The invention mainly saves the underground trapped personnel by automatically tightening the mesh bag structure; specifically, stranded personnel body trunk part is in accommodation space 36, and the lower support body passes from stranded personnel armpit, and when the personnel of suing and labouring above the well head carried the suspender, the suspender tightened up, and correspondingly, the triangle district space was drawn down with the accommodation space, can "tie up" stranded personnel, and at this moment, only need continue to lift, can rescue out stranded personnel.

The mesh bag structure has self-adaptive characteristics, and can be well adapted even if the body shape or the weight is different (namely, the sling can be adjusted in an up-down, left-right adaptive telescopic manner). For example, if a child is rescued, it will contract less, and if it is a rescued adult, it will expand somewhat adaptively. After the life saving device is placed underground, the trapped person can be lifted and saved without the cooperation of the trapped person.

As shown in fig. 6, the structure between the upper rod body and the base body may be specifically: a cavity 37 is formed in the base body, a handle part 38 is arranged at the tail end of the lower base body (on the lower base body), the handle part extends into the cavity of the base body, the lower base body is hinged to the base body, a mounting seat 39 is arranged at the position close to the opening of the cavity of the base body, the upper rod body penetrates through the base body and is screwed on the mounting seat in a threaded mode, the lower rod body corresponds to the handle part, and when the upper rod body abuts against the handle part to move downwards, the lower base body can rotate at a hinged point between the lower base body and the base body.
