Self-adaptive mechanical clamping jaw with self-locking function

The utility model relates to the technical field of cream bottle shaking machines, in particular to a self-adaptive mechanical clamping jaw with a self-locking function, which comprises a base, a self-locking slide block and a connecting rod, one end of the self-locking sliding block is installed in the base in a sliding mode, and a self-locking assembly is installed at the position, making contact with the self-locking sliding block, in the base. The number of the connecting rods is two, one ends of the two connecting rods are rotationally connected and installed on the self-locking sliding block, the inward sides of the two connecting rods are each provided with an elastic rubber ball, and the number of the elastic rubber balls is four. According to the self-adaptive mechanical clamping jaw with the self-locking function, the use convenience and the use frequency of an operator are fully considered; a connecting rod mechanism and a self-locking button are combined with a spring and a rubber ball to store en
