Abstract
The utility model discloses an improved electric hand drill which comprises a machine shell, a gearbox, a stator and a rotor. The gearbox and the stator are assembled in the machine shell. The rotor is arranged in the stator. A gear is arranged in the gearbox and in sliding fit with an output shaft. A steel ball hole is drilled in the output shaft. A steel ball is contained in the steel ball hole. A clamping spring is arranged at the front end of the gear. The improved electric hand drill has the advantages that the gear is in sliding fit with the output shaft so that the noise of the gear can be eliminated; the steel ball hole is drilled in the output shaft so that the connection function can be achieved and rotation can be prevented; the clamping spring is arranged at the front end of the gear so that the phenomenon that the gear falls off due to the vibration of a drill body can be prevented; the service life of the improved electric hand drill is prolonged and the assembly efficiency is high.
Description
Technical field
The utility model relates to a kind of electric hand drill, relates in particular to a kind of improved electric hand drill.Belong to field of power tools.
Background technology
Electric hand drill is the most salable product of Power Tools Industries, is widely used in the industries such as building, finishing, furniture, is used on object perforate or pierces object, electric hand drill is in the process of punching, and gear noise is larger, and gear is because the drill body vibrations come off, the electric hand drill life-span is short, and efficiency of assembling is low.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
The utility model content
The purpose of this utility model is to provide a kind of long service life, improved electric hand drill that efficiency of assembling is high.
The technical solution adopted in the utility model is:
A kind of improved electric hand drill, comprise casing, gear-box, stator and rotor, described gear-box and stator are assemblied in casing, described rotor is arranged in stator, be provided with gear in described gear-box, described gear and output shaft are slidably matched, and are drilled with steel ball hole on described output shaft, accommodate steel ball in described steel ball hole, described gear front end is provided with a jump ring.
The beneficial effects of the utility model: gear and output shaft are slidably matched, and have stopped the noise of gear; Be drilled with steel ball hole on output shaft, play connection function, prevent from spinning; The gear front end is provided with a jump ring, prevents that gear from falling down because of drill body vibrations, and electric hand drill long service life, efficiency of assembling are high.
