The specific embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Consult Fig. 1 and Fig. 2, the preferred embodiment of the utility model ratchet spanner comprises a body 2, tool heads 3, two clamping devices 4, two elastic components 5, block piece 6, operating parts 7, a lid 8, and a spiro connecting unit 9.
This body 2 comprises a holding section 21 and an active section 22 of adjacent setting.This active section 22 have a storage tank 221, basal wall 222, one be connected in the outer peripheral edges of this basal wall 222 and with this basal wall 222 jointly around defining the surrounding wall 223 of this storage tank 221, two pivot connected slots 224 that are positioned at this surrounding wall 223 and are communicated with this storage tank 221, an and axis hole 225 that is positioned at this basal wall 222.
This tool heads 3 comprises a middle shaft part that can be arranged at rotationally this storage tank 221 31, a ratchet part 32 arranging around this middle shaft part 31, and an operate portions 33 that extend in the outside towards this storage tank 221 from this middle shaft part 31.In the present embodiment, this operate portions 33, for the adapter of machining tool can be installed, still, in other enforcement aspect, also can directly just be made into specific machining tool.
Described clamping device 4 can swingingly be arranged in this storage tank 221, and has separately one to tooth engaged portion 41 that should ratchet part 32, and contrary this tooth engaged portion 41 arranges and be articulated in the shaft 42 of corresponding pivot connected slot 224.
Described elastic component 5 is arranged at described tooth engaged portion 41 away from a side of this ratchet part 32 and permanently pushes against described tooth engaged portion 41 contiguous these ratchet parts 32 with elastic force.In the present embodiment, described elastic component 5 is spring.
This block piece 6 comprises an installation portion 61 that can be sheathed on rotationally this operate portions 33, and one connects this installation portion 61 and is positioned at these ratchet part 32 outsides and is positioned at the stopper 62 between described tooth engaged portion 41.
What this operating parts 7 comprised a pushing and pressing part that can be positioned at rotationally 41, described tooth engaged portion 71, this pushing and pressing part 71 of interlock pushes away shank 72, and one connects this pushing and pressing part 71 and this connecting rod portion 73 that pushes away shank 72 and be hubbed at the axis hole 225 of this active section 22.
This pushing and pressing part 71 has a first end 711 that connects this connecting rod portion 73, and second end 712 that extends and extend towards described clamping device 4 expansions towards the direction away from this ratchet part 32 from this first end 711.
This lid 8 can unload a liftoff side that is covered on these surrounding wall 223 contrary these basal walls 222, and comprises the working hole 81 that this operate portions 33 of a confession wears.
This spiro connecting unit 9 comprises that two screw rod parts 91, two are arranged at the perforation 92 that this basal wall 222 wears for described screw rod part 91, and two are arranged at the screw 93 that this lid 8 is spirally connected for described screw rod part 91.Be noted that in other enforcement aspect, described perforation 92 can be to be also arranged at this lid 8 to wear for described screw rod part 91, and described screw 93 can be to be also arranged at this basal wall 222 to be spirally connected for described screw rod part 91.
Consult Fig. 2,3,4, when use, this pushes away shank 72 and can drive this pushing and pressing part 71 to rotate between a primary importance, a second place and the 3rd position.
(see figure 2) in the time of this primary importance, described tooth engaged portion 41 is subject to the pushing and pressing of described elastic component 5 and contiguous this ratchet part 32, and be butted on this stopper 62 simultaneously, in the time that this tool heads 3 operates, this ratchet part 32 can be subject to respectively the blocking of described tooth engaged portion 41 and this tool heads 3 cannot be rotated relative to this body 2 in the time of different direction rotations, and then person easy to use operates spanner, and due to described tooth engaged portion this ratchet part 32 of 41 interlocks completely closely now, therefore when operating while making this pushing and pressing part 71 leave this primary importance, this pushing and pressing part 71 can be rotated easily because of the gap between described tooth engaged portion 41 and this ratchet part 32.
(see figure 3) in the time of this second place, the tooth engaged portion 41 that the second end 712 of this pushing and pressing part 71 can push against below in figure is away from this ratchet part 32, now this ratchet part 32 can be subject to the blocking of the tooth engaged portion 41 of top in figure in the time rotating clockwise, and this tool heads 3 cannot be rotated relative to this body 2 along clockwise direction, and this ratchet part 32 is while rotating in the counterclockwise direction, owing to not being subject to the blocking of the tooth engaged portion 41 of below in figure, therefore in figure, the tooth engaged portion 41 of top can be in the rotation process of this tool heads 3 be sequentially promoted by the elastic component 5 above in this ratchet part 32 and figure, and this tool heads 3 can be rotated in counterclockwise smoothly, only need the demand of single rotation direction to meet user.
Consult Fig. 1,4, (see figure 4) in the time of the 3rd position, the tooth engaged portion 41 that the second end 712 of this pushing and pressing part 71 can push against top in figure is away from this ratchet part 32, due to the second place be opposite action, therefore, now this tool heads 3 just can be rotated relative to this body 2 in clockwise direction smoothly, and cannot be in counterclockwise rotating relative to this body 2, and meeting equally user only needs the demand of single rotation direction.
It is worth mentioning that, in other enforcement aspect, this block piece 6 can be also directly to combine with this lid 8, and does not need to be sheathed on this operate portions 33, also can reach identical effect.
In sum, by the setting of this block piece 6, this pushing and pressing part 71 is in the time of this primary importance, not this ratchet part 32 of interlock completely closely of described tooth engaged portion 41, and this pushing and pressing part 71 can not be stuck, and then can conveniently turn to other positions, compared to existing ratchet spanner, the utility model does not have the problem that cannot switch this pushing and pressing part 71, and this spanner of energy convenient operation, so really can reach the purpose of this utility model.
