Abstract
The utility model relates to a multi-purpose electric hand drill, comprising a motor and a driving mechanism. The multi-purpose electric hand drill is characterized in that a universal coupling is arranged in the driving mechanism, and the front part of the universal coupling is provided with a drive shaft; a casing is provided with a shaft sleeve rack; the shaft sleeve rack is provided with an arched hollow slot; screws for fixing the drive shaft is arranged in the hollow slot. The universal coupling is arranged in the drive system of the electric hand drill of the utility model, the direction of a drill bit is changed, and thus convenience is provided for drilling a plurality of special parts. Simultaneously the front part of the drive shaft is provided with a shaft clamp for placing a grinding wheel or a cutterhead. Therefore, the utility model can be used as a multi-purpose tool for drilling, grinding, planing and cutting.
Description
The utility model is a kind of instrument, particularly a kind of electric hand drills of using more.
General electric hand drill can not change angle at present, therefore uses very inconvenience in some occasion, and drill bit can only be installed in existing electric hand drill front portion simultaneously, so can not use as other instrument.
The purpose of this utility model provides a kind of novel electric hand drill, and it can overcome existing shortcoming in the prior art, accomplishes that drill bit can change angle, makes it use more convenient in some special occasions.
The purpose of this utility model is achieved in that it comprises motor and transmission mechanism, it is characterized in that being equipped with in the transmission mechanism universal coupling, power transmission shaft is equipped with in front portion at universal coupling, the axle sleeve frame is installed on the casing, have the arc dead slot on the axle sleeve frame, the screw that the fixed conveyor axle sleeve is used is housed in the dead slot.
The utility model is equipped with universal coupling in the transmission system of electric hand drill, the direction of drill bit is changed, and provides convenience for the boring of carrying out some privileged sites like this.
The best angle of the arc dead slot on the casing is 45 °.
For realizing a tractor serves several purposes of electric hand drill, can add an axle card in the front of power transmission shaft, in the front of axle card emery wheel or circular cutter can be installed, the all-purpose instrument that makes electric hand drill can be used as brill, grind, dig, cut.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of a kind of specific embodiment of the present utility model.
Fig. 2 is that the B of Fig. 1 is to view.
A is the motor and the casing of electric hand drill among the figure, in this figure, omit and do not mark, its front portion is a transmission mechanism, the back of transmission mechanism is a gearbox 9, change-speed gearing 10 is housed, be screwed on the frame of electric hand drill by connecting plate 4, universal coupling 1 is equipped with in the front of change-speed gearing, and the power transmission shaft 2 that band hemispherical fork is equipped with in the front of universal coupling is equipped with axle sleeve 3 on power transmission shaft, axle sleeve frame 5 also is housed on the connecting plate, have arc dead slot 6 on the axle sleeve frame, the handle 11 of band screw be housed in the arc dead slot, with the angle adjustment of power transmission shaft good after, with handle axle sleeve is withstood, make the fixed angle of power transmission shaft.The angle of arc dead slot is 45 ° in the present embodiment, and power transmission shaft is changed between 0-45 ° of angle.Front end at power transmission shaft is equipped with axle card 7, and emery wheel or blade can be equipped with in the front of axle card, for guaranteeing safety, in the outside of axle card and emery wheel safety guard 8 are housed.
