The two sets of L-shaped adjustment plates 3 extend away from each other on one side to the outside of the lower die 1 and are respectively connected to the U-shaped frame 4. The two sets of U-shaped frames 4 are connected to the lower die 1 through a linkage adjustment component. The top of the lower die 1 is provided with a plurality of evenly distributed positioning grooves 5. The bottom of the upper die 2 is provided with a positioning column 6 matching the positioning groove 5. The positioning column 6 is connected to the upper die 2 through a buffer component. The buffer component includes a pressure rod 18 provided at the bottom of the upper die 2. The bottom end of the pressure rod 18 extends into the positioning column 6 and is connected to the positioning column 6 through a buffer spring 19.
