Description

Technical Field

[0001] This utility model relates to the field of massage device technology, specifically to a finger stretching massager based on a nested sliding structure. Background Technology

[0002] With the increasing demand for health care, finger massagers have gradually become a common product for relieving hand fatigue. Currently, most finger massagers on the market use a squeezing massage structure, which mainly achieves the massage effect by clamping or pressing, but lacks active stretching function for the finger joints.

[0003] Although some existing products are designed with finger stretching mechanisms, they generally use complex structures such as independent moving frames and limiting frames to achieve stretching movements, resulting in redundant internal components, high space occupancy, and increased risk of failure, affecting operational stability.

[0004] Patent document CN222488049U discloses a hand massage mechanism, including a movable frame, airbag finger sleeves, a driving device, and an inflation assembly. The airbag finger sleeves are worn on human fingers and can be inflated. The airbag finger sleeves are disposed on the movable frame. The driving device is connected to the movable frame and is used to drive the movable frame to move. The inflation assembly includes an air pump and multiple first air valves. The air pump is connected to each of the first air valves through pipes, and the multiple first air valves are respectively connected to each of the airbag finger sleeves through pipes, and are used to control the inflation and deflation of each airbag finger sleeve. Although this application can solve the technical problem of existing hand massage devices having only mechanical pressing techniques and a single massage method to a certain extent, it uses an additional movable frame and limiting frame to achieve active finger stretching, resulting in redundant internal components and high space occupancy.
