With the development of society and economy at a fast pace, the pursuit of people for leisure and entertainment becomes a trend, and fishing is a popular leisure and entertainment item among people. Generally, people only need to prepare related fishing gear during fishing, and can enjoy the fishing fun. However, in seasons or areas with low temperatures, the river surface is often in a frozen state, and people need to make ice holes on the ice layer to fish. However, the conventional method for drilling ice holes is to use iron drill and manually file holes in the ice layer, which is time-consuming and labor-consuming.

With the continuous development of society, people gradually start to use an internal combustion engine as power to drive a drill bit to drill holes and drill the ground. With the development of handheld high-torque lithium electric drills, electric drills with the maximum output torque larger than 100NM are successively introduced by Milwaukee corporation and Makita corporation, and the handheld lithium electric drills are made possible to be used for ice-drilling fishing and ground-drilling tree planting.

"do good job, must benefit its ware earlier", has been used for the suitable power tool in open air, still needs to dispose suitable drill bit. Especially when drilling on the surface of water ice sheet, if use current old-fashioned earth boring bit structure, people when drilling, probably because of the centre gripping between drill bit and the power tool not fastening enough on the one hand, let the drill bit fall into under water because drill bit and power tool centre gripping position are not hard up when the ice sheet is bored and is worn. On the other hand, the power tool may not continue to operate due to other factors such as insufficient power supplied by the electric drill, insufficient fuel of the internal combustion engine, objective environment, and the like. In view of the foregoing, there is a need for optimization, improvement and expansion of existing drill bits.
