Summary of the invention:
The purpose of this utility model provides that a kind of operating noise is low, long service life, can add the lubricated head-swinging type ratchet two-purpose wrench of low noise vocal cores of lubricating grease.
The utility model is achieved in that the head-swinging type ratchet two-purpose wrench that the low noise vocal cores is lubricated, include ratchet head, handle body and rotating shaft, described ratchet head: the one end has connecting portion, this connecting portion is an extended contiguous block, on contiguous block, be provided with an axis hole between two parties, the middle part of the other end is provided with ratchet installing hole and ratchet installing hole, side at ratchet outer surface and ratchet installing hole inner surface is respectively arranged with the jump ring mounting groove, in ratchet installing hole and ratchet installing hole, be equipped with by ratchet, ratchet, the single direction ratchet transmission mechanism that spring and jump ring are formed, described handle body: the one end is provided with twists the open-end wrench that bolt or nut are used, two auricles that are clipped in described contiguous block lateral surface are extended in the both sides of the other end, middle part at two auricles is provided with axis hole, axis hole on the contiguous block is connected with rotating shaft with axis hole on the auricle, is provided with the annular groove that repack with grease is used at the middle part of ratchet installing hole inner surface.
In annular groove, ratchet outer surface and the ratchet installing hole at above-mentioned ratchet installing hole inner surface middle part, be filled with lubricating grease.
The outstanding compared to existing technology advantage of the utility model is:
1, is provided with annular groove at the middle part on the face of cylinder of ratchet installing hole of the present utility model, in annular groove, be filled with lubricating grease so that the contact-making surface of ratchet and ratchet and ratchet and ratchet installing hole is lubricated, the one, the noise in the time of can effectively reducing work, reduce environmental pollution, the 2nd, owing to no longer carry out dry friction between parts, the component wear amount that feasible friction causes significantly reduces, and improve the service life of product;
2, the utility model can be applicable on product of the same type.

Fig. 1 is the perspective exploded view of prior art;
Fig. 2 is the cutaway view of ratchet head in the prior art, rotating shaft and handle body part;
Fig. 3 is a perspective exploded view of the present utility model.
The specific embodiment:
With specific embodiment the utility model is further described below, referring to Fig. 3: the head-swinging type ratchet two-purpose wrench that the low noise vocal cores is lubricated, include ratchet head 40, handle body 20 and rotating shaft 30, one end of ratchet head 40 has connecting portion, this connecting portion is an extended contiguous block 41, on contiguous block 41, be provided with an axis hole 411 between two parties, the middle part of the other end of ratchet head 40 is provided with ratchet installing hole 42 and ratchet installing hole, side at ratchet 80 outer surfaces and ratchet installing hole inner surface 421 is respectively arranged with jump ring mounting groove 801 and 423, in ratchet installing hole 42 and ratchet installing hole, be equipped with by ratchet 80, ratchet 80, the single direction ratchet transmission mechanism that spring 60 and jump ring 70 are formed, jump ring 70 is connected to respectively in the jump ring mounting groove 422 of ratchet installing hole 42 and ratchet 80, the folk prescription of ratchet 50 and spring 60 control ratchets 80 to the application of force to screw or to unscrew nut, one end 22 of handle body 20 is provided with twists the open-end wrench 221 that bolt or nut are used, two auricles 211 and 212 that are clipped in described contiguous block 41 lateral surfaces are extended in the both sides of the other end 21 of handle body 20, middle part in two auricles 211 and 212 is provided with axis hole 213, axis hole 411 on the contiguous block 41 is connected with axis hole 213 usefulness rotating shafts 30 on the auricle 211 and 212, is provided with the annular groove that repack with grease is used at the middle part of the inner surface 421 of ratchet installing hole 42.
