Abstract

The invention discloses an electric drill with the drill bit diameter being adjustable. The electric drill is composed of a machine body assembly, a clutch sliding sleeve, a hydraulic adjusting assembly and an expandable drill bit. The expandable drill bit is adopted, the thickness of the drill bit can be adjusted through the oil charging amount according to the requirements, stepless gradually varied adjustment can be achieved, the machining requirement of holes within a certain range is met, the drill bit does not needed to be replaced, the situation of infirm mounting due to frequent drill bit replacement is avoided, and the working safety is improved; an output shaft is used for providing power for the hydraulic adjusting assembly and the expandable drill bit, power switching is achieved through the clutch sliding sleeve, the adjustment difficulty of the expandable drill bit is lowered, operation is more convenient, rapid and convenient, the part utilization rate is increased to the maximum, an existing structure can still be used, the machine body assembly does not need to be modified, and machining implementation is easier.

Description

[0001] This application is a divisional application with application number 2014103342710, application date July 14, 2014, and invention title "An electric drill with adjustable drill bit diameter and its use method". technical field [0002] The invention relates to an electric tool, in particular to an electric drill for opening holes and a use method thereof. Background technique [0003] 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 ...
