The novel lifting hook safety clamp comprises a shell, a first pin shaft, a second pin shaft, an R-shaped spring, a tension spring and a baffle, the R-shaped spring is connected to the top end of the shell through a connecting pin, an L-shaped sliding groove is formed in the side wall of the shell, a through groove is formed in the bottom end of the shell, and the width of the through groove is larger than that of the hook end of a lifting hook; an upper mounting plate and a lower mounting plate which are arranged in parallel at intervals are fixed in the shell, the baffle is fixedly connected to the top end of the second pin shaft, the other end of the second pin shaft penetrates through the L-shaped sliding groove of the shell and is connected with the L-shaped sliding groove in a clamped mode, a through hole is formed in the center of the baffle, and the lower end of the first pin shaft sequentially penetrates through the upper mounting plate, the baffle and the lower mounting plate. The tension spring sleeves the outer surface of the first pin shaft, the upper end and the lower end of the tension spring are fixed to the upper mounting plate and the baffle respectively, when the second pin shaft is clamped to the shell, the tension spring is in a stretched state, and the lower end of the first pin shaft extends into the through groove and abuts against the lifting hook. According to the novel lifting hook safety clamp, the safety risk is reduced, and meanwhile, the working efficiency of replacing a lifting rope is improved.
