[0023] Specifically, the drive assembly 29 includes a second handle 291 rotatably mounted on one side of the fixed base 1. One end of the second handle 291 is fixedly connected to a second worm gear 292. A second worm wheel 293 that meshes with the second worm gear 292 is fixedly mounted in the middle of the first bidirectional screw 26. With the drive assembly 29, during operation, the second handle 291 can be manually rotated to drive the second worm gear 292 to rotate. The second worm gear 292 then drives the second worm wheel 293 to rotate, which in turn drives the first bidirectional screw 26 to rotate.

When dealing with mold steel of different sizes, the first handle 242 can be rotated to drive the first worm gear 243 to rotate, which in turn drives the first worm wheel 244 to rotate. The first worm wheel 244 drives the second bidirectional screw 241 to rotate, which in turn drives the two pressure plates 23 to slide along the slide groove 22. The position and spacing of the two pressure plates 23 on the same support base 21 can be adjusted, thereby facilitating effective fixing of the mold steel and improving practicality.
