This utility model relates to a hand rehabilitation training tool for hemiplegic patients, including a lower palm support plate and a lifting adjustment component. The lifting adjustment component includes a lifting tube connected to the lower palm support plate and a lifting rod slidably connected to the lifting tube. An upper palm support plate is connected to the lifting rod. The technical solution of this application has the following advantages: the lower palm support plate is connected to the lifting tube, the lifting rod is slidably connected to the lifting tube, and the upper palm support plate is slidably connected to the lifting rod, thereby facilitating the adjustment of the upper and lower palm support plates. This solves the problem that existing hand support devices, such as fixed brackets and rehabilitation training trays, are mostly fixed structures, which cannot adapt to the differences in hand size and finger length among different users, resulting in inaccurate support position and affecting the effectiveness of use.
