Fourth, the creative description (1) [New type of this creation is a kind of stability and control when the front body produces torsion force [prior art] Press, currently a variety of functions, because of the general market and electric drive wheel, Then it can be more suitable for various technical fields. About the "Bicycle with Connecting Shaft", there is a connecting shaft between the rear body bracket and the current body: the horizontal state of the rear body can be maintained to increase the body. The overall structure is practical and beneficial. The average bicycle is popular among consumers because of its combination of sports, leisure and entertainment, and is popular all over the world. The driving styles are diverse, mainly divided into two types of simple foot force; and among them, the wheel form was transformed into a tricycle in the early stage to increase the smoothness of its sliding. “: Consumers of the age group. 遂[Content] Solving technical problems and technical means) Smooth I ^ W knows the structure of the three-wheeled bicycle. In order to maintain the overall body, the G-bend speed is 21-wheel-wheeled with a differential, and the two-wheeled door can be balanced by the == ” However, its components are complex, ί * Pit ^ , differential state, w to the wheelbase between the two wheels needs to be increased, so that the car is a larger, and when the current twist, the overall body is awaiting, resulting in stability And poor handling. The dry body can't easily turn around. (Technical means to solve the problem) The creator has this in mind, thanks to the long-term use of various bicycles.

Page 6 M287283 Twisting, Creation Description (2) The research and integration of the bicycle is mainly due to the fact that the front body bracket is provided with a shaft hole on the outside of the pedal body of the rear body, and then penetrates into the connector. The utility model utilizes a nut lock to fix the position shaft portion; so that the current fork can generate the front body to be twisted with the front fork, thereby improving the concept that the overall vehicle structure can reach safe sliding, and the front side of the front body and the rear body of the rear body are designed. There is a connecting shaft, and the front end of the other bracket is provided with a shaft hole for connecting the shaft, and then a shaft is provided with a joint between the one and the other, and the sleeve is formed by a ring and a washer. It is still possible and beneficial. When the torsion force is turned, the body is pivoted and the utility body pivots as the connecting shaft portion of the control shaft of the body hand after the connecting shaft portion is maintained, and the group is connected with a bearing, and the moving body is moved. The pivoting of the connection, the horizontal shape 'to make the whole (according to the efficacy of the prior art) is known from the above description, the following several functions of the creation: 1, heart: South body stability and bicycle design by the bicycle, the connection The shaft can maintain the horizontal state of the rear body, so that it can be manipulated. 2, smooth sliding: this creation: before the reversal, and regardless of the level of the two t temple, to provide a safe and smooth member 21 simple f: Because the creation of this room is early and easy to assemble, practical and practical compared to the prior art, Authentic achievability··Because this creation has a pivoting action that provides the front fork, the bicycle design with the same body stability and the handlebar connection shaft, or the slope's body can still be saved. A bicycle with a connecting shaft is beneficial to the person.
