2. The method for butt-jointing a pipe connection device for water supply and drainage engineering according to claim 1, characterized in that the butt-jointing method is as follows:
step one, a worker places two support plates (1) at the top ends of two water pipes to be connected, supports the two support plates (1) in an external fixing groove through two ends at the bottom of the two support plates, and inserts a first clamping ring (24) and a second clamping ring (27) at one end of the outer walls of the two water pipes respectively;
step two, through moving two first connecting rods (14) in opposite directions, the two first connecting rods (14) drive first racks (13) fixedly arranged at two ends of one side to slide along a first sliding groove and a first sliding bar (12), and the bottom ends of the four first racks (13) are respectively meshed with the top ends of the outer walls of the first gears (9) rotatably connected to one side of the first positioning block (2);
step three, four first gears (9) respectively drive two first screw rods (6) to rotate, so that second positioning blocks (7) which are in threaded connection with two ends of the outer wall of the first screw rods (6) drive clamping rings (10) at the bottom and anti-slip pads (11) to clamp one ends of the outer walls of two water pipes;
step four, the external rack is meshed with the top end of the outer wall of a second gear (17) fixed on the outer wall of a second screw rod (16) through the sliding of the external rack, so that the two second screw rods (16) rotate, one end of the outer wall of each second screw rod (16) is provided with two fixing blocks (15) in a threaded manner to drive one supporting plate (1) to move, and one end of one water pipe is abutted with one end of the other water pipe;
and fifthly, a second clamping ring (27) and a second positioning ring (29) which are inserted and arranged at one end of the outer wall of the water pipe at the other side drive a first positioning rod (30) which is fixedly arranged at two ends of one side to be inserted and arranged at two ends of one side of the first positioning ring (26) respectively, so that one ends of the two water pipes are mutually butted.
