[0005] Further, the front part of the holder is provided with two second threaded holes communicated with the containing cavity, and a side compression bolt is screwedly installed in the second threaded hole.

[0006] Further, the bottom of the holder is provided with four second process holes communicated with the containing cavity in a ring array around the first process hole.

[0007] Further, the base is provided with a longitudinal oblong hole at each corner.

[0008] Compared with the prior art, the eye mold mounting structure is changed to a screw lock nut and U-shaped lock block locking type structure, the holder and the gland are locked and fixed, after the screw and the lock nut are worn, only the two are removed and replaced, through the upper compression bolt compression positioning mode, the upper compression bolt does not need to be frequently rotated, the service life of the first threaded hole is prolonged, that is, the service life of the holder is prolonged, five process holes are arranged at the bottom of the holder, and the problem that the eye mold body is tilted and stuck when the single center process hole is ejected is avoided.
