Abstract:
The present invention relates to a bow for archery which is composed of a string (10), a handle (20), and blades (30). The handle (20) includes a supporting groove (22) and a clamp (25), and the blade (30) includes a locking groove (32) and a locking protrusion (35). A pocket block (40) with a recessed groove (45) of a closed curve shape is interposed between the handle (20) and the blade (30). Therefore, the present invention prevents joining pieces including the clamps from being arbitrarily pulled out from a joined portion during the process in which a user joins the string with blades so that physical injuries to a user or accidents are prevented.
