Among them, the mechanical arm in the machine has strong flexibility. However, the clamping surface of an existing mechanical arm is a flat surface, which is not suitable for clamping and processing workpieces with irregular shapes, reducing the clamping effect of the mechanical arm, and may cause the workpiece to loosen when moving or processing the workpiece.

[0003] For example, a multifunctional mechanical arm with announcement number CN221021061U includes a column, a lifting mechanism and a clamping mechanism, wherein the inner wall of the column is provided with a sliding hole; the lifting mechanism includes a first motor, a screw, a lifting ring and a cross bar, wherein the output end of the first motor is fixedly connected with a screw, the outer side of the screw is threadedly connected with a lifting ring, the outer side of the lifting ring is fixedly connected with a cross bar, and the outer side of the cross bar is slidably connected with the inner wall of the sliding hole; the clamping mechanism includes a cylinder, a lifting block, a rotating shaft, a limit block, a pull rod, a movable plate and a clamping plate, wherein the cylinder piston rod is fixedly connected with the lifting block, which solves the problem that the existing multifunctional mechanical arm has a relatively single clamping range when clamping objects, and cannot adjust the width according to the size of the objects, resulting in a limited application range of the mechanical arm and reduced work efficiency.
