Description of the Invention: [Technical Field to Be Invented by the Invention] The present invention is in the field of bicycles, and in particular, an invention for improving the structure of a bicycle. [Prior Art] According to the continuous improvement of the concept of leisure and entertainment, more and more people are gradually changing to the spiritual activities of pure pursuit of pleasure in the holiday, and the use of bicycles is more popular. One of the outdoor leisure activities, you can enjoy the idyllic wildness along the bicycle lanes along the bicycle lanes, or the depths of the deep valleys and the jungle trails of the explorers in the mountains. People can always rely on bicycles for mobility. The sturdy frame structure, steadily stepping on the pedals to the beauty of the heart. In order to ensure the safety of bicycle riding, the design of the brakes becomes one of the important structures. It is known from the prior art that a "synchronous brake" is the structure disclosed in the Republic of China Patent Application No. 97205063. The structural design is a synchronous brake device with a guiding structure between the two arm arms and capable of synchronous flat-balance action, the structure comprises a curved arched suspension frame, and the two are relatively coupled in a swingable configuration. The two sides of the suspension frame are connected to the arm of the arm, and the two armes are respectively provided with oppositely extending arms in the upper half and having a section overlapping, and a parabolic form is arranged between the overlapping portions of the two extending arms. a guiding portion and a sliding member that can abut against the guiding portion, and the guiding and interlocking structure formed by the guiding portion and the sliding member can effectively utilize the guiding linkage when braking The structure is designed to allow the two arm arms to produce a synchronous balance braking performance. 201118007 However, the above-mentioned conventional brake structure can provide the function of synchronous brake braking. However, if the front brake and the rear brake arrive at the same time or the first brake, the rider will move forward due to the force. Dumping or even flying out, causing a car accident and other regrets, and there is a need to improve. In view of this, the inventors have in-depth discussion on the above-mentioned practical creation problems, and actively pursued solutions through years of experience in R&D and manufacturing of related industries. After long-term efforts and research, they have finally succeeded in developing this book. Invented the "sports structure of bicycle synchronization segmentation" to improve the problem of custom creation. SUMMARY OF THE INVENTION The main object of the present invention is to solve the above problems and provide a "sliding structure of a bicycle synchronous segment", which enables the bicycle to be braked at the same time as the front and rear brakes, and can be segmented into a rear brake after the first operation. Synchronous segmentation structure of the brakes to improve the safety and stability of the brakes. In order to achieve the above-mentioned effects, the "bicycle synchronization segmented brake structure" of the present invention is provided with an integrator between the front and rear brakes of the front brake and the rear brake of the bicycle, so that the front brake line is pulled. At the same time, the front and rear brakes can be taken at the same time for the braking action. The integrator is composed of a box seat, a cover, a first pull block, a second pull block, a third pull block, and a linkage block, and the first pull block is stacked above the second pull block. And the third pull block is disposed under the second pull block, and the linkage block is disposed between the second pull block and the third pull block, and a long slot is formed at one end of the link block, When the third pull block is coupled, the interlocking portion of the second pull block and the third pull block can have an interlocking portion of an idle stroke. Secondly, the front part of the rear brake line is connected to the first pull block, and the front brake line is composed of a first line segment of the 201118007 and a second line segment. One end of the first line segment is connected to the front end of the vehicle. The end is connected to the second pull block, and one end of the second line segment is connected to the front brake device, and the other end is coupled to the third pull block. Further, a wire slot is defined in each of the two sides of the first pull block and the second pull block for receiving and positioning the front brake wire and the rear brake wire when the front brake wire and the rear brake wire are pulled, and the first pull block Correspondingly, the rear brake line is threaded over the outer side of the slot, and a positioning screw is locked to ensure that the positioning screw end abuts against the rear brake line, and the rear brake line is coupled with the first pull block. Further, the second pull block is corresponding to the outer side of the front line of the front y car line, and a positioning screw is also locked, so that the end of the positioning screw is fastened to the first line segment. And the first line segment and the second pull block are fixed and fixed. In addition, a slanting portion is disposed on the inner wall surface of the box seat, and one end of the third pull block is pivoted to the pivot portion by a positioning pivot rod, so that the third pull block is the second pull block. When the belt is moved, it is linked by a swing. After the cover is assembled with the box seat, the upper and lower ends are locked and fixed by the ring cover to protect the internal structure. Thereby, when the front brake line is initially pulled, the first pull block is first linked through the second pull block Φ, so that the rear brake line is pulled to drive the rear brake device to perform the braking action, and the second The pull block is linked to the idle travel of the third pull block at a preset distance. When the front brake line is further pulled, the rear brake line continues to drive the brake device to perform the braking action, and the front brake line passes through the brake line. The interlocking relationship between the second pull block and the third pull block drives the front brake device to perform the braking action, thereby achieving the braking effect of the synchronous braking section before and after the braking, thereby improving the safety and stability of the braking device. With regard to the technology, the means and the functions of the present invention, a better embodiment and a detailed description will be given below. It is believed that the above-mentioned items 201118007 and features of the present invention can be obtained from an in-depth and specific understanding.
