Abstract: A gripper structure is disclosed and includes a screw-rod main body, a first rotatory nut, a second rotatory nut, a first driving module, a second driving module, a first clamping element and a second clamping element. The first rotatory nut and the second rotatory nut are disposed on two sides of the screw-rod main extended along a first direction body, respectively, and bilaterally symmetrical to each other. The first driving module and the second driving module are configured to drive the first rotatory nut and the second rotatory nut to rotate, respectively. The first rotatory nut and the second rotatory nut are allowed to pass through a midline of the screw-rod main body. When the first driving module drives the first rotatory nut or/and the second driving module drives the second rotatory nut, the first clamping element and the second clamping element are relatively displaced in the first direction to achieve a clamping operation.

Abstract: An electric gripper is disclosed and includes a carrier, an actuator, two dual-lever assemblies and an angle sensor. The actuator is disposed on the carrier and includes a sliding portion. The two dual-lever assemblies are disposed on the carrier and located at two opposite lateral sides of the sliding portion. Each of the two dual-lever assemblies includes a driving lever, a limiting lever and a gripping piece. The driving levers are staggered to each other. The limiting levers are staggered to each other. When the sliding portion slides a first distance in the first direction, the sliding portion drives the driving levers to rotate an angle, and the gripping pieces move toward each other to displace a second distance in a second direction. The angle sensor is disposed on the carrier and configured to measure the angle, to correspond to the first distance and the second distance.
