Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the perspective exploded view of first embodiment of the invention
Fig. 2 is the user mode schematic diagram of first embodiment of the invention
Fig. 3 is the perspective exploded view of second embodiment of the invention

The specific embodiment
See also Fig. 1 to Fig. 2, be the selected example structure of the present invention shown in the figure.
The ratchet spanner of present embodiment, it comprises that members such as a body 1, a brake block group 2, a ratchet head 3 form.Wherein:
This body 1, it has a Yi Wo Bing portion 11 and a head 12, this head 12 offers an accommodation space 13, ccontaining for this ratchet head 3, the periphery of this ratchet head 3 has ratchet 31, and cooperate a C type clasp 32 and be combined into one, and this accommodation space 13 is provided with a breaker slot 14 near the madial wall of Gai Wo Bing portion 11, ccontaining for this brake block group 2.
Above-mentioned brake block group 2 comprises a sliding shoe 21, a brake block 22 and an elastic parts 23.This elastic parts 23 is a compression spring in the present embodiment; 21 pairs of this sliding shoes should ratchet head 3 one sides have a cambered surface 211,22 pairs of this brake block should ratchet head 3 one sides have a system tooth 221 of several dentations, and this sliding shoe 21 is respectively equipped with a holding part 212,222 with brake block 22 corresponding end faces, and each holding part 212,22 is a groove in the present embodiment; And these elastic parts 23 2 ends are respectively equipped with a location division 231, the location division 231 of this elastic parts 23 is a locating ring, for in each groove that penetrates this sliding shoe 21 and this brake block 22 respectively and be connected, with engagement, to drive this ratchet head 3 by brake block 22 system teeth 221 and ratchet head 3 ratchets 31.
During assembling, be that locating ring with these elastic parts 23 2 ends is inserted in respectively in each groove of this sliding shoe 21 and this brake block 22 to form this brake block group 2, again this brake block group 2 is packed in the breaker slot 14, make the system tooth 221 of the ratchet 31 aligning brake block 22 of these ratchet head 3 peripheries, and this C type clasp 32 of packing into promptly finishes assembling, and form can unidirectional rotation ratchet spanner the system toothing.
Owing to, the sliding shoe 21 and the brake block 22 of brake block group 2 all is placed in the breaker slot 14 in the above-mentioned assembling process, therefore has to assemble easily, dismantle simply and locate effect easily.
During use, as shown in Figure 2, when Gai Wo Bing portion 11 when pulling clockwise, this brake block 22 can be meshed the system tooth 221 of brake block 22 with the ratchet 31 of ratchet head 3 because of being subjected to shoring of elastic parts 23, pulls the effect that workpiece screws to reach.Otherwise, when desiring to unscrew workpiece, earlier that body is upper and lower end face exchange, again when pulling Gai Wo Bing portion 11 counterclockwise, because this brake block 22 is subjected to shoring of elastic parts 23, this brake block 22 system teeth 221 can be meshed with the ratchet 31 of ratchet head 3, reach and pull the effect that workpiece unscrews because of pulling Gai Wo Bing portion 11 counterclockwise.
And ratchet head of the present invention 3 drives and is single direction, operates more simple and has more durability; And this sliding shoe 21 is the design of cambered surface 211 corresponding to a side of ratchet head 3, therefore, and when driving pawl head 3, brake block 22 system teeth 221 are meshed with the ratchet 31 of ratchet head 3, can rotate more smoothly, for the user, and better practicality and the convenience of tool.
Certainly, still there are many examples in the present invention, therebetween the only variation on the details.See also the 3rd figure, it is the second embodiment of the present invention, and wherein this elastic parts 41 spring 411 that is the ㄇ font is inserted in respectively for two end springs 411 in each groove 421,431 of this sliding shoe 42 and this brake block 43, also be same as first embodiment, can reach good binding.
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.
