A pressure type resistance controller for a lifting clothes horse
By using a worm gear transmission system driven by a dual-axis motor and a sensor torsion spring structure, the clothes rack can safely slow down and detect obstacles, solving the problem of collisions during the descent and improving safety.

AI Technical Summary
Existing clothes drying racks have motors that rotate at high speeds and are difficult to control, which makes them prone to colliding with people, furniture, or the ground during descent, resulting in poor safety.
The worm gear transmission system, driven by a dual-axis motor, achieves secondary speed reduction by combining multiple gears with different diameters. The motor is stopped by sensing the state of the suspended wire through sensors and torsion spring structure.
This effectively reduces the descent speed of the clothes rack, ensuring it stops promptly when encountering obstacles, thus improving its safety.
