The invention discloses an anti-falling bolt mechanism. A bolt is connected to a mounting plate through a bolt fixing seat; a longitudinal sliding hole for the bolt to slide up and down is formed in the bolt fixing seat; the push rod is connected to the mounting plate through a sliding seat; the front part of the push rod is inserted into an assembly hole in the sliding seat and can slide back and forth along the assembly hole; a protruding edge protruding outwards in the radial direction is arranged on the rear portion of the push rod. One end of the compression spring abuts against the convex edge of the push rod, and the other end of the compression spring abuts against the end face of the sliding seat; the push plate is connected to the rear end of the push rod; an inclined long hole is formed in the push plate and composed of a first inclined hole and a second inclined hole which are smoothly connected. The inclination angle of the inclined hole I is smaller than that of the inclined hole II; a transvers
