photoswitch 37 is located on the base plate of fixed block 30 tail end by the first photoelectricity seat 39, and described the Two photoswitches 38 are located on the base plate in fixed block 30 centre position by the second photoelectricity seat 40, and described 3rd photoswitch 41 leads to Crossing the 3rd photoelectricity seat 42 to be located between the first photoelectricity seat 37 and the second photoelectricity seat 38 and in straight line, described light barrier 43 is located at On tooth bar 34, light barrier 43 can be made at the first photoswitch the 37, second photoswitch 38 and the 3rd photoelectricity by the slip of tooth bar In the middle of switch 41, fluting position is passed through or gear is at fluting position, as the position judgment of wire drawing, controls motor 31 and drives tooth The slip of bar 34 or stopping, first photoelectricity seat the 39, second photoelectricity seat 40 and the 3rd photoelectricity seat 42 are provided with the notch of elongated, are used for adjusting Saving the position of corresponding photoelectricity seat, it is achieved the stretching distance that wire drawing is different, once screw is delivered to folder by pressure-air by inclined tube 22 Behind 23 inside, this device controls motor 31 and drives tooth bar 34 to slide, to the 3rd photoswitch 41 by light barrier by gear 33 Stopping during the position that 43 block, at this moment wire drawing 26 pulls rack connecting plate 18 and pulls chuck connecting plate 20 and folder by guide rod 16 23 retractions, and compression spring 19, make electric screwdriver bar 21 withstand cap nut in reaching chuck 23, simultaneously electric screwdriver bar 21 instant rotation one Under make the cutter head of electric screwdriver bar 21 recognize in the fluting of cap nut, withstand cap nut simultaneously and prevent screw rollback, it is ensured that lead screw is stretched Go out the outside of chuck 23, to facilitate operator to wear pad or other elements in lead screw, and facilitate the screw pair of operator Hole operation, when these operations have been completed, operator just can press activate switch, and motor 31 will continue through gear 33 and drive tooth bar The slip of 34, electric screwdriver bar 21 also begins to again rotate and lock in lockhole by screw, when tooth bar 34 slides into the second photoswitch The position of 38, and when making light barrier 43 keep off in the fluting of the second photoswitch, leave the motor off, at this moment chuck 23 return back to Actuator base, electric screwdriver bar 21 stretches out the outside of chuck 23 the most to greatest extent, it is possible to reach lockhole interior to realize deep hole lock pair, when Torsion signal can be sent when electric screwdriver 11 reaches torsion, control electric screwdriver 11 and stop operating, control motor 31 and invert, make gear 33 drive Tooth bar 34 return back to the origin position of the first photoswitch 37, and release stay cord 26 completely, is discharged by the elastic force of spring 19, pushes away Dynamic chuck 23 parts forward extend out and reset to mechanism foremost, and make the porch of inclined tube 22 concede the cutter head portion of electric screwdriver bar 21 Point, when making feeding, screw is not blocked by electric screwdriver bar 21, and at this moment feeding machine utilizes pressure-air by next screw by inclined tube 22 Sending into the inside of chuck 23, motor starts again above action, when starting the most again screw after operator's activate switch Lock pay course of action, go round and begin again, till operator stops operation.

Last it should be noted that, above example is only in order to illustrate the technical solution of the utility model, rather than to this reality With the restriction of novel protected scope, although having made to explain to this utility model with reference to preferred embodiment, this area general Logical it will be appreciated by the skilled person that the technical solution of the utility model can be modified or equivalent, without deviating from this The spirit and scope of utility model technical scheme.
