Description
Technical field
The present invention relates to the pull back open fast wrench of back and forth operation of a kind of idle running, dallies when pulling back in especially a kind of position from holder crop W, and the operator can obtain the open fast wrench of the smooth-going operation sense of touch of " one-time-reach-place ".
Background technology
Open fast wrench is in conjunction with the pull back improvement hand-held tool of reciprocal service advantages of traditional open-end wrench and ratchet spanner idle running, and is very convenient during use, accumulated the improving technology of certain degree in the past.For example, No. the 228757th, TaiWan, China patent announcement (the pawl type Spanner structure of unidirectional precession " can "); Announce No. 278060 by (" tooth Nie formula revolution spanner "); Announce No. 327619, US5533428 (WO9615879) (" the ratchet-type spanner reaches with the ratchet-type spanner and rotates the method that can change assembly "); Announce patent cases such as M310772 (open-end wrench of unidirectional start " can "); And other country is as U.S. US7111529, US7077035, US3165015 patent case.In addition, monkey wrench also has similar reciprocal operating mechanism, as TaiWan, China patent announcement the 501515th (monkey wrench), and 511564 (the reversible monkey wrench of roller type) patent case, U.S. US7010999, TaiWan, China patent announcement 262313, U.S. US2 with ratchet spanner function, 879,681 etc.
The open-end wrench of No. 228757 exposure of patent announcement utilizes and to be located in the folder jaw of open driving part both sides it and one of " to move in the same way with driving spring " to the pawl/jaw that can contract (latch 2,3), makes spanner can reach the idle running back and forth effect of operation of pulling back.In this structure, the pawl/jaw (2,3) that can contract is to move along the spring pushing direction is forward and backward, with when spanner is operated clockwise, screw screw, and in the counterclockwise direction idle running pull back.Yet, because spanner when screwing (or unscrewing) screw, need be dependent on the reaction force that screw pushes against to be provided by the pawl that can contract in the time of can contracting pawl, the spanner of this kind function mode can contract pawl/jaw (2,3) though provide toothed surfaces and contact with screw, so that reaction force to be provided; Yet, on the one hand because of the direction of reaction force only produce component (toothed surfaces on the whole and the contact-making surface of screw between connecing not be to be 90 degree) on the toothed surfaces, dentalation uses factors such as can producing wearing and tearing long afterwards, and directly influences the operating characteristics of screw/unscrew; On the other hand, the size of wrench opening portion and actual nut size are variant, and can contract pawl/jaw (2,3) but in operating process, can move forward and backward and have the situation of progression wearing and tearing, be easy to generate the error in the interlock.This kind spanner uses to be gone up and inconvenience.
No. the 327619th, patent announcement, US5533428 cases such as (WO9615879) have slightly been improved aforesaid drawbacks, its main mode is to use " moving in the same way with driving spring " single contract pawl/jaw 15 and at the structure of wrench opening portion improve-that is, it defines the pawl 15 that can contract and has one second field of conjugate action 14, and it is parallel to first field of conjugate action 13 on first pawl 11.Yet this structure operates not smooth when idle running is pulled back.The one reason is, can a contract angle of the flank 75 of pawl 15 of nut 60 vicinities is easy to stumble and can contracts pawl 15 and stop the stroke of pulling back.Even bevel edge 16 is provided in this patent, attempt to reduce this problem, still can not avoid comprehensively.And, because complex structure, the size of wrench opening portion are big than the nut size, not only spanner weight is along with size increases, the screw/unscrew screw, and idle running two rightabouts operation of pulling back between, must go through repeatedly mobile test repeatedly, to seek the preferable point of application, this will expend the operating time, for professional user, very inconvenience.
Aforementioned or other similar problem is present in and variously is dependent in the spanner of " pawl that can contract that moves in the same way with driving spring "; For example, TaiWan, China patent announcement M310772 number, US3,165,015, US7,077,035, US7,111,529 etc.Another common problem of this kind spanner is: during the screw/unscrew spring, spring directly bears huge torsion with the pawl/jaw that can contract, and is unfavorable for service life.
No. the 501515th, TaiWan, China patent announcement, US7,010,999, TaiWan, China (patent of invention) discloses No. 200637692, the monkey wrench (adjustable spanner) of No. 511564 exposure of TaiWan, China patent announcement, adopt " the pivoted pawl " of difference, can avoid the problems referred to above generally.Know clearly it, announce No. 501515 the groove 14 that laterally runs through this fixed jaw 11 is set on fixed jaw 11, and be fixed in this two groove 14 with tumbler (pivoted pawl) 40,66 pivots of double-deck symmetrical structure, and make tumbler 40,66 double teams between stop section 15, reach by this spanner can be pulled back screw means/unscrew along direction rotation along other direction rotation idle running.Yet this patent still has following shortcoming: the tumbler of (1) its two kinds of forms (pivoted pawl) 40,66 is respectively the embodiment of double-deck symmetrical structure, T shape structure, complex structure; (2) tumbler 40,66 double teams are between two stop sections 15 of slotted eye, and can't screw in the slotted eye, and size is bigger so wrench opening is subject to the outstanding of tumbler, and is comparatively heavy, and can only be used on " monkey wrench ", is not suitable for open-end wrench; (3) spring 50,67 is located on the pivot, can make the elastic force of tumbler 40,66 resiliences less, and operation has some setbacks; (4) groove that is used for holding tumbler 40,66 penetrates Wrench head, so the intensity of spanner clamping part is relatively poor for running through groove 14 or perforation.No. the 511564th, TaiWan, China patent announcement, US7,010,999, and No. the 200637692nd, TaiWan, China patent disclosure communique the through-going recess that penetrates Wrench head in No. the 501515th, the aforementioned bulletin is modified to the circular arc C shape groove that does not penetrate and " driving rolls " that obtains higher-strength and stirred by spring with " tumbler 40,66 " in No. the 501515th, the aforementioned bulletin, to replace tumbler (pivoted pawl).Yet on the one hand because " driving rolls " area is big, being used for installing the fixed jaw that is somebody's turn to do " driving rolls " must have quite roomy area to hold this driving rolls; These prior arts can only be used for monkey wrench on the other hand, and to cooperate assemblies such as " movable jaw ", " worm screw ", the certain interlock screw/nut of ability etc. is part or working substance, and the mass activity spanner must be more heavy, operation inconvenience.
In various idle runnings were pulled back the spanner of back and forth operation, the required structure of the spanner of utilization " pivoted pawl " mechanism was comparatively simple for the spanner that utilizes " pawl that can contract that moves in the same way with driving spring " mechanism, has the advantage of low cost; Yet, the former design has high complexity, generally do not take off several shortcomings of row: (1) retraction pawl must cooperate the slide opening of " running through the folder jaw ", cause spanner folder jaw fragile structure, easily operating (2) retraction pawl that ruptures because of long-term high button power is designed to have the complicated field of conjugate action, maybe need cooperates a plurality of retraction pawls, with engaging screw/nut etc. is that part or working substance etc. are part or working substance, causes to make to be difficult for or manufacturing cost increases; (3) design of retraction pawl need be born great strength and be damaged easily; (4) hold screw/nut etc. be part be the part chamber, may adopt portable folder jaw and complex structure; Though or adopt integral type folder jaw but be part chamber profile complexity, cause operation to be difficult for.
Therefore, be necessary to provide a kind of open fast wrench, improve aforesaid drawbacks.
