Below in conjunction with accompanying drawing, the specific embodiment that multifunctional nut of the present utility model is criticized is described in detail.
Multifunctional nut of the present utility model is criticized, it comprises a taper shank 7, taper shank 7 middle parts are provided with a through hole 21, on the circumferencial direction of taper shank 7, evenly be provided with the hole 33 that stores six kinds of different screwdrivers 6, each hole 33 with taper shank 7 vertical in the radial direction, be provided with a relative groove 25, the two relative protruding wings 11 on the afterbody of each screwdriver 6 can slide in this groove 25.One end of through hole 21 fixedly mounts a screwdriver supporting base 4, and these screwdriver supporting base 4 front ends are hollow, and the rear end is solid.The rear end is fixed in the through hole 21 of taper shank 7, and front end is provided with two sections screw threads (18,19), and screw thread 19 cooperates with fixed spiro 5, and screw thread 18 cooperates with hexagonal lock nut 2.The front end of screwdriver supporting base 4 evenly has four grooves, relative groove 24 broads wherein, and another relative groove 23 is narrower.The groove 24 of two broads can match with the two protruding wings 11 of screwdriver 6 afterbodys.The front end that has four grooves (23,24) is used for installing and clamping screwdriver 6 afterbodys.Be equipped with one and survey electric installation in through hole 21, this survey electric installation comprises resistance 8, neon bulb 9, spring 10 and screw 12.Screw thread 22 on screw 12 and the taper shank 7 on the through hole 21 matches, and bonnet 13 is fixed on the rear end of taper shank 7.In the middle of the bonnet 13 shoulder hole is arranged, along evenly being provided with six small convex pillars on its circumferencial direction, corresponding with six holes 33 on the taper shank 7 respectively.Tightening cover 1 is rotatably fixed on the screwdriver supporting base 4 suit one bearing sleeve 3 rotationally between tightening cover 1 and taper shank 7 with fixed spiro 5.Be provided with the sleeve 27 of a hex hole 26 inwards along the center line of tightening cover 1, the end of sleeve 27 has a circular hole 29, and its aperture is less than the external diameter of fixed spiro 5.Fixed spiro 5 external diameters are fixed on tightening cover 1 on the screwdriver supporting base 4 so that make it can enter hex hole 26 less than the inscribed circle diameter of hex hole 26.Hexagonal lock nut 2 is contained in the hexagon ring 26 of tightening cover 1 slidably, and cooperates with screwdriver supporting base 4 front end screw threads 18.The hexagonal lock nut is provided with a unthreaded hole 15 and a screwed hole 16.Unthreaded hole 15 diameters also are slightly less than the external diameter of screwdriver supporting base 4 front end unthreaded portions less than screwed hole 16 diameters.Be provided with chamfering at unthreaded hole 15 and screwed hole 16 junctions.Screwdriver supporting base 4 front ends also are provided with chamfering.Be equipped with a hole 28,32 on the circumferencial direction of tightening cover 1 and bearing sleeve 3, the center in the hole 33 on the center in this hole 28,32 and taper shank 7 circumferencial directions is corresponding, gets screwdriver 6 with civilian dress.
In addition, between bearing sleeve 3 and tightening cover 1 and taper shank 7, establish a little ball 34,35.Be provided with a bigger round pool 20 on the outer connection periphery of taper shank 7, little ball 35 more than half parts are put into this round pool 20.In bearing sleeve 3, connect on the periphery and evenly be provided with six less round pools 31.Little ball 35 smaller part partly are in this round pool 31.When bearing sleeve 3 when taper shank 7 rotates, as between one in little ball 35 round pools 20 and six round pools 31 time, just show to align with a certain screwdriver 6 in the taper shank 7 in the hole on the bearing sleeve 3, this screwdriver 6 just can pass this hole 32 and take out.Be provided with a bigger round pool 30 on the outer connection periphery of bearing sleeve 3, little ball 34 more than half parts are put into this round pool 30.On the interior connection periphery of tightening cover 1, evenly be provided with a less round pool 36.When tightening cover 1 hole 28 when aliging with the hole 32 on the bearing sleeve 3, little ball 34 just is between round pool 30 and the round pool 36.
During use, first rotating support sleeve 3 when the little ball 35 in the round pool 20 on the outer connection periphery that is contained in taper shank 7 falls into roundlet hole 31 on the carrying cylinder 3, will be heard or be felt.At this moment, show that a certain screwdriver 6 faces the hole 32 on the bearing sleeve 3.Rotation lock lid 1 makes little ball 34 fall into the round pool 36 that connects in the tightening cover 1 on the periphery then.Like this, this screwdriver 6 just can pass hole 32 on the bearing sleeve 3 and the hole 28 on the tightening cover 1 is removed.After taking out required screwdriver 6, the afterbody that will have the two symmetrical protruding wings 11 inserts on the screwdriver supporting base 4.The two protruding wings 11 slide in two grooves 24.Screwdriver 6 can only slide and can not rotate relative to the screwdriver supporting base this moment.Clockwise rotate tightening cover 1, the hexagonal lock nut 2 that is contained in the hex hole 26 of tightening cover 1 also rotates with tightening cover 1.Because hexagonal lock nut 2 cooperates with the front end screw thread 18 of screwdriver supporting base 4.Therefore when hexagonal lock nut 2 rotated with tightening cover 1, also relative tightening cover 1 axially moved inwards along it.When the chamfering in the hexagonal lock nut 2 matches with screwdriver supporting base 4 Leading end chamfers, be rotated further tightening cover 1, hexagonal lock nut 2 just forces the front end of supporting base 4 to shrink inwards.Thereby tightly the afterbody of screwdriver 6 is clamped.As after using, need screwdriver 6 is put back in the taper shank 7, only needing as stated above, reverse operating gets final product.
