Brief description of the drawings
Fig. 1 is a kind of stereogram, and a preferred embodiment of the utility model ratchet spanner is described;
Fig. 2 is a kind of side view, illustrates that a body and a driving head of this preferred embodiment has respectively a body height and a calibrated altitude;
Fig. 3 is a kind of top view, illustrates that this body of this preferred embodiment and this driving head have respectively a body width and a normal width.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is elaborated.
Consult Fig. 1 and Fig. 2, a preferred embodiment of the utility model ratchet spanner.This ratchet spanner comprises a hand-holding segment 2 and a construction section 3.
This construction section 3 comprise the body 31 an of one end that is arranged on this hand-holding segment 2, energy around self axis be arranged at rotatably this body 31 driving head 32, be separately positioned on a tumbler 33 and a removal part 34 on this body 31, an and holding firmware 35 being arranged on this driving head 32.
Consult Fig. 2 and Fig. 3, along on self axis of this driving head 32, this body 31 has a body height h, and the part that this driving head 32 protrudes from this body 31 has a calibrated altitude H.Along self axis of vertical in fact this hand-holding segment 2 and vertically on the straight line of self axis of this driving head 32, this body 31 has a body width d, and this driving head 32 has a normal width D.
This driving head 32 meets DIN3122 specification, and each uses specification to have corresponding preferably normal width D and calibrated altitude H.
When this driving head 32 meets 1/4 inch of industrial application specification, when DIN3122 code requirement uses, want to provide 6.2kg/m moment of torsion 1.3 times, that is 8.06kg/m.Now the ratio (d/D) of this body width d and this normal width D, between 2.91～3.23, is 3.03 at the present embodiment.The ratio (h/H) of this body height h and this calibrated altitude H, between 0.97～1.19, is 1.08 at the present embodiment.
This driving head 32 in the time meeting 3/8 inch of industrial application specification, when DIN3122 code requirement uses, want to provide 20.2kg/m moment of torsion 1.3 times, that is 26.26kg/m.Now the ratio (d/D) of this body width d and this normal width D, between 2.78～2.99, is 2.96 at the present embodiment.The ratio (h/H) of this body height h and this calibrated altitude H, between 0.90～1.06, is 1.00 at the present embodiment.
This driving head 32 in the time meeting 1/2 inch of industrial application specification, when DIN3122 code requirement uses, want to provide 50.2kg/m moment of torsion 1.3 times, that is 65.26kg/m.Now the ratio (d/D) of this body width d and this normal width D, between 2.48～2.64, is 2.62 at the present embodiment.The ratio (h/H) of this body height h and this calibrated altitude H, between 0.89～1.02, is 0.96 at the present embodiment.
Due to this tumbler 33, this removal part 34, and this holding firmware 35 familiar content of industry for this reason, therefore be not repeated herein.
Via above explanation, the advantage of the present embodiment can be summarized as follows:
Relatively the present embodiment and commercially available specification are 1/4 inch, 3/8 inch respectively, and the ratchet spanner of 1/2 inch, can find no matter be the ratio (d/D) of this body width d and this normal width D or the ratio (h/H) of this body height h and this calibrated altitude H, the present embodiment is all less than commercially available prod.That is meeting under DIN3122 specification situation, the utlity model has the advantage of small volume, therefore can save material cost and reach lightweight, and because volume is little, it is convenient in narrow space operation and easily storage also to have advantages of.
