Abstract (en)
A socket (1) includes a plurality of protrusions (14) circumferentially disposed around a circular top opening (11) of the socket (1), whereby upon insertion of a driving shaft (2) of a spanner or the like, the driving shaft (2) will be respectively biased or thrusted by the protrusions (14) and then smoothly guided into a square hole (12) of the socket (1) for quickly coupling the driving shaft (2) in the socket (1). The socket (1) further includes plural bottom protrusions (14b) disposed around a circular bottom opening (11b) in a bottom portion of the socket (1), and eighteen faces formed in a hexagonal bottom hole (12b) of the socket (1) for helping a quick coupling of a nut or bolt (3) into the bottom hole (12b) of the socket (1).
