Description

[Technical Field]

[0001] The present invention relates to the technical field of power drills, and more particularly to a new type of power drill. [Background technology]

[0002] Among the common electric tool products, the electric drill is the one with the greatest demand. Its working principle is that a small-capacity electromagnetic rotary or reciprocating motor operates by cutting a magnetic field, driving a working device through a transmission mechanism, and linking gears to amplify the power of the drill bit, allowing the drill bit to cut and penetrate the surface of an object efficiently.

[0003] However, the drill bits of conventional electric drills have the problem of being inconvenient to attach and detach during use, which has a negative impact on the speed of drill bit replacement and further affects work efficiency. In addition, the connection structure of conventional electric drills is exposed to the outside of the housing, making it easy for accidents to occur due to miscontact. Furthermore, conventional electric drills have a complex structure, making it difficult for non-professionals to operate, and have a limited range of applications.

[0004] Therefore, there is a need to design a new type of power drill to solve the problems existing in the prior art. Summary of the Invention [Problem to be solved by the invention]
