[0026] Working principle: When loading and unloading workpieces, the mounting plate 1 is installed in the designated use area. Then, by starting the electric slide rail 3, the slide plate 4 is driven to move up and down by the electric slide rail 3, so as to achieve the effect of quickly moving the jaw 12 to one side of the workpiece for picking. Then, by starting the double-shaft cylinder 8, the output rod 9 is driven to expand and contract by the double-shaft cylinder 8, so as to drive the connecting plate 10 to move. Then, by the movement of the connecting plate 10, the mounting block 11 is further driven to move. Then, by the movement of the mounting block 11, the jaw 12 is further driven to open and close to clamp the workpiece. After the jaw 12 is used for a long time, the trapezoidal block 1501 can be separated from the inside of the jaw 12 by pulling the anti-slip pad 1502, so as to achieve the effect of facilitating the replacement of the old and worn anti-slip pad 1502.
