[0008] As an improvement of the utility model, the cross section of the protrusion and the guide groove is rectangular.

[0009] As an improvement of the utility model, the rear end of the elastic positioning pin is provided with a spring.

[0010] As an improvement of the utility model, the sealing ring is an elastic rubber ring.

[0011] The outermost end of the guide groove is a guide opening, and the outer diameter is larger than the inner diameter.

[0012] The utility model discloses the beneficial effects are:

[0013] (1) the outer side of pipe body inserts into guide groove through a plurality of convex blocks, and cooperation is accurate, and the outermost end of guide groove is horn mouth, and it is convenient to connect.

[0014] (2) after the convex block inserts into the guide groove set position, the elastic positioning pin pops up and presses against the positioning blind hole, so that the front and rear two top pipes will not be loose after being connected.

[0015] (3) the middle part of connecting ring is equipped with sealing ring, and after the front and rear two top pipes are connected, the sealing ring is pressed in the recess of end face, can buffer the impact force when connecting, also plays the role of leakage prevention.

[0016] (4) the connecting ring is externally equipped, further improves the sealing property of connecting place, and reduces the possibility of underground water seepage into top pipe. BRIEF DESCRIPTION OF DRAWINGS
