Description
Technical field:
The utility model relates to the spanner technical field, is specifically related to a kind of fine stern ratchet spanner.
Background technology:
Traditional double offset ring spanner puts workpiece, after turning an angle, will unload and return, and puts again and could continue to pull workpiece, and operation is inconvenience very.Though and ratchet wrench ability rapid Continuous will be changed sleeve, and inconvenience is also arranged, structure is more complicated also.
The utility model content:
The purpose of the utility model provides a kind of fine stern ratchet spanner, and it is simple in structure, design exquisite, flexible operation, convenient, fast, fixing is strong and laborsaving.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises handle body 1, jump ring 2, ratchet carriage 3, two-way support tooth 4, bearing pin 5, steel ball 6 and spring 7; Connect ratchet carriage 3 through jump ring 2 on the handle body 1, be fixed with two-way support tooth 4 through bearing pin 5 on the handle body 1 of ratchet carriage 3 rear sides, two-way support tooth 4 rear sides have spring 7 through steel ball 6 tops.
The utility model is simple in structure, design exquisite, flexible operation, convenient, fast, fixing is strong and laborsaving.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the front view of Fig. 1.
The specific embodiment:
Referring to Fig. 1-2, this specific embodiment is to adopt following technical scheme: it comprises handle body 1, jump ring 2, ratchet carriage 3, two-way support tooth 4, bearing pin 5, steel ball 6 and spring 7; Connect ratchet carriage 3 through jump ring 2 on the handle body 1, be fixed with two-way support tooth 4 through bearing pin 5 on the handle body 1 of ratchet carriage 3 rear sides, two-way support tooth 4 rear sides have spring 7 through steel ball 6 tops.
During use, when a left side pushes away two-way support tooth 4 up the time, two-way support tooth 4 is around bearing pin 5 rotations, and the left side tooth meshes with ratchet carriage 3 external tooths.Under the top power of steel ball 6 and spring 7, be in the state of often nibbling.When external force when exert oneself in a left side, two-way support tooth 4 will drive ratchet carriage 3 and do and turn clockwise, and then tightens the right-handed nut.After pulling certain angle, 1 repercussion of handle body is return, and ratchet carriage 3 teeth and two-way support tooth 4 left teeth are thrown off.Repeat the 1 positive and negative operation of handle body, right-handed nut fast can screw.
In like manner, promote two-way support tooth 4 the right teeth and ratchet carriage 3 external tooths and realize the switching-over engagement, when oppositely pulling handle body 1 again and coming back operations, the left-handed nut of can screwing fast.
This specific embodiment is simple in structure, design exquisite, flexible operation, convenient, fast, fixing is strong and laborsaving.
