Multifunctional through sleeve

The invention belongs to the field of mechanical tool equipment, and particularly relates to a multifunctional through sleeve. The multifunctional through sleeve comprises a sleeve body and a rotatingsleeve, the sleeve body is detachably connected with the rotating sleeve through a connecting block, the connecting block is in threaded connection with the rotating sleeve, one end of the connectingblock is rotationally connected with the sleeve body through a limiting piece, a sealing ring is arranged at the other end of the connecting block in a matched mode, an inner sleeve is detachably connected to one end, away from the connecting block, of the sleeve body, and a clamping piece is arranged between the sleeve body and the rotating sleeve. By arranging the multifunctional through sleeve, the sleeve can be flexibly replaced according to actual assembly requirements during assembly operation of equipment, so that quick switching between two types of assembly operation of a screwdriverbit and the sleeve is realized, the assembly efficiency is greatly improved, frequent replacement of operation tools during each assembly operation of the equipment is avoided, the equipment assembling difficulty is effectively reduced, automatic multifunctional assembling work of the equipment is achieved, and the multifunctional through sleeve is suitable for popularization in a wide range.
