Electric support

The invention discloses an electric support which comprises a base, a motor is arranged on the base, an output end wheel of the motor is meshed with an intermediate gear, and the intermediate gear ismeshed with a transmission wheel. A stand column is arranged on the end face of the transmission wheel and embedded into the long groove of a sliding block. The sliding block slides along a first guide rail, and the first guide rail is fixed on the base. A top plate is arranged on the upper portion of the sliding block. A workpiece is placed on the top plate. A second guide rail is arranged at thetop end of the base, and the top plate slides in the second guide rail. The electric support has the advantages that the support is driven by the motor, and the motor can be a stepping motor, so thatthe ascending height of the sliding block can be accurately controlled, and the distance between a lower workpiece and the output end of the motor is further controlled. 本发明公开种电动支架，包括基座，所述基座上设置电机，电机输出端轮与中间齿轮啮合，中间齿轮与传动轮啮合；所述传动轮
