Description
Technical field
The present invention relates generally to a kind of open-end wrench, particularly a kind of open-end wrench with ratcheting function.
Background technology
Please refer to Figure 26, is a kind of schematic diagram of the reciprocating type opening wrench with anti-fall function, and open-end wrench comprises a shank, a head, an anti-falling piece and an elastic component.This shank grips for user, this shank at least one end is provided with this head, this head has one first jaw, one second jaw and extends the extension between this two jaws bottom, and structure is enclosed in these two jaws and this extension a driving space, accommodating in it for a hexagonal (hexagon)nut.This driving space has an opening away from this extension, this first jaw has the surface of revolution and the one first jaw tip of first support surface near extension, a recess, the junction of this Yu Gai extension, the first support surface forms one and supports angle, this is supported angle preferably and is 120 degree angles, a corner for this hexagonal (hexagon)nut is accommodating, this extension also has an extreme lower position, for another corner of this hexagonal (hexagon)nut against.This first jaw tip comprises a pair of support arm, and this is to forming a profile groove between support arm, and this profile groove bottom surface is an abutment face, and this first jaw tip more offers an appearance hole.Moreover, this surface of revolution is between this first support surface and the first jaw tip, and this surface of revolution preferably is a cancave cambered surface, wherein this first jaw tip has more a short plane towards the second support surface, this second jaw has one second support surface, the level interval of this first, second support surface is s, the level interval of this short plane and the second support surface is not less than s, and the maximum horizontal spacing preferably of this surface of revolution distance the second support surface should be not less than 1.16s, wherein this hexagonal (hexagon)nut the length of side is slightly less than to s.
Obvious, the head of aforementioned open-end wrench must offer profile groove and hold hole in order to install anti-falling piece and elastic component, offering of profile groove makes the first jaw form two support arms, the forming mode of profile groove easily allows two support arms have the risk of fracture, and the diapire of profile groove is located at again in appearance hole, because the width of the first jaw is limited, the degree of depth of therefore holding hole almost penetrates the first jaw.Because profile groove makes the structural strength of the head of open-end wrench weaken with holding the design in hole, but the head of open-end wrench be because need to bear pull force, and need to there is preferably structural strength, therefore aforesaid design, have the disappearance of structural strength deficiency, and need to be improved.
With reference to Figure 27, it is the schematic diagram of another kind of open-end wrench structure.Open-end wrench is by shank part, opened wrench head and live splint jaw unit form, wherein opened wrench head is provided with connected opening and dodges portion, end face is down sequentially formed with a depression and a groove chamber dodging in institute of portion confining spectrum, depression and groove chamber all directly penetrate out in a side adjacent with the portion of dodging, and this depression end face is arranged with lockhole and pivot hole, live splint jaw unit respectively has a folder jaw piece, one elastic parts and a capping, this folder jaw piece utilizes one end to extend top, the axostylus axostyle of bottom surface is inserted in pivot hole, and energy pivot group is in groove chamber, and make the other end on its tool inclined-plane pass from the hollow part of groove chamber, elastic parts is arranged between folder jaw piece and groove chamber, the profile of capping coordinates depression setting, it has perforation and spacing hole, capping utilizes perforation provide screw to pass and lock in lockhole, spacing hole provides axostylus axostyle to insert, it can not only be installed in depression, more can be used for groove chamber end face to seal.
This open-end wrench is inserted in the axostylus axostyle of folder jaw piece in the counterbore of opened wrench head, and the inclined-plane of folder jaw piece is subject to the pushing tow of elastic parts and supports and be located at screw.When open-end wrench uses, folder jaw piece can rotate taking axostylus axostyle and counterbore as fulcrum, in other words, folder jaw piece and axostylus axostyle are because be the factor of one, in the time of spindle rotation, the strength of rotation is passed to folder jaw piece by axostylus axostyle and bears, and such design can allow folder jaw piece easily bear twisting resistance for a long time and damage.And while pressing from both sides jaw piece only taking axostylus axostyle as fulcrum, folder jaw piece promotes the strength meeting deficiency of screw, and promotion screw that cannot be firm.In addition, folder jaw piece is face with screw and contacts and can allow folder jaw piece and screw formation skid, and cannot obtain preferably snap-in force.
Because the disappearance of above-mentioned existing structure, the inventor invents a kind of open-end wrench with ratcheting function, and it can overcome all shortcomings of above-mentioned existing structure.
