A domestic guardrail pile driver includes a body, with a compression block fixedly mounted on the top surface of the body. The compression block symmetrically houses hydraulic slides on both sides, with a connecting pipe linking the two hydraulic slides. The bottom wall of the connecting pipe is equipped with a compression groove. The body contains a power chamber, with a piling device for driving piles positioned between the power chamber and the compression block. The piling device includes an air pressure block slidingly installed in the compression groove, and each hydraulic slide slideably mounts a hydraulic slide plate. The bottom surface of each hydraulic slide plate is fixedly mounted with pressure rods that slideably connect with the bottom wall of the hydraulic slide and the top wall of the power chamber. The air pressure block and the hydraulic slide plates contain hydraulic oil. The bottom surface of the pressure rod is fixedly mounted with a piling plate. The rear side wall of the power chamber is fixedly mounted with a power motor, which is frontally connected to a power shaft. The power shaft is fixedly mounted with a small gear. The front side wall of the power chamber rotatably connects a winding wheel and a rotating cylinder, with clamping racks symmetrically slideably connected above and below within the rotating cylinder. The clamping racks are connected to the rotating cylinder with small springs, allowing the small gear to engage with the clamping racks. The clamping racks can drive the winding wheel to rotate. The top surface of the piling plate is fixedly mounted with a pulling ring, with a steel cable connecting the winding wheel and the pulling ring. The bottom wall of the power chamber is equipped with a piling space, which contains a hydraulic device for straightening wooden piles. The right side wall of the piling space houses a rolling chamber, with the right side wall of the rolling chamber housing a working block. The top wall of the working block symmetrically houses passageways, with the top wall of the passageway equipped with a driving space. Between the driving space and the working block, there is a pushing device for propelling wooden piles. The right side wall of the working block houses an insertion chamber, with the rear side of the driving space housing a transmission chamber. The lower side of the rolling chamber is equipped with a connecting shaft, with a baffle device for assisting wooden piles to roll into the hydraulic device positioned between the connecting shaft and the transmission chamber. The right side of the engaging chamber houses a wheel chamber.

The hydraulic device includes a hydraulic machine fixedly mounted on the bottom wall of the piling space, with a connecting shaft rotatably connected to the right side wall of the piling space. The connecting shaft is connected to the right side wall of the piling space with a torsion spring and is fixedly mounted with a straightening plate that can make contact with the hydraulic machine.
