The elastic member 300 is disposed in the needle tube 200 and has a constant tendency to urge the needle 100 out of the nozzle 210, so that the needle 100 can elastically stretch and retract relative to the needle tube 200, thereby meeting the purpose of elastically abutting the needle 100 against an external electronic component to realize electrical connection.

Magnetic element 400 is provided in needle tube 200, and magnetic element 400 may be a magnet or a magnetizer. Magnets generally refer to substances having their own magnetic field, such as needle magnets, electromagnets, etc., which are capable of generating a stable and durable magnetic field. The magnetic interaction of atoms or molecules within a magnet is a dominant factor. The magnetizer refers to materials capable of conducting magnetic fields, such as metals of iron, nickel, cobalt and the like, and ceramic materials of ferrite and the like. The feature of the magnetic conductors is that they can change their own magnetism by introducing an external magnetic field, that is to say they are more sensitive to external magnetic fields.

The magnetic member 400 may be disposed between the elastic member 300 and the needle 100, where one end of the magnetic member 400 abuts against the needle 100 and the other end abuts against the elastic member 300. The magnetic member 400 is pushed by the needle 100 to compress the elastic member 300, or the elastic member 300 recovers elastic deformation to push the magnetic member 400 so that the needle 100 is reset, thereby realizing elastic telescopic movement of the needle 100 relative to the needle tube 200.
