When the hollow special-shaped swing rod 51 swings outwards and opens, the hollow special-shaped swing rod 51 drives the sleeve 73 to swing downwards, the sleeve 73 swings downwards to drive the contact rod 72 to swing downwards, the contact rod 72 swings downwards to slide on the arc-shaped strip 71, the arc-shaped strip 71 enables the contact rod 72 to move inwards, the contact rod 72 moves inwards to drive the sleeve 73 to move inwards, the sleeve 73 moves inwards to drive the clamping rod 74 to move inwards through the first spring 75, the clamping rod 74 moves inwards to be in contact with the outer wall of the steel pipe pile 1, the clamping rod 74 is limited by the steel pipe pile 1, the sleeve 73 continues to move inwards to enable the first spring 75 to be compressed, the clamping rod 74 swings downwards continuously along with the clamping rod 74, when the clamping rod 74 swings corresponding to the clamping groove 76, the clamping rod 74 moves inwards to be inserted into the clamping groove 76 under the action of the first spring 75, the clamping rod 74 is matched with the clamping groove 76 to fix the sleeve 73, the hollow special-shaped swing rod 51 is fixed, and the hollow special-shaped swing rod 51 stops swinging outwards. Therefore, the hollow special-shaped swing rod 51 can be stably inserted into the soil, and the fixing of the steel pipe pile 1 is not affected.

When concrete is poured into the steel pipe pile 1, the concrete is in contact with the round block 81, the round block 81 is driven by the concrete to move downwards, the round block 81 moves downwards to drive the sliding rod 82 to move downwards, the sliding rod 82 moves downwards to drive the movable plate 84 to move downwards, the second spring 83 is compressed, the movable plate 84 continuously moves downwards along with the continuous pouring of the concrete, the movable plate 84 moves downwards and moves downwards together with the trigger block 88, the trigger block 88 moves downwards to drive the stay wire 810 to move downwards, the stay wire 810 moves downwards to drive the clamping block 85 to move inwards through the wire guide wheel 87, the third spring 86 is stretched, the clamping block 85 moves inwards to be separated from the limiting groove 89, due to the weight of the concrete in the steel pipe pile 1, the concrete drives the hollow round block 3 to move downwards rapidly through the round block 81, the hollow round block 3 moves downwards rapidly to drive the L-shaped rod 42 to move downwards, and the hollow swing rod 51 is also rapidly swung outwards into the concrete. Thus, the hollow special-shaped swing rod 51 can quickly swing into the soil to fix the steel pipe pile 1.

Referring to fig. 1, 2, 3, 4, 8 and 16, the portable electronic device further includes a ring 9, a limiting block 10 and a fourth spring 11, the ring 9 is slidably connected to the middle of the top of the housing 2 in a penetrating manner, the limiting block 10 is fixedly connected to the bottom end of the ring 9, the fourth spring 11 is connected between the top of the limiting block 10 and the top of the housing 2, and the fourth spring 11 is wound on the ring 9.

The novel shell is characterized by further comprising a baffle 12 and five springs 13, five baffles 12 are arranged inside the shell 2 in a sliding mode at uniform intervals, the baffles 12 correspond to the hollow special-shaped swing rod 51, the baffles 12 are in contact fit with the hollow special-shaped swing rod 51, and the top of each baffle 12 is connected with the inner side of the shell 2 at three fifth springs 13 at uniform intervals.

When steel-pipe pile 1 is buried into soil as required, the couple of lifting by crane the machine is hung on ring 9, the rethread lifts by crane the machine and drives ring 9 rebound, ring 9 rebound drives stopper 10 rebound, fourth spring 11 is compressed, when stopper 10 rebound to the maximum stroke, stopper 10 drives steel-pipe pile 1 rebound and is hoisted, can put steel-pipe pile 1 into soil, the couple of lifting by crane the machine is taken off from ring 9 again, because of the effect of fourth spring 11, stopper 10 drives ring 9 rebound and resets. Therefore, the steel pipe pile 1 can be more stable in the moving process.

When the steel pipe pile 1 is buried in the soil, the baffle 12 can block the soil, and further when the hollow special-shaped swing rod 51 swings outwards, the hollow special-shaped swing rod 51 drives the baffle 12 to move upwards, the fifth spring 13 is compressed, and when the hollow special-shaped swing rod 51 stops swinging outwards, the hollow special-shaped swing rod 51 stops driving the baffle 12 to move upwards. In this way, soil can be prevented from falling into the housing 2 and affecting the engagement between the large gear 53 and the tooth block 43.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
