Description
Technical field
The present invention is a kind of geared assembly of instrument, refers to that especially a kind of user of providing adjusts working head to suitable angle orientation, in order to the design of operation.
Background technology
Wrench is widely used in locking and unscrews screw tightening, so as to assembling or dismantle the spare part of all kinds of industries.The spare part finished product of all kinds of industries little to home appliances greatly to precision instrument, therefore operating Wrench process can be restricted because of position and the space size of operation, 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 application of force simultaneously, relevant dealer is the integrally formed Wrench of tradition, improves as the working head structure of holding rod adjustment angle relatively.Refer to No. M376389th, TaiWan, China patent announcement " structure for controlling swinging head of spanner ", it comprises that it comprises a tool heads, a lever and a guiding mechanism, wherein: this tool heads one end is provided with one for the drive division driving, 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 with the combination that is pivoted of the first pivot ear and the second pivot ear, this guiding mechanism comprises that one is opened in the accommodating hole being positioned on lever between the first pivot ear and the second pivot ear towards tool heads, the one embedding hole that vertically communicates and also pass through out toward lever side in accommodating hole, one is located at the joggle piece in accommodating hole, an and adjustment part of being located in embedding hole, wherein in this accommodating hole, be provided with two ends respectively with the inner butted elastomer of joggle piece and accommodating hole, and in embedding hole, be provided with two ends respectively with the inner butted elastic component in adjustment part and embedding hole, and this adjustment part is radially provided with towards a concave surface of accommodating hole and and supports face, the face that should support must not rotate relative to lever tool heads for pushing and pressing joggle piece with the engagement of embedding head, and it is recessed and for the retraction of joggle piece one end, joggle piece and embedding head are departed from, tool heads obtains relative to lever and freely rotates, this elastomer pushing and pressing joggle piece toward an embedding direction compel 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 and adjusts angle orientation use.Yet the kenel that prior art is multiple tooth engagement, with the fixing angle of embedding head, therefore must have the tooth portion that fineness is high, just can reach engagement stable between tooth portion and the tooth portion of embedding head, otherwise also produce gap fixedly time, cause stationary state built on the sand.So, there is the high and time-consuming disappearance of processing cost.In addition, when operation is during spanner, the application of force direction that the tooth portion of joggle piece and embedding head can operate spanner because of the torsion that moves and user, and allow tooth portion need bear larger active force, and cause the abrasion of tooth portion after long-term use.If after the stressed abrasion of the field of conjugate action of joggle piece both sides, when joggle piece and embedding are intermeshing, its engagement can be unstable, and concentrate the tooth portion between both sides that is engaged in, and the situation of more accelerating abrasion occurs.
Therefore, be necessary to be researched and developed and be minimized tooth 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.
