The two gripping arms are pivotally connected to the support base, one of the gripping arms has a pushed portion, and a plurality of driving teeth are formed on each gripping arm. The driving teeth of the two gripping arms are engaged with each other. When the telescopic rod of the driving mechanism is extended, it can drive the pivot mechanism to swing. The pivot mechanism drives one of the gripping arms to swing away from the other gripping arm, and the two reset components are respectively arranged between the two gripping arms and the support base to push each gripping arm to reset.

[0003] However, the above-mentioned method requires resetting the clamping arms through a reset member, and the reset member is prone to elastic fatigue after long-term use, resulting in inaccurate clamping action, which in turn causes the opening and closing angles of the two clamping arms of each clamping jaw moving unit to be inconsistent, thereby affecting the accuracy of the blow molding machine operation.
