The specific embodiment
Below in conjunction with accompanying drawing, do more detailed explanation with other technical characterictic and advantage to the present invention is above-mentioned.
With reference to Fig. 1 and Fig. 2, the instrument extension bar of tool d-axis of the present invention and universal function includes a body 10, one and turns to extension bar 20, socket tube 30, a coupling unit 40 and a C type clasp 70; Wherein:
Please cooperate simultaneously with reference to Fig. 3, body 10 1 ends form a shaft 11, and shaft 11 can be accepted rotary power and make body 10 produce spinning movement.Body 10 is provided with a lever 111 at shaft 11 ends, and lever 111 is the power when supplying the user to grip and can accept the user to rotate and make body 10 produce spinning movements.
Turn to extension bar 20 to be connected in body 10, and turn to extension bar 20 between obliquity or coaxial position, to move with respect to body 10.Turn to extension bar 20 to have a drive end 21, establish the screwdriver head that an engagement groove 211 can be accepted different shape in the drive end 21.Drive end 21 also is provided with a magnet 212 at engagement groove 211 blind ends, and magnet 212 is in order to magnetic absorption screwdriver head.
The head 41 of coupling unit 40 is made as the cross section of non-circular shape and has the surface 43 of at least one arc surfaced or the surface 43 that at least one is plane; The surface 43 of head 41 can be corresponding on the surface 32 of perforate 31, and make body 10 with turning to extension bar 20 to rotate.The head of coupling unit 40 is made as hexagon in the present embodiment.The neck 42 of coupling unit 40 can increase the angle of inclination that turns between extension bar 20 and the body 10.
The head 41 of coupling unit 40 has one first diameter D1, and the first diameter D1 typically refers to the maximum gauge of head 41.The head 41 of coupling unit 40 is adjacent to neck 42 and has one second diameter D2, and the second diameter D2 is less than the first diameter D1.
Turn to extension bar 20 also to be provided with a shoulder 23, the neck 42 that shoulder 23 is connected in coupling unit 40 is away from an end of head 41, and shoulder 23 has the outside of circular cross-section.Turn to the shoulder 23 of extension bar 20 to have one the 3rd diameter D3, the 3rd diameter D3 is greater than the second diameter D2, and the 3rd diameter D3 is less than the first diameter D1.
The internal diameter of C type clasp 70 under nature is greater than the second diameter D2 of coupling unit 40 heads 41; And the internal diameter of C type clasp 70 under nature is less than the first diameter D1 of coupling unit 40 heads 41, so C type clasp 70 can be clamped in the outside of head 41.Because the internal diameter of stopper slot 33 and two diameter difference of coupling unit 40 heads 41 first diameter D1 are less than two diameter difference of C type clasp 70 external diameters and C type clasp 70 internal diameters; So when C type clasp 70 is clamped in the first diameter D1 and the outside between the second diameter D2 of head 41; The external diameter of C type clasp 70 can limited groove 33 the internal diameter restriction and make the first diameter D1 of head 41 can't be through the internal diameter of C type clasp 70; Like Fig. 6 and Fig. 7,, C type clasp 70 deviates from perforate 31 so can preventing the head 41 of coupling unit 40.
In the present embodiment; C type clasp 70 includes two free end pin 71 and one and is connected two blocking parts 72 between the free end pin 71; The radius of two free end pin 71 is less than the radius of blocking part 72, makes two free end pin 71 contract in more than blocking part 72, so; Two free end pin 71 can be clamped in the outside of shoulder 23, and blocking part 72 can be limited in C type clasp 70 in the stopper slot 33.
With reference to Fig. 3 and Fig. 4, expression turns to extension bar 20 to remain on the state of coaxial position with respect to body 10.C type clasp 70 is to be clamped in shoulder 23 outsides that turn to extension bar 20, not only make to turn to extension bar 20 and body 10 to remain on coaxial position, and C type clasp 70 has more the effect that firm clamping turns to extension bar 20, reaches the good state that grips.
With reference to Fig. 5, expression turns to the shoulder 23 of extension bar 20 to break away from the state that C type clasp 70 grips.When turning to extension bar 20 to be away from body 10 to move, shoulder 23 breaks away from the clamping of C type clasps 70 and loses the effect that grips of C type clasp 70.
With reference to Fig. 6 and Fig. 7, expression C type clasp 70 prevents that the head 41 of coupling unit 40 from deviating from the state of perforate 31.When turning to extension bar 20 to continue to be away from body 10 to move; The head 41 of coupling unit 41 receives the block of C type clasp 70; By seeing obviously among the figure that C type clasp 70 blocks are when the outside of head 41; The external diameter of C type clasp 70 can limited groove 33 the internal diameter restriction and make the first diameter D1 of head 41 can't be through the internal diameter of C type clasp 70, reach and make C type clasp 70 prevent that the head 41 of coupling unit 40 from deviating from the effect of perforate 31.
With reference to Fig. 8 and Fig. 9, expression turns to extension bar 20 to remain on the state of obliquity with respect to body 10.C type clasp 70 can prevent that the head 41 of coupling unit 40 from deviating from perforate 31; And the head 41 of coupling unit 40 can make and turns to extension bar 20 to favour body 10; Driving when making body 10 rotations turns to extension bar 20 and then to rotate; And maintaining an angle when rotating, the neck 42 of coupling unit 40 can increase the angle of inclination that turns between extension bar 20 and the body 10.
With reference to Figure 10 and Figure 11, be second embodiment of the present invention.Present embodiment and aforementioned first embodiment are roughly the same, and its difference is in body 10A one end and forms a drive end 12, and turns to the end of extension bar 20A to form a shaft 22.Drive end 12 has an engagement groove 121 and is located at the magnet 122 of engagement groove 121 blind ends.The end of shaft 22 is provided with a lever 221.
With reference to Figure 12 and Figure 13, be the 3rd embodiment of the present invention.Present embodiment and aforementioned first embodiment are roughly the same; Its difference is in the shoulder that turns to extension bar 20 23 and is equipped with a catching groove 231; Catching groove 231 has one the 4th diameter D4, and the 4th diameter D4 is greater than the second diameter D2, and the 4th diameter D4 is less than the 3rd diameter D3.
The internal diameter of C type clasp 70 under nature is less than the 3rd diameter D3 that turns to extension bar 20 shoulders 23; So C type clasp 70 can optionally be combined in the catching groove 231 of shoulder 23; When C type clasp 70 is combined in the catching groove 231 of shoulder 23; The external diameter of C type clasp 70 is not more than the internal diameter of stopper slot 33, so turns to extension bar 20 can be clamped to the position coaxial with body 10 by C type clasp 70 equally.
More than explanation is just illustrative for the purpose of the present invention, and nonrestrictive, those of ordinary skills understand; Under the situation of spirit that does not break away from following accompanying claims and limited and scope, can make many modifications, change; Or equivalence, but all will fall in protection scope of the present invention.
