The slider 6 is slidably installed in the slide groove 10 of the lower template 2, and a square inclined hole 11 is provided in the middle of the slider 6 and runs through from top to bottom. A T-shaped slot 12 is provided at the front end of the slider 6, and positioning arms 13 are provided on both sides of the slider 6. The side core 7 is connected to the T-shaped slot 12 of the slider 6 through a T-shaped head 14 at the end, and an arc-shaped groove cavity 15 is provided at the other end of the side core 7. The push-pull rod 8 is provided with a square inclined rod pushing portion 16 adapted to the square inclined hole 11, a square straight rod positioning portion 17 is provided at the upper end of the square inclined rod pushing portion 16, and a conical rod positioning portion 18 is provided at the lower end of the square inclined rod pushing portion 16. The upper template 1 is provided with a square positioning groove 19 adapted to the square straight rod positioning portion 17 and a first screw 20 connected to the square straight rod positioning portion 17. After the square straight rod positioning portion 17 is inserted into the square positioning groove 19, it is fixed to the bottom of the upper template 1 by tightening the first screw 20.
