The first linking member has a second pivot portion, a second pushing portion and a second pulling portion. The second pivoting lion is coupled to the second connecting portion On the driving portion, the second pushing portion is on the Jr guiding surface. The second pulling portion is connected to the vehicle line. The distance from the second pulling portion to the second pivot portion is greater than the second pushing portion. The distance of the second pivot portion. Thus, when the first pull-up portion is pulled, the first link member can be pivoted in addition to the first solid-solid portion of the first step. a pivot portion is a shaft movement so that the first push portion pushes the second material surface to cause the second arm mountain red fixing portion to be pivoted; and when the second pull portion is pulled, the second portion In addition to interlocking the second arm, the second fixing portion is pivoted by the second fixing portion, and the second guiding portion is simultaneously driven by the second urging portion to push the first guiding portion to cause the first The arm is a shaft lion with the first fixing portion. The reaction force generated by the first pushing portion pushing the second guiding surface is pushed by the first pushing portion, or the first guiding surface is pushed by the first pushing portion Production The reaction force of the first pull-up portion or the second pull portion can be greatly reduced. Therefore, the load applied by the vehicle of the present invention is much smaller than that of the conventional bicycle brakes. The force applied when the arm is directly pulled by the brake wire. In addition, the H-arm to the first-solid material miscellaneous _ fine-phase car ^ is also affected by the tension of the first-linkage member, and also by the second linkage/leverage Thrust; in contrast, when the second arm is braked by the principle of the lever with the axis, in addition to receiving the first-square scale: the crotch portion is subjected to the first-she-thinness, and the arm system can generate more holding force.
