On the basis of the above structure, a safety hook 221 is arranged at the top of the speed limiter 22, and the safety hook 221 is hung on the fixing piece 24.
In the process of using the slow-descent device, as the slow-descent rope 23 needs to pass through the speed limiter 22, the speed limiter 22 is a main bearing structure when the speed limiter 22 falls down as a human body, and the speed limiter 22 is directly hung on the fixing piece 24, so that the speed limiter 22 directly bears the weight through the fixing piece 24 fixed on the wall body, the slow-descent device is prevented from falling down, and the user is ensured to stably and slowly fall down.
Further, the safety hook 221 is provided with a locking member 222, the locking member 222 is located at an opening of the safety hook 221, one end of the locking member 222 is hinged to one side of the opening of the safety hook 221, and the other end of the locking member 222 abuts against the other side of the opening of the safety hook 221.
When the descent control device is installed, the speed limiter 22 is hung on the fixing member 24 from one side of the fixing member 24 through the locking member 222, and in order to avoid the detachment of the hook, the opening part of the locking member 222 is sealed through the safety hook 221, so that stable hanging is realized.
And, the end of the fixing member 24 far from the wall body is provided with a safety post 241. The width of the safety post 241 is larger than the closed through hole between the locking piece 222 and the safety hook 221, so as to further avoid the speed limiter 22 from falling off and ensure the stable hanging of the speed limiter 22.
