Beschreibung
Zusammenfassung:	The invention provides a connecting device for detecting torsion. The connecting device for detecting the torsion comprises a sleeve elastically distortional in the radial direction under the external force effect and a pressing assembly which is connected with the sleeve in a sealed mode and applies pressure to the sleeve. The pressing assembly comprises a cylinder, a storage cavity for filling with compressing media is formed in the cylinder, a working cavity which is communicated with the storage cavity and extends in the axial direction of the sleeve is formed in the sleeve, a pushing part for pushing the compressing media in the direction of the sleeve is also arranged on the cylinder, the sleeve is rotated or inserted into a threaded hole or a light hole in an insert, the pushing part moves in the direction of the sleeve to allow pressure in the storage cavity to be enlarged so that hydraulic oil or gas can enter the working cavity, the pressure in the working cavity is enlarged to allow the sleeve to b
