背景技术
筋膜枪是人们运动后使用的一种进行肌肉放松的按摩设备，其结构通常包括横向的壳体和纵向的手柄，在壳体的前端设有可以往复震动的按摩头。使用时，将按摩头压在肌肉处震动肌肉，通过其精准、高频、深度的震动，来冲开肌肉粘连，让肌肉发热，活跃细胞，使血液流通更顺畅，从而加快肌肉恢复，降低乳酸，达到舒筋活血的效果。
现有的筋膜枪结构如专利公开号CN110179646A所示，它采用了传统往复锯的传动结构，包括了连接在偏心轮上的电机，与偏心轮铰接的曲柄接合轴承保持器，曲柄接合轴承保持器前端铰接活塞，活塞限制在壳体上，并设有按摩头与活塞连接，现有的传动结构复杂，需要借助柔性传递装置能够弯曲而不折断的性能，通过摆动将旋转运动转换成直线往复运动，这不仅会带来生产成本的增加，也会因为柔性传递装置的不稳定性对筋膜枪的性能和使用寿命造成影响。
