[0002] With the continuous development of society, people's living standards are constantly improving. Therefore, when people are tired, they will use fascia guns to relieve fatigue and achieve the effect of massage relaxation. The fascia gun, also known as the deep myofascial impactor, is a soft tissue rehabilitation tool that relaxes the body's soft tissue through high-frequency impact.

[0003] In the prior art, CN 220125076U discloses "a four-head fascia gun that is easy to grasp", including a housing; a driving source, which is installed inside the housing, and the driving source has two output ends; a motion assembly, which has two, and the motion assembly includes an eccentric wheel, a first swing rod and two swing mechanisms, the first swing rod is connected to the output end of the driving source through the eccentric wheel, and the two swing mechanisms are respectively connected to the two ends of the first swing rod and extend out of the housing, and at least parts of the two swing mechanisms are hinged; a massage ball is sleeved on the swing mechanism. Based on the above, the inventor found that: in the comparative document, since its driving source is a double-head drive motor, the driving form is relatively complicated, which may result in high production costs of the fascia gun, fast power consumption when starting up, and there are fewer places for the external hand to grasp, which may be inconvenient for users to grasp and control it when using it. Therefore, in view of this, the existing structure is studied and improved to provide a four-head fascia gun that is easy to grasp, in order to achieve a more practical purpose.

[0040] See also Figure 1-5 A four-head fascia gun that is easy to grasp comprises a lower shell, an upper shell 2 is fixedly mounted on the top of the lower shell 1, a motor 4 is fixedly mounted inside the lower shell 1, an output end of the motor 4 is connected to an eccentric wheel 5 through a coupling transmission, a swing rod 6 is sleeved on one end of the eccentric wheel 5, a pair of swing rods 7 are respectively mounted on one end of two support rods of the swing rod 6 through the eccentric rod, connecting blocks 8 are mounted on both ends of the pair of swing rods 7 through a rotating shaft, and a reciprocating column 9 is mounted on one end of each connecting block 8 through a rotating shaft, a massage ball 10 is arranged on one end of the reciprocating column 9, and the motor 4 in the device can effectively drive the four massage balls 10 to perform reciprocating vibration massage up and down, thereby reducing the complexity of the structure and the manufacturing cost.

[0041] See also Figure 1 , 3 The outer walls of the lower shell 1 and the upper shell 2 are each provided with a pair of grip grooves 3, and the positions of each pair of grip grooves 3 are symmetrical to each other. The grip grooves 3 can effectively facilitate the user to hold the device for massage; the two support rods of the swing rod 1 6 are symmetrical to each other, and both support rods are "L"-shaped; a pair of swing rods 2 7 are respectively located on both sides of the motor 4, and the positions of the pair of swing rods 2 7 are symmetrical to each other. By setting the position of the swing rod 2 7, the balance of the four massage balls 10 when moving up and down can be effectively ensured.

[0042] See also Figure 3 , 4 A pair of rocker arms 7 are connected to the inner wall of the lower shell 1 through a rotating shaft, and the rotating shaft is located in the middle position of the outer wall of the rocker arm 7. The rocker arm 7 is connected to the inside of the lower shell 1 through the rotating shaft, so that the amplitude of the reciprocating column 9 driven by the two ends of the rocker arm 7 to swing up and down is more uniform; one end of the four reciprocating columns 9 passes through the outer side of the lower shell 1 through a through groove, and the positions of the four reciprocating columns 9 are symmetrical to each other; a silicone sleeve 11 is sleeved and installed on the outer side of the four reciprocating columns 9, and the outer wall of each silicone sleeve 11 is fixedly connected to the inner wall of the lower shell 1. The silicone sleeve 11 can effectively prevent the reciprocating column 9 from excessive displacement when moving up and down.

[0043] See also Figure 4 One end of the reciprocating column 9 is fixedly connected to the massage ball 10, and the massage ball 10 is wrapped around the outer wall of one end of the reciprocating column 9. By wrapping the massage ball 10 around one end of the outer wall of the reciprocating column 9, the vibration feeling of the massage ball 10 driven by the reciprocating column 9 can be effectively improved.

[0044] When in use: first, the user inserts his hand into the grip groove 3, holds the lower shell 1 and the upper shell 2 in his hand or grasps the two sides of the device with both hands, and then drives the eccentric wheel 5 to rotate through the motor 4. At the same time, the eccentric wheel 5 will drive the two ends of the pendulum rod 1 6 to move up and down. The pendulum rod 1 6 can drive one end of the pendulum rod 2 7 to move up and down, and the reciprocating column 9 can be driven to move up and down through the connecting block 8, so that the massage ball 10 can vibrate and massage the user's limbs.
