[0025] In this embodiment, if Figure 2 As shown, the movable end of the driving device 20 is connected to the clamping rod 19 through the coupling 7, and the end of the slider body 1 is provided with a clamping groove 12 for clamping the clamping rod 19, which has a simple structure, convenient processing and convenient installation.

[0026] In this embodiment, if Figure 1 As shown, a mounting block 9 is connected to the bottom of the slider body 1, and friction blocks 4 are arranged side by side on both sides of the mounting block 9, with a simple structure.

[0027] In this embodiment, if Figure 4As shown, a notch 13 is provided on the upper portion of the slider body 1, and at least one sliding sleeve 16 is slidably provided on the side of the notch 13. A screw 17 is passed through the sliding sleeve 16, and the screw 17 is connected to the slider body 1. A spring 18 is sleeved on the screw 17, and the spring 18 abuts against the sliding sleeve 16. The auxiliary slider 2 can slide elastically through the sliding sleeve 16.

[0028] In this embodiment, if Figure 4 As shown, a first sliding hole 14 adapted to the sliding sleeve 16 is provided on the side of the notch 13 on the slider body 1 . The first sliding hole 14 and the sliding sleeve 16 are slidably matched, and the structure is stable.

[0029] In this embodiment, if Figure 6 As shown, a positioning protrusion 61 is provided at one end of the fixed block 6, a positioning groove 15 matching the positioning protrusion 61 is provided on the slider body 1, and a sliding groove 62 matching the auxiliary slider 2 is provided at the other end of the fixed block 6. The positioning is accurate, so that the fixed block 6 is faster and more convenient when connected to the slider body 1.

[0030] In this embodiment, if Figure 8 As shown, the mold base 10 is provided with a second sliding hole 101 matching the oblique pin 8, and has a simple structure.

[0031] In this embodiment, if Figure 1 As shown, the locking block 5 is fixedly set in the mold base 10, and the locking block 5 is used to limit the moving range of the slider body 1. The auxiliary slider 2 is then installed in the slide groove 62 of the fixed block 6, and the installed fixed block 6 is installed at the notch 13 of the slider body 1 by bolts. The slider body 1 is slidably set on one side of the locking block 5, and the movable end of the driving device 20 is connected to the clamping rod 19 through the coupling 7, and the clamping rod 19 is clamped in the clamping groove 12, and the oblique pin 8 is inserted into the auxiliary slider 2 and the second slide hole 101.
