Description

A kind of structure-improved of penetration ratchet spanner

Technical field

The utility model refers to a kind of structure-improved of penetration ratchet spanner.

Background technology

The use of spanner, concerning industrial circle now, be still one of indispensable hand-held tool, and in common mechanical factory, the workplaces such as auto repair shop, often can in the time of construction, use the spanner of various kind, for example: double offset ring spanner, box spanner, open-end wrench, the hand-held tool such as monkey wrench and ratchet spanner, help through the work of maintenance or assembling in order to assembling-disassembling bolt, ratchet spanner that wherein can unidirectional continuous braking, be to combine the practical feature of inner hexagon spanner and ratchet spanner and derivative creation, dealer's operating efficiency and industry quality are not only significantly promoted, and bring user and in the time of construction, have sizable convenience.

And general existing penetration ratchet spanner 200, wherein, refer to shown in Fig. 1, it is the combination signal exploded view for a kind of known penetration ratchet spanner and sleeve, one wrench body 201 is mainly to have a head 202, and in this head 202, there is the ratchet 203 of a unidirectional drive, on this ratchet 203, be to be equipped with a sleeve joint hole 204, this sleeve joint hole 204 is the dodecagon holes that communicate for two ends, and can be for being socketed on a sleeve 300, thus, user is assembling-disassembling bolt smoothly, and helps through the work of maintenance or assembling.

Again, above-mentioned known penetration ratchet spanner 200 structures learn it is to utilize the mode of sleeve joint hole 204 as the main socket sleeve 300 of this wrench body 201, again, in the time that user uses this wrench body 201 to be socketed on this sleeve 300, rotate this sleeve 300 simultaneously, and this sleeve 300 is in the interior easy generation displacement of this sleeve joint hole 204 or the situation that comes off, and the application of force and rotate this sleeve 300 smoothly, therefore, must make the sleeve joint hole 204 of this wrench body 201 again be socketed on sleeve 300, just can again rotate this sleeve 300, therefore, existing penetration ratchet spanner 200 easily produces inconvenience and affects the smoothness of work in the process using.

But above-mentioned known penetration ratchet spanner 200 structures still have some scarce frauds, and in the streets improve for its scarce fraud, refer to shown in Fig. 2, be to be the known penetration ratchet spanner of one and the structure improved combination signal of sleeve exploded view; Mainly wherein to there is a connector portions 301 in this sleeve 300, and the periphery wall of this connector portions 301 is to be equipped with an annular groove 302, in this annular groove 302, be to be equipped with a spring retaining ring 303, thus, in the time that this connector portions 301 is engaged in the sleeve joint hole 204 of this head 202, this spring retaining ring 303 will elasticity be resisted against the inwall of this sleeve joint hole 204, and then can reach and fasten and fixing effect, to guarantee that in the process of the person's of re-using operation, this sleeve 300 can be by coming off in this penetration ratchet spanner 200.

Therefore, because sleeve 300 structural improvements of this penetration ratchet spanner 200 can have the sleeve 300 of multiple corresponding different size bolts conventionally, therefore adopt the fixing mode of above-mentioned joint, and must be on each sleeve 300 be provided with this spring retaining ring 303, and then increase many production costs and time, and in order to make this spring retaining ring 303 can be resisted against the inwall of this sleeve joint hole 204, this spring retaining ring 303 must the recessed polygon that is converted into, and slightly protrude from this annular groove 302, and these spring retaining ring 303 difficulty of processing are higher, volume production is difficult for, simultaneously more because be not easy to maintain the shape of this spring retaining ring 303, so the elastic force of this spring retaining ring 303 is also wayward, cause this penetration ratchet spanner 200 with the sleeve 300 of different size in conjunction with time, meeting tension when easily some sleeve 300 of generation is incorporated into this sleeve joint hole 204, and some sleeve 300 is excessively loose while being incorporated into this sleeve joint hole 204.

Have mirror therewith, the utility model person is for the shortcoming of existing ratchet spanner, and the problem facing further investigation, and does the research and development of upgrading and improve the scarce fraud of habit formula for ratchet spanner, and this is design aim of the present utility model.

Utility model content

The purpose of this utility model is to provide one to be easy to processing and manufacturing and production cost is low, and can avoid sleeve in sleeve joint hole, to produce straight-line displacement or the structure-improved of the penetration ratchet spanner that comes off.

For reaching above-mentioned purpose, the structure-improved of a kind of penetration ratchet spanner provided by the utility model, it is to have a wrench body, and the front end of this wrench body is to be formed with a head, this head is to be concaved with a storage tank, and this head opposite side is more equipped with first perforation communicating with this storage tank; An and ratchet, it is to be arranged in this tank, and this ratchet upper limb is vertically provided with one first neck, and lower edge is provided with one second neck, this first neck is to be arranged in this first perforation, and then this ratchet sleeve is limited be positioned at this storage tank, separately, this ratchet is axially arranged with a polygonal sleeve joint hole along this, and the internal perisporium of this sleeve joint hole has multiple composition surfaces, again, this ratchet is to be equipped with an annular groove in the periphery wall of this first neck, wherein this annular groove has certain degree of depth, makes the end angle place of this sleeve joint hole adjacent bond face be formed with respectively a perforation; One C shape clasp is to be arranged in the annular groove of this ratchet, and this C shape clasp is to protrude from this perforation place, and then forms a limiting section; Also have a back of the body lid, it is the bottom face that is covered on this storage tank, and this back of the body to cover be to be equipped with one second perforation, make this back of the body lid second bore a hole and sheathed the second neck that is limited in this ratchet by this simultaneously.

As preferred version, wherein, this sleeve outside is provided with multiple stopper faces, and end angle place between two adjacent stopper faces is provided with a draw-in groove, makes the described limiting section can be for clip in described draw-in groove.

As preferred version, wherein, the end angle place of this sleeve joint hole adjacent bond face is provided with respectively a cancave cambered surface vertically.

The structure-improved of a kind of penetration ratchet spanner provided by the utility model, in the time that a set of cylinder is engaged in this sleeve joint hole by user, this limiting section will elastic bolster guide in this sleeve, and this sleeve can be fixed in this sleeve joint hole, to guarantee in user in the process of this penetration ratchet spanner of operation, the sleeve joint hole of this ratchet limits the situation that produces straight-line displacement on this sleeve, thus, penetration ratchet spanner of the present utility model is not used in and on each sleeve, is all provided with spring retaining ring, just can combine with the sleeve of different size, therefore not only can reach and be easy to processing and manufacturing, production cost is low and avoid sleeve in sleeve joint hole, to produce the situation coming off, and reach the scarce fraud of the existing penetration ratchet spanner of effective improvement.
