The working principle of the invention is as follows: the use of the equipment is divided into two stages, wherein the first stage is the normal use state of the tricycle, the hand gear is firstly adjusted to the leftmost side, the upper bridge lock structure of the equipment is in a closed state, an upper layer power arm in the upper bridge lock structure is downward, a driven lock arm is downward in the closed state, so that a lock column is tightly attached to a connecting arm of a fixed cylinder of an upper bridge, double-end fixed cylinders at two ends of the upper bridge cannot rotate, a double-beam fixed structure at the rear side of a tricycle body is kept in a vertical state, and the tricycle body is like a normal tricycle; the second stage is the upper axle opening state of the tricycle, firstly, the hand gear is adjusted to the rightmost side, in the process, the anti-falling spring connected with the bottom end of the hand gear pulls the hand gear to the right side and prevents the hand gear from moving to the left side, at the moment, the bearing shoe ring is far away from the double-axle connecting column and drives the reversing arm to move towards the upper side, so that the upper layer power arm and the driven locking arm in the upper axle locking structure move upwards to drive the locking column therein to be far away from the fixed cylinder connecting arm, so that the double-end fixed cylinders at the two ends of the upper axle structure can rotate, in the process, the saddle and the saddle frame of the tricycle are relatively fixed with the upper beam of the tricycle, the pedal and the lower beam of the tricycle are relatively fixed, therefore, when a person rides on the tricycle, the pedal and the saddle are of two different structures, the tricycle body is divided into two steering structures, when the tricycle body turns to the left, the steering handle is manually controlled, the steering handle drives the steering transmission frame to rotate towards the left side by taking the steering handle as a center, a rotating shaft at the front end of the steering frame in the steering structure rotates in a small range to drive a middle-side steering rotating shaft of the equipment to rotate, and further drives a steering connecting sleeve of the equipment to move towards the left side, because the adjusting bolt plays a role of limiting the steering angle adjusting cylinder, the steering connecting sleeve drives a double-wheel steering connecting shaft in the steering structure to integrally move towards the left side, the energy of the leftward movement is transmitted to fixed bolt columns and end-side fixed groove blocks at two ends of the double-wheel steering connecting shaft to simultaneously move towards the left side, because the end-side steering rotating shaft is arranged in the end-side steering rotating shaft sleeve, a wheel side transmission arm in the steering structure can be pulled towards the left side, because the wheel side transmission arm is connected with a wheel axis sleeve, the wheels are driven to rotate towards the left side, and when, at the moment, the center of gravity of the whole vehicle body deviates to the right side, because of artificial control, the characteristic of artificial sitting and stepping by using the vehicle body can lead the upper beam of the vehicle body to deviate to the left side, thereby reducing the negative effect of the gravity center to the right caused by turning to the left side, in the process, the upper beam of the tricycle deviates to the left side integrally relative to the lower beam, the upper bridge structure of the tricycle also deviates to the left side relative to the lower bridge, in addition, the front left wheel and the front right wheel of the tricycle can deviate to the left side, the deviation process is that the upper bridge deviates to the left side, the front wheel fixing shaft of the tricycle inclines to the left side integrally, the wheels of the tricycle are driven to deviate, in addition, the lower bridge arch connecting piece can also rotate because of the effect of the fixed structure connecting pin shaft at the bottom end, therefore, the lower bridge arch connecting piece rotates to the left side by taking the fixed structure connecting pin shaft as the center, the tricycle still carries out lateral deviation to the left side, so that the whole deviation process is completed, when turning is completed, the steering structure of the tricycle restores to the state of the front side, the upper axle and the lower axle of the tricycle also restore to the state of being vertical upwards, and meanwhile, when the tricycle turns to the right side and turns to the left side, all structures and devices rotate towards the opposite directions, and the state is the opening state of the upper axle structure of the tricycle.

The foregoing is a preferred embodiment of the present invention, and it will be apparent to those skilled in the art that variations, modifications, substitutions and alterations can be made in the embodiment without departing from the principles and spirit of the invention.
