This utility model discloses a mold opening and blank taking clamp arm for an extrusion blow molding machine, comprising a clamping arm body; a number of grooves are machined on the inner edge of the clamping arm body, and clamping teeth for clamping the excess material on the upper part of the blank are formed between every two adjacent grooves. An outwardly extending anti-adhesion fin plate is fixedly connected to the outer side of the clamping arm body. The excess material between the blank and the parison die head of the extruder can be clamped by the clamping teeth on the inner side of the clamping arm body, and the excess material expands into the grooves between the clamping teeth after being extruded, which can improve the clamping force of the clamping arm body; the clamped excess material is taken out together with the blank, realizing fast and convenient material taking and avoiding problems such as easy scalding caused by manual material taking. The outwardly extending anti-adhesion fin plate on the clamping arm body can prevent the excess material between the parison die head and the blank from collapsing onto the clamping arm body and causing adhesion during material taking, which is conducive to improving the operation efficiency.
