Each of the finger mechanisms includes a plurality of finger sleeves and joint drivers. The sleeves of the finger mechanism are sequentially arranged at a distance and configured to be correspondingly worn on a plurality of knuckles of the user's fingers. Every two finger sleeves adjacent to each other of the finger mechanism are connected by one joint driver. The support plate and one of the finger sleeves closest to the support plate are connected by one joint driver. The joint driver is switched between a flat state and a curved state when the temperature of the joint drivers is higher than or lower than a phase change temperature value. A temperature control system is electrically connected to the respective joint drives and respectively controls the temperature of the joint drivers.
