an annular sealing ring (m) is formed between the conical ring socket (17) and the conical plug (25).
6. The adjustable lawn sprinkler of claim 5, wherein:
the lower connecting pipe (22) and the upper connecting pipe (23) are detachably connected through buckles or threads.
7. A method of using a water jet device as defined in claim 6, wherein:
the method comprises the following steps:
s1, unlocking a fixing device (4):
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 cutting (52 c) descends and is separated from contact with the locking lower hole (41 a) and the rotary spiral ring (41), so that the posture of the fixing device (4) is unlocked;
s2, preliminarily installing a sealing upper cover (3):
separating the lower connecting pipe (22) from the upper connecting pipe (23);
inserting the inner rotating pipe (21) and the lower connecting pipe (22) into the external threaded pipe (11), sleeving the sealing upper cover (3) on the external shell (1), sleeving the front stop ring (33) on the lower connecting pipe (22) at the position above the compression spring (26), realizing sealing connection with the lower connecting pipe (22) through a first sealing ring, and then fixing the lower connecting pipe (22) with the upper connecting pipe (23) again;
s3, preliminarily fixing and sealing an upper cover (3):
rotating the rotating spiral ring (41) to enable the rotating spiral ring to rotate upwards;
the sliding lantern ring (42), the anti-rotation insert block (42 a) and the trigger push rod (42 b) are driven to ascend;
the trigger push rod (42 b) drives the torsion plate body (43 b) to rotate anticlockwise against the damping of the torsion spring (43 c), the other end of the torsion plate body (43 b) is abutted 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 connected with the outer hexagonal tube (16) in a sealing mode;
s4, locking and fixing the sealing upper cover (3):
rotating the driving ring body (51) to enable the driving plug (51 c) to act on the corresponding driven chute (52 d) to drive the telescopic lock cylinder (52) to ascend;
the locking cutting (52 c) moves upwards and locks the locking lower hole (41 a) and the rotary 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, automatically rotating and spraying water:
the connecting screw pipe (15) is connected with a water source and supplies water;
the water flow is ejected after passing through the inner rotary pipe (21), the lower connecting pipe (22), the upper connecting pipe (23) and the eccentric elbow pipe (24);
the jet flow generates a deflection reaction force to drive the rotary jet pipe (2) to rotate.
