Hand fixation band

Abstract

A hand fixation band includes a fastening band, a damping element and a sliding arm. The fastening band has a main portion, and a connecting portion protruded outward from one end of the main portion. A free end of the connecting portion protrudes downward to form a first protruding portion. The damping element is assembled to the fastening band. A top surface of an inner side of the damping element is recessed downward to form a first recess. A bottom surface of the damping element is recessed upward to form a second recess. The first protruding portion is assembled in the first recess. The sliding arm is connected with the fastening band and the damping element. One end of the sliding arm protrudes upward to form a second protruding portion. The second protruding portion is assembled in the second recess.
