Gear clamp

The utility model provides a gear clamp, which relates to the technical field of gear processing, and comprises a frame, which is rotatably connected with a longitudinally extending mounting shaft; the connecting rod transversely extends and is in sliding connection with two sliding blocks, and the connecting rod is provided with a pushing mechanism used for pushing the two sliding blocks to move towards each other or away from each other; and the number of the clamping arms is two, a U-shaped structure is defined by the two clamping arms, one ends of the two clamping arms are longitudinally and rotationally connected through a rotating shaft, the other ends of the two clamping arms are longitudinally and rotationally connected to the two sliding blocks respectively, arc-shaped extending racks are fixedly arranged on the inner walls of the two clamping arms, and the racks are made of flexible materials. The gear clamp solves the problem that in the prior art, a gear clamp is poor in universality. 本实用新型提供了一种齿轮
