[0001] The invention relates to the technical field of fascia guns, in particular to a fascia gun. Background Art

[0002] The fascia gun, also known as the deep myofascial impactor, is a body soft tissue rehabilitation tool that relaxes the body's soft tissues through high-frequency impacts; it can also be used to treat soft tissue pain and relieve pain by relieving muscle tension. The fascia gun is also a tool that helps the body stretch and recover after exercise. It can be used by professional athletes and amateur bodybuilders. It mainly massages large muscle groups through high-frequency vibration massage, relaxes fascia, and reduces soreness, making exercise more effective.

[0003] The structure of the fascia gun of the prior art generally includes a fascia gun body, a driving part and a massage head. The driving part is installed on the fascia gun body and the driving end is connected to the massage head and drives the massage head to reciprocate. The driving part includes a motor and a reciprocating mechanism. The motor shaft of the motor is connected to the input end of the reciprocating mechanism to drive the reciprocating mechanism to move. The fascia gun of the prior art is generally set in an L shape to facilitate users to hold the fascia gun body, that is, the fascia gun body has a hand-held part, and a certain angle is set between the hand-held part and the fascia gun body. This causes the packaging volume occupied by the fascia gun to be larger, which increases the packaging cost and is inconvenient to carry and store. In addition, the massage head of the fascia gun of the prior art can only perform linear high-frequency reciprocating motion under the drive of the driving part, and its movement form is single, which cannot meet the user's needs for multiple massage methods. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned prior art and provide a fascia gun which has a small packaging volume, low packaging cost, is convenient to carry and store, and has various movement forms to meet the needs of users.

[0005] The technical solution of the present invention is to provide a fascia gun having the following structure:

[0006] A housing, wherein the housing comprises a first housing and a second housing, wherein a rotating mechanism is provided between the first housing and the second housing, and the rotating mechanism is used to rotate and switch the first housing and the second housing between a linear state and a vertical state;

[0007] A sliding seat, used for connecting the massage head, wherein the sliding seat is loosely fitted in the center hole of the first housing at an end away from the rotating mechanism;

[0008] The driving motor and the eccentric wheel assembly are both connected in the second housing, and the rotating shaft of the driving motor is drivingly connected with the eccentric wheel assembly to drive the eccentric wheel assembly to rotate;

[0009] A transmission rod assembly is disposed in the first housing, one end of the transmission rod assembly is connected to the sliding seat, and the other end of the transmission rod assembly is connected to the eccentric wheel assembly, for transmitting the torque of the driving motor;

[0010] When the first shell and the second shell are in a straight state, the eccentric wheel assembly drives the transmission rod assembly to move, so that the sliding seat rotates circumferentially in the center hole of the first shell; when the first shell and the second shell are in a vertical state, the eccentric wheel assembly drives the transmission rod assembly to move, so that the sliding seat reciprocates along the axial direction of the center hole of the first shell.

[0011] After adopting the above structure, the fascia gun of the present invention has the following advantages compared with the prior art: first, the shell of the fascia gun is composed of a first shell and a second shell, and the rotating mechanism arranged between the first shell and the second shell enables the first shell and the second shell to rotate and switch between a straight state and a vertical state. When the fascia gun is packaged or carried, the shell of the fascia gun can be rotated to a straight state, thereby reducing the packaging volume, saving packaging costs, and being easy to carry; secondly, when the first shell and the second shell are in a straight state, the eccentric wheel assembly drives the transmission rod assembly to move under the drive of the driving motor, so that the sliding seat rotates circumferentially in the center hole of the first shell, so that the massage head on the sliding seat performs a kneading massage, which can massage the head, back, waist, etc.; when the first shell and the second shell are in a straight state, the eccentric wheel assembly drives the transmission rod assembly under the drive of the driving motor, so that the sliding seat rotates circumferentially in the center hole of the first shell, so that the massage head on the sliding seat performs a kneading massage, which can massage the head, back, waist, etc. When the body and the second shell are in a vertical state, the eccentric wheel assembly drives the transmission rod assembly to move under the drive of the driving motor, so that the sliding seat reciprocates along the axial direction of the center hole of the first shell. At this time, the massage head on the sliding seat performs a high-frequency reciprocating hammering action, and the massage head can impact and relax the soft tissue of the body at a high frequency. Therefore, the massage head of the fascia gun has a variety of massage methods to meet the needs of different users; furthermore, the driving motor and the eccentric wheel assembly are both arranged in the second shell, and the transmission rod assembly and the massage head are arranged on the first shell.
