When the limit rod is retracted, it drives the mounting block to move upward at the same time. When moving, the two sets of transmission rods drive the two sets of fixed frames to rotate. The two sets of fixed frames drive the two sets of assembly frames and the two sets of fixed frames to move toward each other at the same time. When moving, the grabbing claws are driven to move toward each other synchronously, so that the workpiece body can be grabbed. When the operator grabs the workpiece body, the position of the workpiece body will not be displaced, and the problem of not being able to grab the workpiece body will not occur.

[0023] 2. When the grabbing is completed, the operator can control the hydraulic cylinder to recycle, and the hydraulic cylinder drives the toothed plate to recycle. When moving, the toothed plate drives the gear to rotate, and the gear drives the fixed rod to rotate, and the fixed rod drives the installation rod to rotate in the direction of the conveying mechanism.

When the mobile assembly rod drives the grab claw to move above the conveying roller, when the workpiece body contacts the conveying roller, the signal will be transmitted to the sensor at this time, and the sensor transmits the signal to the electric telescopic rod, and the electric telescopic rod drives the limit rod to extend. When the limit rod extends, it drives the installation block to move downward at the same time. When moving, the two sets of fixed frames are driven to rotate through the two sets of transmission rods, and the two sets of fixed frames drive the two sets of assembly frames and the two sets of fixed frames to move relative to each other at the same time. When moving, it drives the grab claw to move synchronously relative to each other, so that the workpiece body can be loosened and placed above the conveying roller for transportation. Then, when the operator grabs the workpiece body, the position of the workpiece body will not be displaced, so that the grabbing force can be controlled, the efficiency of feeding is improved, and it is convenient for the operator to use.

[0024] 3. By setting up anti-slip pads, the stability of the grasping claw in grasping the workpiece body can be improved to prevent the workpiece body from slipping.
