Abstract
The invention relates to a three section type ratchet spanner with two clamping elements each provided with an accommodation space which is for the arrangement of a boss at the second end of the other clamping element and forms a staggered state to shorten the distance between two bosses. Therefore a toggle element in a reversing switch just needs to turn a small angle to drive a clamping element to be separated from a ratchet driving element, and the shape of the toggle element can greatly reduce the area of the reversing switch and relatively increase wall thickness of the throat of the spanner body. Moreover, the invention has good appearance and is a design with industrial applicability and advancement.
Description
Technical field
The present invention relates to a kind of ratchet spanner, particularly a kind of three section type ratchet spanner.
Background technology
Along with development of science and technology and progress, people to the requirement of things also from the old thinking of " can with all right ", suitable exquisiteness and requirement become, have the conception of continuous progress or innovation only, produce new form to improve the surcharge of product, and effectively reduce cost, could under the test of Market competition, survive.
With reference to No. 519023 " improvement of spanner structure " patent of TW Announcement Number, two direction pieces of this spanner are arranged in the gathering sill of spanner handle, the guide sliding part that this two directions piece end face is protruded out wears the protruding portion that places restrictions on that is exposed to the direction control flume, this direction control piece that is hubbed in the direction control flume is provided with a guide groove, this guide groove is installed with for the guide sliding part of two direction pieces, and utilizes this guide groove to control the slip of two direction pieces.Because the guide sliding part of this two directions piece is not crisscross arranged, and make the distance between this two guide sliding part bigger, so the guide groove of this direction control piece also need be established greatlyyer, can be ccontaining for this two guide sliding part, so increased the area of direction control piece relatively, not only cut down the wall thickness of spanner handle throat, and not attractive in appearance.And the installing complex structure of this direction control piece has significantly increased the time of processing, assembling, and has improved the cost expenditure that produces, and is not handy, practical.The disadvantages that above-mentioned existing spanner structure is derived has in fact and is researched and developed the necessity that improves.
Therefore, the present invention's problem of wanting to get rid of or alleviating prior art at least and met with.
Summary of the invention
The purpose of three section type ratchet spanner of the present invention is to overcome the deficiencies in the prior art and defective, the technical problem that its desire solves is that the guide sliding part of two direction pieces of existing spanner is not crisscross arranged, and make the distance between this two guide sliding part bigger, so the guide groove of this direction control piece also need be established greatlyyer, can be ccontaining for this two guide sliding part, so increased the area of direction control piece relatively, not only cut down the wall thickness of spanner handle throat, and it is not attractive in appearance, and the installing complex structure of this direction control piece, significantly increased processing, the time of assembling, and improved the cost expenditure that produces, not handy, practical.
For reaching above-mentioned purpose, the invention provides a kind of three section type ratchet spanner, it comprises: a wrench body, the one end is a head, end is shank in addition, and its head is provided with one first holding part, and is provided with one second holding part and the 3rd tangent holding part of one and second holding part in the throat of wrench body; One spine move part, its outer rim is equipped with tooth, and this spine move part is hubbed at first holding part of wrench body in rotating mode; Two clamping pieces, it includes first end and second end, and first end of this two clamping piece is provided with tooth, and second end of this two clamping piece is provided with a projection, the projection of this two clamping piece is crisscross arranged in second holding part of wrench body, and is provided with an elastomer between this two clamping piece; One reversing switch, it is located in the 3rd holding part of wrench body rotationally, and this reversing switch is provided with one can supply the ccontaining hole of shifting part one end, and the end in addition of this shifting part is positioned between two projectioies of clamping piece, and the projection of optionally stirring the one clamping piece, with this clamping piece slippage of interlock.
Because two clamping pieces of the present invention all are provided with an accommodation space, this accommodation space can form staggered for the projection setting of another clamping piece second end, make the distance between this two projection shorter, so this is located at shifting part in the reversing switch and only need rotates a less angle and can be located away from the spine move part by interlock one clamping piece, and the kenel of this shifting part can significantly be dwindled the area of reversing switch, increased the wall thickness of wrench body throat relatively, and quite attractive in appearance, in fact be one to have the design of industry applications and progressive.
