[0011] Beneficial effects of the utility model:

[0012] The utility model adopts a symmetrical design of the clamping jaws to ensure the consistency of the center during the clamping process. The clamping jaws and the cylinder fingers are connected by positioning pins to ensure the installation accuracy. The clamping jaws adopt a slot-type (clamping slot) design to limit the upper and lower positions during the clamping process. The part of the clamping jaws that contacts the product adopts a sliding thread (sawtooth block) design, which does not affect the clamping of the product and increases the clamping force.
