Description
Technical field
The utility model relates to the hand-operated tools field, specifically is a kind of ten jiaos of double offset ring spanners.
Background technology
Ten jiaos of double offset ring spanners of prior art mainly are used for tightening or unclamp ten jiaos of screws, and its structure generally comprises wrench body, and the one or both ends of said wrench body are provided with pulls mouth, the said decagon of endoporus for matching with ten jiaos of screws of pulling mouth.Ten jiaos of double offset ring spanners of this structure can only be used for tightening or unclamp ten jiaos of screws, but also will change ten jiaos of double offset ring spanners in the use again for interior ten jiaos of screws, make troubles to people's operation like this.In addition; These ten jiaos of double offset ring spanners are in the process of using; Particularly at the narrow and small position of machine, when ten jiaos of double offset ring spanners do not have enough rotation spaces, can only the mouth of pulling of ten jiaos of double offset ring spanners be taken out indexing from bolt head again and is inserted in; More likely can't be inserted in and can not use, make troubles for people's normal use.
The utility model content
The technical problem that the utility model will solve is; Overcome the defective of above prior art; Provide a kind of and can tighten or unclamp ten jiaos of screws, can tighten or unclamp interior ten jiaos of screws again, and at the narrow and small position that does not have enough rotation spaces also employable ten jiaos of double offset ring spanners.
The technical solution of the utility model is; A kind of ten jiaos of double offset ring spanners with following structure are provided: it comprises wrench body; The two ends of said wrench body are provided with two and pull mouth; Respectively be provided with the first sour jujube seat and the second sour jujube seat in said two endoporus of pulling mouth, described first sour jujube seat and the equal axial limiting of the second sour jujube seat and circumferentially be engaged in rotationally in two endoporus of pulling mouth; Each pull mouth be provided with one with pull the groove that the mouth endoporus is connected, be provided with in the described groove one very heavy, the inwall of said very heavy end and groove is hinged, the very heavy other end through the tooth on very heavy spring and the first sour jujube seat and the second sour jujube seat lateral wall against; The center of the said first sour jujube seat is provided with the decagon hole, and the center of the second sour jujube seat is provided with ten prisms of an evagination.
After adopting above structure; Ten jiaos of double offset ring spanners of the utility model compared with prior art; Have the following advantages: ten jiaos of screws can tightened or unclamp in the decagon hole at the center of the first sour jujube seat of these ten jiaos of double offset ring spanners; Interior ten jiaos of screws can tightened or unclamp to ten prisms of the evagination at the center of the second sour jujube seat, very easy to use; In addition; Effect through very heavy and very heavy spring makes the first sour jujube seat and the equal one-directional rotation of the second sour jujube seat; And oppositely skid; Like this when ten jiaos of double offset ring spanners do not have enough rotation spaces, also need the decagon hole of ten jiaos of double offset ring spanners or ten prisms not taken out indexing from bolt head again and be inserted in, bring convenience for people's normal use.
As preferably; Described first sour jujube seat and the equal axial limiting of the second sour jujube seat and circumferentially be engaged in rotationally in two endoporus of pulling mouth; Be meant outer wall and two inwall matched in clearance of pulling the mouth endoporus of the described first sour jujube seat and the second sour jujube seat; And be equipped with radial ringed spacing preiection on the outer wall of the first sour jujube seat and the second sour jujube seat, two bore openings places of pulling mouth all are connected with a capping, and the outer face of said two cappings and two spacing preiections offsets.This capping can be taken off by screwdriver, so dismounting, maintenance are more convenient.
