Positioning rods 23 are inserted into the interior of the connecting holes 22, and springs 24 are sleeved on the outer surfaces of the positioning rods 23. Connecting grooves 25 are opened inside the bottom surface of the pile rod 3, and multiple sets of connecting grooves 25 are provided. Positioning holes 26 are opened inside the inner wall surface of the connecting grooves 25, and multiple sets of positioning holes 26 are provided. A limit ring is fixedly connected to the outer surface of the positioning rod 23, and rectangular sliders are fixedly connected to the upper and lower outer surfaces of the limit ring. The inner wall surfaces of the upper and lower ends of the hole 22 are provided with rectangular sliding grooves, and the outer dimensions of the rectangular sliders are adapted to the inner dimensions of the rectangular sliding grooves. The outer surfaces of the two ends of the spring 24 respectively abut against the outer surface of one side of the limiting ring and the inner wall surface of one side of the connecting hole 22. The outer diameter of the limiting ring is the same as the inner diameter of the connecting hole 22. This design allows the positioning rod 23 to move inside the connecting hole 22 and then return to its original position under the elasticity of the spring 24. At the same time, this design allows the positioning rod 23 to move inside the rectangular sliding grooves through the rectangular sliders at the upper and lower ends of the limiting ring, making the positioning rod 23 more stable when moving and preventing the positioning rod 23 from deflecting when moving.

[0027] The outer diameter and height dimension of the connecting rod 21 are the same as the inner diameter and height dimension of the connecting groove 25, the outer surface of one end of the positioning rod 23 is matched with the inner wall surface of the positioning hole 26, and the position of the positioning rod 23 corresponds to the position of the positioning hole 26. This design allows the connecting groove 25 to be sleeved on the outer surface of the connecting rod 21, and makes the connecting groove 25 more stable when it is sleeved on the outer surface of the connecting rod 21. In addition, this design allows one end of the positioning rod 23 to be inserted into the positioning hole 26, and prevents the end of the positioning rod 23 from being separated from the inside of the positioning hole 26.

[0028] Embodiment two

[0029] As Figures 3-5 shown, based on the same concept as the above embodiment, the present embodiment also proposes:

[0030] The bearing structure 4 includes a first receiving groove 41, and the first receiving groove 41 is provided with two groups, and the two groups of first receiving grooves 41 are respectively arranged in the inside of the inner wall surface of the two sides of the pile rod 3. The bearing structure 4 further includes a movable hole 42, and the movable hole 42 is arranged in the inside of the inner wall surface of one side of the first receiving groove 41. A moving sliding groove 43 is arranged in the inside of the upper and lower end inner wall surface of the movable hole 42, and one end of the moving sliding groove 43 is provided with a second receiving groove 44. An activity rod 45 is inserted into the inside of the movable hole 42, and the outer surface of one end of the activity rod 45 is fixedly connected with a receiving plate 46. The outer surface of the upper and lower end of the activity rod 45 is fixedly connected with a moving sliding block 47, and the outer surface of one end of the moving sliding block 47 is fixedly connected with an inclined block 48. A top rod 49 is inserted into the inside of the pile rod 3. The inside dimension of the first receiving groove 41 is the same as the outside dimension of the receiving plate 46. The inside dimension of the movable hole 42 is matched with the outside dimension of the activity rod 45. The inside dimension of the moving sliding groove 43 is matched with the outside dimension of the moving sliding block 47. This design allows the receiving plate 46 to be received in the inside of the first receiving groove 41, thereby avoiding the condition that the receiving plate 46 blocks the top rod 49 when the top rod 49 is inserted into the inside of the pile rod 3. In addition, this design allows the moving sliding block 47 to move synchronously in the inside of the moving sliding groove 43 when the activity rod 45 moves in the inside of the movable hole 42, thereby avoiding the condition that the moving position of the activity rod 45 deviates, and further allowing the activity rod 45 to move more stably in the inside of the movable hole 42.

[0031] The inside dimension of the second receiving groove 44 is matched with the outside dimension of the inclined block 48. The outer surface of the side close to each other of the two groups of receiving plates 46 is matched with the outer surface of the top rod 49. When the pile rod 3 is driven into the ground, the inclined block 48 will not be separated from the inside of the second receiving groove 44, thereby avoiding hindering the driving of the pile rod 3. In addition, this design allows the receiving plate 46 to be pushed outward and moved when the top rod 49 is inserted into the inside of the pile rod 3.

[0032] Working principle: when the device is used, first, the device is placed in a suitable position, the upper end of the pile head 1 is connected with the position of the connecting rod 21, and the bottom of the pile rod 3 is connected with the position of the connecting slot 25, at this time, the connecting slot 25 can be sleeved on the outer surface of the connecting rod 21, and one end of the positioning rod 23 is pushed into the inside of the connecting hole 22, when the connecting slot 25 is completely sleeved on the outer surface of the connecting rod 21, the position of the connecting hole 22 corresponds to the position of the positioning hole 26, then the outer surface of one end of the positioning rod 23 can be reset under the elasticity of the spring 24, so that the outer surface of one end of the positioning rod 23 is inserted into the inside of the positioning hole 26, thereby the connection of the pile head 1 and the pile rod 3 can be completed, and the above operation can be repeated according to the required piling depth to connect the plurality of pile rods 3.

[0033] When the pile head 1 and the pile rod 3 are driven into the ground, the top rod 49 is inserted into the inside of the pile rod 3, and the outer surface of the top rod 49 contacts the outer surface of one side of the storage plate 46, at this time, the top rod 49 can be powered to drive the top rod 49 to pass through the two groups of storage plates 46, thereby driving the two groups of storage plates 46 to move outward and be stored in the inside of the first storage slot 41, and synchronously driving the movable rod 45 to move outward in the inside of the movable hole 42, moving the sliding block 47 to move outward in the inside of the moving sliding groove 43, so that the inclined block 48 is separated from the inside of the second storage slot 44, at this time, the movable rod 45 extends out of the outer surface of the pile rod 3, thereby the lateral friction of the device can be increased, so that the device is prevented from sinking under pressure, and the above is the whole working principle of the utility model.

[0034] Finally, it should be pointed out that: first, in the description of the present application, it should be pointed out that, unless otherwise specified and limited, the terms "installation", "connection", "connection" should be understood broadly, which can be mechanical connection or electrical connection, or the communication between the two elements, or direct connection, "up", "down", "left", "right" and the like are only used to indicate the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may change;

[0035] Secondly: the utility model discloses the embodiment in the drawing, only relates to the structure involved in the embodiment of the present disclosure, other structures can refer to the usual design, in the case of no conflict, the same embodiment and different embodiments of the utility model can be combined with each other;

[0036] Finally: the above is only the preferred embodiment of the utility model, and is not used to limit the utility model, any modification, equivalent replacement, improvement and the like made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
