Abstract
The utility model discloses a dodecagonal double offset ring spanner which comprises a spanner body, wherein two spanner nozzles are arranged at the two ends of the spanner body, a first ratchet seat and a second ratchet seat are arranged in the inner holes of the two spanner nozzles respectively, and the first ratchet seat and the second ratchet seats are used for spacing in an axial direction and circumferentially arranged in the inner holes of the two spanner nozzles in a rotating and matched manner; a groove communicated with the inner hole of each spanner nozzle is formed on the spanner nozzle, a lifting jack is arranged in the groove, one end of the lifting jack is hinged with the inner wall of the groove, the other end of the lifting jack is propped against the teeth on the outer lateral walls of the first ratchet seat and the second ratchet seat through a lifting jack spring, a dodecagonal hole is formed in the center of the first ratchet seat, and a convex duodecimal prism is arranged in the center of the second ratchet seat. The dodecagonal double offset ring spanner not only can be used for tightening or releasing a dodecagonal screw, but also can be used for tightening or releasing an internal dodecagonal screw, and the dodecagonal double offset ring spanner can also be used at a narrow part without a sufficient rotation space.
Description
Technical field
The utility model relates to the hand-operated tools field, specifically is a kind of 12 jiaos of double offset ring spanners.
Background technology
12 jiaos of double offset ring spanners of prior art mainly are used for tightening or unclamp 12 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 dodecagon of endoporus for matching with 12 jiaos of screws of pulling mouth.12 jiaos of double offset ring spanners of this structure can only be used for tightening or unclamp 12 jiaos of screws, but also will change 12 jiaos of double offset ring spanners in the use again for interior 12 jiaos of screws, make troubles to people's operation like this.In addition; These 12 jiaos of double offset ring spanners are in the process of using; Particularly at the narrow and small position of machine, when 12 jiaos of double offset ring spanners do not have enough rotation spaces, can only the mouth of pulling of 12 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 12 jiaos of screws, can tighten or unclamp interior 12 jiaos of screws again, and at the narrow and small position that does not have enough rotation spaces also employable 12 jiaos of double offset ring spanners.
The technical solution of the utility model is; A kind of 12 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 dodecagon hole, and the center of the second sour jujube seat is provided with 12 prisms of an evagination.
After adopting above structure; 12 jiaos of double offset ring spanners of the utility model compared with prior art; Have the following advantages: 12 jiaos of screws can tightened or unclamp in the dodecagon hole at the center of the first sour jujube seat of these 12 jiaos of double offset ring spanners; Interior 12 jiaos of screws can tightened or unclamp to 12 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 12 jiaos of double offset ring spanners do not have enough rotation spaces, also need the dodecagon hole of 12 jiaos of double offset ring spanners or 12 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.
