Description

Sleeve with stable connection Technical Field The utility model relates to the technical field of sleeves, in particular to a sleeve with stable connection. Background The magnetic sleeve is a tool sleeve combining magnetic functions and is mainly used for adsorbing and fixing metal parts (such as screws, nuts and the like) so as to improve the operation efficiency and reduce the risk of part loss. Through retrieving, chinese patent discloses a smooth magnetism deepening sleeve (grant bulletin number CN 210255896U), including hexagon socket head cap and connecting axle, hexagon socket head cap's one end axial be provided with the connecting axle, hexagon socket head cap's inside axial install the sliding block, sliding block's one end and hexagon socket head cap's inboard bottom between install the spring, sliding block's the other end terminal surface embedding between two parties install magnet, this patent technology is although having solved the inconvenient use that fastener length led to, built-in C shape hoop can prevent that the magnet from coming off and the problem of smooth silk. However, the device still has some defects when in actual use, and is more obvious that the current sleeve adopts a hexagonal inner hole and spring steel ball locking structure, the steel balls are clamped into the annular groove of the electric batch output shaft to realize fixation, however, the contact area of the steel balls and the groove is limited, radial displacement is easy to occur under the working condition of high torque or vibration, the connection stability is reduced and even the connection is accidentally separated, the current sleeve is mostly formed integrally, and after the current sleeve is used for a long time, the magnets in the sleeve are worn and corroded, so that the magnets in the current sleeve are difficult to replace. Disclosure of utility model In view of the foregoing problems in the prior art, a primary object of the present utility model is to provide a sleeve with a stable connection.
