The specific embodiment
The present invention is the commutating structure of relevant a kind of Wrench, see also Fig. 1, shown in Figure 2, present embodiment is to be example with D spanner, but do not limit with this, its body 1 is that a ratchet head 10 is set, these ratchet head 10 central authorities offer a circular driver slot 20, this driver slot 20 is to be the two sides to open aspect, this ratchet head 10 is provided with an embedded chute 30 below driver slot 20, this embedded chute 30 is slightly to become the U type, and embedded chute 30 is communicated with driver slot 20, and this ratchet head 10 then laterally is provided with a nearly oval-shaped elongated slot 40 below embedded chute 30, this elongated slot 40 is communicated with embedded chute 30, wherein:
Be provided with the ratchet portion 21 of a circle in this driver slot 20, these ratchet portion 21 1 ends are provided with a quick detach end 22, the other end then is provided with a drive end 23, pushing this quick detach end 22 can make ratchet portion 21 break away from ratchet head 10 fast, 23 of this drive ends can be used for the socket workpiece so that pull workpiece, and between this driver slot 20 and the ratchet portion 21 fixture 24 can be set, this fixture 24 is that the C type is buckled, by this fixture 24 packing ratchet portion 21 in driver slot 20;
This embedded chute 30 is provided with a clamping piece 31, form a ratchet 32 on one end face of this clamping piece 31, this ratchet 32 can mesh with ratchet portion 21 peripheries, make ratchet portion 21 and clamping piece 31 be a state that offsets, these clamping piece 31 other ends then form a recess 33 again, and this recess 33 comprises one first recess 331 and one second recess 332;
This body 1 forms a lower recessed edge 41 on elongated slot 40 surfaces, be provided with a device for regulating direction 42 in this elongated slot 40, this device for regulating direction 42 and 40 groups of elongated slots are established the position and are worn one and hold in 421. these appearance holes 421, hole positioning piece 422 is set, this keeper 422 comprises that a pearl body 4221 of replacing with clamping piece 31 and compels to support the elastomer 4222 of pearl body 4221, this device for regulating direction 42 exposes the part of elongated slot 40 again, be provided with one and can be used for transferring the plectrum 423 that body 1 is pulled direction, the area of this plectrum 423 is then less than recessed edge 41, and device for regulating direction 42 is in towards elongated slot 40 opening directions, the place, the place ahead that holds hole 421 offers a loose slot 424, then plug a stop part 425 on this loose slot 424, the upper end of this stop part 425 is to be blocked in the embedded chute 30, to prevent that device for regulating direction 42 from dropping outside elongated slot 40, when this body 1 is finished assembling, its structure as shown in Figure 2, the surface of this device for regulating direction 42 is the horizontal planes that flush in ratchet head 10;
Please refer to again shown in Fig. 3 A and Fig. 3 B, when body 1 desire is pulled clockwise, be that device for regulating direction 42 is transferred left, make keeper 422 be resisted against first recess 331,33,31 of this clamping pieces by ratchet 32 with 21 engagements of ratchet portion and fasten in the left side of ratchet portion 21, make body 1 pull clockwise, relatively, when if desire uses body 1 to pull counterclockwise, then this device for regulating direction 42 is transferred to the right, made keeper 422 be resisted against second recess 332,33,31 of this clamping pieces by ratchet 32 with 21 engagements of ratchet portion and fasten in the right side of ratchet portion 21, make body 1 as Fig. 3 B, can pull counterclockwise;
Because the plectrum 423 of device for regulating direction 42 is less than recessed edge 41, so stirring device for regulating direction 42 is turning left or right the transfer, the edge of the plectrum 423 of this device for regulating direction 42 can not exceed outside the body 1 fully, so when using body 1 to pull, the plectrum 423 of need not worrying can knock the wall at collision application of force place, cause device for regulating direction 42 to move and remove the locating effect that body 1 is pulled direction, in addition, because the design of recessed edge 41 makes device for regulating direction 42 flush in the horizontal plane of ratchet portion 21, so in the time of need not worrying that body 1 stretched into application of force place, the toggle or the driving lever on body 1 surface can take place to be convexly set in as prior art, the promotion that is subjected to edge, corner or other part causes the location structure of device for regulating direction 42 to be transferred or orientation is changed, so can ensure the convenience and the smoothness of body 1 operation;
The present invention also can be arranged on the ratchet spanner except that can be used for the above embodiments as shown in Figure 4, cooperatively interacts by the structure between recessed edge 41 and the device for regulating direction 42, reaches effect as hereinbefore.
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.The corresponding relation of device for regulating direction 42 and ratchet head 10 for example; do not trim mutually and exceed with the surface with both of the present invention; also the surface of device for regulating direction 42 can be arranged to be lower than the aspect of ratchet head 10, protect device for regulating direction 42 not knocked by collision by the difference in height of 10 pairs of tuning devices 42 of ratchet head.
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 patent of invention important document is so mention application in accordance with the law.
