Description

Technical Field

[0001] The present invention belongs to the technical field of massage equipment, and in particular relates to a transmission mechanism with a split transverse elastic bracket, a fascia gun and a working method. Background Art

[0002] With the advancement of science and technology, people's living standards are constantly improving. More and more people are beginning to pursue the use of technological products to improve their health and relieve work pressure and physical fatigue. In addition to using masseurs and large and medium-sized massage equipment for massage, small and portable fascia guns have become the favorite of more and more people. The fascia gun, also known as the deep myofascial impactor, is a human soft tissue massage tool that relaxes the body's soft tissue through high-frequency impact. The fascia gun uses its internal special high-speed motor to drive the massage head, generating a high-frequency impact that reaches the deep muscle layer, achieving the effects of reducing local tissue tension, relieving pain, and promoting blood circulation. The traditional fascia gun transmission device is mostly an eccentric wheel driven by a motor, and the eccentric wheel drives the transmission rod to reciprocate. In order to limit the direction of the reciprocating motion of the transmission rod, a guide rod and a guide sleeve need to be set between the transmission rod and the fascia gun. In order to reduce movement resistance and noise, lubricating oil needs to be added between the guide rod and the guide sleeve. In actual practical applications, the amount of lubricating oil added is far from enough to meet long-term massage use. The fascia gun will increase power consumption and operating noise due to the lack of lubricating oil. Summary of the invention
