Through adopting above-mentioned technical scheme, torsional spring makes the rectification fin main part be in the biggest angle when the footboard is not stepped on, increases the stability that the starching ship was gone, pulls the rectification fin main part through the cable when the footboard was stepped on, and the half withdrawal of rectification fin main part reduces stability and the resistance of traveling this moment, is convenient for turn round and acceleration and goes, and in the rectification fin main part was withdrawn first casing when the footboard was stepped on completely, made the rectification fin main part no longer produce the resistance to the starching ship that goes, is convenient for turn round fast and go fast.

Further, the pulleys are three, and the inhaul cable is movably connected with the three pulleys.

Through adopting above-mentioned technical scheme, the transmission direction of cable strength is changed through the setting of three pulley to the cable can transmit power pulling rectification fin main part when the user steps on the footboard, so that the staff is controlled it.

Further, the rectifying fin main body is movably connected with the first shell.

Through adopting above-mentioned technical scheme, the torsional spring makes the rectification fin main part be in biggest angle when the footboard is not stepped on, increases the stability that the starching ship was gone, pulls the rectification fin main part through the cable when the footboard was stepped on, and the half withdrawal of rectification fin main part reduces stability and resistance that traveles this moment.

Further, the section of the pedal is I-shaped, and the pedal is movably connected with the second shell.

Through adopting above-mentioned technical scheme, the footboard is the I shape and makes its both ends all can play limiting displacement, avoids the footboard to follow the second casing and drops and lead to the unable normal control rectification fin of user, simple structure stability is better.

Further, two torsion springs are arranged and are symmetrically distributed.

Through adopting above-mentioned technical scheme, through the setting of torsional spring to the rectification fin main part continuously apply decurrent power, and then make the pedal not stepped on when the rectification fin be in the state of opening completely to increase the stability that thick liquid ship was walked.

Furthermore, the rectifying fin body is made of carbon fiber materials.

Through adopting above-mentioned technical scheme, carbon fiber material intensity is higher, and weight is lighter simultaneously, makes the rectification fin be difficult to take place the fracture phenomenon at actual application in-process, also can not excessively increase the weight of thick liquid ship simultaneously.

In summary, the utility model has the following advantages:

according to the utility model, through the arrangement of the pedal, the stay rope, the pulley and the torsion spring, when the pedal is not stepped on, the torsion spring enables the rectifying fin main body to be at the maximum angle, so that the running stability of the paddle ship is improved, when the pedal is stepped on, the stay rope pulls the rectifying fin main body, at the moment, the rectifying fin main body is retracted to reduce the running stability and the running resistance, the paddle ship is convenient to turn around and fast run, when the pedal is fully stepped on, the rectifying fin main body is retracted into the first shell, the rectifying fin main body does not generate resistance to the paddle ship in running, the paddle ship can be convenient to quickly turn around and fast run, the rectifying fin can be quickly changed according to different environments, and the ship stopping is not required to be regulated.
