The hexagonal rod 4c1 is used for transmitting torque to the lead screw 4c, and the staff opens the second cover plate 2a and can expose the hexagonal rod 4c1, and then the staff can rotate the lead screw 4c by inserting the hexagonal socket wrench into the hexagonal rod 4c 1.

The pulley transmission mechanism 4g comprises a fixed pulley 4g1 and a belt 4g2, the fixed pulley 4g1 is fixedly installed on one surface, facing the second bearing flange 4b, of the first bearing flange 4a, at least two fixed pulleys 4g1 are arranged, the fixed pulleys 4g1 are uniformly distributed around the axis of the screw rod 4c, the belt 4g2 corresponds to the fixed pulleys 4g1 in a one-to-one mode, and the belt 4g2 is fixedly connected with the top surfaces of the screw rod nut 4e and the sliding sleeve 4f respectively by winding the fixed pulleys 4g 1.

When the screw nut 4e moves vertically downwards, the screw nut 4e pulls one end fixedly connected with the belt 4g2 to move downwards, and the belt 4g2 bypasses the fixed pulley 4g1 and one end fixedly connected with the sliding sleeve 4f moves upwards, so that the screw nut 4e and the sliding sleeve 4f are close to each other; when the feed screw nut 4e moves vertically upward, the slide sleeve 4f falls naturally under the action of gravity, and the slide sleeve 4f and the pulley transmission mechanism 4g move the same distance all the time through the belt 4g 2.

The feed screw nut 4e is provided with a third cantilever 4e1 which radially penetrates through the ground pile 2 outwards and the suspended end of which extends to the outer side of the ground pile 2, the third cantilever 4e1 corresponds to the first connecting rod 5 one by one, and one end of the first connecting rod 5 is hinged with the suspended end of the third cantilever 4e 1; the sliding sleeve 4f is provided with a fourth cantilever 4f1 which penetrates through the ground pile 2 radially outwards and has a suspended end extending to the outer side of the ground pile 2, the fourth cantilever 4f1 corresponds to the second connecting rod 6 one by one, and one end of the second connecting rod 6 is hinged with the suspended end of the fourth cantilever 4f 1.

The third and fourth suspension arms 4e1 and 4f1 are used to hinge the first and second links 5 and 6, respectively, such that the lead screw nut 4e and the sliding sleeve 4f are located inside the pile 2 while the first and second links 5 and 6 are located outside the pile 2, such that the housing of the pile 2 does not interfere with the outward protruding movement of the hinged ends of the first and second links 5 and 6.

The linear bidirectional sliding table 4 further comprises a second guide mechanism 4i, the second guide mechanism 4i comprises a first sliding column 4i1, a second sliding column 4i2 and a connecting rod 4i3, the first sliding column 4i1 is horizontally slidably mounted on the third cantilever 4e1 and the first kidney-shaped hole 4e2, the second sliding column 4i2 is vertically slidably mounted on the first connecting rod 5 and the second connecting rod 6, and the adjacent first sliding column 4i1 and the second sliding column 4i2 are movably connected through the connecting rod 4i 3.

A first kidney-shaped hole 4e2 horizontally penetrating through the third cantilever 4e1 is formed in the third cantilever 4e1, a second kidney-shaped hole 5a horizontally penetrating through the first connecting rod 5 is formed in the first connecting rod 5, the length direction of the third cantilever 4e1 is horizontally arranged, the length direction of the second kidney-shaped hole 5a is vertically arranged, a first sliding column 4i1 is slidably arranged in the first kidney-shaped hole 4e2, a second sliding column 4i2 is slidably arranged in the second kidney-shaped hole 5a, when the screw nut 4e and the sliding sleeve 4f are close to each other, the first connecting rod 5 can protrude outwards or inwards, and the connecting rod 4i3 limits the included angle between the third cantilever 4e1 and the first connecting rod 5 through the first sliding column 4i1 and the second sliding column 4i2, so that the first connecting rod 5 can only rotate outwards, and the first connecting rod 5 is prevented from protruding inwards; the same mechanism is also mounted on the fourth suspension arm 4f1 and the second link 6 so that both the first link 5 and the second link 6 can only protrude outward.

The working principle of the invention is as follows:

the worker fixedly installs the embedded cylinder 1 in the concrete foundation through fasteners such as anchor bolts and embedded bolts, then places the ground pile 2 in the embedded cylinder 1 and fixedly connects the embedded cylinder 1 and the ground pile 2 through bolts, because the bolts are not connected tightly enough, in order to ensure that the ground pile 2 is not separated from the embedded cylinder 1, the worker can open the second cover plate 2a, then insert a hand-held inner hexagonal socket wrench into the hexagonal rod 4c1 to rotate the lead screw 4c, thereby enabling the lead screw nut 4e to vertically move downwards along the axis of the lead screw 4c through threads, because the lead screw nut 4e and the sliding sleeve 4f are in transmission connection through the pulley transmission mechanism 4g, when the lead screw nut 4e moves, the sliding sleeve 4f moves towards the direction opposite to the lead screw nut 4e under the action of the pulley transmission mechanism 4g, thereby enabling the lead screw nut 4e and the sliding sleeve 4f to synchronously move backwards by rotating the lead screw 4c, when the screw nut 4e and the sliding sleeve 4f move synchronously and approach each other, the first connecting rod 5 and the second connecting rod 6 protrude outwards to enable the hinged end of the first connecting rod 5 and the hinged end of the second connecting rod 6 to abut against one end, far away from the plug 3b, of the rotating rod 3a, the rotating rod 3a rotates around the axis of the hinge 1b, the plug 3b moves towards the fan-shaped flange 2b1, the plug 3b is further connected onto the fan-shaped flange 2b1 in a clamping mode, and therefore the plug pin 3 can clamp the ground pile 2 and cannot be disengaged from the inside of the embedded cylinder 1.
