Multiple-in-one socket

摘要

A multiple-in-one socket includes a socket body having a first gradational cavity recessed in a first end of the socket body, and a second gradational cavity recessed in a second end of the socket body opposite to the first gradational cavity; each gradational cavity including a plurality of polygonal holes gradationally contracted in sizes inwardly from an outermost hole towards an innermost hole; whereby a plurality of polygonal holes having plurality of hole sizes may be conveniently chosen for fastening a bolt or nut by correspondingly matching the bolt (or nut) size with the polygonal-hole size.

主权项

1. A socket comprising: a socket body, a first gradational cavity recessed in situ in a first end of the socket body, a second gradational cavity recessed in situ in a second end of the socket body opposite to the first gradational cavity, and an intermediate hole formed through the socket body and formed in between the first gradational cavity and the second gradational cavity adapted for inserting a driving rod into said intermediate hole for rotatably driving said socket body;
each said gradational cavity including a plurality of polygonal holes gradationally contracted in sizes inwardly from an outermost polygonal hole towards an innermost polygonal hole in each said gradational cavity; and an innermost polygonal hole of said first gradational cavity being larger in size than an outermost polygonal hole of said second gradational cavity.
