[0002] The existing Chinese patent publication number (CN220011853U) includes a mold sleeve and a connector; the mold sleeve is annular, the inner wall of the mold sleeve forms a housing cavity for accommodating the mold, and the outer wall is provided with a trapezoidal groove with a large bottom and a small notch along the axis of the mold sleeve, and the trapezoidal groove extends from the front end to the rear end of the mold sleeve; the connector includes a connecting rod, a lifting ring and a protrusion, the lifting ring is integrally formed at the upper end of the connecting rod, and the protrusion is integrally formed at the lower end, and the protrusion includes a trapezoidal protrusion that only slides with the trapezoidal groove in the front and rear directions. The mold sleeve and the connector in this case are connected and matched by the trapezoidal groove and the trapezoidal protrusion to achieve a stable connection between the two. When assembling, it is only necessary to insert the trapezoidal protrusion into the trapezoidal groove from front to back, which is simple to operate, saves time and effort, and greatly improves the lifting efficiency; and compared with the threaded connection of the prior art, the connection between the protrusion and the groove is more stable and not easy to damage.

[0003] However, this requires providing a larger matching slide groove on the mold, which makes the mold design complicated.

[0004] This case is proposed to solve or improve the shortcomings or deficiencies of the prior art. Summary of the invention
