[0030] The swing mechanism 4 includes a mating spline shaft 41, which is molded with the top of the drill rod 32. The outside of the mating spline shaft 41 is slidably connected with a mating sleeve 44 through a spline groove. An anti-slip ring 42 is molded on the top of the mating spline shaft 41. A swing spring 43 is installed between the mating spline shaft 41 and the mating sleeve 44 and on the outside of the mating spline shaft 41.

[0031] In this embodiment, the power mechanism 2 includes an electric motor 21, a pulley reduction assembly 22 is installed at the power output end of the electric motor 21, and the power output end of the pulley reduction assembly 22 is connected to a bevel gear reduction assembly 23. The pulley reduction assembly 22 and the bevel gear reduction assembly 23 are both externally connected to the lifting frame 14 of the support mechanism 1, and the bevel gear reduction assembly 23 includes an active bevel gear and a passive bevel gear, and the passive bevel gear is fixedly connected to the main rod 33.

[0032] In this embodiment, the safety mechanism 5 includes an extrusion screw 51, a groove is formed on the bottom surface of the extrusion screw 51, a sliding shaft is formed on the top of the main rod 33, the sliding shaft is slidably connected in the groove of the extrusion screw 51, a fixed seat is installed on the outside of the extrusion screw 51, the extrusion screw 51 is connected to the fixed seat through a thread, a first pressure plate 53 is formed on the bottom surface of the extrusion screw 51, a second pressure plate 54 is fixedly connected to the top of the main rod 33, a safety spring 52 is installed between the first pressure plate 53 and the second pressure plate 54, and the safety spring 52 is sleeved on the outside of the sliding shaft of the main rod 33.

[0033] In this embodiment, the support mechanism 1 includes a frame 11, a base 12 is installed at the bottom of the frame 11, a moving wheel 13 is arranged at the bottom of the base 12, a lifting frame 14 is connected to the frame 11 by sliding, an auxiliary spring 15 is installed at the lower end of the lifting frame 14 outside the frame 11, and a handle 16 is installed on the side of the lifting frame 14.

[0034] In this embodiment, the top of the drill bit 31 is connected to the drill rod 32 via a thread, and the drill bit 31 is a spiral blade drill bit.

[0035] In this embodiment, the matching spline shaft 41 swings up and down on the matching sleeve 44 by an amplitude of 0-5 cm.

[0036] In this embodiment, a hexagonal groove is formed on the top surface of the extrusion screw 51 .

[0037] Working principle: according to the specifications of the hole to be drilled, select a drill bit 31 of appropriate size, fix the drill bit 31 to the bottom of the drill rod 32 through the thread, align it with the position where the hole needs to be drilled, and rotate the extrusion screw 51 at the same time, so that the first pressure plate 53 squeezes the second pressure plate 54 through the safety spring 52, so that the second pressure plate 54 drives the main rod 33 and the passive bevel gear to be pressed on the active bevel gear, so that the passive bevel gear and the active bevel gear are meshed;

After the main rod 33 drives the drill bit 31 to rotate, the drill bit 31 is pressed down by the handle 16. At this time, because a matching spline shaft 41 and a swing spring 43 are provided between the main rod 33 and the drill rod 32, the swing spring 43 swings up and down slightly in combination with the downward pressure and the reverse resistance provided by the ground, and the up and down swing assists the drill bit 31 to drill a hole;

[0039] During the drilling process, if the drill bit 31 encounters a stone or hard object, it may be locked. At this time, because the power end continues to provide positive torque to the drill bit 31, the reverse torque at the moment of jamming is transmitted to the active bevel gear and the passive bevel gear through the main rod 33. At this time, because there is space at the safety spring 52 at the top of the main rod 33, the torque is converted into axial power to squeeze the safety spring 52, so that the passive bevel gear moves up and disengages from the active bevel gear, avoiding jamming and causing the equipment to overturn or damage to the drill bit 31.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
