Specific embodiments

[0020] Such as Figures 1 to 7As shown in the figure, a high-strength ship fastening assembly includes a cylindrical main body mating connection seat 1. At the central positions of the upper and lower ends of the main body mating connection seat 1, there is an integrally formed cylindrical central assembly reinforcement column 2 respectively, which ensures better tightness at the central position during combination and higher structural strength. At the central position of the central assembly reinforcement column 2, there is a cylindrical central combination connection hole 3 that completely penetrates the whole in the up and down direction, and can cooperate with shaft-like components for penetration and combination. At the upper end of the main body mating connection seat 1, there are V-shaped limit mating connection grooves 5 that are evenly distributed in a circle and completely penetrate the outer side and the lower end of the whole, and can cooperate with the circumferential movable structure for limit mating during later use. At the same side position of adjacent limit mating connection grooves 5, there are first combination fastening grooves 6 and second combination fastening grooves 7 that are distributed in a staggered manner up and down, and can fasten and cooperate the structures combined on the upper and lower sides together in a staggered and embedded manner. At the inner included angle positions of the first combination fastening groove 6 and the second combination fastening groove 7, there are fastening combination avoidance grooves with a circular arc cross-section, which ensures better tightness during fitting, avoids the situation that the fitting at the included angle position is not in place easily, and solves the problem of poor tightness at the fitting position. On the first combination fastening groove 6 and the second combination fastening groove 7, there are cylindrical fastening combination connection holes 8 that completely penetrate the whole in the up and down direction, and cooperate with fastening bolts for fastening combination.
