Accompanying drawing is the utility model structural representation

The specific embodiment

By accompanying drawing as can be known, the utility model is installed in electric screw driver or pneumatic screw driver working end, support body is dismountable " L " type, and the perpendicular arm A of " L " type is a screwdriver work entrance point, transverse arm B is that screw is pushed the operation end automatically, perpendicular arm A and transverse arm B intersection are that come off sleeve pipe and screw of screw exports, wherein:

The perpendicular arm A telescoping structure that to be fixed arm 10 is connected by left-hand thread with lever arm 6, and lever arm 6 vertically slip fixed arm 10 in erect in the arm A and also are provided with accessory;

For placing the screw box of screw 3, be provided with nut fixed groove 15 and screw rod support rail 23 in the screw box in the transverse arm B, transverse arm B outer end is provided with one and annotates plug formula screw box slide lid 20, and slide lid 20 the inners are provided with and promote the slurcam 16 that screw 3 moves;

The outlet of described screw is arranged on screw and comes off under the sleeve pipe 5, and the screw outlet forms taper mouth that falls by the elasticity three tongue mouths 2 that are fixed on outlet.

Accessory in the perpendicular arm A described in the utility model comprises sheath 8, moment of torsion adjustment ring 11, screwdriver retainer ring 12, screwdriver 14 and lifting spring 13.Described fixed arm 10 tops are provided with retainer ring 7, and retainer ring 7 is provided with set bolt 9.Nut fixed groove 15 and screw rod support rail 23 in the described screw box all are provided with at least two, and spacing can be according to screw 3 models adjustment size, and screw box comes off with screw, and 5 of sleeve pipes are provided with and the corresponding screw inlet pipe mouths 4 of screw 3 sizes.Be provided with in the described screw box slide lid 20 and promote spring 21, the outer end is provided with a screw box tail-hood 22.Its outer wall 17 of described screw box is provided with elastic sheet switch 19, and elastic sheet switch 19 is fixed on the outer wall 17 by set bolt 18, and outer wall 17 is connected with perpendicular arm A by screw box stator 24 and gim peg 25.Described elasticity three tongue mouths 2 are made up of the shell fragment of three tongue shapes, and adjustable being arranged on the fixing hole 1 forms bell.

Structural principle of the present utility model:

Fixed arm 10 of the present utility model and lever arm 6 are two pitch circle cartridge types, as shown in the figure, fixed arm 10 and lever arm 6 all are columnar, Shi Rangqi is fixing can only vertically to prevent lateral deviation when lever arm 6 slides up and down 10 li of fixed arms, and a left-hand thread arranged below fixed arm 10, also there is a left-hand thread top of lever arm 6, can prevent that lever arm from splitting away off, thereby has guaranteed that lever arm 6 slides up and down in 10 li effective linear patterns of fixed arm.

What the utility model screw box adopted is multifunction structure, that is: the nut of every in screw box fixed groove 15 is screws of placing a model, 15 screws for three kinds of different models of placement of three nut fixed grooves; Screw length differs and spiral shell root support rail 23 spacings of screw box the inside can be improved when not being very big if use when needing, and just can put the more screw of polytypic, the effective like this space that utilized, and it is more reasonable to design.

The utility model screw sleeve pipe that comes off, as shown in the figure, what adopt too is multifunction structure, that is: three screw inlet pipe mouths 4 that can supply three kinds of different models are arranged in screw comes off sleeve pipe 5, certainly screw come off sleeve pipe 5 must and screw box be supporting use, follow screw box the same; Screw inlet pipe mouth 4 spacings that screw differs 5 li of the sleeve pipes of screw can being come off when not being very big if use to need the time spent are adjusted, just can be at the come off screws of 5 li more models of use of sleeve pipe of same screw; Otherwise identical, make come off sleeve pipe 5 of screw realize many usefulnessization like this, design and more become reasonable.

The outlet of the utility model screw is elasticity three tongue mouths, as shown in the figure, elasticity three tongue mouths 2 are that the screw after screw box comes off can directly erect elasticity three tongue mouths 2, because being fixed on elasticity three tongue fixing holes 1 by the shell fragment of three tongue shapes, elasticity three tongue mouths 2 form bell, and his bore can only allow screw the silk root half drop out and nut and half silk root still can erect in the centre, so can directly not drop out.Elasticity three tongue mouths 2 can be regulated according to screw model size, according to the object deformation principle in the physics, the deformation that takes place when the big more object of the pressure that object is subjected to is just big more, so up to electric screw driver to its rotation and there is downward thrust just can make change greatly and slowly the distending elasticity three tongue mouths of screw along with silking, till screw all is screwed in the object, thereby guaranteed that screw is vertically to fall down, prevented from after coming off, directly to drop out with lateral deviation screwdriver can not normally be rotated with screw.

Embodiment described in the utility model only is the description that preferred implementation of the present utility model is carried out; be not that the utility model design and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
