One end of the two guide rods 5 is connected to the upper side of the frame 2, and the other end is connected to the top of the machine base 1. Both sides of the lifting frame 4 are slidably connected to the two guide rods 5. The base 6 is installed on the top of the machine base 1. The two fixing components are connected to the top of the base 6. The tops of the two connecting seats 7 are inserted into the bottom of the lifting frame 4. Connecting bolts are arranged on both sides of the insertion part of the two connecting seats 7 and the bottom of the lifting frame 4. The two pressing tools 8 are installed at the bottoms of the two connecting seats 7;

[0023] Two fixing components, one of which includes: a support seat 9, a limit ring 10, four fixing seats 11, four springs 12 and four positioning rods 13;
