1. A tool for the application of pressing wedges in wedge-type levelling spacer systems used in the application of tiles and that are equipped with a base block and a pressing wedge, wherein the tool comprises:
a handgrip comprising a front end from which projects a support rod having a longitudinal axis;
a slider constrained to the support rod and at least partially delimiting a through opening configured to slidably receive at least one axial segment of the pressing wedge;
a thruster associated with the handgrip in a movable manner at least along a thrusting direction parallel to the longitudinal axis of the support rod between an advanced position, wherein the thruster is proximal to the slider, and a withdrawn position, wherein the thruster is distal from the slider; and
a mechanical actuator associated with the handgrip and configured to actuate the thruster at least from the withdrawn position to the advanced position,
wherein the handgrip has an inner chamber, and
wherein the mechanical actuator is chosen from the group constituted by a pneumatic actuator and an electric actuator and comprises a fixed body rigidly fixed to the handgrip within the inner chamber thereof.
