Under the condition of no other external force, the first elastic piece can drive the clamping seat 122 to move towards the fixed seat 121, so that the workpiece 100 to be transmitted is clamped between the fixed seat 121 and the clamping seat 122, and the workpiece 100 to be transmitted is prevented from falling out of the material clamping groove 123;

the conveying seat 2 is used for providing motion guidance of the carrier 1 along the conveying direction, the carrier seat 11 is arranged on the conveying seat 2 in a sliding manner, and the conveying seat 2 at least has a feeding station along the conveying direction;
