The above patent uses a locking block structure to achieve the function of clamping the casting during stretching. However, since the two sets of locking blocks that clamp the casting are arranged vertically, people need to hold the casting for clamping. Not only is it inconvenient to clamp the casting, but people also have the risk of getting their hands pinched. Therefore, in order to advance the industry technology, better realize the clamping and fixing function of the casting during stretching, and improve the competitiveness of core technologies, this application proposes a new implementation scheme that is different from the prior art method of clamping and fixing the casting before stretching.

[0007] Furthermore, the clamping assembly includes a support seat, an inner wall of one end of the support seat is fixedly connected to a second electric push rod, and one end of the second electric push rod is fixedly connected to a movable clamping plate.
