A slider-type telescopic jaw mechanism

The invention discloses a slider-type telescopic jaw mechanism, which comprises a slider-type telescopic jaw and a resetting part for holding one end of the slider-type telescopic jaw to protrude outof an outer guide rail or an inner guide rail. The slider-type telescopic pawl mechanism is installed in a building climbing robot, the reset part of the slider-type telescopic jaw mechanism can keepthe slider-type telescopic pawl in a state that the slider-type telescopic pawl protrudes out of an outer guide rail or an inner guide rail, thereby facilitating the internal and external rails of thebuilding climbing machine to alternately climb on the building by means of an attachment wall seat installed on the building. The slider-type telescopic jaw mechanism is firmly contacted with the wall mount on the building in the climbing process of the building climbing machine, does not need precise alignment like the existing mechanical claw, and the mechanism has simple and effective workingmode, high working stability
