[0002] Treadmills are a common piece of fitness equipment in homes and gyms, and they are one of the simplest types of home fitness equipment available today. They are the best choice for home fitness equipment. Treadmill handrails help users maintain their body stability during exercise and prevent falls due to imbalance.

[0003] An existing electric treadmill with adjustable handrails (publication number: CN221815229U) can adjust the height of the handrails and rotate them horizontally through an adjustment mechanism. However, the adjustment is not flexible enough, and the user's grip range on the handrails is small. Due to different exercise habits of different users, the handrails cannot be used to maintain body stability more effectively when accelerating, decelerating, or performing certain special movements, making it inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable handrail height device for treadmills.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable handrail height device for a treadmill includes a treadmill body, a handrail support, and a lifting frame. The handrail support has a guide groove on its inner side, and the lifting frame is slidably connected to the guide groove.
