Description
Technical field
The present invention relates to a kind of spanner structure, refer to a kind of facility assembling especially and there is the spanner structure that the integral type manufacturing economic benefit prevents from applying workpiece disengaging.
Background technology
Spanner is a kind of instrument that fortification operation is commonly used, be used for turning tight, turning the various positioning workpieces such as loose screw rod or nut, and spanner is of a great variety, comprise open-end wrench, combined type spanner, double offset ring spanner, monkey wrench and box spanner etc., existing spanner structure has generally included a head and shank, this head place has an accommodation space, be used for accommodatingly applying workpiece (screw rod or nut), and rely on this accommodation space and this apply after absorption surface agrees with, carry out the operation of rotation force at this shank, be used for reaching and turn tight, turn the object that pine applies workpiece.Though existing spanner structure technology can rely on this spanner rotation process to turn tight to reach, turn the labor-saving effect that pine applies workpiece, but still have its disappearance to exist, such as: when the accommodation space of this spanner agrees with after contact applies workpiece, due to problems such as construction environment space or force application angle directions, what often make the head of spanner very easily depart to have located to agree with applies workpiece, now namely need again again by sheathed for the accommodation space of head, locate to agree with and apply workpiece, make operation quite has some setbacks and loses time, and when this head (accommodation space) with apply workpiece produce relative dislocation move and exert a force more violent, even have the unsafe condition causing hand to be wounded that falls through that exerts a force.
Existing technology No. 483367 Patent Cases as novel in TaiWan, China occurring to misplace when preventing spanner and apply work piece operations of being correlated with, it provides a kind of spanner structure to improve, and it mainly comprises: a spanner, a revolving part, a upper cover and a ring form jointly; Spanner effect end tool one accommodating hole, accommodating hole can be accommodating for a revolving part, a draw-in groove is established in the face, one side that accommodating hole and upper cover cover, one revolving part outside is provided with tooth engaged and center is provided with a polygonal groove, one upper cover can be covered on above the accommodating hole of spanner, and establishes an annular groove relative to the draw-in groove place of spanner, and the stop surface establishing to be less than the polygonal groove of revolving part in upper end, can be inserted in a ring between the draw-in groove of spanner and the annular groove of upper cover, namely upper cover relies on ring to set firmly or be hubbed on spanner.The prior art (novel No. 483367 of TaiWan, China) is though can rely on the stop surface of upper cover to prevent screw piece from coming off on spanner, but because this upper cover relies on the annular groove setting of itself and the draw-in groove of spanner to arrange, and coordinate a ring to be inserted in fix therebetween and in addition, make its component loaded down with trivial details and manufacture assembling comparatively inconvenience, do not meet the economic benefit of manufacture, aobvious nonideal design.
Existing relevant this type of technology and for example novel No. 494830 Patent Cases of TaiWan, China, it provides a kind of ratchet spanner anti-taking off structure to improve, it consists predominantly of: ratchet spanner effect end tool one accommodating hole, the space of accommodating hole can be accommodating for lower toroidal ring on ratchet and two, and accommodating hole proximal portion ring establishes an annular groove to be pivoted for upper ring; One ratchet outside is provided with tooth engaged and center is provided with a polygonal groove; On two, lower toroidal ring is provided with embedding end, and is fixedly arranged on ratchet two upper and lower end face place respectively, and the embedding end of upper lower toroidal ring also staggers in the polygonal groove convexedly stretching in ratchet by embedding end mutually.The prior art (novel No. 494830 of TaiWan, China) in ratchet spanner just (instead) rotation process time, though upper (lower) ring can be relied on to carry out the blocking of screw piece to prevent and the coming off of wrench, but in the setting and two of its accommodating nose end place annular groove of this ratchet spanner lower toroidal ring with the use of, have equally component loaded down with trivial details and manufacture assembling compared with inconvenience, do not meet the economic benefit of manufacture, and the embedding end of this ring is very easily out of shape or extrudes and inside contract when spanner rotates force operation, form the major defect of overall spanner external form, also the necessity improved in the lump is had, therefore, it manufactures the disappearance on assembling, the important topic that should be industry or have intelligence taxi should solve, overcome how to solve existing anti-detachment spanner.
Edge this, the present inventor does not attain the desirable fact in view of in the shortcoming in its manufacture assembling of existing anti-detachment spanner and structural design thereof, namely inventor sets about researching and developing its solution, wish to develop a kind ofly have more operational stability, the integral type of security and economic benefit prevents from applying the spanner structure that workpiece departs from, with service society masses and the development promoting this industry, satisfy the design when many and have generation of the present invention.
