Disclosed is a novel high frequency tuning slide-type electrical contact tip, comprising a tuning ring which slides between an outer sleeve and an inner sleeve, the outer sleeve being sleeved on the inner sleeve, the tuning ring being composed of an inner elastic piece, an upper base, an outer elastic piece and a lower base, the upper base and the lower base being soldered as one, the inner elastic piece and the outer elastic piece being uniformly arranged along the axial direction and soldered onto the lower base, an upper side surface of the upper base being soldered to a pull rod, an upper end of the pull rod being driven by a motor to move up and down, so that the tuning ring slides up and down between the outer sleeve and the inner sleeve along the pull rod. The novel electrical contact tip solves problems such as gaps being too small and operations being too difficult during cyclotron high frequency system tuning ring adjustment. The overall structure is simple, compact and affordable, effectively reduces joule heating produced by contact resistance, prevents contact surface welding or conduction damage, and is especially suitable for use in small gap range tuning.
