[Claims for Utility Model Registration] 1. An arm body; a fixed gripper fixed to the tip of the arm body and forming an arcuate tool grip; and a fixed gripper located opposite to the fixed gripper; a swinging gripper that is swingably supported to open and close and forms an arcuate tool grip; a spring mechanism that biases the rear end of the swinging gripper in a direction in which the gripper closes; the spring mechanism an automatic tool changer comprising: a hydraulic device that supplies pressure oil to maintain the spring biased state; and a swing gripper locking mechanism that presses and fixes the swing gripper in a direction perpendicular to its swing surface. Equipment tool changing arm. 2. The spring mechanism includes a first piston rod that is slidably disposed in a cylinder portion formed in the arm body and has a notch into which the rear end of the swing gripper is inserted and engaged; a spring that contacts and urges the piston rod in a direction in which the swing gripper closes; The tool changing arm according to claim 1, which is a registered utility model, and further comprises: a second piston rod that abuts on the opposite side of the first piston rod; 3. The tool according to claim 2, wherein the hydraulic device has a hydraulic circuit that supplies pressure oil to a side of the second piston rod opposite to the side that is in contact with the spring. Replacement arm. 4. The locking mechanism is characterized in that it includes a pressing member that contacts the swinging gripper from a direction perpendicular to the swinging surface thereof; and a spring that biases the pressing member toward the swinging gripper. A tool changing arm according to claim 1 of the utility model registration claim. 5. The tool changing arm according to claim 4, wherein a tapered surface is formed at the contact portion of the pressing member and the swinging gripper with which the pressing member comes into contact. 6.
