Pivoted clamp for micro-runners

A pivoted clamp for micro-runners is used for clamping various smaller runners in narrow space. Two clamp claws and a clamp base are connected movably, a T-shaped piston is arranged in a cavity of the clamp base, two spherical surfaces of the piston contact with the two clamp claws, a supporting cap and a resetting spring are arranged between the two clamp claws, two clamp claw pivot points are formed by the supporting cap, the resetting spring is arranged in the piston and a supporting cap hole, an intake joint is mounted in a lower end hole of the clamp base, and a sealing ring is mounted on the piston in the cavity of the clamp base. When in use, pressure of air led into the clamp base pushes the piston so that the two spherical surfaces of the piston push the clamp claws to clamp and compress the supporting cap and the resetting spring between the two clamp claws. When air supply is stopped, the resetting spring resets so that the clamp claws are opened. The pivoted clamp for micro-runners is simple and c
