[0006] Through the above technical solution, the piston housing can be protected by the piston protection box to prevent the piston cylinder from being dented due to collision during daily use, which would cause the piston to be unable to slide and affect the braking effect.

[0007] As a further improvement of the above solution, a rotating shaft is rotatably connected inside the rotating rod, a piston rod is fixedly connected inside the rotating shaft, both ends of the piston rod pass through the side walls of the rotating shaft and extend, and a piston cylinder is fixedly connected inside the piston protection box.

[0008] Through the above technical solution, the piston rod moves in the piston cylinder, thereby compressing the air in the piston cylinder.

[0009] As a further improvement of the above solution, the piston rod is slidably connected to the inside of the piston cylinder, and an air outlet is opened on the right outer shell. The air outlet passes through the side wall of the piston protection box and extends to the inside.

[0010] As a further improvement of the above scheme, a limiting groove is provided on the right outer shell, a push rod is slidably connected to the inside of the right outer shell, an anti-slip ring is fixedly connected to the outer wall of the push rod, the anti-slip ring is slidably connected to the inside of the limiting groove, a left outer shell is provided on the right side of the right outer shell in contact with the right outer shell, and the right outer shell and the left outer shell are fixedly connected by screws.

[0011] Through the above technical solution, such a configuration is to drive the anti-slip ring to move when the tow rod moves, and the limiting groove can limit the anti-slip ring to prevent the two anti-slip rings from detaching from the right outer shell and the left outer shell, thereby preventing the push rod from detaching from the left and right outer shells.

[0012] As a further improvement of the above scheme, a limiting groove is provided on the left outer shell, the interior of the left outer shell is slidably connected to the left push rod, a docking hole is provided on the left outer shell, the docking hole is connected to the air outlet, and a sliding rod is fixedly connected to the interior of the left outer shell.

[0013] Through the above technical solution, the purpose of such arrangement is to transport the compressed air in the piston tube to the inside of the left shell through the air outlet and the docking hole, thereby pushing the push rod to move.

[0014] As a further improvement of the above scheme, the right end of the sliding rod passes through the left outer shell side wall and extends, the right end of the sliding rod is fixedly connected to the left side of the right outer shell, the outer wall of the sliding rod is slidably connected with a push plate, and the ends of the two push plates away from each other are fixedly connected to the sides of the two push rods close to each other.

[0016] As a further improvement of the above solution, the outer wall of the sliding rod is fixedly connected with a U-shaped spring piece, the side wall of the U-shaped spring piece is fixedly connected with the push plate, and the inner wall of the U-shaped spring piece is fixedly connected with a brake pad.

[0017] Through the above technical solution, the U-shaped spring piece can be compressed by the push plate, and the U-shaped spring piece will drive the brake pad to move, so that the brake pad contacts the wheel and plays a braking role.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The utility model passes the brake line through the wire tube and then unscrews the fixing bolt to form a gap between the clamping plate and the rotating rod. Then the brake line is passed through the gap and the fixing bolt is tightened to fix the wire tube between the rotating rod and the clamping plate, which can effectively prevent the brake line from loosening and causing slow brake response or even brake failure.

[0020] The utility model pulls the brake line, and the movement of the brake line drives the rotating rod to rotate, and the rotation of the rotating rod drives the movement of the rotating shaft. The rotation of the rotating shaft pushes the piston rod to move toward the inside of the piston cylinder, thereby moving the gas in the piston cylinder, and the gas pushes the push rod on the right outer shell to move toward the brake pad. The push rod drives the anti-slip ring, and the limiting groove limits the anti-slip ring to prevent the anti-slip ring from detaching from the right outer shell, thereby preventing the push rod from detaching from the right outer shell. At the same time, the compressed gas enters the docking hole through the air outlet, and then pushes the push rod on the left outer shell to move toward the brake pad. The two push rods push the push plates closer to each other, and the push plates compress the U-shaped spring pieces inwardly. The U-shaped spring pieces drive the two brake pads to move toward the wheels, and at the same time squeeze the two sides of the wheels, which can improve the braking effect and shorten the braking time.
