1. Equipped with touch keys and touch flywheel control for the device. 2. The device supports Bluetooth functionality, allowing control via mobile phones. 3. A large LCD display screen provides a clear view of all content on one screen. 4. Comes with a voice broadcast function for added convenience. 5. Enhanced real-time torque adjustment function that automatically stops when the torque exceeds the set range. 6. The limb rest uses double-sided support rods, ensuring smooth operation, simple, comfortable, and reliable limb fixation. 7. The range of joint motion and limb rest adjustment is extensive, meeting various clinical requirements. 8. The machine's operating speed can be continuously and smoothly adjusted to suit different stages of rehabilitation exercises. 9. An external emergency brake handle is provided for safety. 10. Equipped with an overload automatic stop safety feature (torque control), the machine stops automatically when abnormal resistance is encountered during operation, and the torque during movement can be set arbitrarily to ensure patient safety. 11. A universal hand controller is configured, allowing patients to control the machine's "extension," "flexion," and "start," "stop," which is convenient, practical, and enhances the sense of security for patients. 12. The power drive unit uses high-end domestic DC speed control motors with a lifespan of 10,000 hours. 13. The product structure is treated with galvanization, resulting in a smooth surface that is easy to clean. 14. Multiple position detection switches automatically correct and stop in case of an emergency. 15. With proper adjustment, it can be used for passive ankle joint exercises, achieving multi-functionality with one machine. Technical Parameters Technical Parameters: 1.
