Screw keys with a surprising clamping connection

摘要

Screw key with a surprising clamping connection, which has a main body (10) with a key head (11), where a recording room (12) is formed in the key head, in which there is a Council element (20), and where the Council element (20) has a hexagonal groove (21) which is at the bottom with a wider is circular groove (22), with an inner cornering (24) at the hexagonal sides of the hexagonal groove (21), each having a cylindrical groove (23) at corners of the hexagonal grooves (21),and where at the top of the hexagonal groove (21) a small hexagonal passage hole (25) is formed;where the hexagonal node (21) of the Council element (20) provides for a nuchal positioning element (30), having a top section (32) and a bottom hexagonal positioning section (31), and where a hexagonal hole (37) passes through the nuchal positioning element (30), and where a positioning cylinder (33) is positioned at corners of the six-angle positioning section (31) and where a steel ball (35) is located in the middle of two opposite sides of the six-angle positioning section (31) each, a steel ball hole (34) is formed; and where a ring nut (36) is formed at the outer edge of the upper end of the upper part (32);where, when the nut positioning element (30) intervenes from the bottom end of the Council element (20), its hexagonal positioning section (31) and its positioning cylinder (33) are limited in the hexagonal node (21) and the cylindrical node (23), where a spring (26) is provided on the positioning cylinder (33) in the cylindrical groove (23); andwhere the upper section (32) of the nut positioning element (30) emerges from the hexagonal passage hole (25) of the Council element (20) and then intervenes in a passage opening (41) of a control disc (40), and a fixing element (43) is inserted into the ring nut (36) of the nut positioning element (30), that the fixing element (43) is applied to the upper end surface of the steering wheel (40), causing the steering element (20),the nut positioning element (30) and the control disc (40) are connected to each other.
