Hot air ice and snow removing length adjusting device

The invention relates to the technical field of cable snow removing equipment, in particular to a hot air ice and snow removing length adjusting device, through a sliding rod, a first water absorption sponge and a pressing column, in the ice removing process, water generated after ice and snow are melted flows in the length direction of the sliding rod, firstly makes contact with the first sponge and is adsorbed in the first sponge, and the first water absorption sponge is pressed into the pressing column; when a pressing column rotates, a first sponge is extruded, water is pressed into a first communication channel in a fixed cylinder and is blow-dried and discharged along the first communication channel, and when part of the water flows along the outer side of the fixed cylinder through a third water absorption sponge, the water is discharged out of the fixed cylinder. And a third water absorption sponge adsorbs the cable snow and dries the cable snow along with a spiral hot air duct in a first communicatio
