The specific embodiment
See also Fig. 1 to Fig. 3, be the selected example structure of the present invention shown in the figure.
The present invention is a kind of Wrench head pivoting and positioning structure, comprising:
One wrench body 1, the one end has a connection unit 11, this connection unit 11 has a groove 12 at middle position towards this wrench body 1 other extreme direction, these groove 12 both sides have a protuberance 13 respectively, and this groove 12 has a bottom surface 14, and this bottom surface 14 is provided with a hole 141, and this hole 141 is appropriate locations that are communicated to this body 1, and forming a communication channel 15, this two protuberance 13 has parallel this groove 12 bottom surfaces 14 and the perforation on concentric 132 respectively.This connection unit 11 has provided an opening 16 in these wrench body 1 contiguous these groove 12 bottoms 14, and this opening 16 is connected with above-mentioned communication channel 15.
One location device 2, form by a driving link 21 and a driven member 22, in the present embodiment, this driving link 21 is a nut, and this driven member 22 is a screw rod, this driving link 21 is the openings 16 that are installed in this wrench body 1, and this driven member 22 is to be stretched through by these connection unit 11 set holes 141, and combines and enter in the communication channel 15 of this wrench body 1 with this driving link 21.
One work head 3, it is to combine with the groove 12 of above-mentioned connection unit 11 that the one side has a protuberance 3, and this protuberance 31 have one with the protuberance 13 set perforation 132 corresponding through holes 32 of this wrench body 1 connection unit 11,31 pairs of this protuberances should have a sheathing section 33 in outer rim by positioner 2 driven members 22 1 ends.In the present embodiment, this sheathing section 33 is to be formed by connecting by a plurality of planes 34.
When this work head 3 was engaged in this connection unit 11, two protuberances, 13 perforations 132 of this connection unit 11 were corresponding mutually with the through hole of these work head 3 protuberances 31 32, insert for a fixation kit 35.In the present embodiment, this fixation kit 35 is a latch.
The user is when use is of the present invention, see also Fig. 4, when desire is adjusted this work head 3 it is pivoted, because having an appropriate depth, the hole 141 in this wrench body 1 and this communication channel 15 wear for this driven member 22, this driving link 21 is to combine with this driven member 22.Therefore, rotatable this driving link 21 make this driven member 22 be slidedly arranged on 15 of hole 141 in this wrench body 1 and this communication channels, and contact to the sheathing section 33 of this work head 3 this work head 3 can be pivoted easily.When if this work head 3 is adjusted to required use angle, then can rotate this driving link 21 once more, this driven member 22 is advanced towards these work head 3 directions, and then make 22 pairs of this driven members should working head portion these work head 3 sheathing sections 33 of 3 sheathing sections, 33 1 end contacts, make this work head 3 in required angle orientation.
In sum, this spanner work head pivoting and positioning structure is owing to adjust this driven member directly against this work head 3 by this driving link, steel ball than prior art is next against more firm by the elastic force of spring itself, and do not have steel ball when the application of force is big, have and break away from and can't be positioned the phenomenon of required angle.
The second embodiment of the present invention, as shown in Figure 5, its structure is and the first embodiment compatibility, does not repeat them here.What they were different is, the sheathing section 42 of these work head 4 protuberances 41 is a profile of tooth section, and to driven member 43 outer rims that should working head portion 4 protuberances 41, also is provided with a toothed region 44.Be involutory by the tooth of these work head 4 protuberances 41 sheathing sections 42 and the toothed region 44 of this driven member 43, and can more closely fix this work head 4.
See also Fig. 6, the two ends of this wrench body 1 all can be provided with above-mentioned Wrench head pivoting and positioning structure, and indefinite only has an end setting, and this work head 5 is also variable is changed to multi-form work head.In the present embodiment, this work head 5 is a ratchet spanner.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
In sum, the present invention is on structural design, use practicality and cost benefit, it is required to meet industry development fully, and the structure that is disclosed also is to have unprecedented innovation structure, have novelty, creativeness, practicality, the regulation that meets relevant novel patent requirement is so mention application in accordance with the law.
