The invention provides a handle safety device which comprises a handle assembly, a support assembly and a safety pin, the safety pin is inserted into the handle assembly through the support assembly to be locked and pulled out to be unlocked, the handle assembly comprises a pull ring, a first shell, a trigger and a fork-shaped connector, one end of the first shell is fixedly connected with the pull ring, and the other end of the first shell is in the shape matched with the fork-shaped connector. The first shell can rotate around the shaft after the fork-shaped connector and the first shell are installed through the shaft, and opening parts are formed in the two sides of the first shell. The trigger is of a double-arm claw structure, one end of the trigger is an arm capable of being pressed, the other end of the trigger is a clamping claw, opening grooves are formed in the two ends of the fork-shaped connector, and the trigger is fixed to the opening portions of the two sides of the first shell, so that the clamping claw at one end of the trigger is located in the opening grooves to be upright and is moved away from the opening grooves to relieve constraint by pressing the other end. And the first shell fixedly connected with the handle assembly is driven to rotate to form constraint at the forward inclination position, so that the handle assembly is switched between the upright state and the forward inclination state.
