[0018] The six latch teeth 4 are evenly distributed in a ring shape inside the plug opening, and the bottom cover 1 is made of a polyurethane composite material.

[0019] The specific implementation method is as follows: when the utility model is used, since the latch teeth 4 are tilted upward and evenly distributed in a ring shape inside the plug mouth, the problem of explosion refusal caused by the detonator falling off can be effectively prevented. A conical cylindrical anti-falling plug 5 is arranged on the top of the latch teeth 4, and its bottom is tightly fitted with the core mold to ensure that there is no leakage of medicine during the pouring and cooling process, reduce the production leakage waste rate, simplify the production process of the bottom cover 1, reduce the human factors and management factors in the production process, realize process quantification, and solve the problems of medicine leakage blocking the functional hole during pouring, poor rebound of the latch teeth 4 after high temperature, and insufficient detonator tension. The problem is that the limiting column 2 can effectively fix the position of the explosive package, accurately match the detonator energy, and stably concentrate the energy in the center of the explosive package without displacement. The maximum energy matching position can be found through experiments, thereby enhancing the explosive power of the detonator, and is more conducive to the release of explosive energy in the blast hole.
