[0006] A door sheet metal, wherein the door sheet metal is provided with a handle hole, and an edge of the handle hole extends inwardly to form a mounting portion;

[0007] A handle base, wherein the handle base has a concave cavity,

[0008] A handle body, wherein the handle body is installed in the concave cavity;

[0009] A switch cover plate, wherein the switch cover plate is fixed on the outside of the handle body;

[0010] A fixed connecting piece, which passes through the handle base, the handle body and the mounting portion in sequence and is fixedly connected to the switch cover; the fixed connecting piece is fastened to the switch cover and clamps the handle base, the handle body and the mounting portion;

[0011] The limiting structure is arranged on the handle base and is used to limit the fixed connection part.

[0012] Furthermore, the fixing connection member includes a screw, and the switch cover is provided with a thread matching with the screw, or a nut matching with the screw is embedded in the switch cover.

[0013] Furthermore, the limiting structure includes a hook disposed on the handle base, the screw is screwed in and causes the hook to elastically deform, and when the screw is screwed in to a set position, the hook recovers its deformation and clamps the screw, thereby limiting the screw along the thickness direction of the handle.

[0014] Furthermore, the screw is provided with a convex portion cooperating with the hook.

[0015] Furthermore, the shape of the protrusion is ring-shaped.
