[0002] Coal mines are areas containing coal resources that are mined by humans. Generally, if the coal resources are far away from the ground, underground mining construction will be used for the corresponding mining work. However, in the actual process of underground mining, the safety requirements of the entire mine will be very high. Since various safety accidents may occur underground, a lot of corresponding underground safety escape devices are needed, such as underground escape devices.

The connecting slide cylinder is fixedly mounted on the upper end of the breathing mask, and the positioning rod is slidably mounted on the inner end of the connecting slide cylinder. The positioning block is fixedly mounted on the upper end of the positioning rod. The positioning screw is movably connected to the inner end of the positioning block. An electric push rod is provided between the positioning rod and the connecting slide cylinder, a linkage seat is provided at the lower end of the electric push rod, a clamping block is provided at the lower end of the linkage seat, an outer through hole and an inner through hole are provided at the outer end of the clamping block, and a slide groove is provided at the outer end of the electric push rod.
