         3 . The device for quickly mounting and quickly detaching a faucet on the countertop according to  claim 2 , wherein: the receiving hole is a screw hole, when the step bolt is located in the first position, the thread section is at least partially located in the screw hole, the limiting section is located outside the screw hole, and the inner diameter of the screw hole is larger than the diameter of the thread section and the guide section; when the step bolt is located in the second position, the guide section is at least partially located in the screw hole. 
     
     
         4 . The device for quickly mounting and quickly detaching a faucet on the countertop according to  claim 3 , wherein: after the abutting piece abuts against the lower surface of the countertop, the step bolt is rotated so that the step bolt and the screw hole are locked, and the upper surface of the base and the countertop is tightened. 
     
     
         5 . The device for quickly mounting and quickly detaching a faucet on the countertop according to  claim 4 , wherein: the abutting piece includes a pressing plate and a cushion pad; the pressing plate is provided with a through hole which the thread section of the step bolt passes through the through hole and is connected with the pressing plate; the upper surface of the pressing plate is provided with a socket, and the cushion pad is provided with a corresponding plunger. 
     
     
         6 . The device for quickly mounting and quickly detaching a faucet on the countertop according to  claim 5 , wherein: the limiting piece is a limiting pin extending upward on the upper surface of the pressing plate. 
     
     
         7 . The device for quickly mounting and quickly detaching a faucet on the countertop according to  claim 6 , wherein: the limiting pin is arranged next to the through hole. 
     
     
         8 . The device for quickly mounting and quickly detaching a faucet on the countertop according to  claim 7 , wherein: the step bolts are two, which are symmetrically arranged along the axis of the hole; one end of each step bolt is provided with the pressing plate respectively. 
     
     
         9 . The device for quickly mounting and quickly detaching a faucet on the countertop according to  claim 8 , wherein: when the two step bolts are located in the first position, the pressing plates which connected to the two step bolts are in a state of stacking at different heights; the positions of the front end of the pressing plate and the cushion pad toward the limiting pin of the other pressing plate respectively are provided with a receiving groove. 
     
     
         10 . The device for quickly mounting and quickly detaching a faucet on the countertop according to  claim 9 , wherein: the elastic reset piece is a spring. 
     
     
         11 . The device for quickly mounting and quickly detaching a faucet on the countertop according to  claim 9 , wherein: the through hole is a threaded hole, and the step bolt is screwed with the pressing plate.
