The panel 10 may be made of acrylic board or the like for mounting on a door. The handle 11 is rotatably mounted in the first mounting hole 102 of the panel 10 by a snap spring, a bearing, or the like. The force-releasing boss 12 is substantially bar-shaped, and the force-releasing boss 12 is relatively movable in the axial direction of the first accommodation hole 112, but the force-releasing boss 12 cannot be rotated relative to the handle 11, so that the force-releasing boss 12 and the handle 11 are rotated synchronously when the handle 11 is rotated. The elastic element 13 may be a spring. The fixing case 14 is fixedly mounted to the panel 10 by screws or the like, or the fixing case 14 is mounted to a door, i.e., indirectly mounted to the panel 10 through the door.
