Abstract

The invention discloses an electric drill capable of adjusting the diameter of a drill bit. The electric drill comprises a machine body assembly, a clutch sliding sleeve, a hydraulic adjusting assembly and an expandable drill bit. Due to the adoption of the expandable drill bit, the thickness of the drill bit can be adjusted by using the oil mass according to the requirements, the stepless gradient adjustment can be realized, the processing requirement of aperture within a certain range is easily met without the replacement of the drill bit, the condition that the mounting is not firm due to frequent replacement of the drill bit is avoided, and the operation safety is improved; the hydraulic adjusting assembly and the expandable drill bit are powered by one output shaft; power switch is realized by the clutch sliding sleeve, and the adjusting difficulty of the expandable drill bit is reduced, so that the operation for the expandable drill bit is more convenient and quicker; the utilization rate of parts is improved to the maximum extent, so that the machine body assembly can use the existing structure without changing, and the processing and the implementation are realized more easily.

Description

technical field [0001] The invention relates to an electric tool, in particular to an electric drill for opening holes and a use method thereof. Background technique [0002] Electric drill is a kind of commonly used drilling tool, and it all has extensive application in the fields such as construction, industry, medicine. The current electric drill is usually composed of an electric drill main body and a drill bit. The drill bit is usually provided with various diameters and specifications, and an appropriate combination of the drill bit and the electric drill main body can be selected for use according to needs. At present, the electric drill with this structure has the following disadvantages: during the use of the electric drill, it is often necessary to replace the drill bit back and forth according to the difference in the aperture to be processed, which is troublesome to operate, and the frequent replacement of the drill bit increases the occurrence of unsteady fixati...
