As shown in fig. 11, in order to avoid injury to the operator, the ball control device 3 further includes a guard 34 disposed around the bicycle 1, wherein the guard 34 is fixedly connected to the frame 31 at a front end and fixedly connected to the bicycle frame 12 at a rear end.

The working principle of the invention is as follows: when the single-wheel double-drum bicycle game device provided by the invention is used, the bicycle rear wheel 11 is lifted firstly, the fixing pin 252 is aligned with the dismounting groove 712, then the connecting shaft 251 is pushed inwards until the fixing pin 252 is positioned in the annular clamping groove 1211, and then the bicycle rear wheel 11 is put down, so that the fixing pin 252 leaves the notch of the dismounting groove and is clamped in the annular clamping groove 1211 to realize the fixed connection of the speed reducer and the bicycle, and the bicycle rear wheel 11 is just positioned on the roller 23. Then, the connection interface 311 of the ball control device 3 is connected with the front end of the bicycle frame 12, and the control device 33 is fixedly arranged on the bicycle handlebar 13.

When riding, the rear wheel 11 of the bicycle drives the roller 23 to rotate at the same time, the roller 23 drives the large gear 242 to rotate through the small gear 241 coaxially fixed on the roller 23, the large gear 242 drives the small sprocket 243 coaxially fixed on the roller 242 to rotate, the small sprocket 243 drives the large sprocket 244 to rotate through the chain 245, and the large sprocket 244 drives the wheel 22 coaxially fixed on the large sprocket 244 to rotate, so that the speed reducer moves along with the bicycle, and when the bicycle 1 turns, the connecting rod 5 connected to the bicycle frame 7 drives the single-wheel double-cylinder speed reducer 2 to synchronously turn along with the bicycle 1.

When the game device moves to the ball to be captured, the turning handle 3331 is turned down, the turning handle 3331 drives the turning wheels 3333 to turn together, the left and right control lines 3312 connected to the two turning wheels 3333 are tightened, and the hooking inclined surfaces on the inner sides of the turning wheels 3333 push the limiting block 3343 to turn backward around the trigger shaft 3342 while the ball-shooting trigger 3344 rotates forward. The lower end of the left and right control wires 3312 pulls the left and right ball control plates 322 inwardly to rotate inwardly in a ball holding state, compressing the left and right shot-torsion springs 324 while capturing the ball. When the left and right ball control boards 322 are turned inwards to a ball holding state, the captured balls cannot be separated from the ball holding and shooting device 32, a certain gap is reserved between the ball holding and shooting device 32, and the captured balls can roll on the ground along with the movement of the ball holding and shooting device 32. At this time, the stopper 3343 also passes over the highest point of the trip inclined surface, enters the step formed between the highest surface and the lowest surface of the trip inclined surface 3341, and returns to the cocked position together with the ball-shooting trigger 3344 by the trigger torsion spring 3345. At this time, the rotating handle 3331 is slightly loosened, the rotating wheel 3333 rotates forward under the action of the reset torsion spring 3332 and the ball-shooting torsion spring 324, and the rotating wheel 3333 is limited to be in a cocked state because the limiting block 3343 enters the step formed between the highest surface and the lowest surface of the hooking-off inclined surface 3341. When the shooting point is moved to be shot, the shooting trigger 3344 is only required to be slightly shifted forwards, the trigger shaft 3342 drives the limiting block 3343 to rotate backwards, when the limiting block 3343 rotates to lose the limit on the hooking and unhooking inclined plane 3341, the rotating wheels 3333 rotate forwards rapidly under the action of the reset torsion springs 3332, the left and right control lines 3312 connected with the two rotating wheels 3333 are also pumped backwards rapidly under the action of the left and right shooting torsion springs 324, and when the limit is lost, the left and right ball control plates 322 drive the left and right shooting torsion springs 324 to rotate forwards rapidly and eject the limited balls.

The foregoing detailed description will be given for the purpose of illustration only, and the invention is not limited to the above-described embodiments, but is to be construed as merely illustrative of the principles of the invention, as long as they are within the scope of the invention.
