Description

The head-swinging type ratchet two-purpose wrench of ease of assembly

Technical field:

The utility model relates to the ratchet spanner technical field, refers in particular to a kind of head-swinging type ratchet two-purpose wrench of ease of assembly.

Background technology:

In mechanical processing industry, ratchet spanner is very common hand-operated tools, it utilizes the engagement of ratchet and pawl teeth to realize directed dismounting and installation to securing member, for convenience's sake, someone is divided into two sections with the handle body and the ratchet head of handle, and connect with rotating shaft, referring to Fig. 1-2: the ratchet spanner of this structure includes ratchet head 8, handle body 1 and rotating shaft 3, described ratchet head 8: the one end has connecting portion, this connecting portion is an extended contiguous block 7, on contiguous block 7, be provided with an axis hole between two parties, the middle part of the other end is provided with ratchet installing hole 5 and ratchet installing hole, side at ratchet outer surface and ratchet installing hole inner surface is respectively arranged with jump

ring mounting groove

10 and 4, in ratchet installing hole and ratchet installing hole, be equipped with by ratchet 9, ratchet 12, spring 13, jump ring 11 is connected to respectively in the jump

ring mounting groove

4 and 10 of ratchet installing hole and ratchet, the folk prescription of ratchet 12 and spring 13 control ratchets 9 to the application of force to screw or to unscrew nut, described handle body 1: the one end is provided with twists the open-end wrench that bolt or nut are used, two auricles 6 that are clipped in outside described contiguous block 7 lateral surfaces are extended in the both sides of the other end, 2, at two

auricles

6,2 middle part is provided with axis hole, axis hole on the contiguous block 7 and auricle 6, axis hole on 2 connects with rotating shaft 3, realize the adjustable angle of ratchet head 8 and handle body 1, to adapt to different installation or removal positions, its weak point is: this reversible ratcheting tool is when assembling, the jump ring groove 10 of ratchet 9 and the installing hole 5 interior jump ring grooves 4 of ratchet head 8 all could be assembled at upside or downside simultaneously, otherwise, jump ring 11 can not be stuck in the jump ring groove 4 of ratchet head 8, the installation direction of the jump ring groove 10 of adjustment ratchet 9 and the jump ring groove 4 of ratchet head 8 needs the regular hour, and, in case direction is got wrong, then can't assemble, must readjust the installation direction of the jump ring groove 4 of the jump ring groove 10 of correct ratchet 8 and ratchet head 8 could assemble, this adjustment process can increase more built-up time, causes production efficiency low.

Summary of the invention:

The purpose of this utility model provides a kind of head-swinging type ratchet two-purpose wrench of ease of assembly.

The utility model is achieved in that the head-swinging type ratchet two-purpose wrench of ease of assembly, 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, and it is characterized in that: the opposite side at ratchet installing hole inner surface also is provided with the jump ring mounting groove.

The outstanding compared to existing technology advantage of the utility model is:

1, the installation direction of the jump ring groove in the installing hole of ratchet jump ring groove of the present utility model and ratchet head is unrestricted, all can assemble at both forward and reverse directions, makes the direct labor easy to assembly, quick, and production efficiency improves, and production cost reduces, alternative existing product;

2, the utility model can be applicable on ratchet spanner of the same type.
