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: A modular gripper is disclosed and includes a main fixing plate, a driving module, two screw rods, two extension plates, two extension screws and two nuts. The two screw rods are arranged concentrically in the first direction, connected to the driving module, and driven by the driving module to rotate. The two extension plates are detachably docked to two sides of the main fixing plate through connection elements. The two extension screws are connected to the two screw rods, respectively. Threads of the two extension screws are continuously connected with threads of the two screw rods. The two nuts are sleeved on the two screw rods, respectively. When the two screw rods and the two extension screws are driven by the driving module to rotate synchronously, the two nuts are allowed to displace relative to the two screw rods and the two extension screws, to achieve a clamping operation.
