WIPO Patent Application WO/2023/090524
Kind Code:
A1
Abstract:
According to an embodiment of the present invention, a coupling device used to implement a gear-box replacement-type electric torque wrench comprises a coupling socket (100) which comprises: a socket shaft (110) coupled to a motor rotary shaft of an electric motor loaded in a main body casing (10) of the electric torque wrench; and a socket body (120) which is installed on a gear-box coupling surface (11) of the main body casing (10), the gear-box coupling surface (11) corresponding to a coupling portion to a gear-box (20). Also, the coupling device used to implement the gear-box replacement-type electric torque wrench, may comprise a coupling adaptor (200) which is installed on a main body coupling surface (21) of the gear box (20), the main body coupling surface (21) corresponding to a portion coupling to the main body casing (10), and is attachably/detachably coupled to the coupling socket.
