Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0019] like Figures 1 to 3 As shown, it is an embodiment of the utility model. The piston retaining ring described in this embodiment includes a retaining ring body 1 and a fastener 2. The brake pad 3 is provided with a matching piece 4. One end of the fastener 2 is connected to the matching piece 4 on the brake pad 3 and constitutes a locking end, and the other end is detachably connected to the retaining ring body 1.

[0020] It can be understood that the fitting member 4 is fixedly connected to the brake pad 3 , and a through hole is provided on the retaining ring body 1 , through which the fastener 2 passes to be connected to the fitting member 4 .

[0021] It comprises a fixed shaft 21 , and the matching piece 4 and the fastener 2 are both provided with fixed holes 41 of the same size, the fixed shaft 21 is connected to the fixed hole 41 , and the size of the fixed hole 41 matches the size of the fixed shaft 21 .

[0022] It can be understood that when the fastener 2 is connected to the fitting 4 , the fixing holes 41 on the fastener 2 and the fitting 4 relatively form a channel for the fixing shaft 21 to pass through.

[0023] Wings 11 are provided at both ends of the clamp body 1 , and at least one bend is provided on the wing 11 .

[0024] It is understandable that in reality, the piston retaining spring on the brake pad 3 cooperates with the piston, and the piston retaining spring cooperates with the piston slot on the piston, and the brake pad 3 and the piston can be closely matched by the force between the piston retaining spring and the piston slot. The bent wing 11 can enhance the force between the piston retaining spring and the piston slot to prevent the wing 11 from sliding against the piston.

[0025] It comprises a connecting rod 12, both ends of which are respectively connected to the wing pieces 11 arranged at the left and right ends of the clip body 1, and the connecting rod 12 is a bow-shaped structure.

[0026] It is understandable that the cross-sectional length of the fin 11 on the circlip body 1 is usually longer than the diameter of the piston slot, so the length of the connecting rod 12 connecting the two fins 11 is also longer than the diameter of the piston slot. When the circlip body 1 is inserted into the piston slot, the connecting rod 12 will strengthen the elastic force of the fin 11, making the circlip body 1 and the piston more firmly connected.

[0027] The fastener 2 is a bolt, and a fastening nut 22 is provided on the fastener 2, and a wedge-shaped serration is provided at the bottom end of the fastening nut 22.

[0028] It can be understood that the fastener 2 is a bolt, the fastening nut 22 is arranged on the fastener, and the wedge-shaped serrations at the bottom end of the fastening nut 22 make the fastener 2 and the matching piece 4 more stably connected and not easy to loosen.

[0029] It includes a first gasket 23, which is sleeved outside the fastener 2 and arranged between the fastening nut 22 and the mating piece 4. The first gasket 23 is provided with wedge-shaped serrations at both upper and lower ends. The first gasket 23 is arranged at the bottom end of the fastening nut 22 and the serrations at the top end of the first gasket 23 are adapted to the serrations at the bottom end of the fastening nut 22.

[0030] It includes a second gasket 24, which is sleeved outside the fastener 2 and arranged between the first gasket 23 and the matching piece 4. The second gasket 24 is provided with wedge-shaped serrations at both upper and lower ends. The second gasket 24 is arranged at the bottom end of the first gasket 23 and the serrations at the top end of the second gasket 24 are adapted to the serrations at the bottom end of the first gasket 23; when the fastener 2 and the matching piece 4 are locked and connected, the serrations at the bottom end of the second gasket 24 fit with the top end of the matching piece 4.

[0031] The serrations on the first gasket 23 and the second gasket 24 are in opposite directions, and the serrations on the first gasket 23 and the second gasket 24 are consistent in size.

[0032] It can be understood that the serrations at the upper and lower ends of the first gasket 23 and the second gasket 24 are in opposite directions, which can prevent the fastener 2 from rotating so that the fastener 2 will not loosen.
