The invention relates to an energy feedback type electric drill allowing manual power generation and a driving method of the electric drill. The electric drill comprises a variable-pitch spiral bit, wherein the spiral bit is driven by an energy feedback device which comprises a closed casing, a non-magnetic shaft is axially arranged in the middle in the casing, at least eight permanent magnets magnetized with a Halbach array are arranged on the circumferential side of the non-magnetic shaft from top to bottom, a plurality of coils wind around the permanent magnets from top to bottom, the coils are connected with a storage battery panel and embedded in the inner circumferential side of the casing, and the storage battery panel is fixed in two ends of the casing; one end of the non-magnetic shaft is in threaded connection with one end of the spiral bit and driven by a driving mechanism, and the driving mechanism comprises a transmission shaft which is in threaded connection with the other end of the non-magnetic shaft. The electric drill is simple in overall structure, reliable in running, small in size, light, high in efficiency and mainly applicable to mountain or surface drilling in fields.
Description
technical field [0001] The invention relates to the field of electric drills, in particular to an electric drill capable of manually generating power and feeding energy and a driving method thereof. Background technique [0002] When the current electric drill is drilling, the drill bit rotates at a high speed under the drive of the drill bit motor, thereby realizing automatic electric drilling. But for outdoor work in the field, it is necessary to carry batteries, which is not practical for long-distance trekking. Contents of the invention [0003] The object of the present invention is to address the above deficiencies and provide an electric drill capable of manually generating power and feeding energy and its use method, so as to realize drilling with manual power generation. [0004] The solution adopted by the present invention to solve the technical problem is: an electric drill capable of manually generating power and feeding energy, including a variable-pitch aug...
