Description of the invention: [Technical field to which the invention belongs], just the invention of the invention - the secret of the secret, the shape of the handle; the handle and the crank of the funeral allowance, (10) tolerances or assembly due to manufacturing processing The gap is generated, and the assembly efficiency of the bicycle can be quickly assembled to improve the overall assembly efficiency of the bicycle, and the stability of the crankshaft rotation when the pedal is stepped on is increased, and the ball bearing on the outer side of the left and right teeth is replaced when the ball bearing is worn, and The distance between the right crank and the five-way pipe and the left crank can be adjusted by tightening the dust cover and the ball bearing to the side of the right crank with a loop. [Prior Art] [0002] According to the general crank structure of a bicycle, a crank combination is arranged in a five-way pipe with a lower tube, a seat tube and a rear fork tube, and the rider can smoothly step on the rotation function. The conventional crank-shaft group is provided with a ball bearing on both sides of the mandrel with a crank device, and the mandrel is mounted on the five-way pipe, and the snail is reused on both sides of the mandrel. The ring screwes its mandrel into the five-way pipe; however, the way of directly placing the ball bearing wheel on the mandrel not only combines the time-consuming work time to affect the overall assembly efficiency, but also may be due to the overall accuracy problem. However, the twist lock cannot be tightly closed, so that the crank structure is loosened, and the other is 'because of the crank disk; the end is the transmission side of the power, and the contact area of the ball bearing is small, only the point or partial contact And because the rider stepped on the force to apply force on the side - after a period of time, the ball bearing on the side may be damaged, skewed, and the crank rotation stability is insufficient when pedaling, the overall can withstand the deterioration of the pedaling force Those who have mentioned the above species Deletion, there is a necessity of improving the structure of the conventional composition of a crank. 099113609 Form nickname A0101 Page 4 of 17 page 0992023986-0 201136800 [0003] In view of this, the inventors are well aware of the lack of use, and modify and improve, while at the same time pursuing a good spiritual concept, and The invention has been successfully tested by its many years of professional experience, and after many ingenuity and experimentation, to provide a crank combination adjustment structure. SUMMARY OF THE INVENTION [0004] The main object of the present invention is to provide a crank combination adjustment structure for the bicycle five-way pipe and crankshaft assembly and adjustment, which is lost when the left and right teeth are screwed together The sides of the five-way pipe are combined with the frame to eliminate the tolerances caused by the manufacturing and processing of the five-way pipe 'left and right tooth bowls and the left and right crank handles, or the gaps generated by the assembly, and can be quickly assembled to improve the overall bicycle. Assembly efficiency, increase the stability of the crankshaft rotation when the pedal is applied by force. The ball bearing on the outer side of the left and right teeth is easy to change when worn, and the dust cover and the ball bearing can be tightened by a bundle of rings.
