Parallel mechanical hand

The invention discloses a parallel mechanical hand. The parallel mechanical hand comprises a base, a motor, a connecting solenoid, a connecting screw, a mechanical hand base, a mechanical hand clamp and three connecting rod orientating mechanisms, wherein a motor installation hole is formed in the base, the motor is installed on the bottom of the base, an output shaft of the motor stretches upwards out of the motor installation hole to be connected with the lower end of the connecting solenoid, the lower end of the connecting screw is screwed and inserted in the upper end of the connecting solenoid, three mechanical hand connecting parts evenly stretch outwards from the mechanical hand base, the upper end of the connecting screw is fixedly connected with the bottom of the mechanical hand base, the mechanical hand clamp is installed on the top of the mechanical hand base, the upper end of each connecting rod orientating mechanism is connected with the corresponding mechanical hand connecting part in a rotary mode, and the lower end of each orientating mechanism is installed on the base. According to the parallel mechanical hand, the mechanical hand clamp can be prevented from deviating when the mechanical hand clamp moves up and down, and thus it is guaranteed that an article is conveyed to a position accurately by the mechanical hand.
