Description

TECHNICAL FIELD

[0001] The utility model belongs to massager structure technical field, and specifically point to a massager. BACKGROUND

[0002] The massager is the necessity in people's daily life, and the most popular massager in the market is the fascia gun. The fascia gun, also known as deep muscle fascia impact instrument, is a soft tissue rehabilitation tool, which mainly relaxes the soft tissue of the body through high-frequency impact. The structure of the fascia gun is mainly composed of a main machine and a handle. The main machine is internally provided with a motor and other power components. At present, the common fascia gun adopts a crank connecting rod transmission structure and realizes the impact on the deep muscle fascia through the high-frequency vibration of the fascia gun and the extension and return movement of the massage ball.

[0003] For example, Chinese patent CN202410416984.5 discloses a simple integrated connecting rod self-adaptive transmission structure, which belongs to the technical field of fascia guns. It comprises a centering ball and a ball seat. The ball seat is in sliding cooperation with the centering ball. The inner cavity of the centering ball is in sliding cooperation with a fixing sleeve. The inner side of the fixing sleeve is integrally provided with a connecting rod. The end of the connecting rod away from the fixing sleeve is rotatably connected with an eccentric shaft. A bearing is arranged at the connecting position of the connecting rod and the eccentric shaft. The bearing is fixedly arranged at the inner end of the connecting rod. When the eccentric wheel drives the eccentric shaft to rotate by sleeving a centering ball on the fixing sleeve, the fixing sleeve can not only move forward and backward in the centering ball, but also enable the connecting rod and the fixing sleeve to swing left and right with the centering ball as the center and the eccentric radius of the eccentric shaft as the swing angle. When applied to the field of fascia guns, the massage ball can move forward and backward and swing left and right. This product takes into account the disadvantages of fascia guns, that is, only linear impact. Therefore, this product designs a fascia gun that can move forward and backward and swing left and right. This product has stronger adaptability, but also has some shortcomings. Both forward and backward movement and left and right swinging have their advantages, but this product cannot select forward and backward movement or left and right swinging. The basic way of this product is still hitting. There is a lack of massagers that can knock in the forward and backward direction and rub in the horizontal direction on the market. SUMMARY
