The invention discloses a hand stabilizing device. The hand stabilizing device comprises a glove body, a gyro device arranged on a hand back substrate of the glove body, a power accumulation device and a regulation device, wherein the gyro device is arranged on the hand back substrate of the glove body via a shell; the gyro device comprises a motor, a rotation shaft and a gyro rotor; the motor is fixedly connected with the top of the shell; the lower part of the motor is connected with the gyro rotor via the rotation shaft, so that the gyro rotor is close to the hand back substrate of the glove body; the motor is successively connected with the regulation device and the power accumulation device via a lead wire; the gyro device is controlled by the regulation device. The hand stabilizing device has the characteristics of small size, light weight, low cost and low power consumption; through adoption of the characteristic of the axis stability of the gyro rotor rotating at high speed, the high-speed motor drives the rotor to rotate at high speed; the generated angular momentum enables the gyro rotor and the whole glove to resist slight vibration, thereby remaining stable.
