Description
Technical Field
The utility model belongs to the technical field of manual hardware and tools's technique and specifically relates to a limit structure of ratchet spanner's switching-over button.
Background
When the reversing button of the common ratchet wrench rotates left and right, if the reversing button is not limited, the reversing button can freely rotate by three hundred sixty degrees and cannot perform a reversing function, a position on the handle where the reversing button is installed is milled into a shape similar to a triangle, the reversing button is located inside the triangle, the two sides of the triangle limit the angle of the reversing button rotating left and right, and the ratchet wrench is inconvenient to do and difficult to machine and start.
Disclosure of Invention
The utility model aims at solving the above problems and providing a limit structure of a reversing button of a ratchet wrench, which can save the process of processing the triangular position and save the cost.
The utility model adopts the technical proposal that: the utility model provides a limit structure of ratchet spanner's switching-over button, includes handle, end cover, top cap screw, pawl spring, right pawl, reversing shaft, left pawl, reversing shaft screw, steel ball, switching-over button, rivet, steel ball pressure spring, square joint, its characterized in that still includes the switching-over separation blade, be equipped with a penetrating part in the middle of the switching-over separation blade, this part appearance is unanimous with the reversing shaft appearance, can install the switching-over separation blade on the reversing shaft, and the switching-over separation blade can be along with the reversing shaft rotation from side to side, respectively is equipped with a salient position about the switching-over separation blade, when the switching-over separation blade is along with the reversing shaft rotation from side to side, when rotating a locating position, the arch was touched the handle inner wall about the switching-over separation blade on, can prevent the reversing shaft and continue to rotate, played spacing effect.
