The specific embodiment
Below in conjunction with Figure of description the present invention is further specified.
Moment of torsion capable of reversing of the present invention transmits bar 02 shown in Fig. 1-2; It is that rotating shaft 1 is assemblied in the sleeve 2; The rotating switching-over seat 3 of the front end assembling of sleeve 2; Establish input gear 6 in the switching-over seat 3, transmit gear 7, output gear 8 (the diagram three is bevel gear), input gear 6 is assemblied in the front end of rotating shaft 1, output gear 8 is assemblied in and rotates on the moment of torsion output of being located on the switching-over seat 39; Transmit gear 7 between input gear 6 and output gear 8, the tail end of rotating shaft 1 is established moment of torsion and is applied structure 10.In view of this structure; Can switching-over seat 3 be rotated the switching-over that (this rotation is stepless rotation, and therefore switching-over seat 3 can rest on the interior unspecified angle of its slewing area) realized moment of torsion output 9 with respect to sleeve 2, screwdriver bit or screwdriver bit seat that moment of torsion output 9 can be screwdriver (are illustrated as the screwdriver bit seat; On the screwdriver bit seat, can settle screwdriver bit 03); Also can be the sleeve that is used to screw nut, bolt, therefore, apply structure (like square toes, turret head, key etc.) through moment of torsion and can realize screwing.
As moment of torsion capable of reversing of the present invention being transmitted further improving and replenishing of bar; The present invention also comprises following additional technical characterictic; Though Fig. 1-2 has comprised following all additional technical features; Be preferred embodiment of the present invention, but the present invention is not limited to this situation, when embodiment of the present invention, they is selected for use on the described technical scheme of epimere according to concrete effect.
At first, switching-over seat 3 is assemblied in the front end of sleeve 2 through pivot 11, realizes switching-over so that the seat that commutates pivots.For making compact conformation, transmit gear 7 and be assemblied on the pivot 11, and this structure makes that to transmit gear 11 coaxial with switching-over seat 3, when the switching-over of switching-over seat, be easy to keep transmitting the engagement transitive relation that gear mesh is imported gear to output gear.Especially, transmit gear 7 rotating being assemblied on the pivot 11, so can make pivot 11 fastening being assemblied on the switching-over seat 3, nonetheless,, then transmit gear and can assemble (as through the key assembling) with pivot is fixing as if selecting the pivot that can on the switching-over seat, rotate for use.
Secondly; The front end of sleeve 2 establish one will commutate the seat 3 the location a location latch fitting 4; Switching-over seat 3 is provided with and locatees the location division 5 that latch fitting 4 cooperates, and is through locating the cooperating this fixed-site of latch fitting 4 and location division 5, general; The location division can be more than two, so that can be at the fixing switching-over seat of plural special angle.Concrete, location division 5 is for being located at the locating hole on the switching-over seat 3, and location latch fitting 4 inserts locating hole for being assemblied in the scalable latch of sleeve 2 front ends with latch, can locating hole be withdrawed from latch from switching-over seat location, and rotatable switching-over seat commutates.Further, effect one elastic component 12 (being illustrated as the helical spring that is nested with on latch) on the latch, the elastic force of elastic component 12 makes latch insert locating hole, therefore can the switching-over seat be remained positioned in corresponding position.
The 3rd, switching-over seat 3 is made up of with second pedestal 14 first pedestal 13 of butt joint and by securing member 15 (being illustrated as tighten ring) two pedestals is assembled together, and pivot 11 and switching-over 3 a fastening assembling can guarantee the intensity of the switching-over seat of two pedestals formations.
The 4th, when moment of torsion output 9 was made up of with second pedestal first pedestal of butt joint with 3 assemblings of switching-over seat, especially switching-over seat through axial location portion provided thereon (like axle with lasso or step), such structure was convenient to assemble.
The 5th, sleeve 2 is by first cylindrical shell of butt joint and second cylindrical shell is formed and by securing member (being illustrated as tighten ring) two cylindrical shells are assembled together.
The 6th, rotating shaft 1 is through axial location portion 16 provided thereon (like axle with lasso or step) and sleeve 2 assemblings.When especially sleeve was made up of first cylindrical shell that docks and second cylindrical shell, such structure was convenient to assembling.
The 7th, the front end of sleeve 2 has a pair of ear 17, and switching-over seat 3 is assemblied in this between the ear, can keep between two ears than large space, therefore is convenient to assemble the switching-over seat of larger volume and guarantees the switching-over of switching-over seat flexibly.
Screwdriver of the present invention comprises handle 01 and batch bar; Criticizing bar is served as by moment of torsion transmission bar 02 capable of reversing of the present invention; That is: criticize the rotating shaft 1 that bar comprises sleeve 2, obtains moment of torsion from handle 01; Rotating shaft 1 is assemblied in the sleeve 2; The rotating switching-over seat 3 of the front end assembling of sleeve 2 is established input gear 6, is transmitted gear 7, output gear 8 in the switching-over seat 3, input gear 6 is assemblied in the front end of rotating shaft 1; Output gear 8 is assemblied in and rotates screwdriver bit or the screwdriver bit seat of being located on the switching-over seat 3 (being used to settle screwdriver bit) (this screwdriver bit or screwdriver bit seat transmit the moment of torsion output 9 of bar 02 corresponding to the present invention's moment of torsion capable of reversing), transmits gear 7 between input gear 6 and output gear 8.Therefore, regulate the direction of screwdriver bit during use, alignment screw; Apply moment of torsion through handle 01 countershaft 1; Then this moment of torsion passes to screwdriver bit (the perhaps screwdriver bit on the screwdriver bit seat) and screws through input gear 6, transmission gear 8, output gear 9 successively, therebetween, and sleeve 2, switching-over seat 3 inertias.
Serve as seeing that batch bar of screwdriver of the present invention transmits bar by moment of torsion capable of reversing of the present invention, therefore, the technological means that moment of torsion capable of reversing of the present invention transmits bar all can be applied directly on the screwdriver of the present invention, does not repeat them here.
Screwdriver of the present invention; Rotating shaft 1 can apply structure 10 through the moment of torsion of being located at its tail end and cooperate with handle 01 (shown in Figure 6 being so) loading and unloading; Also can fixedly be assemblied on the handle; Perhaps on handle, set to transmission mechanism, rotating shaft is assemblied in and can realizes on the directed transmission mechanism that orientation screws continuously, and screwdriver bit does not break away from that screw, hand also need not break away from repeatedly, gripping handle when screwing continuously.
