Special clamp for circular glass

The utility model relates to the technical field of glass, in particular to a special clamp for round glass, which comprises a disc, a plurality of baffles are uniformly arranged on the outer edge of one side of the disc, every two baffles are opposite, sliding rods are slidably connected in the baffles, and one end, far away from the disc, of each sliding rod is fixedly connected with an L-shaped fixing rod. The ends, away from the sliding rods, of the L-shaped fixing rods are fixedly connected with adjusting rods, the multiple adjusting rods are jointly meshed with the same gear, the multiple adjusting rods are opposite in pairs and located on the two sides of the two ends of the gear respectively, and the gear is rotationally connected with one side of the disc. Then the gear is rotated to drive the multiple adjusting rods to move in the direction close to the gear, then the multiple sliding rods are driven to move towards the circle center of the disc at the same time, one ends of the multiple sliding rod
