Novel EPB parking structure

The invention discloses a novel EPB parking structure. A turbine worm power head is mounted on the exterior of a clamp body, and a self-sleeve structure is coaxially connected with a self-adjusting shaft; the self-adjusting shaft extends into the clamp body and is connected with a self-adjusting base through an angled ballistic structure, the self-adjusting base is coaxially connected with a screwsleeve, the screw sleeve sleeves a screw rod through a thread, the screw rod is fixedly mounted in an inner hole of a piston, the piston is internally provided with an inner friction block, and the clamp body is provided with an outer friction block; a fixed frame is fixed to the portion, outside the screw sleeve, of the clamp body, the screw sleeve is provided with a return spring, and the return spring is separately connected to an outer flange step of the screw sleeve and the fixed frame; a second hole retaining ring is fixed in the inner hole of the piston, the screw rod is provided witha step, a conical spring i
