An electronic handbrake is a technology that realizes parking braking by an electronic control method. Its working principle is the same as that of a mechanical handbrake, that is, the friction generated by the brake disc and the brake pads is used to control parking braking. Only the control method has changed from the previous mechanical handbrake lever to an electronic button; and the parts that are screwed together with bolts or screws to play a fastening role, which are components that all production and manufacturing machinery must use, are divided into several categories such as carbon steel, stainless steel, non-ferrous metals (such as copper) according to different materials.

A galvanized gasket is arranged on the other side of the inner cushion layer, a positioning block and a round rod are fixed on the inner side wall of the galvanized gasket, the positioning block is arranged in the outer groove, and the round rod is arranged in the round hole.
[0007] Furthermore, the convex block and the thrust nut are of an integral structure, and the inner groove is in communication with the inside of the thrust nut.
[0008] Further, multiple groups of the side grooves and inner grooves are equidistantly arranged on the thrust nut. One end of the outer support plate is equidistantly arranged on the inner cushion layer, and a threaded structure is provided on the inner side wall of the inner cushion layer.
[0009] Further, the galvanized gasket is a hexagonal hollow structure.
[0010] Further, a nut structure is fixedly engaged at the end of the pin shaft.
