Water and electricity construction slotting device and using method thereof

The invention discloses a grooving device for water and electricity construction and a using method thereof.The grooving device for water and electricity construction comprises a wall mounting part and a ground fixing part, during use, the wall mounting part is fixed through the ground fixing part, and due to the fact that workers need to stand on a base plate during construction, the wall mounting part is fixed through the ground fixing part; in this way, the stability of the base plate is guaranteed through the weight of a worker, the positioning rod is stabilized, then the propeller connected with the positioning rod exerts stable thrust, the fixing ring is stably fixed to the wall, the stability of the wall face installation part during construction is guaranteed, and then the wall face installation part can be installed through the installed wall face installation part. And the cutter is inserted into the gap between the connecting single body and the limiting rod and can only move along the gap, so that
