The positioning assembly is used to limit the relative rotation between the lower pipe pile 1 and the upper pipe pile 2. The automatic connecting assembly includes a connecting ring 23, which is fixedly connected to the bottom end of the upper connecting seat 21, and the connecting ring 23 is inserted inside the first connecting groove 24. The first connecting groove 24 is provided at the top of the lower connecting seat 22, and notches 25 are provided at both the front and rear ends of the connecting ring 23. An active rack 26 is fixedly connected to the inner wall of the notch 25. The active rack 26 is meshed with a transmission gear 27. The transmission gear 27 is rotatably connected to the inside of a transmission cavity 28. The transmission cavity 28 is provided inside the lower connecting seat 22 and the transmission cavity 28 is connected to the first connecting groove 24 and the storage cavity 30. The storage cavity 30 is provided at the top of the lower connecting seat 22. The transmission gear 27 is also meshed with a passive rack 29. The top of the passive rack 29 is inserted in the connecting seat 22.

When the passive rack 29 is inserted into the connecting cavity 31, the inner wall of the connecting cavity 31 squeezes the inclined surface provided on the connecting block 34, so that the connecting block 34 is pressed under the action of the squeezing force. The connecting ring 23 moves downward into the interior of the active cavity 32 and squeezes the first spring 33, causing the first spring 33 to produce elastic deformation under the action of the squeezing force. When the connecting ring 23 is fully inserted into the interior of the first connecting groove 24, the passive rack 29 is also inserted into the interior of the connecting cavity 31 to the limit. At this time, the squeezing force of the inner wall of the connecting cavity 31 on the connecting block 34 disappears. At this time, the connecting block 34 returns to its original position under the action of the restoring force of the first spring 33, and is inserted into the interior of the second connecting groove 35 and engages with the second connecting groove 35. At this time, the lower pipe pile 1 and the upper pipe pile 2 can be connected through the combined action of the connecting block 34 and the second connecting groove 35.

[0022] Further, the external fixing component includes a movable groove 38, which is opened on the outer side of the upper connecting seat 21, and the top of the external fixing card 39 is sleeved inside the movable groove 38. The bottom of the top of the external fixing card 39 is provided with a reset component, and the bottom end of the external fixing card 39 is engaged with the fixed groove 43. The fixed groove 43 is opened on the outer side of the lower connecting seat 22, and the fixed groove 43 is communicated with the first connecting groove 24. The reset component includes a second slide groove 40, and the second slide groove 40 is opened at the bottom of the top of the external fixing card 39. The second slide groove 40 is slidably connected with a second slider 41 inside, and a second spring 42 is provided inside the second slide groove 40. The second slider 41 is fixedly connected to the inner wall of the movable groove 38, and the bottom end of the external fixing card 39 is provided with an inclined surface on one side close to the lower connecting seat 22, and the second spring 42 is close to the first One end of the second slider 41 is fixedly connected to the second slider 41, and the end of the second spring 42 away from the second slider 41 is fixedly connected to the inner wall of the second slide groove 40; during operation, when the connecting ring 23 moves downward and is inserted into the interior of the first connecting groove 24, the outer fixing card 39 is squeezed by the outer wall of the lower connecting seat 22 under the action of the inclined surface opened at its bottom end, and then moves, so that the second slider 41 slides inside the second slide groove 40 and squeezes the second spring 42, causing the second spring 42 to produce elastic deformation. When the connecting ring 23 is fully inserted into the interior of the first connecting groove 24, the bottom end of the fixing groove 43 is no longer squeezed by the outer wall of the lower connecting seat 22. At this time, the outer fixing card 39 returns to its original position under the action of the restoring force of the second spring 42 and is inserted into the interior of the fixing groove 43, thereby playing the effect of auxiliary fixing the connection between the lower pipe pile 1 and the upper pipe pile 2.

[0023] Further, the positioning assembly includes an abutment groove 44, which is arranged on the outer side of the bottom end of the connecting ring 23, and the abutment groove 44 cooperates with the positioning block 45, and a sliding groove 46 is arranged at the bottom end of the positioning block 45, and a guide rod 47 is fixedly connected to the inside of the sliding groove 46, and a sliding block 48 is sleeved on the outer side of the guide rod 47, and a third spring 49 is also wound around the outer side of the guide rod 47, and the bottom end of the sliding block 48 is fixedly connected to the bottom end of the inner wall of the first connecting groove 24, and an inclined surface is arranged on the top of the positioning block 45, and the side of the third spring 49 close to the sliding block 48 is fixedly connected to the sliding block 48, and the side of the third spring 49 away from the sliding block 48 is fixedly connected to the inner wall of the sliding groove 46; during operation, when the connecting ring 23 is inserted into the first connecting groove 24, the abutment groove 44 arranged at the bottom end of the connecting ring 23 squeezes the inclined surface arranged on the positioning block 45, so that the positioning block 4 Under the action of the extrusion force, the positioning block 45 moves toward the fixed groove 43 until the positioning block 45 is stuck between the fixed groove 43 and the abutting groove 44. At this time, the positioning block 45 moves to the limit, and the connecting ring 23 is also completely inserted into the first connecting groove 24. The rotation of the connecting ring 23 can be limited by the cooperation between the positioning block 45, the abutting groove 44 and the fixed groove 43, so as to prevent the lower pipe pile 1 and the upper pipe pile 2 from being able to rotate relative to each other after being connected. At the same time, the stability of the connection between the lower pipe pile 1 and the upper pipe pile 2 can be further enhanced. When the positioning block 45 is moving, the sliding block 48 slides inside the sliding groove 46 opened at the bottom end of the positioning block 45, and squeezes the third spring 49 wound around the outer side of the guide rod 47, so that the third spring 49 is elastically deformed under the action of the extrusion force, and the positioning block 45 is stably maintained in the gap between the fixed groove 43 and the abutting groove 44 by the restoring force of the third spring 49.
