Abstract
A structure of ratchet and junction comprises a driving head, a control loop, four clamp blocks, a ratchet and a cap head. The back end of the driving head is connected within a handle. The control loop is combined with the cap head and coats the driving head, four clamp blocks and a ratchet loop. The driving head has two containing spaces, each of which contains two clamp blocks. The two clamp blocks respectively have a spring used to bunt each other. The control loop has four convex poke rods. The poke rods toggle the two diagonal clamp blocks by turning the poke rods of the control loop in order to make the two diagonal clamp blocks off from the clamp to the ratchet loop. The other two diagonal clamp blocks bunt in the ratchet loop and, as a consequence, do the three-way control of counterclockwise and clockwise braking to reach the aims of double-clamp, increasing twisting force and no escape. The structure has large twisting force, balance and no inclination. The structure can clamp the ratchet indeed and make the ratchet not to escape. The structure adopts an extension type driving rod structure and can adjust the length of the driving rod. The structure is flexible and convenient to use.
