the driving ring body (51) is rotated, so that the driving plug (51 c) acts on the corresponding driven chute (52 d), and the telescopic lock cylinder (52) is driven to move downwards;
the locking inserting bar (52 c) moves downwards and is separated from the locking lower hole (41 a) and the rotating spiral ring (41), and the fixing device (4) is unlocked;
s2, primarily installing a sealing upper cover (3):
the lower connecting pipe (22) and the upper connecting pipe (23) are separated;
an inner rotating pipe (22) and a lower connecting pipe (21) are inserted into an outer threaded pipe (11), then a sealing upper cover (3) is sleeved on the external shell (1), a front stop ring (33) is sleeved on the lower connecting pipe (22) and positioned above a compression spring (26), the lower connecting pipe (22) is in sealing connection with the lower connecting pipe (22) through a first sealing ring, and then the lower connecting pipe (22) is fixed with an upper connecting pipe (23) again;
s3, primarily fixing the upper sealing cover (3):
rotating the spiral rotary ring (41) to rotate upwards;
the sliding lantern ring (42), the rotation stopping insertion block (42 a) and the trigger push rod (42 b) are driven to move upwards;
the trigger push rod (42 b) drives the torsion plate body (43 b) to rotate anticlockwise by overcoming the damping of the torsion spring (43 c), the other end of the torsion plate body (43 b) abuts against the inner stop block (32), the torsion plate body (43 b) continues to rotate anticlockwise, the inner stop block (32), the side cylinder (31) and the front stop ring (33) are driven to move downwards, and the second sealing ring is in sealing connection with the outer hexagonal pipe (16);
s4, locking, fixing and sealing the upper cover (3):
the driving ring body (51) is rotated, so that a driving plug (51 c) acts on the corresponding driven chute (52 d) to drive the telescopic lock cylinder (52) to move upwards;
the locking inserting bar (52 c) moves upwards and locks the locking lower hole (41 a) and the rotating spiral ring (41), so that the posture of the fixing device (4) is locked, and the locking and fixing of the sealing upper cover (3) are realized;
s5, automatic rotation water spraying:
the connecting spiral pipe (15) is connected with a water source and supplies water;
the water flow is ejected out after passing through the inner rotating pipe (21), the lower connecting pipe (22), the upper connecting pipe (23) and the eccentric bent pipe (24);
the jet flow generates a deflected counterforce to drive the rotating spray pipe (2) to rotate.
