Claims (3)

[Scope of utility model registration request] (1) This project is a new assembly device for a bicycle that can be used as a single-wheel vehicle, and mainly consists of (a power wheel frame), (a) a coupler that connects the connecting plate to the side frame of the vehicle frame and the front support frame, and (c) a coupler to the front wheel support frame. The front wheels are connected to the brackets, (m) the handle with the hollow support tube inserted into the front wheel support frame, (k) the saddle with the hollow support tube inserted into the rear support tube, and (to)) the rear wheels to transmit power and run the car. The coupler connects the vehicle frame and the front wheel support frame, or the two are separated, the handle is replaced with a saddle, and square shafts are installed at both ends of the front wheel axle to drive the front wheels. An assembly device for a single-wheeled bicycle, which is characterized in that it can be assembled into a single-wheeled bicycle to form a single-wheeled bicycle. (2) The coupler of the bicycle assembly device described in item 1 above mainly fixes the rear edge to the horizontal frame of the vehicle frame and the front end of the front support frame,
Fitting tanks are provided on both sides of the front edge, and a connecting plate is provided with one or several hooks on the top and bottom of the front end, and is fixed to the support frame of the front wheel, with one or several hooks formed therein corresponding to the hooks. It includes a connecting bracket that has a support shaft pivoted thereon and has a convex edge with a cutout in a part corresponding to the fitting tank of the connecting plate, and the hanging hook is hung on the support pivot in the bracket and the convex edge is provided. and the fitting tank are adapted to fit together. (3) The bicycle assembly device support shaft described in item 1 or 2 above is provided through the connection bracket, has an adjustment nut at one end of the spiral, an eccentric hole at the other end, and has a removable shaft. A tension cap, which has a large hole and a small hole in both walls, is fitted into one end of the eccentric hole of the support shaft, and then one end with a spiral is protruded into the small hole of the tension cap and tightened with a nut. The shaft passes through the eccentric hole of the pivot and the tension cap, and the other end has a large hole as a rotation bearing, and a coupler rotation eccentric shaft is provided with a grip formed at the end, and by rotating the grip at a certain angle, the eccentricity can be adjusted. The position of the s-axis is moved within the eccentric hole and the support shaft is tightened, so that the convex edge of the fixing bracket is firmly clamped into the fitting tank of the connecting plate, and the hanging hook is also tightly clamped. To be characterized by being.
