Description
Technical field
The present invention is a kind of geared assembly of instrument, refers to that one provides user to adjust working head to suitable angle orientation, in order to the design of operation especially.
Background technology
Wrench is widely used in locking and unscrews screw tightening, so as to assembling or the spare part dismantling all kinds of industry.The spare part finished product of all kinds of industry little to home appliances greatly to precision instrument, therefore operating Wrench process can be restricted because of the position of operation and space size, cause the operation Wrench that user can not be certain, and provide suitable twisting resistance with locking or unscrew screw tightening.
In order to overcome the restriction in space, increase the convenience of user's force, relevant dealer, by Wrench integrally formed for tradition, improves as working head can adjust the structure of angle by holding rod relatively simultaneously.Refer to No. M376389th, TaiWan, China patent announcement " structure for controlling swinging head of spanner ", it comprises it and comprises a tool heads, a lever and a guiding mechanism, wherein: this tool heads one end is provided with one for the drive division driven, the other end is provided with an embedding head, and this lever one end is provided with one first pivot ear and one second pivot ear, this embedding head-clamp is placed between the first pivot ear and the second pivot ear, and is pivoted with the first pivot ear and the second pivot ear and combines, this guiding mechanism comprises one and is opened in accommodating hole lever is positioned at towards tool heads between the first pivot ear and the second pivot ear, one vertically communicates in accommodating hole and the embedding hole passed through out toward lever side, one is located at the joggle piece in accommodating hole, and one is located at adjustment part in embedding hole, wherein be provided with in this accommodating hole two ends respectively with the elastomer that joggle piece and accommodating hole are inner butted, and be provided with in embedding hole two ends respectively with the elastic component that adjustment part and embedding hole are inner butted, and this adjustment part radial direction is provided with towards a concave surface of accommodating hole and to face, face of should supporting is engaged with embedding head for pushing and pressing joggle piece and tool heads must not be rotated relative to lever, and concave surface is for the retraction of joggle piece one end, joggle piece and embedding head are departed from, namely tool heads obtains and freely rotates relative to lever, this elastomer pushing and pressing joggle piece compel toward embedding head direction to.
But " structure for controlling swinging head of spanner " of prior art, though overcome the restriction in space, makes embedding head be able to relative lever adjustment angle orientation and uses.But, prior art be the kenel of multiple tooth engagement with the angle of fixing embedding head, therefore must have the high teeth portion of fineness, just can reach stable engaging between teeth portion and the teeth portion of embedding head, otherwise also produce gap time fixing and cause stationary state built on the sand.So, the disappearance having processing cost high and time-consuming.In addition, when operating spanner, the teeth portion of joggle piece and embedding head can operate the force direction of spanner because of the torsion of action and user, and allows teeth portion need bear larger active force, and causes the abrasion of teeth portion after Long-Time Service.If after the stressed abrasion of the field of conjugate action of joggle piece both sides, when joggle piece and embedding head engage each other, its engagement can be unstable, and concentrate the teeth portion be engaged between both sides, and the situation more accelerating to wear away occurs.
Therefore, be necessary to be researched and developed and be minimized teeth portion abrasion, and make embedding head and joggle piece be able to strong fix, and the geared assembly of the instrument of low cost of manufacture.
Summary of the invention
Technical problem underlying to be solved by this invention is, overcomes the above-mentioned defect that prior art exists, and provides a kind of geared assembly of instrument, and its abrasion situation reducing teeth portion occurs, and makes working head and the firm tool angle orientation of holding rod; It reaches effect of strong fix with low cost of manufacture.
