Structural improvement. [Prior Art] Please refer to the control line adjustment structure of the bicycle rear derailleur as shown in the first and second figures. The adjustment button 1G is screwed to the screw hole 13 t of the mouthpiece 12 of the rear derailleur H. The end of the control line 14 passes through the adjustment button 1 and is clamped by the clamping portion 16 on the link set 15. Pulling or releasing the control line 14 causes the link set 15 to be in contact with the fixed member 12, so that the moving member π-synthesizing the guide member 17 of the shaft member 17 is laterally moved by the link group 15 to The purpose of shifting shifting is achieved. The screwing or unscrewing of the adjusting button 10 in the screw hole 13 of the fixing member 12 adjusts the tension of the control line 14 to improve the use of the bicycle chain - after a period of time, it may be fatigued. Lai_The rear chain of the rear derailleur u causes a problem of noise. However, due to the control line adjustment structure of the conventional bicycle rear derailleur, the adjustment button 10 is screwed in the screw hole 13 of the _ 12, so that the (4) 嶋 forms a larger M s hai control line Μ in the control When the rear shifter u shifts the shifting speed, the pulling stroke is increased. * The response of the shifting speed is relatively late, and the control of the rear derailleur is relatively insensitive. In addition, the larger turning angle causes the control wire 14 and the adjusting button 10 to cause greater wear and tear, resulting in a problem of shortened service life. In this case, the creator has developed a design for the control line adjustment structure of the above-mentioned bicycle rear derailleur, which is lack of design and inconvenience caused by the lack of design. creation. [New content] The main purpose of this creation is to provide a control line adjustment structure improver for the rear derailleur that can make the control of the rear derailleur more sensitive and reduce the wear of the control line. Specifically, the control line adjustment structure improvement of the bicycle rear derailleur described in the present invention includes a rear transmission, a pivoting member, an adjustment sister, and a control line. Wherein, the rear derailleur comprises a fixing member, a connecting rod set, a moving part and a guide chain set. The fixing member is fixed to the rear of the bicycle, and the fixing member has a receiving groove and a through hole and is perforated through one of the receiving grooves. The two ends of the connecting rod are respectively connected to the fixing member and the moving member' for lateral movement of the moving member relative to the fixing member, and the connecting rod assembly has a clamping portion. The chain guide group is coupled to one side of the moving member. The pivoting member is movably disposed in the receiving slot and cannot be disengaged from the through hole. The pivoting member has a threaded hole extending through one of the opposite sides. The adjusting button has a stud for passing through the through hole and screwed in the screw hole, and the outer diameter of the stud is smaller than the through hole of the through hole at the 5th and 5th circumference of the S. The end of the control wire passes through the through hole and is caught by the stagnation portion. In this way, the pivoting member is movably disposed in the receiving groove of the fixing member, the stud of the adjusting button is screwed on the pivoting member, and the outer diameter of the stud is smaller than the structural design of the through hole. The adjustment button can be swung on the @piece, so that the use of the tooth is set in the adjustment button and the control line can be controlled when the control device of the lost portion controls the rear speed shifting In the adjustment between the lost parts. The P injury does not have a turning angle or the angle of the turning can be greatly reduced. In turn, the side control line is reduced by the _(four) speed stroke width, and the response of the secret building shifting is faster. Therefore, the control system of the transmission after this creation can be more sensitive than the conventional structure. In addition, the creation of the control line between the adjustment button and the clamping portion does not have a turning limb or can greatly reduce the turning limb, so that the degree of wear of the control line and the adjustment is better than the conventional structure. Small, but can greatly increase the service life. In the present invention, the pocket has a slot that extends into one side of the defining member, and the pivotal member can be inserted into the pocket by the slot. In the present invention, the container and the aging medium are cylindrical, and the pivoting member can be in the languating member, and the adjusting red can be fixed by the pivoting member. The pieces are oscillated in two opposite directions. In addition, the cavity and the yoke can also be divided into the column holes and the studs of the butterfly to increase the stability of the pivoting member on the fixing member.曰 In this creation, the pocket and the clasp can be set to correspond to a spherical shape.
