Problems solved by technology

[0006] Although the above-mentioned massage drive mechanism and the massage gun correspond to the synchronous rotation state of the adjustment device relative to the eccentric drive device when the drive shaft is reversing, or are in a relatively static state, the output eccentricity of the eccentric drive device is changed to achieve positive and negative rotation. The vibration amplitude of the massage head; however, its structure takes up a lot of space and its stability is not good. The eccentric shaft needs a large enough fixing force, and the requirements for the material of the parts are high, otherwise it is prone to the risk of jamming or damage, and it is easy to get stuck when the motor is running at high speed. There are problems such as loud noise and severe jitter

Abstract

The invention belongs to the field of massage equipment, and particularly discloses a driving mechanism for a variable-amplitude fascia gun and with better structural stability and the variable-amplitude fascia gun comprising the driving mechanism. According to the driving mechanism provided by the invention, the eccentric distance of an eccentric shaft can be switched between e1 and e2, so the purpose that amplitude generated by a piston rod is A1 or A2 is achieved; and the driving mechanism adopts a bearing to tightly fit and install a rotating shaft, so loosening is basically avoided, high stability is achieved, and the noise and shaking generated during the high-speed operation of a motor are smaller. Besides, the driving mechanism is provided with fewer parts, the rotating shaft only rotates within the radian range of a rotary fixed arc groove, and the eccentric distance can be switched without moving back and forth, so the driving mechanism is compact in structure, small in occupied space, low in requirements on materials of the parts and favorable for saving cost.

Description

technical field [0001] The invention belongs to the field of massage equipment, and in particular relates to a variable-amplitude fascia gun and a driving mechanism thereof. Background technique [0002] The fascia gun, also known as the deep myofascial impactor, is a soft tissue massage tool that relaxes the soft tissue of the body through high-frequency impact. The existing fascia gun drives the massage head to do a reciprocating linear reciprocating motion through the massage drive mechanism. The massage head contacts the human body to generate high-frequency vibrations that affect the deep layers of the muscles, reducing local tissue tension, relieving pain, and promoting blood circulation. . [0003] Existing massage driving mechanism is mainly made of motor, the eccentric wheel that is arranged on the output end of motor, the transmission arm that one end is hinged with the eccentric shaft of eccentric wheel, and the piston rod that tail part is hinged with the other ...
