Embodiment
According to Fig. 1,2, flexible axle is connected the present invention relates to a kind of electric hand drill, it includes flexible axle output end 1 and flexible axle connectsEnd 2 is connect, between the flexible axle output end 1 and flexible axle connection end 2 by some Universal rotary trochanters 10 with axially extending bore 12 successivelyConnection, the left end of the flexible axle output end 1 and the Universal rotary trochanter 10 is integral to be provided with cone 8 of the end with spheroid 9,The right-hand member of the flexible axle connection end 2 and the Universal rotary trochanter 10 is integral provided with the holding tank being adapted with the spheroid 914, being provided with 3rd bearing 11, the flexible axle output end 1 for the interior interval of the Universal rotary trochanter 10 is provided with two clutch shaft bearings 3, outsideThe output flexible shaft joint end 4 for stretching out the end of flexible axle output end 1, an electric hand drill card are set with the clutch shaft bearing 3 of sideDisk 13 is connected on the output flexible shaft joint end 4；Second bearing 5, the second bearing 5 are provided with the flexible axle connection end 2The connecting portion 6 for stretching out the end of flexible axle connection end 2 is inside set with, specifically：The connecting portion 6 of the flexible axle connection end 2 isBolt collar or electric drill clamping joint；One flexible axle 7 is fixedly connected with the rear other end with the left end of the output flexible shaft joint end 4 and worn successivelyCross described after the inwall, the axially extending bore 12 of the Universal rotary trochanter 10 and the inwall of the second bearing 5 of the clutch shaft bearing 3The right-hand member of bolt collar 6 is fixedly connected；In use, by the clamping output flexible shaft joint end 4 of electric hand drill chuck 13, because flexible axle is defeatedGo out between end 1 and flexible axle connection end 2 and be sequentially connected by some Universal rotary trochanters 10 with axially extending bore 12, and flexible axle 7 and instituteThe left end for stating output flexible shaft joint end 4 is fixedly connected with the rear other end and sequentially passes through the inwall of the clutch shaft bearing 3, the Universal rotaryThe axially extending bore 12 of trochanter 10 is fixedly connected with the right-hand member of the connecting portion 6 after the inwall of the second bearing 5, can bend orExtend each Universal rotary trochanter 10, each Universal rotary trochanter 10 can be by the connecting portion 6 such as bolt sleeve of the end of flexible axle connection end 2 after bendingJacket casing is on the bolt nut in any smaller space, or the connecting portion 6 such as electric drill clamping joint card for passing through the end of flexible axle connection end 2Drill bit is connect, when electric hand drill is rotated forward after switching on power, the rotation of output flexible shaft joint end drives bolt collar rotation and right by flexible axle 7Bolt is fastened, or the rotation of output flexible shaft joint end drives bit by flexible axle 7 and drilled；Electric hand drill connects electricityWhen being inverted behind source, the rotation of output flexible shaft joint end drives bolt collar to rotate and loosened to bolt by flexible axle 7, or outputThe rotation of flexible axle joint end drives bit drill bit is exited drilling by flexible axle 7；Be achieved in that it is simple in construction, can be polygonalDegree bending extension and the effect that multi-angle bending extension punching or fastening bolt can be carried out in smaller space.
