes an eccentric wheel 51. The eccentric wheel 51 has an axial hole 511 in the center for inserting the motor output shaft, and an eccentric shaft 512 off-center. The motor output shaft has a connecting hole 41 on the circumferential side. The eccentric wheel 51 also has a through hole 513 radially passing into the internal axial hole 511. After the eccentric wheel 51 is plugged into the motor output shaft, the through hole 513 is connected to the connecting hole 41 and is used for the connection of the connecting member. The connecting member can be a screw, a bolt, or a shaft. The transmission arm 6 has a connecting head 6c that is rotatably sleeved on the outside of the eccentric shaft 512, and a bearing 9 is also provided between the inner ring of the connecting head 6c and the eccentric shaft 512.

[0028] Specifically, the fascia gun housing 1 has a massage main body 1a and a handheld main body 1b. The massage main body 1a and the handheld main body 1b cooperate to form a "7" shape. The massage head 2 is located at the front end of the massage main body 1a. The "front" refers to the end of the massage head facing the human body when the fascia gun is in use. A control switch 10 and a charging interface are provided on the rear end face of the massage main body 1a. The power supply 3 and the transmission arm 6 are installed in the massage main body 1a, and the driving member 4 is installed in the handheld main body 1b.

[0029] In the present invention, the plurality of balls 7 are circumferentially pressed against the outer periphery of the transmission column 6a on the transmission arm, so that the transmission column 6a can reciprocate linearly inside the plurality of balls 7, thereby preventing the transmission arm 6 from deflecting. The balls 7 have a small contact surface with the transmission column 6a, which can reduce motion friction.
