[0037] Please refer to Figures 1-2The surfaces of the upper capsule 302 and the lower capsule 303 are coated with white lime powder, and the printing plate 207 is black, through the above setting, the printing plate 207 can leave a clearer mark when contacting the upper capsule 302 or the lower capsule 303, and it is more convenient to measure. The inside of the upper capsule 302 and the lower capsule 303 is filled with thermoplastic resin, and the inside of the base plate 301 is provided with a heating block. Before using the positioning device 3, the thermoplastic resin inside the upper capsule 302 and the lower capsule 303 can be heated to soften, and then hoisted between the pile hammer 4 and the pile 5 for positioning. At this time, after the thermoplastic resin cools and solidifies, the positioning device 3 is removed. Through the above setting, the upper capsule 302 and the lower capsule 303 can be shaped.

[0038] Please refer to Figures 4-6 The inner wall of the horizontal plate 206 close to the rotating shaft 208 is provided with an inner groove 211, and the inner wall of the inner groove 211 is fixedly connected with a touch switch 209. The outer wall of the rotating shaft 208 close to the touch switch 209 is fixedly connected with a touch rod 210, and the touch rod 210 is located below the touch switch 209. The touch switch 209 is electrically connected with the reversible motor 205. If the printing plate 207 touches the upper capsule 302 and the lower capsule 303 during the descending process, the printing plate 207 will rotate clockwise. When the printing plate 207 rotates clockwise, the touch rod 210 is driven to rotate clockwise by the rotating shaft 208, and the touch switch 209 is triggered. At this time, the reversible motor 205 can be reversed. Through the above setting, when the printing plate 207 contacts the upper capsule 302 or the lower capsule 303, the reversible motor 205 can be automatically controlled to reverse. The bottom surface of the horizontal plate 206 is fixedly connected with a C-shaped touch switch 209, one end of the touch switch 209 is attached to the bottom surface of the printing plate 207. Through the above setting, the printing plate 207 can be kept in a horizontal state and can only rotate clockwise.

[0039] Please refer to Figures 8-9The outer wall of the substrate 301 is fixedly connected with a plurality of evenly distributed pressure relief devices. The pressure relief device comprises an outer pipe 6 fixedly connected with the side wall of the substrate 301. The side wall of the outer pipe 6 is fixedly connected with a connecting pipe 7. The side wall of the connecting pipe 7 is fixedly connected with a negative pressure pipe 601. Branch pipes 707 are in communication between the outer pipe 6 and the upper capsule 302 and the lower capsule 303. A soft pipe 702 is in communication between the negative pressure pipe 601 and the outer pipe 6. A piston 602 is slidably connected with the inner wall of the negative pressure pipe 601. The side wall of the piston 602 is fixedly connected with a push-pull rod 603. One end of the push-pull rod 603 is threadedly connected with the side wall of the negative pressure pipe 601. The top end of the connecting pipe 7 is fixedly connected with a connecting pipe 701. The top end of the connecting pipe 701 is rotatably connected with a linkage rod 706. An installation groove is formed in the inner portion of the connecting pipe 701. A baffle 705 is fixedly connected with the outer wall of the linkage rod 706 close to the installation groove. A compression spring 704 is fixedly connected between the top end of the installation groove and the baffle 705. A pressing block 703 and the compression spring 704 are fixedly connected with the bottom end and the top end of the linkage rod 706, respectively. An electromagnet 709 is fixedly connected with the top end of the connecting pipe 701. The electromagnet 709 is located on the upper side of an iron sheet 708. After the upper capsule 302 and the lower capsule 303 are extruded, the upper capsule 302 and the lower capsule 303 located on the outer side of the pile driver 4 and the pile 5 are also convex. The convex degree may be comparable to the convex condition on the inner side of the pile driver 4 and the pile 5. Therefore, it cannot be ensured that the convex point on the inner side of the pile driver 4 and the pile 5 is the highest point. It is not convenient to observe the center point of the pile driver 4 and the pile 5. In the initial state, under the action of the compression spring 704 and the baffle 705, the linkage rod 706 has a downward moving force and the pressing block 703 extrudes the soft pipe 702, so that the soft pipe 702 is in a sealed state. Before the positioning device 3 is hoisted, the push-pull rod 603 can be rotated to drive the piston 602 to move leftward. The inner portion of the negative pressure pipe 601 is in a negative pressure state. After the positioning device 3, the pile driver 4 and the pile 5 are all placed in position, the electromagnet 709 is started and drives the pressing block 703 to move upward through the iron sheet 708 and the linkage rod 706. At this time, the soft pipe 702 is no longer extruded and is in a communication state. The thermoplastic resin located on the outer circle of the pile driver 4 and the pile 5 can be sucked into the inner portion of the negative pressure pipe 601. The convex height on the outer side of the pile driver 4 and the pile 5 can be prevented from being greater than the convex height on the inner circle thereof. The center positioning is more accurate.

[0040] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical solution and the improved concept of the present application within the technical range disclosed by the present application.
