The locking member 80 is inserted into one of the ninth and tenth pivot holes 600, 602, the ninth and tenth right pivot holes 720, 722 and the ninth and tenth left pivot holes 730, 732, and the brake lever 60 is pulled clockwise or counterclockwise around the ninth and tenth pivot holes 600, 602 into which the locking member 80 is inserted, so that the protrusion 65 drives the push rod 66 to move into the master cylinder 70 or move out of the master cylinder 70. Therefore, the present invention can automatically adjust the distance between the braking rod and the protrusion 60 to the inner plate (clockwise for right hand braking and counterclockwise for left hand braking) according to the preference of the rider by inserting the locking member 80 into the ninth and tenth pivot holes 600, 602, the ninth and tenth pivot holes 720, 722 and the ninth and tenth pivot holes 730, 732, so as to avoid the danger caused by the bad hand feeling of holding and pressing the braking rod.

In addition, in the above, the push rod 66 has a stopper 660, and the stopper 660 is disposed at the end of the push rod 66.

Please refer to fig. 14A, which is a schematic structural diagram illustrating a fastening member 80 of a sixth embodiment of the present invention disposed in a ninth fulcrum hole 600. As shown in the drawings, the locking member 80 of the present embodiment is inserted into the ninth right pivot hole 720, the ninth fulcrum hole 600 and the ninth left pivot hole 730 of the master cylinder 70 (please refer to fig. 13), so that the brake pull rod 60 rotates clockwise or counterclockwise around the ninth fulcrum hole 600 inserted into the locking member 80, and therefore, the distance between the position of the ninth fulcrum hole 600 and the position of the protrusion 65 is the braking distance D9 of the present embodiment.

Similarly, as shown in fig. 14B, it is a schematic structural diagram that the locking member 80 of the sixth embodiment of the present invention is disposed at the position of the tenth fulcrum hole 602. The locking member 80 of the present embodiment is inserted into the tenth right pivot hole 722, the tenth fulcrum hole 602 and the tenth left pivot hole 732 of the master cylinder 70 (please refer to fig. 13), so that the brake lever 60 rotates clockwise or counterclockwise around the tenth fulcrum hole 602 where the locking member 80 is inserted, and therefore, the distance between the tenth fulcrum hole 602 and the protrusion 65 is the braking distance D10 of the present embodiment.

As can be seen from the above two paragraphs, since the braking force distance D9 formed by the locking member 80 inserted into the ninth fulcrum hole 600 is different from the braking force distance D10 formed by the locking member 80 inserted into the tenth fulcrum hole 602, the softness and hardness of the hand feeling of the user when gripping the brake pull rod 60 are different, so that the user can select the hydraulic brake operating device 6 suitable for the hand feeling of the user by using the locking member 80.

Furthermore, the user only needs to insert the locking member 80 into one of the ninth and tenth pivot holes 600, 602, the ninth and tenth right pivot holes 720, 722 and the ninth and tenth left pivot holes 730, 732, so as to adjust the distance between the ninth and tenth pivot holes 600, 602 and the protrusion 65, without adjusting the brake lever 60 after detaching it, so that the present invention can utilize the locking member 80 to increase the convenience of the user in changing the distance between the ninth and tenth pivot holes 600, 602 and the protrusion 65.

The utility model discloses not limited to above-mentioned embodiment, all adopt and the utility model discloses similar structure and method realize the utility model discloses all modes of purpose all are within the protection scope of the utility model.
