[0026] The bottom of the lifting seat 12 is fixedly connected to a pressure rod 16, the bottom end of the pressure rod 16 is movably connected to a movable rod 17, the movable rod 17 is fixedly connected to the mounting slide 8, the bottom of the lifting rod 7 is fixedly connected to a mounting plate 6, the bottom of the mounting plate 6 is fixedly connected to a moving seat 2, and one side of the moving seat 2 is fixedly connected to a mounting assembly.

[0027] As can be seen from the above, by starting the pressure rod 16, the pressure rod 16 pushes against the mounting slide 8 to apply a thrust downward, and the movable rod 17 shrinks into the pressure rod 16. At the same time, the thrust will act on the pile rod on the fixed seat 9 through the mounting slide 8, so that the pile rod has a downward thrust to pierce the soil and squeeze the soil, so that the buffering force of the soil is minimized, and then the hydraulic press 3 is started. The hydraulic press 3 starts the pile hammer 14 through the hydraulic pipe 15. At this time, the pile hammer 14 will hammer the pile rod and the pile rod will pierce the soil and move downward. At the same time, the pile rod drives the mounting slide 8 to move downward through the fixed seat 9, and the movable rod 17 will move out of the pressure rod 16.

[0028] Embodiment 2: The lifting mechanism includes an adjusting motor 19, an adjusting screw 20 and a nut seat 21. The adjusting motor 19 is fixedly connected to the top of the top seat 18. The driving end of the adjusting motor 19 is fixedly connected to the adjusting screw 20. The outer side of the adjusting screw 20 is threadedly connected to the nut seat 21. The nut seat 21 is fixedly connected to the lifting seat 12.

[0036] Embodiment 6: Two lifting rods 7 are provided, and both lifting rods 7 are made of metal material, and the outer surface of the lifting rods 7 is smooth.

[0037] As can be seen from the above, the lifting rod 7 made of metal material is more sturdy and durable, and the outer surface of the lifting rod 7 is smooth so that the mounting slide 8 and the lifting seat 12 can slide better.

[0038] Working principle: When using a pile driver for highway construction, the worker inserts the pile rod into the limit opening 5 at the top of the limit plate 4, and then places the top end of the pile rod in the fixing opening 11 of the fixing seat 9 and fixes it with a fixing screw 10. When the pile is installed and piled, the pressure rod 16 is started, and the pressure rod 16 pushes the installation slide 8 downward to apply thrust, and the movable rod 17 shrinks into the pressure rod 16. At the same time, the thrust will act on the pile rod on the fixing seat 9 through the installation slide 8, so that the pile rod has a downward thrust to pierce the soil and squeeze the soil, so that the buffering force of the soil is reduced to the maximum, and then the hydraulic press 3 is started, and the hydraulic press 3 is hydraulically pressed. The pipe 15 starts the pile hammer 14, at this time the pile hammer 14 will hammer the pile rod and the pile rod will pierce the soil and move downward, at the same time the pile rod drives the mounting slide 8 to move downward through the fixed seat 9, and the movable rod 17 will move out of the pressure rod 16, when it descends to a certain depth, the adjusting motor 19 drives the adjusting screw rod 20 to rotate clockwise, and the nut seat 21 will drive the lifting seat 12 to move downward through the lifting rod 7, adjust the position between the lifting seat 12 and the mounting slide 8, and then the pressure rod 16 will start again and apply thrust, thus completing the use process of the utility model, the utility model has a simple structure, and is safe and convenient to use.
