In a preferred embodiment, the brake handle 12 includes a stop portion 15 and a grip portion 16; one end of the limiting part 15 is rotatably connected with the fixed seat 11, and the other end is fixedly provided with a handle part 16; the limiting part 15 is provided with a brake cable mounting hole 17 for wearing the brake cable; the junction of spacing portion 15 and grab handle portion 16 is provided with recess 18 along the one side of handlebar 1 diameter direction far away from handlebar 1.

In a preferred embodiment, the limiting frame 2 comprises a crank 21 and a compression bar 22; the turning rod 21 is arranged in a V shape, and the tip end part is a turning elbow part; the two turning rods 21 are symmetrically arranged and respectively arranged on two sides of the brake handle 12; a pressing rod 22 is fixedly arranged between the same ends of the two turning rods 21 corresponding to the grooves 18, and the other ends of the two turning rods are respectively and rotatably connected with two sides of the fixed ring 13; the two ends of the compression bar 22 along the axial direction are fixedly connected with the two turning bars 21 respectively.

Referring to fig. 1 and 2, in this embodiment, two connecting rods 21 are disposed on two sides of the brake handle 12 and can rotate around the connection with the fixing ring 13, the two connecting rods 21 are fixedly connected with each other by a compression rod 22 between one ends, the compression rod 22 is driven to rotate when the connecting rod 21 rotates, and when the elbow of the connecting rod 21 rotates below the handlebar 1, namely, the spring pin mechanism 3, the elbow can press the spring pin 32, so that the spring pin mechanism 3 fixes the elbow.

In a preferred embodiment, the latch mechanism 3 comprises a mounting box 31, a latch 32, a spring 33 and a push button 34; the second fixing ring 14 is fixedly provided with a mounting box 31 on one surface far away from the brake handle 12 in the diameter direction; the inside of the mounting box 31 is set to be empty; spring pins 32 are symmetrically and movably arranged inside the mounting box 31 along the two ends of the axial direction of the compression bar 22; a spring 33 is arranged between the two spring pins 32; the two ends of the spring 33 along the axial direction are fixedly connected with the two spring pins 32 respectively; the springs 33 are provided with two or more; one end of the spring pin 32, which is far from the spring 33 in the axial direction, penetrates through the wall surface of the mounting box 31 and extends out of the mounting box 31;

the bottom surface of one end of the spring pin 32, which is close to the spring 33 along the axial direction, is fixedly provided with an inclined groove 35; the center of the bottom surface of the mounting box 31 is movably provided with a push button 34; the bottom end of the push button 34 penetrates through the wall surface of the mounting box 31 and extends out of the mounting box 31, and the two ends of the top end along the axial direction of the spring pin 32 are fixedly provided with a pressure head 36 corresponding to the inclined groove 35; the indenters 36 are disposed inside the corresponding inclined grooves 35.

Referring to fig. 1 and 2, in this embodiment, two inclined grooves 35 are provided corresponding to two pressing heads 36, the inclined grooves 35 cooperate with the pressing heads 36 to control the position of the spring pin 32, and the depth of the inclined grooves 35 gradually increases from the inside to the outside of the mounting box 31 along the axial direction of the spring pin 32. When the push button 34 is pressed, the two pressing heads 36 move toward the inside of the mounting box 31, and the pressing heads 36 interact with the inclined grooves 35 to bring the two elastic pins 32 close to each other, so that the elastic pins 32 retract into the inside of the mounting box 31; when the push button 34 is released, the two spring pins 32 are separated from each other by the elastic force of the spring 33, and the restoring action of the spring 33 causes the two spring pins 32 to rapidly eject the mounting box 31.

The two spring pins 32 are arranged corresponding to the two turning bars 21, and when the brake handle 12 is used normally: when the turning rod 21 rotates to the spring pin 32, the two spring pins 32 respectively block the turning parts of the turning rods 21 on the two sides, so that the turning rods 21 cannot be fixed, and the use of the brake handle 12 is prevented from being influenced; when the brake handle 21 needs to be pressed all the time: the brake handle 12 is pressed, the pressing rod 22 is pressed into the groove 18, at the moment, the elbow part of the elbow rod 21 is blocked by the spring pin 32, because the spring pin 32 has a certain inward retracting elastic force under the action of the spring 33, at the moment, the pressing rod 22 is pressed by manually applying force, the elbow part of the elbow rod 21 passes through the spring pin 32, the spring pin 32 firstly retracts inward, then the elbow part is fixed by quick reset and ejection, the elbow part is prevented from moving, namely, the position fixing of the limiting frame 2 is completed, and the limiting frame 2 always presses the brake handle 12 through the pressing rod 22.

In a preferred embodiment, the spring pin 32 is rounded off in the axial direction away from the end face of the spring 33.

Referring to fig. 1 and 2, in this embodiment, the rounding provides for easier passage of the elbow portion of the lever 21 over the spring pin 32 when pressed, increasing smoothness.
