Description
Technical field
The present invention relates to a kind of spanner bandle structure, refer to a kind of double (end) wrench especially and lever has the function spanner bandle structure turned to.
Background technology
Spanner is one of common hand-held tool, and its head kenel comprises open-end wrench, double offset ring spanner, ratchet spanner or combination wrenches; General spanner bandle is in flat and have equivalent length in order to laborsaving operation, when at a narrow space or when need use spanner with special angle, easily because the fixed structure aspect of its lever causes operational inconvenience even cannot use.
In order to improve above-mentioned use problem, creator is had to propose No. 574972nd, TaiWan, China patent number " spanner gripping portion structural improvement ", as shown in Figure 1, this spanner 10 shank 101 mainly has one first lever 11 and the docking of one second lever 12 is formed, this the first lever 11 end loops is provided with multiple stopper slot 111, this the second lever 12 end is provided with a tank 121, this tank 121 inside is provided with elastic component 13 and a pearl body 14, this is first years old, second lever 11, end, one end mat one shaft member 15 groups of 12 connects involutory, by this, as shown in Figure 2, the tank 121 of this second lever 12 is involutory with a wherein stopper slot 111 of this first lever 11, this pearl body 14 for this elastic top support and be placed between this tank 121 and this stopper slot 111 with blocking locate this first, second lever 11, 12, and common wrench 10 is as shown in Figure 3 by this cylindric shaft member 15 pivotable, make spanner 10 head 102 be diverted to being convenient to user and operate use angle.
It should be noted that, the shaft member 15 of common wrench 10 is as shown in Figure 2, place this first, second lever 11,12 end along the radial Y of this shaft member 15 respectively by two latches 16 and be placed in an annular groove 151 constitutors at these shaft member 15 two ends, but, when this spanner 10 shank 101 is reversed in practical operation, the spinning force F1 that it is axle center that the component bestowing strength not only has with shaft member 15, more may produce an axial forces F2 because operator exerts a force improper, cause following problems:
1, when common wrench 10 shank 101 rotates, this spinning force F2 will directly put on this latch 16, and make its end face involutory because this first, second lever 11,12 only connects with this shaft member 15 groups, this axial forces F2 also can be applied directly on latch 16 when producing, and the stability of the docking commutating structure making common wrench 10 unique obviously weakens;
2, the spinning force F1 of common wrench 10 is with this shaft member 15 for axle center, and this pearl body 14 Impact direction is parallel with the axial X of this shaft member 15, will weaken the blocking locating effect of this pearl body 14.
